SLS launch delayed until August, at the earliest

In describing its plans for doing a second dress rehearsal countdown of its SLS rocket in June, NASA officials yesterday noted that they have delayed the actual launch until an August launch window so they will have time to do a third dress rehearsal before that launch.

But Free warned the issues are complex and it’s possible more than one tanking test will be required to thoroughly test the complex systems in the SLS rocket and their interaction with the ground systems that provide propellants, power and other critical elements. He said the August launch windows would “allow us to do two wet dress rehearsal attempts if we need them.”

“We are optimistic that we only need one more based on everything we’ve been able to do thus far to fine tune our tanking procedures,” he said. “But we also want to be realistic and upfront with you that it may take more than one attempt to get the procedures where we need them.”

According to this SpacePolicyOnline report, NASA has also mapped out additional launch windows for September through December.

In reviewing every news story about yesterday’s press conference, I could not find any that asked the agency about the status of SLS’s two solid rocket strap-on boosters. Both have now been stacked for more than seventeen months, and by August will have been stacked for twenty months, eight months past NASA’s use-by rule of one year. Either the past rules were too conservative, or NASA is simply ignoring the possibility that those boosters might no longer be viable. In either case, it is disappointing no reporter asked about this.

NASA to conduct second SLS launch dress rehearsal in June

In announcing a press conference later today about the status of NASA’s SLS rocket, the agency revealed it now plans to conduct a second SLS launch dress rehearsal in June.

NASA’s SLS rocket and Orion spacecraft arrived back at Kennedy’s Vehicle Assembly Building April 26 after a 10-hour journey from launch pad 39B. Since their arrival, teams have worked to replace a faulty upper stage check valve and repair a small leak within the tail service mast umbilical ground plate housing. The teams also have been performing additional checkouts while the spaceport’s supplier of gaseous nitrogen makes upgrades to their pipeline configuration to support Artemis I activities.

We will likely find out NASA’s new launch schedule for the rocket today.

ESA: ExoMars will likely be delayed till ’28 at the soonest

An official of the European Space Agency (ESA) at a May 3rd science meeting announced that the launch of its ExoMars rover will likely be delayed until 2028 at the earliest because of the partnership breakup with Russia due to its invasion of the Ukraine.

Russia had been providing both the launch rocket as well as the lander on Mars.

Speaking at a May 3 meeting of NASA’s Mars Exploration Program Analysis Group (MEPAG), Jorge Vago, ExoMars project scientist at ESA, said he doubted a new lander could be ready by 2026. “It is theoretically possible, but in practice we think it would be very difficult to reconfigure ourselves and produce our own lander for 2026,” he said. “Realistically, we would be looking at a launch in 2028.”

Launching in 2028 could pose technical challenges for ExoMars. One trajectory would get the rover to Mars relatively quickly, but have it arrive just a month before dust storm seasons starts at the preferred landing site. An alternative trajectory would require traveling for more than two years to each Mars, but get the rover there six months before dust storms start.

“We have been trying very hard to convince the engineering team that the dust storm season is not death,” Vago said. “We should concentrate on making the rover more robust and able to weather a dust storm.”

There are other issues. The rover will need new radioisotope heating units, or RHUs, to provide power, since Russia will no longer providing them. If the U.S. provides, the launch for security reasons will have to take place in the U.S., which means the launch provider will have to be American.

The delay to ’28 also could cause the ExoMars rover mission to be completely changed, repurposed to become part of the sample return mission that the ESA and NASA are partnering to bring back the cached samples that Perseverance is gathering. If so, this repurposing might delay its launch to Mars even further.

Biden’s NASA administrator slams the cost-plus contracts he endorsed when he was a senator

Bill Nelson, Biden’s NASA administrator and a former Democratic Party senator from Florida, made it clear during his testimony before a subcommittee of the Senate Appropriations committee today that he condemns cost-plus contracts and no longer wants to use them for any NASA project, even though he demanded NASA use such contracts when he was a senator.

Nelson was asked what, in his opinion, was the biggest threat to NASA’s goal of landing humans on the Moon by 2025. Nelson responded that the agency needed competition in its program to develop a Human Landing System. In other words, he wanted Congress to support NASA’s request for funding to develop a second lander alongside SpaceX’s Starship vehicle.

But Nelson didn’t stop there. He said Congress needs to fund this lander contract with a fixed-price award, which only pays companies when they reach milestones. This contracting mechanism is relatively new for the space agency, which traditionally has used “cost-plus” contracts for large development programs. Such awards pay contractors their expenses, plus a fee. “I believe that that is the plan that can bring us all the value of competition,” Nelson said of fixed-price contracts. “You get it done with that competitive spirit. You get it done cheaper, and that allows us to move away from what has been a plague on us in the past, which is a cost-plus contract, and move to an existing contractual price.”

