On SLS

This is an excellent takedown of NASA's SLS (Space Launch System). I've been followed this fiasco on and off for years and am still flabbergastered by how much money has been wasted. If not cancelled soon I hope a RUD (rapid unscheduled disassembly, as SpaceX refers to them) occurs in the first flight, leading to the plug finally being pulled.

First I downloaded every data set from this  archive  page, going back to May 2020 (where the archived data begins, so note that Month will also include all deaths earlier in the year).

On what if scenarios: London goes boom!

 Scott Lowther ponders this after viewing a clip of London getting wipe out by an orbital kinetic weapon (AKA Project Thor ). I started to leave a comment but as it got longer and longer I decided to post here instead. So, let's go through some of his questions and try to make a realistic prediction: First, he posits ' would this utterly trash Britain?' he also states ' London is responsible for a whole lot of the British economy, but it’s sorta the “fake” economy of financial stuff, not growing stuff or making stuff.' Well, first off there is the issue of all the banks being vaporized, along with all their ICT systems. I'd hope they have backups but it could be that the entire payments system ceases to function. The result for the rest of the UK would be no one would be able to use a credit or debit card, withdraw cash or even access their accounts. Guess we'd be back to cash pretty sharpish.  In addition, all the insurance underwriters (Lloyds, etc) wou...
