The European Space Agency has selected Oxia Planum as the landing sight for the first European Mars rover, due to be sent on its way to the red planet in 2018.

The ESA's Rosetta probe has confirmed the presence of molecular oxygen in the cloud of gas surrounding the nucleus of comet 67P. This marks the first time that molecular oxygen has been confirmed in the gas surrounding a comet.

Scientists involved in the program are calling it the most surprising discovery to date.