The significance of Nelson’s remarks is that it bluntly signals that the Biden administration has now wholly bought into the ideas I put forth in Capitalism in Space. Nelson wants NASA to be a customer that buys what it needs from the private sector, and to do it as inexpensively as possible. He also wants to encourage competition by allowing that private sector to own and control what it builds.

In the past, a new administration would have abandoned the policies of the past administration. Instead, the Biden administration is accelerating the Trump administration’s policy of encouraging private enterprise and eliminating cost-plus contracts.

The future of the American space industry appears bright indeed.

This statement by Nelson also indicates that the future of SLS is now very precarious, especially because it is being built almost entirely on cost-plus contracts. Any serious failure could kill it. And even if its next launch succeeds, further launches hang now by a very thin political thread. And the more success private space has, the thinner that thread will become.

Update on Dream Chaser

Link here.

Overall progress has been incredibly slow, considering the NASA contract to build this was awarded in 2016. Sierra Space is only building one spacecraft, designed to be reusable. For six years to have passed and the spacecraft, dubbed Tenacity, is still a year away from flight, seems excessive, especially because the spaceplane is small. It took SpaceX only four years to go from concept to successfully landing first stages. Starship began test flights only three years after the project began.

Still, the spaceplane is moving forward. Hopefully by February ’23 it will finally fly, giving the U.S. another method besides Dragon for getting cargo to and from space. That it might do so before Boeing’s Starliner is somewhat ironic, and puts more pressure on that company to get that capsule operational.

NASA decides to end airborne SOFIA telescope operations

According to a joint announcement yesterday from NASA and the German space agency DLR, all operations of the airborne astronomy telescope SOFIA will end as of September ’22.

NASA has been trying to cancel this project for several years, because its capabilities have not justified its expense, about $85 million per year. Congress has repeatedly refused to go along, reinserting funding after NASA tried to delete it. That the astronomy community itself suggested in November that the project be canceled, however, probably means this Congress will likely go along with this most recent announcement.

SpaceX successfully launches 4 astronauts into orbit

Capitalism in space: SpaceX early this morning successfully used its Falcon 9 rocket to launch its new capsule, Freedom, carrying four astronauts into orbit and heading to a docking with ISS this evening.

The first stage successfully landed on the drone ship in the Atlantic, completing its fourth flight.

The leaders in the 2022 launch race:

16 SpaceX
11 China
5 Russia
2 ULA
2 Rocket Lab

The U.S. now leads China 23 to 11 in the national rankings. In fact, at this moment the U.S. leads all other nations combined, 23 to 19.

Watch first flight of SpaceX’s fourth capsule, Freedom, carrying four NASA astronauts

The next launch of a NASA crew to ISS is scheduled to occur tonight at 3:52 am (Eastern) using SpaceX’s new capsule, Freedom, the fourth in the company’s fleet of manned spacecraft. Note too that the first stage of this Falcon 9 rocket will be making its fourth flight into space.

I have embedded the live stream below. As I write this, at 1:19 am (Eastern) the crew has just entered the capsule. Go here for details about the flight, which will be a five month mission.

Commander Kjell Lindgren, veteran of one previous expedition on the space station, leads the four-person crew awaiting liftoff Wednesday. He will be joined by pilot Bob Hines and mission specialist Jessica Watkins, two first-time fliers from NASA’s astronaut corps. European Space Agency astronaut Samantha Cristoforetti, a native of Italy who spent nearly 200 days in orbit in 2014 and 2015, rounds out the crew.

If the launch goes well, Freedom will dock with ISS about sixteen hours later.

If you watch, I must once again note that every person you see aiding the astronauts will be a SpaceX employee. Except for some of the announcers and NASA’s mission control for operating ISS, the launch mission control and everything else is run by this privately owned commercial company.

SLS rocket rolled back to VAB

NASA’s SLS rocket has now been rolled back to the vehicle assembly building (VAB) so that engineers can assess the various problems that prevented the agency from completing a full dress rehearsal countdown last week.

Over the next several days, the team will extend the work platforms to allow access to SLS and Orion. In the coming weeks, teams will work on replacing a faulty upper stage check valve and a small leak within the tail service mast umbilical ground plate housing, and perform additional checkouts before returning to the launch pad for the next wet dress rehearsal attempt.

More details about these problems can be found here.

The bottom line is that these engineering fixes are certain to take at least two months to fix. Then NASA must decide what next to do. If it decides to redo the dress rehearsal countdown, then an actual launch cannot happen sooner than July, and only if they proceed directly to launch after completing the rehearsal. If the rocket is rolled back to the VAB after the next rehearsal the launch will be delayed further, into August or September.

And all that assumes the next rehearsal goes perfect, something that seems unlikely based on what has happened so far.

