SpaceX about to set reuse record for fastest turnaround ever

9:09 am

Capitalism in space: If tomorrow’s launch of a South Korean military satellite by SpaceX’s Falcon 9 rocket succeeds, it will set a new all-time record for the fastest turnaround of a used rocket, 44 days.

The previous record was 54 days, set by the space shuttle Atlantis in 1984. The article notes however the spectacular differences:

By far the most impressive aspect of Falcon 9’s imminent record is the comparison between the resources behind Space Shuttle Atlantis’ 54-day turnaround and Falcon 9 booster B1058’s ~44-day turnaround. Around the time NASA and Atlantis set the Shuttle’s longstanding record, some 5000-10000 full-time employees were tasked with refurbishing Space Shuttles and the facilities (and launch pads) that supported them. Based on retrospective analyses done after the STS program’s end in 2011, the average Space Shuttle launch (accounting for the vast infrastructure behind the scenes) ultimately wound up costing more than $1.5 billion per launch – more than the Saturn V rocket the Shuttle theoretically replaced.

According to a uniquely detailed May 2020 AviationWeek interview with SpaceX CEO Elon Musk, Falcon 9 booster turnaround may cost as little as $1 million apiece and can be managed from start to finish by several dozen employees at most. In other words, even though SpaceX boosters are suborbital and stressed quite a bit less than orbital Space Shuttles, Falcon 9 reuse is approximately a thousandfold more efficient that Space Shuttle reuse. [emphasis in original]

I should add that SpaceX also has three more launches on tap for the rest of July. If all lift off, the company will have launched four rockets in only three weeks, which in itself will be a record. No private rocket company has ever launched so frequently and so routinely. And only Russia during its Soviet Union heydays has come close to launching with this frequency.

Comet Neowise: NOW is the time to go see it

8:59 am

Comet Neowise is now visible each evening just after sunset. This article shows a bunch of images produced by people worldwide.

The comet will not be back for thousands of years, so this will be your only chance to see it. And usually good evening-view comets occur only once every few decades, usually not more than once or thrice every century. If you want to see a comet in all its glory, Comet Neowise is giving you a chance, and now is the time to look.

Midnight repost: Doing the Grand Canyon right

11:59 pm

My Behind the Black tenth anniversary retrospective continues: Tonight’s repost is an essay I wrote on July 15, 2013 shortly after one of Diane and I’s annual hiking trips to the bottom of the Grand Canyon.

——————————
Doing the Grand Canyon right

The Tonto Plateau

The one thing about the Grand Canyon that attracts hikers is its intimidating nature. People feel challenged by its large size and depth, and want to prove to themselves that they can do it.

The irony of this to me is that it is that intimidating nature that generally causes most people the most problems. People worry about the climb out. They worry about the heat. They worry about the lack of water. And they worry about vastness around them.

All of these things — the climb, the heat, the lack of water, and the vastness — must be dealt with. Each has caused the death of many visitors. Each could kill you if you are not prepared. In fact, one or all of these factors are probably the primary causes behind all of the approximately 300 rescues that occur each year at the Grand Canyon.

Yet, none of these factors is actually the biggest obstacle for most people trying to climb in and out of the Canyon. Instead, it is the worry about these things that causes people the most difficulties.

COVID-19 update: Though deaths up slightly, CDC says outbreak no longer qualifies as epidemic

11:40 am

U.S. daily COVID-19 deaths through July 12th

But we’re all supposed to die! Even though the last week has seen a slight uptick in the number of daily deaths from COVID-19 (as shown by the graph to the right [source]), the CDC’s latest data update, through July 4th, notes that as of that date the overall death rate put the Wuhan virus below their “epidemic threshold.”

