   Explanation: What's that on either side of the Moon? [4]Starships.
   Specifically, they are launch-and-return reusable rockets being
   developed by [5]SpaceX to lift cargo and [6]eventually humans from the
   [7]Earth's surface into space. The two rockets pictured are [8]SN9
   (Serial Number 9) and [9]SN10 which were captured near their [10]Boca
   Chica, [11]Texas launchpad last month posing below January's full
   [12]Wolf Moon. [13]The Starships house [14]liquid-methane engines
   inside rugged [15]stainless-steel shells. SN9 was [16]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 [17]ground tests and may be test-launched later this month.
