NASA’s safety panel questions NASA commitment to commercial space stations

10:18 am

We’re here to help you! Not surprisingly, members of NASA’s safety panel have once again expressed doubts about NASA’s ongoing effort to encourage a thriving private, competitive, and efficient commercial space industry, this time questioning the transition from NASA’s government-built space station, ISS, to privately-built and owned space stations, four of which are presently under development.

At a July 21 meeting of the Aerospace Safety Advisory Panel, members said they were concerned that commercial stations whose development is being supported by NASA were unlikely to be ready in time before the ISS is retired at the end of the decade, and that those efforts suffered from insufficient budgets.

Those plans, called Commercial Leo Earth Orbit (LEO) Destinations by NASA, “are on a precarious trajectory to realization on a schedule and within the projected resources needed to maintain a NASA LEO presence,” said Patricia Sanders, chair of the panel. “This is an area of concern for us.”

The panelists also questioned how quickly the stations would be man-rated (claiming NASA was not allocating enough time to do so) as well as whether NASA had enough work for four stations.

For the past decade this safety panel has consistently shown itself to be hostile to the new commercial space companies. It has never seen any safety issues or scheduling problems with NASA’s big SLS rocket. Nor did it notice Boeing’s significant software and valve problems on Starliner. Yet somehow, the work of SpaceX was dangerous (when it was not), and now these new stations, most of which are being built by new space companies, are equally unfit for use.

It is time to shut down this panel. Or at a minimum fire its present members and bring in new blood more willing to look at the entire space industry with a more objective eye.

Draper wins NASA contract to put a lander on the Moon’s far side

9:28 am

Capitalism in space: NASA yesterday awarded a $73 million contract to the space company Draper to place a lander on the Moon’s far side by 2025.

The lander, called SERIES-2 by Draper, will deliver to Schrödinger Basin three experiments to collect seismic data, measure the heat flow and electrical conductivity of the lunar subsurface and measure electromagnetic phenomena created by the interaction of the solar wind and plasma with the lunar surface.

The mission is the eighth NASA has awarded to date as part of CLPS, but the first to go to the lunar farside. The only mission by any country to land on the far side of the moon is China’s Chang’e-4 mission, which successfully landed in Von Kármán Crater in January 2019 and deployed the Yutu 2 rover that remains operational today.

With this award, there are presently five American companies with contracts to put landers on the Moon, Intuitive Machines, Astrobotic, Firefly, and Masten. Masten however shut down operations recently. This new contract to Draper for almost the exact same amount that had been awarded to Masten appears to replace Masten in the program.

NASA sets tentative launch date for SLS

9:46 am

NASA yesterday announced that it is targeting August 29, 2022 for the first unmanned launch of its SLS rocket.

NASA is tentatively targeting Aug. 29 for the long-awaited maiden flight of the agency’s huge Space Launch System moon rocket, officials said Wednesday. But they cautioned major challenges remain for the oft-delayed rocket and an official date will not be set until later.

As it stands, the launch processing schedule is extremely tight and depends on successful checkout of a repaired hydrogen line fitting, good results from end-to-end pre-flight checks of the rocket’s myriad other systems and getting everything done in time to haul it back out to the launch pad by around Aug. 18.

If any delays occur, this launch window extends until September 6th. If they can’t make that date, the next launch window opens on September 19th.

The mission, to send the Orion capsule around the Moon and back, would last 42 days and if launched as planned would return October 10th.

The announcement also slipped in this tidbit:

If the initial test flight goes well, NASA plans to launch four astronauts atop the second SLS rocket for an around-the-moon shakedown flight in 2024 — Artemis 2 — before sending the first woman and the first person of color to a landing near the moon’s south pole in 2025 or 2026 as part of the Artemis 3 mission. [emphasis mine]

This I think is the first time NASA officials have hinted that the launch might be delayed to ’26. It is no surprise, but as they have always done with SLS, they give these hints softly, prepping the press so that it doesn’t make news.

As for the disgraceful unseemly focus on race and sex, it appears that NASA is now an apartheid state. The make-up of missions will no longer be determined by skill and experience, but by ethnic considerations, with favoritism always given to minorities or women.

The May micrometeoroid impact on Webb’s mirror

9:37 am

Figure 3 from report

In a detailed report [pdf] of Webb’s overall excellent operational status following its in-space commissioning, the science team also included an analysis of the May 2022 micrometeoriod impact on one segment of Webb’s mirror.

