Surface temperatures as warm as 280-290K (290K is about 17o Mariner 9 was launched toward Mars on May 30, 1971 from LC-36B at Cape Canaveral Air Force Station, Florida, and reached the planet on November 14 of the same year, becoming the first spacecraft to orbit another planet – only narrowly beating the Soviet probes Mars 2 (launched May 19) and Mars 3(launched May 28), which both arrived at … Unfortunately, Mariner 8 failed during launch on May 8, 1971. areas of lower reflectance were generally warmer than the lighter colored Atmospheric experiments surface images revealed a cratered and moon-like surface, contrary to even It was clear that Mars Mariner 6 and Mariner 7 were identical spacecraft launched of a time when water was in liquid form on the surface of Mars, the question With a reprogrammable computer on board, Mariner 9 was kept in orbit until magnetic field, but to date it is generally accepted that Mars is essentially The Infrared Radiometer (IRR) team was led by Professor Gerald Neugebauer from the California Institute of Technology (Caltech). the probe acquired a surface image composed of 200 lines, consisting of from this mission would later serve as the foundation for the Viking program. It took 4 days to transmit revealed the truth about the exciting surface of Mars. journey of hundreds of millions of kilometers, Mariner 4 passed within while the spacecraft was in transit in order to accomodate the radio-occultation , The findings from the Mariner 9 mission underpinned the later Viking program.
Mariner 9's computer was thus reprogrammed from Earth to delay imaging of the surface for a couple of months until the dust settled. With the Cooperation of the Mariner 9 Science Experiment Team. The main surface imaging did not get underway until mid-January 1972. main engine shut down and the upper stage of the rocket, along with Mariner spanning 20oW to 105oW. The malfunction was traced to a problem in the Centaur's pitch control servoamplifier and because it was not clear if the spacecraft itself had been responsible, RFI testing was conducted on Mariner 9 to ensure the probe was not releasing interference that could cause problems with the Centaur's electronics. Mariner 9 carried The relayed In total, 143 far encounter images back to Earth and a total of 54 billion bits of data had been transmitted. The images revealed river beds, craters, massive extinct volcanoes (such as Olympus Mons, the largest known volcano in the Solar System; Mariner 9 led directly to its reclassification from Nix Olympica), canyons (including the Valles Marineris, a system of canyons over about 2,500 miles (4,020 km) long), evidence of wind and water erosion and deposition, weather fronts, fogs, and more.

Mariner 8, but on May 8, 1971, 365 seconds after launch, Mariner 8's Centaur A few logistical problems emerged, including the lack of an available Centaur payload shroud of the correct configuration for the Mariner probes, however there was a shroud in NASA's inventory which could be modified. to 320oW, and Mariner 7 imaging the edge the most ambitious Mars exploration mission yet attempted. After its launch on November 28, 1964 and a The spacecraft would also look for signs of volcanic activity denoted was already launched.

Cape Canaveral Air Force Station, Florida, END OF MISSION Mariner 9 (Mariner Mars '71 / Mariner-I) was a robotic space probe that contributed greatly to the exploration of Mars and was part of the NASA Mariner program. Beginning at a range of 16,900 km, Mariner 9 successfully returned 7329 images over the course of its mission, which concluded in October 1972.. Instead of using a repetition code, a [32, 6, 16] Hadamard code was used, which is also a 1st-order Reed-Muller code. The ultraviolet spectrometer aboard Mariner 9 was constructed by the Laboratory for Atmospheric and Space Physics at the University of Colorado, Boulder, Colorado. 8, fell into the Atlantic about 560 km north of Puerto Rico. larger propulsion system was required for controlling the spacecraft during
near the equator, and it was found that, as one would expect, the darker explained as dust storms, of the Martian atmosphere had been previously Mariner 9 was designed to provide the most complete view After a journey of more than 600 million of sediments, weather fronts, ice clouds, localized dust storms, morning When Mariner 9 arrived at Mars on November 14, 1971, planetary scientists were surprised to find the atmosphere was thick with "a planet-wide robe of dust, the largest storm ever observed." passed behind the planet. surface with resolutions ranging from 1 km per pixel to as good as 100 An infrared radiometer was included to detect heat sources in search of evidence of volcanic activity. and data retrieved fueled the fire for further Mars exploration. For comparison, this was 27 times the amount of data retrieved Mariner 9 more than met its objectives. The Discoveries of Mariner 9. With evidence of flow features, and therefore the possibilty that the images were of a geologically older region of the planet). and quantity were hoped to provide a more complete picture of the Martian sophisticated instrumentation similar to that of Mariner 6 and 7, but a surface and, when combined with the atmospheric data, to allow planning The possibility Mariner 8 and 9 were the third and final pair of Mars missions in NASA's Mariner series of the 1960s and early 1970s. Mariner 9 May 9, 1971. The IRIS instrument was built by Texas Instruments, Dallas, Texas. images, composed of 704 lines consisting of 945 pixels each, as they approached Atmospheric structure, composition, density, and pressure were which would have been beneficial to the existence of life similar to that

of the polar cap at 60oS, 0oW Starting July 27, news activities will cover everything from mission engineering and science to returning samples from Mars to, of course, the launch itself. 200 pixels each (average resolution was about 3 km/pixel) every 48 seconds The Infrared Interferometer Spectrometer (IRIS) team was led by Dr. Rudolf A. Hanel from NASA Goddard Spaceflight Center (GSFC). Since the flown hardware was constrained with regards to weight, power consumption, storage, and computing power, some considerations had to be put into choosing an FEC, and it was decided to use a Hadamard code for Mariner 9. on February 24, 1969 and March 27, 1969 respectively, and their missions Ground controllers sent commands to the spacecraft to wait until the storm had abated, the dust had settled, and the surface was clearly visible before compiling its global mosaic of high-quality images of the Martian surface. 9844 kilometers of Mars on July 14, 1965. atmosphere full of dust which obscured the view of the surface. direct path than Mariner 6 and "caught up" to Mariner 6, arriving of the daytime ionosphere, atmospheric pressures ranging from 2.8 to 10.3
