White House objects to House language on military space

9:45 am

The White House today released a detailed statement listing its objections to the House language on the upcoming military space authorization bill and threatening a veto if the Senate version is not passed.

Their objection seem to center on two issues. First, while the administration has accepted the idea of a space corp within the Air Force rather than a separate new military branch, they appear prefer the Senate language for this change. This disagreement appears relatively minor in the entire scheme of things.

Second, and more significantly, the White House has objections to the planned launch contract set up the Air Force has been pushing that would have them pick two launch providers now for all their launches through 2024, rather than allow all comers to bid on those launches as they came up.

On the National Security Space Launch program, the administration “strongly objects” to HASC [House Armed Services Committee] Chairman Adam Smith’s Section 1601 language “as it would increase mission risk for the nation’s national security satellites.”

Section 1601 would mandate that the Air Force compete contracts for any launches beyond 29 launches during the period from fiscal year 2020 to fiscal year 2024. This section would also mandate that the Air Force provide up to $500 million to launch companies that either win a Phase 2 contract after fiscal year 2022 or win a Phase 2 contract but are not part of a Launch Service Agreement, in order to meet national security-unique infrastructure and certification requirements for a Phase 2 contract. This section also require a notification of the selection in fiscal year 2020 of the two providers for Phase 2 launches.

The administration opposes these provisions. “After careful and considered study, DoD determined that a contract for national security space launch requirements over the course of five years would optimize warfighter flexibility, minimizes mission risk, and provides exceptional value to the taxpayer,” says the White House statement. “Confining Phase 2 to fewer missions would increase per-launch cost while simultaneously introducing risk and costs for some intelligence payloads. Finally, notifying Congress prior to a contract would be a departure from long-standing tradition and might put DoD at a greater risk of a protest.”

To put this in simple terms, the House language was an attempt to open up the bidding, while also offering $500 million development money to any company who missed out initially. The White House, and the Air Force, wish to restrict the bidding process, and don’t want to pay that extra $500 million.

All of this I think will become irrelevant the first time the Air Force issues a bid offer for a launch contract but restricts bidding to only two launch companies, even if a third or fourth is available and capable of fulfilling the contract. The excluded launch companies will sue for the right to bid, and they will win.

Beresheet design adopted by Firefly & Israeli private partnership

9:17 am

Capitalism in space: The American smallsat launch company Firefly Aerospace announced today that they will be partnering with a private Israeli company to use the design of Beresheet to build their own lunar lander for NASA.

Firefly Aerospace announced that it is partnering with Israel Aerospace Industries (IAI) to create a new lunar vehicle based on the crashed spacecraft’s blueprints. Firefly says this lander will build upon “lessons learned” from the accident to ensure that the new lander does not meet the same fate.

…If Firefly does mount a lunar mission, the company’s lander, called Genesis, will leverage much of the Beresheet design as well as the IAI team’s flight experience. “Firefly Aerospace is excited to partner with Israel Aerospace Industries to provide the only NASA CLPS program flight-proven lander design,” Shea Ferring, Firefly’s vice president of mission assurance, said in a statement. The name of the lander is also a nod to Beresheet, which means “Genesis” in Hebrew.

It appears that a group of engineers from the non-profit SpaceIL, that built Beresheet, have teamed up to form their own company. It also appears that they have some rights to the spacecraft’s design, and could take them with them.

Firefly is competing for a NASA contract to land on the Moon. This deal strengthens their bid considerably.

Study says space radiation less of a risk

9:05 am

A newly released study now claims that, based on a long term review of astronauts who have spent a considerable time in space, it appears that space radiation does not cause an increase in cancer later in life.

The new study analyzed information from 418 space travelers, including 301 NASA astronauts who had traveled to space at least once since 1959, and 117 Russian or Soviet cosmonauts who had traveled to space at least once since 1961. These participants were followed for about 25 years, on average.

During this time, 89 of the participants died. Among the 53 NASA astronauts who died, 30% died from cancer and 15% from heart disease; while among the 36 Russian or Soviet cosmonauts who died, 50% died from heart disease and 28% from cancer.

The researchers used a special statistical technique to determine whether deaths from cancer and heart disease likely had a common cause — in this case, the common cause would be space radiation. But their results did not point to a common cause of death. “If ionizing radiation is impacting the risk of death due to cancer and cardiovascular disease, the effect is not dramatic,” the authors wrote in their study, published July 4 in the journal Scientific Reports.

