NASA says test flight of new heat shield a success

NASA says an experimental heat shield for future spacecraft landings has successfully survived a test launch that brought it through the earth's atmosphere at speeds of up to 7,600 mph (12,230 kph).

The demonstration launch occurred Monday at the Wallops Flight Facility in Virginia.

A high-speed Navy Stiletto boat is attempting to retrieve the 680-pound (310-kilogram) heat shield.

The purpose of the launch was to determine whether a space capsule can use an inflatable outer shell to slow and protect itself as it enters an atmosphere at hypersonic speed during a planetary entry and descent.
