A scaled-down version of the aerobot that could one day take to the Venusian skies successfully completed two Nevada test flights, marking a milestone for the project. The intense pressure, heat, and corrosive gases of Venus’ surface are enough to disable even the most robust spacecraft in a matter of hours. But a few dozen […]