This story first appeared about two weeks ago, but I didn’t think it significant, and still don’t. The sample is just not large enough to draw any solid conclusions. Moreover, this is exposure in low Earth orbit, not on interplanetary missions where the radiation risk is higher. It would be a big mistake for future space engineering to accept these findings blindly.

Still, news reports keep popping up about it, and I decided I should at least note it here on Behind the Black.

Chang’e-4/Yutu-2 return to dormant mode for lunar night

8:59 am

According to one story in the Chinese press today, the science teams running Chang’e-4 and Yutu-2 on the far side of the Moon have now put both into dormant mode for the coming lunar night after completing their seventh lunar day.

What is intriguing about this short story is that while to lauds the work done by Chang’e-4 during that seventh lunar day, it says nothing about Yutu-2. Early comparable reports would have at least told us how far the rover moved during the lunar day. This time they say nothing at all about Yutu-2, other than it has been placed in dormant mode.

It could very well be that they had a problem with the rover. Sadly, China is not an open society. We can only wait for them to tell us.

Private lunar lander company files for bankruptcy

8:52 am

Capitalism in space: Former Google Lunar X-Prize competitor Part Time Scientists has now filed for bankruptcy.

The company, with about 60 employees, has emphasized a number of partnerships with major corporations, such as Audi, Vodafone and Red Bull Media House, a subsidiary of beverage company Red Bull. The company is also teamed with ArianeGroup to study development of a lunar lander mission for ESA.

PTScientists, though, had suffered delays in the development of its lunar lander. The company said last November its lander could launch as soon as late 2019, a date it revised in January to no earlier than the first quarter of 2020. However, at a conference in early June, a company official said that lander mission would now launch no earlier than the second half of 2021 as it continues to work on the lander’s design.

It appears to me that they simply were never able to raise the capital necessary to build their lander, despite these partnership deals.

Hayabusa-2 begins second touch&go sample grab on Ryugu

8:26 am

The Hayabusa-2 science team has begun the approach to Ryugu for the spacecraft’s second tough-and-go sample grab.

The link outlines the plan and timing of the operation. You can view real-time images taken by the probe’s navigation camera here. The actual touchdown will take place on July 11 (Japan time).

You can also view a set of stereoscopic images of Ryugu produced by Brian May, lead guitarist of Queen who clearly wants to return to his roots as a trained astrophysicist.

As they note at the first link:

The 2nd touchdown is the last big operation at Ryugu for the Hayabusa2 project. We will proceed with caution and the upmost care. Please wish us success…!

If successful, their next big operation will be getting those samples back to Earth.

Faking gravity in space with a spinning table

2:38 pm

Researchers at the University of Colorado in Boulder are experimenting with the use of a rotating table to give space-farers short doses of artificial gravity in order to mitigate the negative consequences of weightlessness.

In a series of recent studies, the pair and their colleagues set out to investigate whether queasiness is really the price of admission for artificial gravity. In other words, could astronauts train their bodies to tolerate the strain that comes from being spun around in circles like hamsters in a wheel?

The team began by recruiting a group of volunteers and tested them on the centrifuge across 10 sessions.

But unlike most earlier studies, the CU Boulder researchers took things slow. They first spun their subjects at just one rotation per minute, and only increased the speed once each recruit was no longer experiencing the cross-coupled illusion. “I present at a conference and everyone says, ‘she’s the one who spins people and makes them sick,'” Bretl said. “But we try to avoid instances of motion sickness because the whole point of our research is to make it tolerable.”

The personalized approach worked. By the end of 10th session, the study subjects were all spinning comfortably, without feeling any illusion, at an average speed of about 17 rotations per minute. That’s much faster than any previous research had been able to achieve.

The idea is that you could install this rotating table on a interplanetary ship, and have its occupants periodically spend time on it to get their daily dose of gravity. This way you would not have to build a giant spinning spaceship.

The research has potential. The one question that remains unanswered and is probably central to this concept is how little gravity is needed to avoid the problems of weightlessness. Right now, we do not know. It could be for example that 30 minutes at 1/10 g could do the job. Or maybe 1 g for 2 hours. If the former the engineering challenges become minor. If the latter the problems are more difficult.

I am aware of only one centrifuge experiment ever done in weightlessness, on a Russian space station. They rotated a plant at a very tiny percentage of g’s and found it might help plants prosper in space. The data point however is too small, with no followup. This is the kind of research that should be going on on ISS, and is not.

