China successfully launches two satellites

8:43 am

China’s Long March 4C rocket successfully placed two satellites in orbit today, a weather satellite and a commercial data relay satellite.

This was China’s 11th launch in 2017, well below the 20 they achieved in 2016, the drop caused by two launch failures earlier this year that resulted in an almost four month pause in launches.

At present the race for the most launches in 2017 stands as follows:

17 Russia
16 SpaceX
11 China
10 Arianespace (Europe)
7 ULA
5 Japan
4 India
3 Orbital ATK

Overall, the United States leads with 26 launches, its most since 2000.

Zwicky Transient Facility sees first light

10:54 am

Astronomers announced today that the Zwicky Transient Facility at the Palomar Observatory in California has seen first light, and will begin full operations in 2018.

When fully operational in 2018, the ZTF will scan almost the entire northern sky every night. Based at the Palomar Observatory in southern California and operated by Caltech, the ZTF’s goal is to use these nightly images to identify “transient” objects that vary between observations — identifying events ranging from supernovae millions of light years away to near-Earth asteroids.
an image of stars and the night sky

In 2016, the UW Department of Astronomy formally joined the ZTF team and will help develop new methods to identify the most “interesting” of the millions of changes in the sky — including new objects — that the ZTF will detect each night and alert scientists. That way, these high-priority transient objects can be followed up in detail by larger telescopes, including the UW’s share of the Apache Point Observatory 3.5-meter telescope.

By producing new high resolution images of the entire northern sky every night, this telescope instrument is going to discover gobs of new transients, from supernovae to binaries to novae to things we haven’t even seen before.

Japan to make second launch attempt of world’s smallest orbital rocket

9:44 am

JAXA, Japan’s space agency, has announced that it will make a second launch attempt in December of what would be the world’s smallest orbital rocket.

The rocket, measuring 10 meters long and 50 cm in diameter, will carry a “micro-mini” satellite weighing about 3 kg developed by the University of Tokyo to collect imagery of the Earth’s surface.

The launch scheduled for Dec. 25 will feature the fifth rocket in the SS-520 series. The Japan Aerospace Exploration Agency (JAXA) is hoping small rockets made with commercially available components at low cost will help fuel the growing global demand for micro-mini satellites. JAXA used components found in home electronics and smartphones for the rocket, which is about the size of a utility pole.

The previous launch failed when vibrations during liftoff caused a short-circuit that cut off communications, forcing them to terminate the flight.

Billionaire Yuri Milner considering funding mission to Enceladus

9:21 pm

Capitalism in space: Billionaire Yuri Milner, who already funds several astronomy projects aimed at interstellar travel, is now considering funding a planetary probe to the Saturn moon Enceladus.

At the moment all he is doing is holding workshops with scientists and engineers to see if such a mission can be done for an amount he can afford. Considering that Elon Musk’s first concept to send a private probe to Mars, before SpaceX existed, was stopped because of high launch costs, thus becoming the inspiration for SpaceX itself in order to lower those costs, Milner’s private effort might actually be affordable now.

Sacrificing Scientific Skepticism

10:59 am

Phil Berardelli, who periodically comments here and who is a veteran science journalist who worked for the journal Science for a number of years, has written a very cogent four part essay on the subject of climate change for the think tank Capital Research Center.

Berardelli very carefully outlines the uncertainties that dominate our knowledge of the Earth’s climate, while explaining clearly why consensus is never what good science relies upon. As he notes,

Science is not primarily about proof; science is about disproof. Nothing in science, absolutely nothing, should ever be taken at face value. This view isn’t new; it’s age old.

Read it all, especially if you are one of the people who reads my writing and questions my skepticism about much of what I see in the climate field, especially coming from NASA and NOAA. Berardelli illustrates how doubt and skepticism are the hallmarks of science, and should always be honored, not denigrated with slurs like “denier.”

Full disclosure: Phil Berardelli was also my editor when I did a weekly column for UPI called Space Watch for six months in 2005.

Next Dragon launch for NASA may fly using reused first stage

9:19 am

Capitalism in space: NASA revealed today that it is close to approving the use of a Falcon 9 reused first stage for the next Dragon cargo mission to ISS.

During a press conference at NASA’s Wallops Flight Facility here Nov. 10 about the launch of a Cygnus cargo mission to the ISS, a NASA manager said the agency would likely approve the use of a reused booster on that mission, designated SpX-13, assuming it clears an upcoming review. “We’re in the final stages of doing all those assessments,” Dan Hartman, ISS deputy program manager, said. SpaceX first requested to use a previously-flown booster for a cargo mission about a year ago. “On the NASA side, we’ve had a lot of major reviews.”

