Cosmonauts Begin First in a Series of Spacewalks for Station Maintenance

Cosmonauts Begin First in a Series of Spacewalks for Station Maintenance

Spacewalkers Prokopyev and Petelin opened the hatch of the Poisk airlock at 9:39 a.m. EST today, beginning their spacewalk.
Spacewalkers Prokopyev and Petelin opened the hatch of the Poisk airlock at 9:39 a.m. EST today, beginning their spacewalk.

Expedition 68 Commander Sergey Prokopyev and Flight Engineer Dmitri Petelin, both of Roscosmos, began a spacewalk at 9:39 a.m. EST to prepare hardware on the Rassvet module for installation on the Nauka multipurpose laboratory module by opening the hatch of the Poisk docking compartment airlock. Coverage of the spacewalk continues on NASA Television, the NASA app, and the agency’s website.

The duo is preparing a radiator on Rassvet for its move to Nauka.

Prokopyev is wearing a Russian spacesuit with red stripes, while Petelin is wearing a Russian suit with blue stripes. This is the third spacewalk in Prokopyev’s career, and the first for Petelin. It is the tenth spacewalk at the station in 2022 and the 255th spacewalk for space station assembly, maintenance, and upgrades.

NASA Television coverage is underway of today’s spacewalk with Roscosmos cosmonauts to prepare hardware on the Rassvet module for installation on the Nauka multipurpose laboratory module. Coverage of the spacewalk is on NASA Television, the NASA app, and agency’s website.

Expedition 68 Commander Sergey Prokopyev and Flight Engineer Dmitri Petelin, both of Roscosmos, will prepare a radiator on Rassvet for its move to Nauka.

Prokopyev and Petelin will exit out of the Poisk module about 9:20 a.m. EST to begin the approximately seven-hour excursion. Prokopyev will wear a Russian Orlan spacesuit with red stripes, while Petelin will wear a Russian Orlan suit with blue stripes.

This will be the third spacewalk for Prokopyev and the first for Petelin. It will be the tenth spacewalk at the station in 2022 and the 255th spacewalk for space station assembly, maintenance, and upgrades.

Cosmonauts Prep for Thursday Spacewalk, Dragon Targets Monday Launch

Cosmonauts Prep for Thursday Spacewalk, Dragon Targets Monday Launch

Two Roscosmos cosmonauts are finalizing their preparations for a spacewalk on Thursday for hardware transfers and electronics connections on the International Space Station. Meanwhile, two NASA astronauts are cleaning up after a spacewalk on Tuesday readying the orbiting lab for a pair of rollout solar arrays to be installed beginning at the end of the month.

Station Commander Sergey Prokopyev and Flight Engineer Dmitri Petelin are in final preparations for Thursday’s spacewalk set to begin at 9:20 a.m. EST to prepare a radiator and an airlock for installation on the Nauka multipurpose laboratory module. Roscosmos Flight Engineer Anna Kikina will operate the European robotic arm from inside Nauka and assist the duo working in the microgravity environment in their Orlan spacesuits. NASA TV will begin live coverage of the spacewalk at 9 a.m. on the agency’s app and website.

NASA Flight Engineers Josh Cassada and Frank Rubio spent seven hours and 11 minutes working outside the orbiting lab on Tuesday in their Extravehicular Mobility Units (EMUs), or spacesuits. The duo assembled a mounting bracket on the station’s starboard truss structure where new rollout solar arrays will be installed on upcoming spacewalks before the end of the year.

Today, the duo along with fellow Expedition 68 Flight Engineers Nicole Mann of NASA and Koichi Wakata of the Japan Aerospace Exploration Agency (JAXA) called down to mission controllers and discussed Tuesday’s space activities. Cassada and Mann also partnered together refilling spacesuit water tanks and powering down suit components. Mann then joined Rubio collecting spacewalk hardware and suit cameras for sharing with the cosmonauts who will conduct the next spacewalk.

Meanwhile, SpaceX is targeting the launch of its Dragon cargo craft atop the Falcon 9 rocket to the space station at 4:19 p.m. on Monday. Dragon will take a day-and-a-half-long trip to the station carrying the next pair of rollout solar arrays, new science experiments, station gear, and crew supplies. It will dock automatically to the Harmony module’s forward port Wednesday, Nov. 23, at 9:43 a.m.
