Good job [up]
Any chance for the Col 285 Sector UZ-O c6-10 one you can add in that the settlement is named "Orion's Folly" (it appears on the right panel as this when you get clos), it may not be important but it's useful for reference just in case, and well sometimes flavour text can give clues to links.

What makes me question a generation ship is that there only seems to be 4 crew members (when you read the story text). Like generation ships normally have lots of people (hence the name).
Doesn't totally rule it out of course, anything could have happened, they could be the last survivors.
Likely they were the "on duty" crew awoken early to land the ship - the rest of the colonists might still be in hibernation.
Oh and this quote from Wikipedia is interesting - "Later studies indicate that the top cruise velocity that can theoretically be achieved are a few percent of the
speed of light (0.08-0.1c).
[URL="https://en.wikipedia.org/wiki/Project_Orion_%28nuclear_propulsion%29#cite_note-Cosmos_by_Carl_Sagan-17"][17][/URL] An atomic (fission) Orion can achieve perhaps 9%-11% of the speed of light. A nuclear pulse drive starship powered by Fusion-
antimatter catalyzed nuclear pulse propulsion units would be similarly in the 10% range and pure
Matter-antimatter annihilation rockets would be theoretically capable of obtaining a velocity between 50% to 80% of the
speed of light. In each case saving fuel for slowing down halves the max. speed. The concept of using a
magnetic sail to decelerate the spacecraft as it approaches its destination has been discussed as an alternative to using propellant, this would allow the ship to travel near the maximum theoretical velocity "
I'd think chemical propulsion to get of the surface in the case of our "lost" base, before reverting to nuclear propulsion.
