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."

In this twenty-second edition of ESA's "Earth From Space," two images from from the Envisat satellite are examined, showing northern France and its urban heat islands.

Earth from Space is presented by Kelsea Brennan-Wessels from the ESA Web-TV virtual studios. In the twentieth edition we look at an image of the Juruá River snaking through the Amazon rainforest in western Brazil.
