  • Anonymous sources say NASA is considering restructuring the entire Artemis lunar program

    • One idea is to insert an extra mission before the lunar landing flight, during which Orion and Starship would dock in Earth orbit to test out their systems prior to going to the Moon. Since the whole Artemis program has always been haphazardly planned, this change makes sense, as it should have been considered from the beginning. In fact, it should be flown before the second Artemis flight, which presently intends to take astronauts around the Moon, on the first flight using Orion’s environmental systems.

Blue Origin completes delivery of the two BE-4 engines for ULA’s second Vulcan launch

10:04 am

Blue Origin this week completed delivery of the two BE-4 engines needed for the second launch of ULA’s Vulcan rocket, presently scheduled for sometime this fall.

That launch was originally targeting an April launch, but according to official announcements has been delayed until the fall because final ground testing of its payload, Sierra Space’s Tenacity mini-shuttle, is not complete. It appears that Blue Origin also contributed to that delay, as it is now obvious that its engines were not available as planned in time for that April launch.

This delay also raises questions about Blue Origin’s ability to ramp up BE-4 engine production to meet the needs of ULA’s Vulcan rocket and Blue Origin’s New Glenn rocket. Both have large launch contracts with Amazon to launch its Kuiper constellation, while ULA also has almost as many contracts with the U.S. military. To meet those contracts, Blue Origin will have to produce several hundred BE-4 engines yearly in the very near future. Right now it appears it can only produce about one per year.

Boeing to reduce staffing for SLS due to overall delays in Artemis

9:53 am

Boeing announced yesterday that it is going to reduce the staffing for its SLS rocket, caused by delays in other parts of the program that force it to stretch out operations.

When Boeing cites “external factors,” it is referring to the slipping timelines for NASA’s Artemis Program. In January officials with the space agency announced approximately one-year delays for both the Artemis II mission, a crewed lunar flyby, to September 2025; and Artemis III, a lunar landing, to September 2026. Neither of these schedules are set in stone, either. Further delays are possible for Artemis II, and likely for Artemis III if NASA sticks to the current mission plans.

Although the SLS rocket will be ready for the current schedule, barring a catastrophe, the other elements are in doubt. For Artemis II, NASA still has not cleared a heat shield issue with the Orion spacecraft. That must be resolved before the mission gets a green light to proceed next year. The challenges are even greater for Artemis III. For that mission NASA needs to have a lunar lander—which is being provided by SpaceX with its Starship vehicle—in addition to spacesuits provided by Axiom Space for the lunar surface. Both of these elements remain solidly in the development phase.

What Boeing is telling us indirectly is that, though NASA has not yet announced any further delays in those launch dates for Artemis-2 and Artemis-3, those dates are going to be delayed, quite possibly by one or more years.

None of this is a surprise. I have long been predicting that the first manned lunar landing in the Artemis program will not take place before 2030. In fact, that date was obvious the moment NASA announced its plan to make the Lunar Gateway space station an integral part of the program, back in 2018, when it was called LOP-G.

Now that SLS development is complete and NASA considers it “operational”, Boeing is merely reducing the staffing to maintain its assembly line, reducing it accordingly because of expected delays when additional rockets will be needed.

Analysis of Io’s atmosphere suggests it has been volcanically active for its entire 4+ billion year history

9:34 am

By analysizing the isotobes in Io’s atmosphere, scientists now believe that it has been volcanically active since its initial formation at the birth of the solar system 4.5 billion years ago.

de Kleer et al. found that both elements [ sulfer- and chlorine-bearing molecules] are highly enriched in heavy isotopes compared to average Solar System values due to the loss of lighter isotopes from the upper atmosphere as material is continuously recycled between Io’s interior and atmosphere. The findings indicate that Io has lost 94% to 99% of the sulfur that undergoes this outgassing and recycling process. According to the authors, this would require Io to have had its current level of volcanic activity for its entire lifetime.

This data suggests that Io, as well as Jupter’s other three large Galilean moons (Europa, Calisto, and Ganymeded) have been in their present orbits since their formation 4.5 billion years ago. It also means that, while Io’s geological history keeps getting wiped out by its volcanic activity, the other three contain detailed geological records of the solar system’s entire history. Combine that with the geological data we will eventually get from Mars, it appears that we shall someday be able to document that history far beyond anything expected.

Both tweets are devoid of any real information, so who knows? It is likely the second is real and happening, but there continue to be rumors about Blue Origin’s production rate.

