Most recently, the rover's engineers at NASA placed the rover on a spin table and rotated it clock and anti-clockwise. This seemingly trivial exercise was done to find the rover's centre of gravity, now that the rover is fully-built and tested. This key step in the rover's development will help NASA engineers ensure the rover travels safely on Martian terrain. Based on what they find, the engineers will add weights as needed, ensuring the vehicle is balanced.
