Perseverance lands to pursue answers to life on Mars using XRF
Dr. Andrew Czaja, University of Cincinnati | Geology
Dr. Andrew Czaja of the University of Cincinnati assists NASA’s Mars 2020 Perseverance mission by selecting promising rock samples from Jezero Crater that may preserve signs of ancient life. On Mars, PIXL (XRF) and SHERLOC (UV Raman) instruments measure elemental and organic signatures in situ. Back on Earth, Czaja plans to analyze returned Martian samples using a HORIBA T64000 Raman spectrometer to detect organic carbon and potential microbial textures. His work aims to identify biosignatures and inform future assessments of past Martian life.
