Stupid, again. Japanese Sciences Society. JAXA has decided to withdraw the scientific paper which has been submitted to Science and printed: X-ray fluorescence spectrometry of asteroid. X-ray fluorescence spectrometry of asteroid 25143 Itokawa was performed by the x-ray spectrometer onboard Hayabusa during the first touchdown on 19 November 2005. We selected those data observed during relatively enhanced solar activity and determined average elemental mass ratios of Mg/Si = 0.78 ± 0.09 and Al/Si = 0.07 ± 0.03. Our preliminary results suggest that Itokawa has a composition consistent with that of ordinary chondrites, but primitive achondrites cannot be ruled out. Among ordinary chondrites, LL- or L-chondrites appear to be more likely than H-chondrites. No substantial regional difference was found on the asteroid surface, indicating its homogeneity in composition. sciencemag.org/content/312/5778/1338.abstract?sid=6accac96-be35-462e-99c8-bda993b0e5a4
