NASA Mars Curiosity rover drives and carries out science after experiencing an anomaly in memory in September. Last weekend, Rover drove about 60 feet (60 meters) to a site called Lake Orcadie, pushing its total mileage over 12 miles (20 kilometers). This was Curiosity's longest drive since it experienced an anomaly of memory on September 15, 2018. Rover moved to a backup computer called the Side-A computer on October 3.
As with many space ships, the Curiosity is designed with two redundant computers – in this case, it is called Side-A and Side-B computer – so it can continue to work if someone experiences a problem. After reviewing several options, JPL engineers recommended that the rover switch from side B to page A.
The Curiosity Engineering team at NASA's Jet Propulsion Laboratory continues to diagnose the anomaly on the Side B computer. Interestingly, the Side A computer was used initially after it landed on Mars in August 2012. Experienced hardware and software problems more than five years ago, NASA said, leaving the router unwashed and running its battery. At that time, the team successfully crossed over to page B. Engineers have since diagnosed and quarantined part of the Side A memory that had been hit so that the computer was again available to support the mission. Steven Lee of the JPL is the deputy head of the project Curiositi. Lee said in a statement:
At this moment, we are convinced that we will return to full operation, but it is still early to say how fast. We are currently working on Side A, but we should take the time to fully understand the underlying cause of the problem and make Solution Memory solutions for Side B.
Last week, we checked page A and prepared it for replacement. It's safe to run a mission on a Side-A computer if we really need it. But our plan is to return to Side B as soon as we can solve the problem of using a larger memory size.