The delays are a problem because the first stage’s two strap-on solid rocket boosters are already well past their “use-by” date of January ’22. The possibility that NASA will have to unstack this rocket and replace these boosters is growing. If that happens the launch cannot occur sooner than early ’23, if then.

Worse, these delays cause all other subsequent SLS launches to be delayed as well. Right now the manned mission to the Moon, presently scheduled for ’25, is likely going to be pushed back to ’26.

NASA extends eight planetary missions, including sending OSIRIS-REx to the asteroid Apophis

Apophis' path past the Earth in 2029
Apophis’ path past the Earth in 2029.

NASA today announced that it is extending the missions of eight different planetary probes.

The missions – Mars Odyssey, Mars Reconnaissance Orbiter, MAVEN, Mars Science Laboratory (Curiosity rover), InSight lander, Lunar Reconnaissance Orbiter, OSIRIS-REx, and New Horizons – have been selected for continuation, assuming their spacecraft remain healthy. Most of the missions will be extended for three years; however, OSIRIS-REx will be continued for nine years in order to reach a new destination, and InSight will be continued until the end of 2022, unless the spacecraft’s electrical power allows for longer operations.

The biggest news is the decision to extend OSIRS-REx so that it can rendezvous with the asteroid Apophis in 2029. The science team…

…will redirect the spacecraft to encounter Apophis, an asteroid roughly 1,200 feet (roughly 370 meters) in diameter that will come within 20,000 miles (32,000 kilometers) of Earth in 2029. OSIRIS-APEX will enter orbit around Apophis soon after the asteroid’s Earth flyby, providing an unprecedented close-up look at this S-type asteroid. It plans to study changes in the asteroid caused by its close flyby of Earth and use the spacecraft’s gas thrusters to attempt to dislodge and study the dust and small rocks on and below Apophis’ surface.

Apophis is a potentially dangerous asteroid, with a 1 in 150,000 chance it will hit the Earth in 2068. Getting as much information about it as soon as possible is crucial so that future generations will be prepared should its path eventually become a collision course.

Return of Axiom mission delayed again because of weather

Because of marginal winds at the splashdown points, SpaceX, Axiom, and NASA agreed today to delay the return of Axiom’s first private mission to ISS one more day.

The Axiom Mission 1 (Ax-1) crew is now targeting to undock from the International Space Station 8:55 p.m. EDT Sunday, April 23.

Weather permitting, the Ax-1 crew is targeted to close the hatch at about 6:45 p.m. Sunday, April 24, to begin the journey home in SpaceX Dragon Endeavour with splashdown off the coast of Florida approximately 1:00 p.m. Monday, April 25.

This delay will also delay the launch of NASA’s next crew to ISS on SpaceX’s new Dragon capsule, Freedom, now scheduled for launch no earlier than April 27th.

Astrobotics unveils nearly complete Peregrine lunar lander

Capitalism in space: Astrobotics yesterday unveiled its nearly complete Peregrine lunar lander, scheduled for launch later this year on the first launch of ULA’s new Vulcan rocket.

The lander is still being assembled, said John Thornton, chief executive of Astrobotic. Remaining work includes installation of its solar panels, two fuel tanks and decks holding payloads. The engines are “just about done,” he said, and will soon be installed.

He was optimistic that remaining work will be done quickly. “In just a couple months’ time, this will be heading out to environmental testing,” he said, followed by shipment to the launch site late this year.

This announcement now strongly suggests that Peregrine would not have been ready for Vulcan’s original launch date in late 2021. Since then the delays by Blue Origin in developing Vulcan’s first stage BE-4 engine has pushed the rocket’s first launch back by more than a year, time that apparently Astrobotics needed to finish Peregrine.

NASA awards contracts to six companies for its future orbital communications

Capitalism in space: NASA has awarded development contracts to six different companies to test the technology for providing the agency orbital communications for its manned missions, replacing the NASA-built TDRS satellite constellation.

In addition to SpaceX and Project Kuiper, the contractors include U.S.-based ventures representing Inmarsat, SES, Telesat and Viasat. Each venture will be required to complete technology development and in-space demonstrations by 2025 to prove that its system can deliver robust, reliable and cost-effective services — including the ability for new high-rate and high-capacity two-way links.

NASA would follow up by negotiating long-term contracts with multiple vendors to acquire services for near-Earth operations by 2030, while phasing out satellite communications systems owned and operated by the space agency.

Because NASA’s own station will likely be gone when these new in-space communications constellations become operational, their likely customers will not be NASA but the private space stations now under development. NASA is thus accepting responsibility for paying the cost for getting this communications need developed, for all the private companies. While the private space stations should eventually pay for using and building these constellations, it makes sense for NASA to get this started. No one company could likely afford or even be willing to pay the entire cost, and getting them all to work out an arrangement now would be difficult. NASA in turn can get it done now, and then later negotiate contracts with the private stations to pay for its construction and use.

