Elon Musk on Saturday announced that SpaceX's Starship Mars will be carried out by the end of 2026. After a success, the company will focus on human landing on Mars by 2029-2031.

Elon Musk says SpaceX will go to Mars at the end of 2026 with Tesla's Optimus, a humanoid robot. If all goes well, humans could be headed to the red planet in 2029, Musk says.

Musk—who has a history of setting unrealized goals for his companies—says he wants to send humans to Mars by 2029, though he says 2031 may be more likely.

SpaceX aims to launch Crew-10 on Friday. The crew-swap mission will enable NASA’s Butch Wilmore and Suni Williams to return home from the International Space Station.

The replacements for NASA’s two stuck astronauts launched to the International Space Station on Friday night, paving the way for the pair’s return after nine long months. Butch Wilmore and Suni Williams need SpaceX to get this relief team to the space station before they can check out.

SpaceX's Crew-10 mission has successfully launched from NASA's Kennedy Space Center in Florida at 7:03PM Eastern on March 14. NASA astronauts Anne McClain and Nichole Ayers, Japan Aerospace Exploration Agency's Takuya Onishi and Roscosmos cosmonaut Kirill Peskov are onboard and will join the ISS crew after the spacecraft docks with the orbiting lab at 11:30PM Eastern time on March 15.
