Tianwen-2, a Chinese space mission, is set to embark on a two-and-a-half year journey to the asteroid Kamoʻoalewa, aiming to collect samples. This mission is shorter than similar missions like Japan's Hayabusa 2 and NASA's OSIRIS-REx. The spacecraft will employ various sampling methods, including a robotic arm, a touch-and-go maneuver, and an innovative anchor-and-attach technique to secure itself to the asteroid's surface. After collecting samples, Tianwen-2 will return to Earth in late 2027, where scientists will analyze the specimens for their physical and chemical properties.
Tianwen-2's mission to Kamoʻoalewa aims to collect asteroid samples using innovative methods, with a total duration of only two-and-a-half years, significantly shorter than previous missions.
The spacecraft’s sampling techniques include a robotic arm, a touch-and-go maneuver similar to Hayabusa 2, and an anchor-and-attach method to secure itself to the asteroid.
