Brotoro Posted March 11, 2018 Share Posted March 11, 2018 That core stage is coming in at a really steep angle...and looked to be going much slower than I would have expected, but I assume that the video is slowed down. Quote Link to comment Share on other sites More sharing options...

Yeah, the video is slowed down. It took 40 frames to drop 125 pixels, diagonally. The stage height appears to be 54 pixels, again diagonally (thanks Pythagoras). The core is the same height as a standard Falcon 9, or 47.7 meters, and YouTube plays at 24 frames per second, so this says it fell 111 meters in 1.7 seconds, for an average observed speed of 65 m/s or 145 mph. Elon said that the core hit the water at 300 mph so it's probably at half speed. If you go frame by frame you can see that every other frame is interpolated. But yeah, very very steep. Surprisingly so. 6 hours ago, CatastrophicFailure said: Possibly relevant information: *sniffles in a manly, I’m-not-crying-you’re-crying way* Also: BulgariaSat plz. **sniff** Quote Link to comment Share on other sites More sharing options...
sh1pman Posted March 11, 2018 Share Posted March 11, 2018 (edited) (the sound is horrible) Mars colonization summary from Elon himself: "Difficult, dangerous, good chance you'll die" Short BFR flights in the first half of 2019. Full reusability will reduce the cost to space by an order of magnitude. BFR cost per flight less than $5M Edited March 12, 2018 by sh1pman Quote Link to comment Share on other sites More sharing options...
tater Posted March 11, 2018 Share Posted March 11, 2018 BFS grasshopper flights first half of next year. (note that grasshopper was not a real F9, so I'd say the same of this testbed) Quote Link to comment Share on other sites More sharing options...

NSEP Posted March 11, 2018 Share Posted March 11, 2018 Cool, BFR grasshopper has already been delayed from late 2018 to early 2019, way to go Elon ok Elon, its was just a joke! I don't want to be the next cowboy on the BFR grasshopper, PLEASE! 41 minutes ago, tater said: BFS grasshopper flights first half of next year.

If so, i can't wait to see the pretty pictures of the BFR under construction! Quote Link to comment Share on other sites More sharing options...
tater Posted March 11, 2018 Share Posted March 11, 2018 At the ITS talk they had already built a 12m tank. I expect they are working on similar aspects of BFS. The vertical hops version is a sort of boilerplate, after all. Quote Link to comment Share on other sites More sharing options...

Only if you get the secret chocolate bar with the tickets to the chocolate factory. I thought that Boca Chica was going to be the first launch site for BFS, I don't think they are ready, can 39A accomodate something twice as big as a Saturn 5?

Powered by frobscottle (cos that stuff always goes down - although sinking bubbles would probably mess up tank pressurisation something fierce) and LOX? And on a different note, a friend sent me a link to this video of the Falcon Heavy launch. Slightly old news I know but I thought it was a nice video that folks on here might appreciate. Also , keep an eye out for the core booster footage at 1m11. And that dual booster landing never gets old...

StrandedonEarth Posted March 11, 2018 Share Posted March 11, 2018 Interesting stuff on the livestream, but it's painful watching Elon talk live, with the ums, uhs, and pauses for deep thought ("buffering, please wait"). I'd rather just read a transcript.... 15 minutes ago, PB666 said: I thought that Boca Chica was going to be the first launch site for BFS, BFS/G test flights will probably be at the same site in Texas where they tested the F9G and F9R-Dev (which self-destructed while nitpicking over a sensor reading). 1 hour ago, sh1pman said: Mars colonization summary from Elon himself: "Difficult, dangerous, good chance you'll die" I liked how Elon chuckled when he said that, while the audience was, uh, dead silent during and after that.

Mad Rocket Scientist Posted March 11, 2018 Share Posted March 11, 2018 (edited) Looks like the Q&A is down, hopefully they'll reupload an edit version with good audio. I stole this transcript from FutureMartian97 on reddit. (Edit: removed link just in case, it was on r/spacex) "How long will this take?" - I'm optimistic but i'm trying to re-calibrate, but we are building the first ship right now, and I think we can start doing the first up and down flights in the first half of next year. If rapid re usability works out we are confident we can get the cost of a BFR launch down to 5 or 6 million dollars. "How do you manage your time?" - At SpaceX 80-90% of my time is focused on engineering and Gwynne Shotwell handles the business side of things. And that video is the result of the great people at SpaceX. "Who are you inspired by" - Kanye West obviously. laughter "So why do all of these things?" - Well I thought to myself why are we not making progress in space? Where are the bases on the moon and the space hotels as promised? I looked at NASA's website and it never says when were going to Mars. There will also be no will to go to Mars if there is no way to get there. "Why is no one else doing these things?" - What's your pain threshold? "What was your biggest failure and how did it change you?" - Tons of failures along the way. For SpaceX, the first 3 Falcon 1 launches failed. Maybe if I was able to higher a better chief rocket designer, then maybe we would've had less than 3 failures. "How do you prioritize all your companies?" - For business stuff almost all time is dedicated to SpaceX and Tesla. For non business stuff it's my kids. Boring Company started as a joke because it sounded funny. "Why are you so concerned about AI?" - The biggest issue with civil AI experts is that they think they know more than they really do. Very close to the cutting edge of AI, and it scares the hell out of me. I think the dangers of AI are way worse than nukes. "What issues should the next generation be solving?" - Making life multi-planetary. Need to make sure there is a seed to keep humanity going in case of another dark age, possibly caused by a third World War. Sustainable energy is also really important. "What do you hope the world will look like when children born today are your age?" - Mostly transferred to sustainable energy, base on the Moon and Mars. Anyone can go to Mars or anywhere in the Solar System. Achieve symbiosis with AI. "What can you tell us about Starlink" - Internet for people with no internet, good for sparsely and moderately populated areas. Will be good to fund BFR. "What kind of government for the first Martian colony? Your position?" - Emperor or God Emperor? Really most likely direct democracy. Everyone votes on every issue. Keep laws short. If the word count on a law exceeds Lord of the Rings then it's to long and suspicious. Edited March 12, 2018 by Mad Rocket Scientist Quote Link to comment Share on other sites More sharing options...

Twice the thrust, but not quite so wide. Saturn V was 10 meters across at its base, without fins or engine shrouds; BFR is 9 meters. 2 hours ago, sh1pman said: I’ll take symbiosis if another option is extinction.
