ULA begins stacking Atlas-5 rocket for launching the first manned mission of Starliner

9:26 am

ULA has begun to assemble the Atlas-5 rocket that will hopefully launch Boeing’s Starliner capsule on its first manned mission to ISS, presently targeting a late April lift-off.

The rocket’s main stage was transferred from the nearby Advanced Spaceflight Operations Center to the integration facility Wednesday, Feb. 21, where it will await integration with the rocket’s upper Centaur stage and Starliner. The spacecraft will carry NASA astronauts Suni Williams and Butch Wilmore to the orbiting laboratory for a short stay of about one to two weeks before returning to a landing site in the southwest United States.

The late April date appears to be a slight delay from previous announcements.

Odysseus’ tip-over likely caused because it landed without good elevation data

9:08 am

It appears that the improvised switch to a NASA range finder instrument just before landing only partly worked during Odysseus’s landing attempt on the Moon, causing the spacecraft to hit the ground at too great a speed with too much laterial motion, resulting in the snapping of one leg and the lander tipping over.

Apparently, Odysseus could no longer process altitude data from the NASA instrument once it was within 15 kilometers of the surface. It had to rely on its optical cameras, a poor substitute.

By comparing imagery data frame by frame, the flight computer could determine how fast it was moving relative to the lunar surface. Knowing its initial velocity and altitude prior to initiating powered descent and using data from the inertial measurement unit (IMU) on board Odysseus, it could get a rough idea of altitude. But that only went so far. “So we’re coming down to our landing site with no altimeter,” Altemus said.

Unfortunately, as it neared the lunar surface, the lander believed it was about 100 meters higher relative to the Moon than it actually was. So instead of touching down with a vertical velocity of just 1 meter per second and no lateral movement, Odysseus was coming down three times faster and with a lateral speed of 2 meters per second.

Though the spacecraft landed upright, the high speed and sideways motion caused one leg to snap, and the spacecraft then fell over. In this sideways position Odysseus’ main solar panel could not get enough sunlight, forcing the mission to end prematurely.

A final press conference summing up the mission is scheduled for 2 pm (Eastern) today.

Was the mission a success? The failures and problems during touchdown illustrated engineering and management issues that must be addressed before the next flight. At the same time, the mission’s number one goal was to soft land on the Moon, and it did do so, even with those serious engineering problems.

More important, this flight’s first and foremost goal was an engineering test of that technology. In this sense that mission succeeded brilliantly, revealing those last technical issues.

NASA high altitude science balloon sets new endurance record

9:57 am

GUSTO's flight path
Click for continuous tracking of GUSTO’s flight path

NASA’s GUSTO high altitude science balloon has now set a new endurance record for the most days of flight of a NASA balloon, flying more than 57 days over the continent of Antarctica at the south pole.

The map to the right shows GUSTO’s entire journey. The blue line was its first phrase of travel, the green its second phase, and the red its present stage.

GUSTO was launched at 1:30 a.m. EST Dec. 31 from the Long Duration Balloon Camp near McMurdo Station, Antarctica. The balloon mission not only broke the flight record but continues its path circumnavigating the South Pole. The stadium-sized zero-pressure scientific balloon and observatory are currently reaching altitudes above 125,000 feet. “The health of the balloon and the stratospheric winds are both contributing to the success of the mission so far,” said Hamilton. “The balloon and balloon systems have been performing beautifully, and we’re seeing no degradation in the performance of the balloon. The winds in the stratosphere have been very favorable and have provided stable conditions for extended flight.”

The previous NASA record was a balloon that it flew in 2012. GUSTO itself is being used to map the Milky Way’s carbon, oxygen, and nitrogen that is found between the stars in gas clouds.

Odysseus is on its side, some antennas blocked

11:30 pm

It appears the reason communications with Intuitive Machines’ Odysseus lunar lander has been so difficult since its landing yesterdary is that something caused it to fall over so that it is now lying on its side, blocking some of its antennas.

Intuitive Machines initially believed its six-footed lander, Odysseus, was upright after Thursday’s touchdown. But CEO Steve Altemus said Friday the craft “caught a foot in the surface,” falling onto its side and, quite possibly, leaning against a rock. He said it was coming in too fast and may have snapped a leg. “So far, we have quite a bit of operational capability even though we’re tipped over,” he told reporters.

But some antennas were pointed toward the surface, limiting flight controllers’ ability to get data down, Altemus said. The antennas were stationed high on the 14-foot (4.3-meter) lander to facilitate communications at the hilly, cratered and shadowed south polar region.

Its exact location also appears to be several miles from its intended landing site next to the crater Malapart A. Scientists who operate Lunar Reconnaissance Orbiter (LRO) hope orbital images this weekend will identify the spacecraft’s precise location.

The company also revealed that the reason its own laser guidance system would not function — requiring a quick software patch allowing the spacecraft to use a different NASA system — was because “a switch was not flipped before flight.”

Because of this switch in navigation equipment it was decided to cancel the release of the student-built camera probe dubbed Eaglecam that was supposed to be released when Odysseus was about 100 feet above the surface and take images of the landing. Instead, it is now hoped it can be released post landing and get far enough away to look back and capture photos of the lander.

All these problems however do not make this mission a failure. Like Japan’s SLIM lander, the primary goal of this mission was to demonstrate the technology for softlanding an unmanned spacecraft on the Moon. Intuitive Machines has succeeded in this goal. Though obviously some changes must be made to improve this engineering, the success with Odysseus strongly suggests the next mission later this year will do far better.

Vast to compete with Axiom for NASA’s limited slots for commercial manned missions to ISS

9:40 am

The private space station company Vast, the only one presently building its own space station without a NASA contract, has now announced that it intends to to compete with Axiom for the limited docking slots NASA has made available for commercial manned tourist missions to ISS.

During a panel discussion at the Federal Aviation Administration Commercial Space Transportation Conference Feb. 21, Max Haot, chief executive of Vast, said his company would bid on the fifth and sixth private astronaut missions, or PAMs, that NASA offers to companies seeking to flying commercial missions to the ISS. “From our point of view, it will make us a better space station builder, a better partner of NASA, and it will help us practice a lot of the disciplines we are building” for its future commercial stations, he said of Vast’s plan to bid on the missions.

Up until now, Axiom has had no competition for those limited docking opportunities, has flown two missions, with a third planned for this fall. All it needed to do is negotiate the rental fees with NASA for using ISS. Now NASA will need to open up bidding for those slots. Its job is not to play favorites, but to instead make its taxpayer-funded facilities available to as many private companies as possible. Whether it will do so is at present unclear.

Vast’s own space station, a single module to be launched on SpaceX’s Starship/Superheavy, dubbed Haven-1, is scheduled for launch next year according to Vast officials. If so (assuming SpaceX’s rocket is operational by then), Vast will be the first private space station in orbit, beating Axiom and the two consortiums building Orbital Reef and Starlab. And it will have done it without taxpayer money.

Live stream of landing of Odysseus on Moon

8:59 am

South Pole of Moon with landing sites

UPDATE: The engineering team has decided to delay the landing attempt by one lunar orbit, pushing it back to 6:24 pm (Eastern). The live stream begins well before then, so that NASA can get in a lot of blather and propaganda, so feel safe waiting to tune in until 6 pm (Eastern).
——————-
Capitalism in space: I have embedded below the NASA live stream for the presently scheduled 5:30 pm (Eastern) landing on the Moon of Intuitive Machines Nova-C lunar lander dubbed Odysseus.

The green dot on the map to the right marks the planned landing site, about 190 miles from the Moon’s south pole. This will be the closest attempted landing so far to that pole, and if successful it will land on the rim of a crater, Malapart A, that is believed to have a permanently shadowed interior.

Odysseus however has no instruments capable of seeing into that interior. Its main mission is engineering, to test the landing technology of Intuitive Machines’ spacecraft. As part of this effort, it will release a small camera probe, dubbed EagleCam, when it is about 100 feet above the surface, which will to take images of that landing. [Update: That probe is unprecedented for another reason: It will be first student-built probe to land on another world, as it was designed and built by a team of students at Embry-Riddle Aeronautical University in Florida.]

If the landing is successful, Odysseus is designed to last until sunset on the Moon, about another two weeks. It carries a variety of NASA and commercial payloads, including a private small optical telescope. More important, it will allow the company to follow through with its manifest of future missions, including a second lunar landing later this year.

Tomorrow’s landing of Intuitive Machine’s Odysseus lunar lander

9:26 am

South Pole of Moon with landing sites
Nova-C is Odysseus’s landing spot

NASA has now announced its planned live stream coverage of tomorrow’s landing attempt of Intuitive Machine’s Odysseus lunar lander near the south pole of the Moon.

Intuitive Machines is targeting no earlier than 5:49 p.m. EST Thursday, Feb. 22, to land their Odysseus lunar lander near Malapert A in the South Pole region of the Moon.

Live landing coverage will air on NASA+, NASA Television, the NASA app, and the agency’s website. NASA TV can be streamed on a variety of platforms, including social media. Coverage will include live streaming and blog updates beginning 4:15 p.m., as the landing milestones occur. Upon successful landing, Intuitive Machines and NASA will host a news conference to discuss the mission and science opportunities that lie ahead as the company begins lunar surface operations.

No live stream is of course active yet. When it goes live tomorrow afternoon I will embed the youtube broadcast here on Behind the Black.

If successful, Odysseus will be the first American landing on the Moon since the manned Apollo missions more than a half century ago. It will also mark the first successful lunar landing achieved by a privately-built spacecraft. Companies from Israel, Japan, and the U.S. have already tried and failed.

SpaceX successfully launches Intuitive Machines Odysseus lunar lander

11:20 pm

South Pole of Moon with landing sites

SpaceX has successfully launched Intuitive Machines commercial Nova-C-class Odysseus lunar lander, its Falcon 9 rocket lifting off from Cape Canaveral at 1:05 am (Eastern) on February 15th.

This was the third launch in less than eleven hours today, and the second launch by SpaceX. The first stage successfully completed its 18th flight, landing back at Cape Canaveral.

The green dot on the map to the right shows the planned landing site for Odysseus, next to a crater with a permanently shadowed interior, though it will have no way to travel into it. This will also be the closest landing to the Moon’s south pole, and if all goes well, will take place eight days from today, where it will operate for about ten Earth days. You can find out more about the lander’s payloads and mission from the press kit [pdf].

It must be emphasized that like India’s Vikram lander and Pragyan rover, Japan’s SLIM lander, and Astrobotic’s Peregrine lander, Odysseus is mostly an engineering test to prove out the landing systems. If this spacecraft does any science on the lunar surface that will be a bonus.

The leaders in the 2024 launch race:

14 SpaceX
8 China
2 Iran
2 Russia

American private enterprise now leads the entire world combined 16 to 14 in successful launches, with SpaceX by itself is now tied the rest of the world combined (excluding American companies) 14 to 14.

JPL to lay off 8% of its work force plus 40 contractors

11:34 pm

Claiming the uncertainty of its federal budget allocation due to Congress’s inability to pass a new budget, the Jet Propulsion Lab (JPL) earlier today announced it was laying off 8% of its work force, 530 employees, plus 40 contractors.

In a memo to JPL staff Feb. 6, [director Laurie] Leshin said that a lack of a final 2024 appropriations bill — NASA is operating on a CR [continuing resolution] that runs until March 8 — forced the layoffs after taking other measures such as a hiring freeze and reductions in MSR [Mars Sample Return] contracts and other spending, as well as the earlier contractor layoffs. “So in the absence of an appropriation, and as much as we wish we didn’t need to take this action, we must now move forward to protect against even deeper cuts later were we to wait,” she wrote.

Uncertainty about how the Mars Sample Return project should be designed and built had caused Congress to express doubts about the project, with the Senate suggesting major cuts. NASA responded by loudly pausing the project and suggesting its own cuts. JPL has now followed up with these layoffs. Both have I think done so as a lobbying tactic, and as expected in this game of budget lobbying these actions have caused many legislators to scream in horror: “We really didn’t mean it! We really don’t want to cut anything!”

Expect our bankrupt Congress to fold and provide NASA and JPL the blank check it wants to fly a Mars mission that will cost billions, be years late, and likely be beaten to Mars by SpaceX’s Starship (which could do the job for a tenth the cost).

Collins Aerospace tests its new spacesuit on the Zero Gravity airplane

9:37 am

On January 30, 2024 Collins Aerospace, one of two companies that NASA has contracted to design and build new spacesuits for its future missions, successfully tested its new spacesuit on the Zero Gravity airplane, where it was able to have a person use the suit in short but weightless conditions.

Collins is designing its suit in collaboration with ILC Dover and Oceaneering. Former NASA astronauts, John “Danny” Olivas and Dan Burbank, each donned the suit and performed a series of test objectives while onboard a Zero Gravity plane that’s able to perform parabolic maneuvers to simulate microgravity for short bursts. They were surrounded by several support personnel who were gathering data about the suit performance.

In total, they performed 40 parabolas during the flight. Collins said the primary goals included “evaluation of the suit’s pressure garment system fit and functionality, use of International Space Station tools and interfaces, and reviewed performance of the new Extravehicular Mobility Unit, or EMU, against the current design.”

The two spacesuit contracts (the second is with Axiom) are costing NASA about $335 million total to get the suits designed, built, and certified for use in spacewalks and ground operations on the Moon. Both companies appear on schedule to deliver those suits in less than three years.

Previously, NASA had tried to build new spacesuits on its own, and had spent a billion dollars over fourteen years while building nothing. The contrast in this story between the government and private enterprise should be clarifying to everyone.

Northrop Grumman writes off $100 million on its fixed-price Lunar Gateway contract

10:00 am

Northrop Grumman announced on January 25, 2024 that it has written off another $42 million on its fixed-price contract with NASA to build the main habitable module for its Lunar Gateway space station, bringing the total losses so far to $100 million.

The company blamed the latest charge primarily on “cost growth stemming from evolving Lunar Gateway architecture and mission requirements combined with macroeconomic challenges.” The company offered the same explanation when it reported the charge in the second quarter.

Northrop received a $935 million fixed-price contract from NASA in July 2021 to build the module, which is based on the company’s Cygnus cargo spacecraft. HALO will provide initial living accommodations on the Gateway and includes several docking ports for visiting Orion spacecraft and lunar landers as well as additional modules provided by international partners. It will launch together with the Maxar-built Power and Propulsion Element (PPE) on a Falcon Heavy.

In a fixed price contract NASA is not suppose to issue change orders. What must be happening is that either the company or NASA are recognizing there are some issues with the initial and then revised designs, forcing Northrop Grumman to issue its own change orders, delaying development and adding costs.

That the company is having problems however is a bit baffling. First, space station module design is not new. There is a history going back decades on how to do this. Second, Northrop is basing this module design on its already launched Cygnus freighters. Though unmanned, these freighters still have to be habitable after docking with ISS. It should not be so difficult to upgrade them.

Regardless, the company has now become hostile to bidding on any future fixed price contracts, or if it does, it will bid much higher (a decision that caused it to lose in another recent bidding contest). Hopefully this decision on fixed price contracts, similar to Boeing’s own decision, will not cause NASA to abandon such contracts. Just because these big, old-space companies can’t work efficiently doesn’t mean others can’t. Fixed-price is how every business in the real world must function. For most NASA projects such a deal is realistic. If these old companies can’t function practically let new companies bid instead. This will be better for NASA and the entire American space industry.

Ingenuity’s mission on Mars is over

3:55 pm

Ingenuity takes off!
Ingenuity takes off on its first flight, April 19, 2021.
For full images go here and here.

NASA today announced that Ingenuity’s mission on Mars has now ended due to damage sustained to one of its propellers during its 72nd flight.

While the helicopter remains upright and in communication with ground controllers, imagery of its Jan. 18 flight sent to Earth this week indicates one or more of its rotor blades sustained damage during landing, and it is no longer capable of flight.

Ingenuity’s engineering mission was designed initially to simply prove that air-powered flight in Mars’ thin atmosphere was possible by a test program of four flights over 30 days. It worked so well that it just kept going and going. During its almost three years of operation on Mars, the helicopter completed 72 flights, for a total air time of about 128 minuntes. It flew a total of about eleven miles, reaching a maximum speed of over 22 miles per hour and a top altitude of about 79 feet. On its 69th flight it traveled a record 2,315 feet, almost a half mile.

All future Mars missions have been changed forever by the success of Ingenuity and its designers and engineers. For example, there are already hints of a helicopter mission to Mars’ giant canyon Valles Marineris. In addition, NASA redesigned its Mars Sample Return Mission to include helicopters based on what it learned from Ingenuity.

More important, Ingenuity suggests that when settlers finally colonize the red planet, it is very possible that air travel will start out more important than ground transport. In fact, long distance roads might never be built, for any number of reasons, because air travel will be available from the beginning.

Starliner launch in mid-April continues on target

10:35 am

In an update today from NASA, it appears the first manned flight of Boeing’s manned Starliner capsule remains on target for a mid-April launch on a ULA Atlas-5 rocket.

Engineers continue to analyze the data from the recent parachute drop test that appeared to prove out the redesign of the capsule’s parachutes. Also, the work to replace or mitigate the flammable tape in the capsule has been completed.

Boeing completed removal of P213 tape that may have posed a flammability risk in certain environmental conditions. Boeing removed more than 17 pounds, or roughly 4,300 feet, of the material from the Starliner crew module. For areas in which removal of the tape carried an increased risk to Starliner hardware, Boeing applied tested remediation techniques such as overwrapping the P213 tape with another non-flammable, chafe-resistant tape, and installing fire breaks on wire harnesses.

No explanation as yet has been released as to how it was even possible for Boeing to have used this tape, considering it has been common practice since the Apollo 1 fire in 1967 to avoid the use of flammable materials in spacecraft. Nor has any explanation been issued on how the weak link in the main parachute connection to the capsule was not discovered until only weeks before the manned flight, last summer.

Nonetheless, both issues appear solved. After years of delays and innumerable problems, Boeing might finally be ready to fly Starliner with passengers. It desperately needs this flight to be successful, especially considering the company’s other ongoing problems with its 737 airplane. It also will not receive the rest of its contract payments from NASA until this flight is a success, and the delays and problems have cost the company more than $1.5 billion. The contract was fixed price, so Boeing has had to pay for all the additional costs from its own pocket.

Astrobotic’s Peregrine burns up in Earth’s atmosphere

8:23 am

At about 3:50 pm (Eastern) yesterday, the lunar lander Peregrine, built by the private company Astrobotic, hit the Earth’s atmosphere above the South Pacific and burned up, according to an update from the company.

The mission is over, having failed to reach the Moon due to a ruptured propellant tank caused by a leak in an interior helium tank.

The company was successful in regaining control over the mission after the leak, activating all payloads and getting data back from them, including images and even a short movie. It was also able to communicate with it from lunar distances. It failed however in testing its landing capabilities, its primary mission.

Next manned mission to ISS to launch tomorrow

10:12 am

The next manned mission to ISS, a private mission by the company Axiom carrying three European astronauts and commanded by an Axiom astronaut, is presently scheduled to launch tomorrow, January 18, 2024, at 4:49 pm (Eastern).

This is a private mission by Axiom, launched on SpaceX’s Falcon 9 and flying the astronauts in its Freedom Dragon manned capsule. This will be Freedom’s third flight to ISS. The launch was originally scheduled for today, but SpaceX scrubbed the mission today in order to give it “additional time allows teams to complete pre-launch checkouts and data analysis on the vehicle.” It appears during normal prelaunch checkouts engineers found the joints between the upper stage and the capsule were not tightened the proper amount. The company decided to replace the joints, which caused this one day delay.

The crew will spend up to fourteen days at ISS.

I have embedded a live stream of the launch below.

Boeing completes Starliner parachute drop test

9:13 am

Boeing on January 9, 2023 successfully completed a parachute drop test of its Starliner capsule, testing whether the redesigned connection between the chutes and the capsule was now meeting proper safety specifications.

The drop test, which used a Starliner parachute system attached to a dart-shaped sled the same weight as a Starliner, was performed to confirm the functioning of a redesigned and strengthened soft link joint that is part of the network of lines connecting the parachutes to the spacecraft. The test also validated a change to strengthen one textile joint in the parachute, increasing overall parachute robustness. As with other capsules, Starliner relies on parachutes to land safely when it returns to Earth.

Engineers are still analyzing the results, though the parachutes worked as planned. The first manned mission of Boeing’s commercial capsule is now scheduled for April 2024, only four years late as well as four years after SpaceX accomplished the same thing. It still remains staggering that the company did not find out about that soft link joint when it was designing the capsule, instead of only months before the first manned mission last year. It is not as if the use of parachutes to land capsules is cutting edge technology.

Peregrine only has hours left, its fuel leaking away

10:02 am

According to a number of recent updates by Astrobotic, its Peregrine lunar lander only only a few more hours of life left, its fuel leaking away due to the failure of a valve to close inside its oxygen tank.

Astrobotic’s current hypothesis about the Peregrine spacecraft’s propulsion anomaly is that a valve between the helium pressurant and the oxidizer failed to reseal after actuation during initialization. This led to a rush of high pressure helium that spiked the pressure in the oxidizer tank beyond its operating limit and subsequently ruptured the tank.

The company also noted that the Vulcan rocket did no harm to the spacecraft during launch, placing it in the correct orbit. The tank rupture however means it will not land on the Moon, and in fact is likely not going to escape Earth orbit. Sometime in the next day or so the spacecraft will run out of fuel, and at that point it will be fly out of control, its batteries draining because the solar panels will no longer point to the Sun.

How this failure will impact Astrobotic’s next and larger lander, Griffin, remains unknown. It is presently scheduled to land on the Moon in November 2024.

SpaceX: Ready to launch Starship/Superheavy by end of January but it won’t

9:28 am

Surprise! During the NASA press update yesterday making official the new delays in its entire Artemis lunar program, a SpaceX official revealed that the company will be ready to launch the third orbital test flight of its Starship/Superheavy rocket by end of January, but it also does not expect to get a launch approval from the FAA for at least another month.

Speaking during the press conference, SpaceX Vice President of Customer Operations & Integration Jensen said Starship hopes to be ready to test Starship once more by the end of January and to receive the necessary license from federal authorities to do so by the end of February.

During the conference Jensen made it repeatedly clear that it will require numerous further launch tests to get ready ready for its lunar landing mission for NASA — about ten — and that the company hopes to have this task completed by 2025 so that the agency’s new delayed schedule can go forward as now planned.

Yet how will SpaceX do this if the FAA is going to delay each launch because of red-tape by at least one month? SpaceX might be confident the FAA will give the okay for a launch in late February, but no one should be sanguine about this belief. Bureaucrats when required to dot every “i” and cross every “t”, as it appears the Biden administration is demanding, can be infuriatingly slow in doing so, even if they wish to hurry.

This news confirms my prediction from November that the launch will happen in the February to April time frame. It also leaves me entirely confident that my refined December prediction of a launch no earlier than March will be right.

SpaceX wants to do about six test launches per year. I don’t know how it can do so with the FAA holding it back.

NASA makes it official: The entire Artemis schedule is delayed

9:17 am

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

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

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

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

More details about the press briefing can be found here.

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

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

JPL lays off 100 contractors due to expected budget cuts

9:45 am

JPL last week laid off 100 contractors due to expected budget cuts in its troubled Mars Sample Return (MSR) mission.

A JPL spokesperson confirmed Jan. 7 that the center laid off the contractors and took other measures, such as across-the-board spending cuts and pausing work on one aspect of MSR, because of the “uncertain federal budget” in fiscal year 2024. The Los Angeles Times first reported the layoffs.

NASA announced in November that it would slow down work on MSR because of sharp differences in proposed funding for the effort in separate House and Senate bills. A House appropriations bill would provide the agency’s full request of $949.3 million while the Senate version allocated only $300 million.

Since the final budget has not been determined, nor has NASA made any decisions on what will happen to the sample return mission, these cuts (as well as NASA’s slowdown in November) are as much a political act as anything. JPL and NASA are trying to pressure Congress to fully fund everything, and by imposing cuts now the agencies generate news that elected officials don’t like. Routinely the legislators then back off of any budget cuts.

We shall see. Congress remains bankrupt, treating its budget as a blank check with money that grows on trees. Yet the sample return mission as presently designed is a mess. It needs a major reshaping in every way.

Astrobotic’s Peregrine lunar lander suffers major failure

12:10 pm

According to updates by the engineering team running Astrobotic’s Peregrine lunar lander, launched early today by ULA’s Vulcan rocket, the lander’s propulsion system suffered a major failure shortly after activation.

After successfully separating from United Launch Alliance’s Vulcan rocket, Astrobotic’s Peregrine lunar lander began receiving telemetry via the NASA Deep Space Network. Astrobotic-built avionics systems, including the primary command and data handling unit, as well as the thermal, propulsion, and power controllers, all powered on and performed as expected. After successful propulsion systems activation, Peregrine entered a safe operational state. Unfortunately, an anomaly then occurred, which prevented Astrobotic from achieving a stable sun-pointing orientation.

The company later released an update, stating that the failure caused “a critical loss of propellant” that will make the mission impossible as planned. They are reassessing to see if they can come up with an alternate plan, but without sufficient fuel no lunar landing will be possible under any mission profile.

Peregrine is a smaller test version of Astrobotic’s larger Griffin lunar lander, which has contracts with NASA and ESA for later missions. This failure will likely impact those missions, forcing either delays or redesigns.

This mission was always an engineering test mission designed to prove out Astrobotic’s landing design, so experiencing a failure was not a surprise. The problem is that this failure occurred so soon after launch that it prevents the company from testing that landing design, at all.

ULA’s Vulcan rocket successfully places payload in orbit on first launch

1:10 am

Vulcan at liftoff.
Vulcan at liftoff.

After four years of delay, mostly caused by delays at Blue Origin in delivering the two BE-4 engines used in the first stage, ULA’s Vulcan rocket finally completed its first launch early on January 8, 2024, lifting off from Cape Canaveral and successfully placing Astrobotic’s Peregrine lunar lander into orbit.

As of posting the upper stage had just deployed Peregrine, which will leave Earth orbit in about four days using its own engines. The upper stage has one more burn to send it into solar orbit, carrying the ashes of numerous people for the company Celestis.

The 2024 launch race:

3 SpaceX
1 India
1 China
1 ULA

For ULA, this launch is a very big deal. It is the first of two required in order for the Space Force to certify the rocket for future military launches. It also positions the company to begin the many launches that Amazon has awarded it to place into orbit a large percentage of that company’s Kuiper internet satellite constellation, assuming of course Blue Origin can deliver on schedule the many BE-4 engines that ULA will require.

This launch will also likely lead to the sale of ULA. » Read more

NASA: UAE to build airlock module for lunar station plus have astronaut fly there

9:20 am

According to a press release from NASA today, the United Arab Emirates (UAE) will build the airlock module for the Lunar Gateway space station plus have one astronaut fly a mission to the station after it is built.

Under a new implementing arrangement expanding their human spaceflight collaboration with NASA through Gateway, MBRSC will provide Gateway’s Crew and Science Airlock module, as well as a UAE astronaut to fly to the lunar space station on a future Artemis mission.

I strongly suspect that the UAE will mostly pay for this module to be built, hiring outside contractors from either the U.S. or Europe to do the work.

Russia and NASA agree to extend ISS astronaut exchanges on each other’s spacecraft through 2025

Russia and NASA have agreed to extend their barter deal through 2025, whereby each nation sends astronauts to ISS periodically on the other nation’s rockets and capsules.

This is a barter deal, with no exchange of money. The fundamental idea is to make sure astronauts on board ISS understand how the capsules from each nation operate in case of emergency. Russia had initially resisted signing such a deal after SpaceX began providing NASA its Dragon capsules and Falcon 9 rocket to get astronauts to ISS. It said this was because it did not trust SpaceX’s technology, but I suspect Roscosmos was also hoping to squeeze some cash from NASA as it was no longer being paid to fly U.S. astronauts on its Soyuz rocket and capsule. That attempt was futile. For numerous political reasons there was no way NASA was going to pay Russia anything in this barter deal.

Russia then signed on, and will keep extending this agreement until the day ISS is retired, or it finally launches its own station (something that is becoming increasingly unlikely).

Navaho Indians attempt to claim ownership of the Moon, delay Vulcan launch

8:47 am

The president of the Navaho Nation has asked NASA to delay the first launch of ULA’s Vulcan rocket because it carries ashes from a number of people (none who were members of its tribe) that Astrobotic’s Peregrine lander will place on the Moon.

The remains are a payload purchased by the company Celestis, which offers this burial option to anyone who wishes it. On this flight that payload includes a wide range of ashes, including many actors and creators from the original Star Trek series.

Navaho President Buu Nygren claims that the “Moon is sacred to numerous Indigenous cultures and that depositing human remains on it is ‘tantamount to desecration.'”

Nygren highlighted this commitment in his letter, as well as a 2021 memo signed by the Biden administration that pledged to consult the tribe on matters that impact them. “This memorandum reinforced the commitment to Executive Order 13175 of November 6, 2000,” President Nygren wrote. “Additionally, the Memorandum of Understanding Regarding Interagency Coordination and Collaboration for the Protection of Indigenous Sacred Sites, which you and several other members of the Administration signed in November 2021, further underscores the requirement for such consultation.”

In other words, though the Navaho have no plans to ever go there, have done nothing to try to explore it, and have no remains of any tribal members on the flight, he wants to claim the Moon as controlled entirely and forever by the Indian tribes of North America because of a law designed solely to protect specific archeological sites on Earth, where Indian remains are discovered.

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

3:15 pm

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

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

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

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

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

Curiosity takes a close-up of distant cliffs

Close-up of a distant cliff
Click for original image.

Cool image time! The picture to the right, reduced and sharpened to post here, was taken on December 21, 2023 by the chemistry camera (ChemCam) on the rover Curiosity. Originally designed to take close-ups of rocks very nearby the rover, the science team over time discovered that they could also use this camera to get close-ups of very distant objects, providing them another way to study the geology in Gale Crater and on Mount Sharp.

The picture to the right I think shows the horizon area indicated by the arrow on the panorama above, taken the day before. Note the many many layers, a geological feature that Curiosity has discovered is ubiquitous on Mars. Over eons the entire surface of the red planet has been layered repeatedly by cyclical geological events, producing layers within layers within layers. I guarantee that when Curiosity gets closer to this cliff it will see layers inside the smallest layers ChemCam can see now.

The red dotted line on the panorama above indicates the approximate planned route that Curiosity will eventually take, cutting across in front of that mountain and turning south somewhere near but to the west of where the cliff in this picture is located.

Ingenuity’s engineers explain what they have learned flying the helicopter on Mars

9:49 am

Link here. The essay details carefully the problems they have faced, and how they have not only overcome them but used them to refine operations to squeeze far more capabilities out of the helicopter, beyond its initial design.

Saving flight time saves energy, reduces heating, and provides more freedom to use slower speeds to tiptoe around disruptive terrain that might otherwise endanger or significantly degrade the landing accuracy of the helicopter. Higher speeds and higher accelerations reduce the time needed to execute a given flight path. Higher altitudes permit higher speeds, as the wider field of view helps to keep ground features in view of Ingenuity’s navigation camera longer, counteracting the effect of increased speed. Expanding Ingenuity’s flight envelope had the potential to relax flight planning constraints and allow Ingenuity to operate more effectively alongside Perseverance.

As a result, beginning with flight 45 the team has made changes to increase flight speeds and acceleration at every point of every flight, thus allowing the helicopter to fly higher and farther with less strain.

This report however does not provide any information on Ingenuity’s last two flights, especially its 68th, which did not go as planned. The helicopter appears to be in good shape (the team has already planned the 69th flight, which was supposed to happen two days ago), but a more detailed update would be appreciated.

ULA’s Vulcan rocket fully stacked for the first time

9:39 am

Peregrine landing site
The landing site for Astrobotic’s Peregrine lunar lander

In preparation for its targeted January 8, 2024 launch, ULA’s Vulcan rocket has now been fully stacked for first time in its assembly building at Cape Canaveral.

ULA’s new rocket has rolled between its vertical hangar and the launch pad at Cape Canaveral Space Force Station several times for countdown rehearsals and fueling tests. But ULA only needed the Vulcan rocket’s first stage and upper stage to complete those tests. The addition of the payload shroud Wednesday marked the first time ULA has fully stacked a Vulcan rocket, standing some 202 feet (61.6 meters) tall, still surrounded by scaffolding and work platforms inside its assembly building.

It will next be rolled to the launchpad for some final checks prior to launch on January 8, 2023. Unlike most first launches, it carries a real payload, Astrobotic’s Peregrine lunar lander, which hopes to softly place several NASA and commercial payloads near the Gruithuisen Domes in the northwest quadrant of the Moon’s visible hemisphere, as shown on the map above.
