China Will Bring Back Samples of Mars Before the U.S., Tianwen 3 Mission Goes Up in 2028
The China National Space Administration (CNSA) announced the Tianwen 3, a daring Mars sample return mission to launch in 2028.

For several years now the biggest space agencies in the Western world have been struggling to get going the Mars Sample Return mission, perhaps the most ambitious robotic space mission ever undertaken. But, while the West struggles, China has just declared its intention to be the first to bring back samples of the alien planet.
America’s and Europe’s
Mars Sample Return is so tricky to pull off that it doesn’t even have an official launch date anymore. On the table since the late 2000s, it has been postponed time and again, to the point where no one is hopeful anymore that it will get going before the 2040s.
The last time NASA said anything about this project was at the beginning of last year, when it gave us a look into the different approaches it would need to follow to be successful. No matter the path forward, it relies on several key elements being developed and working in perfect sync: a vehicle on the surface to collect the samples, another one to pick them up, an ascent vehicle to deliver them to Martian orbit, and a spacecraft to bring them back to Earth.
Of all that, only the vehicle tasked with collecting samples is already on Mars, and that’s only because NASA recently repurposed its newest rover, the Perseverance, to perform this duty. All the others are still on the drawing board, with no start of construction in sight.
China, on the other hand, is so close to realizing all the hardware it needs for a sample return mission that it announced at the end of last week it should be ready to get going as soon as 2028, with the return of the first samples of the Red Planet possible as soon as 2031 – that’s about a decade before the West’s mission even departs!
The Asians’ effort is called the Tianwen 3, and it is not a walk in the park either, as it too includes a number of elements that have to work perfectly. More to the point, we’re dealing with five distinct bits of hardware: a lander, an ascender, a service capsule, an orbiter, and a reentry module.
As you can see, the
China National Space Administration (CNSA) says nothing about a robot meant to actually collect the samples, meaning that either they keep it a secret for the moment, or the lander itself will be tasked with collecting them from its landing site – in which case we will be faced with an entirely different approach from that of the Americans, and potentially much less rewarding in terms of potential finds.
At the end of last week, China marked its 11th Space Day, and, during an event held in Chengdu, we were given a glimpse at some of the instruments the Tianwen 3 mission will carry with it to Mars. There are five of them, made both in China and by international partners.
The Tianwen 3 orbiter, which is the element that stays in orbit around planet Mars as all the excitement unfolds on the ground, will be equipped with four of the five instruments that were announced.
The first is the Mars PEX Spectrometer developed by the Panel on Exploration of the international science organization Committee on Space Research, which will be used to search from high up traces of life on the surface, but also to detect the composition of surface minerals.
The second instrument on the orbiter is the Mars Molecular Ion Composition Analyzer, the work of the Macao University of Science and Technology, which has been designed to monitor the escape process of the Martian atmosphere.
Up next is the Laser Heterodyne Spectrometer from the Chinese University of Hong Kong, which will
“detect the vertical profile distribution of water isotopes in the Martian atmosphere and measure Martian wind fields.”
Last but not least, the Mars Terrestrial Hyperspectral Imaging Spectrometer, imagined by the same peeps over at the University of Hong Kong, will be used to detect life traces, water-bearing minerals, and conduct general resource surveys.
Finally, the lander will bring down to the surface a laser retroreflector array developed by Italy's National Institute for Nuclear Physics, the National Laboratory of Frascati, which will deploy precise reference points on the Martian surface.
The CNSA says the Tianwen 3 mission will lift off two years from now, aided by no less than two
Long March 5 heavy-lift carrier rockets that will take off from the Wenchang Space Launch Center in Hainan province. Three years after that, the Martian samples are expected to be returned to Earth by means of the re-entry module, marking the first time in the history of space exploration that China beats the U.S. at something that truly matters.
