The habitability in the Red Planet is measured by using high-resolution cameras, sensors, drillers and laser.The ChemCam laser delivers over a million watts of power, in short laser bursts is over five one-billionths of second. Vaporizing the rock in creating a plasma.
The hole diameter is less than 4 millimeters, was formed by 100 laser blasts from 2.75 meters (9 feet) away. A new animation released by NASA that shows 16 photos of Curiosity’s ChemCam instrument. The small hole is generated by the shock wave blasting through the rapidly expanding ionized gas is then analyzed by the ChemCam’s sensitive optics to decipher what are chemicals the material it composed of.
Through this process scientists at this mission, provide the info about how the rocks were created and what the environmental conditions have been in Mars in ancient past.
