River relic spied by Mars Express
Mars may seem to be an alien world, but many of its features look eerily familiar—such as this ancient, dried-up river system that stretches out for nearly 700 kilometres across the surface, making it one of the longest valley networks on the planet.

Spikes of Methane on Mars May Be Proof of Life and Pointers to its Locations
Let’s get the obvious out of the way first … Spikes of Methane would make a great name for a band. However, it would have to play really well to produce the excitement that real spikes of methane are generating amongst the space exploration community over an announcement by NASA that its Curiosity rover has… Continue reading Spikes of Methane on Mars May Be Proof of Life and Pointers to its Locations
Something on Mars Is Producing Gas Usually Made by Living Things on Earth
