Pablum from Pence on space

12:31 pm

If you want to waste about about 25 minutes of your life, you can listen to the speech that Vice President Mike Pence gave today at the Kennedy Space Center here, beginning at the 49:30 minute mark.

My advice is that you don’t do it. Pence said nothing. He handed out a lot of empty promises and cliches, without any specifics or details of any kind. He confirmed for me what I have suspected of Pence for several years, that despite the fact that he lives and breathes a conservative and honorable personal life, as a politician he is a hack.

He made a big deal about the recreation of the National Space Council, which he now leads. However, as this article by Eric Berger properly noted the people who seem to be exerting the most influence on that council, on Trump, and on Pence are from the big space companies that have spent more than a decade and a half spending about $40 billion trying to build a big rocket (SLS) to fly a single unmanned test flight of the Orion capsule.

My pessimism here might be misplaced. We still do not know who will be on this space council. Furthermore, the Trump administration has been very good at doing a lot of public relations and soft stroking of its opponents in order to put them off guard prior to hitting them hard, where it hurts. This might be what Pence was doing here.

Nonetheless, the lack of any substance in Pence’s remarks makes me fear that he will be easily influenced by the big players who simply want the federal cash cow to continue sending them money, whether or not they ever build anything.

As predicted climate scientists begin adjusting satellite data to fit models

12:37 pm

If the facts don’t fit the theory, change the facts! The scientists in charge of the climate satellite data produced by Remote Sensing Services (RSS) in California have decided to adjust their satellite data to increase the warming trend since 2000 and make that data more closely match the surface temperature data that NASA and NOAA have already altered to show that same warming trend.

Researchers from Remote Sensing Systems (RSS), based in California, have released a substantially revised version of their lower tropospheric temperature record. After correcting for problems caused by the decaying orbit of satellites, as well as other factors, they have produced a new record showing 36% faster warming since 1979 and nearly 140% faster (i.e. 2.4 times larger) warming since 1998. This is in comparison to the previous version 3 of the lower tropospheric temperature (TLT) data published in 2009.

How have they done this? They made several changes, the first two of which appear quite questionable. First, they addressed the “time of observation issue.” There is a belief among some climate scientists that the time temperature readings were taken can introduce an error in the long term trends.

To account for changes in observation times, the RSS group used a number of different approaches and models to try and estimate what the temperature would have been if the measurement time remained constant. This involves a combination of satellite observations (when different satellites captured temperatures in both morning and evening), the use of climate models to estimate how temperatures change in the atmosphere over the course of the day, and using reanalysis data that incorporates readings from surface observations, weather balloons and other instruments.

Depending on the time of the observation correction approach chosen, the resulting temperature trends between 1979 and 2016 ranged from as low as 0.13C per decade to as high as 0.22C per decade. The RSS group ultimately decided that the most reasonable set of parameters give a temperature trend of 0.17C. [emphasis mine]

I am puzzled by this, since satellites in orbit do not take readings at one particular time, but at a wide range of times. In fact, I would say that the number of readings, at all different times, would easily introduce enough randomness into the results that any error would be insignificant. Instead, these scientists have decided to adjust the raw data to add a warming trend of almost a tenth of a degree centigrade.

Next, they simply decided that the data coming from some satellites should be excluded.

A river canyon on Mars

11:02 am

A river on Mars

Cool image time! The image on the right, reduced in resolution significantly to show here, was taken by the Themis camera on Mars Odyssey, and shows an unnamed canyon on Mars. Be sure to click on the image to see the full resolution version.

This canyon of course no longer has anything flowing in it. Moreover, it is not clear whether this was formed by water or lava. Unfortunately, the image is part of a series of “Art images” from Mars Odyssey, where they pick an image and suggest it looks like something else. In this case, they are claiming this looks like a “snake, slithering down the image.” Cute, but not very helpful. And unfortunately, they don’t add any further details at all about the image or its location. The context image suggests this canyon is next to a volcano.

After doing further research at the Themis image site, I was able to locate this image on Mars (using latitude 32.0515 and longitude 152.236 given at the link) and look at the images surrounding this one. Further research identified the volcano as Hecates Tholus in the Elyesium Plantia region to the west of Mars’s giant volcanoes.

Looking at all the nearby Mars Odyssey images, it appears that there are a lot of flows like this in this area, and all of them appear to be lava flows, with this one being the largest. A close look at the area just to the south of where the deep canyon opens out shows that the small surface flow draining into the canyon also appears to sit on much larger surface flows (at least two) that left the surface higher than the surrounding terrain.

Elyesium Plantia itself is a plateau, somewhat close to the border between Mars’s southern highlands and the northern plains where some scientists think an ocean might have once existed. Thus, it makes sense that the canyon drains north, as it is following the dip down to those northern low plains.

Mars rover update: June 23, 2017

11:11 am

Summary: Curiosity continues up hill. Opportunity has wheel problems.

Curiosity

For the overall context of Curiosity’s travels, see Pinpointing Curiosity’s location in Gale Crater.

The march up Mt Sharp continues. Since my last update on May 15, Curiosity has continued working its way up towards what the science team has named Vera Rubin Ridge, the beginning of a lighter, yellowish layer of rock, dubbed the Hematite Unit, that sits higher up the mountain’s slope. They have been traveling on the Murray Formation now for more than a year, since March, 2016, so entering this new layer of geology is eagerly anticipated by the science team. (This October 3, 2016 press release. gives an overall picture of the geology Curiosity is traversing.)

Reader Phil Veerkamp sent me a beautiful panorama he stitched together from recent Curiosity images of Vera Rubin Ridge, directly to the south of the rover and higher up hill. Below is a reduced resolution version. Be sure you click on it to explore the full resolution image. This is a new type of terrain, significantly different than anything Curiosity has seen up to now. It also appears that the rover will see far less dust, and might be traveling mostly over solid boulders. Below I have cropped out a very small section of the ridge line near the center of the full image, just to illustrate this.

