GAO: Problems with Blue Origin’s BE-4 engine threaten ULA’s Vulcan rocket

Capitalism in space: According to a new report [pdf] issued by the Government Accountability Office (GAO) on June 8th, on-going technical issues with Blue Origin’s BE-4 rocket engine threaten ULA’s planned inaugural launch of its new Vulcan rocket later this year.

From page 106 of the report:

A U.S. produced rocket engine [BE-4] under development [by Blue Origin] for ULA’s Vulcan launch vehicle is experiencing technical challenges related to the igniter and booster capabilities required and may not be qualified in time to support first launches beginning in 2021. A joint program office and ULA team is tracking these challenges, and NSSL officials told us Vulcan remains on track to support first launches and certification in 2021. However, if ULA cannot complete engine qualification before the 2021 flight certification, the program might continue to rely on ULA’s Atlas V—which uses engines manufactured in the Russian Federation—to support ULA’s 2022 launches, despite a nearly $2.9 billion investment in new launch system development. [emphasis mine]

ULA has a limited number of Russian engines in its inventory. At some point it must move on to American-built engines, and if Blue Origin’s BE-4 cannot be fixed then the company will be forced to look for other options.

Both ULA and Blue Origin maintain that the first Vulcan launch will occur in the fourth quarter of this year, launching Astrobotic’s lunar lander Peregrine to the Moon, but no date has been announced. If this GAO report is describing problems that still remain as of June 2021 and have not been fixed, then expect a further delay to be announced, probably by September.

These technical issues with the BE-4 engine also impact Blue Origin’s plans to begin launching its orbital rocket, New Glenn, next year. That rocket is already two years behind schedule, delays caused partly by these engine issues and partly due to the requirements imposed by the military under the above-mentioned $2.9 billion program to develop new launch systems. Without that new engine, Blue Origin’s much-touted effort to compete with SpaceX for commercial launches will go up in smoke.

Astronauts complete installation of 1st set of new solar panels on ISS

Astronauts yesterday successfully completed the installation of the first set of new solar panels on ISS, completing the work they could not do on a first spacewalk because of issues with one of the astronaut’s spacesuits.

The new panels are deployed on top of the old panels. Though smaller, they are more efficient, so they actually produce more energy total.

The IROSAs [acronym for the new panels] will be installed on top of six of the station’s existing solar arrays, which will allow the IROSAs to utilize the same sun-tracking motors and be connected into the same electrical system as the current arrays.

With the IROSAs being around 30% efficient, compared to the 14% efficiency of the original arrays, the IROSAs will generate roughly the same amount of power as the originals despite being only half their size. Each IROSA will produce 20kW of additional power, for a total of 120kW across all six arrays.

However, because the IROSAs are smaller, they will not completely cover the half of the six [old panels] they’ll be installed over. Instead, portions of the original arrays will still be power positive. The unshadowed portions of the original arrays will continue to produce 95kW as a result, making for a combined total of 215kW of power available to the ISS — an increase of nearly a third compared with the outpost’s current levels.

The set installed yesterday was the first of six new panels to be installed, replacing all of the old panels.

First attempts to fix Hubble fail

An attempt to switch the Hubble Space Telescope to a different backup computer module in order to bypass a broken unit failed last week, leaving the telescope in safe mode.

A payload computer on Hubble stopped working June 13, the agency said in a June 16 statement. Engineers speculated that the computer, used to manage operations of Hubble’s science instruments, malfunctioned because of a degrading memory module, putting the instruments into a safe mode.

The agency said at the time that it would switch of a backup memory module that day and, after about a day of testing, restart the instruments and resume science observations.

However, in a June 18 statement, NASA said those efforts to switch to a backup memory module failed because “the command to initiate the backup module failed to complete.” An attempt to restore the computer with both the original memory module and the backup unit also failed.

While the engineers at the Space Telescope Science Institute, that operates Hubble, have expressed confidence they can overcome these issues, the failures this week are truly troublesome. We may truly be facing the end of the telescope,

A confused river of ice on Mars

A river of ice on Mars
Click for full image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken on March 4, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what MRO’s science team labeled a “Landform in Source Region of Harmakhis Vallis.”

They are being very correct and careful with that label. The landform here is quite clearly reminiscent of a glacier, but because they don’t yet have confirmation of its watery nature, as good scientists they can’t call it that.

I however am a mere journalist, so I am free to speculate more wildly. Sure looks like glaciers to me, the ice flowing downhill from the left to the right and flowing around that central mound.

The overview map below gives a wider context, but also makes the behavior of the glaciers here far more puzzling.

Today’s blacklisted American: George Mason University to blackball whites and men in hiring

The Civil Rights Act of 1964: repealed by George Mason University.
The Civil Rights Act of 1964:
Doesn’t exist at George Mason University.

