The flight was a single-payload mission that deployed the LISA Pathfinder scientific satellite into orbit. It had a total payload mass of about 1,986 kilograms (4,378 lb), including the satellite and its adapter, which is the Vega launcher's record (as of March 2019[update]).
The LISA Pathfinder spacecraft, a technology validation for the LISA mission, had a lift-off mass of approximately 1,906 kilograms (4,202 lb), and a design lifetime of 1 year. It was developed by Airbus Defence and Space for the European Space Agency's science directorate.
The mission was planned to last 1 hour, 45 minutes and 33 seconds from lift-off until separation, placing its payload into a low Earth parking orbit with a perigee of about 207 kilometres (129 mi), an apogee of about 1,540 kilometres (960 mi), and an inclination of about 5.96°, from which the spacecraft autonomously reached its L1 Lissajous orbit.
