【科技报道】美国宇航局的火星2020年为人类进入深空做准备 NASA's Mars 2020 to Prepare for Humans into Deep Space

America's space agency is nearing completion of a vehicle that will search for evidence of past life on Mars. It is too cold and dry for life to exist on the surface of Mars today. But scientists hope the rover will find evidence of life that once lived on the planet.


美国太空总署即将完成一项寻找火星前世证据的飞行器。今天太冷了,太干燥了,无法生存在火星表面。但是科学家希望这辆流浪者能够找到曾经生活在地球上的生命的证据。


The rover will make the trip to the red planet later this year, and start preparing for NASA's mission to send humans into deep space.


这辆流浪者将在今年晚些时候前往这颗红色星球,并开始为NASA将人类送入深空的任务做准备。


NASA recently showed off its Mars 2020 rover. It has four wheels and is about the size of a car. The rover will be sent to Florida's Kennedy Space Center in three parts. It will be put together there. The vehicle's official name will be chosen soon.


NASA最近展示了其“火星2020”火星探测器。它有四个轮子,大约相当于一辆汽车的大小。流动站将分为三部分送往佛罗里达州的肯尼迪航天中心。它将被放在那里。车辆的正式名称将很快被选择。


Launch is set for July. The following February, the rover will land in the 250-meter-deep Jezero Crater – a dry lake bed that is bigger than New York's Manhattan. Billions of years ago, it was a deep lake, but as the climate changed there, it dried up. Scientists believe that the crater holds many sediments in great condition—some may be 3.5 billion years old. They hope the rover will find fossils—remains of plants or animals that once lived on Mars.


发射定于七月。接下来的2月,这辆火星车将降落在250米深的Jezero陨石坑中-这是一块干燥的湖床,比纽约的曼哈顿大。数十亿年前,它是一个深湖,但是随着气候的变化,它干dried了。科学家认为,该火山口将许多沉积物保持良好状态,其中一些沉积物可能存在35亿年之久。他们希望流浪者能够找到化石-曾经生活在火星上的动植物遗骸。


"The trick, though, is that we're looking for trace levels of chemicals from billions of years ago on Mars," Mars 2020 deputy project manager Matt Wallace told Reuters. The rover will collect up to 30 samples, or small amounts, of soil. NASA plans to have them picked up and returned to Earth by a future spacecraft.


“不过,诀窍在于,我们正在寻找数十亿年前火星上痕量的化学物质,” 2020年火星项目副经理Matt Wallace告诉路透社。流动站将收集多达30个样品或少量土壤。美国宇航局计划让他们将它们捡起来,并由未来的航天器送回地球。

Mars 2020 research will also be very important for future human missions to the red planet. It is carrying equipment that can turn carbon dioxide, which is everywhere on Mars, into oxygen for breathing.


2020年火星研究对于未来人类对红色星球的飞行任务也将非常重要。它所携带的设备可以将火星上无处不在的二氧化碳转化为氧气供呼吸。


If successful, Mars 2020 will mark NASA's fifth Martian rover to carry out a soft landing. Important lessons were learned from the most recent Curiosity rover, which landed on the planet's surface in 2012. It continues to move and work on the Martian surface southeast of the Jezero Crater.


如果成功,“火星2020”将标志着NASA的第五次火星探测器进行软着陆。从最近的好奇号流浪者那里学到了重要的教训,该流浪者于2012年降落在地球表面。它继续移动并在Jezero Crater东南的火星表面上工作。


The former Soviet Union is the only other country to land a rover on Mars. But it did not deploy. China and Japan have attempted to send orbiters around Mars. India and Europe's space agency have successfully sent an orbiter to the planet.


前苏联是唯一一个在火星上流浪者的国家。但是它没有部署。中国和日本已尝试将火星送入火星。印度和欧洲的航天局已经成功地将一颗人造卫星送入了地球。
