Thanks to a surface covered in liquid water, Jupiter's moon Europa serves as the prime suspect for bodies in our solar system harboring extraterrestrial life. For the most part though, speculation has assumed the life on Europa would be microscopic, similar to the chemical and rock-eating microbes found atop undersea volcanic vents on Earth. However, a new study estimates the level of oxygen in Europa's seas may be high enough to support fish-sized life. Hello, alien sushi.

Not to be outdone by GM's Chevy Volt hoopla last week, Chrysler today revealed three prototypes from its own electric-car program earlier today on CNBC. Who knew Chrysler had an electric-car program? Practically no one. But the company calls it ENVI, pronounced "envy," and the first consumer product from the program could appear as early as 2010.

A radar device aboard ESA's Mars Express orbiter has allowed scientists to peek beneath the surface from afar, and the success with this research is now prompting them to think up other spots in the solar system that would be ideal for this sort of examination.

NASA hopes to someday use a robot like Bill Stone's DepthX to explore Europa, a frozen moon of Jupiter and one of the most probably places in our solar system to support life.

In July, the space shuttle Discovery is slated to deliver two tons of hardware and supplies to the partially built International Space Station. This mission is paid for. As for the 16 more needed to finish assembly, as mandated by President George W. Bush two years ago in his Vision for Space Exploration policy, NASA is short by as much as $5 billion.
