NASA makes last ditch attempt to revive dormant Mars rover Opportunity

Now NASA scientists are trying a last ditch attempt to contact the rover based on three unlikely but possible scenarios: that the rover’s primary X-band radio has failed, that both the primary and secondary X-band radios have failed, or that the rover’s internal clock has become offset. The team is commanding the rover to switch to its backup X-band radio and to reset its clock to counteract these possibilities.
“While we have not heard back from the rover and the probability that we ever will is decreasing each day, we plan to continue to pursue every logical solution that could put us back in touch,” John Callas, project manager for Opportunity at NASA’s Jet Propulsion Lab, said in a statement.
These strategies are becoming urgent due to the seasonal changes on Mars. The season of high winds which could clear the dust from Opportunity’s solar panels is coming to an end and soon southern winter will be arriving, which means very low temperatures that are likely to cause irreparable damage to the rover’s systems. NASA will try sending the new commands for several weeks, but if Opportunity doesn’t respond this time, then it’s likely that the mission will have to be abandoned.
