Upcoming Spacewalks on the International Space Station
NASA astronaut Sunita Williams is set to embark on an important spacewalk on January 16, 2025. Alongside fellow astronaut Nick Hague, she will step outside the Quest airlock to tackle urgent repairs to the Neutron Star Interior Composition Explorer (NICER) X-ray telescope.
The NICER telescope has recently encountered serious issues affecting its crucial measurements. Since May 2023, damaged thermal shields have allowed sunlight to infiltrate the system, resulting in the saturation of X-ray detectors and hampering scientific observations. In response, NASA has devised innovative pie-shaped patches aimed at blocking the interfering light and restoring functionality to NICER.
This upcoming mission marks a historic moment as it will be the first occasion astronauts have serviced an X-ray telescope in orbit, akin to past repair missions of the Hubble Space Telescope. On top of the critical NICER repairs, a second spacewalk is planned, where astronauts will remove outdated radio communication equipment and gather microbial samples from the ISS’s exterior.
These missions are part of broader research efforts focused on enhancing fire safety in space and understanding the effects of weightlessness on physical exercise. As NASA continues its mission to safeguard scientific operations aboard the International Space Station, these repairs highlight the unwavering commitment to advancing our research capabilities in space.

Upcoming Spacewalks on the International Space Station
NASA is gearing up for an unprecedented series of spacewalks on January 16, 2025, led by astronauts Sunita Williams and Nick Hague. Their mission will focus on essential repairs to the Neutron Star Interior Composition Explorer (NICER) X-ray telescope, following significant operational challenges since May 2023.
# The Importance of NICER and its Challenges
NICER has faced serious issues due to damaged thermal shields that have compromised its ability to measure X-rays effectively. The infiltration of sunlight has resulted in the saturation of its X-ray detectors, significantly hindering its scientific capabilities. In response, NASA has developed innovative solutions, including pie-shaped patches designed to block sunlight and restore the NICER’s functionality.
# Historic Nature of the Spacewalk
This mission is particularly groundbreaking as it will mark the first time astronauts service an X-ray telescope in orbit, paralleling the notable repair missions performed on the Hubble Space Telescope. This not only highlights the advancements in space technology but also underscores NASA’s commitment to maintaining and enhancing scientific instruments that provide invaluable data about the universe.
# Additional Objectives of the Spacewalk
In addition to the NICER repairs, Williams and Hague will engage in a second spacewalk aimed at removing outdated radio communication equipment and collecting microbial samples from the exterior of the International Space Station (ISS). This aspect of the mission is integral to ongoing research focused on fire safety in space as well as understanding the long-term effects of microgravity on human health.
# Pros and Cons of Spacewalk Missions
Pros:
– Direct servicing of scientific instruments enhances mission lifespan and capabilities.
– Opportunity to gather data on microbial life in space, contributing to astrobiology research.
– Helps maintain communication systems vital for ISS operations.
Cons:
– Risks associated with extravehicular activities (EVAs), including exposure to space hazards.
– High costs related to the execution of spacewalks and technical support.
# Insights into Future Missions
As NASA continues to prioritize the enhancement of its research capabilities at the ISS, these important repair missions serve as a foundation for future explorations. The success of repairing instruments like NICER could pave the way for more ambitious endeavors, including future planetary missions and broader astrophysical research.