Wheel update on Curiosity

11:38 am

Periodically, the Curiosity science team stops from its research to reassess the condition of the rover’s wheels. To do this they use the rover’s color camera, dubbed the Mast Camera (Mastcam), taking close-up pictures of the wheels to compare those with earlier photographs see if there has been any additional damage and deterioration over time.

Yesterday Mastcam took a new series of images of the rover’s wheels. Below are two pictures, the left taken on August 27, 2017, the right taken on July 7, 2019. I have annotated the images to help indicate where they match.

Light Sail 2 beams back first images

10:44 am

Capitalism in space: The Planetary Society’s privately funded spacecraft Light Sail 2, launched June 25 on SpaceX’s Falcon Heavy, sent back its first images from orbit on July 7.

The images are not very interesting to look at, mostly because their purpose is engineering. Two cameras took pictures of the light sail’s deployment equipment inside the spacecraft to show that it is still in good shape. Another picture showed the Earth, demonstrating that the camera will be able to image the deployment of the solar sail, which might occur as early as today. UPDATE: They have announced that the deployment will not occur prior to July 21.

Once deployed from a cubesat about the size of a loaf of bread, the sail will be about the size of a boxing ring. They will then attempt to use the sunlight bouncing off it to sail in space, changing the sail’s orbit.

The science team also announced the debut of a mission control website, where the public can see live updates whenever the spacecraft sends back new information. As I write this the solar sail is still listed as “stowed,” but that status will change once they attempt the deployment.

For the public this website will be especially useful once the sail deploys, because it will be very bright to observers on the ground. The site shows Light Sail 2’s present position, making it possible for viewers to better anticipate when they will be able to see it fly overhead.

Update: This post has been revised slightly to make it more accurate, as per a comment by reader Rex Ridenoure.

Amazon releases more details about proposed Kuiper satellite constellation

8:58 am

Capitalism in space: Amazon on July 4 submitted to federal regulators a more detailed description of its proposed 3,000+ Kuiper satellite constellation.

Amazon’s Kuiper System satellites will have a design life seven years — less than half that of a traditional geostationary communications satellite — and will be launched in five waves, according to a July 4 filing with the U.S. Federal Communications Commission.

The first wave consists of 578 satellites that would provide internet service in two horizontal coverage bands, one between 39 degrees north and 56 degrees north (roughly from Philadelphia north to Moscow) and another from 39 degrees south down to 56 degrees south (roughly from Hastings, New Zealand, to the top of Great Britain’s South Sandwich Islands in the Atlantic Ocean). The subsequent four waves would fill in coverage to the equator.

Amazon didn’t say when those satellites would launch or what launch vehicle they would use to reach orbit. Jeff Bezos, the founder of Amazon, also owns launch company Blue Origin, whose New Glenn orbital rocket is slated for a first launch in 2021.

If Amazon intends to use Bezos’ New Glenn rocket, this system cannot launch prior to 2021, at the earliest, and that means it will likely enter the internet competition with SpaceX and OneWeb late. This is not fatal for Amazon, but it will require them to offer something to their customers that will draw them away from the earlier constellations.

Fire at SpaceX Starhopper facility in Florida

8:49 am

A fire in SpaceX’s Florida facility yesterday, where it is building a Starship prototype, caused between $50,000 to $100,000 damages.

City spokesperson Yvonne Martinez confirmed a small fire broke out at the facility on Cidco Road around noon and that the Cocoa Fire Department was able to quickly extinguish it. She said crews suspected an electrical fault as the source of the fire.

“This afternoon, a small fire occurred at a SpaceX facility in Cocoa,” SpaceX spokesperson James Gleeson told FLORIDA TODAY. “The fire was contained to a sea van on site and extinguished thanks to the Cocoa Fire Department, which responded within minutes.”

“There were no injuries as a result of the fire, and the cause is under investigation,” he said.

Martinez said the fire department estimates about $50,000 to $100,000 in damages were sustained by the shipping container and equipment inside, as well as the adjacent building.

This will be a blow to the Florida SpaceX unit that is competing with the Boca Chica unit on the construction of Starship.

Branson sells 49% of Virgin Galactic, stock to be publicly listed

8:24 am

Capitalism in space: Richard Branson has sold 49% of Virgin Galactic in a deal that will have the company’s stock publicly listed by the end of 2019.

The firm will list its shares as part of a merger deal with Social Capital Hedosophia, a special-purpose acquisition company (SPAC) created by venture capitalist Chamath Palihapitiya. Social Capital Hedosophia, formed by Palihapitiya’s Social Capital and venture capital firm Hedosophia in 2017, will invest $800 million for a 49% stake in the combined company. The firm will have an enterprise value of $1.5 billion, Virgin Galactic said.

