What in your opinion, was the hardest concept of space flight, when you where learning the physics behind it.
Remembering to take time to eat and sleep.:blink:What in your opinion, was the hardest concept of space flight, when you where learning the physics behind it.
When I started learning about orbital dynamics, I tried to do an LEO to moon maneuver with the standard DG.
Using a paper, pen and a scientific calculator. No orbiter instruments (besides the hud, which I've only used to guesstimate the direction I needed to burn in). I did the whole mission in realtime, planning my sleep schedule and computing time to coincide with the course correction burns. I ended up arriving only 17 minutes ahead of schedule and 1,3 degrees out of plane for a landing on brighton beach, which I corrected over the next few orbits and landed.
I think I still have all the paper I used for that stored somewhere (around 30 A4 pages of calculations, sketches and random doodles)...might take some photos and upload if I can find it.

Impressive... You see a career as a astronaught?

Not an astronaut (until a ride to orbit costs less than I can realistically make in 2 years), but I'm studying aerospace engineering.
Interplanetary travel (which I still can't do)![]()

The hardest thing I find is de-orbit. I've been trying to get my head around the physics and maths involved in calculating a de-orbit burn (when, where, how long for, what angle, etc...) and I'm getting nowhere fast!![]()
rendevouzing, never been able to quite get the hang of that, though interplanetry travel is no problem

Not sure if these are any help... http://www.flytandem.com/orbiter/tutorials/index.htmAnyone have a good TransX tutorial?
