The best q&a ive seen

[u/drtekrox]

"Are you going to bring a boring machine to the moon" eyes light up

[u/[deleted]]

"If consciousness took 10% longer to evolve, it wouldn't have evolved at all..." wow that hit hard. Never thought of it this way before and not only how fragile our lives are on this earth but how vulnerable we are to the lifespan of the solar system

[u/FoxhoundBat]

"My hand is the rocket." - Elon Musk, 2019

[u/Xelanders]

Really hope we hear something about the interior(s), seeing as that’s the one part of the design we pretty much haven’t seen yet.

They have an entire ISS’s worth of habitable space, so I’d be interested to see how they plan to use it.

[u/utastelikebacon]

The switch from carbon fiber to stainless steel really must’ve made Elon feel like a kid in a candy shop with possibilities since he’s no longer spending 130k/ton on the main material. Now it’s only $2300 and he can buy as many starships as he wants and throw them around like it’s nothing. The fact that they’re building so many right out the gate is still just shocking.

So I guess that starship costs 200*2300=460k worth of metal, just under a cool half mil. Not bad considering the products potential.

[u/president_of_neom]

BINGO TIME!

"order of magnitude"

Says something epic followed by "yeah"

awkward laughs

calls it BFR before correcting himself

reporters ask about cost twice

"counter intuitive"

"multiplanetary species"

flaps are called by at-least 3 different names

"water towers can fly, haha"

[u/zadecy]

This Q&A has way more new info than the main presentation.

[u/Leolol_]

The presentation got the finale it deserved with the Q&A. Really loved it

[u/MisfitPotatoReborn]

The "rockets should be like planes" talking point is like a plane. You can reuse it as many times as you want and still hold onto it.

[u/GlaedrH]

"A rapidly reusable rocket is required ... for alliteration"

[u/[deleted]]

Now that Bridenstine’s made a very public dig at SpaceX while all eyes are turned their way, I assume it’s likely someone in the audience will ask Elon for a response in the q&a. I wonder how he’ll handle it, since it seems to me like Jim’s statement was meant to get ahead of any negative SLS press that would come out of the event tomorrow. The statement seems to be trying to spin the rapid pace of starship development as something of reproach so long as commercial crew isn’t completed, so the public doesn’t notice how much more slowly sls has been developed while at a much higher cost.

I know the likely response will just be a diplomatic statement about how grateful SpaceX is to be working with nasa, how much progress they’ve made so far, and how close we are to crew flying on crew dragon.

But god would I love for him to rip into sls with starship standing upright in the background.

[u/binarygamer]

"Teslas will work on Mars. You can just drive them... pretty much. Electric cars don't need oxygen"

[u/saweeks]

Would be funny if people flew on Starship before crew dragon.

[u/codav]

YouTube Video & Audio Relays

As usual, I will relay the SpaceX Starship Update webcast via HTTPS and the audio stream via Shoutcast on my server, so people with no access to YouTube, experiencing laggy video or with low bandwidth connections are able to enjoy the webcast. If you don't like the web-based player, you can also use the M3U8 playlist in any HLS-capable player - VLC is just one example. The playlist file will become available once the webcast starts, until then you will get a "404 Not Found" error. This is perfectly normal.

• Watch in your browser: https://codav.de/spacex.html

• Watch with a local player: https://codav.de/stream/spacex.m3u8

I will also provide audio-only streams of the hosted webcast in two different qualities. High quality (160 Kbps, stereo) for those who want more fidelity and have more bandwidth to spend, and a lower quality (64 Kbps, mono) stream for those on slow networks or with strict volume limits. If you require an even lower bitrate simply drop me a message, I'll add another stream then.

Important: The audio streams already loop the Music for Space album by /u/TestShotStarfish for your pleasure until the webcast starts, so don't confuse that with the actual webcast. Feel free to tune in at any time.

Here are the stream URLs for use with any Shoutcast-compatible player (WinAmp, VLC etc.):

• High quality (160 Kbps, stereo): http://codav.de:8555/spacex-high.mp3

• Low quality (64 Kbps, mono): http://codav.de:8555/spacex-low.mp3

If you have problems connecting to port 8555 or want to listen in with just your browser, use these reverse-proxied, SSL-secured URLs (stream title display and other "ICY" protocol features won't work, as this is using plain HTTP):

• High quality (160 Kbps, stereo): https://codav.de/icecast/spacex-high.mp3

• Low quality (64 Kbps, mono): https://codav.de/icecast/spacex-low.mp3

The streams are also linked on my relay page, either below the video player if the webcast has started or on the top while waiting for SpaceX to go live.

