NASA said Nov. 2 it had modified its annual call for aeronautics research proposals to include hypersonics projects related to space flight.

“With the amendment, the Hypersonics Project of the Fundamental Aeronauts Program calls for proposals about enabling technologies and development of a new pool of expertise in two primary areas of interest. These include air-breathing access to space and entry, descent and landing of high-mass vehicles in planetary atmospheres,” NASA said in a press release.

“The solicitation is for really very fundamental, enabling kinds of technologies,” NASA spokeswoman Beth Dickey said. “Examples would be ablation sensors, high-temperature materials [and] thermal protection system materials.”

Initial submissions are due Nov. 23.
