Liftoff of Vega VV06 carrying LISA Pathfinder on 3 December 2015 from Europe's Spaceport, French Guiana. The satellite was placed in a low-earth transfer orbit. From there, LISA Pathfinder will use it's own propulsion module in a series of low-earth orbital maneuvers ("slingshot maneuvers") to reach the velocity necessary to reach operational orbit around Lagrange point L1.
