All the High Places

From publisher blurb:

The inhabitants of the planet Aoru are deemed unready to join interstellar society, so their world has been declared off-limits, monitored by a network of satellites and a scientific research team. But fate seemingly has other ideas when one of the satellites crashes onto the slopes of the planet's highest mountain, threatening the locals with death and the offworlders with exposure. The PCs are on hand to help, but it may be their most problematic mission yet as they contend with the harsh mountain environment, a veil of official secrecy, and a relentless time limit.

All the High Places is a short adventure for 2D6 science fiction RPGs such as Cepheus Engine and the Original Science Fiction Roleplaying Game.
