Thales SuperCam laser prepares to follow ChemCam to Mars in 2020

Selected again for NASA’s Mars exploration programme, Thales has now delivered the laser for the SuperCam instrument to the French space agency CNES, which is partnering NASA for Mars 2020. The SuperCam laser developed by Thales is an evolved version of the ChemCam laser on Curiosity.

The ChemCam laser developed by Thales for CNES was the first-ever power laser to operate on another planet. ChemCam is still hard at work on Mars and has fired over 500,000 times to date.

The SuperCam laser developed by Thales is an evolved version of ChemCam. As well as the laser-induced breakdown spectroscopy (LIBS) system used on ChemCam, the SuperCam instrument also features a non-destructive Raman spectroscopy mode for the analysis of molecular vibration energies. This analysis technique has never been tested on Mars and will be used to look for the possible indicators of life.

''The powerful image of the Curiosity rover arriving on Mars in 2012 regularly came to mind during the development of SuperCam — especially when we were making choices that could impact the laser’s robustness and durability.'' Eric Durand, head of the SuperCam programme at Thales’s optronics business

Delivering the new SuperCam laser is a real challenge, not least because it packs additional functions into a unit the same size as the ChemCam laser, as well as the system that allows operators to switch between the LIBS and Raman modes.

Beyond the size restrictions, the teams have also significantly increased the instrument’s analysis capabilities. The SuperCam laser can produce 10 times as many shots in burst mode for faster sampling — 1,000 shots per burst, compared to a maximum of 100 with ChemCam and at a frequency three times higher (10 Hz). All this has been achieved in an extremely short timeframe of just three years, whereas a typical space programme would have a development cycle of nearer 10 years.
 
Thales has made innovation a core strategic priority and believes that real innovation hinges on the ability to harness creativity to meet actual customer needs and develop disruptive technologies. The company’s high-power lasers help advance research with practical applications in industry, nuclear energy and the medical sector. A total of almost 60 laser systems are in operation worldwide.Selected again for NASA’s Mars exploration programme, Thales has now delivered the laser for the SuperCam instrument to the French space agency CNES, which is partnering NASA for Mars 2020.
