UC-Berkeley blocks another conservative from speaking

10:14 am

Fascist Berkeley: UC-Berkeley this week told a conservative student group that another conservative speaker, author Ben Shapiro, could not speak on campus.

In a statement sent to the Washington Examiner on Wednesday evening, Young America’s Foundation announced that administrators informed the Berkeley College Republicans in an email this week they were “unable to identify an available campus venue” to host the lecture, which was slated for Sept. 14. The administrators, identified by YAF as Dean of Students Joseph Greenwell and Student Organization Coordinator Millicent Morris Chaney, claimed the lecture was spiked “despite extensive efforts.”

“Ben Shapiro is welcome on our campus, and we are committed to supporting his, and your, rights to free speech,” the administrators contended in their message to students, which was sent Tuesday.

I’m not sure which is more insulting, that university administrator are taking actions to prevent conservative and dissent views from appearing on their campus, or that they have the nerve to insult our intelligence by claiming “Shapiro is welcome on our campus.”

Once again I ask: Would you want to attend this university? Would you want your kids to go there? And why on Earth would anyone support it with donations?

Hundreds of NASA videos uploaded to Youtube

10:00 am

Want to look at some old but cool NASA engineering videos? You can! The Armstrong Flight Research Center (formerly Dryden) has uploaded a large number to Youtube.

Below the fold is one example, a tow test of one of the early lifting body spacecraft, the M2-F1, a prototype of the kind of spacecraft Dream Chaser is trying to be. What makes the video most interesting is the vehicle used to do the towing, a Pontiac Catalina convertible, and that it actually pulls it fast enough for the spacecraft to lift off the ground.

News from SpaceX

10:18 pm

Capitalism in space: At the annual convention of the National Space Society, Elon Musk revealed some significant new details about his company’s future engineering and launch plans.

The first two stories are related, as it had been powered landings that SpaceX hoped to use for its Red Dragon Mars landings. Dropping powered landings, at this time, means that the first Dragon mission to Mars will likely not happen in 2020. While Musk outlined a number of good engineering reasons for this decision, to me this quote from the first article was significant:

SpaceX planned to transition from splashdowns, which is how the current cargo version of the Dragon returns to Earth, to “propulsive” landings at a pad at some point after the vehicle’s introduction. Certification issues, he said, for propulsive landings led him to cancel those plans. “It would have taken a tremendous amount of effort to qualify that for safety, particularly for crew transport,” he said.

In other words, NASA was balking at this innovation, and was putting up so many obstacles that it just wasn’t worth the company’s effort at this time. NASA is their main customer for manned launches, and NASA doesn’t like daring or creativity or innovation. The powered version of Dragon will probably have to wait for other private customers looking for a way to get into space.

The third story outlines the engineering challenges that SpaceX has been dealing with in its effort to build the Falcon Heavy, and includes this tidbit from Musk:

With all of these elements in consideration, Mr. Musk is urging caution regarding public expectation for Falcon Heavy’s first flight, saying that there is a “real good chance that the first vehicle [won’t] make it to orbit. So I want to make sure to set expectations accordingly.”

Even more telling was how Musk continued on this point, stating that he hoped Falcon Heavy makes it far enough away from LC-39A before failing so the pad will escape significant damage. “I hope it makes it far enough away from the pad that it’s not going to cause damage. I would consider that a win, honestly,” said Mr. Musk.

Thank God NASA is not involved in the development of the Falcon Heavy. SpaceX would have probably had to abandon this as well.

Meanwhile, this detailed article by Eric Berger gives us Elon Musk’s position on NASA’s contracting system. Not surprisingly, much of what Musk says mirrors what I wrote in Capitalism in Space:

During his remarks Saturday, Musk said NASA could avoid unnecessary delays and costs by transitioning to a system of competitive awards for fixed-price contracts, in which companies are only paid when they meet “milestones” such as completing a flight test or satisfying NASA about the safety performance of a vehicle. Additionally, he said, at least two entities should compete during the development process.

There’s a lot more there, and it is worth a full reading.

Has India cut its cubesat launch prices?

9:45 pm

Capitalism in space: A complex analysis of India’s recent launch prices suggests that ISRO reduced its cubesat launch prices when it launched a record-setting 103 satellites on the most recent PSLV launch.

