GO BEPICOLOMBO!!! -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

A strange dark streak with greyish "halo" appeared on BepiColombo's High-Gain Antenna (HGA). Unfortunately, the front side of the HGA is rarely imaged by the MCAM3 monitoring camera. In an image taken on 09 Aug 2019 and earlier images everything is fine; then, however, in an oblique view taken on 18 Oct 2020 a dark spot can be seen tentatively at the edge of the HGA dish, the same spot and entire streak is clearly visible on the next image taken on 07 Apr 2021. The dark streak together with the greyish background doesn't seem to change over time when comparing with the most recent available image taken on 09 Dec 2021. Because of thermal control reasons great care was taken in the development and testing of the NV14 ceramic white coating of the HGA and thus coating deterioration by contamination/irradiation processes is unlikely, I think.

A strange dark streak with greyish "halo" ... This is an interesting information. Can you please check what is causing the error "https://archives.esac.esa.int/psa/APP/connector/0/4291/url/cam_raw_sc_cam3_browse_20210809t223002_61_f__t0005.jpeg" cannot be displayed because it contains errors." in all but the third link? Thanks. Fernando |
