NASA will provide coverage of the upcoming prelaunch and launch activities for the Imaging X-ray Polarimetry Explorer (IXPE) mission, the first satellite dedicated to measuring the polarization of X-rays from a variety of cosmic sources, such as black holes and neutron stars.
IXPE is scheduled to launch no earlier than 1 a.m. EST Thursday, Dec. 9, on a SpaceX Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.
Live launch coverage will begin at 12:30 a.m. on NASA Television, the NASA app, and the agency’s website. On Tuesday, Dec. 7, NASA will hold a payload briefing at 1 p.m. and a prelaunch news briefing at 5:30 p.m.
The IXPE spacecraft includes three space telescopes with sensitive detectors capable of measuring the polarization of cosmic X-rays, allowing scientists to answer fundamental questions about extremely complex environments in space where gravitational, electric, and magnetic fields are at their limits. The project is a collaboration between NASA and the Italian Space Agency.
All media participation in news conferences will be remote except where noted otherwise. For the protection of employees and journalists in the ongoing COVID-19 pandemic, the Kennedy Press Site facilities will be open to a limited number of journalists on a first-come, first-served basis.
