January 2018 NSA Club Meeting

  • Arlington Heights Library 500 North Dunton Avenue Arlington Heights, IL, 60004 United States (map)

NSA member Mark Christensen presents a program on the Neutron star Interior Composition ExploRer (NICER) X-ray telescope that was installed on the International Space Station last summer. Its purpose is to provide very high resolution timing data and energy spectra. While we have a broad understanding of the nature of neutron stars, their internal composition remains largely a mystery. NICER’s secondary objective is to examine the use of soft X-ray emissions as timing beacons for GPS-like navigation in deep space.
