  • What’s more likely to happen is Starship’s will be launched where the entire ship becomes the telescope, and then we’ll have arrays of these much further away.

    Not sure if it’s the same for radio, but for optical that means we can get a 9 meter mirror up there without any expensive folding mechanism, and who knows how big if we fold them as the fairing is not only wider but also longer.

    Cost would go from billions to hundreds of millions or less. James Webb cost 10b.

    The James Webb folding mirror is 6.5m and was folded into a 4.5m fairing…




















  • My bet is they were just told it was a fire, i doubt the person to drive by and report it would have known it was an electric truck.

    The batteries definitely do have fire protections, to help delay the spread. Dousing it with 50k gals of water may have prevented the spread to another compartment for all we know. For something as big and higher risk like a semi though maybe there’s a way to eject compartments. Like if a fire starts in Module 1 of 4, modules 2 to 4 can eject themselves further away. Then were only dealing with a 250kwh fire instead of a 1mwh fire. It would add weight though.

    Edit: And then while the firefighters keep the flames at bay, something could get attached to the other compartments and be dragged further away.
