Senate schedules vote for confirming Jared Isaacman as NASA administrator

The Senate is now targeting early June for its vote on Jared Isaacman’s nomination as NASA administrator.

Senate Majority Leader John Thune (R-S.D.) filed cloture on Isaacman’s nomination May 22, a procedural move that would set up a vote on the nomination in early June. The Senate is not in session the week of May 26 because of the Memorial Day holiday.

Since his nomination was approved by the Senate Commerce committee in April, Isaacman has been meeting with many other senators. The article at the link does the typical mainstream press thing of pushing back 100% against the proposed NASA cuts put forth by Trump’s 2026 budget proposal, telling us that these senators were generally opposed to those cuts and questioning Isaacman about them, a claim not yet confirmed. It did note something about those senators and those proposed cuts that if true was very startling and possibly very encouraging.

While many of the proposals in the budget, like winding down SLS and Orion, were expected, the scale of the cuts, including a nearly 25% overall reduction in NASA spending, still took many by surprise. [emphasis mine]

In other words, Congress was not surprised by the proposed end of SLS and Orion. It even appears they are ready to give it their stamp of approval.

None of this is confirmed, so take my speculation with a grain of salt. Still, the winds do appear to be blowing against SLS and Orion.

Europe and India sign agreement to work together on manned space flight

The European Space Agency (ESA) yesterday announced that it has signed an agreement with the Indian government that will lay the groundwork for them to work together on manned space exploration, first in connection with their future space station plans and later on lunar exploration.

ESA and ISRO declared their intent to work together on the interoperability of rendezvous and docking systems to allow their respective spacecraft to work together in low Earth orbit. They will also examine further activities related to astronaut training, analogue space missions – where teams test aspects of space missions in ground-based simulations – and parabolic flight activities.

…Future cooperation possibilities include ESA astronaut flight opportunities to the planned Bharatiya Antariksh Station (BAS) and early scientific utilisation, as well as developing infrastructure in low Earth orbit. The two space agencies are also discussing alignment on payloads and robotic scientific missions to the Moon.

Faced with the decommissioning of ISS in 2030, as well as the likely end to several major Artemis components (Orion and Lunar Gateway) that ESA has had a major part, it appears Europe has quickly begun looking for other alternatives. It already has partnered with the American consortium building the Starlab space station, but this new agreement with India gives it more options.

India meanwhile gets aid and support from Europe. It could even be that both are negotiating transferring some of Europe’s Lunar Gateway modules to India’s space station.

ESA’s issues a non-reaction to Trump’s proposed NASA cuts

The European Space Agency (ESA) yesterday issued its first reaction to Trump’s proposed cuts to NASA’s Artemis program, including cancellation of the Orion capsule and Lunar Gateway station that ESA is building major components, and essentially said nothing.

NASA has briefed ESA about the Budget Request, and while some questions still remain about the full repercussions, follow-up meetings are already taking place with NASA. ESA remains open to cooperation with NASA on the programmes earmarked for a reduction or termination but is nevertheless assessing the impact with our Member States in preparation for ESA’s June Council.

ESA and NASA have a long history of successful partnership, particularly in exploration – a highly visible example of international cooperation – where we have many joint activities forging decades of strong bonds between American and European colleagues. Space exploration is an endeavour in which the collective can reach much farther than the individual. Thus, ESA has strong partnerships with space agencies from around the globe and is committed to not only being a reliable partner, but a strong and desirable partner.

Basically ESA is holding off any major response until they get more information from NASA and the Trump administration. It also notes that any more detailed response must wait until it holds its own meetings scheduled for June and later.

ESA’s problem is that it tied its manned space effort to NASA’s Orion capsule and Gateway station. On Orion it is building the service module, and has a number under construction that now might be unneeded if only two more Orions fly. As for Gateway, Europe is building major components of the station’s central habitation module. It is also building, in partnership with Japan, a second habitation module for their use. The cancellation of Gateway leaves these modules hanging with nowhere to go.

Though we should expect some pushback from Europe in an attempt to save Lunar Gateway, I expect these events will end up doing more for Europe’s nascent commercial launch industry. What the continent really needs is a private competitive aerospace industry making money in space. If it gets that, it will no longer have to rely on NASA, or ESA for that matter.

And based on the recent policy actions by ESA’s major partners (Germany, France, Italy, Spain, and the UK) to shift from a government-run centralized space program run by ESA’s Arianespace to encouraging the development of an independent competing private launch industry, I predict Europe will shift even more focus in this direction when they finally respond to the Trump cuts.

Expect European to call for more autonomy and European-built rockets and spacecrafts that do not rely on NASA or American proposals. This will not necessarily end its space partnership with the U.S., but it will be less beholden to it.

It only took $22 billion and 19 years: Lockheed Martin proudly announces the completion of the first Orion capsule capable of manned flight

Orion's damage heat shield
Damage to Orion’s heat shield caused during re-entry in 2022,
including “cavities resulting from the loss of large chunks”.
Nor has this issue been fixed.

My heart be still. On May 1, 2025 Lockheed Martin proudly announced that it had finally completed assembly and testing of the first Orion capsule capable of taking human beings into space.

Lockheed Martin [NYSE: LMT] has completed assembly and testing of NASA’s Orion Artemis II spacecraft, transferring possession to NASA’s Exploration Ground Systems (EGS) team today. This milestone is a significant step for NASA and the Artemis industry team, as they prepare to launch a crew of four astronauts to further the agency’s mission in establishing a human presence on the Moon for exploration and scientific discovery. It will also help build the foundation for the first crewed missions to Mars.

