China launches two GPS-type satellites

China today successfully placed two more of its BeiDou GPS-type satellites into orbit, its Long March 3B rocket lifting off from its Xichang spaceport in the southwest of China.

This footage shows that the rocket’s core stage crashed near homes in China. No word on where the four strap-on boosters and second stage crashed. All use very toxic hypergolic fuels.

This launch continues China’s annual rush of launches at the end of the year. Since everything is owned and run by the Chinese government, one wonders if this pattern is because of the typical government mentality that requires agencies to rush to spend a lot at the end of each year so as to make sure their budgets are not cut.

The leaders in the 2023 launch race:

94 SpaceX
64 China
18 Russia
8 Rocket Lab
7 India

American private enterprise still leads China in successful launches 108 to 64, and the entire world combined 108 to 100. SpaceX in turn trails the rest of the world (excluding other American companies) 94 to 100.

Core stage of China’s Long March 5 launched on December 15th about to hit the Earth

According to the Chinese government, the core stage of Long March 5 that China launched on December 15th will hit the Earth tomorrow, somewhere in the South China Sea.

China warned that remnants of a rocket would hit an area in the South China Sea on Tuesday, following the sixth deployment of its most powerful launch vehicle eleven days ago.

Rocket debris, which generally burns up in the atmosphere on re-entry, is expected to fall off the coast of China’s island province of Hainan between 11:00 a.m. (0300 GMT) and noon (0400 GMT), said the China Maritime Safety Administration.

I have not been able to find out any further information about this rocket body from sources like the Aerospace Corporation that normally track such things. However, that China is predicting a landing spot suggests they have upgraded the engines on the Long March 5’s core stage so that they can be restarted and used to control the stage’s descent over the ocean. If so, this is excellent news, as China has stated that it intends to ramp up launches of this rocket as well as its Long March 5B variation. Prevous launches produced the threat of impacts anywhere on Earth, with one launch in 2020 missing the New York metropolitan area by only a few minutes.

That China wants to bring this down so close to China suggests it also wants to salvage the material.

December 19, 2023 Zimmerman/Space Show podcast

Last week, on December 19, 2023, I appeared on the Space Show with David Livingston. You can listen or download it here. I am posting the link to the podcast now, almost a week later, because both of us forgot to do so, David to send me the link and I to ask him for it.

Twas a good show. For me the highlight was the conversation with Charles Lurio of the Lurio Report, who admitted he had finally come around to my way of thinking in connection with delays to SpaceX caused by the abuse of power by the FAA, Fish & Wildlife, and likely the White House. He like too many journalists covering the space industry had thought I was being paranoid. Charles however kept an open mind. He watched what was happening rather than look the other way, and now recognizes that politics and mindless bureaucracy is certainly playing a part in these delays. It must not be ignored.

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

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.

Japan’s SLIM lunar lander enters orbit around Moon

SLIM's landing zone
Map showing SLIM landing zone on the Moon.
Click for interactive map.

After almost four months of orbital maneuvers since its launch on September 7, 2023, Japan’s SLIM lunar lander entered lunar orbit today, with a targeted landing date of January 20, 2024.

The landing site is indicated by the map to the right near Shioli Crater. SLIM is mostly an engineering test mission, with its primary goal to test an autonomous unmanned landing system capable of putting a lander down within a small target zone of less than 300 feet across. It has some science instruments on board, but any data obtained from them will be an added bonus, since the lander is only designed to operate for about two weeks, during the first lunar day. It is not expected to survive the two-week long lunar night to follow.

Because of launch delays for both of the American landers, Intuitive Machine’s Nova-C and Astrobotic’s Peregrine, SLIM will make its attempt first.

China launches four weather satellites

China late today used its Kuaizhou-1A solid-fueled rocket to place four weather satellites into orbit, lifting off from its Jiuquan spaceport in the northwest of China.

No word on where the rocket’s lower stages crashed within China. This launch is the first of four Chinese launches known to be scheduled in the next few days, part of China’s typical rush of launches that seems to happen at the end of every year.

The leaders in the 2023 launch race:

94 SpaceX
62 China
18 Russia
8 Rocket Lab
7 India

American private enterprise still leads China in successful launches 108 to 62, and the entire world combined 108 to 98. SpaceX in turn trails the rest of the world (excluding other American companies) 94 to 98.

SpaceX launches two German military radar satellites

SpaceX today successfully launched two German military radar surveillance satellites, completing a planned three-satellite constellation, with its Falcon 9 rocket lifting off from Vandenberg Space Force Base in California.

The first stage completed its eighth flight, landing back at Vandenberg.

This launch almost certainly in the past would have launched on a Arianespace rocket, but Arianespace presently has no operational rocket, its Ariane-5 rocket retired and its Ariane-6 rocket not yet operational. Furthermore, its Vega and Vega-C rockets are grounded due to launch failures, and its partnership with Russia ended with Russia’s invasion of the Ukraine. Thus, SpaceX gets the business, being less expensive than ULA (which also has no rockets available right now to handle this launch) and there being no other company capable of launching such a payload.

The leaders in the 2023 launch race:

94 SpaceX
61 China
18 Russia
8 Rocket Lab
7 India

American private enterprise now leads China in successful launches 108 to 61, and the entire world combined 108 to 97. SpaceX now trails the rest of the world (excluding other American companies) 94 to 97.

SpaceX launches 23 Starlink satellites

Early on December 23, 2023 SpaceX successfully launched another 23 Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral.

The first stage successfully completed its 19th flight, landing on a drone ship in the Atlantic. This reuse was new record. In fact, the reuse numbers of SpaceX’s fleet Falcon 9 first stages are beginning to resemble the reuse numbers of NASA’s shuttle fleet, and are doing so in a significantly shorter period of time and for a lot less money.

The leaders in the 2023 launch race remain the same:

93 SpaceX
61 China
18 Russia
8 Rocket Lab
7 India

American private enterprise now leads China in successful launches 107 to 61, and the entire world combined 107 to 97. SpaceX now trails the rest of the world (excluding other American companies) 93 to 97.

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.
