Exploration

Rimae Atlas was supposed to be the landing place of the Hakuto-R Mission 1 by ispace, that launched on 11 December 2022. Separating from the rocket 47 minutes later at a distance approximately 970 kilometres (600 mi) from Earth,[6] it crashed on 16:40 UTC (00:40 JST) on 25 April 2023.[6]
