Sometimes all it takes is fresh air to get a new lease of life. ESA's Proba-2 microsatellite is a good example: an influx of nitrogen has replenished its fuel tank, in the process demonstrating a whole new space technology.
On 16 August a telecommand was sent from ESA's Redu ground station in Belgium to boost the gases in Proba-2's unusual 'resistojet' engine.
Used to maintain the microsatellite's orbit at 600 km altitude, this experimental engine runs on xenon gas heated before ejection to provide added thrust.
The command added nitrogen gas to the fuel tank, bringing its pressure
