    Scott Manley pointed out, and I hadnt considered it but it's obvious when you do, that separating dragon and its trunk from the lower stages at max q leaves you with a blunt body object with absolutely no aerodynamic streaming whilst it's transsonic. So probably they assess the rocket's going to RUD whether they want it to or not.

    SpaceX plan 24 launches more of these SpaceX Starlink clusters of 60 Internet relay network sats.. in 1 year!

    For the first time ever this is the 4th flight to space and back for this Falcon 9 first stage rocket, they are aiming for 10 launches per vehicle lifetime operation.
    Also world first for payload fairing re-flight use after both halves being used and recovered from a previous launch.

    Sounds like the in flight abort test has slipped to february

    EDIT - Or possibly not, there's a few reports the guy in the broadcast yesterday misspoke, and it'll still be before the end of this month. Some idle speculation on twitter he meant that DM2's expected to be in february, which would be much better news if so

    EDIT 2 - New official word is NET jan 4

    Starliner's test flight has run into Issues (TM) for anyone who's not watching... seems like it ended up put it in a less than nominal orbit. Currently in a stable orbit with solar panels deployed, but at time of writing they're not saying much else, might end up being a mission scrub maybe

    EDIT - Yeah basically a mission scrub, they're just going to deorbit and test reentry with no ISS docking

    I watched for about 20 minutes and they didnt have any onboard footage or stats on screen.
    Lackluster launch. They have a lot to learn from spacex marketing team ....

    4 years ago today, SpaceX made history - now it already feels like routine.

    4th launch and landing for that first stage rocket, SpaceX are capable of doing their own missions on the cheap. :thumbup:
    Up and back in just over 8 minutes, https://twitter.com/i/status/1214373450371891200

    The 48th successful first stage landing for SpaceX.

    So, something like $1B saved so far? At about $30M for a new first stage, and assuming $10M average overhaul cost. That cost will probably drop with Block 5 since they're designed to require less inter-flight maintenance.

    A reminder for anyone who hasnt seen, the in flight abort test is scheduled for 11pm aest this saturday night (midnight AEDT)... should be pretty spectacular given they're flying a fully fuelled f9 (albeit missing its upper stage merlin)

    thats also 30 mill on a rocket that has an amazing $/kg of payload. The Merlin engine is a work of art in that regard.

    edit: https://everydayastronaut.com/raptor-engine/ 2/3 the way down there is a nice table

    Could possibly be pushed back to tomorrow, very windy at the cape apparently.

    still got 13hrs to go and its a 4hr launch window. I don’t think they are super concerned about upper level winds anyway since its an abort test?
