Juicing up our satellite: MetOp-B fuelled

From Luca (ESA), Baikonur, 31 August MetOp-B’s Reaction Control System (RCS) – the mission's thrusters – has been fuelled and pressurised in preparation for launch on 17 September. The satellite was transferred to Starsem's Hazardous Processing Facility for the operation and a specialist team from Astrium carefully checked their equipment before operations could begin. The tank of thruster fuel (MetOp uses hydrazine propellant for propulsion. ) was also transferred from the storage area to the facility. Hydrazine is a hazardous chemical and has to be handled carefully to ensure the safety of both personnel and the spacecraft. Hydrazine is highly flammable and also poses health risks if it comes in contact with skin or...

MetOp checked for fuelling

From Nick (ESA), Baikonur, 24 April Final health checks on MetOp-B’s Reaction Control System (RCS) have been completed in preparation for fuelling. The RCS consists of tanks that will contain the Hydrazine fuel pressurised with Helium gas, and several small thrusters that can be used to adjust the satellite’s orbit after separation from the launcher. The specialist team from Astrium Ltd, who prepare the RCS for launch, arrived in Baikonur in mid-April and quickly began to test the RCS to make sure everything was working correctly following shipment.  Tests include functional checks of the valves and pressure transducers, a calibration of the pressure sensors and tests to ensure there are no leaks...
