IXPE Rollout at LC 39A

A SpaceX Falcon 9 rocket with NASA’s Imaging X-ray Polarimetry Explorer (IXPE) spacecraft, rolls out to Launch Complex 39A at NASA’s Kennedy Space Center in Florida on Dec. 7, 2021. IXPE is scheduled to launch no earlier than 1 a.m. EST Thursday, Dec. 9. NASA’s Launch Services Program is managing this launch. NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the IXPE mission. Ball Aerospace, headquartered in Broomfield, Colorado, manages spacecraft operations with support from the University of Colorado at Boulder. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the Explorers Program for the agency’s Science Mission Directorate in Washington. The U.S. Space Force’s Space Launch Delta 45 provides range support for this launch. SpaceX is providing the launch vehicle for this mission. 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.
