Head of NASA’s commercial program picked as chief of manned space

NASA’s administrator Jim Bridenstine yesterday announced that he has chosen Kathy Lueders to be the new head of the agency’s human exploration program.

In her most recent positions at NASA Lueders has been in charge first of the ISS commercial cargo program, followed by the ISS commercial crew program. She now heads the entire manned program, including Artemis.

This appointment appears to be great news for the emerging new commercial space sector (led by SpaceX), as Lueders’ close contact with them for the past half decade or so means she has seen up front the advantages of both competition and private enterprise. I suspect she will not look kindly at the endless delays at SLS and Orion, even if she has to play the political game of publicly appearing to support those projects. Like her predecessor Doug Loverro, she will be open to awarding contracts to whoever can get the job done best, rather than favoring the traditional big space contractors Boeing and Lockheed Martin, as Loverro’s predecessor Bill Gerstenmaier had often done.

NASA’s shift from being the builder of space systems to the buyer of space systems is going to accelerate.

Successful SpaceX launch

Falcon 9 shortly after launch

Capitalism in space: SpaceX tonight successfully launched 58 Starlink satellites as well as three Planet earth observation satellites. The image to the right looks up at the exhaust from the nine firing Merlin engines of Falcon 9 rocket, about two minutes after launch.

That first stage also successfully landed, the third time this stage has completed a launch. The fairing halves were also reused.

The leaders in the 2020 launch race:

11 China
9 SpaceX
7 Russia
3 ULA

The U.S. now leads China 15 to 11 in the national rankings.

Successful Rocket Lab launch

Electron eleven seconds after liftoff

Capitalism in space: Rocket Lab today (June 13 in New Zealand) successfully launched five cubesats into orbit using its Electron rocket. The image to the right was taken eleven seconds after liftoff.

This was Rocket Lab’s second launch in 2020, delayed three months due to the Wuhan flu panic that shut down New Zealand. This does not put them in the leader board, but it does change the national rankings. The leaders in the 2020 launch race:

11 China
8 SpaceX
7 Russia
3 ULA

The U.S. now leads China 14 to 11 among the nations. Since SpaceX has its own Starlink launch later tonight, these numbers will likely change again before the night is over.

Chinese military officer arrested trying to leave U.S.

A Chinese military officer who had been participating in research at the University of California in San Francisco under false pretenses was arrested on June 7th as he was trying leave the country with data and information gathered during his stay.

To obtain a visa, Wang allegedly lied about his affiliation with the Chinese military, claiming his service with the People’s Liberation Army had ended in September 2016. In reality, according to the Justice Department, Wang was still associated with the military, which was paying him a stipend while he was in the U.S.

In May, Wang told his supervisor at the university that he was “being recalled to China by his employer, the Fourth Military Medical University, and that he would not return to work at the UCSF lab, thus cutting his fellowship short by approximately one year,” court documents said. Wang also informed his supervisor that he wanted to collaborate remotely from China and that he had already duplicated some of the research conducted at the California laboratory. Court documents said the duplication of research “was previously unbeknownst” to the supervisor in the U.S.

“Wang was instructed by his supervisor in China, the director of the Fourth Military Medical University lab, to observe and document the layout of the lab at UCSF in order to replicate the lab when he returned to China,” the Justice Department said.

The wisdom of the decision by the Trump administration to restrict entry of any Chinese students with ties to the Chinese military is becoming clearer and clearer.

Seattle fire station to become “community center for black residents”

The return of segregation! The Democratically-controlled city of Seattle has decided to bow to demands from a black supremacy group and give that group control over a fire station, making it a “community center for black residents”.

“We at the City of Seattle understand the urgency behind making bold investments in the Black community and increasing community ownership of land in the Central District,” the city wrote. “The City believes in the vision behind the William Grose Center for Cultural Innovation and we remain committed to making the transfer of Fire Station 6 to the community a reality.”

“We have received Africatown’s list of community requests along with a longer list of asks from other black-led organizations. Deputy Mayor Shefali Ranganathan has already met with the King County Equity Now coalition and, on behalf of Mayor Durkan, she will be working with Seattle Department of Neighborhoods and Seattle Office of Planning and Community Development to work on next steps with the community,” it added.

Based on everything I can gather, this new “community center” will be for blacks only. Gee, wasn’t the whole point of the civil rights movement to no longer exclude people based on their skin color?

No matter. This policy of race-based segregation is merely the Democratic party going back to its roots. The only difference is that, unlike in the past when they favored whites and oppressed blacks, they are now favoring blacks and oppressing whites. Seems like a wonderful reason to vote for them, right, Seattle?