The image to the right, taken from figure 3 of the report, shows the remaining alignment error of Webb’s entire mirror, after alignment. Except for that one bright spot in the segment to the lower right, all of the segments show excellent alignment, well within the range predicted before launch. The bright spot however is from the impact, and suggests that one mirror segment is significantly damaged. From the report:

The micrometeoroid which hit segment C3 in the period 22—24 May 2022 UT caused significant uncorrectable change in the overall figure of that segment. However, the effect was small at the full telescope level because only a small portion of the telescope area was affected. After two subsequent realignment steps, the telescope was aligned to a minimum of 59 nm rms, which is about 5-10 nm rms above the previous best wavefront error rms values 7 . It should be noted that the drifts and stability levels of the telescope mean that science observations will typically see telescope contribution between 60 nm rms (minimum) and 80 nm rms (where WF control will typically be performed). Further, the telescope WFE combines with the science instrument WFE to yield total observatory levels in the range 70-130 nm (see Table 2), so the slight increase to telescope WFE from this strike has a relatively smaller effect on total observatory WFE.

In plain English, the impact while damaging has not seriously reduced the telescope’s predicted capabilities.

However, to be hit with this size impact so soon after launch is very worrisome, especially because Webb’s mirror is not housed in any protective tube like Hubble or most telescopes. From the report:

It is not yet clear whether the May 2022 hit to segment C3 was a rare event (i.e. an unlucky early strike by a high kinetic energy micrometeoroid that statistically might occur only once in several years), or whether the telescope may be more susceptible to damage by micrometeoroids than pre-launch modeling predicted.

The science team is presently trying to anticipate what might happen if the impact rate turns out to be much higher than expected, and what can be done to mitigate the degradation of the mirror should more impacts occur.

NASA delays launch of its VIPER lunar rover to over concerns about commercial lander

8:58 am

VIPER's planned route on the Moon
VIPER’s planned route at the Moon’s south pole

In order to do more engineering tests of Astrobotic’s Griffin lunar lander, NASA has now delayed the launch of its VIPER lunar rover from November 2023 to November 2024.

NASA’s decision to pursue a 2024 delivery date results from the agency’s request to Astrobotic for additional ground testing of the company’s Griffin lunar lander, which will deliver VIPER to the lunar surface through CLPS. The additional tests aim to reduce the overall risk to VIPER’s delivery to the Moon. To complete the additional NASA-mandated tests of the Griffin lunar lander, an additional $67.8 million has been added to Astrobotic’s CLPS contract, which now totals $320.4 million.

Though the press release makes no mention of it, the launch of Astrobotic’s Griffin lander is partly dependent on the launch of Astrobotic’s first and smaller lunar lander, Peregrine, which was originally supposed to fly on the inaugural flight of ULA’s new Vulcan rocket, in 2021. That rocket’s first flight however has been delayed repeatedly because of delays by Blue Origin in completing development of the BE-4 rocket engine, to be used in Vulcan’s first stage. It is presently scheduled for early 2023, but that date remains tentative. This new delay of Griffin could be to make sure Peregrine flies first.

Regardless, this new budget increase means that the budget for Griffin has experienced a 62% cost overrun from its original $199 million number. This large increase in what is supposed to be a fixed price contract suggests that Astrobotic has been having some problems unstated by NASA, despite an inspector general report [pdf] that said all was going reasonably well.

Masten lays off staff, apparently shuts down

9:02 am

Capitalism in space: The small lunar lander company Masten Space Systems, which for years has worked to develop vertical rocket landing technology and has a $75.9 million contract with NASA to put a rover on the Moon, has apparently furloughed its staff and shut down operations.

The XL-1 lander was originally scheduled to launch in December 2022 bound for a landing at the moon’s south pole. In June 2021, Masten announced an 11-month launch delay to November 2023. The company said the delay was caused by industry-wide supply chain disruptions and the effects of the ongoing COVID-19 pandemic.

CLPS partners are expected to supplement NASA mission funding by carrying payloads for other parties. The source who requested anonymity said that is where Masten’s mission ran into problems. “We ran out of money after grossly underbidding. The estimate was $105 million but I was told that we had found a 30 million dollar private customer who wanted to fly with us,” the source said.

However, that customer later pulled out the venture. Subsequent attempts to fill the gap failed, the source added.

Masten is one of four companies with similar NASA lunar lander contracts. The others, Astrobotic, Firefly, and Intuitive Machines, all have scheduled missions planned, all of which however have been delayed for a variety of reasons.

Rogozin removed as Roscosmos’ head

8:52 am

Dmitry Rogozin, the head of Russia’s Roscosmos space corporation which controls the country’s entire aerospace industry, was fired yesterday and replaced by another former deputy prime minister, Yuri Borisov.

