Spacecraft Resembles Apollo Configuration With Crew And Service Modules

Boeing has pulled the trigger on its proposal for the second round of NASA's Commercial Crew Development (CCDev) program. The company plans to advance the design of its Crew Space Transportation (CST)-100 spacecraft and Commercial Crew Transportation System and continue to demonstrate key technologies.

"In the same way that Boeing helped launch commercial aviation more than 80 years ago, we are working to develop what could become a true commercial space transportation system: a commercial service to take people to the International Space Station and other Low Earth Orbit destinations," said Brewster Shaw, Boeing Space Exploration vice president and general manager. "We plan to further mature our design and continue the development process toward our first crewed flight in 2015."

The proposal is for an approach that will significantly mature the CST-100 design through demonstrations of critical subsystems. The CST-100 spacecraft is designed to support NASA's primary objective of affordable access to Low Earth Orbit. It will carry up to seven crew and passengers, is reusable up to 10 times, and is compatible with a variety of expendable launch vehicles. The spacecraft -- which is comprised of a Crew Module and a Service Module -- draws on Apollo-proven aerodynamic characteristics in a design that uses commercial, off-the-shelf, cost-effective technologies.

In October, Boeing completed a Systems Definition Review with NASA that defined the CST-100 spacecraft's system characteristics and configuration and established a baseline design. Other major accomplishments of the first round include:

• Design, build and test of a pressurized structure of the crew module
• Creation of a mock-up of the spacecraft to ensure the crew can enter and exit the vehicle safely, reach control switches and easily see through windows
• Demonstration of manufacturability of the base heat shield structure and thermal protection system to protect the crew during re-entry into Earth's atmosphere
• Development of an avionics systems integration facility to support rapid prototyping and full-scale development
• Development of a rendezvous sensor and associated guidance and navigation software that allows the vehicle to autonomously approach and dock with the International Space Station and the planned Bigelow Orbital Space Complex
• Demonstration of airbag land landing, water landing, post-water landing uprighting and life-support systems.

"We look forward to continuing our joint efforts with NASA to ensure CCDev's success," said Shaw. "Enabling commercial-crew access to Low Earth Orbit allows NASA to focus on deep space exploration and thereby ensure a continued leadership role for the U.S. in human spaceflight for generations to come."