Based on death certificate data, the percentage of deaths attributed to pneumonia, influenza or COVID-19 (PIC) decreased from 6.9% during week 26 to 5.5% during week 27, representing the eleventh consecutive week during which a declining percentage of deaths due to PIC has been recorded. The percentage is currently below the epidemic threshold but will likely change as additional death certificates for deaths during recent weeks are processed. [emphasis mine]

In other words, at the beginning of this month the numbers said the epidemic was over. To underline this point, the CDC’s totals also include deaths from pneumonia and influenza, which therefore reduces the death rate for the Wuhan flu even more.

(Note: The two spikes on the graph of daily deaths on May 7 and June 25 are because New York and New Jersey suddenly added a whole slew of new deaths, under suspicious circumstances.)

The increase in deaths during the past week probably reflects the increased number of cases in the past month. It also partly explains why the CDC has not officially declared the epidemic over. They expected the death rate to rise, and it has.

However, even that rise hardly ranks as an epidemic. » Read more

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

Midnight repost: The think tank culture of Washington

11:59 pm

The tenth anniversary retrospective of Behind the Black continues: The essay below, first posted on June 22, 2016, was the result of a Washington DC. trip, occurring during the heat of the presidential campaign just after Donald Trump had become the Republican candidate for president.

The impression I got of the Washington culture then has sadly proven more accurate than I would have ever guessed. And their response to Trump’s election was just as I feared.

———————————-
The Think Tank Culture of Washington

On Monday I attended and gave a presentation at the one-day annual conference of the Center for New American Security (CNAS) in Washington, D.C., in conjunction with the space policy paper I am writing for them, Exploring Space in the 21st Century.

CNAS was founded ten years ago by two political Washington insiders, one a Democrat and the other a Republican, with a focus on foreign policy and defense issues and the central goal of encouraging bi-partisan discussion. For this reason their policy papers cover a wide range of foreign policy subjects, written by authors from both political parties. The conference itself probably had about 1,000 attendees from across the political spectrum, most of whom seemed to me to be part of the Washington establishment of policy makers, either working for elected officials, for various executive agencies, or for one of the capital’s many think tanks, including CNAS.

I myself was definitely not a major presenter at this conference, with speakers like Vice President Joe Biden, Senator Lindsey Graham (R-South Carolina), and Senator Joe Reed (D-Rhode Island). I was part of a panel during one of the lunch breakout sessions, where approximately one third of the attendees came to have lunch while we spoke about space. I only had ten minutes to speak, and used that time to outline (1) the influence SpaceX is having on the entire launch industry and (2) the vast differences in cost, development time, and results between the Orion/SLS program and commercial space. Not surprisingly, the aerospace people from the big established companies appeared to be somewhat uncomfortable with what I had to say, though the Airbus people liked it when I made it clear I thought that the U.S. should allow foreign companies to compete for American business, including government launches.

Their discomfort was best illustrated by the one question asked of me following my talk, where the questioner said that I was comparing apples to oranges in comparing a manned capsule like Orion, intended to go beyond Earth orbit, with the unmanned cargo capsules like Dragon and Cygnus, that only go to ISS. I countered that though I recognized these differences, I also recognized that the differences were really not as much as the industry likes to imply, as demonstrated for example by SpaceX’s announcement that they plan to send Dragon capsules to Mars beginning in 2018. After all, a capsule is still only a capsule. The differences simply did not explain the gigantic differences in cost and development time.

I added that Orion compares badly with Apollo as well, noting that Apollo took about a third as long to build and actually cost less. I doubt I satisfied this individual’s objections, but in the end I think future policy will be decided based on results, not the desires of any one industry bigwig. And in this area Orion/SLS has some serious problems. I hope when my policy paper is released in August it will have some influence in determining that future policy.

My overall impression of CNAS, the speakers, and the people who attended was somewhat mixed. Having lived in the Washington, D.C. area from 1998 to 2011, when I attended many such conferences, I found that things haven’t changed much in the last five years. Superficially, everyone was dressed in formal business suits (something you see less and less elsewhere), and they also got to eat some fancy food at lunch.

On a deeper level my impressions were also mixed.

