Must be able to work in a fast-paced environment – 17,500 miles per hour, that is.⁣

Astronaut Josh Cassada, pictured here, prepares a roll-out solar array so it can unfurl on the International Space Station (iss) as the orbiting lab flew 262 miles (421 kilometers) off the coast of Namibia.⁣
 ⁣
NASAAstronauts Frank Rubio and Josh Cassada conducted a spacewalk on Thursday, Dec. 22, for seven hours and eight minutes to install the new roll-out solar arrays to upgrade the station’s power system. The new iROSA solar arrays will increase power generation capability by up to 30%, increasing the station’s total available power from 160 kilowatts to up to 215 kilowatts.⁣
 ⁣
Apart from the challenges of working in microgravity, handling 70-100 tools and tethers, spacewalking astronauts also face a wide variety of temperatures. Astronauts experience a wide range of temperatures during a spacewalk. In low-Earth orbit, spacesuits can get to minus 250 degrees Fahrenheit. In the sunlight, they can get as hot as 250 degrees. Because of the spacesuits' multiple thick layers and life support systems, astronauts are protected from the extreme conditions of space.⁣

The space station equipment is white and grey; bronze -colored handlebars line the sides of it. Another piece of space station equipment peeks over the left side of the image.⁣
