    First detection of the plume created by the crash of the SpaceX spent upper stage into the moon last night.

    Spectroscopic measurements taken with the UVES instrument at the VLT in Chile show emission lines of sodium & lithium in the plume that lasted for 5-10 minutes after impact.

    The sodium likely originated from the lunar soil, whereas the lithium could come from the rocket itself.

      Attached: 1 image 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.
