The NICER/SEXTANT experiment was launched on June 4 aboard the Dragon Spacecraft headed for the International Space Station.  While the primary goal of NICER is science, it also offers the possibility of testing new forms of technology. For instance, the instrument will be used to conduct the first-ever demonstration of autonomous X-ray pulsar-based navigation. As part of the Station Explorer for X-ray Timing and Navigation Technology (SEXTANT), the team will use NICER’s telescopes to detect the X-ray beams generated by pulsars to estimate the arrival times of their pulses
