Chang’e-4 and Yutu-2 reactivated for 29th lunar day

8:28 am

Chinese engineers have reactivated their Chang’e-4 lander and Yutu-2 rover, beginning their 29th lunar day on the far side of the Moon.

As is usual from the state-run Chinese press, the article provides little other detail, other than stating that Yutu-2 ” will continue to move northwest toward the basalt distribution area located about 1.2 km away from the rover.” That’s about 3,900 feet. Based on Yutu-2 pace of moving about 100 feet per lunar day, it will be more than three years before it reaches that goal.

South Korea’s leader announces his nation’s goals in space

2:53 pm

The new colonial movement: Moon Jae-in, South Korea’s president since 2017, on March 25th gave his first speech focused on his nation’s goals in space, outlining plans to encourage private enterprise as well as achieving an unmanned mission to the Moon by 2030.

His speech listed three main programs. First, they are developing their own home-built rocket, dubbed the KSLV-2, which they hope to launch on its first orbital test flight by October of this year.

Second, he touted a project to send a probe to the asteroid Apophis in 2029. I described this probe in my November 2020 report on a science conference focused entirely on Apophis. If all goes well, they hope to have the probe fly in formation with the asteroid as it makes its close approach that year.

Third, he committed his nation to landing an unmanned lander on the Moon by the end of this decade. (Sound familiar?)

While much of this was the typical photo-op stuff that politicians love, designed mostly to enhance their public image, Moon did make it clear their goals are also to foster a new private aerospace industry that would compete in the emerging new space market.

Moon underscored the role of the private sector in enhancing Korea’s space development capabilities. To that end, he said, the government will step up efforts to build an “innovative industrial ecosystem that nurtures global space companies such as SpaceX.”

Another issue he put forth was strengthening international competitiveness of made-in-Korea satellite systems, in the lead-up to the introduction of 6G wireless networks, self-driving vehicles, and other products and services enabled or enhanced by satellites.

All-in-all, it is actually surprising that up to now South Korea has not made its presence felt in space. This announcement suggests they now intend to change that.

Yutu-2 & Chang’e-4 complete 28th lunar day on Moon

8:42 am

The new colonial movement: China’s lunar rover Yutu-2 and its lander Chang’e-4 have successfully completed their 28th lunar day on the far side of the Moon, and have been placed in hibernation for the long lunar night.

According to this article from China’s state-run press, Yutu-2 has now traveled 683 meters (2,241 feet) since its landing. In the past two lunar days the rover has traveled about 180 feet, continuing its journey to the northwest away from Chang’e-5. Their pace continues to be about 80 to 100 feet per lunar day.

Glynn Lunney, R.I.P

10:18 am

NASA flight director Glynn Lunney has passed away at the age of 84.

He not only was one of the flight directors in Houston that helped get astronauts to the Moon in 1969, he was also instrumental in getting the crew of Apollo 13 back home when their service module failed in 1970.

Lunney and his team were just about to come on console for the evening shift on April 13, 1970, when the Apollo 13 crew radioed, “Houston, we’ve had a problem.”

“For me, I felt that the Black Team shift immediately after the explosion and for the next 14 hours was the best piece of operations work I ever did or could hope to do,” Lunney said in his oral history. “It posed a continuous demand for the best decisions often without hard data and mostly on the basis of judgment, in the face of the most severe in-flight emergency faced thus far in manned spaceflight.”

“We built a quarter-million mile space highway, paved by one decision, one choice, and one innovation at a time — repeated constantly over almost four days to bring the crew safely home. This space highway guided the crippled ship back to planet Earth, where people from all continents were bonded in support of these three explorers-in-peril,” he said. “It was an inspiring and emotional feeling, reminding us once again of our common humanity. I have always been so very proud to have been part of this Apollo 13 team, delivering our best when it was really needed.”

He had been part of NASA when it was young (as he was) and honest and dedicated to accomplishing its goals fast and efficiently and — most significantly — with courage. May he rest in peace.

