Look out, Mars: NASA's Curiosity rover can now fire its onboard laser all by itself.
The car-size Curiosity rover recently began autonomously choosing some of the targets for its ChemCam instrument, which blasts Martian rocks or soil with a laser and analyzes the composition of the resulting vapor.
Mission scientists here on Earth still select most ChemCam targets, after poring over images captured by the rover, NASA officials said. But Curiosity's increased independence comes in handy.

"This autonomy is particularly useful at times when getting the science team in the loop is difficult or impossible - in the middle of a long drive, perhaps, or when the schedules of Earth, Mars and spacecraft activities lead to delays in sharing information between the planets," robotics engineer Tara Estlin, of NASA's Jet Propulsion Laboratory in Pasadena, California, said in a statement.
Estlin led the development of the software that allows Curiosity to pull ChemCam's trigger automatically, which is called Autonomous Exploration for Gathering Increased Science (AEGIS).
"To select a target autonomously, the software's analysis of images uses adjustable criteria specified by scientists, such as identifying rocks based on their size or brightness," NASA officials wrote in the same statement. "The criteria can be changed depending on the rover's surroundings and the scientific goals of the measurements."
