People say we're running out of energy. That's only true if we stick with these old 19th century technologies. We are awash in energy from sunlight.

Disposable rockets are preventing us from making Star Trek a reality

RATE THIS! +8

While I’ve always believed  our lack of warp drive technology is what’s kept humanity from meeting the Vulcans, SpaceX founder and CEO Elon Musk said there’s another, more practical roadblock: Rockets, specifically the kind that you only get a single use out of.


OK, he didn’t actually mention Vulcans, but he was very clear that the future of space travel depends on us being able to create a rocket that isn’t a zillion dollars and can be reused multiple times.


“Reusable rockets are vastly important if you think its important that humanity span beyond earth and become a multi-planetary species,” Musk said to two very crowded large ballrooms during a keynote at SXSW yesterday. “If you can imagine watching Star Trek, and if they built a new star ship after every trip? It’s pretty silly. And all the other transports we use — planes, trains, cars, bikes — are all reusable. But not rockets.”


Musk’s initial space project that would have sent a platform-like green house to Mars, that would have (hopefully) eventually pave the way for humans to survive on the planet. He and his team initially nailed all the costs, the scientific process of making it actually work, how to send pictures of it back to earth — pretty much everything except for those asshole disposable rockets.


“The first idea I came up with was actually to do philanthropic mission to send a greenhouse to the surface of mars, with seeds of dehydrated gel that would hydrate upon landing,” Musk said. “You’d have this cool greenhouse, with green plants on a red background. That would be the money shot.”


Musk explained that the cost of disposable rockets makes space travel truly prohibitive for a large number of businesses to jump into the field. For instance, he said the cost of the fuel and oxygen on SpaceX’s Falcon 9 space craft is .9 percent of the entire cost of the trip, while the rocket accounts for the rest of it.
