A distributed data system that NASA uses to archive data collected by Solar System robotic missions and ground-based support data associated with those missions. PDS is managed by NASA Headquarters' Planetary Sciences Division. The PDS is an active archive that makes available well documented, peer reviewed data to the research community. The archive and data within are held to high quality standards established by the PDS. The PDS is divided into a number of science discipline "nodes" which are individually curated by planetary scientists.
Industry:Aerospace
The Mars Environmental Survey (MESUR) engineering prototype later named Mars Pathfinder.
Industry:Aerospace
Circles in parallel planes to that of the equator defining north-south measurements, also called lines of latitude.
Industry:Aerospace
A modular upper stage operated with solid propellant, used with the Space Shuttle, Delta, and Titan launchers. The rocket was used to carry satellites from a low earth orbit to a geostationary transfer orbit or an interplanetary course. The payload was spin stabilized by being mounted on a rotating plate.
Industry:Aerospace
A quantity of data used as the basis for multiplexing, for example in accordance with CCSDS.
Industry:Aerospace
A multiplier, x1015, from the Greek "pente" (five, the "n" is dropped). The reference to five is because this is the fifth multiplier in the series k, M, G, T, P. See the entry for CGPM.
Industry:Aerospace
Elapsed time between Earth and spacecraft or solar system body.
Industry:Aerospace
Configuration in which one celestial body is opposite another in the sky. A planet is in opposition when it is 180 degrees away from the sun as viewed from another planet (such as Earth). For example, Saturn is at opposition when it is directly overhead at midnight on Earth.
Industry:Aerospace
A large number of comets theorized to orbit the sun in the neighborhood of 50,000 AU.
