What looks like NASA's Orion capsule, costs about the same as an Orion capsule but isn't made of metal? Why that would be NASA's Composite Crew Module, a structural prototype commissioned by NASA to determine if there would be any advantages to using new polymers to fabricate its planned replacement for the retiring space shuttles.
The NASA Engineering and Safety Center, set up in the wake of the Columbia accident to provide independent testing, analysis and assessments of the agency's high-risk programs, has been studying the alternative Orion capsule for about three years.
The NESC found that an alternative Orion was feasible but a detailed design would be needed to ascertain if it could meet mass requirements and manufacturing concerns. NASA told it to go ahead and build one.
Here's a quick synopsis of the project from NSEC's website:
The team ... focused on a design that utilizes aluminum honeycomb sandwich and solid polymer matrix laminate material systems.
The design integrates the capsule backbone with the floor and pressure shell walls, which helps share the structural loads - particularly important for water landings. The design also trims the capsule by about 150 pounds. The capsule is constructed in two major sections: an upper and a lower pressure shell.
