Two sizes of the giant Nexus plan by Convair. This was being drawn up while Saturn was still a thing, and while people were seriously looking at imminent moon bases. It's a mostly re-usable single stage to orbit booster, that then returns and tries landing using retro rockets to decelerate and break water tension on the ocean. There's secondary stages as well, with 1960's optimistic plans had been for open cycle gas core nuclear thermal rockets (adjusted for what we now know, but we still couldn't build one that would be stable).

Removed the incomplete Realism Overhaul config as is was causing issues (esp the part where I forgot the "NEEDS" tag, so it was double scaling the Nexus 2 plug engine). No other changes.

Update for KSP 1.2
Tweaks to colliders on decouplers to make them function with less explosions. Added a probe antenna to the heat shield.
I made the high efficiency GCR a dual mode using either active Lqd He cooling or Lqd H regenerative cooling (leads to more thrust, less ISP). There's the beginning of a Realism Overhaul config, but I wouldn't trust it just yet.
Killed off the reflective shader. This update is a bit untidy. Over the last few months I've messed around with various parts, and juggled Unity versions. As such, there's some extra 10MB of baggage that's probably useless. I'll be reviewing all the parts, and rebalancing for the next update.
