NASA astronauts conduct fifth spacewalk of 2021



NASA astronauts conduct fifth spacewalk of 2021


The spacewalk, which helped with continuous improvements to the orbiting lab, began at 8:14 am ET and ended at 3:01 pm ET, lasting six hours and 47 minutes.

Glover and Hopkins arrived on the space station in November as part of the NASA-SpaceX Crew-1 mission. This will be Glover’s fourth spacewalk and Hopkins ’fifth.

During the spacewalk, Glover was a member of Crew 1 wearing the red striped suit and Hopkins was a member of Crew 2 of the striped suit. Hopkins ’helmet included a high-definition camera for crystal-clear views of his perspective along the spacewalk.

Hopkins and Glover ventilated the first bridge cables in the ammonia system and replaced one and reconnected it to the current cooling system for greater efficiency. Ammonia is part of the station’s cooling system.

Based on the tasks they performed together during their spacewalk on January 27, the two NASA astronauts also connected cables for the Bartolomeo platform of the European Space Agency’s Columbus module and replaced a cable with to an amateur radio system, according to the agency. Bartolomeo can accommodate external payloads.

The spacewalk on March 13 was the 237th global spacewalk in support of the space station.

Some of his other tasks included replacing a wireless antenna set in the first module built in the United States known as Unity, installing a booster on the flexible thermal cover of the air lock where astronauts come and go during spacewalks and routing cables to provide ethernet capabilities for two high-definition. cameras out of the station.

Some of the tasks included in this spacewalk were recovery items that were initially planned for recent spacewalk. However, they were rescheduled for Saturday, so they could be dedicated to the previous space walks to the installation of modification kits that will allow the arrival of new solar panels outside the station later this year. . These matrices will help increase the energy of the space station.

It was the fifth spacewalk of 2021 and the 237th global spacewalk in support of the space station.

NASA astronaut launches stop for nothing, not even a pandemic.  So they have done
The spacewalk took place around the one-year anniversary that many Americans went into quarantine. Hopkins and Glover tackled the moment in one video released by NASA Friday.

“We’re there for each other,” Glover said. “From 250 miles away, I see ourselves united as a people. And while we wait for the vaccines to be deployed and administered, we will be patient and do what is right. Crew-1 called in part for our resistance to the capsule. of the dragon to honor you all and the incredible tenacity you have shown over the past year as you overcame obstacle after obstacle. Keep it up and take care of each other. “

“Yeah, it’s been a tough year,” Hopkins added. “But together we can make sure there’s a brighter year.”

Throughout the pandemic, NASA has been able to safely continue launching astronauts into the space station, including the historic Crew-1 mission carrying Glover and Hopkins, as well as NASA astronaut Shannon Walker and astronaut Japanese aerospace exploration agency Soichi Noguchi.

That follows

The space station is about to see a lot of activity over the next month.

Russian cosmonauts from space agency Roscosmos, Oleg Novitskiy and Pyotr Dubrov, and NASA astronaut Mark Vande Hei will be launched into space from the Baikonur Cosmodrome in Kazakhstan on April 9th.

Vande Hei was selected as an astronaut in 2009 and had his first space flight experience on the space station from September 2017 to February 2018. During his 168 days aboard the station, Vande Hei he made four space walks.

This time, Vande Hei and crew will work on multiple experiments, including studies on Alzheimer’s disease and portable ultrasound devices.

Apollo 11 astronauts quarantined after returning to Earth.  Here is why

Vande Hei’s flight to the Soyuz spacecraft is part of a contract with Houston’s Axiom Space. In return, NASA will essentially save a seat on a future launch of commercial spacecraft in 2023 for a non-NASA space station crew member.

While NASA is working with Boeing and SpaceX to ensure safe transportation of the crew to and from the space station via U.S.-based launches, grabbing a seat on the Soyuz means there will always be at least one member of the U.S. crew on the space station.

After launching from Baikonur in October, Roscosmos cosmonauts Sergey Ryzhikov and Sergey Kud-Sverchkov, and NASA astronaut Kate Rubins will return to Earth on April 17. Crew 1 will return to Earth in April or May.

The return of Crew-1 depends on when Crew-2 is released.

This second rotation with the NASA-SpaceX Crew Dragon spacecraft will include NASA astronauts Shane Kimbrough and Megan McArthur, Japan Aerospace Exploration Agency astronaut Akihiko Hoshide and European Space Agency astronaut Thomas Pesquet.

Crew-2, which could be launched on April 22, will join Crew-1 on the space station before Crew-1 returns to Earth.
