Mysterious signal from Mars : NASA reveals having received a mysterious signal of unknown origin from Mars
The robot rover Opportunity (MER-B), active on the planet Mars since 2004, communicated for the last time with Earth on June 10. A strong dust storm that spread across the red planet blocked the sun and deprived the rover of solar energy, putting it in an inactive mode.(Mysterious signal from Mars)
On Sept. 11, NASA’s Jet Propulsion Laboratory said the optical depth had dropped to a level low enough to allow enough sunlight to reach the rover for power. At that moment, a procedure known as “active listening” was activated , in which the commands were transmitted to the robot in case it could not be activated and to be able to hear some response.(Mysterious signal from Mars)
After more than a month, Opportunity has not responded to those commands, and active listening will soon be over. As explained by NASA, if no response is received after 45 days, the team will be forced to conclude that the dust and Martian cold has caused some kind of failure of which the rover probably will never recover, It will be the death of Opportunity.
