Identifying Regions on Mars for Past Life Signs
Mars has been a frozen desert for billions of years. Any evidence of life near the surface will likely be fossilized and probably damaged, thus making it very difficult to recognize. If life ever evolved on Mars, there is a real possibility that the last surface ecosystems occupied land habitats, not aquatic ones. Those “last outposts” could contain the best-preserved evidence of past life on the planet.

A Martian Dustup
By studying and comparing how dust is lofted and transported on Earth and Mars, we can gain insight into how best to study this material, and understand how it can affect our lives.

Expose-R2 Photochemistry on the Space Station
After 18 months mounted externally on the International Space Station Zvezda module, the European Space Agency Expose-R2 Photochemistry on the Space Station (PSS) experiment was retrieved by cosmonauts during a February spacewalk. The PSS experiment investigated the evolution of organic compounds upon exposure to space radiation.

Moons of Saturn May Be Younger Than the Dinosaurs
New research suggests that some of Saturn’s icy moons, as well as its famous rings, might be modern adornments. Their dramatic birth may have taken place a mere hundred million years ago, more recent than the reign of many dinosaurs.
