Colorado Ultraviolet Transit Experiment (CUTE) is a small UV space telescope to study selected exoplanets.[1]

It was launched as a rideshare on the Atlas V that launched Landsat 9 on Sept 27 2021.[1] It should operate for at least 7 months and study 10 exoplanets.

CUTE can measure near-UV (255-330 nm) and do low resolution spectroscopy of atmospheric tracers (eg. Fe II, Mg II, Mg I, OH).[2]

The UV sensor is a 2048 x 515 pixel CCD array, with the spectrum lengthwise across the sensor.[3] The 515 pixel width provides tolerance from sensor damage.
