Ryugu’s most primitive boulders

1:18 pm

In a just published paper scientists reveal how they think they have identified the oldest rocks on the rubble pile asteroid Ryugu, and found them to be distributed across the entire face of the asteroid.

These boulders are light enough that they would float on water.

Ryugu is thought to have initially formed as a fluffy planetesimal that coalesced from accumulated dust in the early Solar System, and subsequently underwent processes such as thermal evolution and compression. This parent body was then later destroyed in a collision and fragments of this reaccumulated into the asteroid. However, planetesimals have never been seen, so whether they really existed or what they may have looked like is one of the biggest challenges in understanding the planet formation process. The boulders discovered in this research are thought to be a material that most strongly retains the appearance of the fluffy planetesimals that triggered the birth of the planets in the Solar System.

Additionally, the data from all the scientific instruments onboard Hayabusa2 that were used to examine the surface of Ryugu revealed that fragments of material similar to those of the ultra-high porosity boulders are globally distributed over the asteroid surface, and may have been collected in the sample taken by Hayabusa2. If highly primitive material with the ultra-high porosity discovered here is also found in the collected samples, it will both clarify the formation and evolutional history of Ryugu’s parent body, and also provide evidence of planetesimal formation in the early stage of the Solar System formation process.

There is no word yet from the scientists studying the Hayabusa-2 samples on what they have found. This paper gives them an idea of what could be the most important type of rock to look for.

Today’s blacklisted American: All conservatives on Facebook

12:59 pm

The Bill of Rights cancelled at Facebook and Instagram
No first amendment on Facebook.

The new dark age of silencing: It isn’t really news to post an article describing the effort at Facebook to silence and squelch conservative thought. I along with many others have already done so repeatedly, with the worst and most blatant banning beginning with the wave of censorship that these big social media sites initiated just after January 6th. Nor has Facebook eased up in subsequent months. For example, in April Facebook blackballed a mother for daring to criticize the radical Marxist and racist policies of her school board.

Since then, Facebook has shut down a pro-Israel Christian site with 77 million followers and blocked the viewing of reviews of a climate book by former Obama science advisor Steve Koonin that raised doubts about the theory of human-caused climate change.

In the former case, it appears that Facebook allowed itself to be influenced by a orchestrated attack by radical Islamic organizations, which posted more than a million comments of complaint to the site in an effort to get it canceled. Facebook of course complied.

In the latter case Facebook took on faith the complaints made by pro-global warming websites, which claimed that the book was false simply because it disagreed with those pro-global warming sites. None of them actually cited any incorrect facts put forth by the reviewed book. And even if they had found errors and falsehoods, the right answer to bad speech is never censorship, but an educated response.

Facebook claims that this censorship campaign is not really aimed at any particular political point of view, but is instead designed to reduce the overall political content on Facebook. And yet, their own description of their effort illustrates its partisan nature:

The big cliffs of Gediz Vallis on Mars

11:33 am

The Big Cliffs of Mt Sharp
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken on May 21, 2021 by Curiosity’s chemistry camera (ChemCam), normally designed to look at high resolution close-up imagery of nearby objects.

However, it can also be used as what the science team call “a long distance spyglass.” The image to the right is an example, looking at what I think are the distant but steadily approaching big cliffs on the western wall of the canyon Gediz Vallis. Make sure you look close at the shadowed cliff-face, probably several hundred feet high. It is filled with huge rock faces reminiscent of the most stark rock cliffs on the mountains of Earth.

The two images below provide the context, which makes the image even more quite breath-taking.

The arrival of routine flights of commercial space passengers to orbit now makes the meaning of the word “astronaut” very unclear

9:45 am

Link here. Up to now the word “astronaut” has generally been applied to anyone who has flown in space, though its use for the previous space tourists has generally seemed inappropriate.

