    It's hard to say how much these development vehicles would cost. Elon has said Starship development is expected to cost at least $5b.

    Long term, SpaceX have aspirational goals of $2 million per Starship launch. This is plausible providing they fly lots of flights with each Starship and booster. The Raptor engine powering Starship and Superheavy booster may be able to fly 1000 times before a major overhaul/retirement.

    Currently Falcon 9 costs about $50 million to customers (about half the nearest competitor's pricetag). The marginal cost of a reusuable Falcon 9 flight to SpaceX is about $15 million, with $10 million of that being the second stage which isn't reused. That demonstrates just how important full reusability is.

    Starship may eventually have a cost of less than $50 per kg to low earth orbit. Compared to ~$20,000 per kg to LEO for the Space Launch System (SLS) being developed by NASA which is the closest comparable system.
    The Space Shuttle was about $50,000 per kg to LEO.

    Looks like he's not doing a keynote at this time, the update's going to be a written update next weekish: tweet source. Interesting, considering how much effort they're going to to mock up the lunar lander variant...

    EDIT - Though I guess considering the state of the pandemic over there maybe necessary anyway

    13th Starlink Mission. Great success.
    100th SpaceX successful mission since 2008. :thumbup:

    In a piece of unfortunateness, it seems the upper stage from the october 6 starlink launch failed to successfully deorbit, which means there's a *huuuuuge* piece of space debris in the lower end of low earth orbit for a while. With a perigee of 238km it's going to take a while to deorbit (a year? I havent run a rarefied gas dynamics simulation in about 18 years, maybe I should pull some old code out and simulate it :p)

    EDIT - I cant remember another falcon 9 upper stage *ever* failing to deorbit when it was supposed to, either. Anyone aware of another?

    aaaaaand immediately everyone starts up with test failure, SpaceX don't know what they are doing blablabla.... just because of some sparks!

    I can understand why companies hide this stuff from the idiotic public.

    Everyone seems to think firing up 3 Raptor engines is like starting your car lol when its more like setting your car on fire full of TNT.

    Most people are saying it's simply the power of the 3 x engines at once digging in to the concrete pad, you can see the debris is lit from the exhaust and ceases to glow as soon as the engines stop.

    I think there might have been an issue with youtube. I was experiencing the same on 3 other videos. Seems to be working now though.

    Elon confirms a design issue for SN8 needs to be addressed.
