Here's a new, first-ever look at Mercury from an up-close NASA spacecraft. Mercury is about the size of our moon, with temperatures ranging from roughly 800 degrees Fahrenheit to minus-280 degrees Fahrenheit. It orbits the Sun every 88 days but revolves very slowly—only once every 58.6 days. So one Mercury "day" lasts almost as long as two Earth months. Because gravity is less powerful on Mercury, a 200-pound Earthling standing on its surface would weigh only 76 pounds...before being incinerated or turned into a freeze-dried block of human ice.

Crawford Long, the U.S. doctor who was the first physician to use ether on patients undergoing surgery, would have turned 169 yesterday. If you ever complain about the harsh world we live in, just read an account of what surgery was like in the days before modern anaesthesia.