The arrival this fall of regularly and frequent commercial flights carrying private passengers into space raises the question: What do we call these individuals? Some, such as the companies Axiom and Blue Origin, want to call them astronauts. Others, such as previous space tourists Richard Garriott and former senator and now NASA administrator Bill Nelson, think that word should be reserved for the professionals. Think for example of aviation. You don’t get wings by simply flying on a commercial jet. You have to fly a plane yourself, and do it solo to earn that designation.

In truth, the most likely thing that will happen in the future is that no future space traveler will be called an astronaut. As the article notes correctly,

It might be necessary to retire the term altogether once hundreds if not thousands reach space, noted Fordham University history professor Asif Siddiqi, the author of several space books. “Are we going to call each and every one of them astronauts?”

The term is going to become historical, referring not to those who have reached space, but to those early pioneers to made it possible for everyone else. It carries too much special meaning to assign it to every Tom, Dick, or Harry who simply bought a ticket. It signifies a person who did something special and at great risk, and deserves a special honor because of it.

Neil Armstrong and Yuri Gagarin were astronauts. It seems wrong to call every commercial passenger who follows the same.

Bernie Sanders throws a wrench into Senate bill forcing NASA to award two lunar lander contracts

9:18 am

Capitalism in space? Senator Bernie Sanders (Socialist/Democrat-Vermont) has submitted a new amendment to the new NASA authorization bill, now being debated in the Senate, that eliminates the earlier changes added by senator Maria Cantwell (D-Washington) that required NASA to award a contract to a second company for building its manned lunar lander.

This earlier amendment, submitted by Sen. Maria Cantwell (D-Wash.), modified NASA’s Artemis Program. Cantwell’s amendment, in part, called for $10.03 billion in additional funding for NASA to carry out the Human Landing System program. This legislation was filed as Blue Origin and Jeff Bezos were urging Congress to add $10 billion to NASA’s budget—enough money to fully fund the development of a second Human Landing System. It was passed 11 days ago without any debate by the US Senate Committee on Commerce, Science, and Transportation.

Sanders’ terse amendment seeks to excise the Cantwell language that provides additional funding for a Human Landing System.

While Sanders’ amendment probably makes more sense based on the money that Congress has actually appropriated for this task, he didn’t do it for that reason. More likely he did it as a petty attack on Jeff Bezos, whose company Blue Origin was likely expected to win that second contract.

Nothing is settled yet of course. The bill still has to pass the Senate and also be approved by the House, then signed by the president. Much will change before then.

Regardless, isn’t nice how NASA’s modern space effort is so well designed by our senators and congressmen? What would we do without them?

A detailed review of Virgin Galactic

9:03 am

Link here. The article not only provides a thorough review of the company’s most recent test flight and what it did and did not accomplish, it takes a look backward to reevaluate Virgin Galactic’s history, including the many engineering problems in the past few years that have slowed development and risked lives.

The most shocking aspect of this story is this fact:

The fact that VSS Unity was broken was never disclosed to Social Capital shareholders who approved the merger, or to investors who bought the stock after the merged companies went public under Virgin Galactic’s name on the New York Stock Exchange on Oct. 28, 2019.

The source who revealed the near-fatal February 2019 flight to Parabolic Arc questioned whether withholding that information from shareholders was legal under securities laws. A number of law firms have launched investigations into Virgin Galactic recently. Their primary focus seems to be the steep drop in the company’s stock price earlier this year. (It has rebounded sharply since the flight test.) But, perhaps they will carefully review the company’s public disclosures regarding the condition of VSS Unity.

In reviewing the building competition between Virgin Galactic and Blue Origin to fly the first commercial passengers, the article also confirms many of the same observations I have made about both companies.

Read it all. It shines light beyond the pr blather that you will get from most modern media as they rewrite press releases.

Folded ballots caused many (but not all) of the tabulator errors in New Hampshire vote

3:31 pm

The auditors of the Windham, New Hampshire, local vote have determined that folded ballots caused many of the false totals produced by the computer tabulators.

Auditors said they found “experimental confirmation that if the contest is undervoted, a fold through a vote target can create a vote.”