SLS launch now definitely delayed until July, at the earliest

NASA yesterday admitted that with the decision to return SLS to the vehicle assembly building (VAB) before completing its dress rehearsal countdown, it is now impossible to launch SLS in the June launch window as planned, and that the earliest the rocket could launch would be July.

This summary of the issues that dogged the rocket during the three attempts to complete that dress rehearsal illustrates the likelihood that SLS has many engineering loose ends still unresolved:

On April 3 it was malfunctioning fans on the Mobile Launcher needed to clear hazardous fumes. On April 4, it was a defective helium check valve on the Interim Cryogenic Propulsion Stage, ICPS, the Space Launch System’s second stage. On April 14, it was a hydrogen leak on the SLS first stage, or Core Stage.

Once again, having such problems during the first countdown of a new rocket is not unusual. What is questionable is only finding them now, at the very end of the rocket’s development.

I predict the launch will be further delayed until the fall, at which time NASA might face a much more serious issue regarding SLS’s two strap-on solid rocket boosters. During the shuttle era NASA had always placed a one year limit on their use once they were stacked, because it was believed that standing in a vertical position for too long could warp and distort the solid rocket fuel, thus causing it to burn improperly during launch.

These boosters were first stacked near the end of 2020, so their use-by date should have been January 2022, at the latest. Not launching until the fall will place them nine to eleven months past that date. And since these boosters are taller than the one’s used by the shuttle, they are heavier which makes extending that lifespan even riskier.

Thus, if NASA decides it must replace the boosters, that will likely delay the launch another three to six months, pushing it into ’23 at the earliest. If NASA decides to go with these boosters, it poses a real risk of failure during launch, a failure that will certainly destroy the rocket.

NASA abandons 4th attempt to complete SLS dress rehearsal countdown

UPDATE: NASA today decided to scrub a fourth attempt to complete a full dress rehearsal countdown of its SLS rocket on April 21 later this week, and roll the rocket back to the vehicle assembly building (VAB).

NASA said that its contractors, as well as its agency’s, will use the next several weeks to address problems that cropped up during the fueling tests when the SLS rocket returns to the large Vehicle Assembly Building. For example, gaseous nitrogen system supplier Air Liquide will upgrade its capabilities. NASA will also replace a faulty check valve on the upper stage of the rocket, as well as fix a leak on the mobile launch tower’s “tail service mast umbilical,” a 10-meter-tall structure that provides propellant and electricity lines to the rocket on the pad.

This situation is increasingly becoming a big problem for NASA, and the SLS rocket. After returning it to the VAB it will take several weeks to address the issues that caused the aborts on the previous attempts. If the agency then repeats the wet dress rehearsal to make sure all is well and then returns the rocket again to the VAB, it would delay the actual launch to late summer or early fall. At that point the two strap-on solid rocket boosters will have been stacked almost two years, almost twice as long as they are supposed to before launch.

The agency could attempt to roll out the rocket for a dress rehearsal, and then proceed directly to launch. That would allow the possibility of a launch in the early summer, but for that plan to work everything must work perfectly.

The many problems during the dress rehearsal were in themselves not bad marks against the rocket or program. This was a test to iron out kinks in the launch procedures, and such issues should be expected. The real problem is that these kinks during launch countdown are being worked out now, at the very end of development, rather at the beginning. They suggest that the rocket has a lot of engineering loose ends that were not thoroughly tested and worked out in development, thus increasing the likelihood of a complete failure during actual launch.

This rocket was first conceived in 2004. Its development, in fits and starts, has now been on-going for 18 years. The total cost exceeds $30 billion (not including the $20 billion or so spent on the Orion capsule). That it is not ready to launch is a striking condemnation of our entire government. The rocket was designed by Congress, and NASA’s program to build it has been costly, slow, and poorly managed, from the beginning.

As I wrote in 2011, it should have been scrapped more than a decade ago, replaced with rockets from the private sector. Had our incompetent federal government done that we would likely be launching humans to the Moon, now, and saved a lot of money in the process.

Original post:
—————-
NASA has now scheduled for no earlier than April 21, 2022 its fourth attempt to complete a SLS dress rehearsal countdown, stymied the last time by a hydrogen fuel leak.

Each delay puts further pressure on the agency’s hope of launching in June. And each launch delay puts the rocket’s solid rocket boosters farther and farther past their use-by date that officially arrived in January.

Boeing and NASA set May 19th for second Starliner unmanned demo launch

NASA yesterday announced May 19th as the new launch date for Boeing’s second attempt to complete the first unmanned Starliner demo mission to ISS.

