Possible contributions of Japan to the Habitable Worlds Observatory (HWO)

The Habitable Worlds Observatory (HWO) is NASA's planned flagship space telescope, following the James Webb Space Telescope and the Roman Space Telescope, of which launch is scheduled for the 2040s. The HWO will conduct observations in the ultraviolet (UV) to near-infrared (NIR) wavelength range using a 6-meter-class telescope. One of HWO's science goals is to search for Earth-like exoplanets (including the search for signs of life) using a coronagraph, and will also conduct astrophysical and astronomical observations possible in the UV to near-infrared wavelength range. The HWO is a NASA-led mission with an international partnership. At this moment, Japan is considering contributing to the HWO via science, the coronagraph hardware, and UV hardware. We present possible contributions of Japan to the HWO.
