So I'm looking for a realistic manned Mars mission add-on. What I mean by realistic is that is relatively plausible with current technology. I've looked at OH and found [ame=http://orbithangar.com/searchid.php?ID=4792]this[/ame] and [ame=http://orbithangar.com/searchid.php?ID=3248]this[/ame] so I'm gonna try them.
Are there any other add-on like that?
