The China National Space Administration (CNSA) Watcher site posted the above before and after selfies taken by the Zhurong Mars Rover. The top shot was taken on May 19, 2021 and the bottom shot on January 22, 2022. You can see the dust that has accumulated in less than a year on the rover’s panels. The site notes that the rover has the ability to vibrate and loosen the accumulated dust.
China launched Tianwen-1, which carried the rover, on July 23, 2020. It went into orbit around Mars in February 2021, with the Zhurong Rover landing on the Martian surface on May 14, 2021. China sent the rover to the Red Planet to find evidence of water. If all goes well, China hopes to bring a Martian samples back to Earth in a subsequent mission. The Planetary Society has some helpful information here on the Chinese mission.

Over the weekend, the Washington Post published an editorial by Homer Hickam, former NASA engineer and advisor to the National Space Council, titled, “Our space partnership with Russia can’t go on.” In the piece, Mr. Hickam argues that the International Space Station (ISS) has accomplished its goals and the US can now move onto other projects without the Russians:
With our flourishing commercial space companies, who are already cutting metal on their own future space stations, plus our federal government’s Artemis moon program, the United States is entering a new golden age of space exploration. The Russians, meanwhile, are stuck in the past with antiquated spacecraft and nowhere to go except the ISS.
Mr. Hickam appears to believe pushing out the Russians may mean the end of the ISS. Of course, this is just one man’s view, and whatever we do we need to do it in conjunction with our other ISS partners.
We could continue to maintain the ISS through 2030, as planned, and schedule more useful science even without the Russians as partners. This may make sense until we have another viable station that we can use, such as NASA’s planned lunar Gateway. Russia will not be part of the Gateway given that it is working with China on other lunar plans, so we do not need to worry about another breakup.
It would be better if Russia had focused on its space accomplishments rather than territorial ambitions as it prepares for the future. Joint space programs are a great way to use rockets for peaceful missions. I am not against a space race that pushes us even farther into space, yet I would prefer it be fueled by scientific achievement rather than nationalist angst.

As much as we talk about cooperation in space, it is always nice to be the first nation to pass a milestone, be it the first man on the Moon or the first probe of Pluto. The U.S. has plenty of great stories about space travel, as do the Russians, and now the Chinese are creating their own stories. For instance, China’s Yutu 2 rover was the first rover to explore the dark side of the Moon.
A linchpin of the NASA moon effort is the Space Launch System, the Boeing-built mega-rocket that has been beset by years of delay and cost overruns that is finally set to make its maiden test flight in 2022.
The U.S., Russia, and China all have designs on the moon:
The U.S. moon program has been enlisting international partners in the form of the Artemis Accords, which now includes more than a dozen countries. But Russia and China, which are pursuing a lunar research station, are also seeking partners.
We already know that the U.S. hopes to have astronauts on the Moon in 2024, so what are the Russian and Chinese schedules for their projects? It appears the two nations are working on a joint lunar research base scheduled for the 2030s. However, not everyone is convinced this will happen. A Foreign Policy article, “A Chinese-Russian Moon Base? Not So Fast,”voiced skepticism that the two nations can generate sufficient funding, technological know-how, and political unity to pull off such a mission, citing earlier joint attempts, including a Martian mission:
In 2007, China and Russia signed an agreement for “joint Chinese-Russian exploration of Mars,” culminating in a 2011 launch of a Mars orbiter and landing craft. However, the Russian rocket malfunctioned, causing Russian and Chinese spacecraft to come crashing back down to Earth, an embarrassing conclusion to bothcountries’ first attempt to reach the red planet.
The two nations seems to be even more unified against the U.S. since this Foreign Policy article was published, so anything is possible. However, the U.S. did pretty well in the 1960s and 1970s after initially trailing the Russians, so my money is still on the U.S. in this latest race.
It did not take long for the newly-created U.S. Space Force to be the butt of jokes, but its mission is critical, as has already been noted in earlier postings on this site. Even so, a little bit of humor goes a long way, and the Netflix series Space Force has plenty of humor to go around. Season two starts Friday, February 18th. Here are trailers for season one and two.
Steve Carell is perfect as the leader of U.S. Space Force as it bungles along and eventually faces an international crisis on the moon. Mimicking reality, the U.S. and China have designs on the Moon and it may not be big enough for both nations. Given the accompanying cast, such as John Malkovich, Lisa Kudrow, and Ben Schwartz, you know this will be one strange space ride. Patton Oswalt will join the cast in season two as a bumbling astronaut, so things can only get more insane. Think of it as a combination of The Office and The Right Stuff giving birth to “The Wrong Stuff.”
We all need a laugh at the moment, so tune in and lighten up. After that, you can look into the work of the official U.S. Space Force and start worrying again.
Note: Here is the mission statement of the real U.S. Space Force (that word “Guardians” is really in there):
The USSF is responsible for organizing, training, and equipping Guardians to conduct global space operations that enhance the way our joint and coalition forces fight, while also offering decision makers military options to achieve national objectives.

Note: The real Space Force is protecting our satellites rather than running missions to the Moon, Mars, and Europa. TV shows have more latitude on such things.

Phys.org reported the success of a Chinese mission to retrieve a dead satellite, a hopeful sign given the increasing number of satellites and related debris in orbit. The story, “A Chinese space tug just grappled a dead satellite,” discusses how the Chinese spacecraft, Shijian-21, retrieved a dead navigation satellite belonging to the Chinese CompassG2 network. The story also included a video from ExoAnalytic Solutions demonstrating the retrieval and eventual release of the CompassG2 satellite into a graveyard orbit.
Of course, every pro comes with a con. Is this just a maintenance spacecraft or could it be part of a future offensive strategy to take other non-Chinese satellites out of orbit? The media in India were skeptical, as you can see from this headline: “China Preparing for War in Space?” Not that China is alone should it be looking for an anti-satellite spacecraft. Other countries, including the US, have similar dual-use spacecraft.
According to the Phys.org article, the Chinese have been silent, so the whole operation is somewhat opaque. Given the various attempts by other nations to solve the debris problem, it benefits each nation to share information on debris mitigation efforts so everyone can learn from them. Greater transparency from China would be nice.
