Attempts to explain water loss from Mars

Abstract:  The debate about whether or not Mars ever had life upon it centers on the issue of water.

Was there water on Mars?  If so, where has it gone?  One of the explanations for the water loss focuses on the idea that the solar wind is removing the water by acceleration ionospheric ions and removing them from Mars.  

Rosetta: Wild Bounce at comet Churyumov-Gerasimenko

Abstract:  Rosetta is the third cornerstone mission of the European Space Agency's (ESA) Horizon 2000 Programme.

Exploring the Inner Edge of the Habitable Zone in the Early Solar System

Abstract: 3-D models can help explore the possible roles of rotation, atmosphere and ocean dynamical transports, cloud feedbacks and sea ice-albedo feedbacks in determining the habitability of a range of planetary environments. Using recent modifications to the Goddard Institute for Space Studies (GISS) IPCC AR5 General Circulation Model (GCM) we have explored the Inner Edge of the habitable zone (HZ) of our Solar System.

Rise of the Machines: Mining the Kepler Data for Astrobiology

Kepler space telescopeAbstract: Since its launch in 2009, NASA's Kepler Mission has transformed our knowledge of exoplanetary system demographics. Kepler's primary mission goal-- to quantify the occurrence rate of habitable zone Earth-size planets around Sun-like stars-- has a clear connection to astrobiology.

A link between meteoritic organic compounds and the homochirality of life?

Abstract: Current theories suggest that portions of interstellar compounds should eventually be incorporated into the comets, "asteroids" and planets of new planetary systems. Astronomical observations point to processes such as the formation of comet and asteroid belts, familiar to our solar system, as likely occurring in many star systems. As with comets and asteroids, the formation of organic compounds around new-formed stars might be a common process.
