Navy May Help NASA Build Nuclear Reactor for Jupiter Mission - Space.com  A NASA project to Jupiter and several of its moons may depend on the U.S. Navy to provide the nuclear know-how in building a reactor for deep space exploration. The Jupiter Icy Moons Orbiter (JIMO) program is a flagship mission under NASA’s Project Prometheus – a multi-pronged effort to develop near- and long-term nuclear electric power and propulsion technologies. JIMO would be powered by a compact nuclear reactor
Breakthroughs In Capacity, Power Consumption Set To Revolutionize Photonics - SpaceDaily  For years, organic electro-optic polymers have held the promise of vastly improving technologies such as communications, data processing and image displays. Now it appears scientists are on the verge of breakthroughs that will bring dramatic progress in materials, as well as the devices in which they are used. Simply put, electro-optic polymers are being used to make devices that take information that typically has been transmitted electronically and transfer it to optical systems that use light--- not just how much information can be sent at one time but also the power required to transmit the information.   

Was Mars Born Bone Dry - SpaceDaily  Left:  MARSIS's long antenna will fly over Mars, bouncing radio waves over a selected area and then receiving and analyzing the "echoes." Any near-surface liquid water should send a strong signal.  The MER rovers Spirit and Opportunity, now traveling on the surface of Mars, are exploring a geography drier than the driest desert on Earth. Despite the polar ice caps and suspected pockets of liquid water beneath the martian surface, the amount of water on Mars is but a teaspoon compared to the vast watery reserves of Earth. Why is Mars so dry? The inner planets of our solar system - Mars, Earth, Venus and Mercury - formed by the accumulation of small rocks and dust that swirled around the sun in its earliest years. If the Earth and Mars are made of the same stardust, they should have been born with about the same ratio of water. Many scientists think Mars once was very watery, but lost its oceans due to the low mass of the planet.