Don’t think Rogozin is out of favor with Putin however. Instead, it appears Putin wants his bull-headedness for running one of the regions Russia has conquered in the eastern Ukraine.

Following its tumultuous tenure as the head of Roskosmos, Rogozin was expected to move to the presidential administration and, possibly, lead it or “curate” the Russian occupation of the Eastern Ukraine, the independent Meduza publication reported.

I wonder if Rogozin’s removal is connected in any way with the ongoing negotiations between NASA and Russia’s foreign ministry for the barter agreement to allow the two to fly each other’s astronauts on each other’s capsules.

That agreement has been in negotiations and reviews for months by the two agencies as well as the U.S. State Department and Russian Foreign Ministry. NASA has long advocated for the agreement to enable what it calls “mixed crews” or “integrated crews” on spacecraft. That would ensure at least one NASA astronaut and one Roscosmos cosmonaut would be on the station should either Soyuz or commercial crew vehicles be unavailable for an extended period.

Rogozin’s bellicose manner has I think made those negotiations difficult. Putin might have decided, especially with the break up of its space partnership with Europe, to tone things down. Moreover, he might have realized that Rogozin’s contentious manner might be better put trying to take control of occupied Ukrainian territory.

More Webb images released

9:08 am

Southern Ring Nebula, as taken by Webb
Click for full image.

As planned, NASA this morning released four new science images from the James Webb Space Telescope, in addition to the deep field image released yesterday.

All are spectacular, with each producing new information not previously observed. To see the Stephen’s Quintet image go here. For the exoplanet data, showing the presence of water in its atmosphere, go here. For the Carina nebula image, go here.

The image to the right, reduced to post here, shows the Southern Ring Nebula as taken by two Webb cameras in different infrared wavelengths. From the press release:

Two stars, which are locked in a tight orbit, shape the local landscape. Webb’s infrared images feature new details in this complex system. The stars – and their layers of light – are prominent in the image from Webb’s Near-Infrared Camera (NIRCam) [at the top], while the image from Webb’s Mid-Infrared Instrument (MIRI) on the [bottom] shows for the first time that the second star is surrounded by dust. The brighter star is in an earlier stage of its stellar evolution and will probably eject its own planetary nebula in the future.

In the meantime, the brighter star influences the nebula’s appearance. As the pair continues to orbit one another, they “stir the pot” of gas and dust, causing asymmetrical patterns.

Because this is an infrared image, the colors are not natural, but were assigned based on the slightly different infrared wavelengths produced by the object’s different features. From the image’s webpage:

Several filters were used to sample narrow and broad wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter.

Eventually astronomers will use Webb to look at many astronomical objects that Hubble has been observing for the past thirty years, adding a high resolution infrared view that will add to Hubble’s views.

First science image released from Webb

3:40 pm

Webb's first deep field image
Click for original image.

The first science image from the James Webb Space Telescope has now been unveiled.

That image is to the right, reduced to post here. From the press release:

Known as Webb’s First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail. Thousands of galaxies – including the faintest objects ever observed in the infrared – have appeared in Webb’s view for the first time. This slice of the vast universe covers a patch of sky approximately the size of a grain of sand held at arm’s length by someone on the ground.

This deep field, taken by Webb’s Near-Infrared Camera (NIRCam), is a composite made from images at different wavelengths, totaling 12.5 hours – achieving depths at infrared wavelengths beyond the Hubble Space Telescope’s deepest fields, which took weeks.

The image shows the galaxy cluster SMACS 0723 as it appeared 4.6 billion years ago. The combined mass of this galaxy cluster acts as a gravitational lens, magnifying much more distant galaxies behind it. Webb’s NIRCam has brought those distant galaxies into sharp focus – they have tiny, faint structures that have never been seen before, including star clusters and diffuse features.

The smeared concentric arrangement of many reddish objects surrounding the picture’s center strongly suggests we are seeing distortion by the gravity of this galaxy cluster.

While nothing in this image appears at first glance to be different than many earlier Hubble images, it looks at objects in the infrared that are much farther away than anything ever seen before, farther than Hubble in the optical could see. To understand the new discoveries hidden in such an image will likely take several years of further research. For example, before astronomers can understand what this image shows they need to determine the red shift of each galaxy, thus roughly determining its distance and the overall 3D structure of the objects visible. Moreover, the consequences of the gravitational lensing must be unpacked.

The White House briefing itself was somewhat embarrassing to watch, as Vice President Kamala Harris, President Joe Biden, and NASA administrator Bill Nelson all struggled to explain what this image shows, and failed miserably. Moreover, the briefing had technical problems, started very late, and it appeared that Bill Nelson especially had no idea what he was looking at. The briefing also ended very abruptly when it shifted to reporters’ questions.

