Sierra Nevada to Fly Dream Chaser on Stratolaunch

Confirming a report tweeted earlier today by Jeff Foust at Space News, Sierra Nevada Corporation issued a press release this afternoon announcing that a scale version of Dream Chaser will be developed to fly on the Stratolaunch.

As designed, the Dream Chaser-Stratolauncher human spaceflight system can carry a crew of three astronauts to LEO destinations. This versatile system can also be tailored for un-crewed space missions, including science missions, light cargo transportation or suborbital point-to-point transportation. The scaled crewed spacecraft design is based on SNC’s full-scale Dream Chaser vehicle which, for the past four years, has undergone development and flight tests as part of NASA’s Commercial Crew Program.

Chuck Beames, president, Vulcan Aerospace Corp and executive director for Stratolaunch Systems said, “Combining a scaled version of SNC’s Dream Chaser with the Stratolaunch air launch system could provide a highly responsive capability with the potential to reach a variety of LEO destinations and return astronauts or payloads to a U.S. runway within 24 hours.”

“This relationship would expand our portfolio to include the highly flexible Stratolaunch system for launching reusable crewed or uncrewed spacecraft, or for rapid satellite constellation deployment,” said Mark Sirangelo, corporate vice president of SNC’s Space Systems.

In addition to supporting development of human spaceflight capability, SNC studied satellite launch options and mechanisms, as well as point-to-point transportation options using the Stratolaunch launch system with a Dream Chaser spacecraft derivative. The Stratolaunch system is uniquely designed to allow for maximum operational flexibility and payload delivery from several possible operational sites, while minimizing mission constraints such as range availability and weather.

This post will be updated tomorrow once more information is available.

UPDATE October 1, 2014 9:40 AM EDTAlan Boyle at NBC News releases the first artist's concept of the Dream Chaser/Stratolaunch combo.
