Musk reveals when he hopes to launch mission crewed by robots to Mars

Elon Musk has said he wants to send a spacecraft crewed by humanoid robots on a voyage to Mars by the end of next year.

The tech billionaire outlined his latest schedule for Starship in a video presented at the project's Starbase home in Texas and posted online on Thursday.

The SpaceX founder had been set to give a presentation, called The Road to Making Life Multiplanetary, on Tuesday night, following a ninth test flight of the spacecraft earlier that evening.

But the speech was cancelled after the vehicle spun out of control about 30 minutes into the launch, having not achieved some of its most important test goals.

And on Wednesday, Musk confirmed his brief but tumultuous spell in the Trump administration as head of the Department of Government Efficiency (DOGE) was ending.

Musk warned there was no guarantee he would be able to meet the Starship timeframe he set out and much depended on overcoming a number of technical challenges, during flight-test development, especially a post-launch refuelling operation while orbiting Earth.

He previously said he aimed to send an unmanned vehicle to the red planet as early as 2018 and had targeted 2024 to launch a first crewed mission there.

Humans would land on Mars as part of the second or third flights, he said on Thursday, but the first trip would be in the hands of one or more humanoid Optimus design robots built by Tesla, the electric vehicle and battery maker he leads.

The current target to land a human on Mars using Starship is 2028, but it has yet to make an orbit of Earth.

Musk said he wants to make it so that "anyone who wants to move to Mars and help build a new civilisation can do so. Anyone out there. How cool would that be?".

At the end of 2026, Mars and Earth align around the sun, reducing the distance between the two planets to its shortest, but still seven to nine months' travelling time by spacecraft.

Musk said they had a 50-50 chance of meeting that deadline and if Starship isn't ready by then, SpaceX would wait another two years before trying again.

NASA, which hopes to land astronauts on Mars sometime in the 2030s, is planning to use Starship to return humans to the surface of the moon as early as 2027 - more than 50 years after the last lunar landings of the Apollo era.

Starship's previous test flights in January and March also failed, with the spacecraft exploding moments after lift-off, raining debris over parts of the Caribbean and forcing scores of commercial jets to change course as a precaution.

Musk shrugged off the latest mishap on Tuesday with a brief post on X, saying it produced a lot of "good data to review" and promising a faster launch "cadence" for the next several test flights.
