PUNCH - The polarimeter to unify the corona and heliosphere
WFI-1 delivered for integration to PUNCH
WFI FM-1, pictured here in the Bldg 178 clean room fully dressed in MLI after
completing all environmental and performance testing, is ready for integration to the PUNCH spacecraft.
The Southwest Research Institute WFI team have delivered their first flight instrument (WFI-1) to the Integration and Test
team for integration onto a flight PUNCH Observatory! WFI is a wide-field heliospheric imager, similar to an externally
occulted coronagraph with a linear geometry. It will view a 40° wide field-of-view extending from 4.5° to approximately
45° from the Sun. WFI-1 will be integrated to a PUNCH spacecraft later this winter, in preparation for observatory
environmental testing through the spring of 2024. PUNCH is scheduled to launch by early April of 2025.
