With its perpetually upturned pectoral fins and blunt nose, the Dream Chaser looks more like a killer whale than a spacecraft. But unlike an orca, the Dream Chaser will soon be going to orbit: it’s set to take food and supplies to the International Space Station (ISS) later this year when it travels to space for the first time.
The Dream Chaser’s trip to space will make it the latest commercial vehicle to visit the ISS as part of NASA’s “commercial resupply services” program. But leaders at Sierra Space, the company that built this finned craft, have visions that go beyond such deliveries: they hope that someday Dream Chaser will carry people to space and that it can act as a kind of ready-made space program for countries that don’t want to or don’t have the resources to reinvent these particular wheels. Beyond that, Sierra Space officials think Dream Chaser could deliver supplies or people to various places on Earth for the Department of Defense by going from point to point around the world at a faster clip than a typical plane.
But before any of that happens, Dream Chaser must make its maiden voyage, set for sometime later this year.
NASA’s Space Shuttle was the original grocery deliverer and taxi service for the space station. As the shuttle retired in 2011, “we had to go start taking a look at a couple of avenues to support the space station,” says Phil Dempsey, ISS Transportation Integration Office manager. NASA turned to private corporations.
If companies could build space deliverers, NASA could simply buy their services instead of having to build and maintain its own vehicles. NASA’s first phase of contracts went to SpaceX and Orbital ATK (now Northrop Grumman). In the second phase, Sierra Space became the third company to win a contract. Sometime this year, the Dream Chaser will be loaded onto a United Launch Alliance Vulcan Centaur rocket at Cape Canaveral, Fla., whose runway it will land on upon return.
