French Ariane 5 VA253 Rocket Launch Canceled Four Minutes Before Start
The launch of the European Space Agency's Ariane 5 heavy launch vehicle (ESA), planned on Saturday from the Kourou space center in French Guiana with three commercial spacecraft, was canceled four minutes before launch due to identified technical problems, operator Arianespace said.
"The pre-launch countdown was stopped due to a "red signal" received at the last moment, "the company said in a Twitter message.
According to the head of Arianespace, Stefan Israel, control sensors detected a problem in one of the booster stages.
The launch was planned to take place during the time window, which opened at 23:30 Paris time on July 31.
The launch vehicle was to put INTO orbit the MeV-2 (Mission Extension Vehicle) of the American Corporation Northrop Grumman, designed to extend the life of satellites. It was planned to dock with the Intelsat 10-02 communications satellite in geostationary orbit, which has almost exhausted its fuel reserves for maintaining orientation, and "refuel" it.
The rocket was also supposed to put the Galaxy 30 satellite of Intelsat into geostationary orbit with a perigee of 250 km and an apogee of 35.7 thousand km to expand high-frequency television coverage of the US territory. It also houses equipment from the US Federal aviation administration designed to improve the maintenance of civil aviation flights.
The third satellite that was supposed to be put into orbit is the Japanese telecommunications device BSAT-4b. Created by Maxar, it is intended for ultra-high-definition (4K and 8K) television broadcasting in Japan.
