 Thanks to its sophisticated equipment, Curiosity was able to find evidence of past habitable environments on Mars based on chemical and mineral findings early in its mission.\cite{marsnasagov_chemcam}
 
 One of the instruments aboard the rover is the \gls{chemcam} instrument, which is a remote-sensing laser instrument used to gather \gls{libs} data from geological samples on Mars.
-\gls{libs} is a standoff technique that enables rapid analysis without the need for sample preparation by using a laser to ablate and remove surface contaminants to expose the underlying material and generate a plasma plume from the now-exposed sample material\cite{wiensChemcam2012}.
+\gls{libs} is a technique that enables rapid analysis by using a laser to ablate and remove surface contaminants to expose the underlying material and generate a plasma plume from the now-exposed sample material\cite{wiensChemcam2012}.
 This plasma plume emits light that is captured through three distinct spectrometers to collect a series of spectral readings.
 These spectra consist of emission lines that can be associated with the concentration of a specific element, and their intensity reflects the concentration of that element in the sample.
 Consequently, a spectra serves as a complex, multi-dimensional fingerprint of the elemental composition of the examined geological samples.\cite{cleggRecalibrationMarsScience2017}
