99:59:59.999 --> 99:59:59.999
The problem is

99:59:59.999 --> 99:59:59.999
00:00when the capsule moves from an elliptical orbit to a parabolic orbit. There's no mathematical formula for that.

99:59:59.999 --> 99:59:59.999
00:09
Because we can calculate launch and landing but without this conversion the capsule stays in orbit, we can't bring it back home.

99:59:59.999 --> 99:59:59.999
00:18
Maybe we've been thinking about this all wrong.

99:59:59.999 --> 99:59:59.999
00:20
How's that?

99:59:59.999 --> 99:59:59.999
00:26
Maybe it's not new math at all.

99:59:59.999 --> 99:59:59.999
00:30
It could be old math.

99:59:59.999 --> 99:59:59.999
00:32
Something that looks at the problem numerically and not theoretically. Math is always dependable.

99:59:59.999 --> 99:59:59.999
00:39
For you it is.

99:59:59.999 --> 99:59:59.999
00:47
Euler's method.

99:59:59.999 --> 99:59:59.999
00:49
Euler's method?

99:59:59.999 --> 99:59:59.999
00:50
Yes. That's ancient. But it works.

99:59:59.999 --> 99:59:59.999
00:54
It works numerically.

99:59:59.999 --> 99:59:59.999
01:31
That's it.

99:59:59.999 --> 99:59:59.999
01:35
Let's type it up.

99:59:59.999 --> 99:59:59.999
01:40
Huh.
