CAPSTONE makes course correction, now on target for lunar orbital insertion on November 13th

1:39 pm

Engineers have successfully overcome the valve issue that had caused the CAPSTONE lunar probe to tumble, and have made a subsequent mid-course correction that has put the spacecraft on target for entering lunar orbit on November 13, 2022, as planned.

The CAPSTONE spacecraft successfully completed a trajectory correction maneuver on Thursday, Oct. 27, teeing up the spacecraft’s arrival to lunar orbit on Nov. 13.

CAPSTONE is no longer in safe mode following an issue in early September that caused the spacecraft to spin. The team identified the most likely cause as a valve-related issue in one of the spacecraft’s eight thrusters. The mission team will design future maneuvers to work around the affected valve, including the two remaining trajectory correction maneuvers scheduled before CAPSTONE’s arrival to orbit at the Moon.

Though it appears the CAPSTONE team has figured out how to deal with that malfuncting valve, it is unclear what the long-term ramifications of that valve will be. If it is still leaking it likely means the mission will be shortened because of loss of fuel, as well as the need to use more to compensate.

Boeing’s write-off due to Starliner delays goes up to nearly $900 million

8:45 am

Capitalism in space: In a SEC filing on October 26, 2022, Boeing revealed that it has been required to spend another $195 million to cover the additional costs due to the further delays in getting Starliner launched, bringing the company’s total expense now to $883 million.

Boeing acknowledged today that it is taking a further $195 million charge against earnings for the CST-100 Starliner commercial crew program. Developed through a fixed-price contract with NASA, Starliner has encoutered a number of delays and Boeing must cover those costs. Added to $688 million already taken, the company now is spending $883 million of its own money on the program.

Boeing’s original fixed-price contract was for $4.2 billion, and included the test flights as well as six operational flights to ISS. However, numerous problems caused repeated delays and the need to fly a second unmanned test flight. Originally planned for the spring of 2020, the first manned Starliner flight is now targeting February 2023, three years behind schedule. Due to that delay, SpaceX’s Dragon ended up getting new contracts that included many of the later operational flights that Boeing would have earned. Right now, even if the capsule begins flying in ’23, NASA’s already purchased six flights will cover its needs through around ’26.

After that, NASA will still need to buy manned flights, if only to get to the new commercial space stations being built, and Starliner will then be an option. This just means however that it will take Boeing a long time to recover its Starliner losses. And that assumes customers begin to line up to buy flights.

NASA buys 3 Orion capsules from Lockheed Martin for $2 billion

10:02 am

Nice work if you can get it! Earlier this week NASA awarded Lockheed Martin a new contract worth $1.99 billion to build three more Orion capsules for its Artemis program.

This order marks the second three missions under the agency’s Orion Production and Operations Contract (OPOC), an indefinite-delivery, indefinite-quantity (IDIQ) contract for up to 12 vehicles. A breakout of these orders includes:

  • 2019: NASA initiates OPOC IDIQ and orders three Orion spacecraft for Artemis missions III-V.
  • 2022: NASA orders three additional Orion spacecraft missions for Artemis VI-VIII for $1.99 billion.
  • In the future: NASA can order an additional six Orion missions.

Under OPOC, Lockheed Martin and NASA have reduced the costs on Orion by 50% per vehicle on Artemis III through Artemis V, compared to vehicles built during the design and development phase. The vehicles built for Artemis VI, VII and VIII will see an additional 30% cost reduction.

Lawdy me! They’ve reduced the price! Lockheed Martin is only charging NASA three-quarters of a billion dollars per capsule on this new contract (after NASA spent about $18 billion for the development of the first six capsules– that’s $3 billion each). And Lockheed Martin will only charge about a half billion per capsule for future capsules! My heart be still.

Meanwhile, SpaceX is designing, testing, building, and will likely launch its reusable Starship manned spacecraft, which could launch about 10 Orion capsules on each launch, for about $10 billion total. Once flying the expected cost per launch will likely be much less than $100 million, with SpaceX claiming it could be as low as $2 million. Even if you add the development cost for these launches, Starship will cost less than Orion by many magnitudes, on its first launch.

