Cosmonauts completed their work in open space

June 3, 2021

The egress hatch of the Mini Research Module Poisk is closed, Roscosmos cosmonauts Oleg Novitsky and Petr Dubrov have completed the 48th scheduled spacewalk (EVA-48). During their debut spacewalk they have successfully completed all the work to install equipment on the outer surface of the Russian Segment of the International Space Station. The hatch on the Poisk docking compartment was closed at 16:12 Moscow Time on June2, 2021. The duration of the extravehicular activity was 7 hours and 19 minutes.

It was the second time in the history of the International Space Station that the Russian spacewalk was performed from the docking compartment of the Poisk module. It was launched in 2009, but until November 18, 2020, cosmonauts used for the EVAs the Pirs module, which is currently being prepared for undocking with the ISS. This is the 55-th Russian spacewalk from the ISS, the first in 2021, and the first in the careers of both Roscosmos cosmonauts.

As Oleg Novitsky pointed out earlier, a special feature of the spacewalk was a combination of resource activities, space experiments and preparation of the International Space Station for receiving the new Nauka module, which is to be launched in the summer of this year.

In the 7 hours of normal scheduled activities, Oleg Novitsky and Petr Dubrov replaced an exchangeable panel of the liquid flow regulator in the thermal control system of the functional cargo module Zarya and jettisoned the old panel into space. According to a preliminary assessment by Mission Control Center specialists, the pressurized container departed the International Space Station in the right direction. Within the next 2 or 3 days it is going to burn up during atmospheric re-entry. The operation to replace the regulator in the thermal control system has already been performed three times in the history of the ISS due to expiration of its service life.

In addition to this, the Russian members of Expedition 65 prepared for undocking the Pirs module, which had arrived in 2001. They removed all the external connections between Pirs and the International Space Station: for this purpose, they moved away from the module the upgraded cargo boom M1, re-mated the cables of the Kurs rendezvous system antennas and removed the transfer tether between Russian modules Pirs and Zvezda. Upon completion of this operation Russian specialists confirmed the Kurs system test was successful after re-connection of the connectors. Oleg Novitsky and Petr Dubrov also installed new equipment for Russian science experiments Test and Vynoslivost to study the effects of space environment on various microorganisms and materials.

Todays extravehicular activities were carried out in space suits Orlan-MCS (Modernized, Computerized, Synthetic), one of them with red stripes (Oleg Novitsky), the other one with blue stripes (Petr Dubrov). The previous space walk took place on November 18, 2020. On the ground at the TsNIIMash Mission Control Center (which is a part of State Corporation ROSCOSMOS) the space walk was monitored by specialists of the Lead Operations Control Team for the Russian Segment of the ISS (Rocket and Space Corporation Energia, a part of Roscosmos).

Currently working onboard the International Space Station is a crew consisting of Roscosmos cosmonauts Oleg Novitsky and Petr Dubrov, NASA astronauts Mark Vande Hei, Shane Kimbrough, Megan McArthur, European Space Agency astronaut Thomas Pesquet, and Japan Aerospace Exploration Agency Akihiko Hoshide.
