Astra schedules next launch attempt

8:36 am

Capitalism in space: The new smallsat rocket company Astra has completed its investigation of its launch failure on August 28th and scheduled its next launch attempt for no earlier than October 27th.

During liftoff, kerosene fuel and liquid oxygen both leaked from the propellant supply system adjacent to the rocket. This system is designed to quickly disconnect and seal when the rocket launches. When LV0006 lifted off, these leaked propellants mixed and became trapped beneath the interface between the rocket and the ground equipment.

These mixed propellants were subsequently ignited by the exhaust of the first stage engines, which caused an over-pressurization that severed the electrical connection which controls the fuel pump. This caused the shutdown of one Delphin on the first stage less than one second after liftoff.

The company has revised its system to prevent further leaks, and shifted the fuel lines so that even if there is a leak, the propellants can no longer mix.

Michael Knowles – Celebrating Columbus

6:01 pm

An evening pause: On this day when all should be celebrating Christopher Columbus and his willingness “sail beyond the sunset,” to use a phrase from Tennyson, this short video give us an accurate picture of the man, his times, and his achievements. It also puts the lie to the bigoted, hateful, leftist slanders that have been used in recent years to poison his legacy.

Note that I got this video from Rumble. I ask all who wish to suggest evening pauses to consider searching on Rumble and Vimeo, so that we are less dependent on YouTube. The Google company needs to feel some competitive pressure.

Ancient fossil river in the very dry equatorial regions of Mars

1:27 pm

Inverted Channel on Mars
Click for full image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken on August 29, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label an “inverted channel in Arabia Terra,” a small example of the more than 10,000 miles of fossilized rivers in this region on Mars that scientists have identified using MRO.

They are made of sand and gravel deposited by a river and when the river becomes dry, the channels are left upstanding as the surrounding material erodes. On Earth, inverted channels often occur in dry, desert environments like Oman, Egypt, or Utah, where erosion rates are low – in most other environments, the channels are worn away before they can become inverted. “The networks of inverted channels in Arabia Terra are about 30m high and up to 1–2km wide, so we think they are probably the remains of giant rivers that flowed billions of years ago. [emphasis mine]

Since this fossilized river is located at 11 degrees north latitude, smack in the middle of the dry equatorial regions of Mars, it has certainly been a dry desert for a very long time. You can see how barren the terrain appears by looking at the wider view afforded by MRO’s context camera below.

Today^s blacklisted American: Volunteers at the Art Institute of Chicago fired for being mostly white

11:54 am

Discriminated against in Chicago
Discriminated against by the Art Institute of Chicago.

“Segregation today, segregation tomorrow, segregation forever!” The Art Institute of Chicago (AIC) has fired all 122 of its unpaid volunteer docents because they happen to be mostly white.

Many of the volunteers—though not all—are older white women, who have the time and resources to devote so much free labor to the Museum [average length of service 15 years]. But the demographics of that group weren’t appealing to the AIC, and so, in late September, the AIC fired all of them, saying they’d be replaced by smaller number of hired volunteers workers who will be paid $25 an hour. That group will surely meet the envisioned diversity goals. [emphasis mine]

Let me translate the highlighted words more honestly and accurately:

Washington Post slams Blue Origin

9:18 am

Capitalism in space: In a long article today the Washington Post — owned by Jeff Bezos — harshly criticized the management at Bezos’s space company Blue Origin, confirming earlier stories last week (here and here) and published by other news sources that accused the company of poor management and an unhealthy corporate culture. From the Post’s article:

The new management’s “authoritarian bro culture,” as one former employee put it, affected how decisions were made and permeated the institution, translating into condescending, sometimes humiliating, comments and harassment toward some women and a stagnant top-down hierarchy that frustrated many employees.

Though the story strongly confirms those earlier reports, I found it somewhat hilarious in that it seemed far more interested in “woke” issues than Blue Origin’s inability to get anything actually built.

However, that Jeff Bezos allowed the Washington Post to publish it suggests strongly that Bezos is getting ready to take harsh action at Blue Origin, and is laying the groundwork through his newspaper. If so, this is excellent news, as it might mean this very disappointing company might finally get back on track.

