NICER Project: Latest Status and Updates

Fast Summary

• Issue with NICER’s Motor: NASA’s X-ray telescope NICER,on the International space station (ISS),paused operations on June 17 due to motor degradation affecting it’s ability to track cosmic objects.
• Daytime Observation Problems: In May 2023, NICER experienced a “light leak” as damage in the telescope’s thermal shields allowed sunlight to interfere with its detectors during orbital daytime. Nighttime observations remained unaffected.
• Spacewalk Repair Efforts: In January, NASA astronaut Nick Hague installed nine patches during a spacewalk to block damaged areas of thermal shields. Post-repair data shows improvements in performance and reduced sunlight interference.
• Reconfiguration Success: NASA reconfigured NICER’s measurement/power units (MPUs) after testing strategies for ignoring light contamination-related resets. Combined efforts restored over 70% of daytime observation capacity by March 12.
• Continued Science Operations: Despite challenges, NICER continues nighttime observations at full capacity while enabling groundbreaking explorations into neutron stars, black holes, and other energetic phenomena.