The key paragraph however is this:

Small-satellite owners have long complained that the PSLV, whose reliability has been established in the market, has been slow to increase its launch tempo at a time of surging cubesat production. For the moment, none of these satellite customers’ launch options provide predictable launch cadence at affordable prices.

That may be about to change as several dozen vehicles designed specifically to accommodate the growing cubesat market are preparing to enter operations. Not all are likely to succeed in establishing a foothold, but the sheer number of them is impressive:

That makes it all the more important for ISRO’s Antrix Corp., the agency’s commercial arm, to cement a reputation for launch regularity and low prices.

In other words, because a flock of new smallsat launch companies, such as Rocket Lab, Vector, and Virgin Orbit, are about to enter the market ISRO is suddenly feeling the pressure, which is why they have cut prices as well as started to up their launch rate.

Isn’t competition wonderful?

Sierra Nevada picks ULA’s Atlas 5 for first two Dream Chaser cargo flights

9:38 pm

Capitalism in space: Sierra Nevada has awarded ULA the contract for the first two cargo flights of Dream Chaser to ISS.

The announcement sets Dream Chaser’s first cargo flight to the International Space Station for launch from Cape Canaveral Air Force Station, Florida, in 2020. A second ISS cargo flight is contracted to lift off the next year. “ULA is an important player in the market and we appreciate their history and continued contributions to space flights and are pleased to support the aerospace community in Colorado and Alabama,” said Mark Sirangelo, corporate vice president of SNC’s Space Systems.

Financial terms of the contract were not disclosed.

LISA Pathfinder switched off

8:17 am

After a successful mission proving the technology for a full scale orbiting gravitational wave detector, LISA Pathfinder was shut off yesterday.

After 16 months of science measurements an international team deactivated the LISA Pathfinder satellite on the evening of the 18th of July 2017. The gravitational-wave laboratory in space powered down after receiving the last commands in the evening and circles the Sun on a safe parking orbit. LISA Pathfinder has tested key technologies for LISA, the future gravitational-wave observatory in space, and has demonstrated their operative readiness. LISA is scheduled to launch into space in 2034 as an ESA mission and will “listen” to the entire Universe by measuring low-frequency gravitational waves.

The idea is laudable, but for Europe to need another seventeen years to build and launch the full scale telescope is absurd. They now know what needs to be done. It should be relatively easy and quick to get it into orbit. And even if it isn’t easy, seventeen more years? Give me a break.

SpaceX competitors team up to try to block its satellite constellation

10:06 am

SpaceX’s main competitors in creating a satellite broadband industry have all filed objections with the FCC to the company’s planned 4,425 satellite constellation that is aimed at providing worldwide internet access.

SpaceX’s plan to provide global broadband internet access using thousands of satellites in low-earth orbit has come under fire from competitors, including Boeing and OneWeb, according to Space Intel Report. The argument is playing out in a series of filings with the Federal Communications Commission, focusing on SpaceX’s request for a temporary waiver from the FCC’s time limits for putting the satellite system into full operation.

The FCC would typically require the system to provide full coverage of U.S. territory within six years of a license being issued, but SpaceX says that’s not enough time to deploy the full 4,425-satellite constellation. Instead, the company proposes launching the first 1,600 satellites in six years, which would leave the northernmost part of Alaska without coverage when the deadline hits. Full U.S. coverage would be provided after the six-year deadline, SpaceX says.

In their own filings, competitors including OneWeb, SES/O3b and Intelsat are urging the FCC not to waive the six-year requirement, Space Intel Report said.

This is garbage, and demonstrates again why it is dangerous to give government too much power. Rather than compete by launching their own satellite constellations first, these companies want the FCC to put its finger on the scale to favor them and stop SpaceX. And I bet the decision will be made based not on what is right but on who gave the most campaign contributions to the right political party.

New adjustments to early satellite data confirm accelerating sea level rise

9:50 am

Well la-de-da! Surprise, surprise! New adjustments made by climate scientists to early satellite sea level data confirm an accelerating sea level rise.

The numbers didn’t add up. Even as Earth grew warmer and glaciers and ice sheets thawed, decades of satellite data seemed to show that the rate of sea-level rise was holding steady — or even declining.