Russia’s next module for ISS passes tests

10:01 am

At last! Russia’s long-delayed next module for ISS, dubbed Nauka, has finally passed its vacuum chamber tests and is now scheduled for shipment to the launch site on July 21 to 23.

Construction of Nauka began in 1995, a quarter of a century ago. For comparison, in the last quarter of the 20th century Russia launched Salyut 1, Salyut 3, Salyut 4, Salyut 5, Salyut 6, Salyut 7, Mir, and its first five modules for ISS. All told those launches involved building and putting into orbit 18 different modules, with 14 comparable to Nauka in size and mass, all built and launched in about the same amount of time it has taken Russia to build Nauka alone.

At this pace it will take centuries for Russia to build its next space station, no less get to the Moon or Mars.

Problems at Europa Clipper

9:44 am

NASA has fired the project scientist for one overbudget and behind schedule instrument on Europa Clipper, and restructured work on a second instrument for similar reasons.

“We’ve been struggling on cost growth on Clipper for some time,” said Curt Niebur, program scientist for the mission at NASA Headquarters. “Overall, we’ve been largely successful in dealing with it, but late last fall, it became clear that there were three instruments that experiencing some continued and worrisome cost growth.”

The outcome of the reviews, he said, could have ranged from making no changes to the instruments to, in a worst-case scenario, terminating the instruments. The leadership of NASA’s Science Mission Directive recently decided to keep all three instruments, at least for now.

The fired scientist had been in charge of the mass spectrometer. At the moment they have installed a temporary replacement, and have put the instrument team on notice that it now has a very low priority. Should it fall further behind in schedule or budget it could easily be terminated.

The spacecraft’s imaging system also has schedule and budgeting problems, so much so that NASA was considering dropping the wide field camera, leaving Europa Clipper with only a narrow field camera. Right now both have been retained, but the wide field camera might still be dropped if costs continue to rise.

Midnight repost: Al Gore and the silencing of debate

11:59 pm

The Behind the Black tenth anniversary retrospective: Today’s repost is from August 29, 2011, and was one of my earliest essays describing the real meaning of the scientific method.

——————————–
Al Gore and the silencing of debate

Yesterday I posted a link to a story about Al Gore claiming that any expression of skepticism about global warming is to him no different than racism. Here again is what Gore said,

“There came a time when friends or people you work with or people you were in clubs with — you’re much younger than me so you didn’t have to go through this personally — but there came a time when racist comments would come up in the course of the conversation and in years past they were just natural. Then there came a time when people would say, ‘Hey, man why do you talk that way, I mean that is wrong. I don’t go for that so don’t talk that way around me. I just don’t believe that.’ That happened in millions of conversations and slowly the conversation was won. We have to win the conversation on climate.”

More than at any other time, Gore here has very successfully illustrated the differences between how climate skeptics debate the scientific questions of climate change versus how global warming advocates do it.

Police seize guns of Missouri couple used to defend their home from rioters

10:03 pm

They’re coming for you next: St. Louis police today used a warrant to search the home of the Missouri couple and seize the weapons they had used to ward off threatening rioters last month.

Authorities in St. Louis executed a search warrant Friday evening at the home of Mark and Patricia McCloskey, the couple who made headlines last month when they took up arms to defend their homes from protesters. During the search, police seized the rifle that Mark McCloskey was shown holding during the June 28 incident, KSDK-TV of St. Louis reported, citing information from a source.

The pistol that Patricia McCloskey held during the June confrontation was already in the possession of the couple’s attorney, the station reported.

There was no immediate indication that the McCloskeys were arrested or charged with a crime. [emphasis mine]

It appears to me that their only crime was that they are white and that they took up arms to defend their lives and home from a group of trespassers linked to Black Lives Matter/Antifa.

It might be possible that they did not have the guns legally (in the original video it clearly appeared they, especially the woman, had never held or used guns before). Nonetheless, they hurt no one, they were on their own property, the protesters were trespassers, and those trespassers had also made actual threats against them, their property, and even their dog. Their description of what happened matches well with the videos available.

