While I am not a geologist (planetary scientist), I have always loved geology. I just checked and my index is 0.127. I live in Colorado so it is easy to take pictures of rocks. Here’s a fun one from Patagonia.

Looking forward to the launch of the Protoflight FireSat mission tonight on Transporter-13. FireSat is designed to detect and monitor wildfires to give first responders accurate, timely, and comprehensive information about fire conditions.

Robotic solar system exploration, night sky photography, exasperating earnestness. My day job is impersonating some of your favorite planets and spacecraft on social media for one of your favorite government agencies. Opinions here are my own.
