I love that Suni Williams (a very-willing!) "hostage" on the ISS (back story -- on her extended stay at the station, here) -- will pitch in to get the job done. Now it is go time -- the live mission is about one week away. Here's the latest from NASA and the ISS:
. . .NASA astronaut Nick Hague will install patches to the agency’s NICER (Neutron star Interior Composition Explorer) X-ray telescope on the International Space Station as part of a spacewalk scheduled for Jan. 16. Hague, along with astronaut Suni Williams, will also complete other tasks during the outing.
NICER will be the first NASA observatory repaired on-orbit since the last servicing mission for the Hubble Space Telescope in 2009.
Hague and other astronauts, including Don Pettit, who is also currently on the space station, rehearsed the NICER patch procedures in the NBL (Neutral Buoyancy Laboratory), a 6.2-million-gallon indoor pool at NASA’s Johnson Space Center in Houston, in 2024. . . .
From its perch near the space station’s starboard solar array, NICER studies the X-ray sky, including erupting galaxies, black holes, superdense stellar remnants called neutron stars, and even comets in our solar system.
But in May 2023, NICER developed a “light leak.” Sunlight began entering the telescope through several small, damaged areas in the telescope’s thin thermal shields. During the station’s daytime, the light reaches the X-ray detectors, saturating sensors and interfering with NICER’s measurements of cosmic objects. The mission team altered their daytime observing strategy to mitigate the effect. . . .
NASA astronauts Hague and Williams will replace a rate gyro assembly that helps provide orientation control for the station, install patches to cover damaged areas of light filters for an X-ray telescope called NICER (Neutron star Interior Composition Explorer), and replace a reflector device used for navigational data on one of the international docking adapters. Additionally, the pair will check access areas and connector tools that will be used for future maintenance work on the Alpha Magnetic Spectrometer.
Hague will serve as spacewalk crew member 1 and will wear a suit with red stripes. Williams will serve as spacewalk crew member 2 and will wear an unmarked suit. This will be the fourth for Hague and the eighth for Williams. It will be the 273rd spacewalk in support of space station assembly, maintenance, and upgrades. . . .
Now you know -- onward, in an incredible moment to be alive and observing these wonders. And. . . Mr. and Mrs. Carter are reunited now. Smile.
