Mars


Our knowledge of Mars, past and present

For 20 years, the American astronomer Percival Lowell had one abiding passion--the planet Mars. He studied it as no other earthling ever had, and although he has been dead for nearly a half century, much of our present knowledge of the "red planet" comes from his findings. His observations formed the basis for his books: Mars, then Mars and Its Canals, Mars as the Abode of Life, The Evolution of Worlds, The Solar System, and The Genesis of the Planet. "Conditions may exist there under which our wildest fancies may be commonplace facts," he wrote.

Now, we have THEMIS (Thermal Emission Imaging System) orbiting the red planet. http://themis.asu.edu

The Thermal Emission Imaging System (THEMIS) is an instrument on board the Mars Odyssey spacecraft. It combines a 5-wavelength visual imaging system with a 9-wavelength infrared imaging system. Mars Odyssey launched from Kennedy Space Center on April 7, 2001 and arrived at Mars on October 24, 2001. It spent the next several months achieving a circular mapping orbit by aerobraking (dipping into the atmosphere to slow and shrink the orbit). Aerobraking concluded in early February 2002, and primary mapping operations began a few weeks later. The spacecraft is in a 2-hour orbit around Mars. As of 2015, it had completed 60,000 orbits of the planet Mars.