The uncrewed mission will test the end-to-end capabilities of the Starliner spacecraft and Atlas V rocket from launch to docking and return to Earth at one of five designated landing zones in the western United States. Following a successful completion of the OFT-2 mission, NASA and Boeing will determine a launch window for NASA’s Boeing Crew Flight Test (CFT), Starliner’s first flight with astronauts aboard.

The first unmanned demo flight in December 2019 failed to dock with ISS and had to be cut short due to serious software issues. The launch of the second unmanned demo flight was scrubbed mere hours before launch in August of 2021 due to serious valve issues.

Thus, Boeing’s manned capsule is more than two years behind schedule. Not only has Boeing had to pay more than $400 million for a second demo mission, the delays have caused a lot of business with NASA and with tourists to instead go to SpaceX. Hopefully, the company has finally fixed all issues and will succeed and begin manned operations later this year.

Third SLS dress rehearsal countdown scrubbed before completion

NASA engineers today scrubbed their third attempt to complete a dress rehearsal countdown of the agency’s giant SLS rocket when a leak was detected in a hydrogen fuel line.

The team will not conduct the terminal countdown activities today as planned and will assess next steps after today’s operations.

The problem appears to be “a leak … in the tail service mast umbilical.”

It is not clear yet how much of the countdown and fueling will be completed. Because of a faulty valve in the upper stage, NASA management had already decided to eliminate fueling of the rocket’s upper stage from the rehearsal. The problem today appears to involve the core first stage’s hydrogen tanks, which are presently partly filled only about 5%. Based on their last tweet, it appears they have not drained the tank, though they apparently will not continue the rehearsal today.

UPDATE: NASA just tweeted the following:

Teams have confirmed they have satisfied the test objectives for the ICPS [upper stage] LH2 [hydrogen tank] chilldown and after gathering additional data, will work to drain propellant from the rocket. They will inspect the TSMU umbilical connection, review data, and establish a go-forward plan.

This sounds as if the agency might decide they have completed enough of the dress rehearsal to consider it complete, and will now roll the rocket back to the vehicle assembly building for further check out.

NASA will not load fuels in SLS upper stage in next dress rehearsal countdown attempt

In the next attempt to complete the first “wet dress rehearsal” of NASA’s SLS rocket tomorrow, April 11th, the dress rehearsal will not be as wet as originally planned.

NASA said April 7 that engineers found a problem maintain helium purge pressure in the ICPS [SLS’s upper stage] after changing out a regulator in the mobile launch platform. At that time, the agency said it was able to restore normal pressure but was still studying the source of the problem, now linked to the faulty valve in the ICPS itself.

Because that issue, NASA now plans to limit the amount of liquid oxygen and liquid hydrogen propellant loaded into the ICPS during the WDR. NASA said the countdown rehearsal will be modified with “minimal propellant operations” on the ICPS, but didn’t elaborate on how much propellant would be transferred into the upper stage.

As usual, NASA officials are now making believe that they will achieve all their goals for the dress rehearsal if they complete it without completely fueling the upper stage. This is intellectually dishonest. This dress rehearsal was intended to test all aspects of the rocket’s launch countdown, including the fueling of all its stages. If they complete it without successfully fueling the upper stage, they will not achieve all their goals. Period.

The plan right now is to attempt this revised launch rehearsal tomorrow, then return the rocket to the vehicle assembly building where engineers will replace the faulty valve. At that point it is unclear what the agency will do next.

Though this incomplete test will have taught them a lot, if they do not redo the dress rehearsal with full loading of all stages but instead proceed to a launch attempt in the present target window from June 6 to June 16, they will be doing so with a greater risk. Of course, if the new valve works during that launch attempt, then all should be well. In fact, this risk appears quite reasonable.

Nonetheless, the fundamental problem remains: NASA is under pressure to launch, and held off this kind of testing until very late in the program. Finding these problems now puts serious limits on the ability of the agency to fix them. This in turn puts serious limits on the reliability of SLS.

Spinlaunch wins suborbital launch contract from NASA

Spinlaunch prototype suborbital launcher

Capitalism in space: Spinlaunch has won a launch contract from NASA to use its rocket-tossing spin launcher, shown in the photo to the right, to place a test payload on a suborbital flight later this year.

Unlike a vertical rocket first stage, the launcher spins its upper stage to a high acceleration and flings it upward. While the G-forces are too brutal for any delicate equipment or biology, this technique could be a very cheap way to toss bulk payloads like water and oxygen into space.

Spinlaunch has already done one test flight in November ’21, and hopes to do its first orbital test flight by ’25.