In the June incident, Patricia McCloskey said, the couple was startled just before dinnertime when “300 to 500 people” entered the gated community where they live. “[They said] that they were going to kill us,” Patricia McCloskey told Hannity on Monday night. “They were going to come in there. They were going to burn down the house. They were going to be living in our house after I was dead, and they were pointing to different rooms and said, ‘That’s going to be my bedroom and that’s going to be the living room and I’m going to be taking a shower in that room’.”

So what does the local Democratic government do? Do they prosecute any rioters? No, they release them, and then go after these citizens to deny them the ability to defend themselves.

The McCloskeys fortunately have enough resources to hire a security company to protect themselves. Other ordinary citizens in St. Louis however be warned. If you take action to defend yourself, your local Democratic politicians will come after you. And they will move to disarm you so you will be helpless to the mob.

A great hike to do on Mars!

Knife Mesa at the exit from Kasei Valles
Click for full image.

Time to take a cool image and go sight-seeing. The photo to the right, cropped and reduced to post here, was taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) on May 25, 2020, and shows a spectacular knife-edge mesa, its cliffs more than 650 feet high on either side.

This knife mesa sits among a bunch of similar mesas, and appears to be in a region that could be called chaos terrain, formed by flowing water or ice along faults, cutting criss-crossing canyons with mesas between.

This mesa points east out from the Kasei Valley, the second largest canyon draining out from the Tharsis Bulge that contains Mars’ largest volcanoes. The overview map below provides some context, with the white cross indicating the location of today’s cool image.

COVID-19 and launchpad issues delay Ariane 6

10:00 am

The European Space Agency (ESA) confirmed today that the first launch of Arianespace’s Ariane 6 rocket will be delayed at least six months, to late 2021, due to lock downs related to the Wuhan flu panic, as well as construction issues at the rocket’s new launchpad.

“While we know that the maiden flight will not take place before the second semester of 2021, we cannot at this moment precisely quantify the delay, and we cannot provide an exact launch date,” Daniel Neuenschwander, ESA’s director of space transportation, said according to an ESA translation of remarks at a July 9 press event provided to SpaceNews. The French Association of Professional Journalists in Aeronautics, organized the event at ArianeGroup’s headquarters in Paris.

ESA hopes to have greater clarity on the delays in a few months, he said, according to the ESA translation.

It bodes bad for this rocket that they, at this time, have so little handle on the issues and the length of the delays.

Launch failure for China’s new Kuaizhou-11 rocket

9:49 am

For reasons not yet specified, China’s new Kuaizhou-11 rocket today failed on its inaugural launch.

Many reports will say that this is a commercial rocket developed by the private company Exspace. That is not true. Like all Chinese aerospace companies, they do their work wholly under the supervision of the Chinese government.

The development of the KZ-11 began in 2015, with a maiden launch originally scheduled for 2018. The rocket is developed by China Aerospace Science and Technology Corporation (CASIC) and commercialized by the China Space Sanjiang Group Corporation (Expace).

The launch vehicle can loft a 1,500 kg payload into a Low Earth Orbit (LEO) or 1,00 kg to a 700 km sun-synchronous orbit.

The KZ-11 solid launch vehicle adopts a mobile launch platform, integrated power supply equipment, test and launch control facilities, aiming facility and temperature control facility, to carry vehicles from the technical support center to launch site, complete temperature control of payload, vehicle test and launch.

CASIC is in many ways China’s equivalent of NASA. And everything described in the last paragraph above, from solid rockets to mobile launches, are technologies developed expressly for military purposes. China will not let such things out for commercial companies to use however they wish, no matter what they claim.

Midnight repost: Switching to Linux

11:59 pm

The tenth anniversary retrospective of Behind the Black continues: My contempt for Microsoft and its terrible Windows operating system is quite well known. I successfully switched to Linux back in 2006 and have never regretted it.

