Ice islands on Mars and Pluto could reveal past climate change
Many of the craters of Mars and Pluto feature relatively small ice islands unattached to their polar ice caps. These ice islands could be records of past climate change on Mars and Pluto, and could also provide clues about the workings of Martian water and ice, according to a new study in AGU’s Journal of Geophysical Research: Planets.

New map reveals geology and history of Pluto’s moon Charon
What a difference a planetary flyby makes. Pluto’s moon Charon — once no more than a fuzzy blob of pixels beside a larger blob — now has its first geological map, published in AGU’s Journal of Geophysical Research: Planets.

Research bolsters case for a present-day subsurface ocean on Pluto
An updated thermal model for Pluto suggests that liquid water beneath the dwarf planet’s ice shell may not be frozen yet.

New findings from the New Horizons mission show Pluto is ‘really crazy’
Whether or not you believe Pluto should be called a planet, you should still be awed by the initial findings from the data the spacecraft New Horizons collected during its flyby of the dwarf planet last July. The seven science instruments aboard New Horizons gathered nearly 50 gigabits of data on the spacecraft’s digital recorders. Much of this data is still streaming back to Earth, but preliminary data and observations were published this week in the journal Science.

Students collecting space dust may help find distant planets
NASA’s fastest spacecraft collects dust like no other scientific instrument. Hurtling through space on its one-way trip toward Pluto, New Horizons is measuring space dust — a technique that could help astronomers find planets in other solar systems.
GeoSpace is a blog on Earth and space science, managed by AGU’s Public Information staff. The blog features posts by AGU writers and guest contributors on all sorts of relevant science topics, but with a focus on new research and geo and space sciences-related stories that are currently in the news.