It’s the hate, not the violence

1:50 pm

The last few days have probably been the ugliest I have ever seen in American culture. Not only was an attempt made to commit mass murder against a group of Republican elected officials, the response from too many mainstream Democrats has generally been tone deaf and even supportive of the violence. Worse, the violence appears to be on-going, with no sign of relief.

My list is hardly complete. The stories above are only a small sampling of the ugly stuff I have read since the shooting on June 14. The best I have seen from some Democrats is a hint that maybe they have let their rhetoric get out of hand, but even here they often backtrack to blame Republicans and only Republicans for the shooting.

Are Republicans innocent here? No. The coarseness of language and increasing anger I have seen from both sides in the past six months has been appalling. Rather than respond strongly but intelligently and with civility, too many Republicans have decided they can be as harsh and as coarse and as vicious as the Democrats.

Nonetheless, the bulk of the coarseness and viciousness and violence falls mainly to the Democratic and liberal side of the political spectrum. You need only scan this list of attacks against conservatives since in the past year, many of which I have noted here on Behind the Black. The left has been getting increasingly violent, with no protest by the left’s leaders in the Democratic Party. Even an attempted mass murder seems insufficient to cause much horror or shame in Democratic and leftwing circles.

The key to all this however is the single word I have highlighted in the fourth headline link above. That word is “hate.” What is motivating all of this violence and ugliness is hate, a blind irrational emotion that now prevents these people from looking at reality coolly. Trump is “evil.” He is a “nazi.” He is an “anti-Semite.” He is “racist.” He wants to “kill sick people.”

None of this is true. Trump is surely not the most ideal person to be our president at this moment of time, but he is also not any of the terrible things the left is accusing him of being.

Facts and rational thought however no longer matter to the left. They hate, and their hatred can now be used to justify almost any act, including an attempt at mass murder. This is beyond the pale, and it is turning the left into everything it has said it opposes for the past century: bigoted, hateful, violent, and oppressive. They had better cool their minds down a bit or else they will find themselves in the middle of hellstorm, targets themselves, with no way to control it.

One more thought. Right after the Tucson attack on Congresswoman Gabby Giffords in 2011, I noted the disgusting inflammatory language of the left. They demanded civility from conservatives, while simultaneous calling for their murder. I said then that they had better tone down their rhetoric or face a firestorm that they themselves might not survive.

This behavior must stop. Violent and angry rhetoric can and will cause violence. And it probably has, considering the fact that a large number of the random violent acts in recent years have actually been committed by deranged individuals with liberal, not conservative, leanings. This is not to say that I blame the left for this violence, but that the left has as much of a responsibility as the right to think carefully about what it says, before it says it. Otherwise, they might find that they have made their less rational followers more angry than they ever imagined, or can control.

Or as Michael York says to his Nazi friend at the end of this scene from the 1972 movie, Cabaret. “You still think you can control them?”

We are now six and a half years later, and instead of toning down their rhetoric, the left has escalated it to violence and murder. They have embraced their hate, and it is making them insane.

Using math to protect the Washington power structure

8:58 pm

What could possible go wrong? A group of mathematicians have written software designed to prevent the gerrymandering of congressional districts, and are offering that software as a weapon for the courts to force states to revise the districts, even though those districts were created by fairly elected state legislatures.

Leaning back in his chair, Jonathan Mattingly swings his legs up onto his desk, presses a key on his laptop and changes the results of the 2012 elections in North Carolina. On the screen, flickering lines and dots outline a map of the state’s 13 congressional districts, each of which chooses one person to send to the US House of Representatives. By tweaking the borders of those election districts, but not changing a single vote, Mattingly’s maps show candidates from the Democratic Party winning six, seven or even eight seats in the race. In reality, they won only four — despite earning a majority of votes overall.

Mattingly’s election simulations can’t rewrite history, but he hopes they will help to support democracy in the future — in his state and the nation as a whole. The mathematician, at Duke University in Durham, North Carolina, has designed an algorithm that pumps out random alternative versions of the state’s election maps — he’s created more than 24,000 so far — as part of an attempt to quantify the extent and impact of gerrymandering: when voting districts are drawn to favour or disfavour certain candidates or political parties.

There are numerous problems here, all of which center on my basic disbelief in the non-partisan objectivity of these scientists and their work.

First, note the first example used. Mattingly proudly shows how his software demonstrates that Democrats could have won more districts in North Carolina. In fact, if you read the article, he claims that the district revisions produced by his software (producing more victorious Democrats) creates fairer districts than the districts created by the state’s fairly elected Republican legislature. Moreover, it was the Republican redistricting that prompted this mathematician to write the software.

Funny how he never felt compelled to do this when it was Democrats controlling the legislatures and gerrymandering the congressional districts to their benefit.

Second, he has offered this software to the courts as evidence to overrule the redistricting done by fairly elected legislatures. In other words, this software will be used to justify letting unelected experts decide how congressional districts should be shaped, not elected officials picked by voters.

Third, note who has expressed interest in using this mathematician as a witness to win its lawsuits:

Washington rallies around the Outer Space Treaty

1:52 pm

Yesterday Senator Ted Cruz (D-Texas) held the second in what he says will be a series of hearings on the future government regulation of the commercial space industry. The specific focus of this hearing was the 1967 Outer Space Treaty and its effect on private enterprise.

The hearing saw two panels of witnesses, the first three legal experts on the Outer Space Treaty, the second four industry experts from a variety of private space businesses.

Like the first hearing on April 27, the witnesses this time were once again unanimous in their call for a simplification of the present regulatory arrangement. They also emphasized repeatedly that private enterprise should not be required by Congress to get permission to do things in space. Instead, Congress should merely provide regulation that will facilitate private enterprise while helping them avoid interfering with each other.

