ISS government partners give okay to Axiom’s first commercial crew to station

9:26 am

Capitalism in space: NASA announced yesterday that it as well as the other international partners for ISS have approved the crew and passengers who will fly on Axiom’s first commercial flight to the station, presently scheduled for launch on March 30, 2022, flying in SpaceX’s Endeavour capsule.

Axiom Space astronauts Michael López-Alegría, Larry Connor, Mark Pathy, and Eytan Stibbe are prime crew members of the Ax-1 mission. López-Alegría, who was born in Spain, raised in California, and a former NASA astronaut, will serve as the mission commander. Connor, of Dayton, Ohio, will serve as pilot. Pathy, from Canada, and Stibbe, from Israel, will be mission specialists. The quartet is scheduled to spend eight days aboard the orbiting laboratory conducting science, education, and commercial activities before their return to Earth.

Because the four will be staying at this government station, they must work with NASA, which appears to be requiring them to do some research while on board. Those experiments are still “under review” though Axiom has already revealed a suite of microgravity experiments the crew will perform.

SpaceX’s failure to win space station NASA contract reveals where the company is weak

12:11 pm

Jeff Foust of Space News today has a detailed article detailing NASA’s decision-making process that led to its awarding Blue Origin, Northrop Grummann, and Nanoracks development contracts for their proposed commercial and private space station.

The article not only describes NASA’s analysis of each winning bid, it also describes the analysis of some of the eight bids that lost. Most interesting were the strengths and weaknesses NASA saw from SpaceX’s bid.

The company won strengths based on its technical maturity linked to HLS proposal (the Starship lunar lander) and a “strong approach” to communications that appeared to be associated with SpaceX’s Starlink constellation. However, NASA assessed several weaknesses because of a lack of details about its concept, including how it will accommodate payloads and scale up an environmental control system for long-duration missions. [emphasis mine]

While SpaceX so far has proven itself to be a brilliant rocket and engineering company — achieving things that everyone else said couldn’t be done and doing so so quickly it takes your breath away — the company has so far appeared to have little understanding or knowledge about the complexities of building an interplanetary manned vessel. This NASA analysis, as noted by the highlighted phrases in the quote above, underlines that impression.

None of this precludes SpaceX from gaining that knowledge and applying it to the engineering of future Starship designs. This information however shows that the company still lacks this knowledge. It apparently has still not tackled the job of designing the insides of Starship, only its rocketry for getting into orbit.

NASA’s second SLS mobile launch tower now behind schedule

10:47 am

Par for the course: According to one member of NASA’s safety panel, the contractor building NASA’s second SLS launch tower, is having performance problems and is already behind schedule.

On Thursday, during a meeting of NASA’s Aerospace Safety Advisory Panel, one of its members provided an update on Mobile Launcher-2. George Nield, an engineer and scientist who previously led commercial space transportation for the Federal Aviation Administration, said the 90-percent design, review, and fabrication drawings for the large structure are behind schedule. These are the engineering drawings that should closely represent the final design and inform a construction schedule and logistics plan.

“Mobile Launcher-2 has encountered some challenges,” Nield said. “The selected contractor, Bechtel, has experienced some performance issues associated with underestimating the complexity of the project and some supplier related issues, as well as COVID.”

Note that NASA spent about $1 billion on the first tower, to be used only three times, at most. Its contract with Bechtel says the second tower will cost $383 million, but no one expects that number to be met.

Assuming Bechtel does not go over budget (hah!), NASA will have spent $1.4 billion on SLS’s launch towers, one of which will be used two or three times and then abandoned. That’s three times the cost of what SpaceX spent developing Falcon Heavy, and about a third the total development cost of Starship/Superheavy, including its planned launchpads in both Boca Chica and Florida.

SpaceX aiming to launch 52 times in 2022

9:31 am

According to NASA officials, SpaceX is hoping to complete as many as 52 launches in 2022, a pace of one launch per week.

