Moon Rising Between Starships

Explanation: What’s that on either side of the Moon? Starships. Specifically, they are launch-and-return reusable rockets being developed by SpaceX to lift cargo and eventually humans from the Earth’s surface into space. The two rockets pictured are SN9 (Serial Number 9) and SN10 which were captured near their Boca Chica, Texas launchpad last month posing below January’s full Wolf Moon. The Starships house liquid-methane engines inside rugged stainless-steel shells. SN9 was test-launched earlier this month and did well with the exception of one internal rocket that failed to relight during powered descent. SN10 continues to undergo ground tests and may be test-launched later this month.

星舰之间的月出

说明: 月亮二侧的物体是什么?星舰!具体来说,它们是太空探险公司的发射与可再回收使用火箭,目前用在运载货物,不过未来也会把人员从地球表面载送到太空。从美国德州博卡奇卡村的发射台附近看出去,上个月的满月(狼月)下方的这二艘火箭,编号分别是SN9(序列号9)与SN10。这些星舰是由数部液态甲烷引擎,以及外面包覆的不锈钢外壳所组成。在这个月稍早的发射测试中,SN9的表现相当出色,只有在返回时,它的一部引擎并未遵循指令重新点燃。SN10目前持续在进行地面测试,在这个月底,或许也会进行发射测试。
