Report: Reduce contamination restrictions for some future Mars missions

A new policy paper from the National Academies has proposed reducing the planetary protection rules for some future Mars missions, concluding that Earth life cannot survive on Mars for long, and as long as a lander or rover does not land close to cave entrances or on extensive ice, the need to decontaminate is significantly reduced. From the press release:

In this report, the Committee focused on regions on Mars that might not be negatively impacted if visited by spacecraft that are not stringently sterilized. For missions that do not access the subsurface, such regions could include a significant portion of the surface of Mars, because the UV environment is so biocidal that terrestrial organisms are, in most cases, not likely to survive more than one to two sols, or Martian days. For missions that access the subsurface (down to 1 meter), regions on Mars expected to have patchy or no water ice below the surface might also be visited by spacecraft more relaxed bioburden requirements, because such patchy ice is likely not conducive to the proliferation of terrestrial microorganisms.

The report finds that it is imperative that any mission sent to Mars with reduced bioburden requirements remain some conservative distance from any subsurface access points, such as cave openings. Furthermore, though less stringent than current requirements, these missions with relaxed bioburden requirements would still need some level of cleanliness, which could be achieved for instance using standard aerospace cleanliness practices.

The report essentially concluded that missions to Mars’ dry equatorial regions as well as its glacial mid-latitudes pose no risk to contaminating the red planet with Earth life.

While the press release pushes the idea that this is a reduction in the planetary protection rules, it could be seen in a much worse light. Based on the proposed rules, missions to the Martian poles or higher latitudes, where ice is extensive and not “patchy,” might be entirely forbidden. This will significantly limit Martian exploration by the United States. Meanwhile, China and Russia and others will be faced with no such restrictions.

Note too that this report likely forbids SpaceX from landing its Starship in the company’s candidate landing sites, all of which are in the northern lowland plains ranging from 35 to 40 degrees north latitude. This region is thought to have extensive ice sheets very close to the surface. To land there, the rules proposed will either require extremely strict and very costly decontamination procedures, many of which do not even exist as yet, or will forbid landing there at all.

NASA shifts Starliner crew to Dragon to get them in space

NASA announced yesterday that it is is changing the launch assignments of two astronauts from Boeing’s long delayed Starliner capsule to SpaceX’s Dragon capsule, thus allowing them to get into space sooner.

Astronauts Nicole Mann and Josh Cassada were supposed to be among the first human passengers on Starliner during its first crewed flights in the coming years. Now, they’ll fly together on SpaceX’s fifth crewed mission to the International Space Station, which is slated to take place in the fall of 2022.

Both had been assigned to Starliner in 2018, but the delays at Boeing have left them stranded on the ground while others are flying. Worse, it is now unclear when Starliner will launch, as Boeing has not yet resolved the serious valve issue that scrubbed the launch of Starliner’s second unmanned demo mission in August.

Honda developing reusable rocket

Capitalism in space: As part of a larger plan to diversify its product line, Japanese car manufacturer Honda announced on September 30th that it is developing a reusable rocket comparable to Rocket Lab’s Electron.

Honda’s press release can be found here. In it the company also proposes to develop technologies for use by colonies on the lunar surface.

All of these proposals so far appear to be nothing more than PowerPoint presentations, but according to the first link above, the company says it will spend about $9 billion per year for the next five years on all these projects, which also include developing a robot and an electric plane that takes off and lands vertically. (The dollar amount seems much too high, but it is based on a conversion from the announced $5 trillion yen total Honda says it is going to spend in next five years for this research and development.)

According to the announcement, the rocket won’t launch until 2030, which will get it into the game very late. It better be revolutionary or it won’t garner much business by then.

The wavy and beautiful edge of the northern ice cap of Mars

The scarp of the north pole icecap on Mars
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken on August 7, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows the many layered scarp that forms the edge of the northern polar ice cap on Mars, probably more than 2,000 feet high.

Those layers are significant, as they indicate the many climate cycles that scientists think Mars has undergone over the eons as the red planet’s rotational tilt, or obliquity, rocked back and forth from 11 degrees inclination to as much as 60 degrees. At the extremes, the ice cap was either growing or shrinking, while today (at 25 degrees inclination) it appears to be in a steady state.

Why the layers alternate light and dark is not known. The shift from lighter colors at the top half and the dark bottom half marks the separation between the top water ice cap and what scientists label the basal unit. It also marks some major change in Mars’ climate and geology that occurred about 4.5 million years ago.

