Both Chari and Barron had been preparing for the spacewalk for over a week and had readied their spacesuits and placed their spacewalk tools inside Quest. The green signal was given by Nasa after the final procedures review and a conference with specialists on the ground.Nasa has planned for the installation of six ISS Roll-Out Solar Arrays (iROSA) that will soak up the energy of the Sun to provide electrical power for the numerous research and science investigations conducted every day. The new panels will give the aging station a much-needed electrical boost, as demand for experiments and space tourists grows. The new panels will increase the station’s total available power from 160 kilowatts to a maximum of 215 kilowatts.While Chari and Barron will be outside the Space Station, astronauts Thomas Marshburn and Matthias Maurer will help the spacewalkers in and out of their suits and monitor and guide them during the exterior maintenance job. While it is the maiden spacewalk for Chari, it will be the second for Barron.