…Branson’s space venture would be the first publicly-listed human spaceflight firm, with the stock market listing slated to take place in the second half of 2019.

Branson had been in talks with Palihapitiya since he suspended talks over a Saudi investment in his space companies last year. Riyadh had planned to invest a total of $1 billion into Virgin Galactic and Virgin Orbit, which focuses on small satellites, but the deal fell through over the murder of journalist Jamal Khashoggi.

Branson was the person who said the Saudis backed out because of Khashoggi, but I personally do not believe that story. What I think happened was that, after 15 years of empty promises and no tourist flights, the Saudis suddenly realized that Virgin Galactic was a bad investment, and backed out. Branson now needs cash to keep the company afloat.

I am honestly unfamiliar with the ways of Wall Street. I do not know whether being “publicly listed” means the stock will be available for trade. If so, I expect the stock value to quickly plunge.

Reused Falcon 9 wins NASA launch contract instead of Pegasus

10:04 pm

Captalism in space: NASA has awarded SpaceX a Falcon 9 launch contract using a reused first stage for its next X-ray telescope, the Imaging X-ray Polarimetry Explorer (IXPE)..

SpaceX will charge NASA just over $50 million, its normal price for a reused Falcon 9 and significantly less than NASA has previously paid for this kind of launch. More important, the telescope had been designed with the expectation that it would be launched using Northrop Grumman’s Pegasus rocket. It appears NASA had instead decided to bypass Pegasus, partly because it probably costs more, and partly because there is some issue with Pegasus that has delayed the launch of NASA’s ICON since 2017.

In fact, that ICON launch is the only contract that Pegasus presently has, and it is charging NASA $56 million for that launch, with NASA also having to bear the additional costs associated with the delays caused by Pegasus. All these issues, plus the loss of the IXPE launch, strongly suggests that Pegasus is in big trouble. It does not appear that, as it is presently being marketed, it is able to garner any business.

Engineers adjust Voyagers 1 & 2 because of steadily dropping power

6:35 pm

In recognition that the available power on both Voyager 1 and Voyager 2 continues to drop due to the age of the spacecraft, engineers have decided to make some major changes in how they operate both spacecraft.

For example, to save power on Voyager 2 they have turned off the heaters for the instrument that confirmed last year that the spacecraft had entered interstellar space. Even so, the instrument is still functioning and sending back data. It is expected it will continue to work for some time before finally succumbing to the cold of deep space.

They have also decided to reactivate the back-up thrusters on Voyager 2, just as they did with Voyager 1 in 2017.

Another challenge that engineers have faced is managing the degradation of some of the spacecraft thrusters, which fire in tiny pulses, or puffs, to subtly rotate the spacecraft. This became an issue in 2017, when mission controllers noticed that a set of thrusters on Voyager 1 needed to give off more puffs to keep the spacecraft’s antenna pointed at Earth. To make sure the spacecraft could continue to maintain proper orientation, the team fired up another set of thrusters on Voyager 1 that hadn’t been used in 37 years.

Voyager 2’s current thrusters have started to degrade, too. Mission managers have decided to make the same thruster switch on that probe this month. Voyager 2 last used these thrusters (known as trajectory correction maneuver thrusters) during its encounter with Neptune in 1989.

It is thirty years since those thusters on Voyager 2’s were used. If they work it will be an incredible testament to the engineers who designed both spacecraft.

The Greatest Scientific Fraud Of All Time — Part XXIII

12:29 pm

Link here. The author continues a long running series outlining the data manipulation and tampering that has been going on at NOAA and NASA to distort the global temperature record so it will confirm the theories of global warming activists. As he notes,

Sure enough, there have been additional adjustments, as always in the same direction — older down, and newer up. But those adjustments between v.3 and v.4 have been relatively minor. More significantly, Kirye discovered a different maneuver which is even more incredible, and which he proves by direct links back to NASA’s own website: In the v.4 graphs that it provides, NASA has relabeled the hugely-adjusted v.3 data as “unadjusted.”

He pinpoints how NASA is now taking its adjusted data and labeling them unadjusted, so that it can justify even more adjustments, all always cooling the past and warming the present. As he adds,

Funny that once again, each one of the adjustments somehow enhances the warming trend. Is it really possible that never once does any new data, or adjustment to data, lead to a change in the other direction?

This is political hackwork disguised as science. Until the climate science community does something to stop this and clean up the mess in its global temperature data, they will find themselves unable to convince anyone of their scientific credibility. Which by the way is generally in the sewer.

