"The surface of the Earth is the shore of the cosmic ocean... Recently, we've managed to wade a little way out, and the water seems inviting." - Carl Sagan
THE RESULTS ARE BACK FROM CURIOSITY’S FIRST LASER TEST!
Curiosity’s spectrometers recorded data on 6144 channels, ranging from ultraviolet to infrared light from 240 to 850 nanometers. This is an image of this spectrum, and was sent back from Mars on August 19, 2012.
There are emission lines from different elements, including oxygen, silicon and sodium; also some minor elements like titanium and manganese. The high carbon peak comes from the atmosphere of Mars, not from the rock zapped. The peak indicating hydrogen came only from the first laser shot, which suggests this element was only present on the surface of the rock.
