The results of their search for water-bearing minerals on Utopia Planitia in the northern lowlands of Mars were reported in Science Advances in May.
他们在火星北部低地的乌托邦平原上寻找含水矿物的结果发表在5月份的《科学进展》杂志上。
Landing a spacecraft on the surface of Mars is one of the hardest things to do in planetary exploration. Due to the red planet’s low atmospheric pressure, the spacecraft needs to be slowed down around 7 minutes before touching the ground – and do so on its own because it is too far away to receive instructions from the Earth in time.
在火星表面着陆宇宙飞船是行星探测中最困难的事情之一。由于这颗红色星球的低气压，航天器需要在触地前减速约7分钟，而且要自己减速，因为它距离地球太远，无法及时收到来自地球的指令。
China and the United States are the only countries to have landed a spacecraft on Mars, and Tianwen 1’s touchdown prompted calls for collaboration between the space nations.
中国和美国是世界上仅有的两个在火星上着陆过航天器的国家，“天问一号”的着陆激起了这两个太空国家之间合作的呼声。
Asked in Paris about cooperation with China, Nasa administrator Bill Nelson reportedly said it was “up to China” and there needed to be openness and transparency from the Chinese side.
据报道，美国宇航局局长比尔·纳尔逊在巴黎被问及与中国的合作时表示，这“取决于中国”，中国方面需要公开和透明。
However, Nasa is not allowed to cooperate with China because of the Wolf Amendment, a US law that has been in place since 2011 to prevent the agency from working with Chinese commercial or government space agencies on a bilateral basis.
然而，由于《沃尔夫修正案》(Wolf Amendment)，美国宇航局不被允许与中国合作。《沃尔夫修正案》是美国自2011年开始实施的一项法律，旨在阻止Nasa与中国商业或政府太空机构在双边基础上合作。
China does not have any law prohibiting cooperation with other spacefaring nations. Three European instruments went up on the Chang’e 4 mission and last week, the CNSA reached an agreement with the United Arab Emirates to help release their Rashid II rover during the Chang’e 7 mission to the moon’s southern polar region around 2026.
中国没有任何禁止与其他航天国家合作的法律。三个欧洲仪器在嫦娥四号任务中升空，上周，中国国家航天局与阿拉伯联合酋长国达成协议，在2026年左右嫦娥7号前往月球南极地区的任务期间，帮助释放他们的拉希德2号月球车。
China and the US are pushing ahead with their own missions to bring back rocks from Mars, possibly as early as 2031.
中国和美国正在推进各自从火星带回岩石的任务，最早可能在2031年。
中国和美国谁会最早将火星岩石样板带回地球？
The IAF is a non-governmental organisation established in 1951 to promote and coordinate global space activities, with members from major space agencies, companies, and research institutions worldwide.
国际宇航联合会是一个非政府组织，成立于1951年，旨在促进和协调全球空间活动，成员来自世界各地的主要航天机构、公司和研究机构。
The federation launched the World Space Award in 2013 to recognise a “most eminent person or team” who has made “an exceptional impact” to the progress of the world space activities.
