NASA TV Goes Live Wednesday for First Spacewalk of 2020

Spacewalkers Christina Koch and Jessica Meir are pictured during their first spacewalk together that lasted seven hours and 17 minutes on Oct. 18, 2019.

Expedition 61 Flight Engineers Christina Koch and Jessica Meir of NASA will begin a spacewalk outside of the International Space Station Wednesday, Jan. 15.

Live coverage of the spacewalk will begin at 5:30 a.m. EST on NASA Television and the agency's website.

This is the first of two battery replacement this month. Meir and Koch will replace nickel-hydrogen batteries with newer, more powerful lithium-ion batteries for the power channel on one pair of the station's solar arrays. The batteries were transported to the station in September aboard the Japanese H-II Transfer Vehicle.

The spacewalking work continues the overall upgrade of the station's power system that began with similar battery replacement during spacewalks in January 2017. In October, Koch and Meir replaced a failed power charging component, also known as a battery charge-discharge unit (BCDU). The BCDU regulates the charge to the batteries that collect and distribute solar power to the orbiting lab's systems.

Expedition 61 - Spacewalk EVA 62 Animation

NASA Video

14 янв. 2020 г.

EVA Officer Sandy Fletcher narrates an animation showing Expedition 61 Flight Engineers Jessica Meir and Christina Koch of NASA teaming up for their second spacewalk together. They venture outside the Quest airlock of the International Space Station for a spacewalk to continue the replacement of aging nickel-hydrogen batteries with new lithium-ion batteries on the port truss of the orbital outpost. The spacewalk is the third in a series of four spacewalks to upgrade the station's power systems on the port truss that began with two days of work outside the station last October. It is the 225th spacewalk in support of space station assembly and maintenance, the second spacewalk in Meir's career and the fifth for Koch.

Смотрю сейчас EVA по NASA TV на Ютубе. Думал в записи трансляция, ан нет, таки в прямом эфире. Давно не смотрел выход в открытый космос. Как я понял, прогулку по вакууму осуществляют женщины. Успешного выполнения работы!

Two NASA astronauts switched their spacesuits to battery power this morning at 6:35 a.m. EST Expedition 61 Flight Engineers Christina Koch and Jessica Meir are venturing out into the vacuum of space for about six-and-a-half hours to finish replacing nickel-hydrogen batteries with new lithium-ion batteries that store and distribute power generated by the station's solar arrays on the station's port truss. The lithium-ion batteries provide an improved power capacity for operations with a lighter mass and a smaller volume than the nickel-hydrogen batteries.

Watch the spacewalk on NASA TV and on the agency's website.

Meir is designated extravehicular crew member 1 (EV 1), wearing the suit with red stripes, and with helmet camera #11. Koch is designated extravehicular crew member 2 (EV 2), wearing the suit with no stripes, and her helmet camera is labeled #18.

Commander Luca Parmitano of the European Space Agency (ESA) and NASA Flight Engineer Andrew Morgan will assist the spacewalkers. Morgan will control the Canadarm2 robotics arm and Parmitano will provide airlock and spacesuit support.
