Sierra Nevada Corporation’s Dream Chaser spacecraft recently glided to a successful landing at NASA’s Armstrong Flight Research Center located on Edwards Air Force Base in California. Completion of Dream Chaser’s free flight test on Nov. 11, 2017, was a major milestone under a space act agreement with NASA’s Commercial Crew Program.
NASA selected Sierra Nevada Corporation, along with Orbital ATK and SpaceX, for the agency’s second commercial resupply contracts to deliver critical science, research and technology demonstrations to the International Space Station from 2019 to 2024.
For the free flight test, a Columbia Helicopters model 234-UT heavy-lift helicopter carried aloft an uncrewed Dream Chaser test article, suspended at the end of a cable. The lifting-body, winged spacecraft had all the same outer mold line specifications as a flight-ready vehicle. A lifting body is a fixed-wing aircraft or spacecraft shaped so that the vehicle body itself produces lift.
After release, Dream Chaser glided on its own and landed in a manner similar to NASA’s space shuttles.
“It is very exciting that Sierra Nevada Corporation successfully completed this important free-flight test,” said Steve Stich, deputy manager NASA Commercial Crew Program. “The Dream Chaser team has done an amazing job preparing for and executing this test and the Commercial Crew Program has been with them along the way. The Flight computers and avionics systems are the same as the orbital vehicle so this test will pave the way for future landings for the International Space Station missions.”

The Atlas V rocket that will launch Boeing’s CST-100 Starliner spacecraft for the company’s uncrewed Orbital Flight Test for NASA’s Commercial Crew Program is coming together inside a United Launch Alliance facility in Decatur, Alabama.
The uncrewed Orbital Flight Test is intended to prove the design of the integrated space system prior to the Crew Flight Test. These events are part of NASA’s required certification process as the company works to regularly fly astronauts to and from the International Space Station. Boeing and United Launch Alliance have begun conducting integrated reviews of components, software and systems along with decades of Atlas data to ensure integrated vehicle test simulations are similar to real-life conditions during missions. Starliners for the uncrewed and crew test flights, including for the pad abort test, are in various stages of production and testing.
NASA’s Commercial Crew Program is working with private companies, Boeing and SpaceX, as they each develop unique systems to fly astronauts for the agency to and from the space station. SpaceX is developing the Crew Dragon, or Dragon 2, spacecraft to launch on a Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. Boeing’s Starliner will liftoff on the United Launch Alliance Atlas V rocket from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida.
