Dawn One is a solar-powered climate observatory, one of many to come and an outgrowth of a long career for John Langford, Electra Aero’s CEO, and collaborator with Professor James G. Anderson of Harvard University. A seeming callback to John Langford’s human-powered aircraft from his MIT days, Dawn One is a 90-foot span unmanned aircraft system (UAS) destined to fly at stratospheric altitudes (49.000 feet maximum) while observing data for quantitative forecasts of risks in the climate.  We see its first flight from the Manassas Regional Airport in Virginia on September 9.  The assistants in hot pink  and orange vests are Hokies, part of Virginia Tech University, and whose name is explained in a lengthy Wikipedia entry. The “solar-battery hybrid electric research aircraft” is part of the Stratospheric Airborne Climate Observatory System (SACOS) program.  The program will consist of “an ensemble of solar powered aircraft operating for months in the stratosphere,” each “ each “focused on critical climate observing missions …