Military satellite imagery to be obtained from competitive commercial market

Capitalism in space: The National Reconnaissance Office (NRO) is shifting how it gets the government’s military satellite surveillance imagery so that instead of having a long term contract with one company, multiple satellite companies will compete to provide the data.

Under this new imagery procurement, the NRO plans to buy products from multiple vendors and move beyond the current single-supplier arrangement that the National Geospatial Intelligence Agency signed more than a decade ago with DigitalGlobe, which is now Maxar Technologies. The NGA in 2017 turned over responsibilities for commercial imagery procurement to the NRO, while the NGA remains the primary buyer of commercial geospatial data analytics.

The NRO is expected to select at least three U.S. suppliers and structure the program with onramps for new providers. The agency also will require vendors to sign “end user license agreements” so imagery can be shared across government agencies without additional licensing fees.

This change illustrates how other government agencies are following NASA’s lead and shifting from controlling everything to buying the needed product from the open market. While NRO was getting imagery before from a commercial company, Maxar, depending on a single vendor limited competition and innovation while raising costs.

Buying the data from multiple companies means that NRO will get more choice for less cost.

Sunspot update: The boom in sunspots returns!

It is time for my monthly sunspot update, based on the most recent NOAA monthly graph, showing the changes in the Sun’s sunspot activity during September. That graph is below, annotated to show the previous solar cycle predictions and thus provide context.

In September sunspot activity boomed once again, producing the most sunspots in a month since 2016 and ending the slight drop in activity in August to return to the pattern the Sun has exhibited since the end of solar minimum. Consistently the number of sunspots on the visible hemisphere of the Sun since 2020 has exceeded the April 2020 prediction of the NOAA scientist panel, as indicated by the red curve in the graph.

2018 review by Blue Origin suggested changes that were not adopted

Capitalism in space: Shortly after Bob Smith took over as CEO of Blue Origin he hired a consulting firm to review the company’s corporate culture and management policies, then had a top management briefing to review what that analysis had found.

Notes from that meeting by Blue Origin’s management have now become available, and suggest that the company’s management recognized it needed to make some changes in how it operated in order to better compete with SpaceX. Blue Origin had become hidebound, timid, and structured in a manner that made the creation of cost-effective engineering difficult. For example,

Traditionally Blue team has not been focused on producibility and cost when designing,” another executive commented.

In response to the Avascent’s report on SpaceX’s cost focus, Blue Origin officials also acknowledged that they did not have an effective means of estimating costs before beginning a project. “Blue is riddled with poor estimating,” one executive wrote, specifically citing the New Glenn rocket. “The estimates barely cover the spot cost buy of that material based on market price, let alone the entire part material purchase. How did SpaceX keep to their target cost? They probably did a good job estimating. How they accomplished such good estimating is beyond me right now, but they did it somehow for their early years.” [emphasis mine]

As noted at the link, however, there is no evidence the company every made any of the suggested changes:

Whatever Bob Smith hoped to glean from the Avascent study, it’s not clear that the work has had a salutary effect on Blue Origin’s culture.

In the nearly three years since the report’s completion, SpaceX has gone on to launch more than 60 rockets, including four human missions, into orbit. SpaceX also has leaped ahead on a number of other fronts, including winning a multi-billion contract from NASA to build a Human Landing System for the Artemis Moon Program.

Blue Origin, by contrast, has succeeded in launching a single human flight on its New Shepard system—carrying Bezos into space for a few minutes in July. The company’s first orbital flight likely remains about three years away. Far from embracing openness, it remains more opaque than ever. And there are emerging questions about the company’s culture.

I would be more blunt. Prior to Bob Smith’s arrival in 2017 Blue Origin’s management style appeared somewhat similar to SpaceX’s, with regular almost monthly test flights of New Shepard. After he arrived everything slowed down, with the management style becoming all the things the 2018 Avascent study found wrong. And in the three years since that report and management meeting, it appears Smith did nothing to change anything. Blue Origin appears to remain a hidebound company going nowhere.

The company has vast resources due to the cash that Jeff Bezos has poured into it. It needs some good courageous leadership however. The main question will be whether Bezos can provide that.