Engineers lose contact with CAPSTONE on its way to Moon

2:24 pm

Shortly after the spacecraft was successfully deployed from its Proton upper stage on yesterday, engineers lost contact with the spacecraft as it headed towards the Moon.

“The spacecraft team currently is working to understand the cause and re-establish contact. The team has good trajectory data for the spacecraft based on the first full and second partial ground station pass with the Deep Space Network,” NASA spokesperson Sarah Frazier wrote in an emailed statement today (July 5).

“If needed, the mission has enough fuel to delay the initial post-separation trajectory correction maneuver for several days,” Frazier added. “Additional updates will be provided as soon as possible.”

The spacecraft will not arrive in lunar orbit until November, but along the way it needs to do a number of course corrections. Thus, there is some time pressure to reestablishing communications. That task now falls with the private company Advanced Space, which won a contract to operate the spacecraft for NASA.

UPDATE: More details are provided by the operators of the spacecraft, Advanced Space press, here. Though they canceled a course correction burn today, they apparently have plenty of time to do it, since the probe is already on a course to reach lunar orbit. The burn was simply intended to increase the accuracy of the trajectory.

Food fight! China denies NASA chief’s charge that it wants to dominate space

9:16 am

On July 2, 2022, in an interview for a German news outlet, NASA administrator described in somewhat overbroad terms the long range goals of the Chinese space program.

“We must be very concerned that China is landing on the moon and saying: ‘It’s ours now and you stay out,’” Mr. Nelson said in an interview published Saturday in the German newspaper Bild.

….China’s space program, at its heart, is a military space program, Mr. Nelson said. “China is good. But China is also good because they steal ideas and technology from others,” he said, according to Bild.

A China spokesman for its Foreign Ministry, Zhao Lijian, immediately slammed Nelson’s comments, adding some of his own overbroad accusations against the U.S.

Rocket Lab’s Photon completes course corrections, deploys CAPSTONE to Moon

8:45 am

Capitalism in space: Rocket Lab’s Photon upper stage successfully completed its seventh engine burn, putting NASA’s cubesat test lunar orbital on a path toward the Moon.

Following its launch on June 28, CAPSTONE orbited Earth attached to Rocket Lab’s Photon upper stage, which maneuvered CAPSTONE into position for its journey to the Moon. Over the past six days, Photon’s engines fired seven times at key moments to raise the orbit’s highest point to around 810,000 miles from Earth before releasing the CAPSTONE CubeSat on its ballistic lunar transfer trajectory to the Moon. The spacecraft is now being flown by the teams at Advanced Space and Terran Orbital. [emphasis mine]

From here on out CAPSTONE will use its own tiny thrusters to do any course corrections as it heads for an arrival in lunar orbit on November 13, 2022.

The highlighted words in the quote above are significant in and of themselves. The spacecraft is not being operated by NASA. In fact, other than paying for it, NASA has little to do with CAPSTONE. It was designed and built by Terran Orbital. It was launched by Rocket Lab. And it is now being controlled by Advanced Space, a private commercial company focused on providing in-space operations for others.

Rocket Lab’s Photon upper stage completes 3rd of 7 engine firings to get CAPSTONE to Moon

9:37 am

Rocket Lab’s Photon upper stage has now successfully completed the third of seven planned engine burns designed to slowly raise the Earth orbit of NASA’s experimental lunar cubesat CAPSTONE so that it can eventually be sent towards the Moon.

Lunar Photon’s HyperCurie engine will perform a series of orbit raising maneuvers by igniting periodically to increase Photon’s velocity, stretching its orbit into a prominent ellipse around Earth. Six days after launch, HyperCurie will ignite one final time, accelerating Photon Lunar to 24,500 mph (39,500 km/h) and setting it on a ballistic lunar transfer. Within 20 minutes of this final burn, Photon will release CAPSTONE into space for the first leg of the CubeSat’s solo flight. CAPSTONE’s journey to NRHO is expected to take around four months from this point. Assisted by the Sun’s gravity, CAPSTONE will reach a distance of 963,000 miles from Earth – more than three times the distance between Earth and the Moon – before being pulled back towards the Earth-Moon system.

Once in lunar orbit, CAPSTONE will be used to both test operations in that orbit (similar to the one NASA’s Lunar Gateway space station will use) while also demonstrating the use of a cubesat on an interplanetary mission.

