NASA : NASA's Mars Odyssey spacecraft .- El veterano de la NASA nave espacial se acerca la vuelta 60000a alrededor de Marte, pero no los Pit Stops

Hola amigos: A VUELO DE UN QUINDE EL BLOG., la Agencia Espacial NASA, nos hace llegar la información que su veterana nave espacial: NASA's Mars Odyssey orbiter, ha dado 60,000 vueltas alrededor de Marte.Este suceso lo cumplió el 23 de junio del 2015.

El nombre de la novela éxito de ventas "2001: Una odisea del espacio" de Arthur C. Clarke, NASA's Mars Odyssey orbiter;   comenzó a orbitar Marte hace casi 14 años, el 23 de octubre de 2001. El 15 de diciembre de 2010, se convirtió en la nave espacial más larga de funcionamiento nunca envió a Marte, y sigue manteniendo ese registro hoy.

NASA's Mars Odyssey spacecraft will reach a major milestone June 23, when it completes its 60,000th orbit since arriving at the Red Planet in 2001.

Named after the bestselling novel “2001: A Space Odyssey” by Arthur C. Clarke, Odyssey began orbiting Mars almost 14 years ago, on Oct. 23, 2001. On Dec. 15, 2010, it became the longest-operating spacecraft ever sent to Mars, and continues to hold that record today.

Odyssey, which discovered widespread water ice just beneath the surface of the Red Planet, is still going strong today, serving as a key communications relay for NASA's Mars rovers and making continued contributions to planetary science.

“This orbital milestone is an opportunity to celebrate Odyssey’s many achievements,” said Jim Green, NASA’s director of Planetary Science. “Odyssey will continue to help lay a foundation for the first humans to Mars in the 2030s through NASA’s Journey to Mars initiative.” 

Odyssey’s orbital milestone translates into about 888 million miles (1.43 billion kilometers) traversed by the spacecraft. In addition to the 286 million miles (460 million kilometers) covered on its trip from Earth to Mars, the spacecraft is a high-mileage vehicle like no other, but remains in fine condition.

"The spacecraft is in good health, with all subsystems functional and with enough propellant for about 10 more years," said David Lehman, project manager for the Mars Odyssey at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California.

Odyssey's major discoveries began in the early months of its two-year primary mission, with gamma-ray and neutron measurements that indicated plentiful water ice just beneath the surface at high latitudes on Mars. The spacecraft's unexpectedly long service has enabled achievements such as completion of the highest-resolution global map of Mars and observation of seasonal and year-to-year changes, such as freezing and thawing of carbon dioxide.

Through its many accomplishments, the spacecraft also has aided NASA’s preparations for human missions to Mars by monitoring radiation in the environment around the planet via the Mars Radiation Environment Experiment, developed at NASA’s Johnson Space Center in Houston.

Odyssey currently is completing an adjustment to an orbit that will position it to pass over Martian terrain lit by early-morning sunlight rather than afternoon light. In its current orbit, the spacecraft always flies near each pole and along what is called the terminator. The terminator is a moving “line” that encircles Mars and passes through any point on the planet’s surface at sunrise and again at sunset, separating the portion of Mars lit by the sun from the portion experiencing darkness, dividing day and night. The position of this line varies by time of day and time of year.

"Upcoming observations will focus on what is happening in the Martian atmosphere in the morning, such as clouds, hazes and fogs, and on frosts on the surface that burn off by later in the day," said Jeffrey Plaut, Odyssey project scientist at JPL.

The planned drift to a morning-daylight orbit began in 2012, was accelerated in 2014, and will be completed with a maneuver in November to lock in the orbit timing so that each pass over the equator occurs at the same time of day.

"We have performed many orbit maneuvers over the long life of this mission, and we will use that experience conducting the one to halt the drift," said Steve Sanders, Odyssey spacecraft engineer at Lockheed Martin Space Systems in Denver.  

To date, Odyssey's Thermal Emission Imaging System (THEMIS) has yielded 208,240 images in visible-light wavelengths and 188,760 in thermal infrared wavelengths. THEMIS images are the basis for detailed global maps and identification of some surface materials, such as chloride salt deposits and silica-rich terrain. The infrared imaging also indicates how quickly regions of the surface cool at night or warm in sunlight, telling researchers how dusty or rocky the ground is.

Odyssey's three-instrument Gamma Ray Spectrometer (GRS) suite detected significant amount of hydrogen on the planet -- interpreted as water ice hidden beneath the surface. This discovery prompted NASA to send its Phoenix Mars Lander to an arctic plain on Mars in 2008, where it examined the water ice detected by Odyssey. The spectrometer suite also mapped global distribution of key chemical elements, such as iron and potassium. The University of Arizona, Tucson, headed its development. Two GRS instruments are still active: the high-energy neutron detector from the Russian Space Research Institute and the neutron spectrometer from Los Alamos National Laboratories in New Mexico.

As a communications relay for NASA's Mars rovers, Odyssey has transmitted to Earth more than 90 percent of the data received from the Opportunity rover. Future plans for Odyssey include relay duty for NASA and European Space Agency landers arriving on Mars in 2016.

Odyssey launched on April 7, 2001 from Cape Canaveral Air Force Station, Florida. JPL manages the Mars Odyssey Project for NASA's Science Mission Directorate in Washington. Lockheed Martin built the spacecraft and collaborates with JPL in mission operations. Arizona State University, Tempe, provided and operates THEMIS.