Unlike the first hearing, however, the atmosphere was decidedly less interested in improving the overall international regulatory framework created under the Outer Space Treaty. Instead, the witnesses in unison were supportive of the treaty and did not want the U.S. to either pull out of it or try to change it. All advocated the position that the treaty as written allowed the U.S. to regulate private businesses in a manner that could protect property rights in space.

As I watched the hearing I was struck by this unity of position. To me, it appeared that the Washington elitist community was circling its wagons in order to protect the status quo.

The witnesses from the business community appeared afraid of the consequences of any effort to change the Outer Space Treaty. As Mike Gold, Vice President of Space Systems Loral, noted,

Trump budget released only to be immediately trashed

11:22 pm

Today the Trump administration released its proposed 2018 budget for the federal government. Here is a good article on what that budget proposed for NASA.

The Trump administration’s fiscal 2018 budget request includes $19.1 billion for NASA, a $561 million decrease over previously enacted levels that would reduce the number of Earth science missions, eliminate the agency’s education office and do away with the Obama administration’s plans to robotically retrieve a piece of an asteroid as a precursor to eventual flights to Mars.

The budget closely reflects the administration’s blueprint, released in March, and overall, NASA’s acting administrator said America’s space program remains healthy and suffered relatively modest cuts compared to other federal agencies.

Though the NASA budget did include the cancellation of a handful of Earth Science projects as well as a cut in the Earth science budget, those cuts were nowhere near what had been hinted at previously.

The Trump administration has made no secret of its skepticism about global warming and its presumed causes and impacts and as expected, the budget eliminates funding for five Earth science missions and instruments. Earth science would receive $1.8 billion overall, reflecting a reduction of nearly $170 million. “The hard choices are still there, and we can’t do everything,” Lightfoot said. But the budget “still includes significant Earth science efforts, including 18 Earth observing missions in space as well as airborne missions.”

That’s a reduction of less than 10% in the total Earth science budget, hardly a catastrophe. The overall budget proposal was a little more daring, calling for a 30% cut at the EPA, and a 16% cut at Commerce, mostly in NOAA.

What does this all mean? Nothing. A president’s budget proposal is generally only a statement of desires. It has no force of law. Congress decides how to spend money, and the Republicans controlling this Congress are not really interested in cutting anything. In fact, the pigs have already begun to squeal, including a complete rejection of the budget by many Republican leaders in Congress.

‘President Trump’s $603 billion defense budget request is inadequate to the challenges we face, illegal under current law, and part of an overall budget proposal that is dead on arrival in Congress,’ said Arizona Sen. John McCain.

The administration didn’t seem to signal its own vote of confidence by releasing the document during President Trump’s first overseas trip.

Longtime GOP Rep. Hal Rogers of Kentucky, a longtime appropriator, declared proposed cuts to safety net and environmental proposals ‘draconian.’

‘I don’t think the president’s budget is going anywhere,’ said Republican Sen. Bill Cassidy of Louisiana, asked if he’s concerned about the message sent by slashing the Medicaid program for the poor and disabled.

That’s only a sampling. Essentially, these Republicans have no interest in gaining control of the out-of-control federal budget. They like having that budget out-of-control, as it feeds money to their friends and partners whom then line their pockets with campaign contributions.

I should note that I fully expect Trump to bow to their demands, and back off. When it has come to budget matters, he has so far shown no stomach for the fight.

The bigotry that dominates today’s colleges

1:35 pm

I have been collecting stories over the past two weeks that highlight the horrible spread of bigotry and prejudice, based merely on race, on many of today’s college campuses. Here are a few of those stories.

This list includes colleges in numerous states, from ivy league institutions to public colleges and private universities. Worse, in every case it appears that the school administrations either actively support the bigotry, condone it, or passively do nothing to oppose it.

This list of course is hardly complete. However, I compiled it to illustrate that the daily stories coming from today’s college campuses illustrate a frightening trend that can be seen across the entire country. What is horrifying is that I compiled it in just a little over a week. I have no doubt that should I continue compiling the list I will find that the list of colleges supporting this bigoted behavior, almost all of which is illegal under the Civil Rights Act (not to mention morally repugnant), will grow significantly. I expect that every college in the United States that takes federal dollars is dominated by this race-based hate. Worse, that hate is growing and becoming more violent and fearless in its blatant desire to oppress those it hates.

The time has come to cut off all tax dollars to these places. Donations from alumni should cease. Parents should refuse to send their children there.

If we do not stand up against this evil, it will soon consume us. The warning signs are there. And it has happened before. We will have no one to blame but ourselves if we do nothing.

GAO: Cost and scheduling problems with many big NASA projects

1:07 pm

A new Government Accountability Office audit [pdf] that reviewed 22 major NASA projects, including Orion and SLS, has found that many of them have significant scheduling and cost problems.

Let’s just go through them all:

