At 2pm EST today NASA will issue a press briefing during which it intends to announce significant findings about Mars. These findings come as a result of the ongoing success of its two rovers, Spirit and Opportunity. The word on the street is that the significant finding will be about evidence of past water on Mars. What would be really exciting would be some evidence of current water, realistically not as the freely flowing sort we know and love here on Earth, but perhaps as very salty brines intermingled with the Martian soil. However, where there’s water there’s a chance for life. Perhaps ‘significant’ could even mean… no, it couldn’t… could it?
