General Question Direct to Mars: Another cheap flight?

[Astro SG Wise]

I am bad at IMFD and TransX, and I am wondering if the Direct to Mars addon is a simple switch on the engines and burn way to get to Mars. Do I need directional help?

No. You still need to be capable of doing a Hohmann transfer. Direct just means a much simpler mission strategy than multiple landings and transfers.

This tutorial is a little bit old, but still the best IMHO

I believe it did explain how to do a round trip to mars.

Mars Direct is a mission plan developed a few years back that proposed a specific mission plan that would allow a mars landing with only one launch, instead of a more complex approach involving on-orbit assembly. It still would have used a hohmann transfer, or a fairly close transfer.

I think the addon scenario you are looking at involves using a NTR from Earth orbit to do a flight to mars using what is called a brachistochrone trajectory, which involves expending more delta v to make the transfer as fast as possible. Brachistochrone transfers are much more challenging to execute in Orbiter than a simple hohmann transfer due to the way most of the interplanetary nav tools are set up (although it might be easier in IMFD, I dont know)

Your best bet is to read the documentation for TransX found in the Orbiter docs folder and experiment with interplanetary transfers a bit.

Best of luck, and dont forget to Hail the Probe!

Cool info on the trajectory terminology, but I understand now, and it makes sense, that it would be harder than it sounds.

I know this is random, but I deleted practically all of my doc files, because I had to free up space on my computer (sharing the same place for my film company). Would anyone mind sending me the TransX file? Lo siento. :uhh:

Just use the Orbiter ZIP archive for that?

Also you should keep the documentation, it is a few 100 KB of value. Or do it like me and copy every important documentation on your tablet for easier reading during a mission.

Do you have a laptop? If you do, you can run it next to your desktop computer. Begin Orbiter on your desktop. Then get the laptop going with an Orbiter tutorial video on flights to the Moon or to Mars! And watch it while you are doing your own flight. This is how I learned Trans X.