Due to cracks, Russia will no longer use Zvezda’s docking port

Russian officials today revealed that they will no longer use the docking port on its Zvezda module on ISS because of the stress fracture cracks they have found in the section where that port is located.

Russia is unable to use one of the docking ports of the ISS to its full extent due to cracks in the transitional chamber of the Zvezda module, the general designer of Russia’s Energia corporation, associate member of the Russian Academy of Sciences Vladimir Solovyov said on Monday. “The transitional chamber’s loss of airtightness is often mentioned these days. We are very fortunate the cracks are at the end. We shut down that compartment, thus losing one docking port, which narrows our opportunities somewhat. The crack is very insignificant, though,”

In other words, they have sealed the aft section of Zvezda to reduce further air leaks, thus also closing off access to the port.

The Russian portion of ISS presently has two docking ports on two different modules. When Roscosmos launches its Prichal docking hub in November, to be attached to Nauka’s port, they will then add four more ports.

This decision underlines the impending end to ISS’s life span. Zvezda is not the only old Russian module on ISS where stress fractures have been found. “In August they found cracks in the module Zarya, the oldest module on ISS.

Though the U.S. part of ISS shows no such problem, it is designed to rely on the Russian half for its operations. If Russia must shut down its modules then the station will not be able to function for much longer.

The U.S. will likely overcome some of these issues with the planned launch in ’24 of Axiom’s private commercial module to ISS, which will eventually evolve into an complete space station separate from ISS. For the Russians the pressure to design and launch their own new station has become more critical. Whether they can do it however is unknown. Russia has not built a new space station module in decades. Their new ISS module, Nauka, was built in the 1990s.

Space Force payload problems force delay until ’22 of next Falcon Heavy launch

Capitalism in space: The Space Force has announced that because more time is needed to prepare its military payload, the next Falcon Heavy launch, scheduled later this month, will be delayed until ’22.

This is not the first time payload issues have delayed the launch, which had been previously scheduled for July. The Space Force has not announced a new launch date, nor was it very specific in describing the issues that has forced this delay.

As for the Falcon Heavy, though there has been a long delay since its last flight in June 2019, it appears that SpaceX has four launches scheduled for ’22, with another six already contracted and scheduled for later.

Russia imposes new restrictions on any reporting of Roscosmos

According to this report of today’s launch by Russia of a movie crew to ISS, Putin’s government has just passed new restrictions on reporting of its space effort by Russian citizens, either in or out of Russia.

The new regulations, which took effect on September 29, 2021, essentially prohibit Russians from reporting on the Russian space program outside of Russia. Violators of these regulations will be classified as “foreign agents” — which would create numerous legal issues for Russian citizens.

Specifically, the new regulations target the field of military and technical activities that are not related to or connected in any way with state secrets but which, with vague language, “can be used against Russia.” Most of the activities on the newly released list by the FSB specifically focus on Roscosmos. Prohibited topics of reporting regarding Roscosmos now include information on investigations conducted by the agency, the organization’s financials, condition of rockets and ground support equipment, development plans for Roscosmos vehicles, Roscosmos’ cooperation with other nations for space activities, and new technologies.

These rules essentially forbid Russian citizens from publishing almost anything that Roscosmos itself does not publish. If they do so without permission from outside the country, returning to Russia will become very problematic.

UAE to launch probe to asteroid belt

The new colonial movement: The United Arab Emirates (UAE) today announced that it is planning an unmanned probe to visit a number of asteroids in the asteroid belt.

The project targets a 2028 launch with a landing in 2033, a five-year journey in which the spacecraft will travel some 3.6 billion kilometers (2.2 billion miles). The spacecraft would need to slingshot first around Venus and then the Earth to gather enough speed to reach an asteroid some 560 million kilometers (350 million miles) away.

It appears they have not yet chosen their targets in the belt.

The big question will be how much of this project will be built in the UAE, and how much they will have to farm out to others. For their Al-Amal Mars orbiter, the satellite was mostly built by U.S. universities, as they trained UAE engineers, who now run the mission entire.

Russia launches movie director and actor to ISS

Capitalism in space: Early today Russia successfully used its Soyuz-2 rocket and Soyuz capsule to launch a movie crew to ISS to begin a twelve day visit where they will film scenes for a science fiction movie.