“Something we strongly suspect at this juncture, based on various evidence, is that in some cases, fold lines are being interpreted by the scanners as valid votes,” Mark Lindeman, who is part of the audit team, told WMUR.

Harri Hursti, another auditor, wrote on Twitter that testing proved folded ballots were misinterpreted by machines. “Test decks proved that foldings across a vote targets is misinterpreted as additional phantom votes or subtracts votes due to false overvotes,” he wrote in a post.

Their testing however has shown that folded ballots are not the only cause of the untrustworthy tabulations.

Another machine was found to have “an even more dramatic problem” by the auditors, who said that only 28 percent of the votes for Republican candidates were counted.

The machines were apparently provided by a company called AccuVote, but the “machines’ intellectual property is owned by Dominion Voting Systems.”

The results here prove that these tabulator machines are totally untrustworthy, and should be junked entirely, with the state having a legitimate case for suing the companies involved for failure to deliver.

At the least. The research so far has found that the bulk of the errors routinely seem to penalize Republicans. If further research reveals that this partisan slant is not an accident, then criminal charges might very well be in order.

GAO finds more NASA cost overruns in Webb, SLS, and Orion

2:18 pm

GAO graph documenting NASA's big project delays and cost overruns

The annual Government Accountability Office’s (GAO) report on major NASA-led programs has found that the cost overruns and scheduling problems it has documented now for years continued in 2020.

You can obtain the report here. The graph to the left, from the report, summarizes the data quite succinctly.

The cumulative cost overrun of 20 major programs in development, defined as those with total costs of at least $250 million, grew to more than $9.6 billion in the report. Three programs — the James Webb Space Telescope, Orion spacecraft and Space Launch System — account for $8 billion of that total, including $4.4 billion for JWST alone.

SLS and the Exploration Ground Systems program accounted for effectively all of the $1.1 billion in overruns in 2020. … SLS alone accounted for nearly $990 million in cost increases. About two-thirds of that increase came from NASA adopting a GAO recommendation to lower the original baseline cost estimate for SLS to properly account for work that had been shifted to later phases of the program.

The report also documented almost 20 years of cumulative delays, with Webb leading the way with delays of more than seven years. The new report added 37 more months of delays during the last year.

The report, and NASA, laid the blame for many of the more recent delays and cost overruns on last year’s COVID epidemic, but if so those delays were imposed by choice, not necessity, considering how both China and SpaceX moved forward without any delays during the same time period. In reporting on NASA for the last three decades I have found it willing to initiate long delays at the drop of a hat, sometimes for reasons, such as a storm that causes some minor damage, that do not justify either the delay or its length. The COVID panic was just another example of this.

Today’s blacklisted American: Tenured professor objects to segregated-by-race training classes at university; school investigates and punishes her

Today's modern witch hunt
Burning witches: What the Lake Washington Institute of
Technology wants to do to anyone who expresses an
original and independent thought

They’re coming for you next: Because a tenured professor, Elisa Parrett, made a four minute statement objecting to the segregated-by-race training class the Lake Washington Institute of Technology was mandating for its teachers, the school instigated a nine month investigation resulting in a reprimand and rules forbidding her to speak on such topics again.

The investigation included the hiring of a private investigator, numerous interviews, public humiliation, and wild unsubstantiated claims that her remarks caused widespread trauma. The school removed her from her teaching duties, and worse, doubled down on its insistence that future sessions will be segregated by race. From the university’s president Amy Morrison:

Sierra Space signs up its first customer for its commercial space station

9:11 am

Capitalism in space: Sierra Space, the newly created space division of Sierra Nevada, announced last week that it has signed an agreement with Redwire, formerly known as Made in Space, to establish manufacturing facilities on its LIFE private space station.

The press release is vague about details, being mostly a sales pitch for encouraging other in-space manufacturing companies to consider partnering with Sierra. This in turn suggests the agreement is nothing more that a statement by Redwire that should Sierra’s station launch, it will then be willing to launch its 3D printing technology to it.

Nonetheless, this agreement lends weight to Sierra’s station proposal, which while plausible still remains somewhat vague as there is no indication on when the company plans to launch it.

