Arianespace is returning an Ariane 5 rocket — loaded with three U.S.-built satellites — back to its final assembly building in French Guiana to replace a suspect sensor on the vehicle that prompted officials to cancel a launch attempt Friday. Arianespace said Monday that the swap will delay the launch until around Aug. 14.
Arianespace’s third Ariane 5 launch of the year was set liftoff Friday from Kourou, French Guiana, but an issue with a sensor on the rocket’s first stage liquid hydrogen tank caused officials to scrub the launch attempt. The Ariane 5 is poised to carry three U.S.-built commercial satellites into orbit, while testing a few rocket upgrades, including a modified fairing needed for the launch of the James Webb Space Telescope next year.
The next flight of Europe’s heavy-lift Ariane 5 rocket, set for July 28 from French Guiana, will carry a record payload of three multi-ton satellites toward geostationary orbit, including a pair of U.S.-built commercial communications payloads and Northrop Grumman’s second robotic satellite servicing spacecraft.
Northrop Grumman’s first Mission Extension Vehicle captured spectacular views of the commercial Intelsat 901 communications satellite as it approached for docking this week, providing the first-ever up-close public views of a spacecraft flying near geosynchronous orbit more than 22,000 miles above Earth.
A Northrop Grumman robotic servicing spacecraft has hooked up with an aging Intelsat communications satellite more than 22,000 miles over the Pacific Ocean, accomplishing the first link-up between two commercial satellites in space, and the first docking with a satellite that was never designed to receive a visitor.
A Proton booster rocketed away from the Baikonur Cosmodrome in Kazaskhtan Wednesday with a Eutelsat television broadcasting craft and the satellite industry’s first commercial in-space servicing vehicle. The successful launch marked the first commercial Proton mission under the auspices of International Launch Services in more than two years.
A Russian Proton rocket lifted off at 1017 GMT (6:17 a.m. EDT) Wednesday from the Baikonur Cosmodorme in Kazakhstan. After a marathon 16-hour-long launch sequence, the Proton and its Breeze M upper stage will deploy the Eutelsat 5 West B video broadcast satellite and a robotic satellite servicing payload aiming to attempt the first-ever docking in geosynchronous orbit.
