Express-AT1 and Express-AT2 dual launch success
A Proton-M/Breeze-M rocket carrying Express-AT1 and Express-AT2 telecommunications satellites lifted off from the launch pad at the Baikonur cosmodrome on at 03:08 Moscow Time.
The Express-AT1 spacecraft separated from the vehicle at 12:10 and 18 minutes later the nominal separation of Express-AT2 from the upper stage took place. The satellites are healthy in orbit with all their mechanical subsystems deployed. It is the third dual launch in ISS-Reshetnev’s history.
Prior to commissioning, Express-AT1 and Express-AT2 spacecraft are scheduled to undergo a series of flight tests, and then they will be moved to their assigned orbital locations of 56° East and 140° East respectively.
The Express-AT1 telecommunications satellite, built around the Express-1000HTB platform, weighs 1800 kg and provides 5600 W of power to the payload. It is equipped with 40 Ku-band transponders (32 active and 8 spare transponders).
The Express-AT2 telecommunications satellite, built around the Express-1000K platform, weighs 1250 kg and provides 2850 W of power to the payload. It is equipped with 16 Ku-band transponders.
Both spacecraft have projected lifespans of 15 years.
