DARPA's 'Wasp' May Carry Powerful Sting  - BBC  the small, lightweight, hand-launched "Wasp" may be the Marine's new best friend when it comes to performing reconnaissance missions. The Wasp is a MAV—a micro-air vehicle—that weighs approximately 200 grams depending on its configuration. This tiny terror runs on two small Kokam Lithium Polymer "spar" batteries inserted in the carbon-fiber leading edge of each Kevlar wing which not only power the electric propulsion system, but also provide structural support for the wing. The Wasp carries forward- and side-looking fixed-focus color daylight cameras. The images from these cameras are relayed back to a ground control unit along with global positioning system coordinates.  
NASA To Test New 20-Meter Solar Sail - Science Daily  NASA engineers and their industry partners are preparing to test two 20-meter (66-feet) long solar sail propulsion system designs - a critical milestone in development of a unique propulsion technology using the Sun's energy that could lead to future deep space missions. The technology bounces a stream of solar energy particles, called photons, off giant, reflective sails made of lightweight material 40-to-100 times thinner than a piece of writing paper. These are just three of a number of efforts undertaken by NASA Centers, industry and academia to develop solar sail technology.
