China's Tianwen-3 mission is planned for launch around 2028 and is expected to return Martian samples to Earth around 2031, potentially becoming the first Mars sample-return mission in human history. Its primary scientific goal is to "search for traces of potential life on Mars." 中国天问三号计划于2028年前后发射，2031年前后携火星样品返回地球，有望成为人类历史上首个火星取样返回任务，“探寻火星潜在生命痕迹”是其首要科学目标。 #China# #看中国#
