Live coverage: Two satellites lift off aboard Ariane 5

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.

A United Launch Alliance Delta 4-Heavy rocket climbed into space Sunday with NASA’s Parker Solar Probe on a daring mission to explore the atmosphere of the sun. Liftoff from Cape Canaveral occurred at 3:31 a.m. EDT (0731 GMT).

An Ariane 5 rocket lifted off at 2143 GMT (5:43 p.m. EDT) Thursday from French Guiana with a pair of commercial TV broadcasting satellites for AT&T and Eutelsat.