He said SpaceX itself had one more readiness review for the booster they’re planning to refly before deciding if they can use it for the SpX-13 mission, scheduled for launch Dec. 4. “If that comes back positive,” he said, “I’d say the chances are that we’ll be flying a reuse on SpX-13.”

It appears that about a year from now the use of reused boosters will have become completely normalized, with no one thinking anything unusual about their use. This, after almost a half century of old-school engineers and managers repeatedly saying such a thing made no sense and was impossible in terms of engineering and economics.

Dream Chaser test vehicle flies again!

9:12 am

Capitalism in space: Sierra Nevada’s Dream Chaser test vehicle today completed its second glide test, the first since 2013, successfully gliding to a perfect landing after being dropped from a helicopter at an altitude of 10,000 feet.

Unlike the 2013 glide test, the landing gear worked perfectly. With two such tests under their belt, the company I think has demonstrated that the spacecraft will be able to execute a landing. Next comes the building and test flight of the actual spacecraft.

Saudi Arabia has launched a military strike against Yemen

3:28 pm

Saudi Arabia has launched a military strike against Yemen’s defense ministry.

It wasn’t immediately clear if the attacks were air or missile strikes, but they came following reports that Iran had manufactured the ballistic missile fired by Yemen’s Shiite rebels toward the Saudi capital a week ago.

Remnants of the missile bore “Iranian markings,” the top US Air Force official in the Mideast said Friday, backing the kingdom’s earlier allegations.

This isn’t that much of a surprise, considering the recent purge in Saudi Arabia as well as the recent reports of both Saudi Arabia and Kuwait warning their citizens to leave Lebanon. The military strike today in Yemen appears to therefore merely be a precursor of a more significant escalation.

A storm on Jupiter

10:09 am

A storm of Jupiter

Cool image time! The image above, reduced in resolution to post here, was taken during Juno’s ninth close fly-by of Jupiter in late October, and shows one particular storm swirl in the gas giant’s southern hemisphere.

The Juno team today highlighted an image taken during this fly-by of Jupiter’s entire southern hemisphere, but I find this close-up more interesting. Be sure to check out the full resolution version. It appears to me that the white swirls have risen up above the gold and blue regions, casting shadows down upon them.

Unfortunately, I cannot tell you the scale of this storm, as the release does not give any details, including where in the full hemisphere image it is located. I suspect, however, that it is large enough to likely cover the Earth.

Both the full hemisphere image and the image above were processed by citizen scientists Gerald Eichstädt and Seán Doran.

Physicists shrink their next big accelerator

9:52 am

Because of high costs and a refocus in research goals, physicists have reduced the size of their proposed next big particle accelerator, which they hope will be built in Japan.

On 7 November, the International Committee for Future Accelerators (ICFA), which oversees work on the ILC, endorsed halving the machine’s planned energy from 500 to 250 gigaelectronvolts (GeV), and shortening its proposed 33.5-kilometre-long tunnel by as much as 13 kilometres. The scaled-down version would have to forego some of its planned research such as studies of the ‘top’ flavour of quark, which is produced only at higher energies.

Instead, the collider would focus on studying the particle that endows all others with mass — the Higgs boson, which was detected in 2012 by the Large Hadron Collider (LHC) at CERN, Europe’s particle-physics lab near Geneva, Switzerland.

Part of the reason for these changes is that the Large Hadron Collider has not discovered any new particles, other than the Higgs Boson. The cost to discover any remaining theorized particles was judged as simply too high. Better to focus on studying the Higgs Boson itself.

United Arab Emirates signs space agreement with Germany

9:43 am

The new colonial movement: The United Arab Emirates (UAE) has signed a memorandum of understanding with the German Aerospace Center.

The press release doesn’t say much, other than the agreement will facilitate the exchange of information. Since the UAE can contribute little here but money, and none appears to be offered, I am curious as to exactly what is involved. It could be that Germany is looking at this as a form of inexpensive foreign aid, providing help to the UAE’s nascent space effort in order to establish good will and good relations.

Update on the development of Blue Origin’s orbital rocket New Glenn

9:36 am

Link here. The article provides a lot of interesting details about Blue Origin’s plans and status, including this tidbit about the New Glenn assembly facility, now expected to be finished by February 2018 at the latest:

The facility will largely be used to build the second and third stages for New Glenn, with Blue Origin actually planning to construct very few first stage boosters.

