Sierra Nevada Corporation (SNC) welcomes the United Launch Alliance’s (ULA) new Human Launch Services organization, which will support the company’s efforts to human rate the Atlas V launch vehicle. This office will now serve as an interface between SNC’s Dream Chaser(R) orbital crew vehicle team and ULA’s Atlas V launch vehicle team.

“The SNC team is looking forward to working with ULA’s Human Launch Services organization and continuing to build upon the success of our seven year partnership,” said Mark Sirangelo, Corporate Vice President of Sierra Nevada Corporation’s (SNC) Space Systems. “Our long-standing relationship has allowed us to greatly evolve our integrated crew transportation system and gives the DCSS the advantages, such as flight-proven reliability, that only a mature launch system can provide.”

Integration efforts between the Atlas V launch vehicle and the Dream Chaser(R) orbital crew vehicle began in 2005 at the inception of the DCSS Program. The DCSS is now participating in the second round of NASA’s Commercial Crew Development Program. The system is currently being integrated by a joint ULA/SNC team as the DCSS progresses toward demonstration and operational flights in the next few years.
