SpaceX to Send Five Uncrewed Missions to Mars by 2026

SpaceX CEO Elon Musk announced on his social-media site X on Sunday that the company plans to send five uncrewed Starships to Mars within the next couple of years. Musk said the company has to wait for the next Earth-Mars launch window before sending the missions. These windows occur when Mars and the Earth are lined up in such a way that flights between them take the least amount of energy and time. The next window is in 2026. Should SpaceX miss the deadline for that time period, the next launch window is late 2028 into early 2029. 

Should the uncrewed ships land safely, Musk anticipates sending crewed missions to Mars during the 2028-29 launch window. If the tests don’t succeed, the company will try uncrewed missions again in the 2028 launch window and push the crewed missions back to the launch window after that.  

“No matter what happens with landing success, SpaceX will increase the number of spaceships traveling to Mars exponentially with every transit opportunity,” Musk said on X. 

The ultimate goal, according to Musk, is the building of a self-sustaining Martian city in “about 20 years.” SpaceX president Gwynne Shotwell echoed those claims two years ago in an interview with CNBC. 

A representative for SpaceX did not respond to a request for comment. 

SpaceX has challenges ahead

Musk has been known to move the target when it comes to SpaceX’s timeline on getting ships to Mars. Musk famously said that SpaceX would be sending ships to Mars in 2024 but that was four years ago. SpaceX has been dealing with numerous issues, including run-ins with the FAA due to procedural issues and fights with regulators over the environmental impact of the company’s launches. 

Musk touched on those issues in his tweet, saying that one of his biggest concerns “is that the Starship program is being smothered by a mountain of government bureaucracy that grows every year.” Musk blames “stifling red tape” for SpaceX’s inability to launch missions to Mars sooner. 

SpaceX is facing delays in other sectors as well. NASA’s Artemis III mission, which is using SpaceX’s Starship, was originally scheduled for 2025 and has been pushed back to 2026. It’ll be the first crewed mission to the moon in half a century when it does eventually happen. Per Reuters, Japanese billionaire Yusaku Maezawa canceled his flight around the moon that was also slated to use SpaceX’s Starship.