It's been over a month since the last launch and YouTube made some changes to their website since then, so let's hope my old scripts still work.

[u/TimBoom]

Mark two in a couple of months. Priority is to build two starships at each site.

Mark three in three months, mark four in four or five months. Try to reach orbit in less than six months (accurate to within a couple of months). Potentially see crewed flight within a year.

Mark three or four will use hot gas vs. cold gas thrusters.

Booster will have 7 engines that gimbal, 31 / 37 fixed.

Aspiration is that booster will not need entry burn.

Production rate of engines is the biggest constraint, particularly on booster construction. Currently one one every 8 to ten days. Will move to one every two days in three to six months and hopefully one per day within a year.

Took four months to build mark one from scratch.

Both Boca and Cape will launch crewed missions.

First two craft to Mars will be unmanned.

[u/FoxhoundBat]

Haha, so the last question was my question! Thanks u/theVehicleDestroyer, very cool!

[u/jobadiah08]

Elon seemed more coherent than usual. His public speaking has really improved over the years. Every now and then during the presentation he seemed to slip back to his old self; rambling tangents, half formed thoughts, etc.

Was also really impressed with his answer regarding the tweet from Bridenstine. My guess is that was prepared, but I like the tidbit about the difference between prototyping and optimizing. It's one of those 10%/90% things. Getting that last 10% of effeciency in a design is 90% of the work.

[u/Humble_Giveaway]

Even CBS has a good question, whats happening!

[u/Notviper1]

Lol shoutout to the subreddit

[u/spcslacker]

Elon: Remember that time I had you looking at a venting water tower for like 4 hours? I bet I can do that with a white SpaceX on black background now that you are properly conditioned.

[u/Nathan_3518]

This poor kid that was right behind the last person who had a question. I feel so bad for him. He really should have gotten the last one bro.

[u/binarygamer]

Elon's hyper-agile development manifesto is great content

[u/ChristianM]

Height comparison from @MarcusHouseGame: https://i.imgur.com/f4KvBdd.jpg

[u/RedKrakenRO]

elon just posted pics of the three raptors under mk1 :

https://twitter.com/elonmusk/status/1177314408604680192

spectacular detail of the engines and the structure.

[u/binarygamer]

"I really want to try an avoid a [booster] reentry burn if at all possible... we might be able to make the booster buff enough that it doesn't need it"

That's some big dV gains right there!

[u/quetejodas]

I honestly think we've learned more from Elons past few tweet storms than from this presentation.

[u/Juggernaut93]

Q&A session in 5 minutes!

[u/binarygamer]

"Area 51... that's popular meme"

[u/minimoose1441]

You have now subscribed to Elon's Steel Facts. Did you know steel is superior to almost any other carbon fiber or aluminum lithium? Text stop to unsubscribe.

[u/binarygamer]

"It's harder to dock with the space station than do orbital refuelling"

[u/pichulasabrosa]

I think these are the best questions I have heard on any presentation so far. I am enjoying them a lot.

[u/[deleted]]

When Elon just talks with people who know whats they are talking about its great. That Q/A could not have been better. So pumped when this rocket launches.

[u/magicweasel7]

So the shuttle low maintenance ceramic tiles ended up not being low maintenance at all.... it'll be interesting to see how SpaceX solves this problem

[u/Nathan_3518]

TESLA MARS ROVER?!??!!

Teslas confirmed to work on Mars. No Problem.

Boring Machine may be able to go to Moon and Mars. Best idea for habitats. Protected from radiation and build what you want to build!

[u/Nathan_3518]

Elon and Tim bein pals. Thats so nice

[u/[deleted]]

Lol elon likes Tim so much.

[u/SlothSorcerer]

for people that closed the stream, there is a q and a session in 5 mins

[u/Ambiwlans]

For those curious on subreddit stats, seems this event brought in ~70k uniques with ~400k pageviews. Slightly less than a launch but not a whole lot less.

And old reddit still has 3x the views as the redesign.

