Starting a new topic here - hopefully that's OK! Clearly there will be a lot of action around this in the next weeks and months with descent images and HiRISE views of the hardware.

I thought I had posted this map earlier but apparently not. This shows the various landing ellipses in this area. The original plan was for an ellipse oriented NW-SE, but it changed with the different launch date and is now nearly E-W. Note that the ellipse shown in the recent ESA release is the envelope of all ellipses over a given launch period, but the actual landing ellipse for the given launch date is smaller. Opportunity's final landing ellipse is shown for comparison.

Here's the full set of available images of the Schiaparelli parachute. The first 3 are all in late 2016 and show a quick change to the parachute after landing. The last one is from this March and shows a bit more movement, or perhaps parts being covered with dust.

I think all future flight logic systems can WLOG rule out the possibility that a descending lander is below the surface.
