Geological probe

Used to survey a planet. The probe has a very low resource cost, so it can be manufactured even in the first stage of colonization. The probe blueprint is given to the colonist from the start.
With a probe you can "upgrade" any unoccupied point on the planet. On the first launch the probe goes down to the middle layer and analyzes the rock. A second probe at the same point surveys the planet's deep layer. Probes are single-use devices and are lost in the rock forever, so each survey requires a new probe.
