“ A #telescope in #Chile has captured evidence of the impact caused by part of a SpaceX #Falcon9 rocket slamming into the moon while travelling at 8,690km/h (5,400mph). The European Southern Observatory’s (ESO) Very Large Telescope observed “spectral lines” – a colourful illustration of the #sodium and #lithium gas – in the plume of #LunarDust stirred up by the impact. The #ESO telescope recorded these “chemical fingerprints” of the plume, which were visible for five to 10 minutes, the #observatory said. The #plume measured a few tens of kilometres in size, according to #CarlSchmidt, an astronomer from #BostonUniversity’s Center for #SpacePhysics.” #Moon

it's interesting to see the first #sodium ion batteries show up on alie, they're still more expensive than lifepo4 right now, but they already have the advantage of working in low temperatures like -40C without any differences, having a decently high discharge rate (5S pulse and 20C continuous), and being intrinsically more stable and safe than anything with lithium .. tempted to get some and do some torture testing to see if they catch on fire or whatever if you stab them like with #lithium 🤔
