The Curiosity rover landed on Mars without a gravimeter on board. But researchers realized that its accelerometers--normally used to determine the position of the rover--could be repurposed to measure the density of the rock it was passing over. These measurements can help scientists understand how Gale Crater and Mt. Sharp came to be.
