The facility contains infrastructure essential for the training of cosmonauts across a wide range of experiences, including simulating g-loads, mission specific/suit training, medical observation/testing and astronavigation. Key GCTC facilities include: • Full-size
mockups of all major spacecraft developed since the
Soviet era, including the
Soyuz and
Buran vehicles, the
TKS modules and orbital stations of the
Salyut Program,
Mir, and
ISS. These were co-existing or with time replaced one another inside two main training hangar halls of the center. Room 1 houses the Salyut 4, 6, Mir (Don-17KS) with Kvant (Don-37KE), Kvant 2 (Don-77KSD) and Kristall (Don-77KST) modules and a Soyuz 2 descent module simulators. Room 1A houses the Soyuz simulators (Don-7ST3 -old STK-7ST - for the Soyuz TMA; TDK-7ST4 - old TDK-7TS2 for Soyouz TM - for the Soyuz TMM; Don-732M modified for Soyuz TM and the Pilot 732 - for the TORU docking system). Other rooms house the
Salyut 7,
Spektr (Don-77KSO),
Priroda (Don-77KSI), Buran,
Zarya and
Zvezda simulators. • Zero-gravity training aircraft for simulating weightlessness (cf.
Vomit Comet), including the
MiG-15 UTI,
Tupolev Tu-104 and later the
IL-76 MDK with internal volume of . Training aircraft are based at the Russian Air Force base at
Chkalovskiy airfield. • A Medical observation clinic and testing facility. • The original office of
Yuri Gagarin and a number of monuments and busts to him and other cosmonauts. File:Zvezda_training_module.jpg|Cosmonauts training with the