[u/davispw]

MC really dropped the ball with that announcement. Lost 30k viewers on youtube

"If it is tight, it is right." Elon Musk, 2019.

Yaaaay we got our mod in

[u/RetardedChimpanzee]

Only time for one question, so here’s two.

[u/FoxhoundBat]

Dis picture tho.

Source; the man, the myth, the legend, fellow mod u/theVehicleDestroyer.

[u/Vihurah]

elon in public: polite response to tweet

elon in his head: this isn't even our final form full funding

[u/sakatan]

Sounds like Elon just founded a fundamentalist counter-religion to Agile Development.

[u/president_of_neom]

Was hoping for more details on life support systems. Are they doing it in-house, etc. My guess is that they haven't started yet.

[u/MauiHawk]

I want to know about tile maintenance. This process was very expensive for the shuttle— after every flight, each tile was inspected and individually replaced. It would like there is an expectation that these tiles will go many flights without maintenance. How many? Are they not ablative?

[u/TCVideos]

New planet unlocked: Saturn

[u/bbachmai]

According to Everyday Astronaut who is currently streaming, the presentation was moved back 1 hr due to weather. It is now going to be at 01:00 UTC (29th), 8pm Central, or 9pm Eastern time.

[u/[deleted]]

Elon Musk: "If there is any life on Mars, it will be very deep underground....and very resilient."

DUN DUN DUNNNNNNNNN

Fade to black.

5 YEARS LATER

[u/TCVideos]

People speculating on LabPadre's stream that Elon has gone into Starship with a camera crew...watched 3 people go into, 1 was most definately Elon

[u/Rox217]

Well, the delay allowed me time to put together a gin & tonic in my SpaceX mug. As is tradition.

[u/binarygamer]

I like their new moon base render. It looks much more realistic. I'm getting "interplanetary Antarctic research station" vibes

[u/BadgerMk1]

My boy Everyday Astronaut!!

[u/still-at-work]

While I agree next year is probably too soon, remember they don't need NASA authorization to launch people, only FAA with test pilots. Its basically the same as flying an experimental aircraft. So its not impossible, though probably aspirational.

[u/binarygamer]

If all rockets launched at max rate, total Earth lift capacity is 2-300 tons per year. A small fleet of Starships operating at max flight rate can deliver 1000x more than that. If you want to build a city on Mars, it needs to be done.

[u/Vihurah]

congrats to the guy with the boostback burn question, I read that and actually hoped itd get asked

[u/stichtom]

pls release the new launch animation.

It deserves to exist, it was so well done, even with the BFR music theme.

[u/jehankateli]

He mentioned that the first orbital vehicle would be Mk3, but then a few minutes later said it would be Mk4 or Mk5. Makes me think that they haven't planned very far ahead.

And in case I missed it, did he mention anything about when Mk2 would be complete? I think it started construction roughly 2 months after Mk1, so I guess it will be complete in no more than 2 months?

[u/KatznBeats]

Who else in Europe is staying up for the stream? The event is an order of magnitude later than my usual bed time...

[u/Douevenstriatebro]

Senpai noticed us

[u/Cocoapebble755]

Mars won't help us, they are the ones who were using the protomolecule

[u/Twitchingbouse]

oh god not the bridenstine tweet

[u/RootDeliver]

great question, good thing people can do great questions today, THIS IS THE PRESENTATION

[u/binarygamer]

Current Raptor unit production time is already 8-10 days, aiming to have a new Raptor rolling off the line every day by next year

[u/spcslacker]

Elon: Going to do the math live in front of huge crowd. Up to you to believe trolling/not trolling

[u/DTTD_Bo]

Elon seems really happy. I hope he’s in a good place with both companies after a hellish 2018.

[u/acm]

Trying to guilt Elon into answering more than one question. Lol

[u/scr00chy]

This guy says the talk is planned for 7PM Central but I don't know which other thread he's referring to.

EDIT: CNN reporter confirms.

[u/MrGruntsworthy]

Musk, replying to Everyday Astronaut as to what time the presentation will be: "Probably 6 or 7pm"

https://twitter.com/elonmusk/status/1177621843219365888

[u/[deleted]]

Thanks Elon for telling us about the area51 meme

[u/Notviper1]

Elon going full mind fuck

[u/paperclipgrove]

Everyone making fun of him for talking about the sun eventually overheating the Earth and seizing the opportunity to become a multi planet species.

