NASA's Opportunity rover, the third robot wanderer who landed on Mars, changed our understanding of the Martian landscape, geology, atmosphere and history. On Wednesday, NASA announced its mission complete and officially ended the life of the Rover. The dear robot was circling the Martian surface for about 5,515 Earth days, just over 15 years.
At a press conference, NASA said Opportunity had not reacted to last effort on Tuesday to make contact. A planet surrounding a dust stormwith Opportunity on June 10, 2018, preventing the storage of solar panels. Since then, over 830 rescue commands have been sent to the Rover.
Tuesday night, despite the handing over of Billie Holidays and commands I'll see you on Mars via Deep Space Network, the rover could not be awakened.
"I learned this morning that we have not heard back," said Thomas Carchius, an associate administrator of NASA's Science Mission Directorate, at a press conference.
"That's why I stand here with a deep gratitude and gratitude [and] I declare that the mission of opportunity is complete, "he concluded.

The story of Opportunity is that of sustainability, discovery and miracle. This is a breaker of record, a testimony to the mastery of NASA engineers, scientists and executives who have been building, operating and piloting the router for more than 14 years. His last resting place lies on the western end of the Endeavor, in a trough that the science team called the Valley of Constancy.
The Rover started on 7 July 2003 and landed on Meridiani Planum on Mars on January 25, 2004. Its initial mission was to continue for a little over three months, but the robust rover continued to wander Martian soil for nearly 15 years. , traveling 28.06 miles (about 45 kilometers) – the farthest distance achieved by any unplanned robot.
This is the second of the double ruvers sent to the planet in 2003 as part of the Mars Exploration Rover (MER) mission. The first rider, Spirit, hit a sand trap in 2009. NASA officially announced that its mission was completed in 2011.
Opportunity made several remarkable discoveries on Mars, piercing the first meteorite found on another planet, revealing that once Meridiani Planum was immersed in water, studying over 100 craters and delivering countless stunning panoramas on the planet at about 34 million miles.
After landing in 2004, the golf cart-sized robot began its journey to the Endurance craft, spending six months exploring the rock foundation and sand dunes. The opportunity will continue to study about half a mile (730 meters) crater Victoria between 2006 and 2008, revealing how the water has entered and left the region billions of years ago.
In 2011, it reached Endeavor, a 13.7 mile crater with a 13.7 mile stroke after three years of travel. He found a bright mineral vein of gypsum. At that time, Steve Squires, mission chief investigator, said, "This tells the story that water runs through underground fractures in the rock." It also broke the image of the scandalous "dusty devils", whirlwinds that sometimes arise on the surface of Mars.
His journey was not without some scare. In 2005, Opportunity was buried in the dune, a fate that has crippled and ultimately claimed to be a robotic twin. On Earth, NASA has worked to mimic Martian soil before performing careful maneuvers for free. Roberto suffered his first dust storm in 2007, struggling with wheel problems and trying to work with a problem-robotic hand throughout his expedition.
Still, it seemed that nothing could break the fearless robotic explorer. On his 5th Martian Day, he celebrates with his first companions.
The opportunity will remain dormant in the Valley of Constancy, from time to time will be spied on by passing orbit – or perhaps in the distant future, pulled out and idolized as a pioneer, pointing the way for the first people to reach or even settle on Mars.
"It's because of the first missions," Opportunity, "that a day will come when our brave astronauts walk on the surface of Mars," said Bridental.
The robot has survived the NASA Curiosity Rover, which remains the only active racer on the surface of Mars. NASA will join itand , which will be commissioned in 2020.
NASA is 60 years old: The space agency has taken humanity away from each other and has plans to go further.
Take it to extremes: Mix mad situations – erupting volcanoes, nuclear crashes, 30-foot waves – with everyday technologies. Here's what's happening.
