The car-sized, six-wheeled rover, nicknamed Percy, is the US space agencys bigge
11、st and most advanced explorer to date. Its primary mission is to search for signs of ancient microbial (微生物的)life on Mars.Landing on Mars is extremely tricky. The Red Planets gravitational (弓I 力的)pull causes approaching spacecraft to go faster to high speeds, while its thin atmosphere-just 1 percent
12、 that of Earthsdoes little to help slow it down as it approaches the surface.The scientists had to reduce Percy*s 12, 000 mph speed to a safe landing speed of less than five mph一in just six and a half minutes. The target entry angle also had to be a precise 12 degreesany steeper, and the spacecraft
13、would burn up; any flatter, and it would get lost in space. It is no wonder that the final approach is often referred to as the seven minutes of terror”.Upon attaining a manageable speed, Percy briefly flew over the Martian surface to seek out the prefect landing spot. Its complex map-reading system
14、 rapidly scanned the area and matched it with maps in its database to find the best location.The NASA scientists will spend the next two months testing Percys scientific instruments. Once ready, the rover will begin to carry out its mission.Perseverance is the smartest robot ever made, but confirmin