Zhurong rolls onto Martian surface

10:39 am

Zhurong's view of lander after deployment onto Martian surface

The new colonial movement: According to China’s state-run press, the Zhurong rover has successfully rolled off its lander and reached the Martian surface.

The image to the right was taken by the rover’s rear hazard avoidance camera, and shows the lander and the deployment ramps behind Zhurong.

At this moment China has released no other images of the Martian surface, nor have they revealed if they have a precise idea of where the lander actually put down on Mars. This latter information is essential for them to plan the rover’s travels over its 90-day nominal mission.

Nonetheless, it appears Zhurong is functioning perfectly. If all goes right, it will not only complete that 90-day mission but continue on for considerably longer, as have other similar small rovers on both Mars and the Moon.

Virgin Galactic finally makes manned flight from New Mexico

10:30 am

Capitalism in space: More than a decade later than initially promised, Virgin Galactic today finally made its first successful manned flight from Spaceport America in New Mexico.

The flight apparently reached 55 miles altitude before returning to Earth.

This was the first flight of VSS Unity since December 12, 2020, when the flight was aborted just one second after separating from its carrier airplane, WhiteKnightTwo, when a computer disconnected unexpectedly. Further delays followed:

The problems didn’t stop there, as in early May, a new issue crept up as a post-flight inspection of VMS Eve called for further engineering analysis to assess a known problem in the tail of the vehicle which was to be addressed during the next scheduled maintenance period. The company says that they have completed the analysis and determined that the structures are healthy and cleared Eve for flight.

Their plans are to do one more test flight, and then a “commercial” flight carrying company founder Richard Branson. Following that they will begin selling and flying tourists.

It appears however that they will have lost the race to fly the first suborbital tourist in space, as it appears that Blue Origin’s July 20th commercial flight will happen first.

Election audit in New Hampshire confirms unreliability of machine tabulators

3:49 pm

Auditors today completed a hand recount of the votes in the town of Windham, New Hampshire and concluded that the count proves the machine tabulators are unreliable and do not produce trustworthy totals.

Hand recount finished & #’s very closely match the hand recount #’s done on Nov 12. Windham voting machine election results are confirmed to be unreliable. @WAuditors still investigating causes & contributing factors.

None of the local results are changed because of these new results, but the audit was done because a hand recount done in November showed serious discrepancies, with the hand count consistently finding more votes for Republicans compared to what was tabulated by the machines.

On Election Night, Republicans swept all four of Windham’s state representative seats. One Democrat, Kristi St. Laurent, fell short by just 24 votes and requested a recount.

But during the recount, the margin between St. Laurent and the Republican candidates changed significantly. The vote totals for all of the Republican candidates in the race increased by about 300, while St. Laurent’s vote count decreased by nearly 100.

While the outcome of the race didn’t change — the four Republican victories from Election Day were upheld at the recount — the change in vote totals raised serious questions for many from both parties.

The audit has now confirmed what the hand count has suggested. Both matched closely, but differed significantly from the machine totals, the numbers of which apparently penalized Republican candidates consistently.

They are now beginning an investigation into what caused the discrepancies. I would say above all the town should dump these machines and replace them with something that can be trusted, even if it means we go back to primitive times and hand count all elections.

Curiosity as seen by MRO from orbit
Click for full image.

Today’s cool image, to the right and cropped to post here, was taken on April 18, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Released today by MRO’s science team, it shows the rover Curiosity sitting on top of the 20-foot high rock outcrop the scientists have dubbed Mt. Mercou. The 16,400 foot high Mt. Sharp is to the south, with the rim of Gale Crater about 30 miles to the north.

I have annotated the image to show the rover’s route both before and after the moment when this picture was taken. As the caption at the link notes, the rover is currently working its way up Mt. Mercou, a route that was not initially in their plans, as shown by the wider MRO view below.

