A bitcoin node is probably more feasible than sending a single ASIC up in the LEO (Low-Earth Orbit) just to hash and operate at a loss. One area of concern is maintenance. Interference from other objects and the radiation from the sun will surely lessen the life of the machine, rendering it useless in just a couple of months. There's simply no feasible defense in sending a miner on the outer space. Just imagine its components be removed due to high-speed orbit, or causing the miner to fall from whatever vessel it is, amonh many other reasons.
I think the OP has a lot of imagination without knowing the facts and the reality of things and maybe he does not even now that mining rigs need some maintenance and should be regularly checked. And if ever his insane idea would come to reality the cost of maintenance will be far greater from the profit that he will get from space mining because the one who will maintain it will need to ride a rocket ship to space in this method will definitely cost a lot of money and time.
