Reddit reviews Orbital Mechanics for Engineering Students (Aerospace Engineering)

Here's the book my class has used this semester. Interplanetary mission planning is it's own chapter. It's more straightforward than it seems once you're comfortable working with orbital mechanics.

For anyone who is interested in orbital mechanics simulations I've thrown together a very simple MATLAB function that will propagate an orbit in the earth centered earth fixed (ECEF) frame for a desired amount of time from any two line element set (TLE). This propagator assumes only earth's gravity, no perturbations although adding some, like drag, would be a good first project.


The MATLAB function is here:
[Earth_Orbit.m]
(http://pastebin.com/uH8DQWnR) (While needed all the code after line 50 is just to transform the TLE into a state vector so if you're looking to get started don't worry about that too much)

An example of a TLE:
ISS.txt (This one is for the ISS, find a whole bunch at http://www.heavens-above.com/)

You'll also need this lookup table for the Earth's neutation data:
nut80.dat


To use simply save the first pastebin as Earth_Orbit.m the second as ISS.txt and the third as nut80.dat. Put them in the same directory and point MATLAB to that directory. Call Earth_Orbit with the filename of your TLE and the time (sec) you want to see the orbit for.


Example:
Earth_Orbit ('ISS.txt',86400)
This shows the orbit of the ISS for 1 day. Note the ground track shown on the earth model in the output figure isn't correct since the texture is not applied in the correct direction (I think its off by pi but I'm not sure).


If you want to know more I suggest Orbital Mechanics for Engineering Students by Curtis to get started and Fundamentals of Astrodynamics and Applications by Vallado for a more in depth treatment. Be warned even if you're planning on doing relatively simple stuff you're probably going to need to know calculus to get started modeling.


Good Luck!

Howard Curtis has a great book. You will be taught basic orbital calculations (speed, position, other orbital characteristics), and then move on to orbital maneuvers and patched conics. The book also introduces elements of rendezvous. I recommend the use of some software for any sort of orbital mechanics simulations and calculations. MATLAB is an easy tool to use If you familiarize yourself with the ode45() tool. It uses a runga kutta 45 approximation scheme to do the differential equation calculations.

I love SMAD for spacecraft design! My go-to for orbits stuff (my professional specialty) is "orbital mechanics for engineering students" (http://www.amazon.com/gp/aw/d/0080977472?pc_redir=1396560153&robot_redir=1$ and the next one is "fundamentals of astrodynamics and applications" (http://www.amazon.com/gp/aw/d/1881883140?pc_redir=1396676486&robot_redir=1).

> I gotta look at some orbital mechanics books

If you really want to go through with that I highly recommend "Introduction to rocket science and engineering". It goes reasonably into depth but is still accessible with a decent highschool math and physics background. Besides orbital mechanics it covers the basics of pretty much all aspects of rocket science (history, thermodynamics, orbital mechanics, propulsion elements etc.) It is a bit pricey though, you probably want to find it somewhere cheaper.

If you're a bit more advanced (primarily in math) you could also checkout "Fundementals of astrodynamics" which is nice and cheap or "Orbital Mechanics for engineering students" if you really want to make it your job.

I am a mechanical engineer by trade but I am really interested in spaceflight and orbital mechanics so in the past months I have been catching up with those books.

BMW (the book above) is the standard intro astrodynamics book. BMW was updated though and I think the following modern book is a great upgrade to an intro book.

Ok the best place to start is always the bible of rocket science
https://www.amazon.com/Rocket-Propulsion-Elements-George-Sutton/dp/0470080248


also this is a great book about overall design

Other than rocket engines and structures it would be

https://www.amazon.com/Fundamentals-Astrodynamics-Dover-Aeronautical-Engineering/dp/0486600610/ref=pd_sim_14_1?_encoding=UTF8&pd_rd_i=0486600610&pd_rd_r=NV7BKDVSN225K69DY2JR&pd_rd_w=m3KtM&pd_rd_wg=XqmQL&psc=1&refRID=NV7BKDVSN225K69DY2JR

After reading that book cover to cover you can branch into multiple aspects of aerospace engineering.

There are also less formal and fun books like https://www.amazon.de/Ignition-informal-history-liquid-propellants/dp/0813507251
or
https://www.amazon.com/History-Liquid-Propellant-Engines-Library/dp/1563476495/ref=pd_sim_14_63?_encoding=UTF8&pd_rd_i=1563476495&pd_rd_r=NV7BKDVSN225K69DY2JR&pd_rd_w=m3KtM&pd_rd_wg=XqmQL&psc=1&refRID=NV7BKDVSN225K69DY2JR

Same here! Unlike others, though, this is the book we are using for astrodynamics.

that book is dense!! 700 pages, 600 is advance math and formulas. but it does explain everything
