9:59:59.000,9:59:59.000 The problem is 9:59:59.000,9:59:59.000 00:00when the capsule moves from an elliptical orbit to a parabolic orbit. There's no mathematical formula for that. 9:59:59.000,9:59:59.000 00:09[br]Because we can calculate launch and landing but without this conversion the capsule stays in orbit, we can't bring it back home. 9:59:59.000,9:59:59.000 00:18[br]Maybe we've been thinking about this all wrong. 9:59:59.000,9:59:59.000 00:20[br]How's that? 9:59:59.000,9:59:59.000 00:26[br]Maybe it's not new math at all. 9:59:59.000,9:59:59.000 00:30[br]It could be old math. 9:59:59.000,9:59:59.000 00:32[br]Something that looks at the problem numerically and not theoretically. Math is always dependable. 9:59:59.000,9:59:59.000 00:39[br]For you it is. 9:59:59.000,9:59:59.000 00:47[br]Euler's method. 9:59:59.000,9:59:59.000 00:49[br]Euler's method? 9:59:59.000,9:59:59.000 00:50[br]Yes. That's ancient. But it works. 9:59:59.000,9:59:59.000 00:54[br]It works numerically. 9:59:59.000,9:59:59.000 01:31[br]That's it. 9:59:59.000,9:59:59.000 01:35[br]Let's type it up. 9:59:59.000,9:59:59.000 01:40[br]Huh.