An actress Yulia Peresild and a movie director Klim Shipenko arrived at the International Space Station aboard the Soyuz MS-19 spacecraft on Oct. 5, 2021, for a 12-day visit to shoot scenes of a sci-fi drama. They were accompanied by a professional cosmonaut Anton Shkaplerov, who had to switch to manual control during the final approach to the station due to a failure of the Kurs automated rendezvous system aboard Soyuz. Shkaplerov will remain aboard the station for nearly six months.

This is the second in a steady string of passenger commercial spaceflights that have been purchased by various people from either Roscosmos in Russia or SpaceX in the U.S. We shall see two more such flights in December, and another early in ’22, with additional flights to be scheduled beyond that. The full list, at this time:

  • September 15, 2021: SpaceX’s Dragon capsule flew four private citizens on a three day orbital flight
  • October 2021: The Russians launch two passengers to ISS for 12 days to shoot a movie
  • December 2021: The Russians will fly billionaire Yusaku Maezawa and his assistant to ISS for 12 days
  • cDecember 2021: Space Adventures, using a Dragon capsule, will fly four in orbit for five days
  • January/February 2022: Axiom, using a Dragon capsule, will fly four tourists to ISS
  • 2022-2024: Three more Axiom tourist flights on Dragon to ISS
  • 2024: Axiom begins launching its own modules to ISS, starting construction of its own private space station
  • c2024: SpaceX’s Starship takes Yusaku Maezawa and several others on a journey around the Moon.

Expect this list to grow. There appears to be plenty of demand for such commercial manned spaceflights, and with more flights and more competition (once Boeing’s Starliner enters the game) the cost will certainly drop.

The leaders in the 2021 launch race:

34 China
23 SpaceX
16 Russia
4 Northrop Grumman

With this launch Russia has now exceeded the number of launches it completed last year. If they complete all their presently scheduled launches for ’21, Roscosmos will have its best year since 2015.

The U.S still leads China 35 to 34 in the national rankings.

Worldview to once again develop stratospheric tourist balloon flights

Capitalism in space: The Tucson-based high altitude balloon company Worldview has now announced that it is going to once again develop tourist balloon flights.

World View, based in Tucson, Ariz., announced Oct. 4 it is developing a passenger capsule that will be carried aloft by balloons to altitudes of about 30 kilometers. The Explorer Space Capsule will host eight passengers and two crew for flights lasting 6 to 12 hours, giving people a view of the Earth the company argues resembles that seen from space.

Tickets will cost $50,000 per person, with World View providing what it calls “flexible financing options.” The company expects the first flight no earlier than early 2024, with the nonprofit organization Space for Humanity, which offers spaceflight experiences for those who cannot afford tickets, buying the inaugural flight….

This project is a return to World View’s origins nearly a decade ago. The company originally said it would develop a stratospheric balloon system called Voyager for carrying people, offering them an aspect of the spaceflight experience without actually going to space. However, several years later the company shifted its attention to uncrewed balloons called “stratollites” that carry imaging and communications payloads into the stratosphere for weeks at a time.

The company’s CEO said they are hoping to pick up business from the suborbital market by offering a near-space experience that lasts hours for about one tenth the cost.

Worldview is now in direct competition with Space Perspectives, based in Florida and intending to fly passengers on high altitude balloon flights by ’24, but for $125k per ticket. That company was founded by the same people that founded Worldview.

Land of Martian slope streaks

Land of Martian slope streaks
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 the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a typical example of the many slope streaks found in the rough and very broken region north of the Martian volcano Olympus Mons, the largest in the solar system.

See this May 2019 post for a detailed explanation of slope streaks. While they appear to be avalanches, they do not change the topography of the ground, sometimes flow over rises, and appear to be a phenomenon entirely unique to Mars. While no theory as yet explains them fully, the two most favored postulate that they are either dust avalanches or the percolation of a brine of chloride and/or perchlorate in a thin layer several inches thick close to the surface. In both cases the streak is mostly only a stain on the surface that fades with time.

The location of this cool image however tells us something more about them.

Italy switches from Arianespace to SpaceX for launch contract

Capitalism in space: Because of the two recent launch failures of Arianespace’s Vega rocket (built mostly in Italy), the Italian space agency (ASI) has decided to take the launch of an Earth observation satellite from Arianespace and award the launch contract instead to SpaceX.

The article at the link describes in detail the history and politics that make this decision significant. Essentially, because Arianespace in the past decade has failed to meet the challenge of SpaceX, so that its launches continue to be more expensive, this government-subsidized business has tried to force nations in the European Space Agency (ESA) to use Arianespace rockets via political agreements.