Orion is the most advanced, human-rated, deep space spacecraft ever developed. Lockheed Martin is the prime contractor to NASA for Orion and built the crew module, crew module adaptor and launch abort system. “This achievement is a testament to our employees and suppliers who have worked tirelessly to get us to this important milestone,” said Kirk Shireman, vice president of Human Space Exploration and Orion program manager at Lockheed Martin. “The Orion spacecraft completion for Artemis II is a major step forward in our nation’s efforts to develop a long-term lunar presence. It’s exciting to think that soon, humans will see the Earth rise over the lunar horizon from our vehicle, while also traveling farther from Earth than ever before.”

What disgusting hogwash. First of all, Lockheed Martin was issued the contract to build two capsules, one for testing and one for manned flight, in 2006. It only took the company 19 years to build both. Second, that 2006 contract was supposed to only cost $3.9 billion. Instead, NASA has forked out more than $22 billion.

And what have we gotten? Two capsules, plus a handful of prototype test versions. Worse, this first capsule will be the first to ever carry the life support systems that keep humans alive, as Lockheed Martin admits in its press release:

Congress: Let’s throw some more astronaut lives away so we can preen for the camera!

Jared Isaacman
Jared Isaacman

Here we go again: As I noted yesterday, the hearing this week of Jared Isaacman, Donald Trump’s nomination to become NASA’s next administrator, revealed almost nothing about what Isaacman plans to do once confirmed by the Senate. He very carefully kept his options open, even while he strongly endorsed getting Americans on the Moon as fast as possible in order to beat the Chinese there. When pressed by senators from both parties to commit to continuing the SLS, Orion, and Lunar Gateway projects to make that happen, Isaacman picked his words most cautiously. He noted that at the moment that plan seemed the best for getting to the Moon first. He also noted repeatedly that this same plan is years behind schedule and overbudget.

Like any smart businessman, Isaacman knows he cannot make any final decisions about SLS, Orion, or Gateway until he takes office and can aggressively dig into the facts, as administrator. He also knew he could not say so directly during this hearing, for to do so would antagonize senators from both parties who want those programs continued because of the money it pours into their states. So he played it coy, and the senators accepted that coyness in order to make believe they were getting what they want.

But what do these senators want? It appears our politicians (including possibly Trump) want NASA to launch humans to the Moon using SLS and Orion and do so as quickly as possible, despite knowing that both have real engineering issues of great concern. Instead, our elected officials want politics to determine the lunar flight schedule, instead of engineering, the same attitude that killed astronauts on Apollo 1 in 1967, on Challenger in 1986, and on Columbia in 2003. The engineering data then said unequivocally that things were not safe and that disaster was almost guaranteed, but NASA and Congress demanded the flights go on anyway, to serve the needs of politics.

With SLS and Orion it is now the same foolishness all over again. » Read more

Boeing notifies SLS employees of impending layoffs

The real cost of SLS and Orion
The expected real per launch cost of SLS and Orion

Boeing yesterday sent a notice out to its employees working on NASA’s SLS rocket that up 400 could be laid off due to “revisions to the Artemis program and cost expectations.”

Boeing SLS employees were informed Feb. 7 that the company was making preparations to cut up to 400 jobs from the program because of “revisions to the Artemis program and cost expectations.” The specific positions being considered for elimination were not announced but would account for a significant fraction of the overall SLS workforce at the company.

This is probably the most significant update from the entire SLS program since it was first proposed by George Bush Jr in 2004. All other announcements either told us there were going to be more delays, the cost was going up, or there were newly discovered technical problems caused by bad management or sloppy work. This announcement instead actually indicates that NASA management — under pressure from the new Trump administration — is finally addressing these failures after two decades.

In the past few months there have been many indications from the swamp in Washington that it is finally beginning to recognize the absurdity and stupidity of the whole SLS/Orion infrastructure, a realization I outlined in detail fourteen years ago, soon after the project was reshaped from the absurd and stupid Ares project under Bush Jr. to SLS/Orion under Obama.

It took however the arrival of Trump (changed himself from his first administration) to do it. Trump is doing what no president has done in our lifetimes, going through all federal programs and ripping them apart if they are failing to do what they promise. And he is doing it with full and amazingly enthusiastic support of the American people. No one cares that government employees are “crying.” Nor does anyone pay attention any longer to these sob stories, put out by the propaganda press. It have proven itself to be habitual liars whose only interest has been prop up the Washington swamp, and everyone now recognizes it.

Expect a major reshaping of NASA and its entire manned program. We will still be heading to the stars, but finally doing it.

More evidence SLS and Orion are on the way out

An article today by a local Fox station in Orlando calling NASA’s decision to fly the next Artemis mission using the Orion capsule as a return to the bad culture that caused both shuttle accidents is strong evidence that the political winds are now definitely blowing against the future of both NASA’s SLS rocket and its Orion capsule.

The article interviews former NASA astronaut Charles Camarda, who expressed strong reservations about NASA’s willingness to make believe the failures of the Orion heat shield on its only test flight could be dismissed.

“The way they’re attacking the problem is echoes of Challenger and Columbia, using exactly the same bad behaviors to understand the physics of the problem,” [former astronaut Charles Camarda] said. “They’re not using a research-based approach.” Camarda worries NASA is pressing ahead with the current heat shields because he says “a lot of the engineers are afraid to speak up, and that’s a serious problem.”