After seeing a number of my posts noting the advantages of Linux (or anything) over Windows, one of my readers, James Stephens, offered to write a series for Behind the Black describing step-by-step the process by which one gets and installs Linux on either a desktop or laptop computer. Below are the links to this series. I have since used it myself as a guide to convert two used Windows 7 notebooks (purchased for about $35 each) to my favorite flavor of Linux, both of which I use regularly as my travel computers.

I wish more people would do the same. I am sure almost everyone has an old computer they don’t use anymore. It will work like new with Linux. Dig it out, follow James’ instructions, and free yourself from Windows. I guarantee you will not be disappointed.

Genocide is coming to America

2:09 pm

In my last visit to Israel in 2018, my brother and sister-in-law took me sight-seeing to the northern parts of Israel near the Sea of Galilee. On our first night, we stayed at the home of one of their older friends, a man in his seventies.

That night we sat around their kitchen table so that they could catch up on family matters. At one point in the conversation our host reminisced about an older woman, now gone, who he had known in his childhood in the 1950s who had lived in Germany before and during World War II and had survived a concentration camp.

To paraphrase the story he told us, what this woman always remembered most starkly about that time, especially in the 1930s, was how difficult it was to get German friends who were not Jewish to believe the horrors she and other Jews were going through. To her, their calm nonchalant dismissal of the Nazi bigotry and oppression of Jews — too unbelievable to take seriously — was what had horrified her the most. Even twenty years later, it was this dismissal that appalled her the most, despite her time in a concentration camp and the death she had seen around her.

As he told us this story, what struck me was how similar my own experience has been. Time after time for the past four decades my liberal friends and relatives have refused to believe anything I say to them — always based on actual events — about politics and the growing corruption and bigotry within the Democratic Party. Like those decent Germans in the 1930s, these decent Americans find reasons to quickly dismiss what I say, without making any effort to find out if there is any merit to it.

In fact, less than two days after this very conversation it happened again. » Read more

Falcon 9 landing leg falls during retraction

10:15 am

Capitalism in space: During the processing to bring a used Falcon 9 first stage back to its hanger after its June 30th launch, one of the landing legs unexpectedly fell back to the ground during retraction.

I have embedded the video of the incident, cued to the event, below the fold. No one was hurt, and it appeared that nothing was damaged. It appears it happened because a cable holding the leg vertical snapped just before the leg got latched in place on the side of the rocket.

Solar Orbiter operational, first images to be released

10:05 am

Engineers have now confirmed that Solar Orbiter, having completed its first close fly-by of the Sun, is working perfectly and is producing images and data better than expected.

They will release to the public the first images on July 16.

“The first images are exceeding our expectations,” says Daniel Müller, Solar Orbiter Project Scientist at ESA. “We can already see hints of very interesting phenomena that we have not been able to observe in detail before. The 10 instruments on board Solar Orbiter work beautifully, and together provide a holistic view of the Sun and the solar wind. This makes us confident that Solar Orbiter will help us answer profound open questions about the Sun.”

No other images of the Sun have been taken from such a close distance. During its first perihelion, the point in the spacecraft’s elliptical orbit closest to the Sun, Solar Orbiter got as close as 77 million kilometres from the star’s surface, about half the distance between the Sun and Earth. The spacecraft will eventually make much closer approaches to the Sun. The spacecraft is now in its cruise phase, gradually adjusting its orbit around the Sun. Once in its science phase, which will commence in late 2021, the spacecraft will get as close as 42 million kilometres from the Sun’s surface, closer than the planet Mercury. The spacecraft’s operators will gradually tilt Solar Orbiter’s orbit to enable the probe to get the first proper view of the Sun’s poles.

A previous spacecraft, Ulysses, flew over the Sun’s poles, but it did it from far away, and was designed not to take images but to study the Sun’s solar wind. Solar Orbiter is getting in close.

Midnight repost: Mars!

