Aimed at safely transferring astronauts to and from the International Space Station (ISS), the Moon, Mars, and other destinations beyond low-Earth orbit (LEO), the Orion Crew Exploration Vehicle (CEV) is a state-of-the-art human spaceflight system. Lockheed Martin Corporation has selected the LDRA tool suite for software verification and automated testing on the Orion CEV program, and to enable developers to achieve the stringent safety-critical standards required to ensure safe transfer of the astronauts. NASA has awarded Lockheed Martin a multimillion-dollar contract for Orion’s development.

Made up of a number of integrated products that assist users with achieving full lifecycle support, LDRA’s tool suite will assist Orion developers in software standards checking, analysis of code coverage, unit testing, and object code verification. LDRA Testbed, the process management tool at the core of the LDRA tool suite, performs the code, quality, and design reviews on the source code. With TBrun, LDRA’s automated unit testing tool, a GUI interface automates the production of test data vectors, with test harness and stub generation completing automatically.

The LDRA tool suite capabilities are unique in their integration of requirements traceability with static and dynamic analyses, and their ability to test software on virtually any host or target system. The tool suite implements safety-critical standards such as DO-178B. Orion CEV will replace the space shuttle, scheduled to retire in 2010, and its first manned mission is targeted for 2014.
