China’s March to Mars

People want to go to the Red Planet, including China. The United States has sent many spacecraft there, as have India and the European Space Agency. Early in the history of the Space Race, the then-Soviet Union mounted an ambitious campaign to get swarms of spacecraft to the Red Planet. A few of their spacecraft did get there and return a little data, but that was about it. Most others failed. As did missions from the U.S. and other countries. But, for the most part, the exploration of Mars has been a largely American concern.

Of course, many of us have heard that Elon Musk wants to send a population of people to Mars. That will start as soon as he’s able to marshall all the resources. His missions could happen in the next decade. We’ll have to wait and see what happens next with SpaceX’s intentions toward the fourth planet.

China and Mars

Of course, China has its eyes on Mars these days. The Chinese National Space Agency has sent one mission to the Red Planet. That was the Yinghuo-1 probe that accompanied the Russian Fobos-Grunt sample return spacecraft. Yinghuo-1 was supposed to orbit Mars while its partner studied the moon Phobos. However, the mission failed not long after launch from Earth in 2011. A few months later, in 2012, Yinghuo-1 deorbited into Earth’s atmosphere and disintegrated.

Despite that inauspicious beginning, China has solid plans for going to the Red Planet. It recently showed off its Mars Global Remote Sensing Orbiter (with Rover) headed for Mars this summer. And, late last year, it tested its most powerful rocket, called Long March-5. This heavy-lift rocket took a large satellite to orbit and ultimately can be used to send along China’s Mars orbiter on its way.

The Mars mission is reported to have a cost of about $39 million (in U.S. dollars). It’s the first of several that will bring China to parity with the U.S. in terms of Mars remote exploration.

Crewed Missions to the Red Planet

Will China want to send people to Mars? That’s an interesting question. They haven’t played that card publicly yet, but I wouldn’t be surprised if eventual human exploration isn’t on their agenda. The Chinese have built a Mars simulator training area in the Gobi desert, called Mars Base 1. It serves the same function (to give astronauts a taste of what living and work on Mars is like) that other bases in Utah, Canada, and Antarctica have done for NASA explorers. Check out more about the Gobi desert camp in this video.

China and Near-Earth Space

As I mentioned in my last article, China has robust plans for human exploration of near-Earth space. The country has sent humans to space and certainly wants to get a crewed space station up and running. China will be testing a next-generation crew spacecraft this year. This will be useful for transporting both people and goods up to the new space station in the Tiangong program. It is already testing on the design of the main body of the station, which will advance those plans even further.

Where China goes—as in, working on a trans-Mars ship, exploring a near-Earth asteroid (as it has plans to do), is an interesting discussion. It also plans a possible probe out to the gas giant Jupiter, is all in the future beyond 2020. At the moment, China has signaled interest in resuming talks with the United States. Not just about trade, but also on areas of mutual concern in space exploration. And, there has been some collaboration between the U.S. and Chinese scientists on the lunar-based Change’-4 mission when it landed. China has indicated for years that it is open to collaboration on more science with anyone who will cooperate with it.

In the meantime, the Chinese National Space Agency has a good blueprint for exploration. It continues working on its future missions to near-Earth space, the Moon, Mars, and beyond.

Going to Space

I spent this morning watching a spacewalk by a pair of American astronauts. They were doing some work on the International Space Station. It’s the sort of “common” work that, in a few decades, will be “the daily grind” for people living and working in space. As I write this, I’ve got the HDEV camera view of Earth floating by on my second monitor, approximating the “Overview Effect” from my office.

In a very short time (compared to the length of human history), we’ve gone from being land-based beings to space explorers. To be sure, we’ve only gone to space between here and the Moon (and, of course, TO the Moon, 50 years ago). But, we’ve opened up space exploration for all kinds of people. There are a bunch of them passing overhead various bits of Earth’s surface every hour and a half. The International Space Station represents the first and best example of international cooperation of space explorers in our history. It has hosted hundreds of astronauts from around the world. They go up, they do work, they live in space, and after a time, they come back to Earth to continue their work.

“Little Kid” Spacewriter would find all this hard to believe. She began looking to the stars during the Apollo mission build-up. She dreamed of being an astronaut, like so many other kids since then. I once got a letter from a young lady in Zimbabwe when I was a graduate student, looking for information about NASA. She proudly informed me that she wanted to work at NASA and fly to space. I sent along information and encouragement because, to me, anybody’s dream of going to space should be encouraged. I do mean everybody.

China and Space Exploration

That brings me to China and the China National Space Administration (CNSA). I haven’t written a lot about Chinese space ambitions, and it’s high time I took a closer look at their projects.

I did some work with a science and technology museum in Shanghai as a content advisor a year or so back. It was mostly about astronomy and space exploration for exhibits. I was anxious to learn as much from our Chinese colleagues about their space program as I could share from them about ours. My counterparts were quite surprised that I was interested in it. I shared a copy of my book Space Exploration: Past, Present, and Future. It contains a general look at the Chinese space program.

They’re quite proud of their program. And why not? Many I talked to are as space-mad as I am. Their county is doing something cool and exciting. It was an interesting time and we all enjoyed sharing what we knew about space exploration.

The country’s program is a pretty robust one. The CNSA is responsible for all launches (satellites and other payloads). It also coordinates with private launch services (which DO exist in the country). China has its own fleet of satellites for various functions, as well as a rocket program built to further its ambitions in space.

China to Space

So, what’s China doing in space these days? Let’s take a look at some highlights. In late December, for example, CNSA launched its largest carrier rocket, the Long March-5. It is the workhorse “heavy lifter” of the country’s rocket program. Of course, the Chinese take great pride in their work and are rapidly becoming the third-largest space power. Like the U.S., Russia, and others, they continually test their rockets and other hardware, usually with great success.

To Near-Earth Space Orbit and the Moon

In recent years, among its other space aims, the Chinese program has focused on activities on the Moon. Its Chang’e-4 lander and rover are studying the lunar far side and have been doing so since 2018. It will be joined by Chang’e-5 later this year. I previously wrote about the Chang’e-3 lander and its successful lunar landing. The new mission will work on several tasks, including gathering up samples of lunar soil. Eventually, they’ll be brought back to Earth for study.

But, that’s not all that China wants to do in space. You’ve probably heard about their space station, Tiangong. Tiangong 2, the latest version of their station, deorbited in 2018. A new modular space station is planned for low-Earth orbit. Crucial parts are headed to space starting later this year as part of the Tiangong program. The large core module called Tianhe (which means “Harmony of the Heavens” in Mandarin) is first. Other pieces will be added on, later. They include an experiment module (for science research) called Mengian (“Dreaming of the Heavens”). There is also Wentian, another experiment module. Its name means “Quest for the Heavens”. Finally, there is also a space telescope associated with the station, called “Xuntian” (“Heavenly Cruiser”).

To support the construction, China has been testing its Long March rocket family, which will be used to loft bits of the station into orbit. Here’s a good video that covers much of China’s intentions for the near future in space.

Beyond Near-Earth Space?

China also has set its aim on Mars and other parts of the solar system. I’ll write in more detail about its Martian ambitions in my next entry. And, they aren’t the only ones reaching out to the stars. In all, when I was writing my book, I counted 72 countries (at the time of writing) with space programs or startups in space exploration. Spacefaring activities are no longer limited to the “big kids” club here on Earth. Nor should they be. Humanity’s future IS in the stars. After all, the stars are where we came from, long ago.
