On April 18th, 2023, Russian cosmonauts Oleg Novitsky and Pyotr Dubrov began a spacewalk to move the Roscosmos radiator at the International Space Station (ISS). This was the first spacewalk of the year for the Russian space agency, and it was successfully completed on April 19th. Let's take a closer look at this mission and its significance.
Preparing for the Spacewalk
Before the spacewalk, Novitsky and Dubrov had to go through a rigorous preparation process to ensure their safety and success. They had to don their spacesuits and check their communication systems, tools, and tethers. They also had to review their procedures and rehearse their movements inside the ISS's airlock.

Moving the Radiator
The primary objective of the spacewalk was to move the Roscosmos radiator from one location to another on the ISS's Russian segment. This radiator is used to regulate the temperature of the station's systems and equipment. Moving it was necessary to make room for a new science module that will be delivered to the ISS in the near future.
During the spacewalk, Novitsky and Dubrov had to carefully detach the radiator from its current location and maneuver it to the new location using a hand-operated crane. They had to work in coordination with ground controllers and follow a detailed set of procedures to ensure the radiator was secured in its new position.
Other Tasks
In addition to moving the radiator, Novitsky and Dubrov also had to perform other tasks during the spacewalk. They installed a new high-definition camera outside the ISS and retrieved several scientific experiments from the station's exterior.
Eye and Brain Study
While the cosmonauts were outside the ISS, their fellow crew members inside the station were busy with a different task. They participated in an eye and brain study that aims to understand the effects of microgravity on astronauts' vision and cognitive function. The study involves using virtual reality technology to simulate different scenarios and track the astronauts' eye movements and brain activity.
The successful completion of the spacewalk by Novitsky and Dubrov is a testament to their skill and training as cosmonauts. It is also a significant milestone for the Russian space agency as it prepares to welcome a new science module to the ISS. The eye and brain study being conducted by the astronauts inside the station also highlights the importance of understanding the effects of long-term spaceflight on human health and well-being.
