NASA's Peculiarity wanderer
recently began autonomously choosing some of the targets for its ChemCam instrument. The car-size robotic rover
exploring Gale Crater 'Curiosity' itinerant recently began autonomously
choosing some of the targets for its ChemCam instrument which crack Martian rocks
or soil with a laser and analyses the composition of the resulting vapor. NASA Scientists
still selects most ChemCam targets after peruse over images captured by the drifter.
And Curiosity's increased independence comes in useful. This autarchy is particularly useful at times
when getting the science team in the kink 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 of NASA said in a statement.
To select a target autonomously the
software's analysis of images uses variable basis specified by scientists, such
as identifying rocks based on their brightness
or size, NASA officials said. The criteria can be changed depending on
the rover's surroundings and the scientific goals of the measurements. ChemCam
sits a top Curiosity's head-like mast. The instrument can investigate the
composition of a target that is up to 23 feet (7 meters) away from the rover. Using
a suite of different instruments the rover quickly found evidence that Gale was
a potentially habitable lake and stream system billions of years ago. During the
four years on Mars, Curiosity has used ChemCam to analyse more than 1,400
targets, firing off more than 350,000 laser blasts in the process, NASA
officials said.
