2, all female space walks included
The three space walks are to be conducted in January by four astronauts. They will venture outside the International Space Station to complete battery upgrades and finalize repairs to an invaluable cosmic ray detector.
Jessica Meir and Christina Koch (Expedition 61 – Flight Engineers) of NASA are scheduled for Wednesday, Jan. 15, and Monday, Jan. 20. The two women will be replacing nickel-hydrogen batteries with new lithium-ion batteries. These batteries store power generated by the station’s solar arrays on the station’s port truss.
NASA astronaut Andrew Morgan and space station Commander Luca Parmitano of ESA (European Space Agency) will venture out of the space station Saturday, Jan. 25. The two men will finish installing the Alpha Magnetic Spectrometer’s (AMS) new cooling apparatus and lines. This begun in November and December. The men will verify they are ready for use.
This will mark Meir’s second and third spacewalk. She will be extravehicular crew member 1 (EV1) for both spacewalks. Koch, will be extravehicular crew member 2 (EV2). She will be performing the fifth and sixth spacewalks of her career.
Morgan, will be EV1 for the AMS spacewalk and Parmitano, will be EV2. He performed the three previous spacewalks to repair the spectrometer. The spectrometer is searching for dark matter and antimatter in the universe. It uses the station’s unique location and capabilities for scientific research.
These will be the 225th, 226th and 227th spacewalks in support of space station assembly and maintenance.
