SpaceX rocket vs Moon impact plume detected by @eso.org spectral analysis. Na — likely from lunar regolith, Li — may be from the discarded Falcon 9 rocket stage itself.
Earlier today, the discarded upper stage of a Falcon 9 rocket impacted on the Moon. As part of a coordinated observing campaign, our Very Large Telescope detected spectral lines of sodium and lithium gas in the impact plume lasting for 5-10 minutes after impact. 🔭 🧪 📷 ESO/C. Schmidt et al. 1/4