China and Russia sign partnership agreement for lunar exploration

2:11 pm

The new colonial movement: China and Russia today signed an agreement outlining a partnership to jointly build a base and orbiting station on and around the Moon.

The International Lunar Research Station (ILRS) is described as a comprehensive scientific experiment base built on the lunar surface or on the lunar orbit that can carry out multi-disciplinary and multi-objective scientific research activities including exploration and utilization, lunar-based observation, basic scientific experiment and technical verification, and long-term autonomous operation. Statements from Roscosmos and CNSA underline that the project will be “open to all interested countries and international partners.”

Though not explicitly stated it is understood that the ILRS would be constructed at the lunar south pole.

Russia is slowly breaking off its partnership with the U.S. because the U.S. is insisting it sign the Artemis Accords, which require all signatories to honor property rights in space. Neither Russian nor China wish to do that, instead reserving those rights wholly to their own governments, their citizens be damned.

Thus, we have a deal for Russia and China to work together. China actually doesn’t need Russia, as it has clearly shown in the past five years that its space capabilities are quite sufficient and well funded. Russia however needs China, as its capabilities have been declining in recent years due to corruption within its aerospace industry as well as a shortage of funds caused by a poor economy and the drop in oil prices.

Working together however could help speed what they achieve while simultaneously fueling the growing international competition in space. In the end this will benefit everyone, as more will get done faster.

How we shall settle the disagreement over property rights and government power in space is a entirely different question, one that I address at great length in my next soon-to-be published book, entitled Conscious Choice: The origins of slavery in America and why it matters today and into the future. Stay tuned!

Yutu-2 and Chang’e-4 reactivated for 28th lunar day on Moon

9:01 am

The new colonial movement: Engineers have reactivated both Yutu-2 and Chang’e-4 to begin their 28th lunar day on the far side of the Moon.

The article, from China’s state-run press, provides only one real tidbit of information, that Yutu-2 has now traveled 429 meters (1,378 feet) from the landing site. They still have about a mile to go to reach their next big geological target, which should take years at the pace the rover is setting.

Both spacecraft though have been unmitigated successes. Their nominal mission had been to survive three lunar day-night cycles, about 90 Earth days. They have survived 28, or more than two years since landing in January 2019.

This success suggests that China’s Mars rover has a good chance of doing as well. Its planned mission length is also 90 days, similar to the Spirit and Opportunity rovers, both of which lasted many years.

NASA lunar rover experiences big budget overruns

9:48 am

NASA revealed yesterday that the budget for VIPER, a new NASA-built lunar rover, has increased from $250 million to $433.5 million.

The cost of the mission has gone up significantly. At the time NASA announced VIPER in October 2019, it projected a cost of about $250 million. As part of the confirmation review, known as Key Decision Point C, NASA set a formal cost commitment for the mission. NASA spokesperson Alison Hawkes said March 3 that the new lifecycle cost for the mission is $433.5 million.

NASA didn’t disclose the reason for the cost increase, but NASA officials said in June 2020 that they were postponing VIPER’s launch by about a year to late 2023 to change the rover’s design so it can meet the goal of operating for 100 days on the lunar surface. At the time, the agency declined to comment on VIPER’s cost.

This is very typical of modern NASA. Even though its planetary program produces some spectacular spacecraft and results, that program — like all NASA-built programs — rarely does so for the budget promised. For the planetary program, however, the overage for VIPER is startlingly high, especially in so short a time.

Be prepared for more delays and overages for this project, since that is usually what happens for NASA projects that experience such large budget increases.

Maezawa looking for volunteers for his Starship flight around Moon

10:32 am

Capitalism in space:
Yusaku Maezawa, the Japanese billionaire who has purchased a flight on SpaceX’s Starship to fly around the Moon, is now looking for volunteers to join him.

The Japanese entrepreneur said applicants would need to fulfill just two criteria: being ready to “push the envelope” creatively, and being willing to help other crew members do the same. In all, he said around 10 to 12 people will be on board the spaceship, which is expected to loop around the moon before returning to Earth.

