Mission engineers uploaded new software that aimed to resolve the memory issue of Mars Rover

NASA’s Opportunity Mars rover has endured another episode of amnesia, not as much as a week after engineers of Mars rover installed a software program for the purpose of resolving the robot’s memory issues.

The extensive Opportunity rover started encountering issues with its flash memory — the kind that can store information although the power is off — in late 2014. On March 20, mission Mars Rover engineers uploaded new software that intended to resolve the issue by bypassing an evidently flawed “bank.”  (The rover has seven such flash memory banks.)

Yet Opportunity experienced another brief amnesia scene on March 25, NASA authorities said.

“Although we are a little disappointed at the occurrence of an amnesia event only five days after reformatting, we are not surprised,” According to John Callas, Opportunity project manager at NASA’s Jet Propulsion Laboratory in Pasadena, California. There is still no clear understanding of what is causing the problems. Only time will tell if we have been successful in mitigating the most serious flash problems.”

Opportunity was encountering various computer resets every prior day mission colleagues started working the rover in a “no flash memory” mode in December. No such serious issues have reemerged since the March 20 reformatting, NASA authorities said. The brief March 25 occasion didn’t bring about the loss of any science information, and Opportunity continued its work shortly thereafter.                                                                                                                                                                                                                                                                                                                                                                     Opportunity and its twin, Spirit, touched down three weeks separated in January 2004 to search for signs of past water activity on Mars. Both rovers discovered a lot of such proof and kept on working long beyond their initial three-month prime missions: Spirit quit speaking with Earth in 2010, and Opportunity is as yet moving along.

For sure, a week ago Opportunity finished the first-ever marathon beyond Earth when its odometer ticked over to 26.219 miles (42.195 kilometers). Second place in the off-world driving rivalry belongs to the Soviet Union’s Lunokhod 2 rover, which voyaged 24.2 miles (39 km) on the moon in 1973.
