Easy rider: Marshall Aerospace of Cambridge played a key role in the California launch earlier this month of a Nasa research satellite, part of the Orbital Sciences Corporation’s programme to put satellites into low earth orbit. Marshall modified a Tri-Star aeroplane to lift the Pegasus rocket to 40,000ft, where it blasted the satellite into orbit. Its engineers also designed a vent stack system to keep air and moisture away from the frozen hydrogen used to cool the rocket’s infrared telescope, and prevent the hydrogen from exploding.
