A martian rock named "Coronation" was shot with 30 pulses over a 10-second period by Curiosity's laser
today in order to determine what elements it was made of. “We got a great spectrum of Coronation — lots of signal,” Roger Wiens of Los Alamos National Laboratory, leader of the ChemCam scientific team, said in a press release today. “Our team is both thrilled and working hard, looking at the results. After eight years building the instrument, it’s payoff time!” Another rock known as N165 was selected for later testing.
