Cosmonauts will install a solar radiation experiment on the Zvezda service module

BREVARD COUNTY, FLORIDA – Space Coast Daily, via NASA, will provide live coverage on Wednesday, May 27, beginning at 9:45 a.m. as two Roscosmos cosmonauts conduct a spacewalk outside the International Space Station.

The spacewalk is scheduled to begin at approximately 10:15 a.m. EDT and last roughly five hours.

International Space Station Expedition 74 commander Sergey Kud-Sverchkov and flight engineer Sergei Mikaev will install a solar radiation experiment on the Zvezda service module and remove other science hardware from the Poisk and Nauka modules of the orbiting complex’s Roscosmos segment.

If time allows, the duo will also photograph one of the Progress 94 cargo spacecraft’s Kurs rendezvous antennas, which failed to deploy in March after launch to the space station.

This Roscosmos spacewalk will be the second for Kud-Sverchkov and the first for Mikaev. Kud-Sverchkov will wear a spacesuit with red stripes, and Mikaev will wear a spacesuit with blue stripes.

It will be the 279th spacewalk in support of space station assembly, maintenance, and upgrades.
