  • The Saturn V could lift 141t to LEO…once. Also it’ll be at least another 5 years before we reach a stable max power version of Starship.

    For example the Falcon 9 v1.0 first flew in 2010 and the current Block 5 version first flew in 2018 with more than double the LEO capacity when fully expendable.

    If they configure Starship as fully expendable it can lift 250t to LEO (per SpaceX, so grain of salt there to be fair).

    As for the shuttle, I love it to bits and I’m sad it had to be grounded. It was refurbishable but not really reusable and the massive liquid fuel tank was discarded in each flight.



  • Disclaimer: Fuck Elon Musk and all the shady shit he’s been pulling off.

    That said, this is one of the most impressive things I’ve ever seen in terms of the potential it holds to shape the future.

    Up until 5 short years ago we had:

    • No main booster recovery
    • No rocket nearly as powerful as this one
    • No successful flight of a full-flow stage engine
    • Nobody even considering the catch with chopsticks thing
    • No private company testing super heavy lift vehicles (BO is about to enter the chat as well)
    • No push for reusability at all

    This was all built on top of the incredible engineering of NASA, but this one launch today has all of the above ticked.

    This is like making the first aeroplane that’s able to land and be flown again. SpaceX uses this example as well, like, imagine how expensive any plane ticket would have to be if you had to build a brand new A380 every single time people wanted to fly and then crashing it into the sea.

    Going to space is EXPENSIVE. If this program succeeds it will both massively reduce the cost to space and spin off hundreds of companies looking to do the same in various ways.

    Look at any new rocket currently in development, they all include some level of reusability in the design and that’s all thanks to the incredible engineers of SpaceX paving the way, first with Falcon 9 and now with Starship.

    We’re talking industrial revolution levels of progress and new frontiers in our lifetimes, which is very, very exciting.










  • The ISS is visible from any single point you’re standing on for up to about a minute when passing directly overhead and then the next orbit isn’t close enough for you to see.

    Some comm and weather sats here and there but really nothing crazy. It was even fun to have individual shots with a streak on it cause it was a relatively rare occasion.

    Now there’s just no hiding from it. Yes, the process of stacking images averages out the streaks in the final image, but for the average person with a wide lens taking a milky way shot during summer camping it’s basically impossible to not have like 5 streaks on it.


  • I started doing amateur astrophotography last year with a camera, lens and startracker.

    The way it works is you take dozens or hundreds of photos of the same thing, then combine them into one final image, a process called “stacking”.

    To gather faint light, each photo is a long exposure gathering light for 30 - 120 seconds.

    I have therefore taken over 20.000 long exposure shots of the night sky, pointing at different things, using wider and narrower lenses and NOT ONE SINGLE CLICK came without a Starlink streaking across the frame.
