SHERLOC

SHERLOC, which stands for "Scanning Habitable Environments with Raman & Luminescence for Organics and Chemicals," is a scientific instrument on NASA's Mars rovers. It uses laser light to analyze minerals, chemicals, and organic molecules on the Martian surface. By examining how these substances interact with laser energy, SHERLOC helps scientists detect signs of past life and understand the planet’s geology and habitability. Essentially, it acts like a highly sensitive, hand-held laboratory, providing detailed information about the composition of Martian rocks and soils from a distance, guiding further exploration and sample collection.