Today’s blacklisted American: Professor fired for reading anti-slavery novel to students

12:36 pm

Today's modern witch hunt
Burning witches: What St. John’s university wished it could do
to a Jewish professor.

They’re coming for you next: Hannah Berliner Fischthal, a professor at St. John’s University in New York and the daughter of Holocaust survivors, was immediately fired because she read aloud in her literature class a selection from Mark Twain’s anti-slavery book, Pudd’nhead Wilson, that included the “N-word”.

On March 3 she was called into a meeting with HR about her use of the N-word in class, the subsequent discussion of it and a comment she allegedly made about a Black student’s hair. Fischthal said she only made a remark about a student’s head being wrapped up during class and it had nothing to do with her hair.

She said she was also criticized for mentioning her family’s experience in the Holocaust during class.

On March 5 she was suspended pending an investigation she had violated the university’s policy against bias. On April 29 she was fired.

The school had been alerted to her terrible crime of reading accurately from an accurate book portraying the actual culture of the pre-Civil War south by at least one of her students, who apparently was so weak-minded that even hearing this word that-shall-not-be-named was ““unnecessary and very painful.” It didn’t matter to this brainless student that the book was written to condemn slavery and bigotry. All that mattered is that a word of six letters was spoken aloud and she or he was forced to hear it.

ESA proposes constellation of lunar communications and navigation satellites

11:15 am

The European Space Agency is proposing in this decade to build a constellation of communications and GPS-type satellites, dubbed Moonlight, to orbit the Moon.

ESA is asking two industrial consortia in Europe to define what an integrated sat-nav and telecoms system at the Moon would look like.

It’ll include a constellation of at least three, but probably more, positioning-and-relay satellites to give global coverage, and will likely include some surface beacons, too, to augment the accuracy of the navigation signals.

“The target we have at the moment is that the constellation would be able to allow for an accuracy of 100m and probably better. We think we are able to get to 30m in the first instance,” explained Paul Verhoef, the director of ESA’s navigation department.

The two consortiums are the UK’s Surrey Satellite and Italy’s Telespazio.

It also appears the ESA is proposing making this system available to all lunar exploration missions, whether they be part of the U.S.’s Artemis program or China’s lunar plans. If so, it is commercially smart, as they will have plenty of customers to buy their services.

Delays force ULA to replace Vulcan rocket with Atlas 5 on military launch

11:08 am

Because the development of ULA’s new Vulcan rocket is behind schedule, the Space Force has agreed to allow the company to replace it with an Atlas 5 rocket on a ’22 launch.

That mission, known as USSF-51, was awarded to ULA in August 2020 and is scheduled to launch in late 2022. The company had bid its newly developed Vulcan to fly that mission but the vehicle is not going to be ready on time. As a result, the Space Force agreed to allow ULA to launch USSF-51 on the company’s legacy vehicle the Atlas 5.

…Switching vehicles financially penalizes ULA. According to the company, the Atlas 5 is more expensive than Vulcan. Phase 2 provisions allow ULA to change vehicles but at no cost penalty to the government.

This story however is important because of what it tells us about the state of Blue Origin’s BE-4 rocket engine, required by both Vulcan and Blue Origin’s New Glenn rocket.

At this moment ULA is saying that the first launch of Vulcan is still scheduled for late this year, launching Astrobotic’s Peregrine lander to the Moon. However, for that launch to happen the rocket requires working BE-4 rocket engines for its first stage. In January Blue Origin announced it had finally completed a full throttle test of that engine after problems lasting several years, and would soon be delivering flight-worthy engines to ULA.

It is now late May, and the article at the link revealed this very significant and somewhat shocking detail buried in the text:

Blue Origin in 2020 delivered pathfinder engines for ground tests but has yet to provide a flight-qualified engine for Vulcan’s first flight. A spokeswoman for Blue Origin said May 20 the company is “on track to deliver BE-4 engines this year.” [emphasis mine]

It seems completely impossible for ULA to launch that lunar lander on Vulcan this year if it does not yet have any flight-worthy engines on hand to incorporate and test in the rocket. Worse, it appears that Blue Origin might not deliver those engines for months yet.

