The Imaging X-ray Polarimetry Explorer (IXPE) exploits the polarization state of light from astrophysical sources to provide insight into our understanding of X-ray production in objects such as neutron stars and pulsar wind nebulae, as well as stellar and supermassive black holes. Launch has been set for December 9, 2021. Technical and science objectives include:https://ixpe.msfc.nasa.gov/
