MOSCOW (Roscosmos PR) — Specialists at Khrunichev (part of Roscosmos State Corporation) completed the vacuum tests of a new Russian Nauka (“Science”) module of the International Space Station.

The module was tested by the most objective control method for compliance with the specified characteristics in conditions close to operational. Vacuum tests confirmed the requirements for the standard operation of all systems of the Nuaku module. 

The performance check of all subsystems of the module responsible for the operation of the propulsion system, the temperature control system was carried out, the tightness of the hull and airlock was confirmed, the tightness and performance of the docking units and airtight hatches, as well as a number of related systems, were verified.

Currently, the specialists of the rocket and space plant are preparing the module for shipment to the Baikonur Cosmodrome, where the control tests will be continued before its launch to the International Space Station.

The development of the Science module began more than 20 years ago, based on the backup of the Zarya module – FGB-2. The availability of the module has been repeatedly postponed, and therefore some of its elements needed to be modernized. Subsequently, the module was called the Multipurpose Laboratory Module (MLM).

In accordance with the current plans of the Roscosmos State Corporation, which took special control of the implementation of the ground-based testing program for the Nauka module by rocket and space specialists, it should be launched to the International Space Station in 2021.
