“…Above expectations were validated by our experimental observations (Wu et al., 2018) of CO 2+ , CO + , O I , H III , H II , OH, Ar I , N 2 , N 2 + by in situ plasma emission spectroscopy (also O 2 , NO, and O + because of the overlapping of plasma lines used for detection, Figure ) and O 3 in the output gas by UV and mid‐IR spectroscopy (Figure 5 of Wu et al., 2018), generated by normal glow discharge (ESD‐NGD) under simulated Mars atmospheric composition and pressure. During a simulated saltation experiment on silicates upon contact of water (Bak, Zafirov et al., 2017), H 2 O 2 and •OH were detected. Furthermore, Aerts et al.…”
