Eye Checks and Cargo Ops Ahead of Thursday Spacewalk

Astronaut Joe Acaba
Astronaut Joe Acaba calculates his mass inside the Columbus laboratory module using the Space Linear Acceleration Mass Measurement Device (SLAMMD). The device generates a known force against a crew member mounted on an extension arm with the resulting acceleration used to calculate the subject’s mass.

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.

Station Crew Gearing Up for Three October Spacewalks

Astronauts Richard Arnold and Joseph Acaba
Astronauts Richard Arnold (bottom) and Joseph Acaba are pictured during a spacewalk in March of 2009. The duo were visiting the space station as STS-119 mission specialists aboard space shuttle Discovery.

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.

NASA TV is broadcasting a live briefing at 2 p.m. today describing what will take place during the three spacewalks planned for Oct. 5, 10 and 18. NASA astronauts Randy Bresnik and Mark Vande Hei will go outside for the first two spacewalks. NASA astronaut Joe Acaba will join Bresnik for the third and final spacewalk.

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.
