SpaceX plans to send an unmanned Dragon spacecraft to Mars as early as 2018.
The announcement was made on Twitter today and is a first step in achieving founder Elon Musk's goal to fly people to another planet.
If SpaceX is successful, it will beat all other world space agencies in landing a new robot on Mars. Nasa, which is aiming for a human mission to Mars in the 2030s, said it will provide technical support for SpaceX's first foray, known as Red Dragon.
The company said it will provide details of its Mars program at the International Astronautical Congress in September.
'Dragon 2 is designed to be able to land anywhere in the solar system,' Musk posted on Twitter.
'Red Dragon Mars mission is the first test flight.'
He said that with an internal volume about the size of a sports utility vehicle, the Dragon spacecraft would be uncomfortable for people making the long journey to Mars.
Musk, a billionaire entrepreneur who helped to found Tesla Motors and PayPal, started SpaceX in 2002 with the goal of slashing launch costs to make Mars travel affordable.
SpaceX intends to debut its Mars rocket, a heavy-lift version of the Falcon 9 booster currently flying, later this year.