China and Rocket Lab complete successful launches

8:51 am

Two launches this morning herald the upcoming busy launch schedule for the last few days of June.

First China launched from its Jiuquan interior spaceport an Earth observation satellite using its Long March 4C rocket. As is usual with China, the first stage crashed on land, though no details have been provided.

Next, Rocket Lab used its Electron rocket to send NASA’s CAPSTONE cubesat lunar probe on its way to the Moon. More information here.

CAPSTONE is currently in low-Earth orbit, and it will take the spacecraft about four months to reach its targeted lunar orbit.

…CAPSTONE is attached to Rocket Lab’s Lunar Photon, an interplanetary third stage that will send CAPSTONE on its way to deep space. Shortly after launch, Lunar Photon separated from Electron’s second stage. Over the next six days, Photon’s engine will periodically ignite to accelerate it beyond low-Earth orbit, where Photon will release the CubeSat on a ballistic lunar transfer trajectory to the Moon. CAPSTONE will then use its own propulsion and the Sun’s gravity to navigate the rest of the way to the Moon. The gravity-driven track will dramatically reduce the amount of fuel the CubeSat needs to get to the Moon.

Once at the Moon, the spacecraft will enter a polar orbit varying from 1000 to 43,500 miles from the surface, with its prime mission to test operations in that lunar orbit.

Not only did NASA hire a private company, Rocket Lab, to launch it, the agency also hired a private company, Terran Orbital, to build it.

The leaders in the 2022 launch race:

26 SpaceX
21 China
8 Russia
4 Rocket Lab

American private enterprise still leads China 36 to 21 in the national rankings, and the entire world combined 36 to 34.

For the rest of June, the American companies SpaceX, Virgin Orbit, and ULA all have planned launches, as well as India. If all succeed, that would put the total launches in the first half of ’22 at 74, a pace that would almost reach 150 launches by the end of the year, smashing the annual record set last year. The U.S.’s pace in turn is likely to exceed the number of launches it completed in all of ’22 in July, with the possibility it could complete 75-80 launches by the end of the year, exceeding the U.S. annual record of 70 set in 1966.

NASA completes suborbital launch from commercial spaceport in Australia

8:59 am

Early this morning NASA successfully completed its first rocket launch from Australia since 1995, launching a suborbital payload from a new commercial spaceport on the northern coast of Australia.

The rocket is Nasa’s first of three to blast off from the newly constructed Arnhem Space Centre on the edge of the Northern Territory. Scientists hope it will help them study the impact of a star’s light on the habitability of nearby planets.

Onlookers who travelled to the remote site glimpsed the rocket for only about 10 seconds before it shot out of view.

After a short fifteen minute flight the sounding rocket and payload were recovered. The next suborbital launch is scheduled for July 4th.

Cygnus freighter fires engine, adjusts ISS orbit for first time

9:47 am

For the first time the engines on a Cygnus capsule were used successfully yesterday to adjust the orbit of the International Space Station (ISS).

On Saturday, June 25, Northrop Grumman’s Cygnus completed its first limited reboost of the International Space Station. Cygnus’ gimbaled delta velocity engine was used to adjust the space station’s orbit through a reboost of the altitude of the space station. The maneuver lasted 5 minutes, 1 second and raised the station’s altitude 1/10 of a mile at apogee and 5/10 of a mile at perigee. This Cygnus mission is the first to feature this enhanced capability as a standard service for NASA, following a test of the maneuver which was performed in 2018 during Cygnus’s ninth resupply mission.

NASA’s goal is to have this capability without relying on Russia’s Progress capsules, which up until now have been used to adjust the station’s orbit. It appears from yesterday’s test this this goal has now been met.

Psyche will not launch as scheduled

9:06 am

NASA officials yesterday confirmed that because of software issues its asteroid mission Psyche will not launch as scheduled this year.

Due to the late delivery of the spacecraft’s flight software and testing equipment, NASA does not have sufficient time to complete the testing needed ahead of its remaining launch period this year, which ends on Oct. 11. The mission team needs more time to ensure that the software will function properly in flight.

…As the mission team at NASA’s Jet Propulsion Laboratory in Southern California began testing the system, a compatibility issue was discovered with the software’s testbed simulators. In May, NASA shifted the mission’s targeted launch date from Aug. 1 to no earlier than Sept. 20 to accommodate the work needed. The issue with the testbeds has been identified and corrected; however, there is not enough time to complete a full checkout of the software for a launch this year.

NASA management will conduct a review to understand what caused the problem.

As for when Psyche can next launch and reach the asteroid Psyche, the next launch windows in ’23 and ’24 will not arrive at the asteroid until ’29 or ’30 respectively, a flight time that is about two years longer than what the ’22 launch would have been.

