Probe into off-target Ariane 5 launch begins, SES and Yahsat payloads healthy
Arianespace will convene an independent inquiry board chaired by a top European Space Agency official to investigate why an Ariane 5 rocket flew off course Thursday night after liftoff from French Guiana with the SES 14 and Al Yah 3 telecom satellites, but both payloads will be salvaged to accomplish their planned missions, officials said Friday.

Live coverage: Ariane 5 lifts off from French Guiana
A European Ariane 5 rocket delivered two commercial communications satellites to orbit Thursday after Arianespace’s ground team lost telemetry from the launcher during its climb into orbit, raising concerns that the mission might have failed. The SES 14 and Al Yah 3 satellites are confirmed in orbit and healthy, but the parameters of their orbits are unknown. Both were heading toward 22,000-mile-high geostationary perches over the equator.