I wonder, which is the better bargain? NASA clearly can’t figure it out, and NASA has the smartest, most brilliant people in the universe working for it.

NASA approves use of American spacesuits for spacewalks after investigation

10:14 am

NASA this week gave approval to the resumption of spacewalks on ISS, using its American spacesuits, following its investigation into a March incident where one astronaut’s spacesuit became somewhat water-logged.

The agency has now completed a review of the incident, finding that it was not a leak caused by hardware issues. Instead, the water was condensation caused by high levels of astronaut exertion and the cooling setting on Maurer’s extravehicular mobility unit (EMU) spacesuit, NASA officials said.

Though NASA was somewhat vague about the solution, it appears it has simply told astronauts to adjust the cooling setting of their suits to prevent condensation within the suits.

These American suits are very complicated to use, and very expensive. The agency has contracted out for new suits from private companies, but it will be very instructive to see what SpaceX comes up with for the spacewalk suits it is making for the private commercial manned Polaris Dawn mission in the spring of 2023.

Watching return of ISS crew on Freedom

9:40 am

The SpaceX manned capsule Freedom has undocked from ISS, carrying three astronauts completing a six month mission, with a scheduled splashdown planned for 4:50 pm (Eastern) off the western coast of Florida.

I have embedded NASA’s live stream below, for those that wish to watch. Note that though NASA inserts itself into this event, once the spacecraft has left ISS everything — including all workers involved in splashdown operations — is solely under the supervision of SpaceX, with NASA’s participation only that of a customer, albeit a very powerful one. This is a capsule and splashdown designed, built, run, and most important, owned by a private American company, not the government.

NASA sets November 14th as next SLS launch date

9:38 am

NASA today announced that it will make its next attempt to launch its SLS rocket just past midnight on November 14, 2022.

NASA is targeting the next launch attempt of the Artemis I mission for Monday, Nov. 14 with liftoff of the Space Launch System (SLS) rocket carrying the Orion spacecraft planned during a 69-minute launch window that opens at 12:07 a.m. EST. Artemis I is an uncrewed flight test to launch SLS and send Orion around the Moon and back to Earth to thoroughly test its system before flights with astronauts.

This is the second launch opportunity in the November launch window, as shown in this graph [pdf]. It will result in a 26-day mission for the Orion capsule to and from lunar orbit, returning on December 9th.

Endurance docks at ISS

9:16 am

Like clockwork SpaceX’s Endurance capsule successfully docked at ISS yesterday, delivering four astronauts to the station for a six month mission.

The most interesting aspect of this launch and crew is Russian Anna Kikina.

Kikina is the first Russian to fly aboard a U.S. spacecraft in nearly 20 years. She and Rubio were launched under a new agreement between NASA and Roscosmos, the Russian space agency, that ensures at least one astronaut or cosmonaut is always aboard the space station even if a Crew Dragon or Soyuz is forced to depart early, taking its crew with it.

Without the seat-swap arrangement, a medical emergency or some other major problem could leave an all-Russian or all-NASA crew aboard without the expertise to operate the other nation’s systems.

The agreement had been stalled almost entirely by the former head of Roscosmos, Dmitry Rogozin. He is now gone however, sent by Putin to take over the fake occupation government in parts of the Ukraine. It appears his bellicose manner, that caused the loss of a billion dollars in launch contracts with OneWeb, was more than even Putin could handle.

With him gone, the new head of Roscosmos, Yuri Borisov, quickly finalized this astronaut barter deal. He has also publicly acted to try to ease tensions between the U.S. and Russian space agencies.

Important Roscosmos official endorses continuing cooperation with US in space

12:28 pm

In a clear sign of the distinct change in atmosphere since the removal of Dmitry Rogozin as head of Roscosmos, the executive director of human space flight programs at Roscosmos, Sergei Krikalev, yesterday endorsed the longstanding cooperation between the U.S. and Russia in space.

Krikalev’s comments came after the launch yesterday of Endurance with one Russian astronaut as part of its four-person crew.

