Using the most powerful high-resolution camera ever sent to Mars, MRO produces stunning images that help scientists discern how geologic forces shaped the surface. The reduced pressure caused the engine thrust to be diminished by 2%, but MRO automatically compensated by extending the burn time by 33 seconds.[13]. MRO's Shallow Subsurface Radar (SHARAD) experiment is designed to probe the internal structure of the Martian polar ice caps. [42], The Mars Color Imager (MARCI) is a wide-angle, relatively low-resolution camera that views the surface of Mars in five visible and two ultraviolet bands. Additionally, MRO is the cornerstone of NASA's satellite NASA's Mars Reconnaissance Orbiter, known as MRO, is an orbiting spacecraft studying Mars' climate and geology since 2006. electromagnetic spectrum—basically, ranges of colors, many of which are other. Seasonally active frost-dust avalanches on a north polar scarp of Mars captured by HiRISE. geologic forces that shaped our planet, and how did they create the [33], The High Resolution Imaging Science Experiment (HiRISE) camera is a 0.5 m (1 ft 8 in) reflecting telescope, the largest ever carried on a deep space mission, and has a resolution of 1 microradian (μrad), or 0.3 m (1 ft 0 in) from an altitude of 300 km (190 mi). The system consists of a very large (3 m (9.8 ft)) antenna, which is used to transmit data through the Deep Space Network via X-band frequencies at 8 GHz, and it demonstrates the use of the Ka band at 32 GHz for higher data rates. The Ka downlink is the only remaining backup for this functionality, and since the Ka-band capability of one of the SDST transponders has already failed,[62] (and the other might have the same problem) JPL decided to halt all Ka-band demonstrations and hold the remaining capability in reserve. The cost to develop and operate MRO through the end of its prime mission in 2010 was US$716.6 million. at great detail to identify geologic processes that shaped it, from the This memory capacity is not actually that large considering the amount of data to be acquired; for example, a single image from the HiRISE camera can be as large as 28 Gb. The crater on the left is before ice disappeared. Its primary goals are to map the Martian surface with a high-resolution telescopic camera, at least partly to help select sites for future landing missions. In addition to protocol controlled inter-spacecraft data links of 1 kbit/s to 2 Mbit/s, Electra also provides Doppler data collection, open loop recording and a highly accurate timing service based on a 5e−13 USO.
