Saw the MSL video, which was similar to the MER video. It was awesome. Will try to get a copy

We wanted to learn more about the heatshield performance (we learned a lot!). Ditto Rob, in the thanks-for-dropping-by parade. On the subject of the heat-shield recon, has there been any kind of paper, journal interview, or other public summary of what was learned? Even in a very general sense? Or is that data all still proprietary? -------------------- If Occam had heard my theory, things would be very different now.

Hi ElkGroveDan, Not proprietary, just slow to come out (paper writing is becoming a more of a hobby these days - not enough hours in the day). There were at least two papers published. The summary paper was finally published at the 42nd AIAA Thermophysics Conference last June. In summary we concluded that the char depth of the heat shield material matched our predictions (yea!). We also learned that a piece of a mylar blanket that skirted the heat shield became a "flap" that induced some minor but very noticeable wiggles of the entry vehicle (capsule) during Opportunity's entry just before parachute deployment. The blanket was supposed to fully melt away during entry but we found that part of it did not (it was on Mars still attached to the crumpled heat shield). Its position and size matched our entry dynamic simulations for a flapping flap. Needless to say MSL does not have a blanket covering its heat shield (neither did Phoenix). back to work ... -Rob |