Weather delays New Shepard’s Shatner launch one day

8:56 am

Capitalism in space: Because of high winds predicted for tomorrow, Blue Origin has delayed its next suborbital flight of New Shepard, carrying four private citizens including William Shatner, for one day to October 13th.

The launch is scheduled for 9:30 am (Eastern), with live coverage beginning at 8 am (Eastern) on Blue Origin’s website. Be warned, however. If you watch with the sound on you will likely have to listen to a lot of hype and blather from the company’s announcers, who routinely can’t keep their mouths shut and have to tell us over and over and over again how “spectacular” and “breath-taking” and “historic” this all is.

If they do pause in their hyperbole, however, listening to Shatner during the flight will likely be worth it. The man has wit and knows how to use it.

OneWeb to use India’s rockets for satellite launches

8:44 am

Capitalism in space: OneWeb today announced that it has signed a deal with India to use its rockets for satellite launches.

Low Earth orbit (LEO) satellite communications company OneWeb has announced its plans to collaborate with the commercial arm of the Indian Space Research Organisation (ISRO), NewSpace India Limited (NSIL), to utilise indigenously built Polar Satellite Launch Vehicle (PSLV) and the heavier Geosynchronous Satellite Launch Vehicle (GSLV-MkIII) as likely platforms to launch OneWeb’s satellites in India from next year.

This is not good news for either Russia or Arianespace. Up to now these entities pretty much were launching all of OneWeb’s satellites. Now some of that business is being shifted to India.

The deal was revealed at a press conference that announced the formation of an Indian commercial trade organization, the Indian Space Association (ISpA), that partnering with the government will use the government’s space assets to develop private commercial space resources.

The Indian Space Association (ISpA) will be headed by Jayant Patil, senior executive vice president – Defence, L&T-NxT as its chairman, and Bharti Airtel’s chief regulatory officer Rahul Vatts as its vice-chairman, while Lt Gen. A.K. Bhatt (Retd.) has been appointed as the director-general of the association.

Among its early members include Bharti Airtel, Larsen & Toubro, Nelco (Tata Group), OneWeb, Mapmyindia, Walchandnagar Industries and Ananth Technology Limited.

Bharti is the company that invested $500 million to bring OneWeb out of bankruptcy, partnering with the United Kingdom.

The key question is whether these private companies will invest in developing private rockets, or will simply continue to launch using ISRO’s rockets. Based on this announcement, it appears the latter, but since the whole goal here of the Modi government of India appears to be to encourage a private sector, this could soon change.

Putin reduces budget for Roscosmos by 16%

9:06 am

The Putin government has significantly cut the budget for Roscosmos, reducing it by 16% for each of the next three years.

For 2022, the state budget for space activities will be set at 210 billion rubles ($2.9 billion), a cut of 40.3 billion rubles ($557 million) from the previous year. Similar cuts will follow in subsequent years. The most significant decreases will be in areas such as “manufacturing-technological activities” and “cosmodrome development.” Funding for “scientific research and development” was zeroed out entirely.

The publications say Russian President Vladimir Putin is unhappy with the performance of Russia’s space program. At a space industry meeting on September 29, they report, Putin criticized the industry’s failure to fulfill directives on long-term goals in the space sphere. In 2020, for example, Roscosmos failed to hit 30 of the 83 stated goals of the national space program.

Putin’s dissatisfaction is quite justified. Since his government consolidated all of Russia’s aerospace industry into a single corporation run by Roscosmos, the space agency has made many promises but achieved little. It is clear that he hopes these cuts will force it to get its act together.

The problem is that Putin has done nothing to change the root cause that has fueled this failure, the government aerospace monopoly that Putin himself created. Without competition and a willingness to allow new Russian aerospace companies to succeed — in direct competition with Roscosmos — there is little chance of reform. Roscosmos will struggle on, and it might even begin to show a bit of success, but in the end its best prospect is to become one of many competitors in the new commercial space market. And its market share will be small, because the competitive private companies in the west will easily beat it in cost and innovation.

As expected, Pluto’s atmosphere is freezing as its orbit takes it from the Sun

10:48 am

Data from ground-based telescopes has now confirmed that Pluto’s nitrogen atmosphere has begun it annual winter freeze out as the planet’s somewhat elliptical 248-year-long orbit takes it away from the Sun.

