ULTRASAT scientific payload: current status and as-built performance

On demand | Presented live 17 June 2024

Abstract

ULTRASAT is a spaceborne near UV telescope with an unprecedentedly large field of view (200 squared degrees) and UV sensitivity. The mission, led by the Weizmann Institute of Science and the Israel space agency in collaboration with DESY (Helmholtz foundation, Germany) and NASA (USA), is expected to be launched to a geostationary orbit in late 2026. The mission payload is currently going through assembly, integration and testing, with all critical elements manufactured and tested. In the following talk I will describe in detail the various challenges encountered, those we expect to encounter during operation, and our mitigation plan. I will emphasize topics such as cleanliness and contamination, optics qualification and stray light testing. Finally, I will present the expected performance based on as-built data.