11:59 pm

The tenth anniversary retrospective of Behind the Black continues: Despite my many essays on culture and politics, Behind the Black remains mostly a site reporting on space and science. Since the modern exploration of Mars is probably the most significant on-going event now in space, it seemed unsatisfactory to only repost one or two of my past articles on this subject, when I have probably have posted hundreds. Instead, this midnight repost will provide links to a bunch, divided into several topics.

Martian geology, shown in cool images

First, we have the many cool images I have posted on Mars, often tied to detailed descriptions of what scientists are now beginning to learn about the red planet’s mysterious geological history. The following are the most important, and will help readers better understand future cool images.

Future colonization

Next, two posts, both focused on the future exploration and colonization of Mars.

Spring at the Martian South Pole

1:10 pm

Geysers on Mars?
Click for full image.

Geysers on Mars
Click for full image.

It is now full spring at the Martian south pole, and as should be expected much has been happening there. Like the Martian north pole, when sunlight arrives after the dark winter it hits the seasonally-placed mantle or cap of carbon dioxide snow and begins to melt it, in the alien ways things like this occur on Mars.

The two images to the right illustrate this process for one particular place located in what are called the south polar layered deposits. The two images, just released on July 1, 2020 from the high resolution camera on Mars Reconnaissance Orbiter (MRO) and taken on May 14 and May 30 respectively, had immediately caught my attention because they were labeled “Active Geyser Locale Dubbed Macclesfield.” Active geysers?! I immediately contacted Candy Hansen of the Planetary Science Institute in Tucson, Arizona, whom I correctly guessed had requested these photos. She explained,

The name for this site is of course informal, and it dates back to when I first started picking sites to monitor. I was so certain we would see active geysers here! We see their deposits, the fans on the surface, but so far we have not caught an actual eruption in progress.

The overview map of the south pole below provides some context.

Putin gov’t arrests journalist working as advisor to Roscomsos

9:24 am

The Putin government yesterday arrested Ivan Safronov, a former journalist presently an advisor to that country’s space agency Roscosmos, for passing military secrets to the Czech government back in 2017 when he was employed by a daily newspaper.

It seems the press in Russia is highly skeptical of these charges.

Kommersant [the daily newspaper in which he had worked] put out a statement in support of Safronov, hailing him as one of the country’s top journalists and a “true patriot” who was deeply concerned about the state of the military and space industries that he covered. The newspaper described the accusations against him as “absurd.” The paper noted that rights activists, journalists, scientists and corporate officials who faced treason accusations found it difficult to defend themselves because of secrecy surrounding their cases and lack of public access. “As a result, the public has to rely on the narrative offered by special services, whose work has increasingly raised questions,” Kommersant said. “Journalists asking those questions find themselves under blow.”

About 20 journalists, including those who worked with Safronov for years, were detained outside FSB headquarters in Moscow when they picketed to protest his arrest. Some were handed court summons for violating a ban on street gatherings during the coronavirus pandemic, an offense punishable by an administrative fine.

Many former colleagues of Safronov alleged that the authorities may have wanted to take revenge for his reporting that exposed Russian military incidents and opaque arms trade deals.

It also appears that the charges have nothing to do with Safronov’s work at Roscosmos.

NASA completes Starliner review, finds more issues

9:15 am

Capitalism in space: NASA yesterday released the results of its investigation into the issues that prevented Boeing’s manned Starliner capsule from successfully completing its unmanned demo flight to ISS in December, finding an additional 20 issues over the 61 initially identified shortly after the mission.

In closing out the seven-month investigation, NASA officials said Tuesday they have now identified 80 corrective actions, mostly involving software and testing, that must be done before the Starliner capsule launches again. The previous count was 61.

NASA officials also admitted that they had been so focused on making sure SpaceX’s Dragon capsule was going to work that they became lax in reviewing Boeing’s work. Now they not only are going to focus more on Boeing, they actually want to use SpaceX’s approach to software development throughout NASA.

