Summary:
- Astronauts on the International Space Station (ISS) conducted a spacewalk to repair the Neutron star Interior Composition Explorer (NICER) instrument, which studies X-ray emissions from neutron stars and black holes.
- During the spacewalk, the astronauts also inspected the Alpha Magnetic Spectrometer (AMS), a cosmic ray detector that has been operating on the ISS since 2011.
- The successful completion of these tasks demonstrates the ongoing maintenance and upgrades performed by astronauts to keep the scientific instruments on the ISS operational and collecting valuable data about the universe.
