From publisher blurb:
asteroid base / research station
This chapter of the 0hr Sci-Fi Settings product line presents two pairs of digital poster images and supporting documents that present an asteroid base in deep space. The maps are at 1 inch = 5 feet scale and have a 1-inch grid built in – perfect for Starfinder and other science fiction RPGs.
Lochlyn IX is a combination research outpost, medical facility, and defense platform with both civilian and military duties. The habitable areas of the station are divided into sections connected by a transit tube system using what are basically spherical elevators. Due to the rock's rotation "down" is always away from the core (out into space) and the station is at zero G along the axis of rotation. In effect, the buildings along the equatorial transit ring feel like they are hanging off the bottom of the asteroid rather than standing on its surface. But taking advantage of the low G along the axis of rotation are a large rectangular hangar at one pole and an octagonal cargo bay on the other.
