NASA’s Orion Crew Exploration Vehicle Built with INTEGRITY-178B

SANTA BARBARA, CA—September 8, 2008
Green Hills Software, Inc., the technology leader in device software optimization (DSO) and real-time operating systems (RTOS), today announced that NASA is using Green Hills Software's Platform for Avionics, including the safety-certified INTEGRITY®-178B real-time operating system, in safety critical electronics – including the command computer - aboard NASA’s Orion crew exploration vehicle.

"The Lockheed Martin Orion team is working to build the state-of-the-art crew exploration vehicle which focuses first and foremost on crew safety and spacecraft reliability," commented Gary Shubert, Orion Flight Software manager for Lockheed Martin. "Lockheed Martin selected Green Hills Software’s INTEGRITY® and INTEGRITY-178B operating systems for use in the spacecraft’s avionics systems, including the Flight Control Module (FCM), Spacecraft C3I Communication Adapter (SCCA), and Backup Emergency Controller. Green Hills Software was determined to be the most technically mature and offered a more economical commercial off-the-shelf solution."

"Green Hills Software’s Platform for Avionics is the industry choice for the most demanding safety and security critical electronics applications – where human life must be protected," commented David Kleidermacher, chief technology officer, Green Hills Software. "We are pleased that NASA and its contractors have put their trust in Green Hills Software to help realize the vision of next-generation human space exploration."

About the Orion Crew Exploration Vehicle
The Orion crew exploration vehicle will transport a new generation of explorers to the moon, with crewed flights scheduled to begin in 2015. Orion is part of NASA’s Constellation Program, the largest space initiative in 30 years, to send human explorers back to the moon and then onward to Mars and other destinations in the solar system. The new Orion and Ares space transportation system will carry crew and cargo to the International Space Station, rendezvous with landing modules for exploration of the moon and Mars, and serve as the return vehicle back to Earth. Orion will take advantage of the latest 21st century technology in electronics, propulsion, life support, and heat protection systems.

About the Green Hills Platform for Avionics
The Platform for Avionics includes the INTEGRITY and INTEGRITY-178B RTOSs, a complete toolset for safety critical software development, support for the aviation industry standard ARINC-653 application software interfaces, and the documentation and services required for U.S. FAA DO-178B Level A safety certification. The INTEGRITY RTOS’ partitioning features allow developers to deploy multiple applications on a single processor, at multiple safety certification levels. This powerful capability enables developers to reduce the number of on-board computers needed to support multiple software systems. Furthermore, the Platform for Avionics with INTEGRITY-178B is the only safety critical RTOS certified for multiple languages, including Ada, C, and Embedded C++, allowing developers to choose the language and kernel best suited to meet their development needs. Green Hills Software is the most widely deployed safety critical commercial real-time operating system solution, powering avionics systems such as the F-35 Joint Strike Fighter and flight controls for the Boeing 787 Dreamliner.
