DescriptionMSL HeatShield.jpg	English: The finished heat shield for NASA's Mars Science Laboratory, with a diameter of 4.5 meters (14 feet, 9 inches), is the largest ever built for descending through the atmosphere of any planet. This image shows the heat shield and a spacecraft worker at Lockheed Martin Space Systems, Denver, which built and tested the heat shield. The heat shield and the spacecraft's backshell together form an encapsulating aeroshell that will protect the mission's rover, Curiosity, from the intense heat and friction that will be generated as the flight system descends through the Martian atmosphere. The aeroshell has a steering capability produced by ejecting ballast that offsets the center of mass prior to entry into the atmosphere. This offset creates lift as it interacts with the thin Martian atmosphere and allows roll control and autonomous steering through the use of thrusters. Русский: Тепловой щит Марсианской Научной Лаборатории (Mars Science Laboratory), разработанной в НАСА, в полном сборе достигает диаметра 4,5 метра. На 10.07.2009 являлся самым крупным из когда-либо построенных для спуска в атмосферу какой-либо планеты. На этом снимке: тепловой щит и проверяющий его рабочий компании Lockheed Martin Space Systems, расположенной в Денвере. Теплозащитный экран и кожух космического аппарата вместе образуют составную «аэрооболочку» (AeroShell), которая защищала спускаемый аппарат миссии «Кьюриосити» от сильного жара, возникающего из-за трения при проходе и спуске корабля сквозь атмосферу Марса. Аэрооболочка имеет рулевое управление, обеспечиваемое сбрасываемым балластом, который даёт смещение центра масс при входе в атмосферу. Это смещение при взаимодействии с атмосферой создаёт подъёмную силу, которая позволяет контролировать крен и автоматически рулить при помощи двигателей малой тяги.
