Spacecraft Parameter Database Tool

Goddard Space Flight Center, Greenbelt, Maryland The GOES-R Program has requirements to maintain knowledge of the GOES-R satellite onboard memory contents, including managing general satellite operations tables; processor memory dumps for memory verification; creating command loads, memory (table) loads, and command sequences to operate the satellite; verifying stored command and memory (table) loads; and to provide for operator-initiated memory dumps from satellite processors. The principal limitation is the tie to specific spacecraft architecture.

Moon Tours Android

NASA’s Jet Propulsion Laboratory, Pasadena, California This Android app provides a native interface to the Lunar Mapping and Modeling Portal’s (LMMP) lunar data archive and analysis tools. It complements the iOS app previously released, incorporating a very similar feature set. Both apps contain a subset of the functionality available in the desktop/Web version. Compared to the iOS version of the LMMP, the Android version provides the additional tools necessary to perform elevation analysis and perimeter/area measurements.