With each first stage booster planned to be reused up to 100 times, the factory will mainly concentrate on – and for large periods of time is only planned to – produce 2nd and 3rd stages. Mr. Henderson noted that once the first stage boosters are retrieved after flight, their storage will be managed across the refurbishment facility at LC-36 (capable of holding three or four boosters), the integration facility at LC-36 (also capable of holding “at least” three or four boosters), and the Merritt Island production facility (which can hold four boosters).

This would seemingly reveal that Blue Origin plans to rely on roughly only 12 first stage boosters at a time (once New Glenn is fully operational and recovery is “routine”), relying almost exclusively on booster recovery and refurbishment to maintain its first stage boosters manifest.

The article also notes the Blue Origin intends to always land its stages on a barge, and is about to finalize the purchase of that barge.

What I am puzzled about is the almost complete disappearance from the news of the company’s suborbital project, New Shepard. The last news story I’ve seen, from mid-September, said they hoped to resume test flights before the end of the year, with manned flights in 2018. Since then, however, there has been no updates, which makes me wonder if Blue Origin has decided to put that suborbital tourism project aside.

Crowdfunding campaign to honor only cat to fly in space

9:27 am

A crowdfunding campaign has been started to build a 5-foot-tall bronze statue in honor of Félicette, the only cat to fly in space.

While the first dog in space, Laika, has a statue, and the first chimp, Ham, has a memorial, Félicette has close to nothing. There are some commemorative stamps honoring a mythical space cat “Felix.” But Felix’s portrait doesn’t look like Félicette and it has a male name, so this is not enough for Guy. If anything, he says, the stamps simply help erase the existence of female astronauts.

The French space program gathered 14 cats, implanted electrodes into their brains, and put them through training similar to the way that they train human astronauts. They ultimately chose Félicette to make the trip, either because of her docile personality, or because she had not put on too much weight, according to differing accounts.

She was launched into space from Algeria [in 1963], and made it nearly 100 miles above Earth. For five minutes, she was weightless. Félicette came back to Earth unharmed, parachuting down and being retrieved only 13 minutes after having left her home planet. She stayed at the program’s lab for two to three months, according to Guy, but scientists later killed her to study the effects of space travel on her body.

Seems to me to be the right thing to do.

Washington swamp creature hints that SLS could be in trouble

5:04 pm

Congressman Lamar Smith (R-Texas) today expressed strong disappointment with the repeated delays in the the launch of SLS and Orion, noting that the problems could lead to Congress considering “other options.”

“After all these years, after billions of dollars spent, we are facing more delays and cost overruns,” Smith said. While he noted that some delays were caused by factors out of NASA’s control, like a tornado that damaged the Michoud Assembly Facility in New Orleans in February, “many of the problems are self-inflicted.”

“It is very disappointing to hear about delays caused by poor execution, when the U.S. taxpayer has invested so much in these programs,” he added.

Smith, who announced Nov. 2 he would not run for reelection next year after more than three decades in the House, including serving as chairman of the science committee since 2013, warned about eroding support for the programs should there be additional delays. “NASA and the contractors should not assume future delays and cost overruns will have no consequences,” he said. “If delays continue, if costs rise, and if foreseeable technical challenges arise, no one should assume the U.S. taxpayers or their representatives will tolerate this forever.”

“The more setbacks SLS and Orion face, the more support builds for other options,” he said, not elaborating on what those options would be.

Smith is part of the establishment in Congress that has been supporting SLS and Orion blindly for years. Unfortunately, he is retiring this year, and the other members of his committee did not seem as bothered by SLS’s endless delays.

This week in fascist academia

3:24 pm

This week’s collection of stories illustrating the fascist culture that permeates today’s academic community actually includes some good news. (My last fascist academia post can be seen here.)

First the bad:

The first story illustrates that this intolerance is not limited to the left. In this case a conservative university kicked out a speaker with more moderate views.

Nonetheless, the majority of these attacks on freedom of speech continue to come from the left or from left-leaning organizations. The last story indicates the trends, which include a significant shift towards violence and a disrespect for property rights.

Now for the good news.

In the first story we see a rare example of someone experiencing bad consequences for their bad fascist behavior. If only this would happen more often. In the second story the theatrical community, including the normally very leftwing partisan Dramatists Guild of America (!), has actually come out against censorship, even if that censorship involves opinions that attack modern liberal sacred cows, such as the racist Black Lives Matter movement. This action is so out of the norm that I am somewhat speechless.

Tuesday’s election results

10:47 am

The election results from Tuesday, where Democrats won most of the significant races, has produced a lot of commentary, from both conservatives and liberals, about its significance.

To me, however, these results merely confirmed the increasingly regional nature of today’s partisan politics. This story, about a victory by a Democrat state senator candidate that puts the Democrats in complete control of Washington’s legislature, illustrates this best.