Help scientists plan Curiosity’s future travels

The Curiosity science team is asking the help of ordinary citizens in improving the software it uses to plan Curiosity’s future travels.

Using the online tool AI4Mars to label terrain features in pictures downloaded from the Red Planet, you can train an artificial intelligence algorithm to automatically read the landscape.

Is that a big rock to the left? Could it be sand? Or maybe it’s nice, flat bedrock. AI4Mars, which is hosted on the citizen science website Zooniverse, lets you draw boundaries around terrain and choose one of four labels. Those labels are key to sharpening the Martian terrain-classification algorithm called SPOC (Soil Property and Object Classification).

The goal is not to have citizens plan the rover’s route, but to use their judgments to refine the software that the scientists and engineers use to plan the route. This refinement will also be applicable to Perseverance when it gets to Jezero Crater in February 2021.

Isidis Basin, on whose margin Perseverance will roam

Pedestal craters in Isidis Basin
Click for full image.

Overview map

Today’s cool image to the right, cropped and reduced to post here, highlights the floor of one of Mars’ largest basins, dubbed Isidis Planitia, and located at the transition zone between the planet’s northern lowland plains and the southern cratered highlands.

The overview map below of Isidis Basin provides some context. The white box shows where this particular image is located. Jezero Crater, indicated by the red circle (which is also about the size of the crater), is where the rover Perseverance is going to land and roam come February 2021, should all go well. For scale, Isidis is about the size of the eastern half of the United States. If Chicago was located at Jezero Crater, Baltimore would be on the basin’s eastern edge, at around 4 o’clock.

This particular section of the full photo, taken on April 5, 2020 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), shows many features very typical of the floor of Isidis Basin, which also immediately reveal a great deal about its possible history.

In this small snippet we can see what at first glance appear to be pedestal craters standing up like mesas, with ordinary craters scattered about on that lower surrounding terrain. Clearly, if these are pedestal craters they had to have been created first, and then over a very long time erosion processes ate away at that plain, leaving these pedestals (which had become resistant to erosion because the impact had packed their material together and made it harder) behind as mesas.

Then, after this period of erosion was complete enough additional time was required for at least one or two rounds of cratering to occur, leaving behind the many more younger craters on the plain floor, many of which are now partly buried by dust and sand.

The problem is that these mesas are almost certainly not pedestal craters, despite their appearance. » Read more

New analysis of COVID-19 death rate ranks it the same as “a strong seasonal flu”

A new analysis of the COVID-19 death rate has found that it is really no more dangerous than “a strong seasonal flu”, and that it poses little threat to the general population.

Moreover, the analysis finds that

Up to 30% of all additional deaths may have been caused not by Covid19, but by the effects of the lockdown, panic and fear. For example, the treatment of heart attacks and strokes decreased by up to 60% because many patients no longer dared to go to hospital. Even in so-called “Covid19 deaths” it is often not clear whether they died from or with coronavirus (i.e. from underlying diseases) or if they were counted as “presumed cases” and not tested at all. However, official figures usually do not reflect this distinction.

Read it all. There is lots more, all pointing to the unwarranted nature of the panic over the flu, and how that panic likely caused more deaths and damage. Had we reacted more calmly (as had been done for all past similar new such respiratory diseases), the harm to society and number of deaths would have likely been less.

Marble race

An evening pause: I actually would do this with my marbles as a child. All you needed was a gentle slope and a way to keep the marbles confined within the track. For me, it was a gap between the carpet and one wall in the living room of our rented apartment. The floor just happened to slope just enough.

What is amazing is how you can’t help but pick a marble and cheer for it.

New Horizons sees stellar parallax

New Horizons is now far enough away from Earth that its perspective of the universe shifts at least two nearby stars into slightly different positions than seen on Earth.

On April 22-23, the spacecraft turned its long-range telescopic camera to a pair of the closest stars, Proxima Centauri and Wolf 359, showing just how they appear in different places than we see from Earth. Scientists have long used this “parallax effect” – how a star appears to shift against its background when seen from different locations — to measure distances to stars.

An easy way to see parallax is to place one finger at arm’s length and watch it jump back and forth when you view it successively with each eye. Similarly, as Earth makes it way around the Sun, the stars shift their positions. But because even the nearest stars are hundreds of thousands of times farther away than the diameter of Earth’s orbit, the parallax shifts are tiny, and can only be measured with precise instrumentation. “No human eye can detect these shifts,” Stern said.

But when New Horizons images are paired with pictures of the same stars taken on the same dates by telescopes on Earth, the parallax shift is instantly visible. The combination yields a 3D view of the stars “floating” in front of their background star fields.

