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. |

Isn't the martian atmosphere of such low density that not even the strongest storms will move anything more substantial than dust? I recall that's the same reason why gliders aren't feasible for exploration.
