There is a one-time use [ame="http://www.orbithangar.com/searchid.php?ID=4427"]UCGO lander[/ame], but it has engines. I don't think parachutes work very well in Mars' thin atmosphere, though, and if you have anything delicate in the containers you probably shouldn't bounce them around too much.
For the hangars, [ame="http://www.orbithangar.com/searchid.php?ID=3692"]here[/ame] is a mesh for them, taken from WIN. They aren't UCGO compatible, but BJ produced a vessel container for OFMM that spawns whatever vessel you'd like on activation. I've included it in a zip file, as it isn't available on Orbithangar or anywhere outside this forum. Have fun.
P.S. The SVTU belongs to BJ, so do not use it in an addon without his permission. (I say this because it was originally just a POC and didn't include a license.)
