Icy caves, distant moons, hot air balloons and radio waves… In November we concluded our work on a three-year NASA-funded project to test different strategies to transmit data through 100s of meters (and someday kilometers!) of ice on Europa and Enceladus. We built and tested transponder “pucks” that used UHF (ultra high frequency) patch antennas and HF (high frequency) ferrite-core crossed loop antennas. We traveled to the Arctic and demonstrated through-ice transmission in an ice cave. Back in the States, we also demonstrated a novel end-fire dipole antenna by suspending it from a hot air balloon! When a cryobot descends into the vast ice shells on these moons, it will probably use a fiber optic tether to send data from the robot to a base station on the surface of the ice. But a backup means of sending data is needed in case that fiber fails. Data gathered in the PARTI Pucks (Puck-based data transmission using Adaptive Radio modems for Through-Ice communications) project support that different antennas may be adapted for use in different parts of Europa’s ice shell. #cuboulder #exploration University of Colorado Boulder

Smart tools and systems for exploring the frontier
关于我们
Stone Aerospace is a Texas-based company dedicated to the exploration and commercialization of the frontiers we know of and the discovery of the ones yet to come. We develop the tools needed to explore the frontier, to survive and work in it, to characterize it, and to exploit it. Our people are both seasoned expeditionary scientists and explorers -- who personally use the equipment we design in demanding environments -- and best-of-class engineers and coders. We are novel, lean, fast moving, and cutting-edge. We strive to change the way things are done, to cut red tape, and get reliable hardware into the field rapidly. Our business structure and extensive partnerships allow us to swiftly assemble extraordinary multi-disciplinary teams to tackle complex high-tech projects.
