On the Baikonur cosmodrome, the planned operations of the final stage of the factory control tests (ZKI) of the “Science” module of the Russian segment of the International Space Station under the program of ground-based preparation in the installation and test corps of the site No. 254.
In accordance with the schedule of work on the technical complex, the cycle of pneumatic testing of the “Science” module, intended for accurate control of high requirements for the tightness of large-sized compartments and onboard systems in ground conditions. The module passed the preparatory operations, was filled with helium-air gas mixture and placed in vacuum chamber VK-17T523MR.
Pneumatic tests are calculated for a month, during which the tightness of the body, hatches and docking units will be tested, as well as the functioning of pneumohydrose and outer hydraulic circuits. Then the installation of radiators panels and refueling the temperature of the temperature regime system, as well as the final installation of the ERA European manipulator. After the final testing tests, the extensive program of polygon factory control tests will be completed with the procedure for the material and technical acceptance of the “Science” module by the official customer – the Rocket and Space Corporation “Energy” named after S.P. Queen (part of the state corporation “Roskosmos”).
Further work on the technical complex will be carried out by the South Energy Space Center (the branch of the center of exploitation of landflowing infrastructure facilities in Roscosmos) within the framework of the staff preparation of the product with a calculated duration of 54 days. At this period, it is planned to install solar panels, the placement of goods delivered and control weighing of the module, the assembly of the cosmic head, refueling the fuel components of the module and the overall assembly of the cosmic rocket.
Laboratory Module “Science” – a research module of the Russian segment of the International Space Station, developed by the RSC “Energy” named after S.P. Queen in cooperation with GKNPTS named after M.V. Khrunichev (enters Roscosmos) in order to expand the functionality of the Russian segment of the ISS.
