跟随NASA的火星2020任务，或许是寻找火星上古生命迹象最具雄心壮志的一次。在2021年2月，飞船以约每小时1.2万英里的速度进入火星大气层，并将“毅力号”探测器降落到杰泽罗环形山的岩石地表上，这里是一个干涸的河流三角洲，科学家认为曾经可能孕育着生命。

Follow along as NASA launches the Mars 2020 Mission, perhaps the most ambitious hunt yet for signs of ancient life on Mars. In February 2021, the spacecraft blazes into the Martian atmosphere at some 12,000 miles per hour and lowers the Perseverance Rover into the rocky Jezero Crater, home to a dried-up river delta scientists think could have harbored life.

“毅力号”将搜寻该地区的生命迹象并采集样本，可能将其带回地球。机上载有一架四磅重的直升机，将进行一系列试飞——这是在另一个行星上的首次。在旅途中，“毅力号”还将测试能够从火星大气中产生氧气的技术，希望这种气体可以用作未来任务的燃料或供人类呼吸。

Perseverance will comb the area for signs of life and collect samples for possible return to Earth. Traveling onboard is a four-pound helicopter that will conduct a series of test flights—the first on another planet. During its journey, Perseverance will also test technology designed to produce oxygen from the Martian atmosphere, in hopes that the gas could be used for fuel—or for humans to breathe—on future missions.
