Meteoritics &Planetary Science, EarlyView.Abstract
In the search for life on Mars, understanding the origin of preserved organics is critical. Expected sources include exogenous delivery, endogenous synthesis, and potentially life. Environmental processing by ultraviolet (UV) irradiation can alter these organics, obscuring hallmarks of their origin. To deconvolve these effects, we conducted an D. K. Buckner, J. C. Aponte, A. C.
