ULTRASAT: High efficiency near-UV imaging, coming to a sky near you!

James E. Rhoads, GSFC

ULTRASAT is a dedicated near-ultraviolet imaging mission that is under development in Israel with NASA participation. Its large field of view (~ 200 sq. degrees) and efficient detectors (peak QE ~ 70%) will provide an unprecedented survey efficiency. Key science drivers emphasize time-domain astronomy, including monitoring of stellar explosions and follow-up of gravitational wave events. But ULTRASAT’s planned applications span a much wider range, including solar system studies; exoplanets; stars; galaxies; and cosmology. In this talk I will provide an overview of the spacecraft’s capabilities and its operations concept; and will discuss opportunities for the US community to become involved through an anticipated NASA Participating Scientist Program proposal call.

An illustration of Sun-like star HD 181327 and its surrounding debris disk. The star is at top right. It is surrounded by a far larger debris disk that forms an incomplete ellpitical path and is cut off at right. There’s a huge cavity between the star and the disk. The debris disk is shown in shades of light gray. Toward the top and left, there are finer, more discrete points in a range of sizes. The disk appears hazier and smokier at the bottom. The star is bright white at center, with a hazy blue region around it. The background of space is black. The label Artist's Concept appears at lower left.
