SWRA

And of course, the gigantic rocket to get it there

The empty tank worked, thanks! Of course I'm floating upside down, but good enough.

I am trying to figure out how to float on Laythe, my attempts are all sinking. My lander is a Probobodyne HCES, with three MK2-R parachutes, two 1x6 solar panels, a Z-400 battery, 2G antenna on top, and Barometer and Thermometer for science (I've already maxed out my science tree so kinda useless, but hey). I jettison the heat shield before landing to reduce weight. There's no airbags or anything available. Is there something I can add that will make it float? I'd post a picture but I can't figure out how to do that
