NASA Space Science Data Coordinated Archive

Welcome to the NASA Space Science Data Coordinated Archive, NASA's archive for space science mission data.

NSSDCA is anticipating the return to service of the NSSDCA Master Catalog and the Terrestrial Planet Mileage Guide within the next week or so. The SPASE Data Registry will hopefully return to service roughly a week or so thereafter. We apologize for the lengthy downtime and appreciate your understanding. (Updated: 2018-11-15, EVB II)
