From the publisher blurb:
You've left Earth behind you for the promise of a new world. And you are not turning back.
At the start of the Colonization era, humanity grapples with finding out the consequences of pumping 55 gigatons a year of carbon into the atmosphere and a global population in excess of 10 billion. Meanwhile, the precarious human presence in space numbers in the hundreds - initially in near Earth orbit (NEO) infrastructure projects but subsequently at temporary or permanent space colonies formed by crew or colonists on asteroids, moons and the other planets.
You've landed at one such potential colony, to prospect it for valuable ores and most precious of all – water! – which will allow you to build an extraterrestrial factory to extract raw stuffs such as isotopes and volatiles from the regolith, refine them into inks and 3D print complex technologies not available back on Earth. You'll assemble buildings for your colony, seed algae farms in your waste water and more complex biomes to grow neowoods and perishable goods. You'll want to automate as much as you can by designing and constructing robots to help you with repetitive tasks such as digging the enormous quantities of dirt you'll need for solar flare shielding and construction materials. And much of this you'll launch into space using mass drivers and freighters filled with spacecraft components bound for other markets.
(A)-Base (D)-Landing is a 257 page supplement for the Sixty Years In Space TTRPG and includes the Site Map and Robot designers to allow you to map uninhabited sites, travel across them and build complex bases on them.