NASA is also borrowing SpaceX’s “robust” approach to software, which involves going back to the designers following testing for feedback, said Kathy Lueders, NASA’s new human spaceflight chief who until a month ago managed commercial crew. She wants to see more of that type of approach across other NASA programs.

Though it seems absurd and incredible that NASA has not been consulting with its designers after testing, it is also not surprising. When it comes to designing and building anything at NASA the management processes there have routinely done a bad job for many years.

As for Starliner, it is expected it will take a few more months to fix these issues, which means the next unmanned test flight is likely still set for sometime in the fall, with the manned mission to follow next spring.

Results from Yutu-2 determine “gel-like” rocks are impact melt

9:04 am

Chinese scientists have now published their analysis of the “gel-like” rocks seen by China’s Yutu-2 lunar rover back in October 2019, and have concluded that they are glasses produced from melt occurring during an impact.

The authors describe the material as a dark greenish and glistening impact melt breccia, measuring 20 inches by 6 inches (52 by 16 centimeters). These features are signs of possible presence of glasses, which are usually sourced from impact melts or from volcanic eruptions.

According to the paper, the breccia — broken fragment of minerals cemented together — was formed by impact-generated welding, cementing and agglutinating of lunar regolith and breccia. The material, they say, resembles lunar impact melt breccia samples returned by NASA’s Apollo missions. In particular, similarities with the Apollo samples designated 15466 and 70019 are noted, a comparison made earlier by lunar scientist Clive Neal at the University of Notre Dame. Sample 70019, collected by astronaut and trained geologist Harrison “Jack” Schmitt, is made of dark, broken fragments of minerals cemented together and black, shiny glass.

The results are not definitive, however. The paper notes that the analysis is limited by the fact that VNIS measurements were taken under bad illumination conditions and other factors.

This conclusion is not surprising, as the rover has been traveling through a region dominated by impact ejecta.

Proposed House NASA budget flat, with some surprising support for Artemis

8:51 am

While the first House proposal for NASA’s 2021 budget has rejected the Trump administration’s request for a total $3 billion increase for the agency to fund Artemis so that it can complete a manned mission to the Moon by 2024, it also provided about 18% of the funds requested for building the manned lunar lander required for that mission.

Back in February, the White House asked for $3.37 billion in fiscal year 2021 to accelerate development of the lander.

Democrats in the House have been skeptical of the 2024 launch date—some see it as political due to the timing of the next presidential election—and so have been slow to fund the lander. In its budget, the House appropriates $1.56 billion for “Exploration Research and Development.” This includes funding for the lander, Lunar Gateway, and other activities related to the Moon’s surface, of which more than $600 million can be used for the lander.

The House also provided a boost of $343 million to SLS.

My guess is that the Democrats in the House are working to keep Artemis going because of the jobs it brings to their districts, but want to slow it down enough so that it cannot succeed while Trump is in office. Thus, the release of some funds for the lunar lander, but not enough to build it, now.

The House proposal also includes a loosening on Congress’s mandate that Europa Clipper must launch on SLS. NASA is now given the option to consider other alternatives if SLS is not avaiable, which means that NASA can now consider using the Falcon Heavy instead.

This proposal must still pass the Republican-controlled Senate, so expect more changes.

InSight’s mole is bouncing again

8:24 am

Plan of action for InSight's mole

The engineering team for InSight’s German-built digging tool, dubbed the mole, yesterday reported that it is once again no longer driving into the ground.

Previously they had been able to make progress by having InSight’s scoop press down on the mole. Once the top of the mole however was below ground, the scoop could no longer provide that support, and at that point the mole began bouncing again with each hammer-stroke, the surrounding Martian dirt unable to provide the friction to hold the mole down.

As shown by the illustration above, they are now going to try using the scoop to fill the hole and then use the scoop to press down on the dirt, with the hope this will provide the structural friction required to hold the mole in place after each hammer stroke. This effort will take time, and will prevent the scoop from doing its other work. They are therefore taking a pause until August before beginning the hole-filling operation.
