‘Hedgehog’ robot may someday hop, tumble, and flip to explore a comet or asteroid

A hopping cube may be the best way to explore a small asteroid or comet: ‘Hedgehog’ Robots Hop, Tumble in Microgravity Hopping, tumbling and flipping over are not typical maneuvers you would expect from a spacecraft exploring other worlds. Traditional Mars rovers, for example, roll around on wheels, and they can’t operate upside-down. But on … Continue reading ‘Hedgehog’ robot may someday hop, tumble, and flip to explore a comet or asteroid

Sci-Tech: Mach’s principle, James Woodward, and propellantless propulsion

Last January at the NASA Innovative Advanced Concepts Symposium, Gary Hudson, head of the  Space Studies Institute, outlined the experimental investigation that  James Woodward at California State University Fullerton has been doing for many years into the question of whether Mach’s principle leads to propellantless propulsion. (See Gary’s talk in this NIAC 2014 video.) Recently Charles Platt posted an interesting update on Woodward’s work :  Strange … Continue reading Sci-Tech: Mach’s principle, James Woodward, and propellantless propulsion

Sci-Tech: Suspended animation for medical apps and space travel

We don’t yet have self-aware robots or low cost transportation to orbit but we do have iPhones and Google search. The latter two are just as sci-fi as the former two technologies for someone who grew up in the 1960s. The future really is hard to predict.  Some tech that seemed almost in hand keeps getting pushed … Continue reading Sci-Tech: Suspended animation for medical apps and space travel

John G. Cramer on Space Drives

Professor John G Cramer, a theoretical physicist at the Univ. of Washington, has had a column for many years in the magazine Analog Science Fiction & Fact in which he writes about topics at the leading edge of science and beyond. His latest column is about two concepts for propellantless propulsion systems and some intriguing experimental results: Is It Space … Continue reading John G. Cramer on Space Drives
