The plume crash plume in the MSL photo is on/over the horizon. The apparent dust cloud in the Perseverance image appears closer than the horizon.

Yes, with the dust-cloud well below the horizon on such a wide-angle view it must be very close.
Remember the first Oppy hazcam shots. We thought they showed a huge outcrop. Turns out it was just a few centimeters high. |

Using the images from MERovingian's link and increasing the contrast, it is clear that the feature is at/over the local horizon.

Such a great start! the new landing system spoiled us with what seems to be perfect placement, so the interactive ESA Jezero map may not even need to relocate their 'Perseverance landing site' pin.. to get the probable skycrane crash plume in just the second downlinked image is more icing on the cake and hopefully there will be more frames to help determine how quickly the plume settles, and not to mention congrats to JPL on returning that meteorite fragment to its original home!

Only one partial that is not a thumbnail. Cropped, curves adjusted and enlarged 200%

I guess there will always be an essential similarity to the immediate vicinity of safe landing sites...

The landing site is likely the white dot. I suspect the "top" horizon in the Rear HazCam images is probably the cliff that defines the delta.

Super achievement...congrats to you Mars's guys and team (would love to be involved in its future exploration).

I'd rather not if you don't mind. Mapping from beyond the grave is not on my bucket list.
EDIT: Darn.. the post I was joking about has been changed! . Phil -------------------- ... because the Solar System ain't gonna map itself.

The landing site is likely the white dot. I suspect the "top" horizon in the Rear HazCam images is probably the cliff that defines the delta. That's my estimate from a hazard map I saw on NASA's livestream. My sources on the mission team have told me that I'm probably within 100 m of the actual landing site (about the width of the dot in all directions), but they're still in the process of refining the position from thumbnails and HiRISE DTMs, probably won't know for sure until data comes down from an MRO pass this evening. Looks like a good early traverse ahead! We're on the edge of the mafic floor unit, the etched floor unit is only a few days' drive away (probably doable within a day if the Ops team really wanted to move that quickly), and a relatively big crater where the rover can look deep into the crater floor materials with only a short detour. |
