8.2 Phase II⎯Mating to the LV and Integrated Testing on the ACS
Zenit processing
prior to spacecraft
mating
Zenit-3SL launch vehicle processing is performed on the ACS while the
spacecraft is still in the payload processing facility (see fig. 8-15). At the
pier, complete systems for loading fuels, compressed gasses, and
cryogens are provided.
The Zenit first and second stages are fully tested, the Block DM-SL is
tested and fueled, and the Block DM-SL upper stage is mated onto the
Zenit-3SL rocket. After mating and integrated testing, the launch vehicle
is now ready to receive the payload unit, which includes the encapsulated
spacecraft (see fig. 8-16).
