(( Our planet Mars has no appreciable magnetic field; at least, not a self-generating one. But enough to sustain wind. ))
Your unit's prime directive is overall the same as any android's. You are to find a suitable candidate for terraforming, settle there, build up an infrastructure, harness energy and develop resources, and if possible, seed it with life. There are likely hundreds or thousands of you scattered around the galaxy right now, perhaps produced by a wandering mothership and sent out to repeat the process, or made by one another exponentially. Your specific mission is hardly different—only your coordinates are unique, as you believe you are the only one of you currently in this sector of space...
...or, perhaps, just the only one who's managed to make it this far.
At any rate, the planet you're on seems to fulfill most basic criteria. It's further than ideal from its parent Class G star, meaning that in addition to life being more unlikely, it also receives less solar radiation. However, the presence (or history thereof) of high volcanism is a dead giveaway for the generous presence of iron, nickel, and other heavy base metals. Several times, now, you've recorded temperatures several degrees higher than expected, given the general lack of sunlight; this is almost certainly a combination of geothermal activity and greenhouse gases forming a thick black shell over the sky, locking in what heat does accumulate here.
Throughout the night, production continues apace. You currently lack a more sophisticated infrastructure, but it's enough to make several new mining drones. And with them all tasked to the same general mode—dig deeper—the mountain you've burrowed into becomes a constant strip of moving lights and the tumbling avalanche of dropped-off rock and rubble.
What you are lacking in, however, is energy. You hardly need to make solar panels—your ship came with several backups—but gaining any appreciable power even during daylight cycles is a slow and daunting slog. You're also quite a bit further up off the ground than ideal to reach far enough down to tap geothermal energy, and even then, you will need a source of water or an equivalent medium to actually utilize the heat.
