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.
