The nice thing about doing science on the moon is that it’s safe there. No matter how mad the experiment gets, there’s about two hundred and forty thousand miles between the two planetary bodies and it’s all hard vacuum and radiation. It couldn’t be any safer or more quarantined while still being within reasonable distance of radio communication back to home base. Even a ravenous biomass of iron-consuming fury would think twice about covering that kind of distance, if only due to the travel time giving Earth forces plenty of advance notice to nuke it into oblivion. If there was something like a stargate up there making transport to the home planet trivial, that would just be incredibly poor planning.
