Flight Question Hohmann Transfer Callisto to Europa Launch Window

Clavius0712 · Apr 25, 2009

Hi,

I'm trying to create a scenario in which you perform a Hohmann transfer from Callisto to Europa (Ref: Jupiter). I'm using IMFD because I can never figure out how to use TransX. How do I work out the launch window such that when I arrive at Europa's orbit the moon is actually there?

Post your starting scenario and I would happily make an .avi video of setting up TransX for the trip.

Coo! Here you go. Thanks for this. If you can't use the text pasted below, let me know how I can send you the file. I tried uploading to Mediafire but the site must be down at the moment as no joy. N.B. The forum has changed a colon followed by a P in the ships section to

so just edit it back. [EDIT] Oh, and I forgot to mention I'm using the XR2 Ravenstar ship addon and the IMFD addon. I hope this isn't a problem for you.

I took the liberty of using a deltaglider since I didn't have an XR1. But the navigation is exactly the same so it shouldn't make any difference.
Hope you don't mind 14 minutes of avi for 31 megs.

let me know if the file doesn't download ok.

Great vid!

I gave it a go and it helped a lot. Thanks very much.

By the way, the idea behind the scenario was an article I read online about how Callisto was supposed to be the ideal place for a base in the Jovian system due to it being geologically stable and in a relatively radiaton-free region around Jupiter. It's also huge (40% bigger than Luna).

The scenario postulated Callisto being used as a base for exploration of the Jovian system - with Europa being a prime destination due to the possibility of a huge ocean beneath the ice in which life might be supported by hydrothermal vents.

Thanks once again.

It goes the other way, but you can see how to use IMFD to do such a Hohmann transfer...

Orbiter 2024 has been released!