  • SLS: “The SLS program’s schedule is deteriorating and it is at increased risk of exceeding its cost baseline and missing its November 2018 launch readiness date.”
  • Orion: “The Orion program is increasingly at risk of missing the November 2018 launch date for its first uncrewed exploration mission.”
  • Mars 2020: “The Mars 2020 project has not met key best practices for reducing product development risk.”
  • Asteroid Redirect Robot Mission (ARRM): “In August 2016, the ARRM project entered the preliminary design and technology completion phase with a higher cost and longer schedule than previously estimated.”
  • Europa Clipper: “At the project’s most recent decision review, its independent review board stated that it was at risk of exceeding its preliminary cost and schedule ranges unless its scope or complexity was reduced.”
  • Ground Systems (EGS) upgrade: “The EGS program’s schedule is deteriorating and it is at increased risk of exceeding its cost baseline and missing its November 2018 launch readiness date.”
  • ICESat-2: “The ICESat-2 project has encountered problems with the flight lasers in its sole instrument—the Advanced Topographic Laser Altimeter System (ATLAS)—that will likely cause it to miss its committed launch date and could cause it to exceed its current cost baseline.”
  • InSight: “The InSight project missed its committed launch date of March 2016 and exceeded its cost baseline due to technical issues with its primary science payload—the Seismic Experiment for Interior Structure (SEIS) instrument—which is contributed by the French space agency (CNES).”
  • Ionospheric Connection Explorer (ICE): “The ICON project has experienced technical issues and delays in system integration and testing, but it still on track to launch in July 2017—3 months earlier than its committed launch date.”
  • James Webb Space Telescope: “In December 2016, we found that the primary threat to the JWST project continues to be the ability of the observatory development and integration contractor, Northrop Grumman, to control its costs.”
  • Radiation Budget Instrument (RBI): “NASA’s joint cost and schedule confidence level analysis indicated that the likelihood of the project meeting the date is low and the project’s independent review board described the schedule as optimistic when compared to similar instruments. … The RBI project’s prime contractor Harris continues to experience cost overruns.”
  • Space Network Ground Segment Sustainment (SGSS): “The SGSS project has exceeded the new cost and schedule baseline NASA set for it in June 2015 and further cost and schedule growth is likely.”

Not all the projects audited were a disaster. GRACE-FO, Landsat-9, NISA, Solar Probe Plus, SWOT, TESS, and WFIRST have few significant problems, though even with these there have been delays with each project still facing significant cost and scheduling risks.

As for Commercial Crew, the audit notes delays and problems, but these appear to be mostly linked to the bureaucratic and somewhat unjustified demands by NASA for increased safety, such as the agency’s refusal to accept the use of the Atlas 5 with a Russian first stage engine and its concerns about SpaceX’s plans to fuel the rocket with astronauts on-board (even though astronauts have been aboard fueled rockets with every other manned launch for the entire history of space exploration).

Overall, this audit does not speak well of either NASA’s management or the contractors with whom the agency has routinely worked. Space engineering is hard, but many of these problems seem more related to either incompetence or a willingness of NASA to forgive bad work too often. The number of contractors or government agencies listed here who have failed entirely at their jobs is appalling.

Mars rover update: May 15, 2017

12:31 pm

This update could also be entitled, “Up and down into Martian gullies,” as that is what both rovers, Curiosity and Opportunity, are presently focused on doing.

Curiosity

Curiosity's position, Sol 1696 (May 12, 2017)

For the overall context of Curiosity’s travels, see Pinpointing Curiosity’s location in Gale Crater.

In the past month, since my previous April 21, 2017 update, Curiosity has been working its way up the dry wash, frequently stopping to inspect the rocky surface terrain within. As they note,

As we climb up Mount Sharp, recently over slopes of 4-6 degrees, we have seen more varied outcrop structures and chemistries than the rest of the Murray formation, and such changes catch the collective eye of the team.

Only in the last week have they shifted to the east, as planned. Their near term goal is the lighter, yellowish layer of rock, dubbed the Hematite Unit, that sits higher up the slope of Mount Sharp. As they have been traveling on the Murray Formation now for more than a year, since March, 2016, I am certain the science team is even more eager to get to this different layer of geology to find out what it is made of and why it is there.

You can get an overall view of the geology Curiosity is traversing from this October 3, 2016 press release. Below is a version of the traverse map shown at that site that I posted as part of my October 6, 2016 rover update, updated to show Curiosity’s present location. It is apparent that Curiosity is finally moving out of the foothills below Mount Sharp and beginning its climb up the mountain’s actual slopes.

The press begins to turn against SLS

5:28 pm

This report by Eric Berger of Ars Technica, describing the press teleconference today where NASA announced that they would not fly humans on the first SLS flight in 2019, reveals a significant political change.

In the past, most mainstream reporters would routinely accept NASA’s announcements about SLS. If the agency said it was great, their stories would wax poetic about how great it was. If NASA said its greatness was causing a delay, their stories would laud NASA had how well it was doing dealing with SLS’s greatness, even though that greatness was forcing another delay. Never, and I mean never, would NASA or these reporters ever talk about the project’s overall and ungodly cost.

This press conference was apparently quite different. The press had lots of questions about SLS and its endless delays. They had lots of questions about its costs. And most significant, they had lots of questions for NASA about why the agency is having so much trouble building this rocket, when two private companies, SpaceX and Blue Origin, are building something comparable for a tenth the money in about half the time.

During the teleconference, Ars asked Gerstenmaier to step back and take a big-picture look at the SLS rocket. Even with all of the funding—about $10 billion through next year—how was the agency likely to miss the original deadline by as much as three years, if not more?

“I don’t know,” Gerstenmaier replied. “I don’t know—I would just say it’s really kind of the complexity of what we’re trying to go do, and to build these systems. We weren’t pushing state-of-the-art technology, like main engines sitting underneath the rocket or new solid rocket boosters. But we were pushing a lot of new manufacturing, and I think that new manufacturing has caused some of the delays we’ve seen. No one welds the way that we’re welding material at the thicknesses we’re welding.”

…Later, the NASA officials were asked about private companies such as SpaceX and Blue Origin, which are also building heavy-lift rockets but at a very limited cost to taxpayers. What would they have to say about just buying those vehicles off the shelf, at significantly lower cost than an SLS launch, and preserving NASA’s funds to execute in-space missions?

Gerstnmaier’s explanations for SLS’s delays and costs, that it is a very complex and advanced piece of rocket engineering, is total bunk. This was supposed to be an upgraded Saturn 5, but it will only be able to lift about 70% of the payload. It is using the actual shuttle engines, and upgraded shuttle solid rocket boosters. While new engineering was required to refit these for SLS, none of that should have been so hard or expensive.

The key here is that members of the press are finally aware of this, and are asking the right questions. With Falcon Heavy about to launched multiple times before SLS even launches once, the continuation of this boondoggle is becoming increasingly difficult to justify.

