Conditions were so bad in early August that just before the launch of the Mars-bound Phoenix spacecraft, rover scientist Mark Lemmon feared the demise of the Opportunity rover.
"There was one sol [Martian day] when there was real uncertainty we'd hear from Opportunity," said Lemmon, a planetary scientist at Texas A&M University. He added that the plucky robotic explorer almost entered a power-saving mode that would have been dangerous "uncharted territory" for the rover team.
Still, Lemmon thinks the Mars rovers will persevere through the dusty conditions.
"Mars could throw worse storms at us, but for this season I think we have seen the worst," he told SPACE.com in an e-mail. "We got a good demonstration that Mars could kill them.""

Albert Einstein won the Nobel Prize for Physics in 1921
According to Einstein's special theory of relativity, it would require an infinite amount of energy to propel an object at more than 186,000 miles per second.
However, Dr Gunter Nimtz and Dr Alfons Stahlhofen, of the University of Koblenz, say they may have breached a key tenet of that theory

They recommend using IE, Opera or IE tab. From the site: Demographics have shown that not only are FireFox users a somewhat small percentage of the internet, they actually are even smaller in terms of online spending, therefore blocking FireFox seems to have only minimal financial drawbacks, whereas ending resource theft has tremendous financial rewards for honest, hard-working website owners and developers.

If they believe you look like you might be thinking of causing harm, you can be taken aside for further questioning. Welcome these new overseers: 'Behavior Detection Officers.' Their potentially life-changing decisions will be based on the pseudoscience of 'micro-expressions.'"
