Tianwen-3 (Chinese: 天问三号) is a planned Mars sample-return mission by China which would send two spacecraft (an orbiter/Earth-returner and a lander/ascent-vehicle) via two separate launches to Mars. Together, the two spacecraft will seek to obtain samples of Martian rocks and soil and then return the cached samples to Earth.[1] The mission is scheduled to launch in 2028.[2]
