What's up in planetary missions in 2014
Posted by Emily Lakdawalla on 2013/12/31 01:15 CST | 4 comments
With the New Year upon us, what can we look forward to in 2014? For me, the main event of 2014 is that ESA's Rosetta mission finally -- finally! -- catches up to the comet it has been chasing for a decade. We will lose LADEE, gain two Mars orbiters, and launch Hayabusa 2. The year begins with an amazing 24 spacecraft exploring or cruising toward various planetary destinations.

Mars' chemical history: Phyllosian, Theiikian, Siderikian, oh my

I'm returning to the deep dive into the literature that began with articles about lunar basins and then explored the geologic time scales of Earth, Moon, and Mars. Now it's time to catch up to the last decade of Mars research and learn what "phyllosian", "theiikian", and "siderikian" eras are.

Those sneaky scientists on Curiosity managed to catch a Phobos transit of the Sun with one set of cameras, and to watch its shadow darkening the surface with another. COOL!