NASA now targeting late August launch of SLS

11:35 am

NASA officials today confirmed that they are satisfied with the results from this week’s incomplete dress rehearsal countdown of the SLS rocket, and are targeting a late August launch of SLS.

NASA officials have reviewed the data collected during the test run and decided that a leaky hydrogen valve was not significant enough to force a delay in the launch of Artemis I, an uncrewed mission planning to orbit the moon and return to Earth. It’s the first step toward putting humans back on the moon for the first time since Apollo 17 in 1972.

“The team is now ready to take the next step and prepare for launch,” said NASA’s deputy associate administrator Tom Whitmeyer.

NASA officials said they will roll the massive Space Launch System rocket back to the Vehicle Assembly Building, where the valve’s faulty seal will be replaced. Rollback is slated for Friday July 1, though weather concerns could push that back.

SLS won the five-plus year race with the Webb telescope on which would have the most delays and launch last. Now the race will be between SLS and SpaceX’s Starship/Superheavy. Which will launch first this summer? In a rational world, SLS should win hands down. It has been in development since 2004, while Starship only began design work in 2017.

This is not a rational world, however, and SLS’s long gestation had little to do with designing a rocket and everything to do with politics and a corrupt Congress and an incompetent NASA. The rocket that has come out of this is thus difficult to operate and incredibly cumbersome. Its components have also not been tested thoroughly.

SpaceX meanwhile has been designing and building its heavy-lift rocket with only one goal: the rocket must be efficient to operate.

I predict Starship will reach orbit first, though if it doesn’t it most likely will be because SpaceX finds it needs to do more ground tests and revisions, not because SLS has surged ahead. And regardless, Starship will likely fly many times in the next three years, while SLS will only get off the ground once.

More important, the chances of SLS and Orion working perfectly throughout that that lunar orbit mission seem almost impossible, based on track record during the past eighteen years of both programs. Expect some issues to crop up, first during the launch countdown, forcing several scrubs, and then during the mission itself. None might be mortal, but all will raise questions whether it would be wise to put humans on this rocket and capsule on its next flight, and attempt to take them to the Moon.

NASA halts sale of Apollo 11 Moon dust, claiming ownership

10:37 am

We’re here to help you: The auction of a tiny amount of Moon dust brought back by Apollo 11 and used in a post-flight experiment using German cockroaches has been canceled because NASA claimed ownership of that dust and demanded its return.

“NASA asserts legal ownership of the materials consisting of the Apollo 11 lunar dust experiment … based upon the information and documentation provided in the description of the lot and evidence regarding NASA’s contemporaneous contracting practices,” an attorney in NASA’s Office of the General Counsel wrote RR Auction in a letter on Wednesday, a week after first reaching out to the firm. “It is clear and undeniable that the materials consisting of the experiment are owned by NASA.”

The lot under contention comprises what remains from the late Marion Brooks’ research into the physiological effects of lunar material on Blattellas germanica, or German cockroaches. The insects had been fed moon dust by NASA scientists in the immediate aftermath of the 1969 Apollo 11 lunar landing mission. After no ill-effects were seen while astronauts Neil Armstrong, Buzz Aldrin and Michael Collins were held in quarantine, the (now dead) cockroaches were handed off to Brooks, an entomologist from the University of St. Paul, for more thorough study.

Included in the auction was a small vial of moon dust that Brooks’ had carefully extracted from the cockroaches’ corpses, as well as three of the remaining (dead) cockroaches and two boxes of tissue slides for microscopic study.

It appears the dust had been in the Brooks family possession for more than forty years, then sold by them at auction in 2010 for $10,000. Under standard adverse possession law, you lose ownership if you don’t claim that right after twenty years. It would thus seem that NASA’s claim is bogus.

But then, NASA as a government agency doesn’t believe the standard laws apply to it. It continues to demand that all Apollo lunar material belongs to it and be returned, no matter what the circumstances it was originally handed out by the agency and no matter how long ago.

NASA blocks Starship/Superheavy launches at SpaceX’s new Florida launchpad

9:37 am

Capitalism in space: NASA officials revealed yesterday that it will not allow any Starship/Superheavy launches at SpaceX’s new Florida launchpad, at least for the moment, because of the threat a launchpad failure might have on the launchpad SpaceX uses to launch manned Falcon 9 missions to ISS.

The NASA statement said the agency “is responsible for ensuring SpaceX remains compliant with the requirements of the property agreement for the use of Launch Complex 39A.”