The application timeline for spots on the trip calls for would-be space travellers to pre-register by 14 March, with initial screening carried out by 21 March. No deadlines are given for the next stages – an “assignment” and an online interview – but final interviews and medical checkups are currently scheduled for late May 2021, according to Maezawa’s website.

Both he and SpaceX are still aiming for a 2023 flight, though that date is likely optimistic.

To apply, go here.

Apollo 16 Lunar Rover “Grand Prix”

6:01 pm

An evening pause: This seems especially appropriate with the arrival of another rover on Mars last week.

On their first day of three on the lunar surface, John Young and Charles Duke deployed their rover and took it for a test drive before heading out to nearby Plum Crater for two hours of sample gathering and exploration.

This footage shows Young driving with Duke filming and reporting what he sees. The goal was to gather engineering data on how the rover’s wheels functioned in the very dusty lunar soil.

This short clip nicely illustrates the ambitious achievement of the American Apollo missions that should give pause to any arrogant modern young engineer. This was before home computers and CAD-CAM. It was designed by hand and slide-rule, using inches, pounds, and feet. And it worked, and worked magnificently. Oh if we today could only do as well.

India officially delays both its manned mission and next lunar lander

9:47 am

The new colonial movement: India has now officially delayed the launch of both its manned mission Gaganyaan as well as its next lunar lander/rover Chandrayaan-3.

They hope to launch an unmanned test Gaganyaan mission before the end of this year, but the manned mission will not occur until after a second unmanned mission scheduled very tentatively in the 2022-2023 time frame.

As for Chandrayaan-3, they had initially hoped to launch it last fall, but they panic over the coronavirus that shut down their entire space industry for a years has now apparently pushed that launch back ’22, a delay of more than a year.

Hungarian company awarded NASA contract to develop Moon mini-rover

4:49 pm

A Hungarian company has won a NASA contract worth $225K to develop what the company calls its Puli Moon mini-rover.

Named after a Hungarian breed of dog, the Puli rover is a low-cost platform designed to carry different payloads, including the ice water snooper, which won the 2020 “Honey, I Shrunk the NASA Payload” challenge, a competition organised by the U.S. space agency. Weighing less than 400 grammes (14 oz), its purpose is to probe for water ice by identifying and mapping the subsurface hydrogen content of the lunar soil.

The “news article” at the link appears to be a poorly researched article distributed by Reuters that has now been reprinted without changes by such stalwart American mainstream news outlets like the New York Post and MSN.com, to name two. Neither bothered to do any further research.

The article falsely claims that the airplane-based SOFIA telescope recently confirmed there is water on the Moon. It also claims that this rover will be on a lunar mission next year, something that does not seem likely at all.

A look at the company’s website clarifies things. The company competed in a NASA contest offering its design of a very tiny lightweight rover, won, and was then awarded a larger development contract of $225K. No launch is presently set, though if the company is successful in building it for this cost, they will likely get a berth on a later unmanned mission.

Momentus signs deal to deliver two private cubesats to lunar orbit

11:55 am

Capitalism in space: Momentus has signed a deal with a Singapore startup to provide the transportation to lunar orbit of two cubesats using its next generation space tug.

Momentus Inc. (“Momentus” or the “Company”), a commercial space company offering in-space infrastructure services, and Qosmosys, a new space venture founded in Singapore last year, announced today a service agreement to deliver two cubesats to low lunar orbit as early as 2024 via Momentus’ inaugural lunar mission.

The new contract builds and expands on the agreement announced in January 2021 for delivery of up to four cubesats in low Earth orbit by Momentus’ Vigoride service vehicle, starting in 2022. Qosmosys will expand its novel business ideas to the Moon using a specific bus named Zeus-MS, a version of its Zeus platform it has been developing in cooperation with NuSpace from Singapore, and made specific for lunar missions. Zeus-MS is the precursor to a series of multi-mission platforms that will allow organizations and businesses to host their payloads, and will offer individuals a bespoke, unprecedented line of services to the Moon on regularly scheduled flights.