The resulting 3D image, available at the link, is very cool. Both stars clearly appear closer than the surrounding background stars, which of course is true as they are among the closest stars to the Sun.

Trump had better do something soon

In Seattle on June 9, 2020 a group of rioters and Antifa and Black Lives Matter radicals took complete control over a seven block wide area of the city, throwing out the police, taking possession of the police station, and declaring the area the Capital Hill Autonomous Zone (CHAZ).

The next day, June 9th, President Donald Trump tweeted the following:

Radical Left Governor @JayInslee and the Mayor of Seattle are being taunted and played at a level that our great Country has never seen before. Take back your city NOW. If you don’t do it, I will. This is not a game. These ugly Anarchists must be stooped (sic) IMMEDIATELY. MOVE FAST!

Not surprisingly the response from the Washington Democratic politicians was contempt and defiance.

Gov. Jay Inslee also fired back at Trump on Twitter, posting, “A man who is totally incapable of governing should stay out of Washington state’s business. ‘Stoop’ tweeting.”

I think their contempt here is justified. Trump, who until the arrival of the Wuhan flu panic this spring had consistently stood up against the bullying and irrational hate of the left, has been played by them badly in the past three months.

NASA IG: Bolden misused NASA resources after leaving agency

According to a new NASA inspector general report released today [pdf], former NASA administrator Charles Bolden improperly used the services of his NASA executive assistant for two years after his resignation, and that misuse included aiding him in building his private consulting firm.

The [inspector general] concluded that the EA [Executive Assistant] inappropriately provided significant administrative assistance to Bolden to include managing his personal and business appointments, making travel arrangements, and coordinating special requests for almost 2 years, from his departure in January 2017 through December 2018. We further found that the EA’s assistance helped facilitate the growth of Bolden’s private consulting business and, as a result, Bolden was able to hire the EA as an employee upon her retirement from NASA in early 2019.

The report is remarkable kind to Bolden, making many attempts to excuse this essentially illegal abuse of government resources for private gain. But then, he is a Democrat who worked for the Democratic Obama administration, and if there is anything we have learned in the past decade, it is that there is an unwritten law in DC that states that no Democrat shall ever be punished for any crimes.

In Bolden’s defense, the report states the following,

Bolden took full responsibility for his actions, offered to provide reimbursement for the services he had received, and recommended that in the future specific guidance be provided to departing senior executives as to what type of administrative support they could expect to receive, if any.

I really wonder if anyone can really assign a number to this work. Moreover, there is no evidence in the report that Bolden has actually reimbursed the agency. Based on past such incidents, I am very doubtful such reimbursement will ever happen. The tactic each time has been to make a loud announcement of contrition, but then when things quiet down to conveniently forget about it.

India’s first manned mission faces delays, caused by COVID-19

The new colonial movement: According to ISRO officials, India’s first manned mission, Gaganyaan, might have to be delayed because of restrictions imposed due to the Wuhan flu panic.

Bengaluru-headquartered ISRO (Indian Space Research Organisation) had earlier said it has planned two trial flights without crew ahead of Gaganyaan — the first one around December 2020 and the second around July 2021.

“…there are some disturbances because of COVID, but still nothing is confirmed (about delay). We need to see, still we have got some six months time. We are trying to see if we can reach there,” a senior ISRO official told P T I. He added: “There may be slight up and down (in the schedule), but that will be known only when we do the complete evaluation…it is premature to say anything, because the team that is working (on the project) has not indicated (about delay).”

The manned flight is presently scheduled for 2022. This might change.

NASA confirms Webb launch delayed again

NASA officials yesterday confirmed that, due to the new work conditions and the lock down imposed by the Wuhan flu panic, the launch of the James Webb Space telescope will not occur in March 2021.

“We will not launch in March,” said Thomas Zurbuchen, the space agency’s associate administrator for science. “Absolutely we will not launch in March. That is not in the cards right now. That’s not because they did anything wrong. It’s not anyone’s fault or mismanagement.”

Zurbuchen made these comments at a virtual meeting of the National Academies’ Space Studies Board. He said the telescope was already cutting it close on its schedule before the COVID-19 pandemic struck the agency and that the virus had led to additional lost work time. “This team has stayed on its toes and pushed this telescope forward at the maximum speed possible,” he said. “But we’ve lost time. Instead of two shifts fully staffed, we could not do that for all the reasons that we talk about. Not everybody was available. There were positive cases here and there (in the surrounding area, not on site). And so, perhaps, we had only one shift.”

No new target date has been set, though the comments even hinted that they might not be able to do it in 2021.

Webb will cost 20 times more than originally budgeted ($500 million vs $10 billion) and is now more than a decade behind schedule. In the process, those overages and delays wiped out almost all of NASA’s other astronomy projects during the 2010s.

