    This launch is of Progress MS-10 which was launched atop a Soyuz-FG rocket out of Kazakhstan in November 2018.
    The "core stage re-entry" part is the rocket falling back into the atmosphere and simply burning up on re-entry, such a waste these days..

    There's video footage taken from Gemini 7 of one of the early Polaris ballistic missile test launches, looks bloody cool as. It's in one of the episodes of When We Left Earth: The NASA Missions, I couldnt find it on youtube

    How about building your own model falcon heavy rocket, with it's own custom built flight hardware and software:



    Now he's working on automated rocket landing, fine tuning his hardware and software coding:

    Skynets unleashed.

    I for one welcome our new low orbit, low ping, ion powered overloards.

    SpaceX successfully launched and deployed all 60 Starlink broadband Internet relay satellites in one Falcon 9 launch, heaviest payload launch ever.
    It was this particular first-stage rocket's 3rd launch and land!

    Was an awesome launch, watched the deployment also. Man those grid fins took a pounding!

    Yeah, though I wonder how much of it looking like more plasma than usual was just cause it was so utterly pitch dark it was more apparent. It was apparently one of their highest energy reentries though. *shrugs*.

    Next two launches are radarsat constellation for canada, and then towards the end of june the one we've all been waiting for, falcon heavy launching the STP-2 mission for the USAF, a whole cluster of mid and small sized experimental satellites. I'm hoping they dont cut the video feed on that one, that should be quite a spectacular deployment

    The everyday astronaut feed had a kerbal sim of the way the microlink sats deployed. About 1;40 to 1;50 along the feed.

    Im blown away, i had no idea this was the way it worked
    Great launch. And now i understand the comments about the grid fins taking a pounding. I wish there was more coverage from that event :)

    They didn't bother with a boost-back burn this time (first time ever?), just turned back down again for a re-entry burn which probably meant more speed/friction that usual? (as a test?)
    Those grid fins are some of the largest single piece cast & cut titanium objects in the world for a reason I guess...

    They dont usually do a boostback for at-sea landings

    This is not typical, they have boosted back for most barge landings before, probably to reduce the downrange recovery distance offshore.

    Typical Falcon 9 launch profile:

    Didn't have the fuel to make it back with a boost back burn.

    Heavy payload.

    This was close to max re-entry velocity as well, hence cool plasma.

    The train of Starlink satellites passing over Leiden, the Netherlands, about 22.5 hours after launch.

    Yeah, crazy good stuff. Although I suspect the next-gen starlink sats will have some nano-black coating so the astro-photogs will be happy. They seem to have some valid concerns given the sheer numbers of the sats that will be going up there.