“We are excited to partner with Momentus again, now onboard Ardoride’s inaugural lunar mission in 2024,” said Francois Dubrulle, CEO of Qosmosys. “Our vision is to make space accessible to all, and Momentus will help us achieve this goal through their efficient orbital services.”

Ardoride, the next generation service vehicle after Vigoride, will extend the range and capabilities of Momentus’s services beginning in 2023.

It is unclear who Qosmosys’ customers are for their lunar Zeus-MS cubesat platform, but I have no doubt they have plenty, many from the university community. For example, universities fund student-built cubesats for educational purposes. Why not make this a project to the Moon, rather than just in Earth orbti? The cost difference would not be much using these new private companies.

Rover update: The rovers are coming! The rovers are coming!

12:52 pm

With the imminent landing on Mars of both the American rover Perseverance only days away on February 18th followed by China’s rover in April, I think it time for a new rover update, not only providing my readers a review of the new landing sites but a look at the most recent travels of Curiosity on Mars and Yutu-2 on the Moon.

Curiosity

Overview map of Curiosity's most recent and future travels

The panorama above, made from four images taken by Curiosity’s right navigation camera on February 12, 2021 (found here, here, here, and here), looks south to the base of Mount Sharp, now only a short distance away. The yellow lines on the overview map to the right show the area this panorama covers. The white line indicates Curiosity’s previous travels. The dotted red line in both images shows Curiosity’s planned route.

The two white dots on the overview map are the locations of the two recurring slope lineae along Curiosity’s route, with the plan to get reasonable close to the first and spend some time there studying it. These lineae are one of Mars’ most intriguing phenomenon, seasonal dark streaks that appear on slopes in the spring and fade by the fall. There are several theories attempting to explain their formation, most proposing the seepage of a brine from below ground, but none has been accepted yet with any enthusiasm.

Turkey to do lunar mission, send astronaut into space

8:59 am

The new colonial movement: Turkey’s leader, Tayyip Erdogan, announced yesterday a new space exploration initiative that will include sending an unmanned probe to the Moon as well as flying an astronaut into space.

“The first rough landing will be made on the moon with our national and authentic hybrid rocket that shall be launched into orbit in the end of 2023 through international cooperation,” Erdogan said, detailing a two-phase mission. Erdogan did not elaborate further on the cooperation. Last month, Erdogan spoke to Tesla and SpaceX boss Elon Musk on possible cooperation in space technologies with Turkish companies.

Speaking in an event in Ankara, Erdogan announced a programme with 10 strategic goals including sending a Turkish citizen to a scientific mission in space.

The manned mission will not be flown by Turkey, but will be purchased from someone else, either Russia or SpaceX or Boeing maybe even China.

The timing of this announcement, the same day the UAE’s Al-Amal probe entered Mars’ orbit, suggests it was prompted by that success, and is an example of keeping up with the Joneses. Whether there is any reality to these proposals however remains to be seen.

ESA contracts Airbus to build three more Orion service modules

11:38 am

The European Space Agency (ESA) late last week announced that it has awarded Airbus a contract to build three more service modules for NASA’s Orion capsule.

This new contract supplements the existing contract that already has Airbus building three service modules. With six service modules in the pipeline, the ESA is signaling that it is very confident the Artemis program will continue.

The key question remains: Will it continue with SLS as the rocket of choice? Right now there simply aren’t the funds to build six SLS rockets. Congress has only funded two. Moreover, the pace of construction for SLS means that, if funded, it will likely take a decade at least for it to launch these six capsule/service modules. Since SpaceX’s Starship/Super Heavy will likely be operational in about half that time, and will also be capable of much more for far less, I suspect that if these additional Orion capsules get launched, they will do so on something other than SLS.

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

Apollo 14 as seen by LRO
Click for full image.

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.

