Scientists find methane in Mars meteorites
The researchers examined samples from six meteorites of volcanic rock that originated on Mars. The meteorites contain gases in the same proportion and with the same isotopic composition as the Martian atmosphere. All six samples also contained methane, which was measured by crushing the rocks and running the emerging gas through a mass spectrometer.

The German Aerospace Center is scheduled to launch its Eu:CROPIS research satellite into orbit in early 2017. Its purpose is to test a biological life-support system for future human space missions. The satellite's payload includes an ion analyzer. This compact device will automatically monitor all of the system's internal processes.

The Dawn orbiter initially traced the path of the equator before crossing the north and south poles of Ceres. Researchers have used the images acquired thus far with the Framing Camera on board the spacecraft and the first three-dimensional terrain models created from them to produce a virtual scenic flight over icy Ceres.

A close-up of Comet 67P/Churyumov-Gerasimenko by NASA's ultraviolet instrument surprised scientists by revealing that electrons close to the comet's surface - not photons from the Sun as had been believed - cause the rapid breakup of water and carbon dioxide molecules spewing from the surface.
