The disappearance of a robot on Mars is prompting NASA to abandon and terminate its mission.

NASA has announced the end of the Marshal Obercroft robotic mission on Mars.

The six-wheeled Obi robot sent signals to the Earth the last time in June before disappearing in the darkness of the dust from space.

The engineers had hoped that the Obi robot would return to the signals, once night fell and the dust removed, the light returning to its solar panels, but they received nothing from him.

It was decided today not to send instructions to the robot and to announce the end of its mission.

"We have been trying to recover the robot for eight months," said John Calas, director of the program: "We were listening daily with the help of sensors, we were sending out more than a thousand instructions, we were not sure about it. I heard nothing and it was time to warn him.

What is the importance of this decision?

This decision puts an end to one of NASA's most successful missions.

Robbie Obey and his companion Spirit landed on Mars in January 2004 to test the conditions necessary for life on the planet.

The team estimated that the robot would work 90 days on Mars and could walk at a speed of 1 km per hour.

But the little robot has exceeded all expectations.

Spirit worked 6 years, traveling at 8 km / h, and Obi had a speed of 45 km / h for more than 14.5 years, a record for these all-terrain vehicles.

What are the achievements of Android?

The robot sent some very important scientific information. This information proved that the planet was not as cold as it is today, but warmer and wetter.

Indeed, there is evidence of rocks that the robot has observed on the existence of streams on or below the surface for long periods of time.

Obey discovered these facts once he landed on Mars in an eagle den named Bass.

Robot cameras have spotted small balls called strawberry berries, for their shape and small size. These stone blocks contain iron oxide, usually formed by the presence of water.

Scientists have shown that this water is acidic and does not help life. But the information provided by the mission eventually revealed mineral sludge, revealing more viable conditions.

"We have detected the presence of rocks in which the flow of water is determined by a neutral acidity, which means that it is drinkable – and that is the greatest discovery of the task, "said Steve Squires, chief scientist at Cornell University.

What legacy did the robot leave?

Abigail Freeman, an expert in project assistant, was in high school when the robot landed on Mars and witnessed her landing with scientists after winning a contest among schoolchildren.

"Hundreds or thousands of students like me attended the robot's landing and followed his mission through images published over the past 15 years, so they decided to study the science and mathematics, "explains Ebeigel.

Geometrically, the robot says that it is possible to build bigger and more solid machines for Mars exploration. Previous devices, including mobile devices, have limited capabilities.

What's left is his work on Mars?

The project stopped working with the lost robot only on Mars. Another robot, named Kurosieti, also landed on Mars in 2012 and is equipped with a plutonium battery that allowed it to easily get out of the darkness and the latest flares of the planet.

NASA is preparing another robot Robusti type that should be sent to Mars in 2021. Another robot will join later in the month, but it will land in a different area.

The US space agency has sent another fixed device called Insight, which landed on Mars last November.
