• Interplanetary Transport Network – “The Interplanetary Transport Network (ITN)[1] is a collection of gravitationally determined pathways through the solar system that require very little energy for an object to follow. The ITN makes particular use of Lagrange points as locations where trajectories through space are redirected using little or no energy. These points have the peculiar property of allowing objects to orbit around them, despite the absence of any material object therein.“
• MSNBC: Science Thrives in Virtual Worlds – “Does the virtual-reality world known as Second Life have anything to offer for real-world scientists? Absolutely — and a trailblazing researcher says the payoffs are sure to increase when the Internet goes 3-D.“
