First Soyuz almost ready for launch from French Guiana

May 05, 2011
Final testing of the Soyuz launch site at Europe’s Spaceport in French Guiana began on 29 April 2011 with a simulated launch campaign that will end on 5 May 2011. This dry-run ensures that the Soyuz and the new facilities work together perfectly, while allowing the teams to train under realistic launch conditions. It also validates all the procedures during the final phase before launch. The vehicle was transferred from the preparation building to the launch zone and erected into the vertical position.

The final countdown before its maiden flight later this year has begun for Soyuz with a simulated launch campaign at Europe’s Spaceport in French Guiana.

This dry run ensures that the and the new facilities work together perfectly, while allowing the teams to train under realistic conditions. It also validates all the procedures during the final phase before launch, except the fuelling of the vehicle.  

Last Friday, one of the two Soyuz launchers already at the Spaceport was rolled out of the preparation building horizontally using the 600 m-long railway leading to the launch platform.

The vehicle was then erected into the vertical position and suspended over the pad with the use of four support arms.

The mobile gantry, built specifically for Soyuz operations in French Guiana, was rolled out to the pad and the vehicle’s upper composite, comprising the Fregat upper stage and payload fairing, was hoisted on top of the launcher.

The rehearsal is simulating the five-day final phase before launch, planned on 4 May. The final countdown will be performed, including the gantry’s rollback to its parked position, 80 m from the pad. It will be intentionally stopped to validate the procedures in the event of a launch interruption.

The will resume on 5 May with a simulated liftoff and downrange.
  
These tests will give the green light for the first Soyuz flight from French Guiana in the third quarter of 2011.

Since each launch costs a sixth of a shuttle launch, I have the following suggestion to save the Hubble telescope at discount rate: Launch two of these rockets, one with a Soyuz crew, one with a module carrying extra fuel, spare parts, manipulator limbs and an air lock. Dock the two, rendezvous with, and grab Hubble. Then replace gyros and other worn-out parts. Use off-the shelf components for the whole thing.