At a briefing after the Oct. 5 launch of the Crew-5 mission from the Kennedy Space Center, Sergei Krikalev, executive director of human space flight programs at Roscosmos, emphasized long-running cooperation between the United States and Russia in civil space, cooperation that has been strained since Russia’s invasion of Ukraine in February.

“We just continue what we started many years ago in 1975 when the Apollo-Soyuz crew worked together, and now we continue our cooperation,” he said after mentioning a “new phase of cooperation” with the exchange of seats between NASA and Roscosmos.

To understand the importance of Krikalev’s comments, you must also understand the context. First, Krikalev is a very significant figure in the history of Russia. He was called the last Soviet citizen, having been stranded on Mir an extra few months when the Soviet Union fell in 1991. Then he was the first Russian to fly on the shuttle, followed later by being on the first mission to ISS, when it was only two modules.

Since his retirement as an active astronaut, he has become the man in charge of Russia’s manned program, where he clashed with Rogozin several times over policy. His opposition to Rogozin almost certainly was a factor in Rogozin’s removal.

Krikalev’s endorsement of continuing the U.S-Russian partnership only cements that partnership, especially because Krikalev himself is a dyed-in-the-wool communist at heart. At least, he said so emphatically when I interviewed him at length in 2003 for Leaving Earth. I doubt his mind has changed in this matter, though his relentless honesty as an engineer has probably shaken his dedication to that failed ideology in subsequent years.

Nonetheless, his standing in Russia gives any statement he makes great weight. Expect more efforts by the Russians to ease tensions with the U.S., though their chances of success will be limited as long as Russia is continuing its unprovoked invasion of the Ukraine.

SpaceX successfully launches astronauts to ISS

9:40 am

Capitalism in space: SpaceX this morning successfully launched two NASA astronauts, one Japanese astronaut, and one Russian astronaut into orbit for a mission to ISS, with the docking scheduled for tomorrow.

The capsule, Endurance, is making its second flight. This was SpaceX’s eighth manned launch. The first stage, making its first fight, landed successfully on the drone ship in the Atlantic. This was the first new first stage launched since May 2022, and only the second this year. All other launches in 2022 were completed using SpaceX’s existing fleet of boosters. The company also continues to hold to the pattern of last year for maintaining that fleet, by adding two new boosters each year.

That this achievement is now becoming as routine as SpaceX’s unmanned launches proves the company’s success. And SpaceX did it in less than a decade, something NASA with its government-built shuttle was never able to accomplish.

The leaders in the 2022 launch race:

44 SpaceX
41 China
12 Russia
7 Rocket Lab
7 ULA

American private enterprise now leads China 63 to 41 in the national rankings, and the entire world combined 63 to 61.

Spinlaunch completes 10th test launch, this time for outside customers

9:15 am

Spinlaunch prototype launcher

Capitalism in space: Spinlaunch on September 27, 2022 successfully completed the 10th test launch of its radical spin launch centrifuge, this time accelerating test components to approximately 35k feet for other potential customers, including NASA.

Flight Test 10, which had a similar flight trajectory as previous campaigns, was witnessed by more than 150 partners, government officials, and industry advocates. It was SpinLaunch’s tenth flight test in just under eleven months since the Suborbital Mass Accelerator came online in late 2021.

…Four partner payloads, as well as two instrumentation payloads, were flown on the Suborbital Accelerator Flight Test Vehicle. For partners, the flight test provided critical data on the launch environment and payload integration process.

As part of the pre-flight qualification process, SpinLaunch accelerated payloads up to 10,000G in SpinLaunch’s 12-meter Lab Accelerator at its Long Beach headquarters. Payloads were inspected post-spin and subsequently integrated into the Flight Test Vehicle in preparation for Flight Test 10.

It remains to be seen whether this technology will work for launches to orbit. Even if it does, because of the stress produced during spin up this launch technique will really only work for bulk payloads to orbit, such as water and oxygen. If it works however it could reduce launch costs for these items tremendously.

SpaceX and Jared Isaacman offer private mission to NASA to raise Hubble’s orbit

9:44 am

Capitalism in space: In a press release issued yesterday, NASA revealed that it has signed an unfunded agreement with SpaceX and Jared Isaacman’s Polaris program (which has purchased a series of manned missions on Dragon) to study the possibility of sending one of those private manned missions to the Hubble Space Telescope to raise its orbit.