Inspector General: NASA’s lunar rover VIPER mission on schedule, with some cost increases

VIPER's planned route on the Moon

According to a report [pdf] issued today by NASA’s inspector general, the agency’s VIPER lunar rover mission is generally on schedule for its ’23 launch, though it has experienced some cost increases and still carries some scheduling risks, mostly related to the development of Astrobotic’s commercial Griffin lunar lander, and its precursor Peregrine mission that ULA hopes to launch on its first Vulcan rocket test.

Although Astrobotic personnel explained that Griffin’s development schedule is largely independent of its Peregrine mission, the Peregrine Lander—planned to launch in 2022—has multiple systems and subsystems that will also be used on Griffin. Therefore, any technical problems with these systems may adversely affect development of the Griffin Lander because Astrobotic would only have about a year, depending on the Peregrine launch date and start of lunar operations, to resolve the issues prior to NASA delivering VIPER for integration and launch. Furthermore, any failures during the Peregrine mission may lead to Griffin delays as NASA and Astrobotic investigate the failures and develop corrective actions.

In addition, VIPER long-lead acquisitions—such as the rover solar power array and avionics unit—have been affected by aerospace industry supply chain delays caused by COVID-19 as have delivery of computer boards and motor parts. Both of these issues have impacted design verification testing needed for the mission’s Critical Design Review, while COVID-19 also delayed some component development schedules.

Peregrine’s launch has been delayed by a year because Vulcan has been delayed because of Blue Origin’s problems with the BE-4 rocket engine. Though ULA hopes the Vulcan/Peregrine launch can occur late this year, that date remains very much in doubt. Further launch delays would thus threaten the launch of Griffin and VIPER.

As for the cost increases, the IG found that NASA had been forced to increase the budget for VIPER by 18.1%, a relatively minor increase compared to many of NASA’s other big projects. The IG noted however that further cost overruns are very possible, especially if the Peregrine mission experiences problems.

The photo above shows the rover’s presently planned route in the relatively flat area about 85 miles from the Moon’s south pole and near the western edge of Nobile Crater (pronounced No-BEEL-e).

NASA postpones next SLS dress rehearsal countdown attempt to next week

NASA officials today said that they have postponed their next attempt to complete the first dress rehearsal countdown of the SLS unitl next week, thus allowing the private commercial manned Axiom launch to ISS to proceed on April 8th.

The rocket will remain at the launch site as the engineering teams assess the issues that caused two scrubs and several launch count down holds.

SLS dress rehearsal countdown scrubbed an hour before T-0

Yesterday’s first dress rehearsal countdown for NASA’s SLS rocket managed to get within an hour of T-0 with its oxygen tanks half full when mission control scrubbed the countdown.

During chilldown of the lines in preparation for loading the liquid hydrogen, the teams encountered an issue with a panel on the mobile launcher that controls the core stage vent valve. The purpose of the vent valve is to relieve pressure from the core stage during tanking. Given the time to resolve the issue as teams were nearing the end of their shifts, the launch director made the call to stop the test for the day. A crew will investigate the issue at the pad, and the team will review range availability and the time needed to turn systems around before making a determination on the path forward.

No word as yet when they will attempt the next full dress rehearsal. The delays with SLS have so far caused several further delays for Axiom’s private mission to ISS, since NASA has given SLS priority over the range. It has now been pushed back to April 8th.

Note that none of these problems should be a surprise. This is the first time the rocket and mobile launcher have been placed under flight conditions, so minor issues should be expected. At the same time, dealing with these issues now, just before actual launch, rather than earlier in development, illustrates the backwards way NASA’s management has run this program. You can never design anything new perfectly. You need to test and fail and fix along the way. NASA avoids testing because it can’t build anything at a reasonable cost. The result is that when it comes time to launch, lots of previously unidentified minor issues pop up that need fixing.

NASA aborts fueling in SLS dress rehearsal countdown

UPDATE: Dress rehearsal countdown to resume, now aiming for a 2:40 pm (Eastern) T-0 tomorrow, April 4th.

NASA announced this morning that it has aborted fueling in SLS dress rehearsal countdown because of a problem with the rocket’s mobile launcher.

Teams have decided to scrub tanking operations for the wet dress rehearsal due to loss of ability to pressurize the mobile launcher. The fans are needed to provide positive pressure to the enclosed areas within the mobile launcher and keep out hazardous gases. Technicians are unable to safely proceed with loading the propellants into the rocket’s core stage and interim cryogenic propulsion stage without this capability.

It appears engineers are assessing the issue and hope to resume the countdown so as to proceed with rocket fueling tomorrow.

SLS dress rehearsal begins, with press coverage limited by NASA

NASA today began the two-day-long “wet dress rehearsal” countdown of its first SLS rocket, with T-0 expected to occur at 2:40 pm (Eastern) on April 3rd.

