  • Title: SpaceX Has Finally Figured Out Why Starship Exploded, And The Reason Is Utterly Embarrassing

    • SpaceX’s Starship experienced a catastrophic explosion during its seventh launch attempt, resulting from a failure in the fuel line due to vibrations.
    • The explosion occurred over the Turks and Caicos islands, leading to debris scattering over the area.
    • The fuel leak ignited two minutes after the upper stage’s engines were ignited, overwhelming the rocket’s venting capacity and compromising the engines.
    • A loss of communication with ground control occurred as the engines shut down, leading to the rocket’s self-destruction sequence.
    • The incident highlights significant operational failures, as engine shutdowns should not cause communication loss, indicating a lack of redundancy in systems.
    • SpaceX’s pre-flight checks failed to identify potential leaks, suggesting inadequate safety measures or poor execution of checks.
    • In contrast, NASA’s Saturn V rocket had a flawless launch record over its operational lifespan, showcasing superior reliability compared to Starship.
    • Starship’s design has been criticized for overestimating engine thrust capabilities, limiting its payload capacity to 40-50 tons, which is less than the Saturn V.
    • The cost per kilogram to launch with Starship is comparable to that of the Saturn V, undermining its intended economic advantages.
    • The overall failure of Starship raises concerns about the efficiency and safety of SpaceX’s approach to space exploration, contrasting sharply with historical successes in the field.

  • I’m currently on paternity leave. Took 8 weeks broken into two chunks. 5 weeks when baby was born and 3 when my wife’s 12 weeks ended. I couldn’t imagine taking a few days and diving back into work. Both my wife and I work demanding jobs - I’m not sure I’d feel the same bond with my son if I didn’t have this time… I also wouldn’t have the same appreciation for how challenging it can be to be solo with the kiddo. It’s pretty much a full time job to feed, change, and tend to the little guy. He’s fighting to be a never napper and wakes up after 20-30 mins in his bassinet. Only gets longer naps if on my lap, which pretty much locks me down in whatever chair were in when he falls asleep (I know I can’t do contact naps forever and need to get him used to falling asleep on his own).

    All that to say… I think all dad’s should get paternity leave. 5 weeks is fine. 8 is good. 12 is perfect.
