The mission’s ChemCam instrument hit a fist-sized rock named “Coronation” with 30 pulses of its laser during a 10-second period. Each pulse delivers more than a million watts of power for about five one-billionths of a second.
The energy from the laser creates a puff of ionized, glowing plasma. ChemCam catches the light with a telescope and analyzes it with three spectrometers for information about what elements are in the rock.
NASA said the main function of this was target practice to calibrate the ChemCam.
You gotta love the sense of play NASA is bringing to this mission. Not only are they releasing these stories about test-firing lasers, but they are all over social medial, including fan art on Facebook, a first-person Twitter account, sharing stories on Google Plus, and posting articles on their much more user-friendly website.
A great idea for the much beleaguered space agency, that I assume is a bid to get them back into America’s good graces…and taxpayer dollars.