Sunspot update June 2019: Down to zero again, with next cycle making an appearance

11:54 am

Below is the June graph of sunspot activity released by NOAA yesterday. As I do every month, I am posting it here, annotated to give it some context.

After three months of slightly increased sunspot activity, the Sun in June was essentially blank, with sunspots visible on its facing hemisphere on only five days. In addition, the 36 day stretch of spotless days that began in May and stretched through most of June was the longest such stretch since the last minimum in 2009.
June 2019 sunspot activity

The graph above has been modified to show the predictions of the solar science community for the previous solar maximum. The green curves show the community’s two original predictions from April 2007, with half the scientists predicting a very strong maximum and half predicting a weak one. The red curve is their revised May 2009 prediction, extended in November 2018 four years into the future.

Even while the solar minimum continues and heads for its low point, the first indications of the next solar solar cycle have appeared:

Threats of violence force cancellation of pro-life film screening

11:01 am

They’re coming for you next: A theater has cancelled a planned five day run of the pro-life film Unplanned because of numerous threats of violence against its management.

Salmar Community Association board member Chris Papworth confirmed on Thursday, July 4, that the board has agreed to pull the movie’s five-day run, which was set to begin on July 12 at the Salmar Classic. He said the difficult decision to cancel the film was made out of concern for the personal safety for Salmar Theatres management, who had received personal threats via social media.

“…[These threats included] an effort to dox employees or, specifically, the general manager, by releasing their personal information on social media and then encouraging people to go after them as the one responsible for some heinous act. We just aren’t prepared for those levels of hostility towards our general manager.”

I want to once again note the irrational level of hate and anger coming from the leftwing community (which is generally pro-abortion). Their disagreement with the political position of the film now apparently justifies violence and personal threats.

None of this will end well. Eventually the left’s hate and anger is not going to be satisfied with verbal threats or minor physical attacks. It is eventually going to compel them to acts of murder, because mere verbal threats and minor physical attacks will not be getting them what the want, emotionally. Only by killing their enemies can they satisfy that irrational hatred.

Astronomers find kilometer-sized asteroid with shortest year

10:10 am

Astronomers have found a kilometer-sized asteroid with a year only 151 days long, the shortest year of any asteroid.

The asteroid has been dubbed 2019 LF6.

In its orbit, the asteroid swings out beyond Venus and, at times, comes closer in than Mercury, which circles the sun every 88 days. 2019 LF6 is one of only 20 known “Atira” asteroids, which are objects whose orbits fall entirely within Earth’s.

Atira asteroids are difficult to find because they are so close to the Sun, which makes observations difficult if not impossible. Expect more such discoveries as the technology to make these observations improves.

UCLA professor found guilty of stealing military technology for China

9:41 am

A UCLA professor has been found guilty of stealing military technology and sending it to China.

UCLA adjunct professor Yi-Chi Shih was convicted June 26 on 18 federal charges, Newsweek reported, and could now lose hundreds of thousands of dollars, while also facing up to 219 years behind bars for numerous violations of the law. These include conspiracy to break the International Emergency Economic Powers Act (IEEPA), committing mail and wire fraud, lying to a government agency, subscribing to a false tax return, and conspiring to gain unauthorized access to information on a protected computer, according to a Department of Justice news release.

Shih and co-defendant Kiet Ahn Mai tried to access illegally a protected computer owned by a U.S. company that manufactured semiconductor chips called monolithic microwave integrated circuits (MMICs). MMICs are used by the Air Force and Navy in fighter jets, missiles and missile guidance technology, and electronic military defense systems.

The chips were exported to Chengdu GaStone Technology Company (CGTC), a Chinese company, without a required Department of Commerce license. Shih previously served as the president of CGTC, which made the Commerce Department’s Entity List in 2014 “due to its involvement in activities contrary to the national security and foreign policy interest of the United States – specifically, that it had been involved in the illicit procurement of commodities and items for unauthorized military end use in China,” according to court documents cited by the DOJ.

The only surprise here is that the these guys got caught. Since the late 1990s China has been making aggressive effort to steal American know-how, and has largely been successful. The visible result of that effort has been their space program, almost all of which began with technology thefts.

University student attacked for wearing MAGA/Trump paraphernalia

9:32 am

They’re coming for you next: A University of Florida student was attacked for wearing a MAGA hat and other pro-Trump clothing, with the attackers screaming obscenities at him while trying steal some of that clothing.