With this decision Italy is defying that pressure, which in turn is going to increase the pressure on Arianespace to finally step up its game, or die from lack of business. For example, when the ESA agreed to have Arianespace build its next generation rocket, the Ariane 6, it failed to require it to be reuseable. The Ariane 6 rocket was therefore designed as an expendable rocket, which meant that right from the start it could not compete with SpaceX’s Falcon 9. It has therefore failed to win launch contracts.

Expect the Ariane 6 to continue to fade as the years pass, simply because the bureaucrats in ESA and Arianespace refused to take their competition seriously.

William Shatner to fly on next New Shepard suborbital flight

Capitalism in space: Blue Origin today announced that William Shatner will join three other passengers on its next New Shepard suborbital flight, presently scheduled for October 12th.

Today, Blue Origin announced actor William Shatner and Audrey Powers, Blue Origin’s Vice President of Mission & Flight Operations, will fly on board New Shepard NS-18. They will join crewmates Chris Boshuizen and Glen de Vries for the flight which lifts off from Launch Site One on October 12.

Powers appears to be flying as both a reward for her work at Blue Origin and as a engineer to observe the operation of the spacecraft.

Shatner, an actor for more than six decades and most famous for his role as James T. Kirk in Star Trek, is 90 years old, which will make him the oldest person to ever fly into space.

BeppiColombo’s first images of Mercury

Mercury by BebiColomo
Click for full image.

This past weekend the European/Japanese duel-orbiter mission made its first flyby of Mercury, taking its first images of that planet.

The photo to the right is one example, cropped and reduced slightly to post here. It was taken by the spacecraft’s monitoring cameras, designed for engineering purposes, which means the resolution is not very high and the camera is positioned so that parts of the spacecraft were visible in each shot. For example, the white strut in the lower right is the spacecraft’s magnetometer boom, which also was used to gather data during the flyby.

Still, the photos demonstrated that the spacecraft is pointing correctly and on course. It will complete five more Mercury fly-bys before going into orbit in 2025.

The next flyby will occur in June ’22.

NASA issues request for commercially-built spacesuits for its Artemis program

Capitalism in space: After more than a decade of delays in building its own in-house next generation spacesuits, NASA this week issued a request for proposals from the commercial space industry for new spacesuits for its Artemis program.

Bidders can use the technology NASA developed for [its unfinished upgraded spacesuits] in its proposals, or they can use their own designs, the document states. The suits must be able to meet a variety of requirements, including up to six spacewalks on the lunar surface during initial Artemis Moon missions. They must also be made of materials such that less than 100 grams of lunar regolith is brought back into the “cabin environment” after each spacewalk on the Moon. NASA plans to award a contract by next April.

The plan is comparable to what NASA has been doing across the board now for the last three years, buy the product from the commercial sector in a fixed price contract. The company that builds the suits will retain ownership of the design, and can make money selling its use to others.

This policy approach continues the agency’s acceptance of almost all the recommendations put forth in my 2017 policy paper, Capitalism in Space, a free pdf download.

It also likely means NASA might finally get the spacesuits it needs for future lunar missions quickly and at a reasonable cost, something the agency itself has been unable to do.

Inactive volcano vent on Mars

Inactive volcanic vent on Mars
Click for full image.

Overview map

Cool image time! The photo to the right, cropped, reduced and annotated to post here, was taken on July 30, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The left image shows a pit that the scientists label a “vent” near the giant volcano Pavonis Mons. The right image is identical, except that I have brightened it considerably to bring out the details in the shadowed area.

As you can see, this pit is filled, and does not appear to have any existing openings into more extensive underground passages.

The white dot on the overview map on the right shows this vent’s location, to the south of Pavonis Mons, and in line with the giant crack that splits three of Mars’ four largest volcanoes. The vent is even aligned the same as that crack, from the northeast to the southwest. The black dots mark the locations of the many cave pits found in this region.

Was this a volcanic vent? If you look at the full image you will see that this pit aligns with a shallower pit to the southwest, with a depression linking the two. Visually this suggests this is a faultline which in turn makes for a good outlet point for lava flow.

Though the data suggests this is a volcanic vent, that supposition is as yet unproven. The full image does not show much evidence of a flow from the pit, which suggests instead that we are merely looking at a spot where the ground cracked along fault lines.