Dhingra’s victory in Washington state over Republican Jinyoung Englund means the West Coast is now the solid center of the resistance, with Democrats controlling legislatures and governorships from Seattle down to San Diego.

The Democratic victories on Tuesday all took place in areas where they strongly dominate (the coasts and urban centers), thus merely solidifying their control over those localized regions. I expect that future elections will show Republicans solidifying their control over their own regions (which is the rest of the country). In other words, people are beginning to choose sides, and we are heading to a regional and political divide that can only be solved in one of two ways: The U.S. splits, or a civil war (in the literal sense) breaks out.

A simple and inexpensive skin cancer detector wins award

10:10 am

A simple and inexpensive skin cancer detector has won the $40,000 2017 James Dyson award.

Designed by a team from McMaster University in Canada, the sKan can make more accurate diagnoses quickly and reasonably cheaply. It’s based around the fact that cancer cells have a faster metabolic rate than healthy cells, meaning they release more heat. To check if a patch of skin has the beginnings of a melanoma, the suspected area is first cooled with an ice pack before the sKan device is placed against the skin.

Using an array of temperature sensors called thermistors, the sKan will then monitor the area as the skin warms back up. If there’s a melanoma present, it will warm up faster than the surrounding skin, revealing itself on a heat map and temperature difference time plot created through a connected computer program.

Once this device is in the hands of dermatologists, they will be able to very quickly diagnose whether a skin mole or freckle is dangerous or not.

India’s space agency ISRO hopes to double launch rate

10:02 am

Capitalism in space: ISRO officials said yesterday that the agency plans to double its launch rate next year, while also shifting as much of its space manufacturing effort to the private sector.

Currently, the space agency launches 9 to 10 spacecraft built by it every year. Dr K Sivan, director of Thiruvananthapuram-based Vikram Sarabhai Space Centre, said, “Isro is targeting to double the number of launches from 9-10 to 18-19 launches per year.”

On outsourcing of jobs to the private industry, Isro chairman A S Kiran Kumar said the space agency does as much activity as possible with the industry. “Wherever it’s possible to get things done through the industry, we are doing and it will only increase in the coming days because we need to do more frequent activities,” he told a news agency. [emphasis mine]

The highlighted language is patently false. India has never launched 9 spacecraft in a year. Last year it set a record with 7 launches. This false overstatement casts some doubt to me of the sincerity of the second claim, that the agency wishes to shift as much responsibility to the private sector as possible. Government agencies rarely give up power. In the U.S. the decision by NASA to shift from NASA-built rockets to commercially-built rockets took decades (occurring reluctantly in 2008 after years of lobbying), and even a decade after that decision the transition is hardly guaranteed.

Nonetheless, that ISRO officials are setting a goal of 18-19 launches a year indicates that they truly do want to compete with the big launch players.

ESA to lead international effort to track falling Chinese space station

9:50 am

The European Space Agency has taken the lead position in an international effort to track China’s falling Tiangong-1 test space station module.

The goal of the effort is to improve the accuracy of predicting the fall of such objects. Tiangong-1, at 8.5 tons, is big enough for some pieces to survive re-entry and crash to the ground. Improving the predictions of where it will fall will reduce the chances of the debris causing harm.

I first read of this effort from this news story, which contained in its last sentence one piece of interesting news having nothing to do with Tiangong-1:

The next such launch [of a Chinese space station module] will be of the Tianhe core module around 2019 on a new Long March 5B rocket, the country’s largest and most powerful so far. [emphasis mine]

It appears China has quietly renamed its big Long March 5 rocket, adding a “B” to the name. This name change strongly indicates what I have suspected for months, that the July launch failure has required China to significantly redesign the rocket. Apparently, the poor performance of the rocket’s first stage engines was caused by fundamental design problems.

Senate kills military “Space Corps”

9:38 am

As part of this year’s military budget bill, the Senate has eliminated a House proposal that the military create a new military branch called the “Space Corps.”

The bill also completely overhauls the management of the military’s space effort, as described in detail here.

The NDAA conference report blasts the Air Force for a “broken national security space enterprise,” strips key authorities from the service and shifts much of the management of military space to the deputy secretary of defense.

The second link focuses on the management changes, while the first reviews in great detail the Senate’s budget proposals, which (surprise, surprise!) give the military more money.

In addition to changes in space-related policy, the bill would also fully authorize a pay increase for service members, increase missile defense, and add additional ships and aircraft. “The bill fully funds the 2.4% pay raise our troops are entitled to under law while blocking the President’s ability to reduce troop pay,” according to the summary.

