1. Health Checks and Suit Preparations: NASA astronauts Nick Hague and Suni Williams began their day with health exams, measuring vital signs like heart rate, breathing rate, and temperature. They also conducted hearing tests to ensure they were fit for the upcoming spacewalk.
2. Spacesuit Upgrades: The duo installed lithium-ion batteries and tested electrical and communication components on their spacesuits. Flight Engineer Butch Wilmore assisted by preparing cameras for the mission.
3. Spacewalk Details: The spacewalk is scheduled for 8 a.m. EST on Thursday, marking the first of 2025. Hague and Williams will spend approximately 6.5 hours servicing the NICER X-ray telescope, the Alpha Magnetic Spectrometer, and replacing critical hardware like a rate gyro assembly and a planar reflector.
4. Scientific Research: Earlier, Wilmore calibrated genetic sequencing hardware to analyze water samples for bacteria and fungi. NASA Flight Engineer Don Pettit worked on orbital plumbing and processed samples from the Gradient Heating Furnace, which supports semiconductor crystal growth research.
5. Cosmonauts’ Contributions: In the Roscosmos segment, cosmonauts Alexey Ovchinin, Ivan Vagner, and Aleksandr Gorbunov studied microgravity’s effects on blood flow in tiny vessels. They also replaced electronics and serviced plumbing systems.
6. NASA+ Coverage: NASA+ will broadcast the spacewalk live, starting at 6:30 a.m. EST on Thursday.

What Undercode Say:
The preparations for this spacewalk highlight the intricate coordination and advanced technology required to maintain the ISS and conduct cutting-edge research in space. Here’s an analytical breakdown of the key aspects of this mission and its broader implications:
1. The Importance of Spacewalks:
Spacewalks, or Extravehicular Activities (EVAs), are critical for maintaining and upgrading the ISS. They allow astronauts to perform tasks that cannot be done remotely, such as repairing external hardware or installing new instruments. The upcoming spacewalk by Hague and Williams underscores the station’s role as a hub for astrophysics research, with tasks like servicing the NICER X-ray telescope and the Alpha Magnetic Spectrometer. These instruments are pivotal for studying neutron stars and dark matter, respectively, contributing to our understanding of the universe.
2. Health and Safety in Space:
The rigorous health checks conducted by the astronauts are a reminder of the extreme conditions humans face in space. Microgravity can affect cardiovascular health, bone density, and even hearing. By monitoring vital signs and conducting hearing tests, NASA ensures that astronauts are physically prepared for the demands of a spacewalk. This attention to detail is crucial for mission success and crew safety.
3. Technological Advancements:
The use of lithium-ion batteries in spacesuits represents a significant upgrade from older technologies. These batteries are lighter, more efficient, and have a longer lifespan, enabling longer and more productive EVAs. Additionally, the genetic sequencing hardware used by Wilmore to analyze water samples showcases how space technology is advancing to ensure the health and safety of the crew by monitoring the station’s environment for harmful microorganisms.
4. Collaborative Efforts:
The ISS is a testament to international collaboration. While NASA astronauts focus on the spacewalk and scientific experiments, the Roscosmos cosmonauts are conducting their own research, such as studying microgravity’s effects on blood flow. This division of labor allows for a wide range of experiments to be conducted simultaneously, maximizing the station’s scientific output.
5. Public Engagement:
NASA+’s live coverage of the spacewalk is an excellent example of how space agencies are engaging the public. By broadcasting these missions, NASA not only educates the public but also inspires the next generation of scientists, engineers, and astronauts.
6. Future Implications:
The research conducted aboard the ISS has far-reaching implications. For instance, the semiconductor crystal growth experiments could lead to advancements in electronics and materials science. Similarly, the cosmonauts’ studies on blood flow in microgravity could improve our understanding of human health, benefiting both space exploration and medical science on Earth.
In conclusion, the upcoming spacewalk and the ongoing research aboard the ISS exemplify humanity’s commitment to exploring and understanding space. Each mission brings us closer to answering fundamental questions about the universe and paves the way for future exploration, including potential missions to the Moon and Mars. The ISS remains a beacon of international cooperation and scientific achievement, proving that the sky is not the limit—it’s just the beginning.