The impressive figure was given during a virtual meeting of NASA’s Aerospace Safety Advisory Panel, or ASAP, which gives guidance to the space agency on how to maintain safety within its biggest programs. “NASA and SpaceX will have to be watchful during 2022 that they’re not victims of their success,” Sandy Magnus, a former NASA astronaut and member of the panel, said during the meeting. “There’s an ambitious 52-launch manifest for SpaceX over the course of the year. And that’s an incredible pace.”

Based on other sources, I had previously estimated a SpaceX manifest for ’22 to be 40 launches. That this new higher number comes from NASA’s corrupt safety panel, and was touted as a reason to raise questions about SpaceX, makes me suspicious of it.

Still, a launch pace by SpaceX of one launch per week is wholly possible. For one thing, the company needs to get a lot of Starlink satellites into orbit as quickly as possible. With its development of Starship blocked by government interference, it might have decided to up the pace of launches using Falcon 9.

Furthermore, because most of the rocket is reused, SpaceX has a far greater launch capacity. For every Falcon 9 it builds it gets ten or more launches from its first stage. This means SpaceX does not have to build as much to maintain a high launch pace.

As for the safety panel’s fears about such a pace, who cares? That safety panel has been consistently wrong about everything it has said about SpaceX and commercial space now for almost a decade. It is very likely wrong now. In a more rational world, NASA would have shut it down two years ago for doing such a bad job. Sadly, we no longer live in a rational world.

Webb successfully inserted in final orbital position at the Sun-Earth Lagrange point

3:01 pm

The James Webb Space Telescope today successfully completed a five minute firing of its engines to place it at the Sun-Earth Lagrange point dubbed L2.

Webb’s orbit will allow it a wide view of the cosmos at any given moment, as well as the opportunity for its telescope optics and scientific instruments to get cold enough to function and perform optimal science. Webb has used as little propellant as possible for course corrections while it travels out to the realm of L2, to leave as much remaining propellant as possible for Webb’s ordinary operations over its lifetime: station-keeping (small adjustments to keep Webb in its desired orbit) and momentum unloading (to counteract the effects of solar radiation pressure on the huge sunshield).

Engineers will spend the next three months aligning the segments of Webb’s large primary and secondary mirrors, while they wait for the telescope to cool down to the ambient very cold temperatures required for it to detect the tiny infrared heat emissions from very faint very very very distant objects.

NASA: No further Artemis Moon landings for at least two years after first in 2025

11:53 am

The tortoise appears to be dying: NASA today announced that there will be a two-plus year pause of Artemis missions to the lunar surface after it completes its hoped-for first manned Moon landing in 2025.

In presentations at a two-day meeting of the NASA Advisory Council’s Human Exploration and Operations Committee Jan. 18 and 19, agency officials said the Artemis 4 mission, the first after the Artemis 3 mission lands astronauts on the moon, will not attempt a landing itself.

Instead, Artemis 4 will be devoted to assembly of the lunar Gateway. The mission will deliver the I-Hab habitat module, developed by the European Space Agency and the Japanese space agency JAXA, to the Gateway. It will be docked with the first Gateway elements, the Power and Propulsion Element and Habitation and Logistics Outpost, which will launch together on a Falcon Heavy in late 2024 and spend a year spiraling out to the near-rectilinear halo orbit around the moon.

Essentially, the Biden administration appears to be switching back to NASA’s original plans, to require use of the Lunar Gateway station for any future lunar exploration, thus delaying that exploration considerably. Do not expect any of this schedule to take place as promised. The 2025 lunar landing will be delayed, as will all subsequent SLS launches for Artemis. The rocket is simply too complicated and cumbersome to even maintain one launch per year, while inserting Gateway into the mix only slows down lunar exploration even more.

NASA officials also revealed that they are limiting their lunar landing Starship contract with SpaceX to only that single planned ’25 Moon mission. For future manned missions to the Moon the agency will request new bids from the entire industry.

