Chris Forrester, on 29-06-2008Arianespace is readying two satellites for launch – and both are vital craft for their Arab and Indian backers. Arabsat’s BADR-6 satellite and ProtoStar-1 are already in place this past weekend. July 4 is the scheduled launch date.

ProtoStar-1 is urgently needed by Zee TV’s Dish DTH arm to launch additional channels into India, while BADR-6 is just the latest of a new fleet being assembled by Arabsat to handle explosive growth out of the Middle East.

Final satellite integration began with the encapsulation of ProtoStar I in the Ariane 5's payload fairing. ProtoStar I is the upper passenger in the mission's dual payload "stack," and is positioned atop the SYLDA 5 payload dispenser system.

“With the upper payload ‘stack’ component now complete, all is ready for its installation on Ariane 5, where it will be positioned over the BADR-6 spacecraft. BADR-6 was integrated June 26 atop the heavy-lift launcher's core cryogenic stage,” said Arianespace.

During the July 4 launch, Ariane 5's payload fairing will be jettisoned at 3 min., 15 sec. into the mission as the vehicle completes its initial ascent through the denser layers of the Earth's atmosphere. ProtoStar I is to be released at some 27 min. into the mission, followed by the separation of SYLDA 5 - which exposes BADR-6 for its deployment at 35 min., 39 sec. into the flight.