As Weldon grabbed a late-night snack on July Fourth across the street from campus he said he was surrounded by a group of college-aged peers who verbally harassed him, pushed him, ripped a Trump pin off his shirt, and tried to swipe his MAGA hat.

“It just goes to show there is a lot of people on the Left that don’t care or know anything about you, but they see one aspect of who you are and instantly have this blind hatred for you,” Weldon told The College Fix in a telephone interview Sunday. “It’s extremely disappointing.” [emphasis mine]

At first he did not report the incidence to the police because no real harm had been done, but then changed his mind and filed a police report, for this reason:

[H]e thought about it some more, especially the argument that while he was a “big guy” and could handle the situation, what if the next person couldn’t?

I want to focus on the highlighted words “blind hatred.” It encapsulates the modern left and their attitude towards Trump and any of his supporters. They no longer are rational. They simply hate. This vicious emotional response now has them cursing Trump vilely for no reason, and attacking America and our history, merely because Trump happens to have said a good word about America and that history.

This hatred is also causing them to increasingly turn to violence and abuse against anyone who supports Trump, as illustrated by this story and innumerable others. Support Trump and their hatred immediately causes them to see you as a jack-booted thug who deserves to be beaten to a pulp.

The problem is that this hatred then causes the left to act exactly like the jack-booted thugs they imagine Trump and his supporters to be.

Hate is a very bad thing. It is even worse in the field of politics, because there it leads to the abuse of power and oppression, for no reason other than hate. And unless the left takes a breath and starts to use its brain instead of blind emotional hate, we can expect them to do some very bad things to their opponents should they regain power.

Conservative wins in Greece

8:39 am

A new conservative Greek prime minister took office today following a strong election victory yesterday over the incumbent leftist government.

Conservative party leader Kyriakos Mitsotakis was being sworn in as Greece’s new prime minister Monday, a day after his resounding win over left-wing Alexis Tsipras, who led the country through the tumultuous final years of its international bailouts.

Mitsotakis’ New Democracy party won 39.8% of the vote, giving him 158 seats in the 300-member parliament, a comfortable governing majority. Tsipras’ Coalition of the Radical Left, or Syriza, garnered 31.5%. The extremist right-wing Golden Dawn, Greece’s third largest party during the height of the financial crisis, failed to make the 3% threshold to enter parliament. [emphasis mine]

This conservative victory probably is more about with the pain caused during Greece’s recent financial crisis, under leftist rule, and less about rejecting leftist policies. Greece had become bankrupt after decades of bad policy at the top by everyone, and the tough love required to get them out of that hole was almost certainly the reason the left lost.

Still, this election continues a general worldwide trend in the world’s democracies, whereby the voters reject the status quo by throwing an incumbent out of office for a new face. The trend also suggests that the new face has a golden opportunity to change that status quo, in a radical manner.

Note that the status quo for the past half century has been increased centralized power by governments. Can anyone guess what a change from that would be?

Hayabusa’s 2nd sample grab on Ryugu

8:11 am

Target 2nd landing site on Ryugu
Click for full resolution image.

The Hayabusa-2 science team today posted detailed information in two posts about the process that led to the decision to attempt a second touch-and-go sample grab on the surface of Ryugu. The first part outlined in detail what they have learned about the target landing site. The second part described the decision making process.

The image to the right, reduced to post here, is from the second part. It shows the crater they created with a projectile and the target landing site, labeled C01-C. The dark areas show the changes on the surface following the impact. Their analysis of the target site found that, first, they can land there without undue risk to the spacecraft, and, second, they have a high probability of getting ejecta thrown up from the crater in their sample.

Based on all this information, they decided to attempt it, on July 11. I especially like how they stated this decision:

The second touchdown will be attempted on July 11. We will proceed with our mission with care, but boldly go. [emphasis mine]

I am sure my readers will recognize the literary reference.

Man who wanted to be the first African in space killed in road accident

7:40 am

A South African man who had won a competition to fly on a suborbital tourist flight has been killed in a motorcycle accident.

Mandla Maseko, 30, was killed on Saturday, a family statement says.

In 2013, the South African Air Force member beat one million entrants to win one of 23 places at a space academy in the US. Nicknamed Afronaut and Spaceboy, Maseko described himself as a typical township boy from Pretoria.

…He had spent a week at the Kennedy Space Centre in Florida doing tests in preparation for an hour-long sub-orbital flight, originally scheduled for 2015. Challenges included skydiving to earth from 10,000 feet and a test charmingly known as the “vomit comet”.

