PayPal founder's rockets to reach Mars within two years
SpaceX plans to send an unmanned Dragon spacecraft to Mars as early as 2018, the privately owned company has said, a first step in achieving founder Elon Musk's goal to fly people to another planet.
US space agency 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.
SpaceX "could provide valuable entry, descent and landing data to NASA for our journey to Mars, while providing support to American industry," NASA said in a statement.
The announcement marks SpaceX's first target date for its unmanned mission to Mars.
The SpaceX programme is intended to develop technologies needed for human transportation to Mars, a long-term aim for Musk's privately held company, which is formally known as Space Exploration Technologies.
The company said it will provide details of its Mars programme 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.
The company recently has made space flight history by returning Falcon 9 rockets to landing pads on land and sea - key to Musk's quest to develop a relatively cheap, reusable launch vehicle.
SpaceX now flies cargo versions of its Dragon capsule to and from the International Space Station under a $2bn resupply services contract with NASA.
SpaceX is also upgrading the capsules to carry astronauts, with test flights to the station scheduled for 2017, under a separate NASA contract worth up to $2.6bn.
NASA does not plan to provide financial assistance to SpaceX's Mars mission.
The agency is investing in its own heavy-lift rocket, capsule and launch pad modifications targeting Mars travel.
By the time NASA expects to debut a test flight in lunar orbit with astronauts onboard in 2023, the agency will have spent about $24bn on the programme, an April 2016 US Government Accountability Office report shows.
In a sign of SpaceX's growing importance, the US Air Force on Wednesday awarded the company an $83m contract to launch a GPS satellite.
That broke the monopoly a Lockheed Martin and Boeing joint venture has held on military space launches for more than a decade.
The SpaceX Global Positioning System satellite will be launched in May 2018 from Florida, Air Force officials said.
The fixed-price award is the military's first competitively sourced launch service contract in more than a decade.
The Lockheed Martin-Boeing jv did not compete for the GPS launch contract, citing accounting issues, implications of trade sanctions limiting imports of its rockets' Russian-made engines and, according to a former ULA vice president, SpaceX's cut-rate pricing. (Reuters)
