Blue Origin’s BE-4 rocket engine experiences more delays

9:27 am

Capitalism in space: Though Blue Origin appears only a few weeks from delivering its first flightworthy BE-4 rocket engine to ULA for use in that company’s new not-yet-launched Vulcan rocket, the second flightworthy engine is further delayed due to technical problems discovered when static fire testing began.

Sources told Ars that the first engine was put onto the test stand in Texas early in August, but almost as soon as work began to hot-fire the powerful engine, an issue was discovered with the engine build. This necessitated a shipment back to Blue Origin’s factory in mid-August, as the company’s test stands in Texas do not allow for more than minor work.

As a result of this technical issue, ULA now appears likely to get one flight engine this month, but it probably will not receive the other one for installation onto the Vulcan rocket before mid-October, assuming a clean battery of tests in Texas.

This issue almost certainly means that Vulcan will not attempt its first launch this year. The rocket is thus more than three years behind schedule.

The problems outlined here however are far greater than simply the technical issues with this one engine. First, Blue Origin’s pace of operations continues to be far too leisurely. Nothing the company has done since 2017 has proceeded with any sense of urgency, and thus neither ULA nor Blue Origin have been able to launch their rockets.

Second, and far more important, Blue Origin is supposed to be manufacturing the BE-4 for two rockets, both Vulcan and its own New Glenn. Neither rocket will be reusable to begin with, which means the number of needed engines required at first will be high. For example, ULA has contracts to launch Vulcan twice almost immediately, with the need to follow these with several military launches. Each launch will require two BE-4 engines, so Blue Origin at a minimum needs to manufacture four engines, probably more, just to fulfill its obligations to ULA. To supply its own New Glenn rocket, it needs seven BE-4 engines for each launch, with the company having four launches on its manifest for 2023.

All told, Blue Origin thus has to deliver, at a minimum, 32 engines in 2023 alone, to meet its contractual obligations. And since the rockets and engines will be untested, expect at least one or two launch failures that will further increase the need for more engines.

Yet, there is no sign that Blue Origin has figured out how to manufacture these engines on an assembly line basis. Even if it gets these two engines delivered soon, it is unclear it can produce a lot of flightworthy engines fast enough to meet this launch schedule. Expect therefore that both rockets will continue to experience launch delays that could stretch out years.

Meanwhile, a plethora of new rocket companies have been appearing, all aiming eventually to compete with Blue Origin and ULA. If Blue Origin doesn’t get a move on, these new companies will soon be in a position to replace both it and ULA, entirely.

Astrobotic acquires bankrupt Masten

9:05 am

Capitalism in space: Astrobotic announced this week that it has successfully purchased Masten, a bankrupt company that for almost two decades specialized in developing suborbital vertical rocket landing technology.

This acquisition will combine the workforce of the two companies, and give Astrobotic control over Masten’s test sites at Mojave. Since Astrobotic is one of the many companies with a NASA contract to build lunar landers, the experience of Masten’s workers — experienced experts in vertical rocket landings — will be immeasurable.

Update on CAPSTONE, still in safe mode

8:57 am

According to a detailed update from Advanced Space, the private company operating CAPSTONE for NASA, engineers have partly recovered control of the spacecraft after an anomaly had caused it to tumble and lose power.

It appears the problem that occurred on September 8th near the end of an mid-course correction engine burn was more serious that NASA initially revealed. CAPSTONE was tumbling out-of-control, its use of power was exceeding the power the solar panels were generating (draining its batteries), and the computer was periodically rebooting.

Since then engineers at Advanced have managed to stabilize the tumbling so that the spacecraft’s batteries were gaining power rather than losing it. Communications were re-established and the computer was also stabilized so that the spacecraft was able to get into a good safe mode. It remains however in a poor orientation that limits communications, power, and prevents proper operations.

While work is ongoing to diagnose the cause of the anomaly, the team is preparing the spacecraft to attempt a detumble operation to regain attitude control of the vehicle. This detumble operation was successfully demonstrated after separation from the launch vehicle in July. A successful detumble will result in the vehicle resuming control of its orientation, orienting the solar panels to the Sun to fully charge the batteries of the power used during the detumble. The spacecraft will then orient to the ground and await further instructions.

When this operation will occur was not stated, but it certainly will take place as soon as possible.

InSight’s power levels rise again

10:16 pm

InSight's power levels through September 10th

Based on another status update issued today by the InSight science team, the electricity generated by the Mars lander’s dust-covered solar panels increased again slightly in the past week, going from 410 watt-hours per day to 420 watt-hours per day.

The graph to the right shows the trends since May. The science team had expected the power levels to steadily drop throughout the summer so that by early September the lander would die.

Instead, the power levels remained steady throughout the summer, and have in the past two weeks actually risen slightly, thus extending InSight’s life.

If at any moment a strong gust of wind or dust devil sweeps over InSight, the panels could be blown clear and it would gain a rebirth. The longer it manages to survive, the greater the chance that this might happen.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

Today’s blacklisted American: Two students harassed and blackballed from a “sexual assault survivor’s club” because they were Jewish

12:33 pm

SUNY-New Paltz: supports blacklisting and anti-Semitism

Two female students attending the State University of New York (SUNY) at New Paltz, Cassandra Blotner and Ofek Preis, have now filed a federal civil rights complaint because of the vicious and hostile treatment that they were subjected to by “the sexual assault survivor’s club” at the college, simply because both were Jewish and supporters of Israel.

