\n\t<\/a><\/p><\/div>\nSince the model isn\u2019t itself launching to the Moon, Firefly\u2019s recent Environmental Test Laboratory visit didn\u2019t include several types of trials that are generally completed only for flight hardware. A launchpad-bound spacecraft would undergo electromagnetic testing to ensure that signals from its electronic parts don\u2019t interfere with one another. And, in what is probably the most well-known environmental test, flight-bound hardware is baked or chilled at extreme temperatures in a thermal vacuum chamber from which all the air is sucked out. The multiple thermal vacuum chamber facilities at JPL include two large historic \u201cspace simulators\u201d built within NASA\u2019s first few years of existence: a chamber that\u2019s 10 feet in diameter<\/a> and another that\u2019s 25 feet across<\/a>.\u00a0<\/p>\n
