Remote sensing of chiral signatures on Mars



William Sparks, James H. Hough, Thomas Germer, Frank Robb, Ludmilla Kolokolova


We describe circular polarization as a remote sensing diagnostic of chiral signatures which may be applied to Mars. The remarkable phenomenon of homochirality provides a unique biosignature which can be amenable to remote sensing through circular polarization spectroscopy. Observations of selected areas of the Mars surface could reveal chiral signatures and hence explore the possibility of extant or preserved biological material.