FAA to now require that reentry spacecraft get landing license before launch

4:05 pm

We’re here to help you! The FAA is now going to require that any company planning to launch a payload or spacecraft into orbit to get both its launch and landing licenses before launch, in order to avoid the situation that occurred last year when Varda launched its capsule and then had difficulties getting its landing license approved due to red-tape confusion between government agencies.

In a notice published in the Federal Register April 17, the FAA’s Office of Commercial Space Transportation announced it will no longer approve the launch of spacecraft designed to reenter unless they already have a reentry license. The office said that it will, going forward, check that a spacecraft designed to return to Earth has a reentry license as part of the standard payload review process.

In the notice, the FAA said that decision was linked to safety concerns of allowing spacecraft to launch without approvals to return. “Unlike typical payloads designed to operate in outer space, a reentry vehicle has primary components that are designed to withstand reentry substantially intact and therefore have a near-guaranteed ground impact as a result of either a controlled reentry or a random reentry,” it states.

While this seems to fall directly under the FAA’s basic authority, to make sure launches and landings pose no risk to the general public, I guarantee it is also going to slow the growth of the new space manufacture industry. I fear that with time approvals will be delayed, some so much that companies will go bankrupt waiting for approval. The FAA will never be able to guarantee perfection in this matter, and as bureaucrats tend to be cautious, expect it to increasingly oppose re-entries by new companies.

Bunny march on! SpaceX today successfully launched another 23 Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral.

The first stage completed its seventh flight, landing successfully on a drone ship in the Atlantic.

The leaders in the 2024 launch race:

41 SpaceX
15 China
6 Russia
4 Rocket Lab

American private enterprise now leads the rest of the world combined 47 to 27, while SpaceX by itself now leads the rest of the world, including other American companies, 41 to 33.

Ancient flood lava in the Martian cratered highlands

Ancient flood lava on the cratered highlands of Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on February 4, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The ridges were the primary reason this photo was taken, as they cover a 50-mile-square region of relatively flat terrain that also appears to be a series of steps downward to the west. The dotted line on the picture indicates one of those steps downward, with the plain to the west of that line about 100 to 200 feet lower that the plain to the east.

My first guess was that these ridges might be inverted channels, but that really didn’t make sense considering their random nature completely divorced from the downward grade. Then I took a wider view, and came up with a better guess.

Today’s blacklisted American: Former Trump lawyer, already disbarred in California because he took Trump’s case, now blackballed by his banks

11:43 am

Banks blacklisting conservatives
What many banks are now doing to conservatives.

They’re coming for you next: John Eastman — a former Trump lawyer who was fired from a professorship, was banned from speaking at conferences and colleges, is being prosecuted by Fanni Willis in Georgia, and was then disbarred in California, all because he simply made a legal arguement in favor of Trump — has now been blackballed by his banks, USAA and Bank of America.

Bank of America alerted Eastman in September of 2023 that it would be closing his accounts, a letter obtained by the Daily Caller shows. Shortly thereafter, USAA notified Eastman in November that his two bank accounts with the company would be closed, a separate letter shows.

“And then two months later, we get a similar letter from USAA saying that they’ve decided that they’re going to close your account and they did like three weeks later,” Eastman told the Daily Caller. “And so that was where all of our automatic payments were coming out of, all our automatic deposits. So it was a real pain to shift everything. We had to get a new bank account opened and shift everything over.”

It is important to emphasize that Eastman has done nothing wrong. » Read more

Rocket startup Orbex raises another $16.7 million in private investment capital

9:28 am

The British rocket startup Orbex has raised another $16.7 million in private investment capital, bringing the total it has raised now to over $100 million.

It remains unclear when the company’s Prime rocket will complete its first launch. It now says it will have its rocket and launch facility at the Sutherland spaceport ready by the end of this year, but it had previously hoped to launch the rocket in 2023. It appears that goal failed because the spaceport could not get either the spaceport license or its own launch license approved by the UK’s Civil Aviation Authority (CAA). Those licenses have still not been issued, even though the applications had been submitted in Feburary 2022, more than two years ago.

Those delays by the CAA probably explains why the company has had four different CEO’s in the past year. Though the fault of the delays lies with the government, others have had to take the blame. Meanwhile, company officials now state that it is now exploring using other launch sites, including its own near the equator.

TESS has resumed science operations

9:15 am

Engineers have successfully returned TESS to full science operations, without providing as yet any explanaton as to why on April 8, 2024 it went into safe mode or what they did to fix the issue.

The Aprill 11 press release announcing the safe mode had only mentioned that the shut down had occurred “during scheduled engineering activities.” The lack of information continues to suggest that someone did an “Oops!” during those activities, and NASA is too embarassed to reveal that fact.
