HiRISE Instrument News
Since July 23, 2023, HiRISE observations have lacked data from the RED4 CCD due to a hardware issue, creating a gap in the middle of image products and reducing the color swath to 1 CCD width. We are investigating the hardware issue and may be able to acquire some RED4 data in the future.
