NASA’s NICER Telescope Halts Operations Due to motor issue
The Neutron Star Interior composition Explorer (NICER) X-ray telescope, a vital instrument for studying extreme cosmic phenomena, has temporarily suspended operations. A faulty motor impacting its tracking capabilities prompted the pause on June 17, according to NASA.Engineers are currently working to resolve the issue, but the timeline for resuming operations remains uncertain.
NICER’s Mission and Capabilities
Mounted on the International Space Station (ISS) since 2017,NICER plays a crucial role in astrophysics. It’s designed to measure neutron stars, identify black holes, and study active galaxies. Moreover, NICER contributes to mapping potential routes to Mars for future exploration missions.
did You Know? …
Neutron stars are the collapsed cores of massive stars,packing immense density into a small space. A teaspoonful of neutron star material would weigh billions of tons on Earth.
Past Challenges and Repairs
This isn’t the first challenge NICER has faced. In May 2023, the telescope suffered a light leak when thermal shields were damaged, rendering it unusable during daylight. NASA astronaut Nick Hague installed nine patches in January to mitigate the damage, and engineers reconfigured the measurement-power unit to compensate for the remaining light intrusion, allowing operations to resume on March 12. Though, further damage to the thermal shield lead to minimized daytime observations starting may 22.
Pro Tip: …
X-ray telescopes like NICER are essential because Earth’s atmosphere blocks most X-rays from space. Placing them in orbit allows scientists to observe these high-energy emissions without interference.
Key Discoveries Enabled by NICER
Despite these setbacks, NICER has contributed to significant astronomical discoveries. In 2020, observations from NICER and the Nuclear Spectroscopic Telescope Array (NuSTAR) helped scientists analyze a powerful radio wave burst from a magnetar, a type of dead star. This burst released energy equivalent to the sun’s annual output in a fraction of a second, according to research published in *Nature* [[ref]]. The event showcased a laser-like beam rather than a typical explosion.
NASA scientists also utilized NICER and NuSTAR in October 2022 to observe another radio wave burst from the same magnetar.
Timeline of NICER Issues and Repairs
| Date | Event |
|---|---|
| 2017 | NICER deployed on the ISS |
| May 2023 | Light leak develops due to damaged thermal shields |
| January | Astronaut Nick Hague installs patches to repair thermal shields |
| March 12, | NICER resumes normal operations after light leak repair |
| May 22, | Daytime observations minimized due to further thermal shield damage |
| June 17, 2025 | Operations paused due to motor malfunction |
the Future of NICER
NASA engineers are diligently working to address the motor issue and restore NICER to full functionality. The telescope’s continued operation is vital for advancing our understanding of neutron stars, black holes, and other extreme cosmic phenomena. The agency has not yet released a timeline for the telescope’s return to service.

Evergreen Insights: The Importance of X-Ray Telescopes
X-ray telescopes are essential tools for studying the universe because they allow scientists to observe high-energy phenomena that are invisible to optical telescopes. These phenomena include black holes, neutron stars, supernova remnants, and active galactic nuclei. X-rays are emitted by extremely hot and energetic objects, providing valuable data about their composition, temperature, and dynamics.
The growth of X-ray astronomy has revolutionized our understanding of the cosmos, revealing the existence of exotic objects and processes that were previously unknown. Missions like NICER continue to push the boundaries of X-ray astronomy, enabling scientists to probe the most extreme environments in the universe.