But don’t worry! Once Webb launches the task of wiping out more astronomy projects with overages and delays will be courageously taken up by NASA’s Roman Space Telescope (formerly WFIRST), already behind schedule and over budget, and it is still only in the design phase.

Astrobotic wins contract to land VIPER rover at Moon’s south pole

Capitalism in space: NASA today awarded the private company Astrobotic a $199 million contract to provide the lander that place place the agency’s VIPER rover down near Moon’s south pole.

The target date for the mission is late 2023, and is intended as a scouting mission for the Artemis manned landing to follow.

During its 100-Earth-day mission, the approximately 1,000-pound VIPER rover will roam several miles and use its four science instruments to sample various soil environments. Versions of its three water-hunting instruments are flying to the Moon on earlier CLPS lander deliveries in 2021 and 2022 to help test their performance on the lunar surface prior to VIPER’s mission. The rover also will have a drill to bore approximately 3 feet into the lunar surface.

The key to this mission continues to be NASA’s shift from building things to hiring others to build them. If Astrobotic is successfully, they will then be positioned to offer their lander design to others, since it belongs to them, not NASA.

Chinese launch and Rocket Lab scrub

Electron on launchpad, June 11, 2020

Yesterday China used its Long March 2C rocket to launch an ocean observation satellite, while also testing both grid fins and a revamped fairing. The goal of the grid fins is to control the first stage’s return to Earth so that it won’t crash on top of any homes. The fairing change is to hopefully lead to their capture and reuse sometime in the future.

Late today, or actually early on June 11th, Rocket Lab tried to do its twelve commercial launch, but after three launch tries the high winds won out and they had to scrub. The image to the right shows the Electron rocket on the launchpad. If you look close, you can see the wind whipping the LOX evaporating off the rocket.

The leaders in the 2020 launch race:

11 China
8 SpaceX
7 Russia
3 ULA

The U.S. continues to lead China 13 to 11 in the national rankings.

Kodo – O-Daiko

An evening pause: Japanese drummers playing the Ōdaiko drum

Ōdaiko : One of the most memorable drums of many taiko ensembles is the ōdaiko (大太鼓). For many, the ōdaiko solo is the embodiment of power due to the size of the drum, the volume, and the endurance it takes to perform. The ōdaiko is the largest drum of all taiko, if not the entire world. The largest ōdaiko are too big to move and permanently reside inside a temple or shrine. Ōdaiko means “big taiko”, but within any group, it describes the largest drum in an ensemble, which could mean 12 inches (300 mm) in diameter or 12 feet (3.7 m) in diameter. Made from a single piece of wood, some ōdaiko come from trees that are hundreds of years old.

Fading Martian slope streaks

Fading Martian slope streaks
Click for full image.

Cool image time! I’ve covered the topic of the mysterious slope streaks on Mars previously in great detail (see here and here). Essentially they are generally dark streaks (but sometimes light) that appear randomly on slopes and then fade over time. Unlike recurring slope lineae, another changing streak found on Martian slopes, the coming and going of slope streaks is not tied to the seasons. They can appear at any time in the year, and will take several Martian years to fade away.

The image to the right, rotated, cropped, and reduced to post here, was taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) on March 26, 2020. It shows numerous slope streaks down the eastern interior rim of a crater in the transition zone between the northern lowlands and the southern cratered highlands in a region dubbed Arabia Terra.

Though I can find no previous high resolution image of this crater to measure any temporal changes, you can clearly see that this slope has experienced many streaks over time, with some darker than others. The different shades suggest that the lighter streaks are older and have faded, with the darker streaks more recent events.

At the moment there is no strong consensus on the causes of these streaks. As one science paper noted, “The processes that form slope streaks remain obscure. No proposed mechanism readily accounts for all of their observed characteristics and peculiarities.” We know they occur in equatorial regions and dusty locations, and that they are triggered by some disturbance at the topmost point of the streak, which then causes a chain reaction down the slope. Other than that, the facts are puzzling, and suggest that these streaks are a phenomenon wholly unique to Mars.

The crater itself, located at 24 degrees north latitude, has some other mysteries. The features on its floor, for instance, are very puzzling. Though suggestive of the buried glaciers found in many craters in the mid-latitudes, this crater is a bit too far south. Maybe its higher altitude allows for some ice to remain here? Then again, the features on that floor might have nothing to do with ice. Maybe we are looking at sand carved by wind? Or hardened mud that was once wet?

I am merely guessing, a dangerous thing to do when one’s knowledge is limited. Then again, it’s fun, so please join in with your own guesses.
