Osiris-Rex

Osiris-Rex was the first space probe sent to an asteroid to gather samples for Earth. On 8 September in 2016, it was launched on its journey to the 101955 Bennu asteroid. (PROSE: Time Traveller's Diary)

Behind the scenes
Although OSIRIS-REx is described in Time Traveller's Diary as being the first asteroid sample-return mission in the DWU, in real life, it was actually the third after Hayabusa and Hayabusa2.
