Leonardo (rover)
From Tardis Wiki, the free Doctor Who reference
Leonardo was a European Space Agency rover on Mars in the 2020s.
On 31 December 2020 to 1 January 2021, Leonardo spotted a CD of David Bowie's "Life on Mars". John Wilcox assumed this was a New Year prank that was recorded with one of the test rovers in Arizona, but the CD was actually left on Mars by Erimem. (PROSE: Life on Mars on Mars)
