WASHINGTON — NASA will hold a media teleconference at 1 p.m. EDT on Tuesday, Sept. 20, to announce the company that will lead the agency’s Composite Cryotank Technologies Demonstration effort.

The selected company will design and manufacture two lightweight composite cryogenic propellant tanks. The demonstration effort will use advanced composite materials and manufacturing techniques to develop new technologies that could be applied to multiple future NASA missions, including human space exploration beyond low Earth orbit. The Composite Cryotank Technologies Demonstration effort is part of NASA’s Space Technology Program.

Participants will be:

— Michael Gazarik, director of NASA’s Space Technology Program at NASA Headquarters in Washington

— Robert Lightfoot, director of NASA’s Marshall Space Flight Center in Huntsville, Ala.

— John Vickers, project manager of NASA’s Composite Cryotank Technology Demonstration effort at Marshall

To participate, reporters should call 800-369-6087 and use the passcode “CRYO.” Audio of the call will be streamed live at: http://www.nasa.gov/newsaudio

By investing in high payoff, disruptive technology that industry does not have today, NASA matures the technology required for its future missions while proving the capabilities and lowering the cost of government and commercial space activities.
