In December 2016, a key component of the Curiosity rover’s drill on Mars stopped working, making it impossible to use the tool as designed. The drill had successfully completed 15 operations before the failure, which involved a mechanism known as the feed system. This system was essential for extending the drill into the rock. Since Mars is about 225 million kilometers away from Earth, it is not possible to physically repair the rover, so engineers had to rely on existing systems on board to find a workaround. A breakthrough came in August 2017, when engineers managed to extend the drill fully over a distance of about 110 millimeters. This success allowed them to rethink how to completely bypass the failed mechanism. They devised a new method called Feed Extended Drilling (FED), which involved using the rover’s robotic arm to push the drill directly against the rock while also applying a hammering motion. This technique enabled drilling to resume after nearly two years of inactivity. Since landing on Mars in 2012, Curiosity has drilled into the Martian surface 42 times. The rover gained a strong reputation for its ability to extract rock powder samples, which it then analyzed using onboard scientific instruments. Before the failure, the drilling process used a system with two hooks to stabilize the drill and an internal motor to advance it. However, after the feed mechanism failed, the team had to adapt their methods to continue the mission. After successfully drilling a hole 50 millimeters deep in a rock called Duluth, the team faced the challenge of transferring the collected powder to the instruments for analysis. They developed a technique called feed extended sample transfer, which involved rotating the drill in reverse to create a gentle vibration that helped the powder move. This method worked like shaking a salt shaker to get the contents to fall onto a plate. The failure of the drill and the subsequent solution demonstrated the adaptability and creativity of the teams working on Mars missions. The deputy project manager for Curiosity at NASA’s Jet Propulsion Laboratory praised the team’s ingenuity in overcoming this challenge. The new drilling method has proven effective, allowing the rover to reach 42 successful drillings since its landing. This story shows that space exploration is as much about human creativity and problem-solving as it is about advanced technology.