Two nearby asteroids found with more precious metals than Earth’s entire global supply

The precious metals on asteroid 1986 DA, compared to the world's reserves

Capitalism in space: Astronomers have now identified two metal-rich asteroids in orbit near the Earth, with one having a precious metal content that likely exceeds the Earth’s entire reserves.

From the paper’s conclusion:

We estimated that the amounts of Fe, Ni, Co, and the PGM present in 1986 DA could exceed the reserves worldwide. Moreover, if 1986 DA is mined and the metals marketed over 50 yr, the annual value of precious metals for this object would be ∼$233 billion.

The graphic to the right, figure 13 from the paper, illustrates the amount of precious metals available in asteroid 1986 DA, compared to the world’s entire reserves (FE=iron, Ni=nickel, Co=cobalt, Cu=copper, PGM=platinum group metals, Au=gold). From this single metal asteroid a mining operation could literally double the metal that had been previously mined on Earth.

In estimating the value of these metals, the paper tries to account for the certain drop in price caused by the flooding of so much material into the market. It is a guess however. What is clear is that this asteroid could easily serve as a supply house not for Earth but for all future colonies in space. While expensive for Earth use, for colonies already in space the material would be relatively easy to reach and mine. The colonies will already have the transportation infrastructure, since they couldn’t exist without rockets and interplanetary spacecraft. And mining and processing this asteroid material will be far easier and cheaper than trying to find it on Mars and then process it.

Asteroid 1986 DA is estimated to be about 1.7 miles across, based on radar data obtained during a close Earth fly-by in 2019. The second asteroid, 2016 ED85, appears to have a similar content from spectroscopy, but no radar data has as yet been obtained of it, so much less is known.

Biden signs budget continuing resolution, preventing shutdown

At the very last second Congress and President Biden passed and signed another budget continuing resolution that will keep the federal government operating till December and thus preventing another shutdown.

From NASA’s narrow perspective, the action means that the asteroid mission Lucy will likely launch in October as planned. From the perspective of the nation, this last second action merely illustrates the overall failure of the federal government and the elected officials who have been tasked to run it. They are all incompetent, and wouldn’t last five seconds in a real job outside the government.

That the voters keep re-electing them also speaks poorly of America today. We all should be ashamed.

Former Blue Origin employee blasts company for sexism and safety issues

Food fight! While the past two days have been filled with silly back-and-forth barbs between Elon Musk and Jeff Bezos, none of which really matters (which is why I haven’t posted anything about it here), today came the publication of a long scree by a former Blue Origin employee blasting the company for sexism and safety issues.

The rant by Alexandra Abrams, former head of Blue Origin Employee Communications, claims it is co-signed by twenty other present and former Blue Origin employees, but provides no information as who those individuals are. The accusations themselves are all hearsay, since Abrams simply recounts experiences of unnamed others, without any documentation.

Could there be management problems at Blue Origin? Certainly. The real evidence in the past five years suggests that CEO Bob Smith has not done well to get the company off the ground. Not only has Blue Origin accomplished little under his tenure, employees are apparently not happy there, with many fleeing the company.

Abrams’ rant however comes off more like she is a disgruntled former employee who was let go because she was pushing social justice issues rather than focusing on getting her job done. Her use of worn leftist phrases like “climate justice” and “gender gaps” suggests this strongly. The response from Blue Origin to her essay reinforces that impression, noting that she was fired for doing things that could have gotten Blue Origin shut down by the federal government:

Ms. Abrams was dismissed for cause two years ago after repeated warnings for issues involving federal export control regulations.

If so, and Blue Origin would not say this publicly if it wasn’t true, Abrams misconduct could have been very serious indeed. Moreover, as noted at this last link, she was the head of the company’s employee communications department, a division that shouldn’t really be involved in such issues anyway.

This whole kerfuffle reminds me of a similar affair at SpaceX several years ago. A disgruntled former employee made all sorts of similar charges, sued, and lost. I expect a similar result here.

Both companies are in the business of building rockets. Their goal is not “gender equality” or “climate justice”. If that becomes any employee’s first priority, as it appears might have been the case with Abrams, that employee has got to be culled from the company, as that person will only become a cancer that will destroy what everyone else there is trying to accomplish.