The point is not the article itself, but that a mainstream propaganda news outlet is publishing this perspective. This fact suggests that there is a growing willingness within the political community to end both SLS and Orion, and articles such as this are used to strengthen that narrative. Politicos in DC have a great fear of canceling big projects, and for them to agree to do so requires a great deal of groundwork to make sure the public will accept the decision. Articles such as this one are thus published in the propaganda press for exactly this reason.

In other words, the Washington swamp has now begun its own campaign to cancel SLS and Orion.

Why Orion’s heat shield problems give Jared Isaacman the perfect justification to cancel all of SLS/Orion

Orion's damage heat shield
Damage to Orion heat shield caused during re-entry in 2022,
including “cavities resulting from the loss of large chunks”

In yesterday’s press conference announcing new delays in NASA’s next two SLS/Orion Artemis missions to the Moon, agency officials were remarkably terse in providing details on why large chunks of Orion’s heat shield material broke off during its return to Earth in 2022 during the first Artemis mission. That damage, shown to the right, is one of the main reasons for the newly announced launch delays.

All they really said was that the damage was caused during re-entry, the atmosphere causing more stress than expected on the heat shield.

Today NASA finally released a more detailed explanation.

Engineers determined as Orion was returning from its uncrewed mission around the Moon, gases generated inside the heat shield’s ablative outer material called Avcoat were not able to vent and dissipate as expected. This allowed pressure to build up and cracking to occur, causing some charred material to break off in several locations.

…During Artemis I, engineers used the skip guidance entry technique to return Orion to Earth. … Using this maneuver, Orion dipped into the upper part of Earth’s atmosphere and used atmospheric drag to slow down. Orion then used the aerodynamic lift of the capsule to skip back out of the atmosphere, then reenter for final descent under parachutes to splashdown.

[Ground testing during the investigation showed] that during the period between dips into the atmosphere, heating rates decreased, and thermal energy accumulated inside the heat shield’s Avcoat material. This led to the accumulation of gases that are part of the expected ablation process. Because the Avcoat did not have “permeability,” internal pressure built up, and led to cracking and uneven shedding of the outer layer.

In other words, instead of ablating off in small layers, the gas build-up caused the Avcoat to break off in large chunks, with the breakage tending to occur at the seams between sections of the heat shield.

Next two Artemis missions delayed again, with the future of SLS/Orion hanging by a thread

Orion's damage heat shield
Damage to Orion heat shield caused during re-entry in 2022,
including “cavities resulting from the loss of large chunks”

In a press conference today, NASA officials admitted that their present schedule for the next two Artemis missions will not be possible, and have delayed the next mission (sending four astronauts around the Moon) from the end of 2025 to April 2026, and the next mission (landing astronauts on the Moon) to a year later.

It must be noted that when first proposed by George Bush Jr in 2004, he targeted 2015 for this manned landing. Should the present schedule take place as planned, that landing will now occur more a dozen years late, and almost a quarter century after it was proposed. We could have fought World War II six times over during that time.

Several technical details revealed during the conference:

  • It appears a redesign of Orion’s heat shield will take place, but not until the lunar landing mission. For Artemis-2 (the next flight), engineers have determined they can make the shield work safely by changing the re-entry path. They have also determined that the design itself is still insufficient, and will require redesign before Artemis-3.
  • Though Orion’s life support system will still be flown for the first time on Artemis-2, the first to carry humans, they have been doing extensive ground testing and have resolved a number of issues. They are thus confident that it will be safe to fly with people on its first flight.
  • Though SLS’s two solid-fueled strap-on boosters will be stacked for more than one year when Artemis-2 launches in April 2026, they are confident based on data from Artemis-1 that both will still be safe to use.

The political ramifications that lurked behind everything however are more significant.

Trump picks billionaire and private astronaut Jared Isaacman to run NASA

Jared Isaacman
Jared Isaacman

Capitalism in space: In a decision that is certain to send shock waves throughout NASA and the established aerospace industry, President-elect Donald Trump today announced that he has chosen billionaire and private astronaut Jared Isaacman to be his nominee for NASA administrator.

Isaacman quickly accepted the nomination.

Besides being a jet pilot with extensive experience in the aerospace industry, Isaacman has also commanded two space missions, financed out of his own pocket. Both missions used SpaceX’s Falcon 9 rocket and Resilience capsule. Both also pointedly avoided any involvement with NASA, spending several days in free Earth orbit instead of docking with ISS. The second mission achieved several major engineering milestones, testing the first privately built spacesuit during a spacewalk while also flying farthest from Earth since the 1970s Apollo missions.

These flights were part of Isaacman’s own long term space program, dubbed Polaris, with two more missions already in planning stages. The first would be another Dragon orbital mission in which Isaacman had tried to get NASA to shape as a Hubble repair mission. NASA declined. The second is intended as a manned mission around the Moon using SpaceX’s Starship.

That program will now likely get folded into NASA’s Artemis program, which we can all expect Isaacman to force major changes. For one thing, this is another blow to the future of SLS and Orion. As a very successful businessman Isaacman will look with great skepticism at this boondoggle.

