Dust storms of planetary scale began in June 2018, the clouds in this period can reach 60 miles high, so the researchers had to translate the Rover in crisis mode - because Opportunity gets energy to work through solar panels.
So, according to Space.com, staff at NASA's Jet Propulsion Laboratory in Pasadena, California, have been playing themed wake-up songs in the control room, in an effort to inspire the sleeping rover to awaken. So far, it hasn't sent a beep back.
"A variety of scientists think early to mid-September might be a time when the skies clear enough that it could recharge", Andrew Good, Mars and Mars technology media relations specialist, told "Inverse". The last time NASA heard from Opportunity was June 10. "We still haven't heard from it".
The Mars Opportunity rover, which was launched way back in 2004, is now the longest-serving rover on the Martian landscape. Dust storms usually occur in summer, when the Red planet comes to perihelion (closest to Sun point of the orbit). Since the last contact with the rover, Opportunity has likely experienced a low-power fault and perhaps, a mission-clock fault.
While the team is not expecting to hear anything from Opportunity up until there is a significant decrease in the atmospheric opacity brought by the dust storm, engineers manning the control room would like to take matters with their own hands through their carefully chosen song list. "Additionally, the up-loss timer has also since expired, resulting in another fault condition", the space agency said in a statement.
However, this doesn't leave NASA without any spacecraft to keep an eye on the Red Planet, as the Curiosity rover, which runs on nuclear power, is now studying geological formations on the other side of Mars. Its other rover, the selfie-taking Curiosity, continues to study geological formations on the other side of the planet.