FAA extends comment period for SpaceX Starship/Superheavy environmental reassessment

Capitalism in space: The FAA today announced that it has extended the comment period for its environmental reassessment of SpaceX’s operations at Boca Chica, Texas two weeks until November 1st.

From the email announcement:

The Federal Aviation Administration (FAA) has received requests for an extension of the public comment period for the Draft Programmatic Environmental Assessment for the SpaceX Starship/Super Heavy Launch Vehicle Program at the SpaceX Boca Chica Launch Site in Cameron County, Texas (Draft PEA). In consideration of these requests, the FAA is extending the public comment period.

The agency has also changed the dates for the two public hearings it will hold to October 18 and October 20. It will announce more information on those hearings on October 15th.

Orbit of biggest comet ever detected refined

Astronomers have now been able to better refine the orbit and size of Comet Bernardinelli-Bernstein, comet with the largest nucleus ever detected.

A new analysis, led by Bernardinelli and Bernstein themselves, found that the comet nucleus is around 150 km wide, based on its brightness. If so, that makes it the largest comet ever discovered, by quite a margin. Most are only a few kilometers to several dozen kilometers wide, while some particularly big ones, like Hale-Bopp, may be up to 80 km (50 miles) wide. The previous record-holder, Sarabat’s Comet of 1729, has been estimated at about 100 km wide.

The team was also able to calculate the orbit of Comet BB in more detail. This object is on an incredibly long round trip into and out of the solar system – at its most distant point, some 1.5 million years ago, it was about 40,400 AU away. Last time it swung through our neighborhood was about 3.5 million years ago, when it came within 18 AU of the Sun.

But its current inward journey will be its closest so far. Astronomers have already calculated that in 2031, Comet BB will peak at 10.9 AU, almost reaching the orbit of Saturn.

It is presently unclear how bright the comet will be when it reachest its closest point. It will be much farther from the Sun than most bright comets, but its large size may change what is normally expected.

Yutu-2 and Chang’e-4 successfully complete another lunar day on the Moon

According to China’s state-run press, its lunar rover Yutu-2 and the lander Chang’e-4 have now successfully completed another lunar day on the far side of the Moon, with both still functioning well.

Yutu-2 has traveled a total of 839.37 meters, or about 2,753 feet. They are aiming for a location that is still about 3,400 feet away. Based on the rover’s travel pace, about 100 feet per lunar day, it will take them about another two or four years to get there.

FAA clears Virgin Galactic to fly

Capitalism in space: FAA yesterday closed out its investigation into the flight path deviation during the July Virgin Galactic suborbital flight, clearing the company to resume flights.

To prevent future issues, the company will request that a larger zone be restricted on future flights. The FAA also criticized the company for not revealing the flight deviation to the FAA immediately, and demanded the company make sure it doesn’t happen again.

The article at the link also notes that the Virgin Galactic employee whose job it was to provide that information to the FAA resigned the day before this announcement. There is no evidence however that there is any link to the two events, though it is very likely that person was made the fall guy to satisfy the FAA and Virgin Galactic.

Whether flights will resume in mid-October as the company has stated earlier is not clear, as there is no word about whether the manufacturing defect in the flight control equipment revealed by a third-party supplier has been resolved.

Ingenuity’s 14th flight scrubbed by helicopter

Though Ingenuity successfully completed a preflight high speed test of its rotors on September 15th, when it came time to do its fourteenth flight two days later, intended as a short airborne test of that high speed, the helicopter’s computer sensed an issue prior to take-off and scrubbed the flight.

The goal of the high speed test and short flight were to see if Ingenuity could fly during the winter months when the atmosphere of Mars is thinner, thus requiring a higher rotor speed. Initially it was not expected the helicopter would still be operational at this point, so this is another example of it pushing its expected capabilities. The scrub however might be signalling the end date for Ingenuity, related to servo motors that help control the helicpoter:

Ingenuity performs an automated check on the servos before every flight. This self-test drives the six servos through a sequence of steps over their range of motion and verifies that they reach their commanded positions after each step. We affectionately refer to the Ingenuity servo self-test as the “servo wiggle.”

The data from the anomalous pre-flight servo wiggle shows that two of the upper rotor swashplate servos – servos 1 and 2 – began to oscillate with an amplitude of approximately 1 degree about their commanded positions just after the second step of the sequence. Ingenuity’s software detected this oscillation and promptly canceled the self-test and flight.