For another, Isaacman’s markedly different experiences working with SpaceX versus NASA will likely encourage major bureaucratic changes at the space agency. It is almost certain that Isaacman’s manned flights avoided ISS in order to avoid its Byzantine red tape, that would have likely also blocked use of SpaceX’s spacesuit on a private spacewalk. NASA’s decision to reject Isaacman’s proposal to do a simple but very necessary Hubble repair mission will also likely influence his management of the agency. Isaacman is going to force NASA to depend on the private sector more. He is also likely to reduce the agency’s risk adverse mentality that while often reasonable is many times very counter-productive.

Unlike many of Trump’s other radical nominees, I would be very surprised if Isaacman is not confirmed quickly and with little opposition.

Whether Isaacman will still fly his two remaining private Polaris manned missions is at this moment unknown. Practically it would make sense to cancel them, since he will have much bigger fish to fry at NASA. Emotionally and politically however it would be truly spectacular to have NASA’s administrator fly in space, on a mission using no taxpayer funds. That more than anything would demonstrate the ability of freedom and private enterprise to get things done.

NASA once again gambling on the lives of its astronauts for political reasons

Orion's damage heat shield
Damage to Orion heat shield caused during re-entry in 2022,
including “cavities resulting from the loss of large chunks”

NASA this week began the stacking one of the two strap-on solid-fueled boosters that will help power SLS on the Artemis-3 mission, still officially scheduled for September 2025 and aiming to send four astronauts around the Moon.

A NASA spokesperson told Ars it should take around four months to fully stack the SLS rocket for Artemis II. First, teams will stack the two solid-fueled boosters piece by piece, then place the core stage in between the boosters. Then, technicians will install a cone-shaped adapter on top of the core stage and finally hoist the interim cryogenic propulsion stage, or upper stage, to complete the assembly.

At that point the rocket will be ready for the integration of the manned Orion capsule on top.

The article at the link sees this stacking as a good sign that NASA’s has solved the Orion capsule’s heat shield issue that occurred during the unmanned return from the Moon on the second Artemis mission. The image to the right shows that heat shield afterward, with large chunks missing. Though it landed safely, the damage was much much worse than expected. At the moment NASA officials have said it has found the root cause, but those officials also refuse to say what that root cause is, nor how the agency or Orion’s contractor Lockheed Martin has fixed it.

The dim future of SLS indicated at space business symposium

At a symposium in DC yesterday, a panel of past managers — all of whom had been involved in previous government transitions at NASA — attempted to predict what the consequences will be for NASA with the new Trump administration.

Most of the opinions were pure guesses, some better than others. The real moment of truth came when the entire panel was asked to predict the future of SLS and Orion. The question was put forth by one of the panelists, Lori Garver, who had been NASA’s deputy administrator during the Obama administration, and seemed to have the best understanding of how much the arrival of Trump will likely shake things up significantly.

At one point in the discussion, she asked the panel if they thought the Space Launch System and Orion programs would continue in the next administration. None of the panelists raised their hands. [emphasis mine]

Several of these panelists were big supporters of SLS. Their lack of confidence in its future tells us that SLS and Orion no longer have strong political backing in Washington. Both stand on thin ice.

I predict both will be shut down within the next year, before the next Artemis flight, the first to be manned, to be replaced with a entirely different manned space exploratory program to the Moon and Mars. The decision will be a smart one, but tragically late in coming. SLS should have been dumped years ago. If it had, the U.S. effort to return to the Moon would have been better off, moving forward with a better plan years earlier. Instead, this late decision will once again delay any manned lunar missions for years more.

The change however will be good in the long run, because I expect the new program will be better designed, more efficient, cost less, and be able to do what SLS promised but could never deliver. And it will be based on what private enterprise can accomplish, not a government designed behemoth designed mostly as pork.

NASA IG: NASA’s effort to build new SLS mobile launcher is an epic disaster

SLS's two mobile launchers, costing $1 billion
NASA’s bloated SLS mobile launchers

According to a new report [pdf] from NASA’s inspector general, both NASA and its contractor Bechtel have allowed the cost and schedule for the new larger SLS mobile launcher (ML-2) (on the right in the graphic) to go completely out of control, with the first launch on that platform to be delayed again until 2029.

NASA projects the ML-2 will cost over three times more than planned. In 2019, NASA estimated the entire ML-2 project from design through construction would cost under $500 million with construction completed and the ML-2 delivered to NASA by March 2023. In December 2023, NASA estimated the ML-2 project would cost $1.5 billion, including $1.3 billion for the Bechtel contract and $168 million for other project costs, with delivery of the launcher to NASA in November 2026. In June 2024, NASA established the Agency Baseline Commitment (ABC)—the cost and schedule baseline committed to Congress against which a project is measured—for a ML-2 project cost of $1.8 billion and a delivery date of September 2027. Even with the establishment of the ABC, NASA intends to keep Bechtel accountable to the cost and schedule agreed to in December 2023.

Despite the Agency’s increased cost projections, our analysis indicates costs could be even higher due in part to the significant amount of construction work that remains. Specifically, our projections indicate the total cost could reach $2.7 billion by the time Bechtel delivers the ML-2 to NASA. With the time NASA requires after delivery to prepare the launcher, we project the ML-2 will not be ready to support a launch until spring 2029, surpassing the planned September2028 Artemis IV launch date.

This quote actually makes things sounder better than they are. Bechtel’s original contract was for $383 million, which means the IG’s present final estimate of $2.7 billion is more than seven times higher. The contract was awarded in 2019 and was supposed to be completed by 2023, in four years. Instead, at best it will take Bechtel a decade to complete the job.

