Had no time to work on Polaris
or anything else last night and probably won't tonight either. Here's the short description on the lander module:
The access hatch is on the back side of the lander. It pops inward and rotates upward, similar to the way an aircraft boarding hatch works. On the ground, a ramp below the hatch also drops down to ground level. The outline of the ramp is visible in the more recent renderings.
I thought about the C57-D landing strut ladder approach, but I just didn't think the lander or the struts were big enough to be practical.
I'll get some sketches online as soon as I finish off the last couple of greebles on Polaris,
maybe tomorrow night.
