A robotic arm located outside of the International Space Station has been hit by orbital debris, but it's still functioning. 最近，空间站的一只机械臂被太空垃圾击中，不过仍然还能运转。  The impact to Canadarm2, first noticed by NASA and the Canadian Space Agency during a routine inspection on May 12, punched a hole in the arm boom and its thermal blanket. 5月12日，美国国家航空航天局和加拿大航天局在一次例行检查中首次注意到“加拿大2号臂”受到的撞击，将其臂架和隔热层撞出了一个洞。 "Despite the impact, results of the ongoing analysis indicate that the arm's performance remains unaffected," according to a release by the Canadian Space Agency. 加拿大航天局发布的一份报告称:“尽管受到了影响，正在进行的分析结果表明，该手臂的性能没有受到影响。” While the exact object responsible for this damage is unknown, the space station is at risk of impact from objects too small to be tracked as it orbits the Earth from 220 nautical miles away. 虽然造成这种损害的具体物体尚不清楚，但空间站在220海里外绕地球轨道运行时，由于物体太小而无法追踪，因此有可能受到撞击。 These tiny objects could be pieces of rock, micrometeorites, dust particles or even flecks of paint that chip off of satellites. 这些微小的物体可能是岩石碎片、微陨石、灰尘颗粒，甚至是卫星上脱落的油漆斑点。 About 23,000 objects about the size of a softball or larger are constantly tracked by space agencies to ensure that they don't collide with satellites or the space station. 目前大约有23000个垒球大小或更大的物体受到了航天机构的不间断跟踪，以确保它们不会与卫星或空间站相撞。  Protecting the astronauts living on the space station is crucial. 保护生活在空间站上的宇航员是非常重要的。 "NASA has a long-standing set of guidelines to ensure the safety of Station crew," according to the release. “美国航空航天局有一套长期的指导方针来确保空间站宇航员的安全，”新闻稿称。 "The safety of astronauts on board the orbiting laboratory remains the top priority of all Station partners." “确保轨道实验室上宇航员的安全仍然是空间站所有合作伙伴的首要任务。” The robotic arm is continuing to carry out planned operations as the analysis continues. 随着分析的继续，机械臂仍然在继续执行计划中的操作。 Orbital debris is also tracked to make sure there is no threat to spacecraft coming and going from the station. 轨道碎片也会受到跟踪，以确保进出空间站的航天器不会受到威胁。 On April 23, a SpaceX Crew Dragon Spacecraft carrying NASA astronauts Shane Kimbrough and Megan McArthur, French astronaut Thomas Pesquet of the European Space Agency and Akihiko Hoshide from Japan launched from NASA's Kennedy Space Center in Florida. 4月23日，太空探索公司搭载美国宇航局宇航员肖恩·金伯勒和梅根·麦克阿瑟、欧洲航天局的法国宇航员托马斯·佩斯凯和日本的星出彰彦的“龙”号飞船从美国宇航局位于佛罗里达州的肯尼迪航天中心发射升空。 En route to the station, the crew was actually warned when teams on the ground quickly realized the spacecraft might be at risk of colliding with a piece of orbital debris. 在前往空间站的途中，地面上的团队很快意识到宇宙飞船可能有与轨道碎片相撞的风险，机组人员收到了警告。 However, the danger passed when tracking revealed the object was farther away than anticipated. 然而，当追踪发现这个物体比预期的要远时，危险就解除了。 Although low-Earth orbit is more protective to the astronauts than if they were living in deep space, they are still exposed to some of the dangers of life in the space environment -- like orbital debris. 虽然近地轨道对宇航员的保护比住在深空更强，但他们仍然暴露在空间环境中的一些生命危险中——比如轨道碎片。 问题 文中提到了一名日本宇航员叫什么名字？ 留言回复正确答案，前五名朋友可以获得红包奖励哦，赶快来试试吧！ 感谢关注 跟Amber一起看世界 |
