caption_attribution_description: English: NASA's Curiosity rover and its parachute were spotted by NASA's Mars Reconnaissance Orbiter as Curiosity descended to the surface on 5 Aug 2012 PDT (6 Aug EDT). The High-Resolution Imaging Science Experiment (HiRISE) camera captured this image of Curiosity while the orbiter was listening to transmissions from the rover. Curiosity and its parachute are in the center of the white box; the inset image is a cutout of the rover, shown with reduced brightness to avoid saturation. The rover is descending toward the etched plains just north of the sand dunes that fringe "Mt. Sharp." From the perspective of the orbiter, the parachute and Curiosity are flying at an angle relative to the surface, so the landing site does not appear directly below the rover. The parachute appears fully inflated and performing perfectly. Details in the parachute, such as the band gap at the edges and the central hole, are clearly seen. The cords connecting the parachute to the back shell cannot be seen, although they were seen in the image of NASA's Phoenix lander descending, perhaps due to the difference in lighting angles. The bright spot on the back shell containing Curiosity might be a specular reflection off of a shiny area. Curiosity was released from the back shell sometime after this image was acquired. This view is one product from an observation made by HiRISE targeted to the expected location of Curiosity about one minute prior to landing. It was captured in HiRISE CCD RED1, near the eastern edge of the swath width (there is a RED0 at the very edge). This means that the rover was a bit further east or downrange than predicted. The image scale is 13.2 inches (33.6 centimeters) per pixel. Deutsch: Der Curiosity rover der NASA und der zur Landung verwendete Fallschirm, aufgenommen vom Mars Reconnaissance Orbiter bei der Landung am 6. August 2012 MESZ. Die High-Resolution Imaging Science Experiment (HiRISE)-Kamera nahm dieses Foto auf, während der Orbiter als Relaystation für Funksignale von Curiosity diente. Curiosity und der Fallschirm sind in der Mitte der weißen Box, das Ausschnitsbild zeigt den Rover und Fallschirm. Die Bildauflösung beträgt 13,2 Inch (33,6 Zentimeter) pro Pixel. Русский: Марсоход NASA Curiosity (русск.«Любознательность») и парашют были замечены Mars Reconnaissance Orbiter (русск.«Марсианский разведывательный спутник») во время спуска на поверхность 5 августа 2012 PDT (6 августа EDT). Камеры High-Resolution Imaging Science Experiment (HiRISE) сфотографировали спускаемый марсоход в высоком разрешении. Искусственный спутник Марса использовался для прослушивания сигналов от Ровера. Любознательность и его парашют в центре белого поля, увеличенная вырезка показана с пониженной яркостью, чтобы избежать перенасыщения. Вездеход спускается на равнины к северу от песчаных дюн с краю горы Эолида. С точки зрения спутника, парашют и Curiosity летят под углом к поверхности, так что место посадки марсохода не видно.
context_page_description: Mars atmospheric entry is the entry into the atmosphere of Mars. High velocity entry into Martian air creates a CO₂-N₂ plasma, as opposed to O₂-N₂ for Earth air. Mars entry is affected by the radiative effects of hot CO₂ gas and Martian dust suspended in the air. Flight regimes for entry, descent, and landing systems include aerocapture, hypersonic, supersonic, and subsonic.
