    Oh and how have I not said this YES PLEASE CAN WE SEE THAT SPREADSHEET?? I think I attempted that same spreadsheet last time I put a KSP1 tech tree overhaul together and it is not easy. 

    Ah, Yes. The Negotiator | Know Your Meme

    Kind of weird to me that Eve isn't considered a "target" in progression until tier 4, that should be a very easy early target for probes at tier 2. Gilly is very easy to reach as well. Hopefully science experiments aren't locked by tier to prevent exploiting those low delta-V costs, that would be really disappointing.

    I thought that meant that you just needed a durable enough experiment to survive the local conditions, could also just be talking about a crewed flight which would definitely belong in late progression (to this day I've never actually returned a Kerbal from Eve's surface, not for lack of trying :()

  2. The only thing that comes to mind for a quick ending to an interstellar species would be a supernova, that is of course assuming that said species as only spread to it's local neighbourhood. An old star explodes and fries everything in a couple hundred lightyears. Even then some of the further colonies or bases will probably survive if they've spread out far enough but any civilization they once had has been destroyed. A slower ending would be a galactic collision, which would take place over billions of years, though beings that evolved to somehow live that long would have to prepare for it. Though it would probably just disperse the 'species' , not that were looking at anything biological (or conceivable) at this point, they may not even care or notice.

    How expensive will it be to fly an expendable SuperHeavy and a reusable StarShip? Say they don't crack hot-staging, the refurbishment turns out to be uneconomic or whatever. This is an inverse of the usual paradigm, but I'm throwing ideas around.

    Come to think of that, what is the price of a fully expended vehicle? I assume it's cheaper than a typical rocket of this size but probably not economical to have without it being reusable, especially with all the engines.

    Probably a greater internal volume to use, and perhaps lower reentry thermal loading in the forward section due to the stubbier shape?

    I believe elon has said that a flater nose is actually better for reentry but wanted to make it pointy. Classic Elon :P

    Good to know, hoping that last test goes well. A spring launch would be nice. I'm sure the Astronauts are ready to go up for their mission.

    I'm sure they'll both have 'important personal matters' if that thing becomes clear to fly and promptly retire afterwards ; )

    ...a bit off-topic the recent events at SpaceX...

    I would slap some wings to SH and weld a proper cone on top (Blast cone hehe) and land SH like a glider...

    Hoverslam is nice and all, mechazilla is great but i think landing like a plane would be more logical.

    Or is this tube too bottom heavy to glide at all? 

    It's just too clunky to make practical I think. It's been proposed many times and since the 60s for even the Saturn V. Just too heavy and too light lift even with wings.

    FTS on SS may have been incomplete.  I'm wonder if something like integrating an off the shelf (or custom probably) black box on the second stage could over time make situations like this, and Rocket Labs recent situation, less mysterious.  Of course they'd need to be very tough and recovered.

    Not sure how to feel about that, on the one hand the ship was effectively destroyed and even surviving chunks would burn up shortly afterwards. On the other hand this could be grounds for another months long investigation which wouldn't be good for the program given previous delays.

    Also: It's possible more pieces survived because the fuel tanks were nearly empty, without the extra help only the installed system would be tasked with the termination (B9 clearly still had a lot of fuel inside it's tanks when it came apart)

    It doesn't look quite as zippy as SLS, but then I realise SH's carrying a lot more and I give it some slack.

    Those shockwaves look immense.

    RGV Aerial's view of the launch pad afterwards:

    Looks mostly intact, if a little charred. They'll probably have to reenforce the tank farm in between flights though, I don't think that unused tank is gonna take another flight.

    The plume is seen as weird because it looks like it just appears out of nowhere and then is followed by FTS activation. It could be the camera acting strange though.

    It would be very bad if the sea level engines got shutoff because they are the only engines on the ship with gimbal.

    Is it possible it's a tank rupture and not a rocket plume? Seemed too large to be from the engines.

    Turns out it is harder than I thought to google a quick answer to the terminal velocity of an object dropped into the ocean as it hits the bottom.

    Anyone know how fast the gridfins were going on sea-floor impact?

    Depends on how they flow through the water. When a ship sinks they usually travel between 30 to 60 MPH on descent and I'd assume the grid fins wouldn't have fallen much faster after ocean impact. Not sure how much would be left though, rewatched the footage and it seems the boosters destruction was pretty much total (even more damaging then last time) which is good for public safety regarding the FTS but not good if you want to hunt for rocket parts. That and the fact the impact with the water would total them even more. But assuming that one survived the breaking up of B9 and the impact the surface I'd wager it's possible that it's going to be detectable if one had the time and money too look for them. That being said it would be better to consider looking for the B7 gridfins instead because it was slightly less explosive and more of a big 'pop'.