Our team is still looking into the anomaly. To gather more data, we had Ingenuity execute additional servo wiggle tests during the past week, with one wiggle test on Sept. 21, 2021 (Sol 209) and one on Sept. 23, 2021 (Sol 211). Both of the wiggle tests ran successfully, so the issue isn’t entirely repeatable.

One theory for what’s happening is that moving parts in the servo gearboxes and swashplate linkages are beginning to show some wear now that Ingenuity has flown well over twice as many flights as originally planned (13 completed versus five planned). Wear in these moving parts would cause increased clearances and increased looseness, and could explain servo oscillation. Another theory is that the high-speed spin test left the upper rotor at a position that loads servos 1 and 2 in a unique, oscillation-inducing way that we haven’t encountered before.

Because communications with Mars are now paused for two weeks because the Sun is in the way, the engineering team is holding off further tests until communications resume.

A Mars mesa carved by floods and lava?

Overview map of Kasei Valles

With today’s cool image we once again start our journey from afar, and zoom in. The overview map to the right focuses in on the thousand-mile-long Kasei Valley on Mars.

The blue area is where scientists postulate a lake once existed, held there by an ice dam (indicated by the white line). At some point that ice dam burst, releasing the water in a catastrophic flood that created the braided flow features that continue down Kasei Valles to the northern lowland plain of Chryse Planitia.

The black area marks a giant lava flow that scientists believe came later, following the already carved stream channels for a distance of 1,000 miles, traveling at speeds of 10 to 45 miles per hour.

Flooding from crater lakes on Mars

Loire Valley on Mars

According to a new paper published today, scientists estimate that flooding from crater lakes on Mars — caused by sudden breaches in the crater rims — could have created as much as 25% of the volume of the valley networks that have been identified there.

Mars’ surface hosted large lakes about 3.5 billion years ago. Some of these lakes overtopped their rims, resulting in massive floods that rapidly formed deep canyons. Similar lake breach floods occurred in the northwest United States and central Asia at the end of the last glacial period over 15,000 years ago.

“We found that at least a quarter of the total eroded volume of Martian valley networks were carved by lake breach floods. This high number is particularly striking considering that valleys formed by lake breach floods make up just 3% of Mars’ total valley length,” Morgan said. “This discrepancy is accounted for by the fact that outlet canyons are significantly deeper than other valleys. These floods would have shaped the overall Martian topography, affecting the flow paths of other valleys. Our results don’t negate the importance of precipitation-fed runoff on early Mars. On the contrary, liquid water had to be stable for long enough for lakes to fill from inlet rivers.” [emphasis mine]

The map above shows in white the Loire Valles on Mars, located at about 20 degrees south latitude in transition zone between the northern lowland plains and southern cratered highlands. The paper cites this valley as a typical example of a flood valley caused by a crater rim breach.

This research only makes the geological and climate history of Mars more puzzling. Though the geological evidence strongly suggests lakes and liquid water once existed on Mars, and this research strengthens that conclusion (as indicated by the highlighted sentence above), no model of the planet’s climate has ever satisfactorily created a situation where that was possible. Either there are factors about Mars’ ancient history we have not yet identified (likely) and don’t yet understand (very likely), or the planet’s geology was formed by processes alien to Earth and thus not yet recognized by us.

Government shutdown threatens Lucy asteroid mission

Government marches on! The possibility that the federal government could shut down because of the inability of Congress and the Biden administration to pass a funding bill or raise the debt limit now threatens the launch of the Lucy mission to the asteroid belt.

If no budget agreement is reached the government will shut down on October 1st. If the debt limit isn’t raised that shutdown could follow soon thereafter, even if a budget is passed.

The launch window for the mission is from October 16 to November 7, 2021. If the spacecraft does not launch in that window the science team says it will likely require a major rethinking of the entire project, as it will be difficult to find another opportunity to visit the same set of asteroids.

Right now the chances of a shutdown are very high, as the Democrats are pushing big spending bills without any negotiations with the Republicans. In answer, the Republican caucus has said that none of its members will support raising the debt limit. Without the latter any passed spending bill will soon be moot, as the debt limit will soon be reached, blocking further government spending.

Though I personally would be very saddened if Lucy was prevented from launching, that loss would be well compensated for by having the federal government out of business. The evil and corruption promoted by it far outweighs the good work done by several minor space missions.