For about 25 years, Pluto has been moving farther and farther away from the sun, so its surface temperature has been going down. And with these recent observations, the researchers found evidence showing that Pluto’s atmosphere is actually refreezing back onto its surface as the dwarf planet gets colder and colder. Pluto is so far from the sun that, as time goes on, it will get distinctly farther away (and colder) before getting closer to the sun in other regions of its immense orbit.

The astronomers were able to detect this refreezing by observing the planet as it eclipsed a star in 2018.

SpaceX now valued at $100 billion, the world’s 2nd most valuable private company

10:40 am

Capitalism in space: Because of the high price that some of its investors were able to get selling their private shares of SpaceX, the company’s valuation was reassessed upward from $74 to $100 billion and making it the second most valuable private company in the world.

The stock sale did not raise money for SpaceX as it was a secondary sale by these investors to get a profitable return on their initial investment. Regardless, the stock price they were able to get increased the company’s value.

The high price also illustrates objectively what investors think of SpaceX’s value. No matter what the critics may say, when the time comes to lay the money on the table, those willing to do it are convinced SpaceX is going to be successful in cashing in on its various space projects.

New Horizons discovers two binary asteroids in Kuiper Belt

10:32 am

Overview map
Click for full map.

As New Horizons traveled from Pluto to the asteroid Arrokoth in 2018, scientists used it to take images of the relatively nearby asteroids that it was passing, and found that two of those asteroids appeared elongated.

[T]he team fit the shapes with a two-body model: two asteroids in a tight orbit. Even though the individual rocks weren’t resolved, the modeling showed that two bodies were better able to explain the elongation, as well as the brightness seen. The model for 2011 JY31 had two 50-km-wide objects nearly 200 km apart, while for 2014 OS393, the model had slightly smaller bodies (30 km across) that orbited each other 150 km apart.

The map, cropped and further annotated by me, shows New Horizons’ path during this time period, with the two binary asteroids indicated in blue.

This data, combined with the double lobe shape of Arrokoth (formerly named Ultima Thule), strongly suggests that it was not unusual for these primitives asteroids in the early solar system to coalesce from comparably sized partners.

Update on Boeing’s investigation into Starliner valve issue

10:10 am

NASA yesterday issued an update on Boeing’s investigation into Starliner valve issue, noting that progress is being made.

Boeing has demonstrated success in valve functionality using localized heating and electrical charging techniques. Troubleshooting on the pad, at the launch complex, and inside the Starliner production factory at Kennedy Space Center has resulted in movement of all but one of the original stuck valves. That valve has not been moved intentionally to preserve forensics for direct root cause analysis.

Most items on the fault tree have been dispositioned by the team including causes related to avionics, flight software and wiring. Boeing has identified a most probable cause related to oxidizer and moisture interactions, and although some verification work remains underway, our confidence is high enough that we are commencing corrective and preventive actions. Additional spacecraft and component testing will be conducted in the coming weeks to further explore contributing factors and necessary system remediation before flight.

…Boeing has identified several paths forward depending on the outcome of the testing to ultimately resolve the issue and prevent it from happening on future flights. These options could range from minor refurbishment of the current service module components to using another service module already in production. [emphasis mine]

The announcement also confirmed that the next launch attempt of the unmanned demo mission is now being targeted for “the first half of 2022, pending hardware readiness, the rocket manifest, and space station availability.”

The highlighted words raise a very serious question. How is it possible for “oxidizer and moisture interactions” to cause this problem now on Starliner, when the environmental conditions at Cape Canaveral for spacecraft have been understood for better than sixty years? Though this problem might have uncovered a previously undetected fundamental engineering issue related to valves, I am very skeptical. It seems more likely that some quality control issue occurred during this capsule’s assembly. That they are considering using a different Starliner capsule for the demo flight strongly confirms this, suggesting again that the valve issue is not systemic to all valves but is specifically linked to the assembly of this capsule.

If this speculation is correct, it suggests there are some some very disturbing quality control problems in Boeing’s Starliner design and assembly processes. First they missed about sixty software issues that forced the premature landing of the capsule in the first demo flight, issues that should have been fixed during design and construction. Now it appears they have discovered assembly problems with the capsule’s valves, and only did so mere hours before launch.

Boeing has got to get these issues fixed, or it is going to have a serious public relations problem garnering private customers outside NASA once Starliner begins commercial flights.
