NASA's Opportunity rover, the third robotic wanderer arriving on Mars, has changed our understanding of the landscape, geology, atmosphere and history of Martian. On Wednesday, NASA announced its mission to be complete and with it, the life of the rover was officially finished. The powerful robot travels over Martian over 5,51
At a press conference, NASA said Opportunity did not respond to a last Tuesday's effort to establish contact. A planet-encircling dust stormat Opportunity on June 10, 2018, preventing its solar panels from storing power. Since then, more than 830 rescue orders have been named in the rover.
On Tuesday night, despite sending commands and Billie Holiday I'll see you Head to Mars through the Deep Space Network, the rover will not arouse.
"I have learned this morning that we have not heard" said Thomas Zurbuchen, NASA's Scientific Affairs Mission overseer, during a press conference.
"Therefore I stand here with deep appreciation and gratitude [and] I declare that the mission opportunity is complete," he concluded.
NASA Administrator Jim Bridenstine shared his thoughts on Twitter,.
The story of opportunity is one of stability, discovery and admiration. It is a record-breaker, a testament to the courage of engineers, scientists and NASA leaders who have built, worked on and piloted the rover for over 14 years. The final resting spot is located on the west side of the Endeavor crater, in a ditch of science team called Perseverance Valley.
The rover was launched on July 7, 2003, and reached the Meridiani Planum on Mars on January 25, 2004. Its original mission was intended to last more than three months, but the hard rover continued to roam the Martian soil nearly 15 years, traveling 28.06 miles (around 45 kilometers) – the farthest distance that any super-planet robot can achieve.
This is the second of twin rovers sent to the planet in 2003 as part of the Mars Exploration Rover (MER) mission. The first rover, the Spirit, was stuck on a sand sand in 2009. NASA officially announced its mission which was completed in 2011.
Opportunity made some discoveries of Mars's signs, terrifying at first meteorite found on another planet, showing that the Meridiani Planum was once sunk, studying more than 100 impact craters and delivering countless stunning panoramas of a planet nearly 34 million miles away.
After landing in 2004, a golf-sized robot journey began at the Endurance crater, spending six months performing a wide-ranging bedrock investigation and sand dunes. The opportunity will continue to study Victoria's nearly half-mile (730 meters) estuary between 2006 and 2008, showing how water enters and leaves the region a billion years ago.
In 2011, it reached Endeavor, a bamboo impact of 13.7 miles wide, after three years of travel. It discovered a clear mineral vein of gypsum. At that time, Steve Squyres, a chief missionary investigator, said, "It tells a story of folly that the water flows beneath the rocks beneath the ground." It also gets an image of the humiliating "demons of the dust," hurricanes that occasionally appear over the Martian.
Its journey is not without scares. In 2005, Opportunity was acquired in a dune – a fortune with lumps and ultimately claimed its robotic twin. On Earth, NASA worked to reproduce Martian soil before performing careful maneuvers to release Opportunity. The rover suffered from the first dust storm in 2007, which fought the problems in the center of the wheel and worked on a robotic arm problem throughout its expedition.
However, it seems that no one can knock out a valiant robotic explorer. In its 5,000th Martian day, it is celebrated in its first selfie.
The opportunity will remain asleep in the Perseverance Valley, which is sometimes spied by a passing orbiter – or perhaps, in the distant future, acquired and idolized as a pioneer who teaches the way to reach first humans, and even live in, Mars.
"Because of trailblazing missions such as Opportunity there will be one day when our brave astronauts are walking over Mars," Bridenstine says.
NASA's Curiosity rover robot survived, which remains the only active rover over the Martian. It was joined by NASA'sand the Rover of the European Space Agency, set in 2020.
NASA turns 60 : mankind is far more than anyone else, and there are plans to continue.