“These requirements include those related to construction, safety and environmental conditions,” the statement said. “At this time, NASA has only provided approval to build. Additional review for hazards, operational impacts and supportability will be required prior to a launch.”

The new Starship launchpad is 1,000 feet away from pad 39A, which is SpaceX’s manned Dragon launchpad. NASA management thinks this is too close. However, the managers have also not ruled out future launches, only that they wish to do a thorough review of the issue with SpaceX.

Because NASA and the federal government is also relying on Starship to land its astronauts on the Moon, it can’t block Starship flights outright. It could be however that this issue might shift Starship operations back to Boca Chica, after federal government opposition there forced SpaceX to shift more operations to Florida.

In other words, the government wants its cake and eat it to. Some factions within the Biden administration and the Washington bureaucracy want to block Starship, others want it to fly. The result is a tug-of war, with SpaceX in the middle.

Psyche software issue could prevent launch this year

9:08 am

In a remarkably brief announcement on the Psyche website, the engineering team suggested that the flight software issue that forced a seven week delay in its launch might now prevent a launch this year.

This is the entire announcement:

NASA’s Psyche mission team continues to assess ongoing issues with the spacecraft’s flight software. The team is evaluating its ability to meet a schedule to launch in 2022 – the current launch period is Sept. 20 to Oct. 11. If it is determined that launch in 2022 is not possible, a full range of actions for how to proceed will be considered.

This year’s launch window would have gotten the spacecraft to the asteroid Psyche in 2026. Since this flight path required a fly-by of Mars, it is very unclear when another launch window will be available.

SLS dress rehearsal countdown ends at T-29 seconds

NASA’s fourth attempt to complete a full dress rehearsal countdown of its giant SLS rocket today ended at T-29 seconds, just short of the complete countdown.

It appears the countdown had one issue — a hydrogen fuel leak at the point where the umbilical fuel line attaches to the rocket — that mission control decided to ignore (or “mask” to use their word) so that they could proceed into the count as far as possible. It was this decision however that caused the two-hour delay in the countdown. They then resumed the countdown at T-10 minutes, the beginning of terminal count.

During the terminal count, the teams performed several critical operations that must be accomplished for launch including switching control from the ground launch sequencer to the automated launch sequencer controlled by the rocket’s flight software, and important step that the team wanted to accomplish.

NASA will hold a press conference tomorrow at 11 am (Eastern) to discuss the results of this dress rehearsal. While the leak is concerning, I expect NASA to decide that this dress rehearsal was a success, that they will roll the rocket back to the vehicle assembly building where they will fix this problem, after which the agency will declare the rocket ready to launch by the end of August.

While risky, doing otherwise likely raises other risks. If they decide to do another dress rehearsal the launch faces more delays. And waiting much longer continues to increase the danger that the solid rocket side boosters will not function as intended because they have been stacked almost a year longer than their accepted use-by date.

If this turns out to be the plan, expect the actual launch countdown to be as plagued with issues and delays and scrubs. NASA has yet to demonstrate it can do this smoothly with no problems. Worse, this level of mediocre performance has been par for the course for this entire SLS program.

If that launch should go smoothly it will be a welcome and unprecedented event.

SLS dress rehearsal countdown continues, though T-0 delayed two hours

9:33 am

The SLS dress rehearsal countdown is proceeding today as planned, though the countdown’s end at T-0 is now 4:38 pm (eastern), two hours later than previously announced.

Apparently they have delayed T-0 from the beginning of the two-hour simulated launch window to its end. This decision so early in the count suggests the launch team wants to give itself extra time either to deal with some issue that has come up that they haven’t told us about yet, or to give themselves more time in case some issue should come up.

SLS dress rehearsal countdown begins

10:07 am

NASA engineers began their fourth attempt to complete a full dress rehearsal countdown of the SLS rocket yesterday, with everything proceeding so far as planned.

Overnight, engineers powered up the Orion spacecraft and the Space Launch System’s core stage. Teams also configured several systems on the ground, rocket, and spacecraft and performed activities to prepare umbilicals that connect the rocket and spacecraft to the mobile launcher and are used to provide power, communications, coolant, and propellant.

Actual fueling begins tomorrow, when the countdown is supposed to conclude at T-0 at 2:40 pm (Eastern).

NASA shuffles crew for first Starliner manned mission

8:48 am

In a press release yesterday, NASA announced the two-person crew that will fly on the first manned mission of Boeing’s Starliner capsule to ISS.