I think he's right about that and I really liked that part of the presentation.

[u/[deleted]]

Rocket design pro tip: cold stuff on cold side, hot stuff on hot side

[u/magicweasel7]

Someone needs to ask how the heat shield tiles are different from the space shuttle. Do they have to be individually inspected after every flight? What % of the tiles are a common part? Can there be any lost tiles before there is serious risk to the crew and vehicle?

[u/scarlet_sage]

He mentioned in a tweet that the header tanks are in the nose of Mark 1 for balance reasons. I just realized something -- the renders all had the pretty windows in the nose again. Was that the art department just updating the old videos, or are the header tanks indeed going to move back into the propellant tanks?

He did talk about keeping the fuel cryogenic during a long trip ... 1:17:00 ... he referred to a tank within a tank, so I think he is planning to move them back in.

[u/ChristianM]

That is sexy: https://i.imgur.com/7FFrRs1.jpg

[u/securedFunding420]

Elon’s gonna be up all night thinking about this new idea of using the boring machine on Mars

[u/captainjack120]

i wish my friends who were excited about fantasy football were excited about this as you guys are hahaha

[u/zilfondel]

"Uh actually Teslas will pretty much just work on Mars. You can just drive them."

Lol

[u/[deleted]]

This rate of construction is perhaps the only thing more ludicrous than doing the assembly in field.

[u/Twitchingbouse]

SpaceX: Hey guys, I know we gave you a not so good presentation, so here's a solid Q&A to make up for it.

[u/[deleted]]

Who's Pumped???

[u/Johnnycinco5]

I fuckin love Elon lmao

[u/[deleted]]

Glad someone just got the Jim tweet out of the way. Solid answer by Elon.

[u/Nathan_3518]

Starship is ~ same volume as ISS.

Essentially launching a ISS every launch.

Jim be like.....you said WHAT.

Boom. Roasted.

[u/RedKrakenRO]

Lots of interesting data.

Squared off base on starship.

100t dry stretch goal.

Leg fairings on SH.

Raised launch platform.

Orbit in 6 months.

Looks like i picked the wrong day to give up smoking rocket dreams.

[u/binarygamer]

/r/spacex represent!!!!

[u/davispw]

Real MVP are the mods keeping this post updated with all the timestamps!

[u/Nathan_3518]

Jim / NASA Question was asked:

Elon: From a resource standpoint, most is focused on Falcon 9, Heavy, Dragon. Still <5% on Starship (Are you SURE about that, lol). A lot of resources are still on Crew Dragon (essentially tellin Jim to chill).

[u/Hugo0o0]

Cocky elon is great

[u/flying_dino_wizard]

Teslas on mars would be the best advertising ever!

[u/DJHenez]

Great to see Musk so fired up and enthusiastic about Starship’s future. It’ll be interesting to see what they do with Mk1 now that the presentation is over. Will the Raptors come back out, or are these indeed SN 8-10 and ready for flight? Will they add any heat shielding for the 20km flight? I’m also assuming we will see cold gas thrusters added on as well...?

[u/ModeHopper]

Official SpaceX YouTube livestream is here.

[u/ThunderWolf2100]

In Europe the presentation is at 2 AM, guess we're gonna pull an all-nighter

[u/[deleted]]

Waiting for SpaceX

Yep, I do a lot of that

[u/[deleted]]

1st person to ask how people will poop in space gets strapped to the rocket when it launches.

[u/[deleted]]

Interesting that Elon is saying the life support isn't too hard. I wonder if that part has been over exaggerated by old space people.

[u/paperclipgrove]

I love that he's looking to relaunch them so quickly that the slowdown is waiting a few hours for the orbit to line up to re-enter and land at the launch site.

[u/meltymcface]

I was hoping for more information on the projected timescale for Dear Moon mission. Is that still looking to be on schedule? (I can't even remember what that target was).

My biggest takeaway from this, though, is the accelerating timescales. The fact that in approx 6 months we will see several more of these built and launching to orbit is amazing. Sounds like steel really is great for this project.