The IG notes that this contact was cost-plus, and considers this the main cause of these cost overruns. It also notes that NASA has had the option to convert the contract to fixed-price, but has chosen not to do so.

Possibly the most damning aspect of the IG report is its conclusion, which essentially admits that nothing can be done to fix this problem.

First SLS/Orion manned mission faces new delays because of Orion heat shield issues

Orion's damage heat shield
Damage to Orion heat shield caused during re-entry in 2022,
including “cavities resulting from the loss of large chunks”

Because the damage to the heat shield on the Orion capsule that flew around the Moon in late 2022 remains somewhat unexplained, NASA is considering delaying the next SLS/Orion mission, presently planned for September 2025 and intended to be the first Artemis flight to carry humans and take them around the Moon.

The heat shield, already installed at the base of the Orion spacecraft, will take the brunt of the heating when the capsule blazes through Earth’s atmosphere at the end of the 10-day mission. On the Artemis I test flight in late 2022, NASA sent an Orion spacecraft to the Moon and back without a crew aboard. The only significant blemish on the test flight was a finding that charred chunks of the heat shield unexpectedly stripped away from the capsule during reentry as temperatures increased to nearly 5,000° Fahrenheit (2,760° Celsius).

The spacecraft safely splashed down, and if any astronauts had been aboard, they would have been fine. However, the inspections of the recovered spacecraft showed divots of heat shield material were missing.

Two years later, despite extensive investigation and analysis, it appears NASA has not yet identified the root cause of the damage. The ablative material used on Orion was similar (though not identical) to the material used successfully on numerous other heat shields since the 1960s, yet it did not perform as expected.

NASA is presently facing three options. Do nothing and fly the next mission as planned, with four astronauts. It could rethink the trajectory used during re-entry, though this would likely not change things significantly unless the astronauts don’t go around the Moon as planned. Or it could change the heat shield itself.

The first two options are very risky, considering the unknowns. The latter involves a major delay of at least two years.

A decision must be made soon however. To meet the agency’s schedule it must begin stacking SLS’s two solid-fueled strap-on boosters next month. Those boosters have a limited life expectancy originally estimated to be one year. In the first unmanned Artemis test flight in 2022, NASA because of other delays stretched that life span to two years, and had no problems with the launch. If it stacks the boosters now and then has to delay for two more years to redesign Orion’s heat shield, those boosters will have been stacked for three years when launched.

Considering how seriously NASA is taking the issues with Starliner, which are likely not as serious as a heat shield that doesn’t work reliably, it would seem insane for NASA to launch Orion manned without fixing its own problem. And yet, for more than two decades NASA has consistently not demanded the same safety standards for SLS that it has demanded for the private commercial rocket startups. We shall see if this pattern now persists.

I continue to believe that the first Artemis lunar landing will not take place before 2030 (at least six years behind schedule). This heat shield dilemma only strengthens that prediction.

NASA IG: Major technical problems with Orion remain unsolved

Orion's damage heat shield
Damage to Orion heat shield caused during re-entry,
including “cavities resulting from the loss of large chunks”

A just released report [pdf] by NASA’s inspector general has found the major technical problems discovered after the first unmanned Artemis mission of Orion around the Moon remain unsolved, and threaten the safety of the astronauts that NASA plans to send around the Moon on the second Artemis mission.

The problems with Orion are threefold and are quite serious, involving its heat shield, separation bolts, and power distribution.

Specifically, NASA identified more than 100 locations where ablative thermal protective material from Orion’s heat shield wore away differently than expected during reentry into Earth’s atmosphere. Engineers are concurrently investigating ways to mitigate the char loss by modifying the heat shield’s design or altering Orion’s reentry trajectory.

In addition, post-flight inspections of the Crew Module/Service Module separation bolts revealed unexpected melting and erosion that created a gap leading to increased heating inside the bolt. To mitigate the issue for Artemis II, the Orion Program made minor modifications to the separation bolt design and added additional thermal protective barrier material in the bolt gaps.

NASA also recorded 24 instances of power distribution anomalies in Orion’s Electrical PowerSystem. While NASA has determined that radiation was the root cause and is making software changes and developing operational workarounds for Artemis II, without a permanent hardware fix, there is increased risk that further power distribution anomalies could lead to a loss of redundancy, inadequate power, and potential loss of vehicle propulsion and pressurization.

Moreover, like with any engineering system, without understanding the residual effects of introducing design and operational changes, it will be difficult for the Agency to ensure that the mitigations or hardware changes adopted will effectively reduce the risks to astronaut safety.

This is not all.

Technical issues with Lockheed Martin’s Orion capsule to delay next Artemis mission

It appears that technical issues with Lockheed Martin’s Orion capsule are one of the main reasons NASA has had to delay next Artemis mission, the first to put humans inside that capsule and then take them around the Moon.

In January 2024 it was reported that the mission would be delayed from a launch before the end of 2024 until 2025. We now know why:

NASA is working with Orion spacecraft prime contractor Lockheed Martin to resolve a handful of issues that came up late last year during ground testing, forcing the space agency to delay the launch readiness target date for its Artemis II circumlunar mission to September 2025. The Lockheed Martin assembly, test, and launch operations (ATLO) team at Kennedy Space Center (KSC) is reinstalling some electronics and implementing workarounds for others affected by an electrical circuit flaw found in digital motor controllers on the spacecraft.

