Here is the second spacewalk of the year, the NASA astronauts leads

The is the final stage of work that began in January 2017 to complete the overhaul of the ISS' ageing nickel-hydrogen batteries. There are several other spacewalks planned for the crew members by February end or the beginning of March.

USA space agency NASA says it has scheduled the next launch of SpaceX's Crew Dragon capsule after April 20.

In total, to complete the battery work, 14 spacewalks were needed.

This was the fourth spacewalk in Hopkins' career, and the second for Glover.

The space agency will be streaming the entire spacewalk online. During their second spacewalk, he and astronaut Victor Glover worked to finish a battery upgrade project that was started four years ago.

The astronauts gazed down at Earth and soaked in one last sunset before reentering the space station. NASA astronauts Scott Kelly and Tim Kopra released brake handles on crew equipment carts on either side of the space stations mobile transporter rail vehicle so it could be latched in place ahead of Wednesdays docking of a Russian cargo resupply spacecraft. The International Space Station Program approved the development of lithium-ion batteries to replace the station's aging power storage system back in 2011.

The American astronaut, who has since completed two additional spacewalks, described his first one eight years ago as "a pretty emotional moment", adding, "It can be a little bit nerve-racking, and you're also very excited, right, because this is one of those events that you've dreamed about".

NASA astronauts Mike Hopkins and Victor Glover, both members of the seven-person Expedition 64 crew, ventured outside the space station's Quest airlock at 7:56 a.m. EST (12:56 UTC) Feb. 1, 2021, for U.S. Extravehicular Activity 70.

Hopkins and Glover will also remove a grapple fixture bracket, replace an external camera on the starboard truss, install a new high-definition camera on the Destiny laboratory, and replace components for the Japanese robotic arm's camera system outside the Kibo module, NASA said. Two more spacewalks will be led in about a month to prepare for extra sun powered boards set for conveyance not long from now. That might sound straightforward, but these battery packs are very big, and the process of removal and installation is certainly a challenge. They joined NASA space explorer Kate Rubins and Russian cosmonauts Sergey Ryzhikov and Sergey Kud-Sverchkov, who were at that point on the station subsequent to dispatching in October.

You might be asking yourself why, because it is solar-driven, the space station requires batteries at all. Battery production started in 2014, and the first lithium-ion replacements flew to the station aboard JAXA's Kounotori 6 resupply flight in December 2016.
