Ion Thrusters Propel NASA Into Future - SpaceDaily  Prometheus 1 would launch using conventional chemical rockets. But once in Earth's orbit, a nuclear electric propulsion system would propel it through space. Nuclear electric propulsion is over 10 times more efficient than chemical rockets and produces 20 times more power than the generators used on space probes such as Voyager and Cassini or solar-powered systems like Deep Space 1. "Solar power is efficient and lasting, but it cannot stop a spacecraft at targets in the outer solar system that are past Mars," Oleson said. "The only way we can do that in the outer solar system is with nuclear propulsion."   
New Telescope Begins Search For Life In Outer Space - SpaceDaily  The first telescope designed to search for alien life began operating this month from northern California. The state-of-the-art radio telescope, being operated by the SETI Institute, is still undergoing development and will be able to examine more stars in a year or two than Earth-bound scientists have been able to study in more than 45 years, the Washington Post reported Monday. "We could have a billion intelligent cultures with radio waves buzzing around them, but we haven't had the capability to detect them," said astronomer Michael M. Davis, who overseas the project.    

Physicists Control The Flip Of Electron Spin In New Study - SpaceDaily  Physicists in Europe, California and at Ohio University now have found a way to manipulate the spin of an electron with a jolt of voltage from a battery, according to research findings published in the recent issue of the journal Physical Review Letters. "Usually you have no control over this at all an electron flips its spin at some point, and you scratch your head and wonder why it happened. But in our experiment, we can choose how long this process takes." The scientists were able to manipulate how long it would take for the electron to flip its spin and emit a photon from one to 20 nanoseconds.
