NASA splits space station cargo deal three ways | Spaceflight Now
An unpolluted space plane developed by Sierra Nevada Corp. will join cargo carriers built by SpaceX and Orbital ATK to resupply the International Space Station beginning in 2019, NASA announced Thursday.
The Dream Chaser spaceship, originally conceived to carry astronauts, can deliver up to 12,000 pounds — 5,500 kilograms — to the space station per trip, then detach and return to Earth for a runway landing like the space shuttle.
Sierra Nevada’s lifting body spacecraft has never flown in orbit, and the company aims to drop the craft from a helicopter for an approach and landing demonstration in the coming months.