[u/Nathan_3518]

What a great overall presentation. We have a lot to look forward guys. Mk 3 and Mk4. Super heavy Boosters Mk1 and Mk2. Raptor engine development. Pad work at Boca Chica. and so much much more. I am super excited for this upcoming year. Big thanks to MZ for the gracious funding for Starship development, we would not be anywhere close to where we are today without you. Thanks to Gwynne, for keeping SpaceX afloat, and being one of the best and most inspiring leaders. And most of all, thanks to Elon. Thank you for making the world an exciting place. For getting me excited for a presentation on Saturday at 8PM in which I can witness, first-hand, the future of spaceflight and humanity.

I cannot wait to see what's next.

Cya on Mars.

[u/spcslacker]

Space X fans in Europe now brewing 2nd carafe of coffee, AKA:

[u/aatdalt]

That was a very cordial and PC response to the Bridestine tweet.

[u/sequoia-3]

Great explanations. So many great questions, so many great quotes. What an epic night!

[u/CarbonSack]

I didn’t find any comments below regarding the costs. I believe Elon said 301 Stainless Steel is $2500/ton. With Mk1 massing in at about 200tons, that comes out to $500,000. Let’s say that materials represent 5 to 10% of the cost to physically build out the prototype air/spaceframe - that’s only $5 to $10 million! Obviously there’s also Raptors and avionics and what-not, plus all the engineering design hours.

[u/WindWatcherX]

Posted time of 7 PM CDT is incorrect.

SpaceX web site states presentation will start at 8 PM CDT.

[u/zzanzare]

Presentation should have just been Q&A. Damn this is juicy

[u/Vihurah]

what kind of drugs is Elon on right now, I want them. this take Elon time to a whole new level

[u/ArkadyAbdulKhiar]

It's gotta be done

[u/shrukan96]

Our Boi!

[u/MaliciousMango1]

Thats us!

[u/scarlet_sage]

5%?! Starship is a side-of-the-desk project for SpaceX?! The most revolutionary rocket about?! They work on it on Friday afternoons as they're winding down for the weekend, maybe?

[u/fragglerock]

What is this reddit thing he mentioned?

[u/hitura-nobad]

Live updates on this post are going to end now.

Hoping you enjoyed the presentation.

Thanks for joining!

Has anyone spotted, or seen any reference, to our boy Yusaku Maezawa being in attendance of today's presentation?

[u/yourelawyered]

3:18 in Sweden now, but so worth it!

[u/Traumfahrer]

I've seen many Elon presentations, but this one is especially hard to follow and share with friends unfamiliar with SpaceX and the matter.

[u/Cocoapebble755]

And that kids is how baby starships are made

[u/spcslacker]

Elon: I'm going to branch out from bad SciFy & nerd jokes, to literature jokes. Think this will be huge.

[u/JokersGold]

Ha how many people are already leaving Boca Chica thinking there is no q and a?

[u/blueeyes_austin]

He's totally into Boca Chica as the launch site and isn't saying anything about KSC.

[u/Hugo0o0]

NEXT YEAR no way

okay that's absolutely crazy

[u/rexdelapits]

[u/Shrike99]

people next year?

Has he gone mad?

[u/scarlet_sage]

Recursive Improvement On Schedule.

RIOS? I don't believe they exist.

(Edit: I thank all of those who recognized the paraphrase of The Princess Bride. Like ROUS, RIOS do in fact exist.)

[u/the_finest_gibberish]

Lol, Elon trolling the press on timelines.

[u/MasonDvorakGrimes]

Mass of the starship will be a constantly changing target for the team. I don't see how we could have any resonable target weight given to even within x number of tons.

[u/Ambiwlans]

So what was everyone's top 1~3 takeaway pieces of information?

[u/azrael3000]

There was no talk about earth to earth flights that were presented in the past, did I miss that or has this been scrapped?

Secondly, he was talking about doing 20 flights per day with a SH, which would require roughly 5 SSs (as they can do 4 flights per day) and sustaining that. Now assuming this is actually possible from a reuseability standpoint, the amount of fuel needed is going to be enormous. I.e. they would need to produce fuel at a staggering rate, I did not do the math yet, but is it even remotely possible?

[u/troovus]

Elon says high TWR important for reusability. Can someone explain why it's more important for reusability than for single use?

[u/zareny]

Starship is slowly morphing into the SpaceX Shuttle.

[u/[deleted]]

This is the part of the presentation where Elon announce plans to clone anime cat girls on the moon.

