| (CNN) "Sheepbed" such as this on the surface of Mars has veins of deposited sediments that suggest the former presence of water. |
Last week, NASA definitively stated that Mars could have once been the home of microbial life. This assessment was made after Curiosity drilled into a rock and identified sulfur, nitrogen, hydrogen, oxygen, phosphorus and carbon. All of these elements are considered the fundamental ingredients for life as we know it. Additionally, this sample was composed of more than 20% smectite, a clay formed in the presence of water.
Today, the Curiosity rover has discovered even more substantial evidence of liquid water formerly existing on Mars. Melissa Rice of CalTech stated, "With Mastcam, we see elevated hydration signals in the narrow veins that cut many of the rocks in this area.These bright veins contain hydrated minerals that are different from the clay minerals in the surrounding rock matrix."
The Curiosity rover is currently located in Yellowknife bay, 7 months into its 2-year journey that cost $2.5 billion.The rover has been experiencing technical setbacks lately. A software error involving file formatting was enough to put the rover out of commission for this past weekend. The error re-occurred today, and may impede most of the rover's operations this week.
What's your reaction to possibility (and increasing likelihood) of both water and microbial life on Mars? Would you expect a public major reaction if NASA was indeed able to definitely prove the existence of either o these on Mars? Also, feel free to comment on the $2.5 billion price tag that this exploration has entailed.
In short: NASA finds evidence of water and states that Mars may have once been an ideal location for microbial life forms. Thoughts?
