Ices, Oceans, and Fire: Tuesday morning: Spectroscopy

Ices, Oceans, and Fire: Conference overload
I am now back home from the icy satellites conference and still have a day and a half's worth of notes to digest. Hopefully I'll get to all of them this week. It was quite a dense three days to dive in to as my first conference since the arrival... More»

Ices, Oceans, and Fire: Monday afternoon: Posters

Uranus ring plane crossing tomorrow!
For the second time this year, Earth is crossing the ring plane of Uranus. I won't go in to much detail about this because I covered the Uranus ring plane crossings in detail in an April post. This crossing will take us back to the southern,... More»

Ices, Oceans, and Fire: Monday afternoon: New Horizons at Jupiter

Stars Above, Earth Below: Go to the Mountains
Tyler Nordgren has filed another update on his Stars Above, Earth Below journey from the road -- in fact, he handed me his blog entry and pictures on a memory stick in the foyer outside the room in which the Ices, Oceans, and Fire conference is... More»

Ices, Oceans, and Fire: Monday afternoon: Terrestrial analogs-ish
I felt a bit overwhelmed after the morning's theory-laden sessions, so it was a relief to meet Anahita and her grandma (along for the trip -- who wouldn't want to visit Boulder in August?) and go have some lunch in the patio of a sandwich shop on... More»
