					<description><![CDATA[At present, the evidence suggests that life may have existed in the past on Mars, or not. However, the scientific consensus is that we assume life never arose on Mars, and will continue to do so until evidence pops out and bites us in the mass spectrometer. There is no evidence of life on Mars &#8230; <a href="https://gregladen.com/blog/2018/01/07/evidence-life-mars/" class="more-link">Continue reading <span class="screen-reader-text">Is There Evidence of Life On Mars?</span> <span class="meta-nav">&#8594;</span></a>]]></description>

It is being reported that this jelly-donut size rock appeared out of nowhere on the Martian surface between photographs. There are several possible explanations for this. 1) It grew there. 2) It was ejected from a steam vent &#8230; <a href="https://gregladen.com/blog/2014/01/21/go-home-mars-rock-youre-drunk-interplanetary-rock-makes-selfie/" class="more-link">Continue reading <span class="screen-reader-text">Go Home Mars Rock, You&#039;re Drunk!

The NASA Curiosity Mars Rover has discovered something interesting and rather enigmatic.
