In case anyone doesn't know the 22nd MEPAG meeting is going on March 17th and 18th.

On the presentations posted for the first day there is one titled "Mars Sample Return (three element architecture)." On the 5th slide it states that during to the "Team X" study, the aeroshell was increased in diameter from 4.5m to 4.7m in order to accommodate both MAX-C and ExoMars together. I took a look at the specifications for the Atlas 5 launch vehicle and found on page 6-4 and 6-21 that the maximum diameter of the payload bay was 4.572m.

Is it possible to fit a 4.7m aeroshell in a 4.572m payload bay? I know this mission is still in the early planning stage and that these numbers should be taken with a huge grain of salt; but this looks like a pretty big oversight. huh.gif

Based on Jim Green's presentation to the PSS, MAX-C and ExoMars will be combined into one rover. Still will use skycrane for descent and landing, still will cache samples for return and the goal is to drill below the surface.