But the chance never came to go into space. The company organising the flight, XCOR Aerospace, went bankrupt in 2017, news site Space.com reported.

All around a terrible tragedy.

DSCOVR in safe mode

9:25 am

The solar wind monitoring satellite DSCOVR has gone into safe mode.

It is at present unclear what the problem is, or whether they can recover the spacecraft.

DSCOVR’s history is packed with political shenanigans. It was first proposed by Gore as Triana, with its only purpose to take global pictures of the Earth so Gore and the left could use these images for environmental propaganda. Bush canceled it, partly because it really had no legitimate scientific purpose and partly to prevent the left this propaganda tool. It was resurrected during the Obama administration but with a more useful purpose, providing early solar wind data so that Earth-based power grids could get prepared should a major solar storm be incoming. NASA’s other solar wind monitors ACE and SOHO, were already decades beyond their planned lifespan, and the space agency, the solar weather community, and especially the world’s electrical power industry, was desperate to get a new satellite in space.

Ironically, with DSCOVR’s shutdown we are still dependent on ACE and SOHO. Nor is there any replacement satellite anywhere close to launch.

X-37B photographed in orbit

2:17 pm

X-37B as seen by telescope
Click for full image.

An amateur astronomer this week was able to get a photograph of the X-37B presently in orbit about 200 miles high.

The [X-37B] is a small version of the classic Space Shuttle, it is really a small object, even at only 300 km altitude, so dont expect the detail level of ground based images of the real Space Shuttle. Considering this, the attached images succeeded beyond expectations. We can recognize a bit of the nose, Payload Bay and tail of this mini-shuttle with even a sign of some smaller detail.

The image on the right, reduced and cropped to post here, shows the image with a graphic of the spacecraft in comparison.

The graphic assumes the X-37B’s cargo door is open, but the actual image does not match this, to my eye. Instead, it appears partly open, with some kind of large object protruding from the cargo bay.

This X-37B spacecraft, one of two the Air Force flies, was launched by SpaceX in September 2017 and has now been in space more than 664 days, with no indication yet when it will return to Earth. The present record is 718 days for the longest X-37B flight, set by the Air Force’s other X-37B. It appears likely that this spacecraft will exceed that record.

Russian Soyuz rocket successfully launches 33 satellites into orbit

10:56 pm

In its first Vostochny launch in 2019, Russia today used its Soyuz rocket to successfully launch a variety of weather, engineering, and Earth observation satellites totaling 33 into orbit.

As I write this the satellites are in orbit but have not yet been deployed by the rocket’s Fregat upper stage, a process that will take several hours as it moves them into a variety of orbits.

Many of the smaller satellites on this rockets are commercial cubesats, and are Russia’s effort to regain some of its lost commercial business that had been captured by SpaceX. They are also a sign of the changing launch business. Previously Russia’s commercial flights were all on its larger Proton rocket because the satellites were larger. Now the business is shifting to the smaller and recently more reliable Soyuz, because smaller satellites are beginning to dominate the industry.

The leaders in the 2019 launch race:

9 China
8 SpaceX
6 Russia
5 Europe (Arianespace)
3 India
3 Rocket Lab

The U.S. continues to lead China 14 to 9 in the national rankings.

An inteview with George Zimmerman

1:50 pm

Link here. Read it all if you have any interest at all in finding out the truth. The key part of this story, which was confirmed by a not-guilty jury decision, is this:

Headed in the direction that the lights came from coming around the side of one of the townhouses to the “T” in the sidewalks [Zimmeran] was, without notice, punched in the face by Trayvon, instantly breaking his nose. Trayvon then grabbed George and tried to throw him to the ground multiple times. George held his own for a little bit but eventually was thrown to the ground. Once again George referred to the sketch showing me where they were by this time, which was a little further up the sidewalk from the initial attack. He said that the ground sloped down on one side of the sidewalk and his legs were down the hill while his head was on the sidewalk. Trayvon was now on top of George punching him repeatedly in the face, MMA style, as George described. Every time George tried to sit up Trayvon would slam him back down to the ground and in-turn his head would bounce off the sidewalk, causing him excruciating pain.

To get away from the pain being inflicted on his head, George tried sliding down the hill out from underneath Trayvon. This caused George’s red windbreaker to slide up revealing his Kel- Tec PF-9 9mm handgun holstered on his hip.

Trayvon noticed the gun and said, “You’re gonna die tonight!” At that point, George realized that it wasn’t his gun or Trayvon’s gun, it was “the” gun in the fight!