[C]ommander Barry “Butch” Wilmore, whom NASA assigned to the prime crew in October 2020, will join NASA astronaut Suni Williams, who will serve as pilot. Williams previously served as the backup test pilot for CFT [crew test flight] while assigned as commander of NASA’s Boeing Starliner-1 mission, Starliner’s first post-certification mission. As CFT pilot, Williams takes the place of NASA astronaut Nicole Mann, originally assigned to the mission in 2018. NASA reassigned Mann to the agency’s SpaceX Crew-5 mission in 2021.

The crew for this flight, delayed now more than two years, has changed several times. In 2020 astronaut Chris Ferguson dropped out for personal reasons. Then NASA listed the crew as Wilmore, Mike Finke, and Nicole Mann, with Williams then assigned to Starliner’s next mission, its first long term flight to ISS.

With this change, the crew has been reduced to two, and Finke is now listed as a backup should something further change with the prime crew.

The press release made no mention of an actual launch date, though it did say that Boeing and NASA are still reviewing the data from Starliner’s unmanned demo mission:

The Starliner team is in the process of delivering the initial test flight data to NASA and jointly determining forward work ahead of a crewed flight. These engineering and program reviews are expected to continue for several weeks, culminating in a launch schedule assessment at the end of July, based upon spacecraft readiness, space station scheduling needs, and Eastern Range availability.

The goal had been to fly before the end of this year. It appears NASA and Boeing are still pushing to meet that goal.

SLS dress rehearsal countdown set for June 20th with launch delayed again

9:28 am

According to NASA officials, the next attempt to complete a dress rehearsal countdown for its SLS rocket will take place on June 20, 2022, with the earliest date an actual launch can occur delayed again, and now set at best for an August 23 to September 6 window.

The article also notes that during a different press conference, NASA administrator Bill Nelson hinted that “there could be slips” in the present target date of ‘2025 for landing humans on the Moon.

Ya think? I guarantee that NASA will not land humans on the Moon in ’25, at least not using SLS. Based on all the issues confronting SLS, as well as NASA’s normal way of doing things, this mission will certainly slip at least one to two more years. And I am being very very very very optimistic.

We must also note that when first proposed by Bush Jr. in 2004, he predicted a NASA manned lunar landing by 2015, which means this launch will be at least one decade behind schedule, with it more likely being later than that.

But then, I can hear our glorious president yelling at me for complaining. “C’mon man! What’s a decade or two when you’re scheduling something important?”

Russian government gives Roscosmos permission to negotiate astronaut barter deal

8:00 pm

The Russian prime minister yesterday signed a decree giving Roscosmos permission to negotiate a astronaut exchange deal with NASA, whereby for every American that flies on a Soyuz to ISS one Russian would fly on either a Dragon or Starliner capsule.

NASA has been pushing for this arrangement for about a year, but Russia was at first skittish about flying on Dragon. Then its invasion of the Ukraine raised further barriers. Now that it is clear the Russians have no options in space but to stick with ISS for at least the next few years, the Russian government has relented and will allow this barter arrangement to go forward.

NASA had been pushing to put the first Russian on a Dragon in the fall. That flight is now likely to happen.

Of course, all this could change should things change drastically in the Ukraine. The partnership on ISS remains quite fragile politically, even if the astronauts and engineers and workers of both sides continue to work together well.

SLS’s 2nd mobile launcher to cost more than $1.5 billion, 3x what was initially budgeted

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

According to an inspector general report [pdf] released today, the second mobile launcher being built by the company Bechtel to transport its SLS rocket from the assembly building to the launch site is likely going to cost more than $1.5 billion, three times what was initially budgeted, and will not be completed any earlier than the end of 2027, four years behind schedule.

Compounding Bechtel’s projected cost increases and schedule delays, an ML-2 [mobile launcher-2] project analysis provided only a 3.9 percent confidence level that the nearly $1 billion cost [twice the original budget] and October 2025 [2.5 years late] delivery estimates were accurate. NASA requires projects to develop budgets and schedules consistent with a 70 percent joint cost and schedule confidence level (JCL), meaning a 70 percent likelihood the project will finish equal to or less than the planned costs and schedule. In fact, an Independent Review Team analysis determined the project would require an additional $447 million and 27 months, for a total contract value of $1.5 billion and a launcher delivery date of December 2027—a schedule that would enable an Artemis IV launch no earlier than the end of 2028.

The first mobile launcher, shown on the left in the graphic, cost more than $1 billion and will used only three times, at most. The second, on the right, is required for all of the assigned interplanetary tasks being given to the full size version of SLS beyond those first three test flights. Without it that version of SLS cannot launch. And even if the launcher is ready by 2028, as the IG report suggests, that will be more than a decade behind schedule, and six years from now.