The article at the link provides all the information you could want about this rocket, which is now about seven years behind schedule and having a cost so far about $25 billion. This quote however tells us much about the mentality at NASA:

But much of the test will happen without independent press coverage. NASA plans to provide sanctioned updates on the two-day dress rehearsal via the agency’s website and social media accounts, but news media representatives are not being permitted to listen to the countdown activities.

NASA has cited security and export control restrictions for the move. Numerous media representatives requested access to the SLS countdown audio for the wet dress rehearsal. Launch countdown audio feeds for other U.S. rockets, including those developed by private companies and hauling sensitive U.S. military satellites into orbit, are widely available to the news media and the public.

…NASA plans to release only text updates through the weekend. NASA TV will not be airing any live commentary for the final hours of the practice countdown. The agency’s television channel has previously provided live coverage of similar events, such as space shuttle tanking tests. [emphasis mine]

NASA reasons for not allowing anyone to listen to its audio feed — “security and export control restrictions” — is an utter lie. The real reason is that NASA fears the public’s reaction should anything not go exactly as planned. By blocking access to the audio feed, they can hide any faux pas.

NASA’s fear of course is misplaced. This is a test. No one will be surprised or outraged if it doesn’t go perfectly. Better to be open and up front than try to hide problems, because eventually those problems will be revealed and the cover-up will do far more harm to NASA’s reputation than the problems themselves.

The many new private rocket companies, SpaceX, Rocket Lab, Astra, Virgin Orbit, understand this, which is why they all make their primary countdown audio feeds available, though of course they almost certainly have secondary private feeds where engineers can speak more freely. Similarly, NASA did the same in the 1960s, and then during the entire shuttle program.

Now however “export control restrictions” and “security” requires them to be secretive? It is to laugh.

Soyuz capsule returns three astronauts safely, completing Mark Vande Hei’s 355 day mission

A Russian Soyuz capsule successfully returned three astronauts back to Earth today, thus completing Mark Vande Hei’s 355 day mission, the longest so far achieved by an American astronaut.

Vande Hei’s record is the fifth longest overall, behind four other Russians on Mir. Musa Manarov and Vladimir Titov were the first to complete a year-long flight in 1987-1988. Sergei Avdeyev’s flight of 381 days on Mir in 1998-1999 is the second longest. Valery Polyakov holds the record for the longest flight, 437 days in 1994-1995.

Now that Vande Hei is safely back on Earth, expect Dmitry Rogozin, the head of Roscosmos, to make some announcement in the next day or so further limiting cooperation at ISS. It is my expectation he will end the discussions between Roscosmos and NASA to exchange one-for-one flights on each other’s capsules. While the partnership to maintain and occupy ISS will continue, Rogozin will likely end any cooperation otherwise.

Surprise! NASA’s ’23 budget request asks for more money!

In releasing its budget request this week to Congress for the 2023 fiscal year, NASA did what it routinely does each year, ask for more money, this time asking for an 8% increase from what Congress appropriated last year.

NASA’s FY2023 budget request is $25.974 billion versus the FY2022 appropriation of $24.041 billion. NASA had requested $24.802 billion in large part to pay for the Artemis program to return astronauts to the lunar surface, but Congress wasn’t willing to allocate that much. While supportive of Artemis and NASA’s many other science, aeronautics and technology programs, there is a limit as to how much Congress is willing to invest.

NASA is requesting not just another boost in FY2023, but in the “out years” thereafter, rising to $28 billion in FY2027, though much of that purchasing power likely will be lost to inflation.

…In essence, the agency wants more money for everything it is doing.

The budget request also asks again for Congress to terminate the SOFIA airborne telescope, which NASA contends is not producing enough science to justify its $80 million annual cost. Congress has repeatedly refused to do so in past years. As should be expected, Congress will likely not cancel SOFIA again, as it likes to spend money we don’t have.

The goal of the increased funding for Artemis is also to continue the SLS program for many years to come. Expect Congress to also fund this in the coming few years, though the long term future of SLS remains in doubt, especially if SpaceX’s Starship begins flying. Artemis won’t be cancelled by our spendthrift Congress, but Congress will likely decide to shift that spending to Starship and other private rockets rather than SLS as those private rockets come on line.

All in all, expect Congress to give NASA more cash, but not as much as the agency requests.

Biden administration demands that all NASA grantees hire minorities/women

“Segregation today, segregation tomorrow, segregation forever!” The Biden administration has proposed a new rule for anyone receiving financial grants from NASA, requiring those grantees to solicit bids for any subcontracting work from minorities and/or women.

The Grants Policy and Compliance Branch (GPC) in the National Aeronautics and Space Administration’s (NASA) Office of the Chief Financial Officer is soliciting public comment on the Agency’s proposed implementation of a new term and condition that requires recipients of NASA financial assistance to obtain a quotation from small and/or minority businesses, women’s business enterprises or labor surplus area firms when the acquisition of goods or services exceeds the simplified acquisition threshold.