Without any prior experience of drawing and shooting from the holster, George knew it was either now or never. He unholstered the firearm and fired one shot at the man who he felt was trying to take his life. The response from Trayvon was like that of an old Western movie. He said, “Ya got me!” At that second George thought his shot missed. To him, it seemed as if Trayvon was making a statement to concede defeat and not that he actually was hit by the bullet.

In that instance George wasn’t worried about his safety or that somebody was trying to kill him, he was more concerned that he missed Trayvon and might have hurt somebody else in a nearby house. To me, this was one of many enlightening times in our meeting. More concerned for the life of his neighbors than his own life.

All Zimmerman was doing at that moment was trying to save his own life. All of this was obvious at the time, for all those who were willing to do any research into the facts. Yet, as punishment for not allowing himself to be killed by a street thug, our bigoted and political cultural elites decided to destroy this poor man’s life anyway, because it gave them a great vehicle for ramping up race hatred and anti-American propaganda.

This says far more about them than it does about Zimmerman, or Trayvon Martin.

Jupiter’s changing Great Red Spot

12:53 pm

The changing Great Red Spot
Click for full resolution image.

Using Juno images produced during four different orbits, beginning in July 2017 through February 2019, citizen scientist Björn Jónsson has created a montage, reduced in resolution to post on the right, that shows the changes that have occurred in Jupiter’s Great Red Spot during that time. As he writes,

This is a montage of four map-projected [Spot] mosaics processed from images obtained during these perijoves (at the time of this writing perijove 20 is the most recent perijove). The mosaics show how the [Spot] and nearby areas have changed over the course of the Juno mission. The mosaics cover planetographic latitudes 4.7 to 38 degrees south.

The resolution of the source data is highly variable and this can be seen in some of the mosaics. The viewing geometry also varies a lot. Some of the images were obtained almost directly above the [Spot] (in particular some of the perijove 7 images) whereas other images were obtained at an oblique viewing angle (in particular the perijove 17 images).

These are approximately true color/contrast mosaics but there may be some inaccuracies in areas where the original images were obtained at a highly oblique angle. The contrast is also lower in these areas.

What strikes me the most is how the Spot itself seems relatively unchanged, while the bands and surrounding cloud formations changed significantly during this time.

Paper ballot count puts establishment Democrat ahead of socialist in NYC primary

9:14 am

The count of paper ballots submitted during last week’s Democratic Party primary for Queens district attorney has put the establishment candidate Queens Borough President Melinda Katz ahead–by 20 votes–of Tiffany Cabán, the socialist endorsed by Alexandria Ocasio-Cortez.

Queens Borough President Melinda Katz is now leading lefty insurgent Tiffany Cabán in the Democratic primary for Queens district attorney — a stunning reversal of fortunes after the race went into a paper ballot count with Cabán ahead by more than 1,000 votes last week.

About 6,000 paper ballots remained to be counted, and as the Board of Elections tallied the final votes Wednesday night, Katz was leading Rep. Alexandria Ocasio-Cortez-backed Cabán by a razor-thin 20 votes, two sources told The Post.

Both sides acknowledged the narrow margin would trigger a recount — but that didn’t stop Katz from declaring victory Wednesday night.

I find this story most amusing, as it reminds me of Minnesota and the recount of paper ballots that gave Democrat Al Franken his victory over Republican Norm Coleman in 2008. Many fishy things seemed to occur during that recount that has always made it suspicious.

Either way, it appears the Democratic establishment, having realized what a political disaster Ocasio-Cortez has been, did not want another such socialist representing them in New York and appears to have moved to make sure it didn’t happen. For example, there’s this story: Queens DA frontrunner Tiffany Cabán dedicates ‘victory’ to Rikers inmates

Rikers Island inmates are first in Tiffany Cabán’s heart.

“Our victory belongs to folks who have been locked up on Rikers simply because they could not afford their bails,” she said Saturday, days after early results showed her the likely winner of the Democratic primary for Queens district attorney.

Though politically this position by her, allied more with criminals than ordinary honest citizens, isn’t really much different than the bulk of today’s Democratic Party, her willingness to state those positions openly is why the establishment Democrats in Queens are desperate to stop her.

Hat tip reader Cotour.

Update on planned Russian additions to ISS

8:54 am

Link here. The article describes present status of Russia’s new modules to ISS, along with their tentative launch dates in the early 2020s.

We should not take these dates too seriously. Russia is literally decades behind schedule in launching this stuff. Whether they can finally get them in orbit now, with their present shortage in cash, remains unknown.
