STUDIO
(for Stratospheric UV Demonstrator of an Imaging Observatory)
is a planned balloon-borne 0.5-meter ultraviolet (UV)reflector telescope.
A short test flight from Sweden was planned for 2023 or 2024,
with plans to observe from an altitude of 37 km in further flights.
As of 1/2025, I find no reports of a completed test flight or current
status, and suspect the test flight was delayed, on hold, or canceled.
