Beautiful image! Here's Damia's latest panorama for sol 1996 in circular form.

Curiosity had a short drive on Sol 1998 (time stamps on the downlinked drive images show ~20 minutes. The ground does not appear to have many options for contact science, so they may choose to drive again before the weekend
I'll try to edit this post if more images come down |

A large RMI-ChemCam mosaic was taken on sols 1980 & 1981 (40 photos !) to look at Peace Vallis Channel (on the right part of the mosaic).
Top image was taken by MC100. Color transitions are somewhat weird because of debayering artifacts and JPEG compression.

When I see these images I always wonder about the trade off of putting a super telephoto camera on a rover. Not sure what the numbers in MC40 and MC100 stand for, but with 35mm nomenclature, how about a MC400 or MC800? The camera would probably be used a bit more than the ChemCam because it would give much better images of distant objects and could be in color. I know the next rover is going to have zoom MastCams, but not that wide on the telephoto end. Thoughts? If the aperture were large enough it cold do astronomy. What weight would make a camera a realistic consideration 10 kg 5 kg 2 kg 1kg 0.5 kg? I assume weight is a much bigger constraint than volume.

MC 100 field of view (around 5 degrees square) corresponds roughly to the fov of a 300-400 mm lens on a 35 mm sensor. ("100" is the focal length in mm, but the sensor is smaller than 35 mm so the fov is also smaller). For fixed speed (focal ratio) the volume and weight of the aperture lenses would increase like the square of the focal length, so either the weight gets big or you have to sacrifice speed (and perhaps resolution if you're diffraction limited).

QUOTE (Floyd @ Mar 21 2018, 02:40 PM)  When I see these images I always wonder about the trade off of putting a super telephoto camera on a rover. FWIW, Supercam on M2020 has MSL RMI-like resolution but will be in color; I don't know the specifics but they're probably out there somewhere. There's a lot more color capability on M2020; we did it first, now everybody is doing it. -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.

Sol 1998 Navcam panoramic. We are approaching the bug of 2000. I mean… the 2000th sol ^^ (These sols feels like years for me)
