Pesquet and Kimbrough worked separately on their tasks outside the space station, a symbol of worldwide cooperation which has been continuously inhabited by global astronauts for the past 17 years.
With an aim to upgrade the hardware of the International Space Station (ISS), US astronauts will carry out no less than three spacewalks that would go on for 6.5 hours.
Two astronauts on board the International Space Station (ISS) will conduct up to three spacewalks outside it in late March and early April to prepare for the future arrival of USA commercial crew spacecraft and upgrade station hardware.
Pesquet and Kimbrough will work separately for most of the six-and-a-half hour spacewalk as they prepare to install new docking ports for the next generation of commercial spacecraft and do some minor space station repairs and maintenance.
The goal for Friday's outing was to prepare for the installation of the second of two parking spots for space taxis, known as the International Docking Adapters.
According to NASA, further spacewalks are planned for Thursday, March 30, and Thursday, April 6. He was in charge of performing maintenance to the space station, unrelated to PMA-3.
"Going outside is always a gee-whiz moment for me", Kimbrough said in an interview on NASA television this week, adding that it was also "really satisfying" to see Pesquet perform so well on his first spacewalk back in January.
Friday's spacewalk set the stage for a second docking location. Pesquet, who is also a flight engineer was busy the entire spacewalk, while Kimbrough, commander of the station's Expedition 50 crew, had more time to spare. "It's time to get crewmember eyeballs on the area and get a human evaluation to determine whether we have any damage to the system". They've been used to either connect parts of the ISS together or to help spacecraft like the Space Shuttle hook up to the station.
Mr. Pesquet, meanwhile, looked for signs of a small ammonia coolant leak in outdoor plumbing. Once he's done with that, Pesquet will then grease up the end of one of the station's robotic arms, which is in need of some lubrication.
On Sunday, flight controllers in Houston, Texas, will move the old port to provide better clearance for new ships. Each mission will feature two astronauts from Expedition 50.
Shane Kimbrough replaced cameras outside the Japanese Kibo module for a "get-ahead" task after he completed his objectives during his fifth spacewalk on March 24, 2017.
