About this work
NICER engineer Steven Kenyon installs an X-ray detector onto the payload’s detector plate. The detectors are protected by red caps during installation because they are very sensitive to dust and other foreign object debris. The Neutron star Interior Composition Explorer (NICER) is a NASA Explorer Mission of Opportunity dedicated to studying the extraordinary environments — strong gravity, ultra-dense matter, and the most powerful magnetic fields in the universe — embodied by neutron stars.
