NEW YORK — Space Exploration Technologies () announced plans April 5 for a new heavy-lift rocket, a vehicle that would be the most powerful commercial rocket ever built and haul much heavier loads than the company’s previous boosters.
The new unmanned rocket, called a Falcon Heavy, would be able to loft about three times the amount of mass carried by SpaceX’s current Falcon 9 boosters on missions to low Earth orbit. “This is a rocket of truly huge scale,” SpaceX founder and Chief Executive Elon Musk said during a press conference at the National Press Club in Washington.
The new rocket would be able to carry about 53,000 kilograms of cargo to orbit — about twice the payload-carrying capability of the space shuttle. The Falcon Heavy would launch more than twice as much weight as the4 heavy, currently the most powerful rocket in operation. Only NASA’s Saturn 5 Moon rocket, which last launched in 1973, could carry more cargo to orbit, SpaceX officials said.
Musk said the rocket should lower the launch cost of cargo to about $1,000 per pound, about one-tenth the cost per pound on NASA shuttle launches.
“Falcon Heavy sets a new world record for the cost per pound to orbit,” Musk said. “That’s a pretty huge leap in capability.”
The price for a launch aboard the new Falcon Heavy is set for $100 million, compared with the $50 million price tag for a Falcon 9 liftoff, Musk said. To maintain that pricing, SpaceX would need to launch the Falcon Heavy four times a years, he said.
Musk said the company is “at an advanced stage of discussions” with U.S. government and commercial customers.
The first launch of the new heavy-lift rocket could come as early as 2013, Musk added. SpaceX has no customer lined up for the first flight, a demonstration launch the company plans to conduct at its own expense from California’s Vandenberg Air Force Base.
SpaceX’s next giant leap
The development of a heavy-lift vehicle is yet one more foray for the quickly growing commercial space firm, which hopes to play a vital role in American space activities in the decades to come.
Musk said the heavy-lift vehicle is designed to human-rating standards and could potentially carry humans to space. Given its strength, the rocket could even be used to send people to the Moon or Mars, Musk said, though such missions would likely require multiple launches to send various components (such as the lander and the return vehicle) separately.
“It can launch people if need be and do so safely,” Musk said of the Falcon Heavy. “It has so much more capability than any other vehicle I think we can start to realistically contemplate missions like a Mars sample return.”
The Hawthorne, Calif.-based company already has a $1.6 billion contract with NASA to use Falcon 9 and the company’s Dragon capsule to launch cargo to the international space station after the space shuttles retire. The firm also hopes to outfit Dragon capsules to carry astronauts, and eventually transport both astronauts and space tourists to orbit.
SpaceX also has more than $2.5 billion in launch contracts to deliver satellites to orbit for the next few years.
The Falcon 9 has made two successful test launches so far, the last in December 2010, when it launched the Dragon for the first time. The capsule was successfully recovered from the Atlantic Ocean after orbiting the Earth.
The new Falcon Heavy is designed to stand 69.2 meters tall and weigh about 1.4 million kilograms. It would incorporate the standard Falcon 9 rocket, with two liquid-powered Falcon 9 first-stage boosters strapped on its sides.
It would initially launch from Vandenberg, but eventually could launch from Cape Canaveral Air Force Station in Florida as well.
The current Falcon 9 can loft about 10,450 kilograms to low Earth orbit from its launch site in Cape Canaveral. Falcon Heavy boosters will boost that up to nearly 53 tons, Musk said.
