Watch Ariane 5 launch with Star One D1 and JCSAT 15

A European Ariane 5 rocket is scheduled for blastoff  Tuesday from a jungle launch pad in South America with two geostationary telecom payloads — one owned by a Saudi Arabian operator and built in Colorado by Lockheed Martin, and another for India’s space agency.

A Falcon 9 booster that flew into space last year is set to launch again Thursday from Florida’s Space Coast with an SES communications satellite on a historic mission that could make major strides in validating SpaceX’s audacious goal of recovering and reusing launchers, an achievement the company says will revolutionize the rocket business. Liftoff is set for 6:27 p.m. EDT (2227 GMT).

SpaceX kicked off its 2019 launch campaign with a mission Friday from Vandenberg Air Force Base in California carrying 10 more upgraded communications satellites into orbit to complete a refresh of Iridium’s voice and data relay network. Liftoff of the Falcon 9 rocket occurred at 7:31 a.m. PST (10:31 a.m. EST; 1531 GMT).