The soft avalanches of Mars

9:23 am

Krupac Crater gullies

Cool image time! The image on the right, reduced in resolution to show here, shows the gullies flowing down Krupac Crater on Mars. Be sure to check out the original, released today by the Mars Reconnaissance Orbiter science team, since they have enhanced the colors to bring out the sandy flows, noting as well that while most of these gullies are found in higher latitudes, this crater at 7.8 latitude has them as well.

Although large gullies (ravines) are concentrated at higher latitudes, there are gullies on steep slopes in equatorial regions. An enhanced-color closeup shows part of the rim and inner slope of Krupac Crater located just 7.8 degrees south of the equator.

The colors of the gully deposits match the colors of the eroded source materials. Krupac is a relatively young impact crater, but exposes ancient bedrock. Krupac Crater also hosts some of the most impressive recurring slope lineae (RSL) on equatorial Mars outside of Valles Marineris.

Below I have cropped out a small section showing, at full resolution, the termination point of one of these flows, indicating where this section is on the larger image to the right. This avalanche is clearly not liquid, though it has a very sandy and soft nature, suggesting — as some scientists have theorized — that liquid from below the surface might have played a part in its flow.

It is important in looking at these images to repeatedly remind yourself that the gravity here is about one third that of Earth, and thus the angle of repose will be different, and that avalanches will behave very differently in this environment. Moreover, Mars’s far colder climate will also effect things. The avalanche we are looking at could not happen in this way on Earth.

The coming fascism

11:02 am

This post will be a very pessimistic one. In the last twenty-four hours I watched two different videos, both of which illustrated the growing close-mindedness in American society. On one hand we watch while a high school assistant principal does everything he can to not talk reasonably to two students holding signs opposed to abortion. First he tries to get them to leave, claiming they don’t have the right to stand there (they do, as it is a public street and there is something called the first amendment protecting their right to speak). Then he accuses them of harassing people, which it is very clear from the video they are doing no such thing. Finally, he stands there trying to prevent others from seeing their signs, while yelling “La-la-la-la-la-la-la!” loudly to keep others (and himself) from hearing what they say. He really does this.

On the other we have a detailed video report from the Foundation for Individual Rights in Education (FIRE) about the alarming hostility to free speech at Tufts University. This quote from the video struck me as downright terrifying for our future:

The climate at Tufts embodies several trends FIRE has seen growing in recent years. There is a shift away from the heavy-handed administrators posing the biggest threat to free speech on campus. Now the loudest calls for censorship are coming from the students themselves. … And in some cases like we saw first hand at Tufts, students are equating offensive or uncomfortable speech with violence. [emphasis mine]

Both videos are embedded below the fold. Please spend the time to watch both. I think you will be equally terrified. The left not only can no longer tolerate listening to any dissenting opinions, they have created a culture and mindset among the younger generation that makes dissent and freedom of speech downright impossible. And both the adults and the students of this intolerant culture are moving with increasing aggressiveness to try to shut down any opposing speech, sometimes with outright violence.

Space, regulation, the Outer Space Treaty, and yesterday’s Senate hearing

9:27 am

Yesterday the space subcommittee of the Senate Commerce committee held a hearing, organized by Senator Ted Cruz (R-Texas), entitled “Reopening the American Frontier: Reducing Regulatory Barriers and Expanding American Free Enterprise in Space.”

You can watch the hearing here. There have also been a number of stories last night and today that summarized the testimony during this hearing.

Having watched the full hearing, I think that most of these stories did not capture well the full political context and significance of yesterday’s event. They focused on Cruz’s advocacy for private space and the call for less and more streamlined regulation by the witnesses. They missed a great deal else.

A look at some Israeli West Bank settlements

2:22 pm

As my regular readers know, I periodically take trips to Israel to visit family. When I return, I then post my impressions and what I have learned, thereby providing an eye-witness perspective to the Israeli-Palestinian conflict. Previous essays from earlier visits are as follows, with the first five from my 2013 visit and the last from my visit in 2014:

Map of the West Bank settlements that I have visited

Having just returned from another visit, I have some new impressions. Above all, I think it worthwhile to note that in all these visits, I have routinely stayed with relatives who live in West Bank settlements. In fact, I have now visited or stayed in five different settlements. The map on the right shows the locations of these settlements, marked with an X. If you click on the image you can see a higher resolution version.

Unfortunately, I do not remember the name of the settlement from my 2003 visit, though I know it was west of Hebron. It might have been Carmel, but I am not sure. I do know I have indicated its location with reasonable accuracy.

Regardless, there are a number of things we can learn from my visits. The largest settlements, Alon Shvut, Kiryat Sefer, and Beitar, are all close to the 1949 Armistice border. They are also all relatively close to Jerusalem and thus act for many as suburbs of that larger city. As I wrote in 2013,

Mars rover update: April 21, 2017

1:00 pm

Curiosity

Curiosity's position, Sol 1664 (April 10, 2017)

For the overall context of Curiosity’s travels, see Pinpointing Curiosity’s location in Gale Crater.

Since my previous February 14, 2017 update, Curiosity has worked its way through the dunes and has emerged, as planned at the head of what looks like a dry wash flowing down from Mount Sharp. At the time I had predicted that the science team would then have the rover make a beeline to Mount Sharp, following the smoothest route. That prediction is almost certainly wrong. Instead, the scientists are probably going to have the rover zig-zag its way south into the dry wash so that they can study the geology there. This is what they have been doing, as shown on the traverse map to the right, which shows Curiosity’s location through Sol 1664 (April 10). Ideally I expect them to want to check out the flow areas of the central parts of the wash as well as the contact point on either side where the color of the terrain changes from dark to light. This appears to be what they doing now, two weeks later, based on this update posted yesterday.