This story thus suggests that we will not see launches of either ULA’s new Vulcan rocket or Blue Origin’s New Glenn rocket for a considerable time.

China scrubs launch of station cargo freighter again

10:43 am

For the second time in two days China has scrubbed the launch of the first unmanned Tianzhou cargo freighter to the core module of its space station,

As before, the Chinese only said that the scrub was due to unstated “technical issues.”

They will likely try again tomorrow, but that is pure speculation. Without a more detailed report from China, we really have no idea what is happening.

SpaceX grabbing 90% of the launch contracts to the Moon

10:37 am

Capitalism in space: The announcement yesterday by Firefly that it has awarded SpaceX the launch contract for its Blue Ghost lunar lander mission (scheduled for launch in ’23) is significant because it continues a remarkable pattern of dominance by SpaceX of the lunar launch market.

Right now, of the seven scheduled robot missions to the Moon, SpaceX will launch all but one. The full list, in no particular order:

In addition, SpaceX launched Israel’s Beresheet lander in 2019 on a Falcon 9.

Furthermore, SpaceX has won the contract from NASA for the agency’s first manned lunar lander, using Starship. It has also won the contract to launch the initial components of NASA’s Lunar Gateway space station on a Falcon Heavy.

There are other lunar missions in the works (by Russia, China, and others), but these are all the launches awarded as commercial contracts to private rocket companies in recent years. Thus, of these ten lunar missions, SpaceX has launched or is launching nine. That’s a 90% market share!

The steep sudden foothill of Olympus Mons

2:27 pm

Olympus Mons on Mars

Today’s cool image starts from afar and zooms inward. The elevation map to the right shows Olympus Mons, the largest volcano on Mars and in fact the entire solar system. About 600 miles across, from the edge to its peak this volcano rises about 54,000 feet, with an actual height relative to Mars’ “sea level” of just under 70,000 feet, more than twice as high as Mount Everest on Earth.

The cross-section of this volcano is so large it would cover almost all of France if placed on Earth. As a shield volcano, it was formed by many many volcano flows that laid down many layers of lava, with some in its northwest quadrant thought to be as recent as 2 to 115 million years ago.

Our cool image today is located at the white rectangle at the southeast edge of this volcano, and illustrates how those many lava flows could create such a large shield volcano with such a large cross section.

China scrubs launch of Tianzhou freighter to its Tianhe station module

12:24 pm

The first launch of a Tianzhou freighter to China’s first module, dubbed Tianhe, of its planned Chinese Space Station (CSS), was scrubbed early this morning for unstated “technical reasons.”

Not only has China’s state-run press or its space agency not revealed what caused the scrub, they have said nothing about a new launch date. This cargo freighter however apparently needs to be in place before the arrival of the station’s first crew, now roughly scheduled for sometime in June.

SpaceX begins stacking Superheavy prototype for flight

12:06 pm

Capitalism in space: It appears that the third Superheavy prototype, BN3 (Booster #3), is now being stacked and prepared for the first near-orbital flight of Starship, which SpaceX is still hoping to launch before the end of this year.

SpaceX has at least six BN3 sections – amounting to 22 rings and two of three tank domes – either completed or awaiting integration. The process of stacking BN3 began sometime in the last 7-10 days when SpaceX joined two four-ring sections – including the booster’s common dome, likely pictured above.

SpaceX has mostly completed BN3’s engine section, including a thrust dome with plumbing cutouts for a full 28 Raptor engines. Most recently, what looks like a Super Heavy fuel manifold appeared in Boca Chica. That manifold will attach to the end of a supersized Super Heavy transfer tube – also spotted in work – used to route methane through the liquid oxygen tank to fuel its Raptor engines. Fueling 28 large, high-performance Raptors is no mean feat and requires a rat’s nest of plumbing to feed them more than 15 metric tons (~30,000 lb) of propellant every second at full throttle.

