Colorado Ultraviolet Transit Experiment


Colorado Ultraviolet Transit Experiment is a small UV space telescope to study selected exoplanets.
It was launched as a rideshare on the Atlas V that launched Landsat 9 on September 27, 2021. Designed to operate for at least 8 months and study 10 exoplanets, CUTE remains operational as of December 2023, 27 months after launch. The spacecraft is expected to remain in orbit until 2027.
CUTE can measure near-UV and do low resolution spectroscopy of atmospheric tracers.
The UV sensor is a 2048 x 515 pixel CCD array, with the spectrum lengthwise across the sensor. The 515 pixel width provides tolerance from sensor damage.