Now, after puzzling over this discrepancy for years, scientists have identified its source: a problem with the calibration of a sensor on the first of several satellites launched to measure the height of the sea surface using radar. Adjusting the data to remove that error suggests that sea levels are indeed rising at faster rates each year. “The rate of sea-level rise is increasing, and that increase is basically what we expected,” says Steven Nerem, a remote-sensing expert at the University of Colorado Boulder who is leading the reanalysis. He presented the as-yet-unpublished analysis on 13 July in New York City at a conference sponsored by the World Climate Research Programme and the International Oceanographic Commission, among others.

Nerem’s team calculated that the rate of sea-level rise increased from around 1.8 millimetres per year in 1993 to roughly 3.9 millimetres per year today as a result of global warming. [emphasis mine]

This data correction might be true, but the highlighted phrases from this Nature article reveals two reasons why I do not trust these changes. First, there is the fact that this research and its adjustments to past data have not been published nor reviewed by anyone other than the people who agree with them. Second is the bald-faced completely impossible claim made that the sea level rise is caused by global warming. This work itself cannot possible determine what caused the sea level rise, as it is only observational, attempting to measure the rise, not study the cause. To make such a claim in this context is inappropriate.

Finally, it is this quote that makes me even more suspicious that this is garbage:

“As records get longer, questions come up,” says Gavin Schmidt, a climate scientist who heads NASA’s Goddard Institute for Space Studies in New York City. But the recent spate of studies suggests that scientists have homed in on an answer, he says. “It’s all coming together.”

Gavin Schmidt is the king of data tampering, constantly fiddling with the old climate data controlled by his institute so that it always cools the past and warms the present, thus increasing global warming not by actual observational data but by his personal whim. As this recent peer-reviewed review of Schmidt’s tampering noted, “The conclusive findings of this research are that the three GAST data sets are not a valid representation of reality.”

The sooner these fake scientists can be removed from positions of power over the datasets climate scientists need and use, the better.

Claremont McKenna College suspends students who led violent protest

10:54 pm

This is a victory. Claremont McKenna College has issued suspensions to seven students for their violent actions that threatened a pro-police speaker and anyone who wished to hear her lecture.

After reviewing video and photos of the blockade, the college has punished seven students: Three received one-year suspensions, two received one-semester suspensions, and two were put on conduct probation, the college’s announcement said. Officials also issued provisional suspensions of on-campus privileges to four non-students who appear to have played significant roles in the blockade, according to the statement.

“On the evening of April 6, a group of approximately 170 individuals from the Claremont Colleges and others outside our community organized, led, and executed a blockade of the Athenaeum and the Kravis Center. They breached the perimeter safety and security fence and campus safety line, and established human barriers to entrances and exits. These actions deprived many of the opportunity to gather, hear the speaker, and engage with questions and comments,” according to the statement. “… Sanctions were based on the nature and degree of leadership in the blockade, the acknowledgment and acceptance of responsibility, and other factors.”

This is also only a first step. As noted by the speaker, it is puzzling that with all the videotape records available, only 11 out of 170 individuals were identified for punishment.

Republican health tweak of Obamacare dead, Senate to vote for straight repeal

10:35 pm

This is a victory: The Republican leadership in the Senate, lacking the votes to pass their own version of Obamacare, have decided to instead go for full repeal.

Senate Majority Leader Mitch McConnell bowed to pressure tonight from conservatives — and President Trump — to bring up a straight repeal of most of the Affordable Care Act as the next step now that the Senate health care bill appears to be dead. It will be based on the repeal bill Congress passed in 2015, which then-President Barack Obama vetoed.

His statement: “Regretfully, it is now apparent that the effort to repeal and immediately replace the failure of Obamacare will not be successful. So, in the coming days, the Senate will vote to take up … a repeal of Obamacare with a two-year delay to provide for a stable transition period to a patient-centered health care system that gives Americans access to quality, affordable health care.”

McConnell’s hand was forced when two conservative senators, Mike Lee (R-Utah) and Jerry Moran (R-Kansas) announced earlier today that they would not vote for the bill.

This is what they should have done from the beginning. Granted, it is likely to fail because of Democratic opposition, but then it will be clear going into the next election who is standing in the way of fixing the problem. Had they passed any version of their turkey of a bill, the health insurance business would have continued to fail, but they would no longer have had clean hands. It would have become their problem, and it would have cost them votes in 2018.

Now, things will be clean, and we will get to see who really is on our side, from both parties. Expect several Republican senators especially to suddenly “evolve” and decide that they can’t go along with the very repeal they’ve voted for repeatedly in the past, because it might “hurt people.”

