Mars crater life has people thinking space this week, as evidence of life on the planet may have recently been found by popular robot rover Curiosity. NASA’s planet explorer has discovered minute signs of microbial life within some of Mars’ craters, hinting that there may have been potential life on the Martian surface in past centuries, USA Today announces this Monday, Dec. 9, 2013.
Possible Mars crater life was hinted at by a shallow body of water found in the craters. The low waters carried a very low level of salinity, modest acidity amounts, and every required chemical that we know of that are needed to create organism life. With Earth as the obvious exception, Mars has been the most life-conducive place we’ve discovered so far in the entire solar system.
The robot rover’s big find of this little body of water may not seem like much, but the American Geophysical Union conference reported this afternoon that evidence of possible microbial life forms is a tremendous step in proving that there may have once been life in the now-lonely Martian surface.
"Is this the smoking gun that says there was life on Mars? Sadly, no," says NASA soil mineralogist Douglas Ming, who took part in the latest Mars crater life research. "Is this a smoking gun that this was a habitable environment? There's pretty good evidence for that in these craters. We have an environment [the body of water] that is very much … like on Earth."
There has always been trouble finding any proof whatsoever that there was Martian life, but this is certainly a step in the direction, another source from the space study event adds.
"I've always been an optimist that we will find it someday," says astrobiologist Clark Johnson of the University of Wisconsin-Madison, who was not involved with the study. "This is a wonderful step forward."
What is your response to the rover’s Mars crater life discovery? Do you agree life may have once existed on other planets, or may continue to do so now?
