Amateurs contributed some of the data in a major aggregation of satellite specifics posted online last month by the Union of Concerned Scientists, according to Laura Grego, a staff scientist for the Cambridge, Mass., organization. As part of its push for public awareness of space-based government activities, the UCS (ucsusa.org/satellite_database) lists some 800 active satellites by launch date, country of origin, sponsor, and orbital coordinates. It ignores inactive satellites and other space junk.