A map of Pluto

9:11 pm

Our best map of Pluto for many decades to come

The New Horizons science team has released the best maps of both Pluto and Charon possible from the images taken during the spacecraft’s fly-by of the ninth planet last year.

The new maps include global mosaics of Pluto and Charon, assembled from nearly all of the highest-resolution images obtained by New Horizons’ Long-Range Reconnaissance Imager (LORRI) and the Multispectral Visible Imaging Camera (MVIC). These mosaics are the most detailed and comprehensive global views yet of the Pluto and Charon surfaces using New Horizons data.

The new collection also includes topography maps of the hemispheres of Pluto and Charon visible to New Horizons during the spacecraft’s closest approach. The topography is derived from digital stereo-image mapping tools that measure the parallax – or the difference in the apparent relative positions – of features on the surface obtained at different viewing angles during the encounter. Scientists use these parallax displacements of high and low terrain to estimate landform heights.

You will also notice large areas of both Pluto and Charon that remain very fuzzy and unclear. What exactly is there will remain a mystery for many decades to come.

Dream Chaser test vehicle undergoing tow tests

8:58 pm

Capitalism in space: Sierra Nevada’s Dream Chaser engineering test vehicle underwent tow tests today.

Rolling on two main landing gear wheels and a nose skid, the Dream Chaser traveled down a runway Monday in Sierra Nevada’s latest tow test at Edwards Air Force Base, which is co-located with NASA’s Armstrong Flight Research Center. Once cut free from its tow vehicle, the Dream Chaser slowed to a stop, allowing engineers to gather data on the craft’s brakes, steering system, and guidance, navigation and control sensors that will line the spaceplane up for landing, according to Eric Cain, a Sierra Nevada engineer who described Monday’s test on the company’s Twitter account.

More tests are planned in the coming months, including additional tow tests and a “captive carry” flight with the Dream Chaser suspended under a helicopter.

This is the same engineering test vehicle that underwent tow tests and flew successfully once, though its landing gear failed up upon touchdown. They have replaced that landing gear, which was borrowed from the Air Force and was never intended to be the spacecraft’s wheels. Thus, they need to go through these tests all over.

Trump administration to increase use of asset forfeiture

2:44 pm

Theft by government: Attorney General Jeff Sessions today told a gathering of district attorneys that the Trump administration intends to increase the use of asset forfeiture, the procedure where the government steals private property merely because it suspects it might have been related to a criminal act, even if the owners are completely innocent.

Although the details have yet to be released, Sessions’ directive appears likely to loosen the restrictions on “adoptions” of forfeiture cases by the federal government—an alarming prospect for opponents of asset forfeiture. “Reversing the ban on adoptive seizures would revive one of the most notorious forms of forfeiture abuse,” Sheth said. “So-called ‘adoptive’ seizures allow state and local law enforcement to circumvent state-law limitations on civil forfeiture by seizing property and then transferring it to federal prosecutors for forfeiture under federal law. Bringing back adoptive seizures would create a road map to circumvent state-level forfeiture reforms.”

Sessions’ upcoming directive to increase asset forfeiture comes as little surprise. Sessions, a former prosecutor and U.S. senator, has been a stalwart defender of asset forfeiture throughout his career. He has already dismantled Obama-era directives on drug sentencing guidelines and ordered a review of all of the existing consent agreements between the Justice Department and police departments that were found to be violating residents’ constitutional rights.

This is only more evidence that both parties in Washington are corrupt power-grabbers who don’t give a damn about the Constitution and the real rule of law. Sessions might be good in some areas, but in others he is as bad as Eric Holder.

NASA communications satellite damaged during launch prep

8:20 am

A NASA TDRS communications satellite, scheduled for a August 3 launch on a ULA Atlas 5 rocket, was damaged on July 14 while it was undergoing final preparations for launch.

Though the issue apparently involves one of the satellite’s main antennas, it is unclear what happened exactly or how extensive the damage was. Furthermore, this article about the incident notes that an earlier incident had also occurred during shipping.

It is understood this latest incident is not related to a ‘close call’ that NASA was investigating earlier in the flow. That incident involved the spacecraft’s shipping container – containing environmental instrumentation – which slid a couple of feet on the trailer it was being winched on to.

