Washington DM  - It is the nearest there has ever been a nightclub on another planey. Nasa today revealed video footage showing its Curiosity rover firing lasers on the red planet. The ChemCam laser instrument has zapped more than 600 rock and soil targets on Mars since Curiosity landed in the planet’s Gale Crater in August 2012 - but this is the first time the process has been seen. The flashes appear on a baseball-size Martian rock in a series of images taken on Saturday by the Mars Hand Lens Imager (MAHLI) camera on the arm of NASA’s Curiosity Mars Rover.

The flashes occurred while the rover’s Chemistry and Camera (ChemCam) instrument fired multiple laser shots to investigate the rock’s composition.

‘This is so exciting! The ChemCam laser has fired more than 150,000 times on Mars, but this is the first time we see the plasma plume that is created,’ said ChemCam Deputy Principal Investigator Sylvestre Maurice, at the Research Institute in Astrophysics and Planetology, of France’s National Center for Scientific Research and the University of Toulouse, France.

‘Each time the laser hits a target, the plasma light is caught and analyzed by ChemCam’s spectrometers.

‘What the new images add is confirmation that the size and shape of the spark are what we anticipated under Martian conditions.’

Preliminary analysis of the ChemCam spectra from this target rock, appropriately named ‘Nova,’ indicates a composition rich in silicon, aluminum and sodium, beneath a dust layer poor in those elements.

This is typical of rocks that Curiosity is encountering on its way toward Mount Sharp.

MAHLI Deputy Principal Investigator Aileen Yingst of the Planetary Science Institute, Tucson, Arizona, said, ‘One of the reasons we took these images is that they allow the ChemCam folks to compare the plume to those they imaged on Earth.

‘Also, MAHLI has captured images of other activities of Curiosity, for documentation purposes, and this was an opportunity to document the laser in action.
