Astronaut Sunita Williams, along with her colleague Nick Hague, exited the International Space Station (ISS) for a significant spacewalk on Thursday, marking the 91st U.S. spacewalk at the station. This event, known as US Spacewalk 91, is Williams' first in 12 years and her eighth overall, while for Hague, it's his fourth venture outside the ISS.

The spacewalk, lasted approximately six and a half hours, involving Hague, designated as spacewalk crew member 1, in a suit with red stripes, and Sunita Williams as crew member 2, in an unmarked suit. Their mission carried out essential maintenance and hardware replacement tasks.

Here is what you need to know

According to NASA, the duo focused on supporting station upgrades, particularly repairs to the Neutron star Interior Composition Explorer (NICER) X-ray telescope. Their tasks included replacing a rate gyro assembly crucial for station orientation control, installing patches over damaged areas of NICER's light filters, and updating a reflector device on one of the international docking adapters. They also check access points and tools for future maintenance on the Alpha Magnetic Spectrometer.

NASA's next spacewalk to take place on January 23

NASA has also scheduled a subsequent spacewalk for January 23, where Williams, alongside astronaut Barry "Butch" Wilmore, will tackle further tasks. These include removing an antenna assembly, collecting samples for microbial analysis from the exterior of the station, and preparing a spare joint for the Canadarm2 robotic arm.

In related news, the return of Williams and Wilmore to Earth has faced delays due to issues with the Boeing Starliner spacecraft. Initially planned as an eight-day mission, their stay has now extended to ten months. The original return via Starliner was postponed, and now they are set to come back on a SpaceX Dragon capsule, with the launch of SpaceX Crew 10 rescheduled for late March 2025.

Williams expressed her longing to return home, highlighting the extended time away from family, but also emphasized the importance of the work they are accomplishing on the ISS. NASA's decision to delay reflects a commitment to astronaut safety, allowing more preparation time for the SpaceX Dragon spacecraft.

This spacewalk not only underscores the ongoing maintenance required to keep the ISS operational but also highlights the enduring spirit and dedication of astronauts like Williams and Hague in advancing space exploration.
