One Question: What are [math]f_f[/math], [math]f_i[/math], [math]a_f[/math], and [math]a_i[/math]?

If I know that, I can probably reverse-engineer most of page 69. I haven't read the first 65-ish pages, but I found enough information in the general neighborhood of the missing page that I could probably work backwards from those 4 variables.

Probably. :facepalm:

anyway, so far I've got:

[math]k=\frac{1}{cos(f_i)-cos(f_f)}=\frac{-b}{cos(f_f)}[/math]

[math]b=\frac{-1}{k*cos(f_f)}=\frac{cos(f_f)}{cos(f_i)-cos(f_f)}=\frac{cos(f_f)}{2*cos(f_i+f_f)*cos(f_i-f_f)}=\frac{cos(f_f)}{2*cos(f_i+f_f)*cos(f_f-f_i)}[/math]

f_i is the angle between the intercept orbit's periapsis and the point where the intercept burn is made. f_f is the angle between the intercept orbit's periapsis and the intercept point. a_i is the angle between the local vertical and the interceptor's needed orientation at the burn point. reference pg. 67, fig 5-1, for a_f.

They didn't lose the thesis...there is only the one missing page.:facepalm::beathead::suicide:

the missing page contains a confession to faking it all! :lol:

Quoting Charlie Duke: "then why did we fake it 9 times"?

I can't read this as posted on the forum.

How do you lose a thesis written by a guy who was on the first expedition to land on the moon?

We did lose his watch, so we might as well lose his thesis. The former was at least more expensive...

It's an issue depending on your background (theme) color (see http://www.orbiter-forum.com/project.php?issueid=1114)Hmm i can read all the figures just fine on my screen
