The world is about to get its first look at SpaceX's new astronaut taxi.

Next Thursday (May 29), the company will unveil the crewed version of its Dragon spacecraft, which SpaceX hopes will be ferrying astronauts to and from the International Space Station a few short years from now.

"Sounds like this might be a good time to unveil the new Dragon Mk 2 spaceship that ‪@SpaceX has been working on [with] ‪@NASA. No trampoline needed," SpaceX's billionaire founder and CEO Elon Musk wrote in a Twitter post late last month. "Cover drops on May 29. Actual flight design hardware of crew Dragon, not a mockup."

The manned vehicle is an upgraded variant of SpaceX's robotic Dragon cargo capsule, which has already flown three resupply missions to the space station for NASA. The company holds a $1.6 billion deal to make 12 such flights for the agency.

SpaceX has been developing the manned Dragon with financial help from NASA's Commercial Crew Program, which aims to get at least one private American astronaut taxi up and running by 2017. The program seeks to end the nation's reliance on Russian Soyuz spacecraft, which have been astronauts' only means of transport to and from the orbiting lab since NASA's space shuttle retired in 2011.

NASA's commercial crew program has also supported the efforts of other companies. For example, Boeing and Sierra Nevada Corp. also received funding recently to advance work on their vehicles — the CST-100 capsule and a space plane called Dream Chaser, respectively.

The spaceflight company SpaceX is one of several firms building private space taxis and cargo ships to launch astronauts and supplies into space. But there's more to SpaceX than meets the eye. Test your SpaceX know-how here.

While Musk hopes SpaceX wins a contract to carry astronauts to and from the space station for NASA, he has bigger dreams for the company. Musk has said he established SpaceX primarily to help humanity become a multiplanet species — specifically, to play a major role in establishing a permanent Mars colony.

The company is therefore working hard to develop fully and rapidly reusable rockets, which Musk says could reduce the cost of spaceflight by a factor of 100. During last month's Dragon launch toward the space station, for example, SpaceX succeeded in bringing the first stage of its Falcon 9 rocket back to Earth for a soft ocean splashdown.
