"The product of implanted hydrogen and helium."-Michelle Thompson

Starts at 2:00.

This is a follow-up of Hayabusa2 sample return. The sample is being studied; what is seen? Turns out bubbles.

• A note for the slide at 5:00. Just so I can refer back to it as a good meme for 'space weathering'.
• Slide at 10:00 has a few reveals for me. I did not know one could measure solar wind exposure in terms of micro deposits.
• Slide at 19:00. I never saw the image she called attention to, the one on the right. Shadow of the spacecraft over the hole it made. That's actually a pretty monumental meme.
• Implications at 41:40.
