SUMMARY:The Colorado Ultraviolet Transit Experiment: Chasing Big Planets with a Small Satellite
DESCRIPTION:NASA Small Spacecraft Systems Virtual Institute’s\nCommunity of Practice Webinar Series\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nJoin us on  Wednesday\, April 12\, 2023\, 10:00AM-11:00AM PT for a webinar by Kevin France.\n\nLaboratory for Atmospheric and Space Physics (LASP) at the University of Colorado Boulder\n\n\nAtmospheric escape is a process that affects the structure\, composition\, and evolution of many planets. The signatures of this escape are detectable on close-in\, gaseous exoplanets orbiting bright stars\, owing to the high levels of extreme-ultraviolet irradiance from their nearby parent stars. The Colorado Ultraviolet Transit Experiment (CUTE) is a 6U CubeSat mission designed to take advantage of the near-ultraviolet stellar brightness distribution to conduct a survey of the extended atmospheres of nearby close-in planets. The CUTE payload is a near-ultraviolet (2487 – 3376 Ang) spectrograph fed by a rectangular\, Cassegrain telescope (206 mm x 84mm); the spectrogram is recorded on a back-illuminated\, UV-enhanced CCD. CUTE was launched into a polar\, low-Earth orbit on 27 September 2021 and has been conducting this survey following an on-orbit commissioning period. An overview of the CUTE mission will be presented\, including its motivation and development path. The presentation will conclude with on-orbit science data and observations of excess NUV absorption on short-period planets acquired as part of CUTE’s science program.\n\nS3VI encourages the community to submit questions before the webinar to enable more directed responses. Please send questions to: Craig.D.Burkhard@nasa.gov
