A flying laboratory, ESA's OPS-SAT will be the first of its kind, with the sole purpose of testing and validating new techniques in mission control and on-board satellite systems. OPS-SAT is devoted to demonstrating drastically improved mission control capabilities, that will arise when satellites can fly more powerful on-board computers. The satellite is only 30cm across, but it contains an experimental flight computer ten times more powerful than any current ESA spacecraft.
