Our aspirational goal is to send our first cargo mission to Mars in 2022. … A second mission, with both cargo and crew, is targeted for 2024.

SpaceX's own Mars page, following the BFR update "Making Life Multiplanetary" at the International Astronautical Congress in Adelaide. Previously filed here under the 2016 IAC talk in Guadalajara, which was a different presentation.
What happened: Nothing has been sent to Mars. Starship flew its thirteenth test on 24 July 2026, deploying 20 Starlink V3 satellites on a deliberately suborbital trajectory, and has yet to fly an orbital mission with an operational payload.
