NASA's laser-shooting Mars rover can now choose its own targets
Recently, NASA gifted its Martian explorer with the ability to pick and choose which space rocks to zap with its laser.
Using something called the Chemistry and Camera instrument (ChemCham), the rover picks a target and shoots laser pulses at it.
Over the course of the Curiosity Rover's life on Mars, scientists have used its tiny laser to inspect more than 1,400 targets. This took more than 350,000 laser blasts in 10,000 different places.
By looking at the light signatures that different rocks produce when the laser hits, scientists can figure out which elements are in them.
"ChemCam data could show how Mars' environment went from potentially fertile to barren and unsuitable for biological life as we know it," Popular Science reports.
Now, using the Autonomous Exploration for Gathering Increased Science software (AEFIS), the intrepid rover can make its own decisions about which rocks it wants to vaporize based on the size and color of the rocks.
"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, the leader of AEGIS development at JPL, said in a press release.
But NASA hasn't completely taken the training wheels off just yet. According to the press release, most of the ChemCam's targets are still selected by humans back on Earth.
One day, little Mars rover. One day.
