NASA, the US space agency said that the Perseverance rover did not collect a rock sample on Mars in its first attempt.
Earlier last month, the self-driving six-wheeled robot started it's mission across Jezero Crater floor to search signs of ancient life.
During the mission, the robot while using it's 2-metre-long robotic arm, drilled a hole on Mars but it could not collect and store samples as required.
NASA said in a statement, "Telemetry from the rover indicates that during its first coring attempt, the drill and bit were engaged as planned, and post-coring the sample tube was processed as intended".
"But recent data sent to Earth by NASA's Perseverance rover after its first attempt to collect a rock sample on Mars and seal it in a sample tube indicate that no rock was collected during the initial sampling activity", it added.
The space agency is currently working on the problem and intends to resolve the issues regarding AI or hardware which might be found.
