NASA Life on Mars - Joy Crisp
Is there life on Mars? It's a question asked time and time again. And NASA's Mars Curiosity Rover may be a step closer to answering the question. The rover has measured a tenfold spike in plumes of methane. They have been detected in a small area in the so called Gale Crater, that's the 154 kilometre wide crater Curiosity has been exploring. And it's the concentrated nature of the methane which has scientists wondering about the possibility of a life form being responsible.