NASA’s Human Landing System (HLS) Option A award to SpaceX last year covers only development of a lander and a single crewed flight on Artemis 3. NASA will acquire future landings through a separate effort, called Lunar Exploration Transportation Services (LETS). The goal of LETS is to select one, and possibly more, companies to provide “sustainable” landing services.

The timing of LETS — a draft request for proposals is scheduled for release this spring — means there will be a gap of a couple years before the first landing service acquired through that program would be ready. “It’ll be about two years from the Option A award to the LETS award before we’ll have this sustainable lander,” Kirasich said. “It’s a different lander with more aggressive requirements than Option A.”

It appears that Jeff Bezos’ political lobbying efforts have paid off, and that NASA is now reopening bidding so that his consortium, led by Blue Origin, can once again compete for that lunar lander contract. Whether the Bezos’ team will be able to propose anything comparable to Starship is however very questionable.

None of this really hurts SpaceX. Its contract with NASA helps them develop a Starship lunar lander. Then, while NASA twiddles its thumbs building Gateway, it will be free to fly its own lunar missions, selling tickets on the open market. I suspect that — should NASA succeed in landing humans in ’25 — the next American manned landing on the Moon will be a bunch of SpaceX customers, not that second Artemis mission sometime in the late 2020s.

SpaceX of course will also be able to bid on that second lunar landing competition. And it will be hard for NASA not to award Starship a further contract, even if others are competing against it. Starship will be operational. The others will merely be proposed.

Flight dates for SpaceX’s next two manned flights to ISS revised

9:24 am

Capitalism in space: A NASA official yesterday announced that the flight dates for SpaceX’s next two manned flights have been firmed up, with the private commercial Axiom AX-1 flight delayed from February 21st to March 31st, followed two weeks later by NASA’s own manned mission on April 15th.

Axiom has also noted that this commercial flight, piloted by a former NASA astronaut and carrying three passengers, will be its only commercial manned flight in ’22.

…Commanded by former NASA astronaut Michael López-Alegría, Ax-1 will only carry private citizens. Each paying $55 million for the privilege, the mission’s three customers are Larry Connor, Mark Pathy, and Eytan Stibbe – all businessmen who’ve respectively amassed multmillion-dollar fortunes in real estate; entertainment and shipping; and military equipment and venture capitalism.

Their Dragon spacecraft will be Resilience, making its third flight.

Axiom’s next private commercial flight has now been delayed until ’23.

Boeing and NASA still aiming for a May launch of unmanned Starliner test demo

7:58 pm

Capitalism in space: Boeing and NASA are still targeting a May launch of Starliner’s unmanned test demo flight to ISS, delayed since August because of a valve issue in the service module.

Though they think they have identified and fixed that sticky valve problem, they have also decided to replace the service module for the demo flight, using the module originally planned for the first manned flight that will follow.

Update on SLS: Still aiming for very unlikely March launch

9:20 am

A detailed update on the work being done by NASA and Boeing engineers to prepare SLS for its first unmanned test launch suggests that though a March launch is still the target, it is likely to be delayed.

The update at the link is very thorough, and outlines a large number of tests that need to be done to get this very cumbersome and complicated rocket ready for launch. They are just about done with the prep work for the core stage, and are now shifting to final testing of the upper stage, followed by some countdown sequence testing and a test of the flight termination system. In addition there are a number of other tests they wish to perform, all of which will take time.

Once these are done they will be ready to roll the rocket out to the launchpad for a final dress rehearsal countdown — dubbed the Wet Dress Rehearsal (WDR), now scheduled for mid- to late-February.

NASA will not set a launch date until after the WDR is completed and they can factor in any additional tasks with already-known work. “We’ve continually said that until we get through WDR we won’t set a launch date, so us getting out in mid-February for WDR allows them to look at March and April as opportunities,” Lanham said.

“I really can’t put my finger on it again until we come back from WDR and see if we have any issues there that we’ve got to go correct.” After the WDR test, the vehicle and Mobile Launcher will be rolled back to the VAB for final pre-launch maintenance and servicing.

