The interiors of these lava tubes will have stuff seen nowhere else in the solar system. They are millions, even hundreds of millions of years old, so evidence of processes that take that long will be everywhere inside. Picture stuff sublimating and crystallizing just a few atoms at a time, building up fantastic filigree.
It probably needs a probe modeled on an ostrich or kiwi to explore inside, moving about by hopping. You would not want anything that makes heat to be on the probe, or it would ruin things when it got close. Even bright light could destroy the best things.
