Europe’s LISA Pathfinder spacecraft, carrying high-tech thrusters and ultra-sensitive motion sensors to be used in a future gravitational wave detection mission, blasted off from French Guiana early Thursday aboard a nearly 100-foot-tall (30-meter) Vega rocket.
After lifting off at 0404 GMT Thursday (1:04 a.m. French Guiana time; 11:04 p.m. EDT Wednesday), the four-stage Vega booster turned east and accelerated into orbit with LISA Pathfinder, deploying the satellite an hour and 45 minutes later.

During a fourth spacewalk Saturday to wrap up repairs of the coolant system in a $2 billion cosmic ray detector, Italian astronaut Luca Parmitano and Drew Morgan discovered a leak in one of eight coolant lines that were spliced into a new pump module during three earlier excursions. But Parmitano was able to tighten a fitting on the line and the astronauts were able to complete the repair work, setting the stage for the instrument to resume science operations.
Arianespace plans 11 launches from French Guiana this year, including eight flights by the heavy-lift Ariane 5 rocket with up to a dozen large telecommunications satellites and four spacecraft for Europe’s Galileo navigation system.
Mounted on a mobile platform, a European Ariane 5 rocket followed dual rail tracks across the Guiana Space Center in South America on the way to its jungle launch complex Monday, a day before its scheduled blastoff with four satellites to expand Europe’s independent navigation network.
