Expedition 61 Commander Luca Parmitano of ESA (European Space Agency) and NASA Flight Engineer Andrew Morgan will begin a spacewalk outside of the International Space Station at about 7 a.m. EST Friday, Nov. 15. NASA Television coverage of the spacewalk will begin at 5:30 a.m.
Watch the spacewalk on NASA TV and on the agency’s website.
The two astronauts will venture outside the International Space Station for the first in a series of complex spacewalks to replace a cooling system on the Alpha Magnetic Spectrometer (AMS), a cosmic ray detector. The upgraded cooling system will support AMS through the lifetime of the space station.
Parmitano and Morgan have spent dozens of hours training specifically for the AMS repair spacewalks. NASA astronauts Christina Koch and Jessica Meir will help Parmitano and Morgan suit up for the spacewalks and will maneuver the Canadarm2 robotic arm to help position the spacewalkers around the AMS repair worksite.
These spacewalks are considered the most complex of their kind since the Hubble Space Telescope servicing missions. The AMS originally was designed for a three-year mission and, unlike Hubble, was not designed to be serviced once in space. More than 20 unique tools were designed for the intricate repair work, which will include the cutting and splicing of eight cooling tubes to be connected to the new system, and reconnection of a myriad of power and data cables. In addition to the overall complexity, astronauts have never before cut and reconnected fluid lines, like those that are part of the cooling system, during a spacewalk.
