was met five years of the arrival of the Mars Reconnaissance Orbiter . The March 10, 2006, and after seven months of travel, the six key drivers were put in place for nearly 27 minutes, just enough to speed be reduced enough to allow gravity to Mars permanently caught him ... were moments of great tension, because it was a delicate maneuver, and reached its peak when I pass behind the planet and communications were cut momentarily, but eventually all those involved were able to vent their joy: The Mars Reconnaissance Orbiter was already in orbit around Mars .
been 5 years since that day, half a decade that forever changed our understanding of the red planet, offering the possibility to see with a clarity never before dreamed of thanks to the HiRISE camera , The strongest ever sent to another planet ... at this time the MRO has sent almost 131 Terabaits of information (more than any other interplanetary missions together) to Earth, including 70,000 photographs of high quality, which gives an idea of \u200b\u200bthe tremendous work being done and what is irreplaceable in the current exploration of Mars.
How could it be otherwise so much data has respresented a breakthrough in our understanding of the red planet, especially to light that could be the evolution of Mars since its formation and the various "eras" which seems to have lived since past with clear signs of having been wet and warm up to this as cold and dry as we see today.
Thus, the observation of the oldest parts of the world, those showing a densely cratered terrain, allow to locate land that had been heavily altered by water, wetlands, areas that might have been suitable for life in pirmeros those times. It was also discovered clear evidence of extreme weather cycles, where water would be circulated in the form of gas, from the poles to low latitudes, which would have enabled device in the form of ice or snow, resulting in extensive layers of ice and rocks possibly necsitaron tens or hundreds of millions of years to form what looks like the ice ages that have occurred in Earth and in this case seems related to changes in the tilt of its axis of rotation.
also the MRO also taught us that the current Mars, although a dry and frozen world, not devoid of dynamism ... cycle CO2 , freezing and sublimating the rhythm of the stations, and the possible presence of liquid water occasionally, continues to change some parts of the planet, like avalanches and large dust storms. Frozen in reality, but not frozen in time.
not end here the achievements of the tube ... well, has raised a map of the mineral composition of 3 / 4 of the Martian surface (Compact Reconnaissance Spectrometer ), monitored the atmosphere (Mars Climate Sounder) and sounded the subsurface radar ( Shallow Radar), in an exploration of Mars without predecedentes.
" Each Martian year is unique, and additional coverage gives us a better opportunity to understand the nature of the changes in its atmosphere and surface. We've already learned that Mars is a planet more diverse and dynamic than we knew five years ago. continue to see new things, "said Rich Zurek, the scientific team of the Mars Reconnaissance Orbiter.
And, in the transitory golden age that we live in the exploration of Mars , many vehicles are on the planet working simultaniamente red, also had its role in supporting other missions ... well, followed the landing of the Phoenix Mars (in fact I get to photograph in full decline, in a historical image), monitored dust storms that could represent a threat to them as Spirit and Opportunity , and perform liaison functions between them and Earth. In view of the future is to examine potential sites suitable to be chosen for future rover landing Curiosity.
Five wonderful years for the exploration of Mars , and likely are far from over, as Phil explains Varghese, director of the project: "The is born with excellent health. After five years on Mars continues to have the ability to address scientific observations, monitor the Martian environment and liaise communications. " And so be it.
Some pictures are worth a thousand words ... a selection of images taken earlier this year.

August 12, 2005, the MRO begins his adventure with the aim to revolutionize our understanding of Mars. Six years later, that goal a reality. Prolific NASA Orbiter Reaches Five-Year Mark
