Sounds good.

Make several modular probes and give them fancy names.

Have various support classes like signal relay, charge stations, camera cleaning, resque etc

Sell rent lease the vehicles to customers who get to pilot them in vr.

Create a simulator where one can explore some already explored areas with the probes projected in real time. Create a market for map chunks.

I think it will make one hell of a game.

Roberts Space Industries Legatus bundle costs $48,000 USD and you only get pixels.

If you can have your own exploration submarine without having to deal with all the boring logistcs yourself people will gladly pay many times that and hire other players to do ingame jobs like keeping the signal alive.

If you can build the mothership with investors and crowdsourcing then maintain it with subscription fees and insurance policies it would be hilarious even before anyone finds anything interesting.