The 23 m drive on Sol 1673 put Curiosity alongside Murray bedrock blocks that appeared to be capped with a different material, with a darker color and smoother texture relative to the Murray

The storms of Jupiter

9:26 am

The storms of Jupiter

Cool image time! The image on the right, taken by Juno during its fifth close fly-by of Jupiter in late March and cropped to post here, shows two of the major storms in what I think is one of Jupiter’s main large mid-latitude belts. The full image, posted below in a significantly reduced form but annotated by me to indicate the location of the inset, covers a much larger area, but I have specifically zoomed into these two storms to highlight how large these storms are as well as how much detail is hidden within them.

In the bright spot in particular (officially called A6 by planetary scientists) you can see a hint of the existence of innumerable mini-storms. Juno’s camera does not have the resolution to image these smaller storms, but this image suggests that the gas giant’s atmosphere is far far far more complex than we can yet imagine.

Full image of Jupiter reduced and annotated

Unfortunately, these images do not provide a scale. Based on a global image taken by Juno in October 2016 and matching the gas giant’s major horizontal bands, the annotated full image strip on the left appears to cover a little less than a third of Jupiter, from about 10 degrees latitude to about 50 degrees latitude. From this I estimate that if we put the Earth in the inset image it would probably be only slightly larger than the image itself, which means these two storms would cover most of one hemisphere.

In other words, the mini-storms inside the big bright oval are still larger than the biggest hurricanes on Earth, and they are packed together inside a much larger planet-sized storm.

What should fill us with even more awe is that this only covers a very thin slice of the top of Jupiter’s deep atmosphere. The planet itself is about 89,000 miles in diameter, more than ten times larger than Earth. The depth of its atmosphere is not really known, but it must be deeper than several Earths, piled on top of each other. In that depth there must be many atmospheric layers, each thicker and denser than the one above, and each with its own weather systems and complexities.

It will take centuries of research, including the development of new engineering capable of accessing this place, to even begin to map out its meteorology. And this is only one gas giant, of what we now know must be millions and millions throughout the galaxy.

If we have the nerve and daring, the human race has the opportunity to go out there and never be bored. There will always be something unknown to discover.

Another Grand Canyon tour

12:49 pm

On the Tonto Platform

Because I live in southern Arizona, I take advantage of this location to make an annual trip to the Grand Canyon. On my previous trips I’ve talked about the right way to hike the canyon (slowly!) and then provided some suggestions for proper preparation.

This time I am simply going to suggest two hikes. One is very easy and should be done by every visitor to the south rim. The other hike is for those who go to the bottom, and reserve themselves one day there for a day hike.

A tour of Vector Space Systems

4:31 pm

Jim Cantrell and cars

[UPDATE: I have been informed by Vector’s PR department that they have recently changed the company’s name, dropping “Space Systems” from the title. I can’t really change the title here, but I thought I note this fact for my readers.]

Today I got a quick tour of Vector Space System’s very blue collar but active rocket factory in Tucson, Arizona. My tour guide was Jim Cantrell, the CEO of the company.

Cantrell, shown on the right in front of one of his side businesses fixing and refurbishing race cars and rare luxury sports cars (also located in this factory), started out with a love of race cars, which he still builds and races. As he said to me, “Long endurance car racing is still my thing.”

However, he has also spent his life in the space business. He has worked for government agencies and numerous private businesses, including SpaceX at its very beginning. Vector Space Systems is an effort put together by him and several other people to capture the smallsat market, a market he truly believes is going to explode with activity in the coming years. If things go as he wishes, they hope to launch at least one hundred times a year, from multiple launch sites. Their goal is simplicity and quick turnaround at an inexpensive cost.

The company is presently in the testing phase leading up to their first orbital launches, which they hope to start in 2018. Right now they are building a series of full scale versions of their Vector-R rocket with a dummy second stage. The idea is to do a string of suborbital test flights, the first of which will fly in about a week from Mohave in California, with the second flying from the Georgia spaceport in Camden County. The image below is the first stage of that first test rocket.

Vector test first stage

Vector first stage engine

second test rocket

For this flight their main goal is to test the engine, which Cantrell is showing me in the picture to the right. I was astonished at how small and simple the engine was. In fact, the rocket itself was amazingly small. It looked like it could almost fit inside a typical moving truck.

Below and to the right is the first stage for their second test flight, presently being assembled. They hope it will be ready for flight in only a few weeks after the first flight. They plan five suborbital test flights, with the last capable of getting about 90% to orbit. Along the way they will test their avionics, the rocket’s balancing systems, and its computer and tanks. Once these tests are complete they will then move to testing the orbital version in 2018.

Obviously, all this depends on every test flight being successful. But then, even if something goes wrong they will learn something and move on. For example, they recently transported an engineering version of the rocket to the visitor center at Kennedy. As Cantrell explained, “We learned things new just making that move.”

bumper sticker

In the end, I think the bumper sticker to the right, attached to the window of Vector Space System’s office, sums everything up. The people at Vector want to make money in space, but they — like everyone in the space business — also love making rockets and engines and going fast. What better combination from life could you ask for?

Washington Bubble fights back against Capitalism in Space

12:06 pm

The response to my policy paper, Capitalism in Space, has been not surprisingly mixed. Eric Berger at Ars Technica wrote a reasonable analysis that focused on the absurdly high overhead costs of SLS/Orion. There have also been a number of critical reviews, one in Forbes and a second today in the print edition of Space News.

Both have tried to discredit the facts I have put forth about the ungodly cost of SLS/Orion, when compared to commercial space, without actually citing any incorrect facts in my paper. The truth is that everything I have written is true. This graph from my paper remains fundamental:

Table 5 from Capitalism in Space

SLS/Orion is costing four times as much, is taking more than twice as long to build, and is producing one tenth the operational flights. It is essentially a pork-laden jobs program that has no ability to get the United States anywhere in space. It might be an engineering marvel, but the cost is so high and its operational abilities so slow (one flight per year, at best) that it will never be a reliable and effective tool for exploring the solar system.