Some have said the earliest realistic launch date is May, with the mid-summer more likely. We shall have to wait and see.

House Democrats attempt end-around of filibuster to pass election law using NASA bill

9:09 am

A bill initially written to give authorization to NASA lease its property to others and and passed by the Senate has been stripped entirely of that language by House Democrats and replaced with their proposal to federalize elections nationwide.

H.R. 5746 was introduced in October by Rep. Don Beyer (D-Va.), chair of the House Science Committee’s space subcommittee. The bill extended NASA’s authorization to enter into what are known as enhanced use leases, or EULs, of agency property to companies, government agencies, or educational institutions, for 10 years. The House passed the bill by a voice vote Dec. 8.

The Senate amended the bill, extending the EUL authorization by only three months instead of 10 years, and passed it by unanimous consent, sending it back to the House.

The Democratic leadership of the House, in an unusual move, then took the Senate-amended bill and stripped out the NASA provisions, replacing it with the text of two voting rights bills and now called the “Freedom to Vote: John R. Lewis Act.” They did so because H.R. 5746 had already passed the House and Senate, so the amended version could go directly to the Senate floor without the threat of a filibuster from Senate Republicans, who oppose the voting rights legislation. [emphasis mine]

The level of corruption exhibited by this Democratic Party action is beyond words. The Senate approved one bill. The House Democrats have now turned it into another bill that the Senate did not vote on initially.

In the past, such a corrupt action by the House would never have been attempted because the House would have known that the entire Senate would have rejected this tactic immediately as an insult to its legislative rights. Today however the Democrats care nothing for legalities or law or legislative rights. All they care about is power, and they are willing to do anything to get it. You can expect for certain that all but two Democrats in the Senate will support this crooked action.

That vote’s passage however rests with those two Democrats. Since this tactic is a direct attack on the filibuster, and if successful would forever make it null, we must wonder if Senators Kysten Sinema (D-Arizona) and Joe Manchin (D-West Virginia) will vote against it. If they don’t, their high-minded claims that they will not end the filibuster rule will be proven to be empty words.

NASA’s safety panel claims management expertise in ’21 annual report, demanding that NASA run Artemis using a “top-down” approach

10:17 am

NASA’s safety panel today issued its 2021 annual report, and rather than review issues of safety in the operations of the agency’s various manned programs, the panel focused on proposing a redesign of the management structure of NASA manned programs, demanding that NASA run Artemis using a “top-down” approach, taking power and control away from private commercial space and putting it in the hands of NASA’s bureaucracy. From the press release:

Specifically, the report recommends that NASA should develop a strategic vision for the future of space exploration and operations; establish and provide leadership through a “board of directors” that includes agency center directors and other key officials, with the emphasis on providing benefit to the agency’s mission as a cohesive whole; and manage Artemis as an integrated program with top-down alignment. The panel also reiterated a recommendation from its 2020 report that Congress designate a lead federal agency for civil space traffic management.

This summary captures nicely the substance of the entire report [pdf]. Rather than review the specific safety issues in each of NASA’s manned programs — the panel’s actual job — the panel decided it would look at how Congress, the White House, and NASA’s leadership have organized the management of its manned program, and tell them all how to do things.

None of this is the safety panel’s business. Such recommendations should come from Congress or the White House, or from a specific panel created by those elected officials or NASA’s top management, tasked with the specific job.

The panel meanwhile ignored its real job, to review the engineering of NASA’s manned program and spot areas where such work might need to be revised or fixed. While the panel spent its time in 2020 putting together this inappropriate report, it apparently missed entirely the valve problem in Boeing’s Starliner capsule that has caused an additional year delay in its launch.

This panel continues to demonstrate its corrupt and power-hungry attitude about how the U.S. should explore space. For years it did whatever it could to stymie NASA’s efforts to transfer ownership to the private sector, putting up false barriers to the launch of SpaceX’s manned Dragon capsule that made no sense and were really designed to keep all control within the government bureaucracy.