…NASA’s expectation is that this action will result in an increase in contracting opportunities for small and/or minority businesses, women’s business enterprises and labor surplus area firms that contract with NASA financial assistance recipients.

The rule is not yet in effect. NASA is simply seeking public comment. However, the intent of this “equity” regulation is the same as all critical race theory implementations, to favor minorities and women and discriminate against whites and men. And if you don’t believe me, read this further explanation for this new rule at the link:

On January 25, 2021, President Biden issued E.O. 13985, “Advancing Racial Equity and Support for Underserved Communities Through the Federal Government,” outlining a comprehensive approach to advancing equity for all, including people of color and others who have been historically underserved, marginalized, and adversely affected by persistent poverty and inequality. Given that advancing equity requires a systematic approach to embedding fairness in the decision-making process, the E.O. instructs agencies to recognize and work to redress inequities in their policies and programs that serve as barriers to equal opportunity.

Since everyone has the same equal opportunity to compete for bids, this new Biden rule, which is designed to tilt the scale and discriminate in favor of “people of color and others who have been historically underserved”, it is actually creating barriers to equal opportunity. It is also a bald-faced violation of every civil rights law passed since 1964, which required that no one should be discriminated against because of their race, ethnicity, religion, or sex, be they white, black, red, yellow, green, or orange.

But then, this is our Democratic Party, led by Joe Biden. It has eagerly returned to its slave/segregation roots, where it sees race as a person’s only important attribute, with some races deserving favored treatment and other races to be oppressed. Until the civil rights movement of the 1950s and 1960s Democrats favored whites and oppressed minorities. Now the party favors minorities and oppresses whites.

Nothing has really changed however. The Democratic Party, led by Joe Biden, remains the party of racism and bigotry.

NASA solicits proposals for second commercial manned lunar lander

Having received a budget boost from Congress for its manned lunar lander Artemis program, NASA yesterday announced that it is soliciting proposals from the private sector for a second lunar lander, so that the agency will not be reliant only on SpaceX’s Starship.

To bring a second entrant to market for the development of a lunar lander in parallel with SpaceX, NASA will issue a draft solicitation in the coming weeks. This upcoming activity will lay out requirements for a future development and demonstration lunar landing capability to take astronauts between orbit and the surface of the Moon. This effort is meant to maximize NASA’s support for competition and provides redundancy in services to help ensure NASA’s ability to transport astronauts to the lunar surface.

As part of this revised program, NASA also is negotiating a revision to its contract with SpaceX. It appears that this change will have SpaceX fly an additional manned mission with Starship, after which NASA would open up competition to everyone on future flights. The press release however is not entirely clear on this point.

This new competition will of course be a boon to the losers in the first manned lunar lander competition, Blue Origin and Dynetics. Both will certainly submit bids, as will others.

NASA: Europa Clipper’s cost rise; Mars sample return delayed

At a meeting this week NASA officials admitted that the cost of its Europa Clipper mission has risen by three quarters of a billion dollars, and that the sample return mission to bring back Perseverance’s core samples will be delayed, as well as now require two landers, not one.

NASA revealed significant changes to two of its flagship planetary science missions at today’s Space Science Week meeting at the National Academies of Sciences, Engineering and Medicine. The cost for Europa Clipper, which will gather data as it makes multiple swingbys of Jupiter’s moon Europa, has grown from $4.25 billion to $5 billion. Separately, NASA and ESA are replanning the Mars Sample Return mission. Two landers are needed instead of one to retrieve samples from the surface of Mars and boost them into orbit for their trip back to Earth. The launches will be in 2028 instead of 2026.

The sample return mission itself is also growing in complexity:

A Sample Fetch Rover will be sent to collect them and take them to a Mars Ascent Vehicle — a rocket — that will shoot them into Martian orbit where they will be transferred to an Earth Return Orbiter for the trip back to Earth.

Initially the plan was for the fetch rover and ascent vehicle to be launched together in 2026, and the Earth Return Orbiter in 2027. But Zurbuchen decided to convene an Independent Review Board in 2020 to get an impartial assessment of the plan by outside experts. The Board cautioned that 2026 was “not achieveable” with 2028 a more realistic date, and that the “program’s schedule and cost are not aligned with its scope.”

Consequently, NASA now has replanned the mission with two landers — one each for the fetch rover and ascent vehicle — instead of one. Both landers will launch in 2028. The Earth Return Orbiter will still launch in 2027. The samples will get back to Earth in 2033.

Prediction: The launch of this fleet of sample return spacecraft will be further delayed, and its overall cost will rise, by a lot. In fact, it is very possible that SpaceX’s Starship will have already returned samples from Mars before NASA’s mission gets off the ground.
