Cosmonauts Complete Spacewalk Preps, More Eye Checks for Rest of Crew

A pair of cosmonauts have wrapped up preparations for Friday morning’s spacewalk to work on the Russian segment of the International Space Station. The other four Expedition 54 crew members continued more eye exams throughout the day on Thursday.

Commander Alexander Misurkin and Flight Engineer Anton Shkaplerov completed a spacewalk procedures review today, finished collecting tools and readied their Orlan spacesuits. The veteran cosmonauts will exit the Pirs airlock around 10:30 a.m. EST Friday for 6.5 hour spacewalk. NASA TV begins its live coverage of the second spacewalk of the year at 9:45 a.m.

The duo will work outside the Zvezda service module to swap out a high gain communications antenna electronics system. If time permits the spacewalkers may also retrieve experiments, photograph the back of Zvezda, reposition a foot restraint and jettison old experiment gear.

The rest of the crew continued working with doctors in real time on the ground today to get a look at their eyes and understand how microgravity affects vision. Astronauts Mark Vande Hei, Scott Tingle and Joe Acaba participated in eye scans using an ultrasound device this morning. Tingle then partnered up with Japanese astronaut Norishige Kanai.

  1. The Heath Deteriorations of The Astronauts after The Long Space Journey maybe is due to The Permanent Distortions of The Blood Circulatory during The Long Space Journey.

    Howdy NASA,
    It sounds the matter to shifting liquids in the human body, because there are a biological sensors working in the human blood circulatory to organize the blood pressure coordinating with the heart`s pulses pressure via organizing the diameter of Blood Arteries explanations in each organ in order to organize the pressure in each organ (with the heart pulses pressure), may the functions of these biological sensors distorts during a microgravity environment that may create unbalances in the blood pressure in the human blood circulatory, and during a long time a space journeys, these distortions will stay a long time as long the time during the long space journey, therefore heath deteriorations of the astronauts after the long space journey is due to the permanent distortions of the blood circulatory during the long space journey, therefore it could result a permanent physical distortions upon blood circulatory system that makes the astronauts keep suffering of a high liquid pressure in some specific organs and even have some effects upon eye health and the heath deteriorations generally.

    Good luck.