Meanwhile, private enterprise is getting innovative new rockets off the ground, for far less money, and repeatedly. If we want to settle the solar system, they are providing us the only viable way to do it.

People must recognize that these attacks are essentially the bubble of Washington working to protect its financial and intellectual interests. A lot of people in DC depend on keeping the faucet of government spending flowing to SLS/Orion, even if those projects accomplish nothing. In the case of the attacks from academics, they don’t like the fact that I am an outsider and not beholden to them. Moreover, they are instinctively appalled by the idea of allowing capitalism and freedom to operate freely, without their guiding hands controlling things. Such thoughts must be attacked and squelched (if possible), in order to protect their interests.

That they don’t seem to care that much about the interests of the American people and the country is quite revealing however. As some have said repeatedly, this is how you got Trump.

Capitalism in Space:
Private Enterprise and Competition Reshape the Global Aerospace Launch Industry

8:01 pm

After much delay and discussion, my policy paper for the Center for a New American Security, Capitalism in Space: Private Enterprise and Competition Reshape the Global Aerospace Launch Industry, has finally been published.

You can download the pdf here or at the Center here. Please feel free to distribute this widely. If you visit other websites please pass it on to them. This should be read by as many people as possible, especially since the space policy of the Trump administration remains at present undecided. This policy paper will help them work out a wise policy, with the paper’s key data point contained in this table:

SLS vs Commercial space

I document my numbers very carefully. The result illustrates clearly how much a failure the government model has been and continues to be. We have spent a lot of money since the 1970s on NASA and space, and have generally gotten very little for that investment, as demonstrated by the comparison between the accomplishments of private and government space in the past two decades. Going forward it is going to be very difficult for SLS/Orion to compete with the heavy lift rockets coming from SpaceX and Blue Origin.

My concluding words:

Trump budget proposal

11:24 am

The Trump administration today released its overall rough budget plan for 2018. This is not a detailed budget, but an summary of their plan, indicating where they wish to cut and where they wish to increase budgets. The proposal is also not complete, making no mention of the administration’s budget plans for many departments, such as the National Science Foundation.

Science research in the federal government is significantly impacted, but not as badly as most of the articles you will read in the mainstream anti-Trump, Democratic Party press. A few examples:

I must note that not all the news stories are blindly hostile to this budget proposal:

Of all the science agencies, NASA probably came off with the least change. The budget cuts only about 5% from the agency’s Earth science budget, while cutting some specific Earth science missions. The budget also supports SLS/Orion, though it finally puts the nail in the coffin of the asteroid redirect mission, an Obama proposal that has never garnered any interest from anyone else.

The Trump budget proposal in context

The key to understanding all these budget cuts is to see them in context, to compare the 2018 proposed budgets with the budgets these agencies received in the past. The table on the right gives some of this context (numbers shown are in millions) for several of the science agencies most effected by the proposal. The proposal is not detailed enough to pin down the changes for many other science agencies, but from this table it is clear that the Trump administration is not calling for the end of science, and is proposing some reasonable cost cutting, something that has been rare in government for many years.

What will be missed by most of the press about this Trump budget proposal is that it is not trying to trim the size of the federal government. While it cuts spending in many departments, those cuts are entirely aimed at providing room to raise the budget of the Defense Department by $54 billion. While I can applaud the desire of the Trump administration to be revenue neutral, the stark fact remains that by remaining revenue neutral Trump still leaves us with a gigantic annual federal deficit. They have made no effort to balance the overall budget.

Worse, this proposal would repeal the Budget Control Act of 2011, which imposed sequestration to the federal budget and has actually done the most in the past half century to bring that budget under control. Once this act is repealed, it will allow the spenders in Congress (of which the Republicans are as guilty as the Democrats) to open the floodgates once again. This will not be good.

Let me add one good aspect of the Trump budget. It proposes to eliminate a whole range of government political agencies that accomplish nothing but provide pork or to propagandize the Democratic Party’s positions:

The Budget also proposes to eliminate funding for other independent agencies, including: the African Development Foundation; the Appalachian Regional Commission; the Chemical Safety Board; the Corporation for National and Community Service; the Corporation for Public Broadcasting; the Delta Regional Authority; the Denali Commission; the Institute of Museum and Library Services; the Inter-American Foundation; the U.S. Trade and Development Agency; the Legal Services Corporation; the National Endowment for the Arts; the National Endowment for the Humanities; the Neighborhood Reinvestment Corporation; the Northern Border Regional Commission; the Overseas Private Investment Corporation; the United States Institute of Peace; the United States Interagency Council on Homelessness; and the Woodrow Wilson International Center for Scholars.

Getting these eliminated will at least be a start to cleaning up the mess in Washington.

At the crest

12:15 pm

Looking north at the crest

Cool images time! The image above, cropped and reduced to show here, is a panorama that I have created from the most recent images sent down from Opportunity yesterday. The rover sits on the crest of the rim of Endeavour Crater, and this panorama looks north at that crest, back in the direction where the rover has come. The rovers tracks can be seen fading away into the distance slightly to the left of the crestline..If you click on the picture you can see the full resolution image.

The crater floor is to the right, the plains that surround the crater are to the left.

Below is another panorama, created by me from the same images sent down today, this time looking south at the crest in the direction Opportunity is heading. Once again, if you click on the picture you can see the full resolution version.

The full set of today’s images from Opportunity suggest that the science team took them to assemble a full 360 degree panorama before they begin the journey south to the gully that is just now becoming visible at the southernmost edge of the most recent overhead traverse image. To get to that gully they will now have to descend off the crest and down outside the rim of Endeavour Crater, moving to the right in the panorama below. This is therefore their last opportunity for awhile to get a good view from a high overlook.

