Three Expedition 53 astronauts conducted eye exams Tuesday morning two days ahead of a spacewalk. The crew is also preparing for a pair of upcoming commercial cargo missions.
Commander Randy Bresnik, who is leading all three spacewalks this month, joined his fellow spacewalkers for a periodic eye exam. Bresnik and Flight Engineers Mark Vande Hei and Joe Acaba scanned their eyes using an ultrasound device with guidance from doctors on the ground monitoring the crew’s health.
Paolo Nespoli, from the European Space Agency, did some rearranging inside the Japanese Kibo laboratory module today. He is preparing Kibo for new science gear arriving on a pair of private space freighters in November. Orbital ATK’s Cygnus resupply ship is due to launch mid-November and the SpaceX Dragon is planned to launch at the end of November.
Two astronauts are getting ready for a spacewalk set to begin Thursday at 8:05 a.m. EDT. This will be the first of three spacewalks taking place this month for maintenance at the International Space Station.
The first spacewalk will focus on the removal and replacement of one of the Canadarm2’s latching end effectors (LEE). The second and third spacewalks will concentrate on the lubrication of the LEE and the installation of a pair of external cameras. You can watch all three spacewalks live on NASA TV beginning at 6:30 a.m. here… https://www.nasa.gov/live
Ground controllers are remotely maneuvering the Canadarm2 to the correct worksite today to allow the spacewalkers access to its LEE. The three astronauts are also installing rechargeable batteries on their spacesuits and reviewing their tasks with specialists in Mission Control.
