SpaceX Is About To Land A Rocket On An Ocean Platform - A Feat That Could Forever Change Spaceflight
In a game-changing move, SpaceX is going to try and land a used rocket atop a floating platform in the ocean.
If successful, the company will set a new standard in space exploration - one that could eventually cut the cost of space travel by a factor of 100, according to SpaceX founder Elon Musk.
Building a rocket that can be used more than once is an extremely important step in ultimately sending a manned space mission to and from Mars that could use the rocket to land and, more importantly, leave Mars to return to Earth.
The launch will be the fifth cargo mission to the International Space Station for SpaceX. At 1:22 pm EST, Dec. 19, the Falcon 9 boosters will fire, launching the rocket and its 3700-pound cargo out of the Cape Canaveral Air Force Station in Florida and into the skies.
After the Falcon 9 rocket has emptied most of its fuel, it will detach from the Dragon spacecraft, which will carry the payload of food, science experiments, and other supplies to the ISS.
The Falcon 9 rocket will fall back to Earth, and this is when things will get exciting for SpaceX - the rocket will, for the first time, try to land itself upright on a giant ocean platform.
Reusable Rockets
In September 2013, SpaceX successfully fired boosters as the rocket fell to Earth, slowing it down so it could land softly. That test landed in the ocean, seemingly at least semi-upright, but the rocket was eventually spun out of control, crashing in the ocean.
SpaceX finally achieved soft landings in the ocean for two missions earlier this year, but the 14-story tall rocket was irreversibly damaged when it toppled sideways into the high seas. But SpaceX is determined. Since landing in the water won't work, they've turned to something else.

The new plan? Create a self-righting floating platform to sit in the ocean and wait for the rocket's return.
"I think we've got a chance of landing on a floating landing platform," Elon Musk said last October at the MIT AeroAstro Centennial Symposium. "And if we land on that, then I think we'll be able to re-fly that booster."
Just last month, Musk tweeted images of the football-field long platform. They plan to use GPS tracking, the rockets newly attached "X-wings," and other technology to help safely guide the multi-million-dollar Falcon 9 onto the platform.
"It's probably not more than a 50% chance or less of landing it on the platform," Musk said, still optimistic at the MIT AeroAstro Centennial Symposium. "But there's at least a dozen launches that will occur over the next 12 months, and I think it's quite likely, probably 80 to 90% likely, that one of those flights will be able to land and re-fly. So I think we're quite close."
