Now that the 'boop' has been completed (with spectacular success!), we'll move the discussion to here for subsequent mission events.

Still, the tracking and calculations are astoundingly accurate.
Remember, this re-entry was purely ballistic without any steering. --Bill -------------------- |

The issue was the main chute opened at 20,000 ft instead of the planned 5000 ft. That's going to change landing point quite a lot, right ?

The issue was the main chute opened at 20,000 ft instead of the planned 5000 ft. That's going to change landing point quite a lot, right ? Nominally, no. By the time the main chute is deployed, the capsule is descending vertically, relative to the air. so unless there is a 'preferred' wind direction, the nominal landing point wouldnt move much, but the time for (assumed random) winds would increase. Hence the predicted ellipse would grow in size, but its center would not move. If you know the prevailing wind (e.g. as we do on Titan), then a prolonged descent does move the ellipse center downwind. |
