Getting more out of our satellites

Of the approximately 5000 satellites launched since the dawn of the space age, only 1000 are operating now. That’s because when satellites break or run out of fuel, they’re simply thrown away.
As deputy program manager of NASA’s Satellite Servicing Capabilities Office, Benjamin Reed leads a team working to create an era of re-use, assembly, and servicing to get more out of our satellites, and at ESC Boston on Thursday he laid out the plan to make that happen.
The cost of launching something into space is a major factor in the way satellites are designed. The median satellite costs about $250 million to build and almost half that to launch, so each one is carefully designed to be very reliable and takes years to build. That also comes at a cost.
“Every satellite is technologically obsolete the day it launches,” said Reed. “The paradigm of getting into space drives how we build satellites.”

Quick Reaction Saves ESA Space Telescope

Once launched, most spacecraft are out of reach of any upgrades or repairs. Mission critical problems must be solved with whatever’s still working on board, and sometimes there’s very little time. Recently ESA’s INTEGRAL team was confronted with a ruthlessly ticking three hour deadline to save the mission.