New data confirms and localizes uplifted lunar dust as seen by Apollo astronauts

1:11 pm

The uncertainty of science: In a paper released today, scientists reveal the detection of electrostatic dust events on the Moon similar to those observed by Apollo astronauts, and find that these events might not be global but instead confined to craters during twilight. From the abstract:

Lunar horizon glows observed by the Apollo missions suggested a dense dust exosphere near the lunar terminator. But later missions failed to see such a high‐density dust exosphere. Why the Apollo missions could observe so large number of dust grains remains a mystery. For the first time, we report five dust enhancement events observed by the Lunar Dust Experiment on board Lunar Atmosphere and Dust Environment Explorer [LADEE] mission, which happen near a twilight crater with dust densities comparable to the Apollo measurements. Moreover, the dust densities are larger on the downstream side of the crater and favor a higher solar wind temperature, consistent with an electrostatic dust lofting from the negatively charged crater floor. We also check the Apollo observations and find similar twilight craters, suggesting that the so‐called dust exosphere is not a global phenomenon but just a local electrified dust fountain near twilight craters.

The dust clouds the astronauts thought they saw near the horizon have been theorized to be dust uplifted by static electricity. However, all later missions had so far failed to detect this phenomenon, until now. That the result also pinpoints the location and ties it to twilight is important for future missions to the Moon. Astronauts can thus minimize any damage by this dust by shutting down operations during lunar twilight periods.

Beresheet-2 will have two landers instead of one

8:42 am

The new colonial movement: SpaceIL, the Israeli non-profit company that built the failed Beresheet-1 lunar lander, yesterday announced its plans to build Beresheet-2, this time with an orbiter and two lunar landers, and launch it by ’24.

The two landers would be much smaller than the first spacecraft — about 260 pounds each, fully fueled, compared with a bit less than 1,300 pounds for Beresheet — and they would land on different parts of the moon. The orbiter would circle the moon for at least a couple of years. The three spacecraft of Beresheet 2 would together weigh about 1,400 pounds.

Even though the designs would be new, they would reuse many aspects of Beresheet, and the founders said they had learned lessons that would increase the chances of success for the second attempt. SpaceIL will again collaborate with Israel Aerospace Industries, a large satellite manufacturer.

SpaceIL is looking for funding from both private and Israeli government sources. It is also looking for funds from other nations, a decision which revealed the most intriguing part of this announcement:

SpaceIL hopes that international partnerships will pay for half of the cost of Beresheet 2. Mr. Damari said the United Arab Emirates, a small but wealthy country in the Persian Gulf that has set up an ambitious space program in recent years, was one of seven nations interested in taking part. He declined to name the other six.

If this flight ends up to be a partnership between Israel and the United Arab Emirates it will send shockwaves through the Arab world, most especially among the supporters of the terrorist leaders ruling the Palestinian territories.

Mysterious object in solar orbit identified as upper stage for Surveyor 2

9:14 am

Since August astronomers have been trying to figure out the nature of a mysterious object in solar orbit that did not match their expectations for either a comet or an asteroid. Dubbed 2020 SO, astronomers have now identified it as the upper stage booster used to send the unmanned lunar lander Surveyor 2 towards the Moon in 1966.

Surveyor 2 was a failure when it began tumbling and crashed into the Moon instead of doing a soft landing. Its upper stage meanwhile was sent on a path that would have it miss the Moon and go into orbit around the Sun. That orbit finally brought it back to Earth this year.

2020 SO was captured by Earth’s gravity in November and came within 27,400 miles from Earth on December 1. That’s when Reddy and his colleagues at the IRTF were able to capture the infrared spectrum of another Centaur D rocket booster—this time from a 1971 launch of a communication satellite. When they compared that spectrum to the data gathered about 2020 SO, the spectra matched. 2020 SO is also a Centaur rocket booster, most likely the one used for the Surveyor 2 mission.

2020 SO is now moving away from the Earth and should escape Earth’s gravity within a few months, at which point it will follow a new solar orbit. But astronomers expect it to return to Earth in 2036, and they will be ready to learn even more when it does.

This booster is essentially an early example of space archeology. Someday colonists in space will go and catch it to bring it back to one of their museums on the Moon or Mars, to be studied and admired as a major marker of their own past history.
