Former Blue Origin employee blasts company for sexism and safety issues

12:04 pm

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

11:11 am

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

10:59 am

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

10:52 am

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

10:35 am

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

10:22 am

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?

1:29 pm

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.

The red dot near the Kasei Valles resurgence is today’s cool image.

Today’s blacklisted American: Suspended for refusing to exempt black students from finals, UCLA professor sues

11:49 am

King's dream banned at UCLA
King’s dream of equal treatment for all
called racist at UCLA

They’re coming for you next: Gordon Klein, an accounting professor at UCLA for 39 years, has sued that university’s Anderson School of Management and its administrators for suspending him for three weeks in June because he refused to favor black students in grading or exempt them from final exams.

Prof. Klein’s alleged offense was that he insisted on treating black students equally. He refused a request by a white student to allow black students preferential treatment on final exams. Because such a racial preference would violate UCLA’s anti-discrimination policies (and maybe even the law), Klein refused. Students then launched a defamatory campaign against Prof. Klein, and the cowards who run UCLA’s Anderson School capitulated, denouncing and suspending Klein. He eventually was reinstated — because he did absolutely nothing wrong — but not before his reputation and career were severely damaged.

..Prof. Klein has just filed a lawsuit in California state court, and among the things he wants, is for UCLA administrators to be held personally liable. [emphasis mine]

During his suspension Klein was also threatened with violence, requiring an increased police presence at his home to protect him.

Flooding from crater lakes on Mars

9:36 am

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

9:00 am

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.