If I was a customer who might want to buy the launch services of ULA, I would demand detailed information about why these incidents happened, including what measures are being taken to prevent them from occurring again.

White House appoints first member of National Space Council

11:03 am

The Trump administration today announced that Scott Pace will be the executive secretary of the National Space Council, headed by Vice-President Mike Pence.

Some might immediately think I will be upset by this choice, as Pace wrote a critical and what I consider to be a weak review of my policy paper, Capitalism in Space. This however is not true. We might have disagreed on some points, but I think that Pace might be an ideal choice. He has the ear and the support of the big government space companies, but also understands the need to let private enterprise run things more, a point he himself expressed in his review of my policy paper. As Dr. David Livingston of The Space Show wrote me today in an email,

Pace was the deputy administrator when Mike Griffin formed COTS which has turned out to be a pillar program for the emerging commercial space industry. I also know Scott is grounded well in economics, policy, and realism. He is politically savvy as well and that expertise will be needed to move policy and constructive programs forward.

Pace’s connections with the contractors who have been building SLS/Orion for decades are of course a concern, but his connections with COTS is cause for celebration. We can only wait and see where this goes.

House appropriations approves NASA and NOAA budgets

10:12 am

The squealing of pigs: The House appropriations committee yesterday approved the budgets for both NASA and NOAA, essentially accepting the budget numbers approved by its subcommittee.

Overall, the House increased spending over the Trump administration’s proposed cuts. Only in the area of climate did the legislators appear to support those cuts, and even here they pumped more money in.

The Trump Administration proposed a deep cut to [NOAA’s Polar Follow-On mission] saying it will re-plan the program ($180 million instead of the $586 million NOAA said last year it would need for FY2018). The committee went even further, approving only $50 million, but added it would reconsider if NOAA provides a better explanation of how it is restructuring the program. NOAA’s plans for new space weather satellites also fell far short of what the agency planned last year, although the committee provided more ($8.5 million) than the Trump Administration requested ($500,000).

In general, do not expect this Republican Congress to gain any control over the federal deficit. They are as spendthrift as Democrats. The only difference is their choice of programs.

Luxembourg parliament adopts draft space law

9:57 am

Capitalism in space: The Luxembourg parliament yesterday adopted a draft space law that will allow that country to authorize, under the Outer Space Treaty, future private enterprise missions in space, including mining on the Moon and the asteroids.

The press release makes the following claim:

The Grand Duchy is thus the first European country to offer a legal framework ensuring that private operators can be confident about their rights on resources they extract in space. The law will come into force on August 1, 2017. Its first article provides that space resources are capable of being owned. The country’s law also establishes the procedures for authorizing and supervising space exploration missions.

In reading the actual law [pdf], however, I do not think this really does what they claim. All the law does is simply state that “Space resources are capable of being appropriated.” That’s it. They are essentially saying that any private profit-oriented mission that launches under Luxembourg’s authorization will have their blessing to take as much from any planetary body as they desire. No property rights are delineated, including the borders of any territory owned, which is not surprising since the Outer Space Treaty forbids Luxembourg from doing so.

In fact, I think this illustrates for us all the future as we colonize the solar system, assuming the Outer Space Treaty is not revised or dumped. Like pirates, nations (or their citizens) will grab as much as they can, and will then use force to protect those holdings from any one else. Everyone will have to do this, because there will be no legal framework to establish their claims.

Since it appears, at least for the present, that no one wants to change the Outer Space Treaty, expect the future in space to be a brutal legal nightmare for all involved.

First Starliner manned flight delayed to late 2018

9:24 pm

Boeing has revealed that the first manned flight of its commercial Starliner capsule will likely be delayed a few more months to late 2018.

The latest confirmed schedules from NASA show the uncrewed mission, dubbed the Orbital Flight Test (OFT), slated for No Earlier Than June 2018, followed quickly in August 2018 by the crewed flight test.

However, comments made by Chris Ferguson last month at the Paris Air Show seem to indicate that the crewed flight test is moving from its August timeframe. According to Mr. Ferguson, Director of Crew and Mission Operations for Boeing’s Commercial Crew Program, the first Starliner crewed test flight is aiming for “last quarter of 2018” – which would be a shift of two to five months into the October to December 2018 timeframe.

The unmanned test flight, however, remains set for a June 18, 2018 launch.
