As Passport to Knowledge reported, Spirit had just survived the six-month journey to the Red Planet and a perilous landing, including bouncing as high as a four-story building on first impact with the surface. The Jet Propulsion Laboratory (JPL) team that built and commanded the rover thought the worst was behind them. They were wrong.
Once the (literal) dust—red—had settled, Spirit began its mission of taking pictures and performing scientific experiments, rolling toward a nearby destination (“Sleepy Hollow”). But then on January 21, less than three weeks into the mission, something happened. NASA’s Deep Space Network lost contact with Spirit.
At first, the rover’s disappearance was blamed on a thunderstorm in Australia disrupting the network, but no, there was something wrong with Spirit itself.