It authorizes funding for a wide variety of additional military hardware including 90 F-35 Joint Strike Fighters across the service branches — 20 more than requested by President Donald Trump’s initial budget — and three additional Littoral Combat Ships.

The bill also “adds $4.4 billion above the President’s initial budget request to meet critical missile defense needs” — authorizing up to 28 additional ground-based Interceptors and “requiring the Missile Defense Agency to develop a space-based sensor layer for ballistic missile defense,” according to the summary.

However, the bill would also set defense spending well above the $549 billion cap under the Budget Control Act [sequestration] and Senate Democrats have vowed to block major increases to defense spending without equal increases for domestic programs.

I am not sure what to make of the management changes, though I like the elimination of the Space Corps, which was an absurd waste of money. The proposed budget increases are disturbing, however. I am especially appalled (but not surprised) at the push to eliminate sequestration, which has been the only bill passed by Republicans that has done anything to control the federal governments wasteful spending.

New study confirms the cost effectiveness of commercial crew

8:18 pm

Capitalism in space: A new study shows that the commercial private cargo capsules are far more efficient then the space shuttle was in delivering cargo to ISS.

According to the new research paper by Edgar Zapata, who works at Kennedy Space Center, the supply services offered by SpaceX and Orbital ATK have cost NASA two to three times less than if the space agency had continued to fly the space shuttle. For his analysis, Zapata attempted to make an “apples to apples” comparison between the commercial vehicles, through June 2017, and the space shuttle.

Specifically, the analysis of development and operational expenses, as well as vehicle failures, found that SpaceX had cost NASA about $89,000 per kg of cargo delivered to the space station. By the same methodology, he found Orbital ATK had cost $135,000 per kg. Had the shuttle continued to fly, and deliver cargo via its Multi-Purpose Logistics Module, it would have cost $272,000 per kg.

…The detailed study then attempts to calculate the costs of the commercial cargo and crew programs combined, comparing that total to continued shuttle flights, which could carry both supplies and astronauts at the same time. Zapata’s best estimate is that the commercial programs cost only about 37 to 39 percent of what it would have cost NASA to continue the space shuttle program.

The benefits of the private programs go beyond cost savings, however. With multiple providers, NASA now has redundancy in case of a failure of supply lines to the space station. And there are indirect benefits as well, especially from supporting the efforts of US companies to develop new spacefaring technologies.

None of this is really news. There was once a time in the U.S. where these facts were understood without much thought. Americans once knew that private enterprise, competition, and freedom always work better than government-imposed projects. Today however we live in a post-freedom America, where the idea of depending on Americans to use their innovative talents freely to get things done is considered oppressive and racist, and must be squelched by a much wiser government.

Surprise! First unmanned launch of SLS might be delayed until 2020

8:05 pm

Yawn. NASA admitted today that the first unmanned launch of SLS, set for December 2019, might be delayed until June 2020.

NASA’s review considered challenges related to building the SLS rocket’s core stage, issues with constructing Orion’s first European service module and tornado damage at the Michoud Assembly Facility in New Orleans, NASA officials said in a statement.

“While the review of the possible manufacturing and production schedule risks indicate a launch date of June 2020, the agency is managing to December 2019,” Acting NASA Administrator Robert Lightfoot said in a statement. “Since several of the key risks identified have not been actually realized, we are able to put in place mitigation strategies for those risks to protect the December 2019 date,” Lightfoot added.

Gee, only yesterday I thought I was going out on a limb to say that the first manned flight of SLS wouldn’t happen until 2024. It looks like I wasn’t going very far out on that limb. If the first unmanned mission doesn’t happen until June 2020, the next SLS launch (using its own second stage for the first time) cannot happen until around April 2023. That mission will likely be unmanned, launching Europa Clipper. The third SLS flight, as yet unbudgeted by Congress, would then fly humans, and will likely be scheduled for 2024, though I am certain that will be an unrealistic launch date.

More likely the first manned flight of SLS will not occur before 2025, twenty-one years after George Bush first proposed it and fourteen years after the last shuttle flight. By that time the cost for this boondoggle will have risen to more than $50 billion.

2025 is about seven years in the future. I will also bet in that time both SpaceX’s Falcon Heavy and Blue Origin’s New Glenn rockets will have become operational, with both flying manned capsules. In fact, I expect them both to send human capsules to the Moon several times before SLS even gets its first manned flight off the ground. And they will do it for about a tenth the cost.

So obviously, our Congress and President know what to do! They are going to double down on SLS, pouring more money into this black hole, while making another decade of false promises about it that will never be fulfilled. Based on everything I have read coming from NASA and the National Space Council, I would be fooling myself to think otherwise.
