Curiosity, NASA’s only rover still working, landed on Mars in 2012 and has been in operation for more than seven years, but it was shut down this week because of a malfunction. Curiosity stores positional data such as orientation in memory, and it needs to assess position sits to ensure safe travel before the wheel moves, preventing rocks or unprotected cameras from pointing at the sun.
But earlier this week, its location information was lost, it stopped moving, waiting for the direction information to recover.
NASA engineers have solved the problem. Curiosity is currently climbing the 5.5-kilometer-high Mount Sharp mountain, reading rock records for clues to the changing climate of Mars – how the Red Planet has gone from a relatively warm and humid place to a cold desert world.
