Will Begin With Cargo Resupply And Return Service Flight To ISS In 2021

Sierra Nevada Corporation (SNC) has selected United Launch Alliance (ULA) as the launch vehicle provider for the Dream Chaser spacecraft's six NASA missions to the International Space Station. The Dream Chaser will launch aboard ULA's Vulcan Centaur rockets for its cargo resupply and return services to the space station, starting in 2021.

"Dream Chaser can launch from any conventional rocket so we had great options," said SNC CEO Fatih Ozmen. "SNC selected ULA because of our strong collaboration on the Dream Chaser program, their proven safety record and on-time performance. This is bringing America's spaceplane and America's rocket together for best-of-breed innovation and exploration."

Under NASA's Commercial Resupply Services 2 (CRS-2) contract, the Dream Chaser will deliver more than 12,000 pounds of pressurized and unpressurized cargo to the space station and remains attached for up to 75 days as an orbiting laboratory. Once the mated mission is complete, the Dream Chaser disposes about 7,000 pounds of space station trash and returns large quantities of critical science, accessible within minutes after a gentle runway landing.

SNC's Louisville, Colorado-based Space Systems division is proudly partnering with Centennial, Colorado's ULA, boosting the already strong aerospace economic footprint in the state.

"In this very competitive launch vehicle market, we feel privileged that SNC chose to launch this block of six missions to the ISS with ULA," said Tory Bruno, ULA president and CEO. "This is one of the first contracts for our new Vulcan Centaur rocket, and the first of the six missions will serve as the rocket's second certification flight. We are excited to bring our more than 120 years of combined launch experience with our Atlas and Delta rockets, which build on a progressive history of technology development and advancement, to Vulcan Centaur."

Vulcan Centaur's flight proven design, coupled with innovative technology, is transforming the future of space launch. The new rocket will provide higher performance and greater affordability while continuing to deliver unmatched reliability and precision. Approximately 90 percent of all of Vulcan Centaur's components will be flown first on Atlas V missions, so that its first flight will have reduced risk. Vulcan Centaur is a new class of space launch vehicle with the performance of a heavy launch vehicle in just a single core.
