I have a question arising from the recent surface images acquired by the Parker Solar Probe (but best discussed in this section, I think, if anyone has comments). Would a camera with similar specifications to WISPR but located on Earth or in Earth orbit be able in principle to image the night-side surface? It presents quite a large target when suitably placed and I imagine some sort of coronagraph arrangement could be used to exclude light from the sunlit crescent.

And here's the same from Venera 14 Camera 1, taking the three usable frames for this. It looks like there was a dramatic removal of dust between two of the frames that also perturbed the... debris thing(?) near the centre of the frame. There is only one usable frame from the Venera 14 Camera 2, so I will not attempt it on the other side. It doesn't look like any dust was kicked up anyway, being the famous "smooth slab" image.
Has this been noticed before? I did some googl'ing around and found Garvin 1981 and Greeley & Arvidson (1990) which talk about dust kicked up by the landers, but I didn't read anything on visual confirmation of dust being moved by wind. -------------------- -- Hungry4info (Sirius_Alpha)

This is the first time I can see any movement on the surface of Venus! Really amazing - after so many years you can still discover something new in such old photos. The gusts of wind had to be strong enough to blow away the dust/sand that was lying on the lander's aerodynamic ring (sand/dust that fell on the ring when the probe landed). PS Do you have the option to use slightly larger pictures for these animations? And what exactly is this "debris thing(?) near the centre of the frame" ? Damaged camera cover? |
