Sierra Nevada Corporation Plays Critical Role in International Space Station Missions

Sparks, Nev., January 13, 2014 – Sierra Nevada Corporation (SNC) congratulates Orbital Sciences Corporation (Orbital) on the successful and historic launch and berth of its Cygnus advanced maneuvering spacecraft to the International Space Station (ISS) for Orbital’s first NASA Cargo Resupply Mission known as CRS-1.

SNC is an integral part of the Orbital Cygnus team to provide the Cygnus Passive Common Berthing Mechanisms (PCBMs) in partnership with Thales Alenia Space of Turin, Italy for integration into the Pressurized Cargo Modules (PCMs) that Thales Alenia is supplying to Orbital.

The PCBM is the berthing mechanism that, when attached to the ISS pressurized element, provides a sealed passageway for movement of cargo between the Cygnus spacecraft and the ISS. SNC successfully built and delivered the PCBMs in its Louisville, Colo., facility for all of the Cygnus missions currently under contract with NASA.  The CRS-1 mission is the first of eight missions scheduled to use SNC’s PCBMs.

“The relationship between SNC, Thales Alenia, Orbital and NASA represents the best of commercial, government and international partnerships” said Mark Sirangelo, corporate vice president and head of SNC’s Space Systems. “Orbital has again demonstrated its advanced capabilities in delivering quality, reliable and efficient space programs.  SNC is proud to be a part of this international commercial space alliance and we look forward to future successful missions of the Cygnus spacecraft.”

In addition to the contract with Thales Alenia, SNC was recently awarded a contract to supply NASA with the same complex PCBM’s which will be the interface for the berthing of the Bigelow Expanded Activity Module (BEAM) to the ISS. BEAM is scheduled to launch in 2015.
