Northrop Grumman has been toying with the idea of sending an inflatable aircraft to Venus since at least 2013 (PDF). Now the company feels it's ready to turn its concept into a real vessel. According to SpaceNews, Northrop Grumman is planning to enter its Venus Atmospheric Maneuverable Platform (VAMP) aircraft into NASA's New Frontiers competition slated to begin on October 1st. The aerospace corp envisions VAMP as a large but light plane, with a 151-foot wingspan and the ability to cruise Venus' skies for up to a full year at an altitude of 34 to 43 miles. It will be able to carry between 44 and 440 pounds of of payload, particularly instruments to gather data from the planet's atmosphere.
