NASA's Mars Curiosity rover is once again piloting science after experiencing a memory anomaly in September. The rover drove about 60 meters over the past weekend to a site called Orcadie Lake, pushing its total odometry to more than 20 kilometers. It was the longest ride of Curiosity since September 15, 2018, date of the day when a memory anomaly had been committed. The mobile rocked to a backup computer, called Side-A computer, Oct. 3.
Like many other spaceships, Curiosity was designed with two redundant computers – in this case, called side A and B computers – so that they could continue their operations in case of a problem. After considering several options, the JPL engineers recommended that the mobile move from side B to side A.

The NASA Reaction Propulsion Laboratory Curiosity Engineering Team continues to diagnose the anomaly found on the B-side computer. Curiosity first used the Side A computer. , after landing on Mars in August 2012. Side More than five years ago, NASA was experiencing hardware and software problems, NASA said, leaving the mobile uncontrollable and unloading its battery. At that point, the team successfully switched to side B. The engineers have since diagnosed and quarantined the affected A side of the memory, so that the computer is available again for mission. Steven Lee of JPL is the Deputy Project Manager of Curiosity. Lee said in a statement:
At this point, we are certain to resume our operations, but it is too early to say when. We are working on the A side as of today, but it may take time to fully understand the root cause of the problem and find workarounds for the B-side memory.
We have spent last week checking Face A and preparing it. the swap. It is certainly possible to run the mission on the Side-A computer if we really need it. But our plan is to go back to face B as soon as we can solve the problem in order to use its largest memory size.
Result: NASA's Mars Curiosity rover has made its longest run since an anomaly in memory on September 15, 2018..