While a resolution to that issue appears to be getting closer, the Orion program and contractor teams are also working through the corrective actions process for a problem with how the Orion batteries handle the shock of an extreme abort case.

In other words, Lockheed Martin discovered these two electrical issues only last year, after spending almost two decades and more than $15 billion developing Orion.

As I predicted in January, “None of these dates will be met. I predict that further delays will be announced next year and the year after that, pushing all these missions back again, in small increments.” I also predicted that NASA will be lucky to land a human on the Moon by 2030, a mere fifteen years after its original target date of 2015, set by George Bush Jr. in 2004.

In the meantime, expect SpaceX’s Starship to begin regularly commercial and governmental flights to the Moon in the next five years. Long before SLS and Orion put humans on the Moon, Starship will be doing it privately for less cost.

NASA makes it official: The entire Artemis schedule is delayed

Surprise! NASA yesterday officially confirmed the rumors reported earlier about delays in its Artemis Moon program, outlining a new schedule that pushes all the launches back from months to more than a year.

NASA will now target September 2025 for Artemis II, the first crewed Artemis mission around the Moon, and September 2026 for Artemis III, which is planned to land the first astronauts near the lunar South Pole. Artemis IV, the first mission to the Gateway lunar space station, remains on track for 2028.

The agency cited issues with its Orion capsule that need fixing, including unexpected damage to its heat shield during the first test flight in 2022, battery problems found during ground testing, and new issues discovered with the as-yet unflown environmental systems designed to keep the astronauts alive.

One rumor that did not turn out to be true was the suggestion that first manned lunar landing would be shifted from Artemis 3 to Artemis 4, to give NASA more time to test things.

More details about the press briefing can be found here.

No one should take any of these dates seriously. NASA technique for announcing delays in this moon program have consistently been wrong. It announces small delays incrementally, to hide the fact that it knows the actual launch will be delayed far more that politics allows. The program was first proposed in 2004 with a planned landing in 2015. Since then NASA has announced numerous delays numerous times, always in small amounts. Yet by 2015 it was clear the first landing wouldn’t happen for at least a decade (after a decade of work), because of Obama’s unilateral cancellation of the initial program and Congress’s demand that it be re-established in a different form. By 2022 it was clear that the first manned landing mission was at least five years away.

Thus these new dates will certainly slip. You can bet on it. As I noted yesterday, NASA will be lucky to make that first manned lunar landing by 2030.

Japan & NASA negotiating plan to put Japanese astronaut on later Moon landing mission

According to the Japanese press, Japanese and American government officials are negotiating a plan to include a Japanese astronaut on one of the later Artemis Moon landing missions, presently hoping to fly in the late 2020s.

Japan has been negotiating with the United States, aiming for its first landing on the moon in the late 2020s. Tokyo and Washington will establish and sign an agreement on the activities of Japanese astronauts on the moon as early as next month, according to several government sources.

These stories are likely linked to the blather from Vice President Harris last week saying the U.S. will fly an international astronaut to the Moon before the end of the decade. At the time NASA officials would not confirm her statement, other than to say that NASA had agreed to fly European, Canadian, and Japanese astronauts to its Lunar Gateway station as part of its Artemis lunar program.

Several important details must be noted. First, the schedule for Artemis, as designed by NASA using SLS, Orion, Lunar Gateway, and Starship, is incredibly optimistic. The first manned mission is presently scheduled for 2025, but no one believes that date, including many at NASA. It will likely slip to 2026 or even 2027.

Second, the program is very fluid, and could undergo major changes with a new administration, especially because of the high cost of SLS. Once Starship/Superheavy is flying, at a cost expected to less than 1% of SLS, with an ability to fly frequently instead of once every two or three years, a new government might scrap the entire Artemis program as designed. A shift from SLS to Starship entirely might actually increase the number of astronauts going to the Moon, both from the U.S. and the entire Artemis Accords alliance.

NASA engineers still struggling to understand why Orion’s heat shield ablated so much

NASA engineers still do not understand why the heat shield on its Orion capsule ablated as it did during its return to Earth on the first unmanned Artemis-1 mission.

The agency is still running tests. It also expressed confidence that the issue will not delay the Artemis-2 mission, the first intended to carry humans on SLS and in Orion and still scheduled for late 2024.

At the same time, agency officials hinted that the third Artemis mission, which has always been planned as putting humans on the Moon for the first time since Apollo, might not achieve that goal. It is still not clear whether the mission’s lunar spacesuits as well as SpaceX’s Starship lunar lander will be ready on time. The latter is facing serious regulatory problems imposed by the Biden administration that is generally preventing it from flight testing the spacecraft.

That second Artemis mission, the first planned to carry humans, is one that actually at present carries the most risk. It will not only use a heat shield that at present engineers do not entirely understand, it will be the first Orion capsule to have the environmental systems necessary for its human cargo. NASA is putting humans on the first test flight of those systems.

ESA transfers its Artemis-2 Orion service module to NASA

The European Space Agency (ESA) yesterday officially handed over to NASA its second completed Orion service module, to be used in 2024 on the first manned Artemis mission, dubbed Artemis-2, that will carry four astronauts on a mission around the Moon.

The European Service Module-2 will power the Orion spacecraft on the Artemis II mission that will see NASA astronauts commander Reid Wiseman, pilot Victor Glover, and mission specialists Christina Koch with Canadian Space Agency astronaut Jeremy Hansen complete flyby of the Moon and return to Earth.

