From the description:

This video clip shows HVO geologist Tim Orr sampling lava from an active pāhoehoe breakout on the episode 61g lava flow. The chemistry of these lava samples provides information on the magma plumbing system. Sampling has been a regular part of monitoring Kīlauea Volcano's ongoing Pu‘u‘ō‘ō eruption.

Today I learned that this is what that looks like. Very impressive.