Now this panel has decided its job is no longer to review the specific technical and engineering issues that could cause a manned spacecraft failure, such as with Boeing’s Starliner. Instead it now believes it should be the designer of NASA’s entire management.

It is long past time that this panel is shut down. It isn’t doing its actual job, and is instead interfering with everyone else’s.

Engineers replace engine controller on SLS core; launch to be delayed

9:12 am

Engineers have successfully replaced the failed engine controller on the core stage of NASA’s SLS rocket.

Last week engineers and technicians successfully removed and replaced an engine controller from one of four RS-25 engines after the team identified an issue during a power-up test of the rocket’s core stage. Engineers are now performing standard engine controller diagnostic tests and check-outs, including controller power-up and flight software load. Subsequently, the team will work to complete all remaining SLS pre-flight diagnostic tests and hardware closeouts in advance of a mid-February rollout for a wet dress rehearsal in late February. NASA will set a target launch date after a successful wet dress rehearsal test.

The official schedule still lists the launch for February, but NASA has already admitted this is now impossible. Once they complete the wet dress rehearsal on the launchpad they will have to roll the rocket back into the Vehicle Assembly Building to do further tests. While it remains possible for NASA to meet an April launch window, more likely the agency will push back to windows during the summer.

Thus, the race between SLS and Starship for completing the first orbital flight remains neck-and-neck. Starship could launch this spring, but it faces an uncertain schedule determined not by SpaceX but by the bureaucracy in the federal government, which is reviewing the FAA’s environment reassessment for the Boca Chica launch site and really has no requirement to meet any schedule at all. The FAA says it plans to approve the reassessment by the end of February, but that is simply made up deadline. It could revise it at will at any time.

NASA meanwhile is still pushing to launch SLS in April, but this launch date is entirely unrealistic. Expect NASA to announce a new target date sometime in the summer in the coming weeks.

Webb deploys heat radiator

8:57 am

Engineers today successfully deployed the heat radiator on the James Webb Space Telescope, allowing for unfolding of its 21-foot-diameter primary mirror over the next two days, the final step in the telescope’s deployment.

At about 8:48 a.m. EST, a specialized radiator assembly necessary for Webb’s science instruments to reach their required low and stable operating temperatures deployed successfully. The Aft Deployable Instrument Radiator, or ADIR, is a large, rectangular, 4 by 8-foot panel, consisting of high-purity aluminum subpanels covered in painted honeycomb cells to create an ultra-black surface. The ADIR, which swings away from the backside of the telescope like a trap door on hinges, is connected to the instruments via flexible straps made of high-purity aluminum foil. The radiator draws heat out of the instruments and dumps it overboard to the extreme cold background of deep space.

The whole operation took fifteen minutes.

If all goes well, by Saturday night (January 8th) engineers and scientists will have in their hands the world’s largest infrared telescope, and it will be operating in space. Actual scientific observations however will not begin immediately. It will still take several weeks for the telescope to cool down to the very cold temperatures it needs to see faint infrared objects, and then about five more months of additional testing to precisely align the mirrors while figuring out how the telescope itself operates in space.

We should expect the first raw and unaligned infrared images in about a month, with the first official observations released sometime in the very early summer.

NASA finally makes available to the aerospace industry its new flight termination software

2:59 pm

After what appears to be about a year and a half delay, NASA finally today made available its new flight termination software so that the aerospace industry can now test it.

“This is a major milestone that enables Rocket Lab and other U.S. launch companies to integrate the software now with their launch vehicle’s hardware and run performance simulations,” said David L. Pierce, Wallops Flight Facility director. “This is a key achievement toward enabling Rocket Lab launches from Wallops, in parallel with the NASA teams’ final safety certification steps, which are currently underway. Rocket Lab’s use of the NASA software will enable a high degree of confidence moving forward toward launch.”

