Check out this artist's depiction of how a retired satellite's still usable antenna might one day be salvaged and turned into a new space asset as part of DARPA's Phoenix program. The goal of Phoenix is to develop and demonstrate technologies to cooperatively harvest and re-use valuable components from retired, nonworking satellites in GEO to create new space systems at greatly reduced cost. By robotically removing and re-using GEO-based space apertures and antennas from de-commissioned satellites in the graveyard or disposal orbit, space "junk" could become space "asset."

DARPA's SeeMe program aims to give mobile, US warfighters overseas access to on-demand, space-based tactical information in remote and beyond-line-of-sight conditions. If successful, SeeMe will provide timely imagery to warfighters of their immediate surroundings via handheld devices. Articles about DARPA: http://www.scoop.it/t/science-news?tag=DARPA

What would you do if you had one week to control a research satellite? The ArduSat (Arduino Satellite) utilizes state of the art Arduino Processors to process data from over 25 sensors, all housed within a 10cm x 10cm x 10cm CubeSat miniature satellite. Participants will be able to collaborate with others to formulate, test, and ultimately deploy publicly designed applications to run experiments.

Aside from a couple particularly nasty collisions, dead satellites comprise the bulk of our planet’s space junk problem — as they die, get fried by radiation and become zombies, or are decommissioned, there’s nowhere for them to go. ViviSat aims to change that by servicing satellites where they are, pushing them into new orbits and allowing them to live longer.
