NASA's Galileo began the second phase of its Jupiter journey, swooping over the Jovian moon, Europa, at an altitude of only 124 miles. This was the first encounter of the Galileo Europa mission, which began formally on Dec. 8, following the end of Galileo's primary mission. The Galileo Europa mission will study Jupiter's icy satellite in detail in hopes of shedding more light on the intriguing prospect that liquid oceans may lie under Europa's ice crust. The Galileo Europa mission is designed to follow up on these discoveries and will include eight consecutive Europa flybys through February 1999, followed by four Callisto flybys and one or two Iow encounters in late 1999, provided the spacecraft remains healthy.

Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
