Vega/LISA Pathfinder launch timeline
Follow the major events during the launch of Europe's LISA Pathfinder gravitational probe testbed, from liftoff of its Vega rocket booster from French Guiana through deployment into its initial orbit.
LISA Pathfinder launch grounded to analyze Vega upper stage
Launch managers in French Guiana have delayed liftoff of a European gravitational probe pathfinder at least one day to study out-of-bounds thermal readings from the upper stage of its Vega rocket booster, officials said Tuesday.
Finely-crafted experimental space probe ready for launch
A modest European-built spacecraft tuned to test the delicate, cutting edge technologies required to detect gravitational waves, a measurement that scientists say could yield unforeseen discoveries about the universe, is awaiting liftoff aboard a solid-fueled Vega rocket this week.

The European Space Agency's LISA Pathfinder spacecraft, destined to test the concept of gravitational wave detection a million miles from Earth, is nearly ready for launch Dec. 2.
Vega booster crowned with gravitational probe pathfinder
After criss-crossing Europe for a decade, the LISA Pathfinder satellite testbed has reached its last stop before launch in early December on a mission to demonstrate the delicate technologies required to detect elusive low-frequency gravitational waves rippling through the cosmos.
VideoRewatch the Ariane 5’s spectacular sunset liftoff
Watch multi-angle video replays of Tuesday's blastoff of an Ariane 5 rocket from the jungles of South America carrying two communications satellite for Arabsat and the Indian Space Research Organization.
Arab and Indian satellites fly aboard Ariane 5
A European Ariane 5 rocket, burning a cryogenic mixture of liquid hydrogen and liquid oxygen, thundered into the sky over French Guiana at dusk Tuesday with two communications relay satellites to serve the Arab world and India.
Photos: Ariane 5 counting down to liftoff
Launch crews rolled out a nearly 180-foot-tall Ariane 5 rocket to its launch pad Monday in a final major step before liftoff with the Arabsat 6B and GSAT 15 communications satellites to broadcast television, broadband and other telecom services across Africa, the Middle East, Central Asia and India.
Live coverage: Ariane 5 soars into space from Kourou
An Ariane 5 rocket launched Tuesday with the Arabsat 6B and GSAT 15 communications satellites to broadcast television across the Middle East, North Africa and Central Asia and link India with telecom and navigation services. Liftoff from Kourou, French Guiana, occurred at 2134 GMT (4:34 p.m. EST).
Launch managers sign off on final Ariane 5 flight of 2015
A launch readiness review Friday cleared an Ariane 5 rocket for liftoff Tuesday with two communications satellites for Arabsat and India, the first three missions from Europe's spaceport in French Guiana scheduled in less than 40 days.
