The Imaging X-Ray Polarimetry Explorer (IXPE) is a joint US-Italian mission that enables highly sensitive polarimetry observations of bright galactic and extragalactic sources within the 2-8 keV X-ray band. In this talk, I will focus on the IXPE findings since its launch in 2021, particularly the outcomes derived from X-Ray Binaries featuring stellar mass black holes such as Cyg X-1, 4U 1630-47, and Swift J1727.8-1613. IXPE was used to observe sources in different emission states. The observations can be used to constrain the properties of the accretion disk and the hot accretion disk corona. The results provide insights into the astrophysics of black hole accretion and the underlying plasma physics.
I will close by briefly describing XL-Calibur and DR-TES, two balloon-borne hard X-ray and gamma-ray NASA missions, which will be launched later this year.