Cuts to NOAA, EPA, and the environmental bureaucracy

8:57 am

Two articles today outline some of the proposed cuts the Trump administration is considering for the EPA and NOAA and their generally bloated and politicized administrative bureaucracies.

The first article focuses on the proposed cuts to the EPA, which would reduce the overall budget to that agency by about 25%.

The Trump administration wants to cut spending by EPA’s Office of Research and Development (ORD) by more than 40% from roughly $510 million to $290 million, according to sources that have seen preliminary directives from the White House’s Office of Management and Budget (OMB). The cuts target scientific work in fields including climate change, air and water quality, and chemical safety. EPA’s $50 million external grant program for environmental scientists at universities would disappear altogether. Such erasures represent just part of a larger plan to shrink EPA’s budget by 25% to $6.1 billion, and cut its workforce by 20% to 12,400 employees, in the 2018 fiscal year that begins 1 October.

The second article focuses on proposed cuts aimed at NOAA and within the Commerce Department, with cuts in specific departments ranging from 5% to 26%, with an overall cut to NOAA of 17%.

The tampering of climate data at NOAA and NASA

11:35 am

data tampering at NASA

Last week there was the another Conservative Political Action Conference (CPAC) in Washington. One presentation there by several important climate skeptics outlined in detail the data tampering that has been going on at an increasingly outrageous manner at both NOAA and NASA in recent years. The slides presented by Tony Heller (available here [pdf]), many of which I have highlighted previously here at Behind the Black, are especially educational and damning.

To the right is just one of Heller’s slides, the one that I find the most damning of all. It shows how the surface data issued by NASA’s Goddard Institute of Space Studies (GISS), the two green lines, does not match the satellite data at all. While the satellite data shows no warming this entire century, the GISS data shows steady rising in the surface data. Other slides by Heller show that this rise comes solely from data adjustments and the extrapolation of imagined temperature data in places where no data exists, neither of which has been explained in any manner by the scientists at GISS.

What is most damning however is the change Heller documents between GISS’s November 2016 and December 2016 data sets. For reasons that are simply unjustified by any scientific measure, GISS somehow found it necessary to adjust its entire data set upward in one month about 0.03 of a degree. The only reason I can find for such a change in such a short period of time is a desire by the scientists at GISS to create the illusion that the climate is warming, and warming fast. They don’t have any real data to show this, so they make it up.

Make sure you look at all of Heller’s slides [pdf]. It is also definitely worthwhile to spend the time to watch the entire CPAC presentation, available at the first link above.

The consequences of leftwing censorship

11:27 am

Two stories today illustrate the consequences, both good and bad, of the left’s effort to stifle free speech on campuses:

The first story describes how a California law banning any university interaction with four states that have passed anti-transgender bathroom laws (laws that prevent men who are making believe they are women from entering women’s bathrooms) has prevented three California debate teams from attending the nationals.

This week the nation’s top debate coaches released their recognition of the top collegiate policy debate teams. This exceptional group of sixteen teams receives pre-bids to the National Debate Tournament at the end of March and will have strong potential toward winning the national title in debate at the tournament to be held at the University of Kansas in Lawrence. Two of the nation’s top teams that made this elite selection are from Berkeley, a campus recently racked by violent demands for the suppression of free speech. Incredibly, Berkeley’s teams and one other team from California who made the cut, will not attend the National Debate Tournament. That is because the state of California has banned all university related personnel from traveling to four states around the nation: Kansas, North Carolina, Tennessee, and Mississippi, on the specious grounds that these states have all passed “anti-LGBT legislation.” All debate teams from California state schools are practically banned from attending the national debate tournaments being held in the state of Kansas in March.

In other words, the intolerance by California to all alternative points of view has succeeded in literally shutting down all debate. As the author notes,

Killing both commercial space and American astronauts

9:54 am

This all reeks of politics: A new Government Accountability Office (GAO) report released yesterday says that NASA it should not permit Boeing and SpaceX to fly humans on their capsules and rockets until they fix certain issues and test both repeatedly on unmanned flights before the first manned flights to ISS.

This GAO report was mandated by Congress, and it requires NASA to certify that both Boeing and SpaceX have met NASA’s requirements before allowing those first manned flights. While the technical issues outlined in the report — to which NASA concurs — might be of concern, my overall impression in reading the report, combined with yesterday’s announcement by NASA that they are seriously considering flying humans on SLS’s first test flight, is that this process is actually designed to put obstacles in front of Boeing and SpaceX so as to slow their progress and allow SLS to launch first with humans aboard.

For example, the report lists three main problems with the commercial manned effort. First there is the Russian engine on the Atlas 5. From the report itself [pdf]:

Capitalism in Space to be released early next week

10:29 am

After several months of delay for a variety of reasons that I do not need to go into, my policy paper for the Center of New American Security has gone to the printers will be released to the public early next week. The title: Capitalism in Space: Private Enterprise and Competition Reshape the Global Aerospace Launch Industry.

I will have the pdf of this paper available here on Behind the Black the instant it is available. To give everyone a taste, here are my concluding words:

A close look at these recommendations will reveal one common thread. Each is focused on shifting power and regulatory authority away from the federal government and increasing the freedom of American companies to act as they see fit to meet the demands of the market. The key word that defines this common thread is freedom, a fundamental principle that has been aspired to since the nation’s founding. Political leaders from both parties have made the concept a central core tenet of American policy. Democrat John Kennedy stated that his commitment to go to the Moon was a “stand for freedom” in the Cold War. Republican Ronald Reagan proposed “Freedom” as the name for the new space station, and viewed it as a platform for promoting private enterprise in space.

Freedom is actually a very simple idea. Give people and companies the freedom to act, in a competitive environment that encourages intelligent and wise action, and they will respond intelligently and wisely.

The United States’ history proves that freedom can work. It is time that it prove it again, in space.
