China’s Tianwen 3 Mars sample-return mission ‘a Sputnik moment’
China aims to launch the Tianwen 3 mission in 2028 to bring back roughly 500 grams of Martian soil by 2031, per the China National Space Administration. Former NASA 'Mars Czar' Scott Hubbard told Space.com that if the timeline holds, it represents a Sputnik moment — a milestone that could see China become the first to find evidence of life beyond Earth.
Bottom line — A former NASA official says China may beat the US to the first extraterrestrial life evidence.
