Also the falcon 9 upper stage weight four ton or 10 times the weight of the satellite. It don't perform so well on small payloads going fast because if only two stages with an heavy second stage. An kick stage would make sense, they went for an larger fuel tank on satellite and let it handle it itself. Quote Link to comment Share on other sites More sharing options...
tater Posted April 14, 2018 Share Posted April 14, 2018 People saying the stretch is less than originally guesstimated. Someone observed that video aspect ratio was wrong. Quote Link to comment Share on other sites More sharing options...

Wouldn't need to last a day; it's just one burn out of LEO. 3 hours ago, magnemoe said: Also the falcon 9 upper stage weight four ton or 10 times the weight of the satellite.

Block 4 Falcon 9 would have no trouble sending 370 kg far beyond Mars, even with ASDS recovery. The destination orbit is about phase timing for a precise lunar slingshot and nothing else.

Things have to be absolute perfect for the maneuver, it's like lagrange points I think. Quote Link to comment Share on other sites More sharing options...

CatastrophicFailure Posted April 15, 2018 Share Posted April 15, 2018 Interesting tweets this morning: in no particular order, cuz it's morning... TESS's booster will fly again on the next CRS mission Spoiler Tomorrow's weather still looking 80% good: Spoiler BFTent:absolutely not a miniature Spoiler TESS's upper stage will not be de-orbited. Spoiler Fairing is equipped for recovery and will land in the ocean, but no Steve-O: Spoiler Apparently a droneship landing is actually easier on the rocket: Spoiler And since this is the last Block 4, probably the last all white booster: Spoiler Quote Link to comment Share on other sites More sharing options...

CatastrophicFailure Posted April 15, 2018 Share Posted April 15, 2018 I wonder if they're considering giving up on the idea entirely? Maybe modifying the fairing to be a bit more waterproof and soft-landing on the water is starting to make more sense? Quote Link to comment Share on other sites More sharing options...
NSEP Posted April 15, 2018 Share Posted April 15, 2018 When im home, i will have a look at the aspect ratio and see if it really changed height. If it the BFR changed height, its big news, if it didn't, its a big disappointment. Quote Link to comment Share on other sites More sharing options...
NSEP Posted April 15, 2018 Share Posted April 15, 2018 (edited) I don't want to dissapoint you guys, but the BFR didn't get significantly taller. There is a video on YouTube where the aspect ratio of the footage is scaled the way it should be, as you can see here. I then overlayed an image of the IAC 2017 BFR, and its about the same size. So, the BFR us the same as it was previously, when it comes to sizing. EDIT: wait what? Nope? it did changed size? It IS a little bigger. Not astronomically bigger as the original, but a little bit.

The general consensus on Reddit is that it has been stretched but the new BFR video was a lazy animation job (showing the rocket at the same scale as the 2016 ITS). Elon said it has been stretched on Twitter, and we know it's still 9 meters due to the tooling, which appears to be 9 meters. Also, better images have been released: http://www.humanmars.net/2018/04/spacex-big-falcon-rocket-launch-images.html Quote Link to comment Share on other sites More sharing options...

CatastrophicFailure Posted April 15, 2018 Share Posted April 15, 2018 And here I thought they had completely given up on that. Does he mean TESS? It would have a craptonne of extra weight capacity, but they just said they aren’t returning that one at all. Quote Link to comment Share on other sites More sharing options...

Ultimate Steve Posted April 15, 2018 Share Posted April 15, 2018 WHAT THE - woah, this is unexpected. We've got a giant bouncy castle and giant party balloons. What's next, giant streamers? Giant bows? Giant cake? Actually, now that I think about it, Falcons are just really big upside-down candles... Quote Link to comment Share on other sites More sharing options...

Maybe it’s mostly for data collection toward that end? They mentioned the same thing in the buildup to Falcon Heavy, sounds like they’re gonna try a ballute.

Ultimate Steve Posted April 16, 2018 Share Posted April 16, 2018 Actually, this sort of reminds me of something I did in Minecraft a long time ago... Long story short, it was an extensive survival that allowed spaceflight through cheats. The rocket was fully reusable, and the second stage deployed a parafoil and landed on a large pad made of slime blocks, making it effectively a bouncy castle.

CatastrophicFailure Posted April 16, 2018 Share Posted April 16, 2018 Quote And then land on a bouncy house Because that's been working so well with the fairings... Altho... didn't he mention something similar back before FH? I know he's mentioned the bouncy house before, when it wasn't related to fairings...