SpaceX – in partnership with the Polaris Program – proposed this study to better understand the technical challenges associated with servicing missions. This study is non-exclusive, and other companies may propose similar studies with different rockets or spacecraft as their model.

Teams expect the study to take up to six months, collecting technical data from both Hubble and the SpaceX Dragon spacecraft. This data will help determine whether it would be possible to safely rendezvous, dock, and move the telescope into a more stable orbit.

In my book describing the history of the people who created Hubble, The Universe in a Mirror, I repeatedly noted how throughout its history people have tried to kill it, first in the design phase, then in the budget, then during construction, then after it was launched and the mirror was found to be ground incorrectly, and then after the Columbia accident when NASA management tried to cancel its last shuttle servicing mission.

Every attempt failed. As I have noted in that book and many times since its publication, Hubble is a telescope that will not die. NASA has for years intended to launch a mission to de-orbit it when its orbit had decayed enough that it was unstable. I’ve always said that when that time came, someone would propose and push for a mission to instead raise that orbit.

That prediction is now coming true. Though no robot arm exists yet for Dragon to use to grab Hubble in any rendezvous attempt, creating one is hardly difficult. At that point raising the telescope’s orbit becomes relatively trivial.

Whether such a mission could do more, such as replace Hubble’s ailing gyroscopes, is unknown. It would be foolish however not to review that possibility as well.

SpaceX to upgrade 2nd Kennedy launchpad for manned launches

10:13 am

In order to create some increased redundancy, SpaceX and NASA have agreed to upgrade the company’s second launchpad at Cape Canaveral, LC-40, so that both it and pad LC-39A can launch manned Dragon capsules.

This plan grew out of concern by NASA that the new Starship orbital launchpad was too close to LC-39A, and could possibly damage it during a launch. Should that happen, and no back-up launchpad was available, the agency would have no way to get astronauts up to ISS, since Boeing’s Starliner is not yet operational. Because of that concern, NASA made it clear that no Starship launches could occur in Florida until this issue was resolved.

The solution? Make LC-40 a manned launchpad too.

Nothing is known about the nature of the modifications that LC-40 will require. But more likely than not, NASA will require SpaceX to develop something similar to Pad 39A’s facilities. That would involve building a new crew access tower, crew access arm, escape system (39A uses baskets and ziplines), and an on-site bunker for astronauts.

It is also likely that no Starship launches at Kennedy will occur until this work is done and a manned launch from LC-40 takes place. Though this could delay Starship somewhat, I expect not significantly. Before SpaceX is ready to launch operationally in Florida, it still has to do a lot of testing and development of Starship/Superheavy in Boca Chica, work that could take several years. I also suspect that it will get the launchpad work done relatively quickly, especially if NASA agrees to pay for it.

NASA and ESA sign simple lunar exploration agreement

9:57 am

In what appears to be an attempt by both to maintain their working relationship, even though several major European nations have not yet signed the Artemis Accords, last week NASA and ESA signed a simple agreement reaffirming their desire to work together in exploring the Moon.

Neither ESA nor NASA published the agreement, which in a photograph appeared to be little more than one page. In a Sept. 23 statement, NASA described the agreement as a “non-binding joint statement” about current and prospective future cooperation in Artemis.

Of ESA’s members, only France, Italy, Luxembourg, Poland, and the United Kingdom have signed the Artemis Accords. Thus, ESA and NASA face a conundrum. According to the accords and the NASA policy established by the Trump administration and supposedly continued under Biden, only signatories can participate in the Artemis program. Yet, most of the members of ESA have not signed, and ESA has no authority to make them do so. ESA however is building the service module for the Orion capsule — as well as other major components of Artemis — which NASA must have.

I suspect this short one page agreement is the Biden administration’s under-handed admission that — when it comes to Europe — the Artemis Accords will no longer be required.

