Dustbowl

The crater on … exhibits long, irregular marks imprinted into the relatively soft upper layers of the asteroid. Science Officer … has recovered some interesting unexpected wreckage from the edges of the depression; wheeled vehicles, seemingly personal transports rather than research craft.

The crew of the … speculate that the crater may once have been used for sport, with some alien species pitting their personal locomotion devices against each other in tests of mechanical strength or speed in near-zero-G.

While the crater in question was most likely the result of a regular meteorite impact, the complex patterns in the resulting depression originated at a later time.

Science Officer … argues that these surface-level patterns are not the result of an impact but a collision, one between asteroid … and some unspecified orbital installation or ship of alien make.

In the center of a particularly large crater on … lies a cluster of metal shapes, doubtlessly of alien origin.

Science Officer … is convinced that they are massive, planetoid-mountable propulsion devices, intended to push … from its orbit for purposes and destinations unknown. The … is on standby, its crew ready to begin disassembly and analysis of the alleged propulsion systems with the hopes of improving our own thruster technology.
