As the news feeds on Earth froth at the discovery of alien life, and the colonists frantically try to keep abreast of the groundbreaking work before them, you receive some long-expected good news.
At long last, half the vehicles from Laelaps rocket have returned to you. The other half have already been sent out to explore the surface and set up the beacons for the Talos satellite, which should arrive back soon enough.
The data from the vehicles' journey there and back is invaluable in mapping the surface of the moon. As an unexpected bonus, the engineers inform you that they were able to program the semi-autonomous vehicles to collect discarded parts of the rocket along the way, which can be retrofitted as building material. Enough at least for one extra colony room!
