Station Go for Spacewalk Ahead of Upcoming Crew Departure

Mission managers have given the go for two astronauts to exit the International Space Station on Wednesday for a six-and-a-half-hour spacewalk. Meanwhile, three Expedition 66 crew members are getting ready for their return to Earth at the end of the month.

Flight Engineers Raja Chari of NASA and Matthias Maurer of ESA (European Space Agency) began Tuesday morning with standard medical checkups the day before their spacewalk. The duo had an ear exam and measured heart and breathing rate, blood pressure, and temperature. Afterward, Chari and Maurer staged their U.S. spacesuits and readied their spacewalking tools inside the U.S. Quest airlock.

During the afternoon, the spacewalking pair were joined by NASA astronauts Kayla Barron and Tom Marshburn for a procedures review with engineers on the ground. Barron and Marshburn will also be on robotics duty commanding the Canadarm2 robotics arm to assist the spacewalkers during Wednesday’s excursion. Chari and Maurer set their spacesuits to battery power at 8:50 a.m. EDT signifying the start of their spacewalk. Their main objective is to install thermal system and electronics components on the outside of the space station. Live NASA TV coverage begins at 7:30 a.m. on NASA Television, the NASA app and the agency’s website.

The next major event at the orbital lab will be on March 30 when NASA Flight Engineer Mark Vande Hei returns to Earth with Roscosmos cosmonauts Anton Shkaplerov and Pyotr Dubrov. The trio will undock from the Rassvet module inside the Soyuz MS-19 crew ship and parachute to a landing in Kazakhstan about three-and-a-half hours later. The two cosmonauts practiced Soyuz descent procedures and loaded cargo and personal items inside the vehicle. Vande Hei, who will land with a NASA-record breaking 355 continuous days in space, focused mainly on science today studying space archeology and glass optics.

The station’s three newest crew members are in their first full week on the orbiting lab and continue their station familiarization activities. Cosmonaut Oleg Artemyev, on his third space station mission, and first time space-flyers Sergey Korsakov and Denis Matveev will spend the next few days getting used to life on orbit.

crew checked in from the airlock requesting go for EMU cable troubleshooting and ISLE prep.  MCC-H gave a go for both.  Late yesterday I heard the crew discussing a damaged cable which may be related to the troubleshooting

The issue is with a power cable in the left armpit of Mathias' suit.  Apparently it is too long or protruding.

The cable is to the glove heater and will be covered in foil since the covering is frayed

SG-1 now in use. Note SG-1 and SG-2 are separated into the left and right audio channels.  SG-1 is always louder and usually has Russian comms...

Mathias was told by the ground he will not have glove heaters and seems confident activity will be enough

NASA TV is Live as Two Astronauts Prep for Spacewalk

Heidi Lavelle Posted on March 23, 2022

NASA Television coverage of today’s spacewalk with NASA astronaut Raja Chari and ESA (European Space Agency) astronaut Matthias Maurer is now underway and also is available on the NASA app, the Space Station blog and the agency’s website.

The crew members of Expedition 66 are preparing to exit the International Space Station‘s Quest airlock for a spacewalk expected to begin about 8:50 a.m. EDT and last approximately six and a half hours.

Chari and Maurer will install hoses on a Radiator Beam Valve Module that routes ammonia through the station’s heat-rejecting radiators to keep systems at the proper temperature. The crew members will also install a power and data cable on the Columbus module’s Bartolomeo science platform, replace an external camera on the station’s truss, and conduct other upgrades to station hardware.

Chari will serve as extravehicular crewmember 1 (EV 1) and will wear a suit with red stripes. Maurer will serve as extravehicular crewmember 2 (EV 2) and will wear an unmarked suit. The spacewalk will be the second of Chari’s career and the first for Maurer. Astronauts Tom Marshburn and Kayla Barron will assist the spacewalkers in and out of their spacesuits and monitor their external activities. Additionally, Barron and Marshburn will be on robotics duty commanding the Canadarm2 robotics arm to assist during the excursion.

Time to move into the crew airlock, where depressurisation will begin. Find out more about the steps that proceed our astronauts' egress in this handy infographic..
