Workers at NASA Ames Research Center are developing durable, oxidation-resistant, foam thermal protection systems (TPSs) that would be suitable for covering large exterior spacecraft surfaces. The TPSs would have low to moderate densities, and temperature capabilities comparable to those of carbon-based TPSs, which are reusable at 3,000 degrees F. These foams might be useful as catalyst supports and filters on Earth and in outer space. Click here for more info.

A system that estimates the global radius of curvature (GRoC) of a segmented telescope mirror has been developed by the Marshall Space Flight Center for use in a larger system that exerts precise control over the displacements of the mirror segments. This system makes it possible to control the GRoC of the mirror with sufficient precision to obtain the best possible image quality, and to impose a required wavefront correction on incoming or outgoing light.