The crew will fly Orion to 8889 km beyond the Moon before completing a lunar flyby and returning to Earth. The mission will take a minimum of eight days and will collect valuable flight test data, in the first time for over 50 years that humans have voyaged to our natural satellite.

The odds of this launching in 2024 are relatively slim. It will also be the first time NASA will be flying Orion’s environmental systems (the systems that keep the astronauts alive). We all hope those system work perfectly this first time, since people will be on board.

NASA inspector general finds more cost overruns in the agency’s SLS rocket program

Surprise! Surprise! A new NASA inspector general report [pdf] has found that the agency’s SLS rocket program is continuing to experience cost overruns and mismanagement that are “obscene”, as noted in this news report.

An independent report published Thursday contained troubling findings about the money spent by the agency on propulsion for the Space Launch System rocket. Moreover, the report by NASA Inspector General Paul Martin warns that if these costs are not controlled, it could jeopardize plans to return to the Moon.

Bluntly, Martin wrote that if the agency does not rein in spending, “NASA and its contracts will continue to exceed planned cost and schedule, resulting in a reduced availability of funds, delayed launches, and the erosion of the public’s trust in the agency’s ability to responsibly spend taxpayer money and meet mission goals and objectives—including returning humans safely to the Moon.”

Things are really much worse than this, mostly because it appears the Marshall Space Flight Center that runs the SLS program for NASA uses cost-plus contracts, which are essentially a blank check for contractors to run up costs endlessly, all of which the government must cover, and allows the process to go over-schedule against its own regulations. Furthermore, the cost overruns are for rockets and engines that are not newly developed, but in use for decades by Northrop Grumman and Aerojet Rocketdyne.

Note that this really isn’t news. Anyone with any intellectual honesty at all will know that every aspect of SLS and Orion is mismanaged and will go over budget and behind schedule endlessly. These problems are not a bug, however, but a feature of the system. The goals of SLS and Orion are not really to build a rocket to explore the solar system but to create an endless jobs program in congressional districts here on Earth. This misguided approach meanwhile robs America of a viable space effort because the money wasted could have actually been used to jumpstart a viable and competitive space-faring economy that actually achieves something.

Aerojet Rocketdyne wins contract from Lockheed Martin to build more Orion engines

Aerojet Rocketdyne announced yesterday that it has been awarded a new $67 million contract from Lockheed Martin to build the Orion propulsion engines for Artemis missions six though eight.

This contract option includes delivery of three additional sets of Orion’s service module auxiliary engines and three additional jettison motors. The eight auxiliary engines each produce 105 pounds of thrust to help maintain Orion’s in-space trajectory and position, and supplement the Orion Main Engine. The jettison motor, located on Orion’s Launch Abort System (LAS), generates 40,000 pounds of thrust to separate the LAS from the crew module during both nominal operations and abort scenarios, allowing the spacecraft to continue on its journey. The jettison motor is the only motor on the LAS that fires during every mission.

These Artemis missions are not expected to occur until very late in this decade, by which time Starship will likely be making regular commercial trips to the Moon. At that time Orion will look increasingly ridiculous next to Starship, and will demonstrate starkly the difference in what government can do versus a free private sector.

Post-Artemis-1 report: heat shield ablated more than expected; power system issued unexpected commands; damage to launchpad

In a March 7, 2023 briefing, NASA officials provided an overall report of what happened during the first SLS launch, noting that there were some minor engineering issues but none that appeared to them significant.

The biggest issue of note was the Orion heat shield.

Howard Hu, Orion program manager at NASA, said that material on the heat shield had ablated differently than what engineers expected from ground tests and computer models. “We had more liberation of the charred material during reentry than we had expected,” he said. Engineers are just beginning detailed analysis of the heat shield to determine why it behaved differently than expected.

The amount ablated was well within safety margins, but engineers still do not understand why the material behaved differently than expected.

Engineers are also trying to understand why the power system of the Orion service module issued unplanned commands, several times opening what officials called a “latching current limiter.” This action caused no problems to the capsule’s operations, but it is concerning it occurred.

The launch also did more damage to the mobile launcher tower than expected.

According to NASA officials, none of these issues will delay the planned November 2024 launch date for the Artemis-2 mission, the first intended to carry humans.

Orion successfully splashes down in the Pacific

NASA’s Orion capsule today successfully returned from a three week trip around the Moon, splashing down in the Pacific where it was successfully recovered.

The next Artemis flight will be a manned one, using SLS and Orion to fly around the Moon. It will also be the first time Orion will use its full environmental system, with humans on board. Though presently scheduled for May 2024, it is almost certainly not going to fly before 2025.

The actual Artemis manned lunar landing will follow, no sooner than two years after that. As presently designed, that mission requires the establishment of the Lunar Gateway station — astronauts can be transferred from Orion to Starship and back again, and that station is likely not going to be ready in this time frame.

As I said yesterday, I predict the two already purchased private Starship missions around the Moon, paid for by Yusaku Maezawa and Jared Isaacman, will happen first. Both will certainly beat NASA’s planned landing on the Moon. I also expect both to beat that Orion manned fly-around in ’24-’25. And each will cost pennies compared to the entire SLS/Orion program, while actually making a profit that will be used to further development and more manned private flights.

NASA extends Boeing’s contract to produce more SLS rockets

NASA yesterday announced that it will pay Boeing $3.2 billion for two more SLS rockets.

