In the installation and test case of the site No. 254 of the Baikonur cosmodrome, the presence of a nodal module “Pier” of the Russian segment of the International Space Station continues. Today, September 20, 2021, the module in the vacuum chamber was transported at the technical complex to carry out tightness tests.
After completing the autonomous electrical testing program, specialists of the Rocket and Space Corporation “Energy” named after S.P. The queen (part of the state corporation “Roskosmos”) performed the operation of the transit highways of refueling the fuel module “Pier” and its preparation for pneumatic tests. A two-day module test cycle in a 17T523MR vacuum chamber with a helium-air environment in the scanned volumes is intended for objective control of high requirements for the tightness of the product and its on-board systems in ground conditions.
At the same time, electrical tests of the instrument-aggregate compartment of the ship begin at the workplace of the transport cargo ship-module “Progress M-mind”. They provide a cycle of test inclusions of on-board equipment management system and navigation, information and telemetric and universal radiotelemetric systems, orientation systems and radioontrols of orbit, automatics of the thermal mode and combined motor installation.
Universal nodular module “Pier” development and production of the RKK “Energy” them. S.P. The queen is designed to expand the technical and operational capabilities of the Russian segment of the ISS. The removal of the mind “berth” on the near-earth orbit and its docking with the nadarth node of the multi-purpose laboratory module “Science” are planned in November 2021.