NASA managers decide finally to roll SLS back to assembly building

9:01 am

NASA managers this morning finally gave up on launching their SLS rocket in an early October launch window and scheduled rolling back the rocket to the assembly building tonight.

NASA will roll the Artemis I Space Launch System rocket and Orion spacecraft back to the Vehicle Assembly Building on Monday, Sept. 26. First motion is targeted for 11 p.m. EDT.

Managers met Monday morning and made the decision based on the latest weather predictions associated with Hurricane Ian, after additional data gathered overnight did not show improving expected conditions for the Kennedy Space Center area. The decision allows time for employees to address the needs of their families and protect the integrated rocket and spacecraft system. The time of first motion also is based on the best predicted conditions for rollback to meet weather criteria for the move.

Based on this graph [pdf] provided by NASA earlier this year, the next launch window is from October 17 to October 31, followed by another from November 12 to November 27. It is unclear whether they can meet that first window, even if all engineers do is check and recharge the flight termination system batteries.

The question of the rocket’s two solid-fueled boosters however looms. Both are now one year past NASA’s use-by date, and it appears somewhat unknown what the risks are using them. Replacing them however will entail a significant delay, from three to six months.

As I said this weekend, NASA managers face no good choice, because of the impractical and inefficient design of this rocket.

NASA managers might forego SLS rollback and aim for Oct 2nd launch

9:20 am

Based on the present hurricane track, NASA managers are considering the possibility of leaving SLS on the launchpad so that they can go for a launch on October 2, 2022.

NASA managers will meet this evening to evaluate whether to roll back or remain at the launch pad to preserve an opportunity for a launch attempt on Oct. 2. The exact time of a potential rollback will depend on future weather predictions throughout the day and could occur Monday or very early Tuesday morning.

If they stay on the launchpad, it means the flight termination system is questionable at launch. If the rocket goes out of control during its first test launch — a not-unreasonable possibility for a new rocket — there is a chance the range officer will not be able to destroy it.

If they roll back to the assembly building, it means the rocket’s two solid strap-on boosters will either have to be replaced, delaying the launch months more, or the rocket will launch with two boosters that are questionable.

Every choice they face is a bad one, simply because this rocket is really not well designed for practical use.

Range gives NASA waiver to launch SLS on September 27th, despite a questionable flight termination system

1:01 pm

In a briefing today, NASA officials confirmed that they are proceeding with their September 27, 2022 first launch of the SLS rocket, having obtained a waiver from the Space Force’s range office on testing the batteries for the flight termination system that would destroy the rocket should it begin flying out of control.

During a Sept. 23 teleconference, NASA announced an extension for the flight termination system battery certification, which expired after 25 days on Sept. 6. Now the Space Force’s Eastern Range has granted a waiver to allow the rocket to launch as late as Oct. 2 before needing to be returned to the Vehicle Assembly building to recertify the batteries.

The flight termination system is only used in the event the rocket veers off course during a launch anomaly.

Note that the 25 day use-by limit was actually an extension itself, as these batteries had been previously required testing every 20 days. Now the range is willing to let them go for as long about 50 days without testing, a two and half times increase.

If the rules before — based on engineering — said the batteries were not reliable after 20 days, why are those batteries now considered reliable up to 50 days? What facts or data does NASA or the Space Force have to allow this waiver? And if they have no data, it seems almost criminal to allow the go-ahead of this launch of a giant untested rocket on its first lift-off. Should something go seriously wrong — which is not that unlikely — and the flight termination system fails to work, we could see a very big rocket careening out-of-control into populated areas.

We all hope SLS launches with no problem on September 27th. We now have a really serious reason for that desire.

Regardless, the launch is now scheduled for a 70-minute launch window that opens at 11:37 am (Eastern) on September 27th, with a back-up launch window on October 2nd of 102 minutes beginning at 2:52 pm (Eastern).

Meanwhile, a developing tropical storm could put a kabosh on all these plans, forcing NASA to roll SLS back to the assembly building anyway. NASA managers plan to meet again before launch to make a decision.

Watching DART impact asteroid on September 26, 2022

9:35 am

A NASA planetary probe, dubbed DART, is on course for a planned impact of the asteroid Dimorphos this coming Monday, September 26, 2022, at 4:14 PM (Pacific).

