Laboratory Investigations of the Complex Refractory Organic Material Produced from Irradiation of Pluto Ice Analogs - NASA Technical Reports …

2014/11/9· Our latest work has consisted of the analysis of refractory materials produced from the electron boardment of low temperature N2(‐), CH4(‐), and CO(‐)containing ices (100:1:1). The ice mixture was chosen to be analogous to the known surface ices on Pluto and the radiation source was chosen to mimic the secondary electrons produced by cosmic rays boardment.