Rocket Lab had hoped to launch from Wallops more than a year ago, but was blocked by NASA because the agency was apparently behind schedule in preparing this software. Now that it is finally available for testing, expect Rocket Lab to move swiftly, with a likely Wallops launch within months.

Webb engineers successfully deploy the telescope’s secondary mirror

2:50 pm

Engineers today confirmed that the secondary mirror for the James Webb Space Telescope has successfully deployed, its tripod structure unfolding and locking into place.

In addition the cover protecting the Mid-Infrared Instrument (MIRI) was successfully unlocked. The instrument’s science team did not open the cover yet because the telescope hasn’t yet cooled enough, its sun shield only in place for a day or so.

Webb: Sun shield deployment completed

3:32 pm

Engineers today successfully completed the full deployment of the sun shield of the James Webb Space Telescope.

The unfolding and tensioning of the sunshield involved 139 of Webb’s 178 release mechanisms, 70 hinge assemblies, eight deployment motors, roughly 400 pulleys, and 90 individual cables totaling roughly one quarter of a mile in length. The team also paused deployment operations for a day to work on optimizing Webb’s power systems and tensioning motors, to ensure Webb was in prime condition before beginning the major work of sunshield tensioning.

The process took eight days, and was by far the most complex such remote deployment ever attempted by an unmanned spacecraft. The shield is now in place to shade Webb from sunlight and heat and thus allow it to observe very faint infrared objects billions of light years away.

Next comes the deployment of Webb’s secondary mirror, followed by the unfolding of its main mirror.

Webb deployment resumes, with continuing success

9:50 am

After a day delay to assess the telescope’s earlier operation in space, engineers yesterday resumed the deployment of the James Webb Space Telescope’s sun shield.

First they began tensioning the shield’s first of five layers, completing that operation in about five and a half hours.

Next the engineers proceeded to tighten layers two and three, completing that task in about three hours.

Today they have begun tightening the last two layers. A live stream of this slow and relatively unexciting process (as long as nothing goes wrong) is available from NASA here.

Based on what has been done so far, it appears that the deployment of the sun shield, considered the most challenging part of Webb’s deployment, is going to complete successfully. While the unfolding and deployment of the mirror still must be done, getting the sun shield deployed eliminates one of the great concerns that has kept both astronomers and engineers awake nights for decades.

The unfurling of Webb’s sun shield begins

5:18 pm

Engineers have begun the multi-day unfurling and deployment of the sun shield on the James Webb Space Telescope.

The first step is to deploy two booms on each side of the telescope that draw the shield itself outward.

The deployment of the first boom was held up several hours to give engineers time to make sure the protective covers had, in fact, rolled off to the side of the sunshade pallets as required.

“Switches that should have indicated that the cover rolled up did not trigger when they were supposed to,” NASA said in a blog post. “However, secondary and tertiary sources offered confirmation that it had.”

“The deployment of the five telescoping segments of the motor-driven mid-boom began around 1:30 p.m., and the arm extended smoothly until it reached full deployment,” NASA said.

Engineers then sent commands to deploy the second sunshade boom, which extended smoothly and locked in place at 10:13 p.m., finally giving Webb its iconic kite-like shape.

Next the shield has to be tightened in place, which will also separate and tighten in place the shield’s five layers. According to the schedule, the four layers will be tensioned today, with the fifth tomorrow.

The step-by-step deployment is outlined in detail here, and updates to the most recently completed step after it is finished.

1st stage of Webb sun shield deployment completed

9:29 am

The deployment of the forward and aft pallets required to support the sun shield for the James Webb Space Telescope has apparently been successfully completed.

The link takes you to the website that outlines each step in Webb’s entire 30-day deployment sequence, and is updated to show you the next required step as the process continues. Though I have yet to see any official announcement, this page now shows that both pallets have successfully unfolded and that the next step is removal of the covers that have protected the sun shield membrene during assembly and launch.
