Radians, of course. Oops!

Using the first formula provided by Keithth I seem to have a problem calculating B. using the formula I get the correct values for A and C: A = 1034.66 C = 5.75X10^{-3} for B I get: (r - r_p) / (r_a - r) = (1738100 - 1718100) / (1758100 - 1738100) = 20000/20000 = 1 \sqrt{1} = 1...

Is there anychance you could work through an example from the equation to help me understand it, this is a bit beyond my maths skills (or lack of)!

Thanks, there's a fair bit of reading up for me to do understand that but I'll give it a go!

That's how I was thinking of doing it. From the radius I think I can calculate all other orbital elements that I would want the sim to display.

Hi all. I'm thinking of writing a program to simulate going from lunar orbit to the surface by providing the program with an initial orbital radius (it will then assume a perfect orbit) and looping through the code until the craft hits the surface. The initial set up of the orbit is easy...

Time for shameless plug #2 in 2 days:P I wrote a tutorial for just what your after a few years ago. It uses TransX so if you wanted to do it with IMFD this isn't for you. However, TransX is a more powerful MFD so its good to get the hang of. Dont be put off by the age of the tutorial as its...

Just like to add a link to my Earth to Mars tutorial using TransX. It says its for an old version of Orbiter but is still usable with the newest edition. Interplanetery Flight Tutorial Its proved popular over the years so perhaps i'll do a 2nd edition! Andy

SOI calculates the radius between two large bodies (eg Earth and Moon) at which the Sphere Of Influence (gravitational field strength) switches from one body to the other.

Teaches you to fly from Earth to Mars using TransX. Primarily for Newbies, but also useful for more advanced users wanting to learn basics of TransX.
