I use Tetra Gun Grease. I don't know if it's rated for use on Venus or the moons of Saturn. It works fine for my needs. I've also used PJ1 Black Label chain lube too. It actually does quite well. Flows into place and stays put. For extended storage, Maxima Chain Wax is essentially Cosmolene with a few extra ingredients.
I wouldn't get to deep into the weeds on this grease thing.

Liberals are constantly telling us about the poor and oppressed in this country. With that in mind, why do they feel the need to keep importing poor people from other countries?
