美发射猎鹰9号火箭 首次将超级计算机送上外太空

2017-08-15 08:14:38   中国网

当地时间8月14日中午12时31分,美国肯尼迪航天中心成功发射“猎鹰9号”火箭,并首次将超级计算机送入外太空。

肯尼迪航天中心官网宣布,美国太空探索技术公司(SpaceX)火箭载着“龙飞船”于佛罗里达州卡拉维拉尔角(CapeCanaveral)发射升空。火箭不仅为美国宇航局(NASA)将首台超级计算机和三套科学实验设备送往国际空间站(ISS),还搭载着一枚美国军用成像卫星。

经几天绕轨飞行,火箭计划于17日与国际空间站进行对接。之后,首台进入外太空的超级计算机将进行长达一年的高速运行实验,执行一系列基准测试,观测系统性能。

美国彭博新闻网消息称,这是一项由NASA和惠普公司共同进行的超级计算机实验,旨在为人类前往火星作准备。

这台名为“SpaceborneComputer(太空计算机)”的超级计算机由惠普公司研发。运行Linux系统。惠普公司介绍,他们将检验未经特别“加固”的超级计算机能否在外太空正常运行。

据知,惠普公司对“Spaceborne”进行了软件的水冷“加固”处理,但未根据外太空失重环境作硬件方面的物理设计。该公司指出,计算机的水冷“加固”方式能实时管理计算机系统,减少环境诱发错误。该技术通过了至少146项安全测试和认证,才获得NASA批准进入外太空。

据知,由于当前太空探索的大量数据需要传回地面进行处理。而火星与地球之间的一次数据传输需耗时40分钟,这必然成为人类登上火星进行探索的安全隐患。

换言之,美国启动外太空超级计算机的运行实验,是外太空实时数据处理的实验基础,是人类迈向火星的重要一步。

值得一提的是,这是今年“猎鹰9号”完成的第11次火箭发射任务。火箭发射升空9分钟后,主要飞行设备垂直返回到硬地面。这也是美国太空探索技术公司(SpaceX)第9次成功在硬地面回收火箭。

该公司计划近两年来加快了火箭发射实验的速度,意在更快实现人类登上火星的目标。据知,该公司将于11月首次试射猎鹰9号重型火箭。
