Since June 2018, after a huge sandstorm swept the Martian sky and covered the sun, Opportunity has remained silent. The storm was one of the thickest Martian storms NASA had ever seen, making it impossible for Opportunity's solar panels to remain powered. As a result, the internal battery of the opportunity number is exhausted and the opportunity number enters the sleep mode After the sandstorm, the Opportunity Task Team was full of hope, and they hoped to wake up the Opportunity again. They believe that once the light hits the Opportunity solar panel again, it can get enough energy to turn on the power and establish radio contact with the Earth. But since the opportunity letter was sent back to the last piece of information on June 10, continued silence indicates that the Opportunity Battery is almost exhausted.
The team has tried every possible method to re-contact Opportunity with NASA's Deep Space Network, a series of large radio telescopes on Earth that communicate with spacecraft deep in the solar system. But no success. One theory is that sandstorms leave a layer of dust on the solar panels that further prevents it from receiving sunlight. However, NASA is still full of hope, because November to January is considered to be a particularly windy season on Mars, and engineers hope that powerful gusts can blow away dust from solar panels. Now, with the Mars car coming into Mars winter, the Opportunity is almost certain to be dead.
