This work reports the investigation of low-energy, eye-safe laser-induced breakdown spectroscopy (LE-LIBS) feasibility for in situ detection of gaseous elements significant to the planetary surface chemistry. A ns-pulsed laser emitting pulses of energy of 3 mJ at 1.54 μm wavelength is used to ablate soil pellet samples. Plasma emission spectra are acquired in the spectral window of 220–800 nm employing a concave flat-field spectrograph.
