Here's another view of Earth and Moon from BepiColombo earlier during the mission (cam_raw_sc_cam3_image_20200304t233732_13_f__t0080 to cam_raw_sc_cam3_image_20200305t233453_28_f__t0100)

BepiColombo flew by Venus today and snapped this black and white shot with its instrumentation in the foreground.

And flyby video , (and here )



Can anyone help me understand what this movement is (in the visible part of the probe - the Mercury Planetary Orbiter’s magnetometer boom)? Photo artifact? A play of light?

below gif's - fragments cut from the "video":

My hypothesis would be that a small part of the spacecraft is blacked out in the darkness of shadow cast by another part of the spacecraft in some frames, and seems to "appear" when it is not in shadow.

Or maybe a specular reflection of venus from a flat, shiny surface that's normally reflecting black? I don't really see any shadows moving near that part.

Similar to the Earth flyby sequence you can see a very thin line light up that part part of the magnetometer boom when lighting is right.
Can be seen much better in this model through camera #2.

Thanks for the suggestions and insights!

Here I found photos of the magnetometer boom (in the laboratory) with the sensor in question (there are actually two such sensors) - unfortunately without the Thermal Shielding.
This rectangular (in the shape of a cube or cuboid) Thermal Shielding is visible in these drawings and probably in this photo. I'm not sure, but maybe it is made of some translucent material (?)

Anyway, since no shadows are actually moving in the Venus flyby video, it seems likely to me that the two flashes seen in the video were caused by the reflection of the Venus disc from two consecutive parallel faces of this Thermal Shielding...

A nice summary of Venus flyby 2's early results (along with near-simultaneous Solar Orbiter data)

Just dropping by to give this thread a little nudge ahead of the upcoming first flyby of Mercury this week on 23:34 UTC, 1 October (01:34 CEST, 2 October). Perhaps I'm not the only one for whom this flyby has kinda crept up on under the radar.

Mercury ahead!

QUOTE
During the flybys it is not possible to take high-resolution imagery with the main science camera because it is shielded by the transfer module while the spacecraft is in cruise configuration. However, two of BepiColomboís three monitoring cameras (MCAMs) will be taking photos from about five minutes after the time of close approach and up to four hours later. Because BepiColombo is arriving on the planetís nightside, conditions are not ideal to take images directly at the closest approach, thus the closest image will be captured from a distance of about 1000 km.
QUOTE
The first image to be downlinked will be from about 30 minutes after closest approach, and is expected to be available for public release at around 08:00 CEST on Saturday morning. The close approach and subsequent images will be downlinked one by one during Saturday morning.
QUOTE
Even though BepiColombo is in Ďstackedí cruise configuration for the flybys, it will be possible to operate some of the science instruments on both planetary orbiters, allowing a first taste of the planetís magnetic, plasma and particle environment.

yeah... i didn't know about it today, until Antdoghalo said something on one of my servers on discord about it
it certainly did creep up under the radar for me too

We have over four years to get ready for BC's actual science operations; this is a useful reminder of what it is that we have to look forward to.

https://ui.adsabs.harvard.edu/abs/2006epsc.......81L/abstract

At global resolution, Messenger has given us a complete map of Mercury that leaves little to improve upon. However, BepiColombo will nonetheless perform a great deal of original science.

why is only a chunk of mercury seen in each frame and not the whole planet?
