Incredible view of SpaceXโs Super Heavy static fire ahead of Starship Flight 14. ๐๐ฅ
Itโs crazy that the public can witness something this powerful from so close!
SpaceX engineers spent several days inspecting Ship 40 in the waters off Christmas Island. They collected heatshield samples and gained vital insight into how the vehicle handled reentry with improvements now planned on future vehicles
The Scissor Test.
Within the first few weeks of me joining TBC, Steve gave me the direction that he wanted to be able to walk around a Prufrock with a pair of scissors, be able to cut any wire, and the machine should still be able to mine.
Obviously this was a hypothetical exercise, but the goal was real.
What followed was a deep system-wide failure mode effects analysis and a complete redesign of the machineโs electrical system to be able to pass the scissor test. There are still a few single points of failure where the complexity or cost tradeoff doesnโt make sense to design out, but for the most part Prufrock now passes the scissor test.
Being robust to a single failure is obviously important, but equally as important is observability of those failures. Without observability, a failure can lay latent in the system without anyone noticing for years and then when the backup fails the system will still go down.
For this reason we make sure to instrument each redundant connection so when any failure happens we instantly know, get a notification, and can schedule a repair for the next maintenance day - all while Prufrock keeps mining. Thatโs what lets these machines keep mining continuously with zero people in the tunnel.
Weโre hiring electrical engineers. Come help us keep pushing this further. Link to apply in the comments below ๐

"This was absolutely amazing," says Orri Ragnar. Another driver just turns right in front of us," he told @visir_is
โit hadn't been for their @Teslaโs autopilot responses, things would have been worseโ
Vote FOR @elonmusk. The award is only achieved IF he hits exceptionally ambitious market-cap and operational milestonesโif he falls short, he gets nothing. If he succeeds, shareholders will win big through unprecedented value creation, and he will earn added voting rights to continue driving @Tesla's long-term vision.
Last dayย to vote your Tesla shares ahead of our Annual Meeting โ deadline is 10:59pm CT tonight
Vote โFORโ Proposals 1, 3 and 4

ALS is a neurodegenerative disease that gradually and relentlessly takes away bodily functions, such as the ability to speak.
With Neuralink, we aim to restore the voices of those who have lost them.
