With the Preliminary Design Review (PDR) of its software on May 18, the company now has completed more than 40 milestones under partnerships supporting NASA’s Commercial Crew Program (CCP).
“When it comes to designing a spacecraft safe enough to transport humans, software is as important as the hardware,” said Ed Mango, CCP manager. “Boeing has made an excellent effort to take safety into consideration while developing critical software components of its spacecraft.”
Boeing’s CST-100 is designed to be a reusable, capsule-shaped spacecraft, capable of transporting up to seven people or a combination of people and cargo. It is compatible with a variety of expendable launch vehicles. Boeing has selected United Launch Alliance’s Atlas V rocket for initial CST-100 test flights.
Software is essential to all operational aspects of the spacecraft, including launch, orbital maneuvering, docking with and separating from the space station, re-entry and landing. The testing is part of a NASA-funded Space Act Agreement under the second round of the agency’s commercial crew development (CCDev2) activities, which could eventually lead toward human spaceflight certification of the CST-100.
The Boeing team is on schedule to complete its remaining CCDev2 milestones in the next few months, including an orbital maneuvering/attitude control engine hot fire test that will provide additional data on significant elements of the spacecraft design.
All of NASA’s industry partners, including Boeing, continue to meet their established milestones in developing commercial crew transportation capabilities.
