行星科学家们正在为下一代火星车寻找既安全又有科学价值的着陆地点,但是资料显示恐怕鱼和熊掌不可得兼。第一次发射火星着陆探测器时,不可避免地看上去更像是扔标枪。对于1977年的“海盗”号而言,当时没有人知道火星上哪里是安全的、哪里又是有探测价值的。但是现在不同了,在5次安全地着陆火星之后,再加上传回的几万亿字节的数据, Planetary scientists are looking for safe and scientific landing sites for the next generation of rovers, but the data show that there is a scarcity of fish and bear’s paw. When launching the Mars Landing Launcher for the first time, it inevitably looks more like a javelin throw. For the 1977 pirate, no one knew when it was safe on Mars and where it was probing. But now it’s different, after five safe landings on Mars, plus the trillions of bytes of data that is returned,