NASA has finalized its contract with Boeing of Huntsville, Alabama, for approximately $3.2 billion to continue manufacturing core and upper stages for future Space Launch System (SLS) rockets for Artemis missions to the Moon and beyond.

Under the SLS Stages Production and Evolution Contract action, Boeing will produce SLS core stages for Artemis III and IV, procure critical and long-lead material for the core stages for Artemis V and VI, provide the exploration upper stages (EUS) for Artemis V and VI, as well as tooling and related support and engineering services.

All this really means is that NASA is going depend on SLS and Orion to fly its astronauts to and from the Moon, and because of that its pace of flight will be — at best — slow and long-drawn out. For example, this new order extends the contract out to 2028. It will thus leave plenty of time for SpaceX and other nations to get there first.

I predict that the private Starship missions paid for by Yusaku Maezawa and Jared Isaacman will both fly before these two new Artemis missions. You heard it here first.

Orion completes burn to send spacecraft back to Earth

NASA’s Orion capsule yesterday successfully fired its engines as it zipped past the Moon to send it on a trajectory back to Earth, with splashdown in the Pacific off the coast of California scheduled for December 11, 2022.

Not all was hunky-dory, however. Prior to the burn a power unit shut down unexpectedly.

A power unit on board the Orion spacecraft turned off four devices “responsible for downstream power” that connect to the Artemis 1 vehicle’s propulsion and heating subsystems, NASA officials wrote in a statement. But mission personnel swiftly put a fix in place and the mission is carrying on, the statement emphasized. “Teams confirmed the system was healthy and successfully repowered the downstream components,” agency officials wrote in the statement, released late on Sunday. “There was no interruption of power to any critical systems, and there were no adverse effects to Orion’s navigation or communication.”

Engineers think the shut down was related to a test performed in connection with an earlier incident.

Regardless, all now appears well for that December 11nd splashdown.

Orion fires engine, leaves lunar orbit

After firing its engines yesterday, NASA’s Orion spacecraft has left lunar orbit and begun a long looping route that will zip past the Moon and then head back to Earth.

The burn changed Orion’s velocity by about 454 feet per second and was performed using the Orion main engine on the European Service Module. The engine is an orbital maneuvering system engine modified for use on Orion and built by Aerojet Rocketdyne. The engine has the ability to provide 6,000 pounds of thrust. The proven engine flying on Artemis I flew on 19 space shuttle flights, beginning with STS-41G in October 1984 and ending with STS-112 in October 2002.

The burn is one of two maneuvers required ahead of Orion’s splashdown in the Pacific Ocean on Dec. 11. The second will occur on Monday, Dec. 5, when the spacecraft will fly 79.2 miles above the lunar surface and perform the return powered flyby burn, which will commit Orion on its course toward Earth.

The spacecraft will splashdown on December 11, 2022, if all goes right.

Orion enters retrograde lunar orbit

Engineers today successfully completed an engine burn that put Orion into the retrograde lunar orbit in which it will remain for the next week.

Due to the distance of the orbit, it will take Orion nearly a week to complete half an orbit around the Moon, where it will exit the orbit for the return journey home. About four days later, the spacecraft will harness the Moon’s gravitational force once again, combined with a precisely timed lunar flyby burn to slingshot Orion onto its return course to Earth ahead of splashdown in the Pacific Ocean on Sunday, Dec. 11.

As of now all systems seem to be working as intended.

Controllers lose contact with Orion for almost an hour

NASA engineers unexpectedly lost all contact with Orion for 47 minutes just after midnight last night.

NASA’s Mission Control Center at the agency’s Johnson Space Center in Houston unexpectedly lost data to and from the spacecraft at 12:09 a.m. CST for 47 minutes while reconfiguring the communication link between Orion and Deep Space Network overnight. The reconfiguration has been conducted successfully several times in the last few days, and the team is investigating the cause of the loss of signal. The team resolved the issue with a reconfiguration on the ground side.

At present the loss of signal caused no issues with the spacecraft. However, its cause has not yet been pinpointed.

Orion successfully enters its preliminary lunar orbit

NASA’s Orion capsule today successfully completed a 2.5 minute engine burn this morning to put it in its preliminary lunar orbit around the Moon.

At the time of the burn, Orion was 328 miles above the Moon, travelling at 5,023 mph. Shortly after the burn, Orion passed 81 miles above the Moon, travelling at 5,102 mph. At the time of the lunar flyby, Orion was more than 230,000 miles from Earth.

The outbound powered flyby burn is the first of two maneuvers required to enter the distant retrograde orbit around the Moon. The spacecraft will perform the distant retrograde orbit insertion burn Friday, Nov. 25, using the European Service Module. Orion will remain in this orbit for about a week to test spacecraft systems.

NASA has been bragging that when this orbit sends Orion 40,000 miles past the Moon, it will be the farthest a man-rated spacecraft has flown from Earth since Apollo. Though true, this fact is somewhat trivial. First, SpaceX could have easily put a Dragon capsule on its first Falcon Heavy launch, instead of a Tesla, and sent that capsule into interplanetary space beyond Mars. Second, Orion is not capable of taking any astronauts farther than lunar orbit. Thus, NASA’s achievement here is somewhat overblown. Orion is not an interplanetary spaceship. It remains nothing more than an overpriced, overweight, and over-designed ascent-descent manned capsule.