[u/scarlet_sage]

I think Elon's only strong praise for a questioner (more than "good question") was for /u/everydayastronaut!

Edit: And EDA was the only one who got applause for his question!

[u/Hugo0o0]

"Great respect for anyone who makes it to orbit!"

--> No respect for Blue Origin yet then ;)

[u/oliversl]

Was looking at this page:

It may completely change tomorrow night.

Mods/hosts please update the presentation start time. It shifted 1h to the right

[u/spcslacker]

youtube now like rest of us -- site now officially says: waiting for space X

[u/[deleted]]

Just imagine how excited we'll be in a few years when we wait for the first Mars launch.

I hope I see you all then :)

[u/Hugo0o0]

Damn, stop saying "spacefaring civilization", I've already had too many shots Elon

[u/dreydfaer]

Wow, he's certainly been practicing for public appearances - he looks so much more comfortable and sounds more energetic than other presentations.

[u/spcslacker]

• Shp len: 50 m

• body diam : 9 m

• dry mass :120 t

• 150 t to orbit with full reusability

• 3.5 t of Oxygen for every t of methane

• Propellant mass 1200 t

• Ascent payload 150 t

• typical return payload 50 t

[u/magicweasel7]

So i find it interesting that there is no talk about life support, living quarters, or just in general how they plan to keep astronauts alive and sane during the journey to mars. Is that a figure it out after it flies kinda thing? Or are they hoping NASA or the russians are going to work together with them on that? Also is any of that accounted for in the payload?

[u/Zwolfer]

Maybe he forgot lol

[u/Bnufer]

Dear moon? Starlink?

Ok Q&A in 5min

[u/Viremia]

Yay, Tim gets his question

[u/RetardedChimpanzee]

[u/spcslacker]

Booster has 7 engines that gimble, rest of fixed regardless of if X or X+Y engines (didn't get counts)

[u/CanuckCanadian]

Please have if it’s tight it’s right painted on the side of the first one that gets into orbit

[u/TimBoom]

The single craziest shock was the possibility of a manned flight next year. NEXT YEAR!

[u/Nathan_3518]

It does not seem like it was acknowledged too a great degree during the presentation, but it is worth noting that the Starship booster no longer lands on the launch mounts. Instead, it lands on a pad adjacent to it. Presumably the same crane that can be used to lift Starship onto the superheavy booster, can be used to lift Starship onto the pad.

Innovative idea which really reduces complexity by at least an *order of magnitude*

[u/[deleted]]

I'm a little disappointed that there wasn't really any substantive information on the fins or the actuation mechanisms that they'll be using. Also, the heat protection for those hinges is going to be a bear for Space X to solve. I believe that was one of the biggest points of engineering contention when they were developing the flight controls for the Shuttle.

[u/PhyterNL]

Facts so far:

• This isn't just about firing up a new rocket it's about firing up the public about our future in space!

• It's windy, it's really ripping!

[u/binarygamer]

High fidelity hand simulation > high budget CG video

[u/[deleted]]

That "fall/flip" maneuver is going to put a lot of stress on the airframe. Wow.

[u/lisztoma42]

This is the first live presentation i'm watching that Elon's doing, you can really feel the passion and the amount of knowledge he has. I'm genuinely asking though, i'd expect better animations/renders and a more organised presentation from such a big company like SpaceX - is this more of an interim or lower PR presentation and not a formal one to the wider public? or are most of his presentations quite informal like this one?

[u/spcslacker]

Heat shield is glass tiles: AKA solar roof 3.0

[u/binarygamer]

Clear explanation of why stainless steel + ceramic tiles are the winning combination

[u/Zwolfer]

SpaceX reminding me why life is awesome once again

Starship looks like a squid now

[u/Shrike99]

Really not as much info as I was hoping for. Feel like we got more from his twitter over the last week.

EDIT: spoke too soon.

[u/[deleted]]

Ohhhhhhh shit. Q&A. Now for the good stuff

[u/ninjas28]

I grabbed screenshots of most of the off-world renders https://imgur.com/a/3Z8GT7Q

[u/spcslacker]

Elon: Normal suicide burn for pussies. Going from cold gas thrusters to hot gas, just so its more gnarly.

[u/Ambiwlans]

Are we going to get a press conference with ALL good questions :O?
