It’s the next distant mission yet The first exploration of Mars is underway. – On the Red Planet, China is aiming for a new and very complex technical goal: automated sample collection. So far, the Chinese Space Agency, CNSA, (end of 2020). It’s the only mission of this kind undertaken by China, but it is truly amazing.
A type of asteroid that has never been explored
After Tianwen-1, the Tianwen-2 mission will leave in 2025 in order to and the sound Indicates that it will be a previous projectile of . This is called the Earth’s semi-satellite: it revolves around each of the But also around our planet – in a very elliptical way.Kamwalwa (Also known as 2016 HO3), reaching only 40 meters in diameter. It’s an asteroid whose
Kamo’oalewa is known as Earth’s most stable semi-synthetic moon. In fact, these things are on fragile paths and can branch off under the influence. The asteroid is expected to remain in its orbit for another 300 years. Nothing of this kind has been approached. Collecting samples with Tianwen-2 will allow us to learn more about Earth’s quasi-satellites and their origin.

Sample collection from Kamo’oalewa must be completed and returned to Earth very quickly. The journey to the asteroid will only take a few months. CNSA will use technology Touch and go (landed – picked up – left), formerly used by Japanese missionsor subordinate . Only the installation technology is different: Tianwen-2 will spread four arms which will screw on the surface. This will prevent the probe from leaving the surface during sampling because due to its size, the asteroid’s gravity can be considered zero. The CNSA has not specified how many Tianwen-2 samples it is supposed to return to Earth.
Once sampling is complete, the probe will return to return the samples to Earth. You’ll drop it into a capsule protected by a heat shield to pass throughthat will fall under In the from Inner Mongolia two to three years after take-off in 2025. But at this point, the Tianwen-2 mission will not be completed. She has a second destination.
After dropping the Kamo’oalewa samples to Earth, Tianwen-2 will continue on its way toward Object 311P/Panstarrs. The trip will last seven years. When Tianwen-2 passes through the Earth, it will use its gravity to accelerate and thus save fuel. Once we reach the 311P/Panstarrs, the probe will tell us all the information about this strange object. Ranked for the first time in the categoryit is actually an “active asteroid”, that is, it combines the properties of both an asteroid and a comet.
Conquer China’s Solar System
On May 13, CNSA The mission leaves the conception stage and moves to the development stage. We will first build engineering models of various Tianwen-2 components for testing before building flight models for takeoff in 2025.
CNSA has already identified the following tasks in the Tianwen Program. After returning the asteroid samples with Tianwen-2, the agency will deal with the extreme difficulty of returning the Mars samples with Tianwen-3. It will be an all-in-one task, On the contrary NASA and . Takeoff is scheduled for 2028. The Tianwen-1 probe, currently in orbit around Mars, continues its surface mapping work to find the best sampling site.