You can read their civil rights complaint here [pdf].

Denise Katz-Prober, a Brandeis Center lawyer who represents Blotner and Preis, said in an interview with The College Fix that the two women were treated horribly. “They essentially have been victimized three times,” she said. “They were victimized first when they were sexually assaulted, then by the community of students and support services they turned to, and then by the university when they reached out for help and the university failed to take steps to protect them.”

When the other members of the club, officially called New Paltz Accountability (NPA), learned that both women were ardent and public supporters of Israel, these club members began a campaign to harass and dox the women continuously.

SpaceX appeals FCC decision that cancelled Starlink subsidy

9:35 am

SpaceX’s Starlink division has now appealed the decision by the Federal Communications Commission (FCC) to cancel a nearly $900 million subsidy award given to companies providing broadband to rural regions.

Starlink’s appeal is complex, its arguments appearing to all center on what the company thinks was unfair practices by the FCC in cancelling the award.

Starlink told the FCC it was held to “standards that no bidder could meet today.”

“Changing the rules to undo a prior policy is grossly unfair after SpaceX has invested thousands of employee-hours and millions of dollars preparing to meet its [FCC program] obligations on the reasonable assumption that the Bureau would apply the Commission’s rules in an even-handed manner,” the company said.

That one FCC commissioner has publicly questioned the legality of the cancellation gives some weight to Starlink’ complaint.

In the end, this entire FCC program is a rip-off of the taxpayer. No companies, including SpaceX, should get this money. SpaceX is proving that it can get its constellation launched and operating profitably in rural areas, without a dime of federal money. Why should the rest of us help them do it?

Furthermore, the questionable nature of the FCC cancellation suggests the money from this program is possibly being awarded for political reasons, payoffs to companies that give the most campaign contributions to the right politicians. SpaceX doesn’t give much to any politicians, so it could be the cancellation was done as punishment for that lack.

China’s Long March 7A launches communications satellite; dumps debris on Philippines

9:19 am

China today launched its Long March 7A rocket from its coastal Wenchang spaceport, successfully placing a communications satellite into orbit.

The coastal launch site meant that the rocket’s lower stages would not fall on China’s interior. Instead, it appears the drop zones were located in the Philippines.

The [Philippines Space] agency said it was able to verify the estimated drop zones of the rocket debris from a notice by the Civil Aviation Administration of China. “Two drop zones within the Philippine territory have been identified based on the NOTAM: Drop zone 1 is approximately 71 kilometers from Burgos, Ilocos Norte, while drop zone 2 is approximately 52 kilometers away from Sta. Ana, Cagayan,” PhilSA said in an advisory.

No word on whether this debris caused any damage. Regardless, China is continuing its policy, in violation of the Outer Space Treaty, of recklessly dumping rocket stages on others.

The leaders in the 2022 launch race:

41 SpaceX
37 China
11 Russia
6 Rocket Lab
5 ULA

American private enterprise still leads China 56 to 37 in the national rankings, but is now tied with the entire world combined 56 to 56. This tie will likely not be long-lived. Though Firefly’s launch has been delayed until next week, SpaceX and Rocket Lab have launches scheduled for today and tomorrow, respectively.

NASA revises its SLS launch schedule, pending approval of the range’s safety office

6:13 pm

NASA today announced that it is now targeting September 27, 2022 for the first test launch of its SLS rocket and Orion capsule.

Engineers have — on the launchpad — completed the repair work on the hydrogen leak that caused the previous launch scrubs. The plan now is to do a test fueling on September 21st to see if the repair worked.

If all is then well, the agency wants to launch on September 27th. To do so however NASA needs to get the approval of the safety range office to waive the use-by date of the batteries used to terminate the flight after launch, should something go seriously wrong. The rules require those batteries to be checked every 20 days, and as of today they have been in use for 31 days. The range had already given NASA a five day waiver so it could try to launch on September 5. To launch on September 27th will require the range to allow those batteries to remain unchecked for 46 days, more than double their accepted use-by date.

For the range to allow such a waiver would be I think entirely unprecedented, especially for the very first launch of a new rocket. Such test launches are exceedingly risky. A lot can go wrong, and often does when a rocket tries to fly for the first time. To allow such a lift-off with a questionable flight termination system seems completely insane and irrational.

NASA is also proposing an October 2nd launch date. I suspect this date is based on the range safety office refusing to give this waiver. If so, NASA would then do its September 21st fueling test on the launchpad, quickly roll the rocket back to the assembly building to check the batteries, and then try to get it back to the launch pad in time for that October 2nd date.

InSight’s power level goes up!

5:54 pm

InSight's power levels as of September 5, 2022

The most recent status update on the Mars lander InSight, released today, shows a slight rise in the amount of power generated by its dust-covered solar panels.

As shown on the graph to the right, on August 27, 2022 the power level was 400 watt-hours generated per Martian day. On September, 5, 2022, the power level was 410 watt-hours per Martian day, the first power increase since late July. At the same time, the dust in the atmosphere continued to clear, going from a tau level of .88 to 0.8. Outside of the winter dust season tau is usually between 0.6 and 0.7.

The slight power increase continues to suggest that the lander’s death might be delayed. At 400 watt-hours per day, it has been able to run its seismometer since the beginning of July. With this slight increase, the chance increases that InSight will finally get that one gust of wind or dust devil that will blow the dust off its solar panels and allow it to recover some power and operate for longer.
