I helped write a report [1] about the state of the Space Resources industry for 2019. This report should get you up to speed on the science, engineering, and law/policy going on in the field.
Our website specifically covers ISRU, including a monthly newsletter and sporadic articles (including one published this morning about minimizing lunar dust kick-up when landing vehicles on the Moon).
NASA Swamp Works does a lot of research on setting up a moon base, mining on the moon, etc.
They also sponsor the NASA Lunabotics Competition (formerly NASA Robotic Mining Competition), in which collegiate teams build robots to collect material in an environment very similar to the moon.
Philip Metzger is a great follow in Twitter. He was previously at Swamp Works before moving to an academic role. https://twitter.com/DrPhiltill?s=20
