When will we know if Mars has life?

The groundbreaking discovery by NASA of water on Mars is exciting one for sure — but when will we know whether or not there is life on the Red Planet?
Give it seven years, argues a recent Examiner.com report, which points to the fact that there are two missions to Mars between now and 2022.
While we do not lack for orbiters and probes both above and on the surface of Mars, they haven’t been able to turn up any sign of life, but they are not necessarily suited to doing so anyway.

The finding that not only there was water in Mars’ past, but today there is season flowing water has raised some excitement in the scientific community that maybe, perhaps, some type of microbial life exists on the planet that has found a way to survive the harsh climate and environment.
But there’s only one way to know for sure: get equipment down there that is capable of poking around in these spots for life. Culled from Morning Ticker
