NASA's Curiosity rover accidentally pulled out a rock while drilling into Martian surface. Engineers freed the rock after several attempts.

The NASA Curiosity rover is designed to explore Mars and collect samples from its surface. Recently, it encountered an unexpected situation when a rock became stuck to the drill at the end of its robotic arm. The rock, estimated to be about 1.5 feet across and weighing around 28.6 pounds, was attached to the fixed sleeve surrounding the spinning drill bit. Engineers tried to remove it by vibrating the drill, but this attempt had no visible effect.

After a few days, they adjusted the position of the robotic arm and activated the drill vibration again. This time, sand spilled from the rock during the attempt, but it still didn't detach. On May 1, engineers made another attempt using a combination of steeper drill angles, drill rotation, vibration, and spinning of the drill bit. To their surprise, the rock broke free during the first attempt and fractured apart when it struck the Martian ground.

The Curiosity rover is part of NASA's Mars Exploration Program, which aims to explore the Red Planet and uncover its secrets. The mission has been ongoing since 2012, with the rover collecting valuable data and samples from Mars.
