Aside from their frequent appearances on ancient frescoes, statuary and artwork, such fanciful creatures of mythology don't have a clear origin, although some have linked the mermaid to lonely sailors who glimpsed dugongs (also known as sea cows) in the distance and made a giant leap.
But a recent discovery in an Iranian salt mine, one scholar suggests, may shed light on the origins of a famous satyr of antiquity, one so well known that it merited a visit from the emperor himself. The satyr is a goat-man in Greek legend who dances and frolics, playing pipes and chasing nymphs all day, living in a woodsy version of the Playboy Mansion.
The asteroid, called 2007 NS2, was discovered by astronomers at the La Sagra Observatory in southern Spain on 16 July. Based on its brightness, it is estimated to be about 1 kilometre across.
Steve Squyres of Cornell University, the lead scientist for the Mars Exploration Rovers (MER) project, said that both Spirit and Opportunity are in "excellent shape" based on a radio transmission received this morning.
"Both came through the weekend beautifully," Squyres said in a telephone interview. "They were both power positive over the weekend, meaning they were generating more power than they were consuming."
The amount of sunlight penetrating the dust-choked martian atmosphere has increased slightly in recent days, and the batteries of both rovers are fully charged, said Michael Meyer, lead scientist for the Mars Explorations Program at NASA Headquarters in Washington, D.C.
Astronomers measure atmospheric opacity in units of "tau." The lower the tau value, the clearer the sky.
Introducing the BioSuit: a prototype spacesuit recently completed by scientists at the Massachusetts Institute of Technology.
When the white high-tech design is finalized in a few years, it will be the first new look for astronauts in more than four decades, replacing the lumpy, awkward 300-pound outfit with something worthy of a super hero.
"The current spacesuit dates back to Apollo," said Robert Cassanova, director of the NASA Institute for Advanced Concepts, which partially funded the work. "It's a gas-pressurized bag that provides the atmospheric pressure humans need to survive, but they're heavy and bulky." The Michelin-man-like outfit is also exhausting -- about 70 percent of the energy astronauts expend is spent wearing the suit.
