サマリー
In this episode we will explore the bleeding edge of satellite and satellite constellation miniaturization. These awe inspiring craft commonly known as Chipsats, Wafersats, Sprites, Monarchs, Kicksats, Starchips, or even just “Smart Dust” are facilitating the rapid miniaturization of space craft following an exponential trajectory stipulated by Moore's Law, no doubt enabling new incredible possibilities and discoveries just around the corner. We talk about the unique physics and associated challenges that these low-mass vehicles face in space, how incredible engineering is overcoming them, and how the Breakthrough Starshot project will tackle the very difficult problem of sending a spacecraft interstellar to Proxima b. Our guest today is Professor Zachary Manchester, who studied physics and aerospace engineering at Cornell University earning his BS and PHD respectively. Zac undertook his Postdoc at Harvard and became Assistant Professor at Stanford University, and later at Carnegie Mellon University where he now heads the Robotic Exploration Lab. He received critical acclaim for his Kickstarter.com crowdfunded Kicksat project - deploying an armada of chipsats in LEO and has published together with Mason Peck and Avi Loeb and is member of the Breakthrough Starshot Research team, who are working on an interstellar spacecraft mission to Proxima-b.
