Q&A with Guglielmo Aglietti, RemoveDebris principal investigator (members only)

The pressurized crew module and European-built service module for NASA’s first Orion spacecraft to travel to the moon will be joined together for the first time in the coming weeks at the Kennedy Space Center, with preparations — at least for Orion — on a pace to be ready for launch on an unpiloted test flight next year.

India’s most powerful communications satellite will soon be flown back to its manufacturing plant in Bangalore for additional checks, officials said this week, forcing Arianespace to scrap plans for an Ariane 5 launch in late May that was to be co-manifested with a U.S.-built television broadcast satellite for Intelsat and the government of Azerbaijan.

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.
