At the Lunar and Planetary Science Conference, Jennifer Scully discussed possible water-carved gullies in an unusual location: within craters on Vesta. Water-carved gullies on Mars I can accept; but on an airless lumpy body? I was intrigued.
Simon Kattenhorn and Louise Prockter may finally have found subduction zones on Europa, which would it the only other place in the solar system besides Earth that is known to have active plate tectonics.
It's that time of year again: my favorite annual space science meeting, the Lunar and Planetary Science Conference, takes place all next week in Houston, Texas. Get ready for reports on everything from Mercury to the Moon to Mars to Miranda!
Ted Stryk reports on the status of the New Horizons mission from the mission's latest Science Team Meeting. Updates include the status of the Kuiper Belt target search and the use of ALMA to refine Pluto's ephemeris.
It's time to reassess Europa exploration, past, present and future. The Destination Europa! session at AGU, inspired by the eponymous website and movement, didn't take exactly that message as its theme, but it's what I got from the presentations. What an ELECTRIFYING meeting this has been for Europa exploration!
A close look at two international planetary science poster presentations from the 2013 AGU Fall Meeting featuring sediment experiments to better understand Martian geomorphology and Juno's plans for exploring Jupiter's ring system.
Ellen Stofan, NASA's Chief Scientist, and John Grunsfeld, the head of the Science Mission Directorate and a Hubble repair astronaut, highlighted recent NASA science discoveries at the American Geophysical Union conference in San Francisco.