DART was launched from Vandenberg Space Force Base, CA on November 23, 2021 PST (November 24 EST) headed to the asteroid Didymos and its tiny moon Dimorphos 7 million miles away. The plan is for DART to ram itself into Dimorphos while scientists on Earth measure whether its orbit around Didymos changes.

Dimorphos is about 525 feet in diameter, while Didymos is much larger, about a half mile in width. The goal is to see if this method can be used in the future to adjust an asteroid’s orbit enough to shift it away from hitting the Earth.

The impact will be observed by a camera on DART, as well as an Italian cubesat dubbed LICIACube.

NASA TV will be live streaming the event, and I will embed that live stream here when it goes live. Once DART gets close, its camera will record the asteroid’s approach through impact.

SLS fueling test completed

9:38 pm

NASA engineers today successfully completed the tanking test of the agency’s SLS rocket, completing all objectives after successfully dealing with a hydrogen fuel leak at the beginning of fueling.

The four main objectives for the demonstration included assessing the repair to address the hydrogen leak identified on the previous launch attempt, loading propellants into the rocket’s tanks using new procedures, conducting the kick-start bleed, and performing a pre-pressurization test. The new cryogenic loading procedures and ground automation were designed to transition temperature and pressures slowly during tanking to reduce the likelihood of leaks that could be caused by rapid changes in temperature or pressure. After encountering the leak early in the operation, teams further reduced loading pressures to troubleshoot the issue and proceed with the demonstration test. The pre-pressurization test enabled engineers to calibrate the settings used for conditioning the engines during the terminal count and validate timelines before launch day to reduce schedule risk during the countdown on launch day.

Teams will evaluate the data from the test, along with weather and other factors, before confirming readiness to proceed into the next launch opportunity. The rocket remains in a safe configuration as teams assess next steps. [emphasis mine]

The highlighted words are key. NASA has proposed a September 27, 2022 launch date. For that launch to occur, the rocket must remain on the launchpad, where it is impossible to check the batteries for operating the flight termination system used by the military range office to destroy the rocket should it go wildly out of control during launch. To check the batteries they need to roll it back to the assembly building, and one week is simply not enough time.

The vagueness of the highlighted language suggests that NASA has not yet gotten a waiver from the range for that date. Nor should it. Those batteries normally have a 20-day limit. On September 27th they will been unchecked for about 42 days, well past their use-by date.

This will be the first test launch of this rocket. Such first launches very frequently go wrong, and if SLS goes wrong, it would go wrong in a very big way, considering the size of the rocket. To do such a risky launch with a questionable flight termination system would not simply be improper it would be downright criminal.

Hydrogen leak detected during today’s SLS tank test

9:08 am

Though engineers have apparently overcome the issue so that today’s tank test of NASA’s SLS rocket can continue, a hydrogen leak was nonetheless detected during fueling.

The fueling tank test is not yet complete.

At this moment I cannot imagine the military’s range office will allow NASA to launch on September 27th, as the agency has requested. To do so will require the range to ignore the possibility that the flight termination is inoperable, as its batteries are past their use-by date by almost a month. Combined with these ongoing leak issues, it would be irresponsible to do otherwise.

NASA releases new overall objectives for exploration of solar system

11:28 am

NASA today released a new roadmap for its goal of exploring the Moon, Mars, and the rest of the solar system, with the goal of providing an overarching strategy for everything it hopes to accomplish.

The resulting revised 63 final objectives reflect a matured strategy for NASA and its partners to develop a blueprint for sustained human presence and exploration throughout the solar system. They cover four broad areas: science; transportation and habitation; lunar and Martian infrastructure; and operations. The agency also added a set of recurring tenets to address common themes across objectives.

You can read the full document here [pdf].

The most astonishing thing about this roadmap is its utter lack of any mention of race or gender, especially when one considers how obsessed the Biden administration and its minions in federal bureaucracy have been over such things. The goals are entirely focused on exactly what they should be focused on, exploration and research, with the goal of partnering with as many private and governmental entities as possible to get it done in the most efficient way.