Put simply, a majority of Super Heavy booster BN3’s hardware appears to be ready or almost ready for integration. The eight rings now stacked represent approximately 20% of the rocket’s full height, leaving another 30 or so rings – 54m (~180 ft) – to go.

That flight, the flight plan of which has already been submitted to the FCC, would take off from Boca Chica, circle about three-quarters of the globe, and land in the Pacific to the northwest of Hawaii. While not a full orbit, this flight would demonstrate an orbital capability while allowing for a controlled safe re-entry at a planned location, a wise approach for that first orbital attempt.

Today’s blacklisted American: Former Trump official Sebastian Gorka

11:42 am

The Bill of Rights cancelled at Facebook and Instagram
Does not exist at Google or YouTube.

They’re coming for you next: Along with all other former Trump officials being blackballed by today’s dominant leftist culture, former Trump deputy assistant Sebastian Gorka has found himself banished, first from Fox News, and then from Google’s YouTube.

While Gorka’s problems at YouTube were in the past related to copyright disputes, the final ban last month was simply part of that site’s effort to censor any legitimate discussion of election fraud during the November 2020 election. From their own spokesman:

“In accordance with our long standing strikes system, we terminated the channel America First with Sebastian Gorka, for repeated violations of our presidential election integrity policy,” Ivy Choi, a YouTube spokesperson, wrote in an email to The Hill. … “As we’ve publicly shared, our presidential election integrity policy prohibits content uploaded after last year’s safe harbor deadline that alleges widespread fraud or errors changed the outcome of the 2020 U.S. presidential election,” Choi wrote. “Any channel that violates this policy will receive a strike and channels that receive three strikes in the same 90-day period are permanently removed from YouTube, as in the case of America First with Sebastian Gorka.”

Parker makes course correction

9:25 am

On May 15th the Parker Solar Probe made the first of three small adjustments to its orbital path in order to refine its path during an October 16th fly-by of Venus, which in turn will make more precise its next three Venus fly-bys and thus bring it closer and closer to the Sun.

[The] Parker Solar Probe just completed its eighth close approach to the Sun, coming within a record 6.5 million miles (10.4 million kilometers) of the Sun’s surface on April 29. It’ll pass the Sun from about the same distance again on Aug. 9, before using Venus’ gravity on Oct. 16 to swing it even closer to the surface — about 5.6 million miles (9 million kilometers) — on Nov. 21. Assisted by the remaining three Venus flybys, Parker Solar Probe will eventually come within 4 million miles (6.4 million kilometers) of the solar surface.

The spacecraft remains healthy and continues to gather data with each fly-by of the both the Sun and Venus.

Ingenuity to make sixth flight next week

9:17 am

Future travels for Perseverance and Ingenuity

The Ingenuity engineering team announced today that the Mars helicopter will make its sixth flight next week, flying to a new landing spot while taking images for the Perseverance science team.

Ingenuity’s flight plan begins with the helicopter ascending to 33 feet (10 meters), then heading southwest for about 492 feet (150 meters). When it achieves that distance, the rotorcraft will begin acquiring color imagery of an area of interest as it translates to the south about 50-66 feet (15-20 meters). Stereo imagery of the sand ripples and outcrops of bright rocks at the site will help demonstrate the value of an aerial perspective for future missions. After completing its image collection, Ingenuity will fly about 164 feet (50 meters) northeast where it will touch down at its new base of operations (known as “Field C”).

The flight will attempt a new speed record of 9 mph, and will also land for the first time in a spot that the helicopter has not scouted beforehand. It will instead be using data from high resolution images from Mars Reconnaissance Orbiter (MRO) combined with its own hazard avoidance system.

Ingenuity will essentially place itself over and in an area where Perseverance plans to go, leapfrogging ahead flight by flight, as shown by the map above (annotated by me from the map available here). The green dot numbered 5 shows the helicopter’s present position, while #6 shows its approximate landing spot after its sixth flight. Perseverance, whose present location is indicated by the blue marker, is generally heading south within the area outlined by the red line, as described during the science team’s an April 30th press conference. The goal in exploring this region is to gain a very robust geological baseline of the floor of Jezero Crater, which scientists believe will be the oldest material the rover should see in its travels.

