a, The locations of fresh craters used in the spectral analysis. Base map from CE-2 DOM. b, The absorption centres of pyroxene of varying composition (1 versus 2 μm); blue solid circle, samples of F; light blue solid circle, samples of L; dark green solid circle, samples of B (large craters); light green solid circle, samples of B (small craters); light orange solid circle, Apollo inner ring floor; orange solid circle, Apollo east outer rim; solid triangle, mare basalts of the CE-5 landing area; solid diamond, CE-5 returned samples; black hollow circle, laboratory (lab) measured augite; hollow triangle, laboratory measured pigeonite and hollow square, laboratory measured orthopyroxene. Data for F, L, B, Apollo inner ring floor, Apollo outer rim and CE-5 mare basalts were derived from M3 orbital data. Data for CE-5 samples and lab measured pyroxene are from Liu and Wang et al.47 and Klima et al.50, respectively. The spectrum analysis method is similar to ref. 47 (Methods).
