Burst Point Revealed in this Backwards Video


What part of the balloon, the workhorse of John Powell’s JP Aerospace experiments in the upper regions at the edge of space, is the first to burst? Is it the top or the bottom where the balloon is connected to the tether and the experiment racks below it? I thought it was the nethers of the latex balloon, but this video changed my mind. Yet, does it always happen this way? Maybe JP can tell us. http://www.jpaerospace.com

Forgotten SR-71 Competitor: Project Hazel


Forgotten not by us! This project lost the bid for the US military’s high flying reconnaissance jet. The SR-71 won. Strange enough. The Hazel would probably have been faster and higher, but somehow inflated dirigible craft are considered not standard. So, just like the skin of the ISS, aluminum was the envelope of choice. I believe the fabric designs of Bigelow’s space habitat and the gossamer wings of JP Aerospace’s Ascender craft will show the way for rotational spaceships of similar design. To stay abreast of changes, start with The Space Trade Update and my next book on building ships in orbit. http://www.thespacetrade.com

A Santa Package of Strangely Sweet New Physics Theories, Facts, and Quips

From the Queen of Physics Facts and Quips, Sabine Hossenfelder, comes a delightful sleigh ride of news from an amazing corner of the universe, a place known to its inhabitants as Earth. This video is full of giggles and snickers from the peanut gallery of your active imagination as you follow the Grand Mistress of Science to the hidden caves of arcane understandings.

Natural Forces Are Best

At least where parachute deployment is concerned. Deploy it too early and the chute doesn’t open; deploy too late and the chute is ripped to shreds. So John lets natural forces determine the time for chute deployment. How? He put holes in the chute basket and as the craft descends into thicker air, the chute is forced out and opens gracefully, or at least adequately on time. – L Paul Turner http://www.thespacetrade.com