The new bigotry on American campuses: In an email sent out to his entire faculty in mid-May, George Mason University president Gregory Washington demanded that the university’s hiring practices specifically discriminate in favor of minorities and women over whites and men.

Washington further argued that the faculty at GMU do not proportionally represent the ethnicities of the student body or the surrounding region. A vision of diversity and inclusion in hiring “is a recognition of the reality that our society’s future lies in multicultural inclusion,” he said in his email.

This begins by redefining “best” to include “lived experiences” as a top hiring criteria alongside professional aptitude, he stated. In short, “We either believe that diversity and inclusion can improve our performance, or we don’t,” Washington stated.

Consequently, Washington recommended hiring based jointly on teaching ability, research achievements, and openness to diversity. The result, he argued, will support minorities who don’t have equal access to opportunities for success.

To really get a flavor of Washington’s discriminatory recommendations you need to read his whole email. » Read more

Japanese scientists complete inventory of Ryugu asteroid samples

In a press conference yesterday the Japanese space agency JAXA announced that scientists have completed their inventory of the samples brought back from the asteroid Ryugu by the Hayabusa-2 spacecraft, and are now ready to begin distributing those samples to scientists around the world for more detailed research.

JAXA has cataloged the soil samples brought back by Hayabusa 2 last December, by size, color and shape. From now, 269 researchers from 14 countries, including Japan and the United States, will conduct an in-depth analysis of the soil’s structures and components over the course of about a year.

As expected, the inventory found the samples had a large amount of hydrogen, oxygen, and carbon atoms. Even before Hayabusa-2’s arrival, Ryugu had been catalogued as a “hydrated” asteroid, which means it was thought to contain a lot of hydrogen and oxygen, the basic elements of water. The inventory has now confirmed this.

Japan passes law protecting property rights in space

Japan’s legislature on June 15th approved a new law designed to protect the ownership of the resources private entities extract for profit in space.

Japan’s legislation is similar to provisions in the Commercial Space Launch Competitiveness Act, passed by the U.S. Congress and signed into law by President Obama in 2015. That law grants U.S. companies rights to resources that they extract, but not property rights to celestial bodies, which would run afoul of the Outer Space Treaty. Luxembourg and the United Arab Emirates have since passed similar legislation.

All four countries are signatories of the Artemis Accords, which endorses the ability to extract and use space resources. “The Signatories affirm that the extraction of space resources does not inherently constitute national appropriation under Article II of the Outer Space Treaty, and that contracts and other legal instruments relating to space resources should be consistent with that Treaty,” the accords state.

Both Russia and China oppose such legislation, as well as the Artemis Accords, which have now been signed by eleven countries.

What this growing alignment of opposing sides means for future space operations by private companies is unclear, though it suggests these two countries will not honor those private property rights, which in turn suggests this legal disagreement is eventually going to lead to physical conflict in space.

China’s Long March 2C rocket launches three military satellites

China today used its Long March 2C rocket to launch three military reconnaissance satellites into orbit.

The rocket’s first stage uses highly toxic hypergolic fuels, and is expendable. Since it is launched from the interior of China, that stage always crashes on land, sometimes near residential areas. No word on where it crashed today.

The leaders in the 2021 launch race:

19 SpaceX
18 China
8 Russia
3 Northrop Grumman

The U.S. still leads China 27 to 18 in the national rankings.

U2 – Mysterious Ways

An evening pause: Stay with it for what is made to appear as an impromptu addition of an audience member dancing. She steals the show.

It might be improvised, but if it was, it happened repeatedly, at different places, sometimes with a girl that looks identical to this one. I suspect they pre-planned it each time, but no matter, it works quite well this time, for sure.

Hat tip Cotour.

Today’s blacklisted American: NY accounting program for high school students bans whites

The Civil Rights Act of 1964: repealed by the universities in New York.
The Civil Rights Act of 1964: unilaterally repealed by
the universities in New York.

Blacklists are back and New York’s got ’em! Until Campus Reform revealed its bigoted discriminatory policy, a New York accounting program for high school students specifically excluded whites from applying.

The first link above includes a screen capture of the program’s original application requirements, which included five categories, (1) Hispanic or Latino, (2) Black or African American, (3) Native Hawaiian or Pacific Islander, (3) Asian, (4) Native American or Alaska Native, (5) Two or More Races.

Notice what’s missing? If you are simply white and thus do not fall into these categories, you must go to the back of the bus. For example, my kids (had I any) would be Jewish, white, and of European descent, and thus under these definitions would be forbidden to even apply to the program. And the only reason they would be rejected would be because of their race and ethnicity, a criteria that is a blatant violation of so many anti-discrimination laws passed since the 1960s it boggles the mind.
