DARPA Developing 'Droid' Satellites
eliot1785 writes "DARPA is now developing a new breed of satellites that can be precision-maneuvered in unison and easily perform advanced operations with built-in sensors, computers and thrusters. From the article: 'David Miller, director of the Massachusetts Institute of Technology's Space Systems Laboratory, says such satellites might be used for such tasks as building giant space telescopes and closely monitoring Earth. The shuttle Discovery last week delivered the second of three satellite test "droids" that are undergoing experiments at the International Space Station.'"
Anytime DARPA or any other defense agency mentions "telescopes" they're usually referring to the kind that point down, not up. I see this as a potential test bed for a possible future interferometry-based spy satellite (be it SIGINT or IMINT).