Bidding for ticket on first New Shepard manned suborbital flight reaches $2.8 million

8:37 am

Capitalism in space: The first phase in Blue Origin’s auction for the purchase of the first seat on its New Shepard suborbital spacecraft in July has closed, with the high bid now $2.8 million.

Amazon CEO Jeff Bezos’ Blue Origin space venture has begun unsealing the bids for an open seat on its New Shepard suborbital spaceship, and the high bid hit the $2.8 million mark with more than three weeks to go in the online auction.

Blue Origin says the auction has drawn out more than 5,200 bidders from 136 countries. … Bidding started on May 5 and will conclude with a live auction on June 12. Proceeds from the sale will be donated to Blue Origin’s educational foundation, the Club for the Future.

The first phrase involved sealed secret bids, and ended with the high bid at $1.4 million. The second phase, on-going now with bidding quite brisk, makes the high bid visible to all bidders.

The $2.8 million bid is far higher than the estimated price point predicted for this suborbital flight, which had been in the range of several hundred thousand dollars. The high price is likely because this will be the first flight, and people with cash are willing to spend it to get bragging rights to that seat. At the same time, the high bidding suggests that the previous estimated ticket price might have been low, at least for the first flights.

With three weeks left before the final live auction on June 12th, there is a chance the winning bid could get even higher.

Typical but still mysterious gullies in a crater on Mars

1:40 pm

Gullies on crater interior wall

Today’s cool image to the right, cropped and reduced to post here, is of a crater in the mid-latitudes of Mars’s cratered southern highlands. The picture was taken on January 4, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and is actually the only high resolution image ever taken of this crater.

The gullies in the north interior wall of this crater are the reason why this picture was snapped. These gullies are very typical on the pole-facing slopes of mid-latitude Martian craters, and have puzzled scientists since they were first discovered in the late 1990s in images taken by Mars Global Surveyor. Since then, thousands have been found, almost all of which in the 30 to 60 degree mid-latitude bands where glacial features are also found. Most occur on the more shadowed pole-facing interior slopes of the craters, though at higher latitudes they are also found facing the equator.

Since their discovery scientists have puzzled over their cause, which because of their locations favoring colder temperatures suggest some form of seasonal weather factor. The most preferred hypotheses propose some interaction with water ice or dry ice, or are simply dry flows of rocky granular material. None of these hypotheses have been confirmed. Some evidence suggests they are dry flows, no water involved. Other evidence points to the influence of an underground layer of water ice.

The mystery of these gullies is enhanced by by the wider view from MRO’s context camera below, rotated and cropped to post here.

Today’s blacklisted American: Long-time scholar banned for questioning gender fluidity

11:54 am

Lysenko with Stalin
Trofim Lysenko, the APA’s new hero, preaching to Stalin as he
destroyed Soviet plant research, persecuted anyone
who disagreed with him, and caused famines that killed millions.

They’re coming for you next: John Staddon, a retired and well-published scholar and researcher, was banned from an email discussion group run by the American Psychological Association (APA) for daring to question the modern leftist concept that one can chose one’s sex.

Staddon was deleted from the listserv for allegedly violating the division’s code of conduct. “The division leadership has received complaints about some of the posts that you have sent to the division listserv,” wrote Jonathon Crystal, an Indiana University Bloomington provost and professor of psychological and brain sciences, on behalf of the division’s executive committee.

“I do not want to get into the particulars of the range of complaints over the years, but I will note that a number of members of the executive committee and others have voiced concerns publicly on the listserv in an attempt to make you aware of how readers of the list might view some of the posts,” Crystal wrote. “The executive committee views the use of the division listserv as a privilege and has voted to remove you from the listserv. I am writing to inform you that your email address has been removed from the listserv,” Crystal wrote, adding Staddon can use “other outlets to share your views.”

And what was Staddon’s evil conduct? This is what he had written:
