SLS-backer Senator Richard Shelby (R-Alabama) to retire

11:27 am

Senator Richard Shelby (R-Alabama), long time firm supporter of the very expensive and long-delayed Space Launch System (SLS) rocket, has announced that he will not run for office again when his term expires in ’22.

The 86-year-old Shelby was first elected to the Senate in 1986 after eight years in the House. Shelby served in the House, and the first eight years in the Senate, as a Democrat, switching to the Republican party in 1994.

Shelby is best known in the space community for his role shaping NASA programs as a member of the Senate Appropriations Committee. That has included stints as chairman of the commerce, justice and science subcommittee, whose jurisdiction includes NASA, as well as of the full committee. With Democrats in control of the Senate, he is currently the ranking member of the full committee.

“I have worked to enhance Alabama’s role in space exploration and the security of our nation,” Shelby said in the statement announcing his decision not to run for reelection. That’s included support for programs based at the Marshall Space Flight Center in Huntsville, Alabama, such as the Space Launch System. “As chairman of the appropriations committee, I have more than a passing interest in what NASA does. And I have a little parochial interest, too, in what they do in Huntsville, Alabama,” he said at a March 2019 industry event

As the article makes clear, Shelby used his clout unceasingly to keep SLS funded. When NASA simply hinted in 2019 that it might switch to another rocket to launch Orion he made his displeasure known, and NASA immediately backed down.

His resignation now, at the same time that other members of Congress as well as the Biden administration appear to be separating the Artemis lunar program from SLS, is a strong signal that the political winds are blowing badly against SLS. Shelby has probably realized that he no longer has the same support for SLS in the rest of Congress that he once had, and knows there is a good chance it will go away, along with much of the pork he has been funneling to Alabama with it. When that happens, his chances of getting reelected drop precipitously. He probably doesn’t have to inclination to fight what might be a losing battle, especially at the age of 86.

The second static fire test of SLS’s core stage is presently scheduled for the fourth week in February. All had better go well, as time is running out in getting the rocket’s first launch off in ’21. Right now that schedule is very iffy. Further problems will make it impossible.

And any major failures would probably lead to the entire program’s cancellation. It would take years for SLS to recover the loss of the core stage, time the program does not have.

Fiftieth anniversary of Apollo 14 lunar landing

9:22 am

In honor of the fiftieth anniversary today of the landing of Apollo 14 on the Moon, the Lunar Reconnaissance Orbiter (LRO) science team has used images from the spacecraft to map out what the astronauts did on the surface, as shown in the reduced image to the right. The orange and teal lines indicate the routes followed during the two EVAs, with the pink triangles indicating stopping points along the way.

Unlike Apollo 11 and 12, which focused on engineering goals such as landing precisely on the Moon, Apollo 14 focused on addressing science goals. Antares (lunar module) landed in the Fra Mauro highlands, the original destination of the failed Apollo 13 mission, essentially taking on that mission’s objectives. This was the first crewed landing in the lunar highlands and not in the mare.

The Apollo 14 astronauts who landed on the Moon, Alan Shepard (Commander) and Edgar Mitchell (Lunar Module Pilot), completed two extra-vehicular activities (EVAs) while on the surface. They spent a total of 9 hours and 22 minutes setting up equipment, taking photographs, collecting samples, and exploring.

This was the last mission where the astronauts had to walk. The next three Apollo missions brought a rover with them, so that they could drive to their research sites.

NASA awards Firefly lunar contract

9:29 am

Capitalism in space: NASA yesterday announced that it has awarded the new smallsat rocket company Firefly a $93 million contract to build a lunar lander for delivering scientific payloads to the Moon’s surface.

This is the first delivery awarded to Firefly Aerospace, which will provide the lunar delivery service using its Blue Ghost lander, which the company designed and developed at its Cedar Park facility. This facility also will house the integration of NASA and any non-NASA payloads, and also will serve as the company’s mission operations center for the 2023 delivery.

The lander is based on the design of Israel’s Beresheet lunar lander that failed in its landing attempt in 2019. After that failure a group of Israeli engineers from that project formed their own company, and partnered with Firefly to build a new lander, which is now dubbed Blue Ghost.

The NASA contract itself replaces OrbitBeyond, which had won a lunar landing contract initially but had backed out in 2019.

Finally, the timing of this announcement immediately after Firefly had revamped its board of directors to remove its main Ukrainian backer from an obvious management position is most telling. Suggests to me that they did that revamping in direct response to NASA’s concerns, and once done NASA could then move forward with the contract award.

Russia & China negotiating increased cooperation on the Moon

10:21 am

The new colonial movement: According to the state-run Russian news source TASS, Russia and China are in negotiations to increase Russia’s participation in China’s program to establish a manned base on the Moon.

Russia’s state-run space corporation Roscosmos is in talks with its Chinese colleagues to determine scientific tasks for a lunar base and to discuss technical aspects of the project’s implementation, Deputy Director General for International Cooperation at the Russian state space corporation Roscosmos Sergey Savelyev told TASS. “At present, work is under way to determine possible scientific tasks of mutual interest in the Moon research. Besides, possible technical implementation of the project is being analyzed,” he said.

The article is very vague about details. It does signal that Russia is strongly looking for alternatives to working with the U.S. on its Lunar Gateway project. If it teams up with China NASA will likely begin breaking off all cooperation with Russia because of the legal restrictions that prevent it from partnering in any way with China.

This article also illustrates Russia’s declining status as a space power. For years they have depending on the American program at ISS to have a place in space. Now they are looking to China. All in all, it appears they can’t get their own projects going, and need to attach themselves to others to have any part in the exploration of space.

As for China, that country wants to the good public relations that would come from making its space program international in scope. I expect therefore they want Russia to sign on. I also expect that China will dictate terms, as it doesn’t really need Russia in its effort.

NASA delays lunar lander contract award

8:55 am

NASA, now under the control of the Biden administration, has quietly delayed by at least two months the contract award to two companies to build manned lunar landers for its Artemis program.

With short funding from Congress and a new administration focused on more pressing national issues, the move was expected.

Elon Musk’s SpaceX, a team of aerospace giants led by Jeff Bezos’ Blue Origin, and Leidos-owned Dynetics won a combined $967 million in seed funding from NASA last year to develop rivaling concepts for a human lunar landing system. It’s the space agency’s first effort to spend money on astronaut moon landers since the Apollo program in the 1970s.

Last Wednesday, NASA told the three contractors that an extension to their development contracts “will be required,” picking a new award date of April 30th. Under the Trump administration’s timeline, the agency had planned to pick two of the three bidders in late February, giving a stamp of approval for two systems that would inevitably carry humans to the moon.

This delay would likely have occurred under Trump as well, mainly because Congress only appropriated less than a third of the money needed for this Artemis program.

However, under Biden it was guaranteed. A major review is about to happen, designed not to kill Artemis but to slow it down appreciable. Congress likes the pork Artemis produces, but is wholly uninterested in it actually flying any dangerous missions. I suspect Biden will agree. The focus will once again shift back to Gateway, making any lunar landing require it so that it must be built first. Such a shift will guarantee that no American manned missions to the surface of the Moon will occur before ’30, but also allow the spending of gobs of money building a small lunar station that will only be occupied for short periods.

The big loser here, to my mind, is Jeff Bezos. His company, Blue Origin, was building the descent portion of the lunar lander, with all other portions built by his big space partners, Lockheed Martin, Northrop Grumman, and Draper. Not only is most of the other work by these partners more easily shifted to other uses related to Gateway, but those companies already have plenty of government contracts. As far as I can remember, Blue Origin has no other big government deals, with its New Glenn having been rejected by the military, and its lunar descent technology unneeded until there is a lunar landing, and I expect that to be significantly delayed.

For the past four years Bezos has clearly wanted to make Blue Origin a new big space contractor. Right now it appears that effort has failed wholly.

Dynetics will also lose out big, as they are a new company and can ill afford losing a contract here.

SpaceX will likely be hurt the least. Not getting any money for designing Starship to land on the Moon will do little to slow its development. Starship is almost completely privately funded, and does not need NASA money to get built.

New Democrat head of House subcommittee covering NASA says he supports Artemis

9:32 am

The new Democrat head of the House appropriations subcommittee that covers NASA funding, Matt Cartwright (D-Pennsylvania), appears to support the Artemis program established during the Trump administration, though he has also indicated that he does not favor the timeline imposed by Trump to land a manned mission on the Moon by ’24.

Cartwright’s embrace of Artemis during [a] July 2020 webinar was a change from 2019 when he was one of several members reacting skeptically to a supplemental budget request from the Trump Administration after it unexpectedly accelerated the timeline for putting people back on the Moon from 2028 to 2024. He complained NASA did not even have a cost estimate for the entire effort, yet expected Congress to embrace it.

In 2018, he expressed concern about proposed cuts by the Trump Administration to NASA’s earth and space science activities especially climate programs and WFIRST (now the Roman Space Telescope). He urged NASA to follow the Decadal Surveys produced by the National Academies of Sciences, Engineering, and Medicine.

What his prior views presage now that he chairs the subcommittee remains to be seen. It is widely expected the 2024 deadline will be pushed back, perhaps to the 2028 date NASA originally planned, but Cartwright appears favorably disposed towards the agency overall.

Delaying the Moon landing by SLS forever is the real goal, so the jobs program can be extended without any risks. To actually fly might result in a failure, something that no politician wants.

In the end it will not be SLS anyway that gets Americans back to the Moon. It costs too much and is badly designed. It might fly once or twice, but after that Congress will drop it while keeping Artemis, albeit in a very different form. Instead of having NASA design and build things, the new Artemis will be built by the many companies who were awarded fixed priced contracts during the Trump administration to develop their own hardware as fast as possible and as inexpensively as possible.

The distinction is important, because the latter is more likely to succeed in a reasonable amount of time.

At the same time, with Congress on board and a Democrat in the White House, it is not surprising that the policy is immediately shifting to a slower timeline. Can’t get this done too fast! I must also add that 2028 was not NASA’s original date for its return to the Moon. Before the Trump administration took control of Artemis, NASA had wanted to complete Gateway first, which based on all of NASA’s previous schedules would have pushed a lunar landing into the 2030s. Do not be surprised if this sluggish schedule is reinstated.

In fact, with the present incompetents in charge in Washington, I fully expect China to own the Moon, while U.S. politicians brainlessly dither on how to spend pork.

Chang’e-5’s lunar samples less dense than expected

8:59 am

Because the lunar samples retrieved by China’s Chang’e-5 probe were less dense than expected, it ended up recovering only 3.8 pounds of material rather than the targeted 4.4 pounds.

The probe had estimated the lunar rocks to have a density of 1.6 grams per cubic millimetre, based on data from past missions by other countries, said Pei Zhaoyu, the mission spokesman. Going by that figure, the probe stopped taking samples after just 12 hours, apparently assessing that the target had been reached. “However, from tests, the actual density might not be that high,” Pei told reporters.

This is not a failure, but a discovery. In order to make sure the lander did not recover too much material, weighing too much, they needed to set limits based on the expected weight of the material recovered. That these samples taken from the Mons Rümker volcano complex are lighter than expected reveals something about them. It suggests the lava here was different than lava samples taken elsewhere.

The conjunction of Jupiter and Saturn, as seen from the Moon

9:21 am

Jupiter and Saturn as seen by LRO
Click for full image.

With Jupiter and Saturn closer to each other in the sky than they have been in about 800 years, the science team for Lunar Reconnaissance Orbiter (LRO) decided to aim that lunar orbiter at the two gas giants to get a picture.

The photo to the right, cropped and expanded to post here, was also enhanced by the science team to brighten Saturn so that it would match Jupiter. As they note at the link,

[LRO] captured this view just a few hours after the point of closest separation (0.1°) between the two giant planets. With the sharp focus of the NAC [camera], you can see that the two planets are actually separated by about 10 Jupiter diameters

Both planets however look fuzzy in the image, probably because the camera was not designed to obtain sharp images from this distance. Nonetheless, this is a very cool photo.

Chang’e-5 lunar orbiter heading to Sun-Earth Lagrange point

8:56 am

The new colonial movement: Chinese engineers have decided to extend the mission of the Chang’e-5 lunar orbiter by shifting its orbit so that it is transferred to one of the five Sun-Earth Lagrange points.

Amateur radio operators first confirmed the Chang’e-5 orbiter was still in space and heading towards the moon. Official confirmation has now been provided as to the spacecraft’s status.

Hu Hao, a chief designer of the third (sample return) phase of the Chinese lunar exploration program, told China Central Television (Chinese) Dec. 20 that the orbiter is now on an extended mission to a Sun-Earth Lagrange point. Hu said the extended mission was made possible by the accurate orbital injection by the Long March 5 launch vehicle, the same rocket which failed in July 2017 and delayed Chang’e-5 by three years. The Chang’e-5 orbiter has more than 200 kilograms of propellant remaining for further maneuvers.

While unspecified, it is believed that the Chang’e-5 orbiter will enter orbit around L1, based on the reference to planned solar observations. The orbiter is equipped with optical imagers. The team will decide on a further destination after tests and observations have been conducted, Hu said.

It makes great sense to keep the orbiter operating, and since lunar orbits tend to be unstable, going to a Lagrange point makes even more sense.

However, this decision raises an interesting point for the future. There are only five Lagrange points in the Earth-Sun system. All have great value. All also can likely sustain a limited number of satellites and spacecraft. Who coordinates their operations? What happens if China fills each with its spacecraft? For example, the James Webb Space Telescope is aiming for Lagrange point #2, a million miles from Earth in the Earth’s shadow. While Chang’e-5 is presently heading to a different point, what happens if China changes its mind and puts Chang’e-5 in Webb’s way?

As far as I know, there has been no discussion of this issue in international circles.

Samples from space!

9:16 am

Scientists from both the Japanese Hayabusa-2 mission to the asteroid Ryugu and the Chinese Chang’e-5 mission to the Moon announced yesterday the total amount of material they successfully recovered.

The numbers appear to diminish the Japanese success, but that is a mistake. Getting anything back from a rubble-pile asteroid that had never been touched before and is much farther away from Earth than the Moon was a very great achievement. The 5.4 grams is also more than fifty times the minimum amount they had hoped for.

This is also not to diminish the Chinese achievement, They not only returned almost four pounds, some of that material also came from a core sample. They thus got material both from the surface and the interior of the Moon, no small feat from an unmanned robot craft.

Scientists from both nations will now begin studying their samples. Both have said that some samples will be made available to scientists from other countries, though in the case of China it will be tricky for any American scientist to partner with China in this research, since it is by federal law illegal for them to do so.

Chang’e-5 sample return capsule successfully recovered in China

6:18 pm

The new colonial movement: The sample return capsule for China’s Chang’e-5 mission, the first to bring lunar samples back to Earth since 1976, has been successfully recovered in the inner Mongolia region of China today.

Chinese officials confirmed the roughly 660-pound (300-kilogram) capsule landed at 12:59 p.m. EST (1759 GMT) Wednesday, or 1:59 a.m. Thursday in Beijing.

Recovery crews dispatched to the remote landing zone converged on the capsule in helicopters and off-road vehicles, traveling across the snow-covered plains of Inner Mongolia in the middle of the night. Ground teams reached the Chang’e 5 return module within minutes to begin operations to secure the capsule, and planted a Chinese flag in the frozen soil next the spacecraft.

Crews plan to transport the module to Beijing, where scientists will open the sample carrier and begin analyzing the moon rocks.

For China this success is a major milestone for its government-run space program. They have demonstrated superb technical capabilities that will serve them on many more future missions. They have also signaled to the world and the U.S. that they mean business in space, and that their published plans to build colonies on the Moon are serious. They have also made it clear that they will enforce control over any territory they occupy, notwithstanding the rules of the Outer Space Treaty. Any American government that makes light of these facts and refuses to aggressively compete with China is going to quickly discover it shut out of the most valuable locations on the Moon.

Chang’e-5 on its way back to Earth

3:04 pm

The new colonial movement: Chang’e-5 today successfully fired four engines for 22 minutes to leave lunar orbit and begin its journey back to Earth, with a planned arrival date in China for its sample return capsule around December 15/16th.

The return capsule is expected to land in northern China in the Inner Mongolia region after separating from the rest of the spacecraft and floating down on parachutes. The material would be the first brought back since the Soviet Union’s Luna 24 probe in 1976.

The rocks and other debris were obtained both by drilling into the moon’s crust and scooping directly off the surface. They may be billions of years younger than those brought back by earlier U.S. and Soviet missions, possibly offering insights into the moon’s history and that of other bodies in the solar system.

The landing sequence is the last major engineering challenge, though hardly as challenging as the autonomous rendezvous and docking in lunar orbit.
