/sci/ - Science & Math

Details from yesterday's presser, condensed:
>Reflying a single Block 5 within 24hrs "as early as next year"
>Block 5 exceeds all NASA requirements for crew. And meets all Air Force requirements
>Elon thinks they can get even more power out of the engines over what will debut today.
>Stage 2 has the Block 5 engine today, but will operate like a Block 4 engine on this flight.
>Titanium grid fins are now standard and what will be used going forward. Can withstand 2,000 degrees F temps.
>Fairing 2.0 is on this vehicle. It will not be recovered on this flight because the recovery boat is only in California right now.
>SpaceX will start gathering reentry data on Stage 2 over the next few upcoming flights.
>Elon confident that full reusability of the Second Stage is achievable.
>Propellant only cost between $300,000 and $400,000 per launch.
>Booster is 60 percent of cost, upper stage is 20, fairing is about 10 percent, 10 percent associated with the launch itself
>"We expect no unnecessary action taken between flights - just like an aircraft."
>Late this year, we should start seeing good reflights of 3rd and 4th times for Block 5 \ By end of next year, we should start seeing Block 5s reaching their 10th reflight.
>Human-rated rockets have to be overdesigned by 40% to meet crew safety requirements
>Merlin rocket engine thrust increased by 8 percent, to 190,000 lbf.
>Will add thermal protection systems to upper stage; the least amount of mass necessary to return the upper stage in a condition that is reusable
>South Texas launch site will be re-dedicated to BFR
>About 30-50 Block 5s are planned. Dependent on how many customers demand to launch on a new rocket
>Now charging about $50 million for a flight-proven F9 booster, rather than 60 mil
>Musk noting that China looking at reusable rockets, and says he's glad to see SpaceX is a "forcing function" to drive down launch costs.

Reusability is not cost-effective. Shuttle and Buran are the proof. Stop this nonsense at once. STOP

Can't wait for the CGI when it's finally in "space".

>Elon Musk, SpaceX’s CEO, says the upgraded Falcon 9 Block 5 launcher set to debut today is intended to be “the most reliable rocket ever built” and will be a “mainstay of SpaceX’s business” in the coming years.
It won't explode, right?

USA USA USA

>>9734663
I have a bad feeling

Let's fuckin go booooooooys

>>9734663

I'm already edging come on! I can't hold it anymore.

The YouTube link has a second link to a "map view"

Interesting..

Why?

is this a rerun?
iirc this guy was talking exact same shit yesterday

They are really dragging out this fairing recovery thing, shoulda done more non-rocket launch testing

>>9734684
It's not like he has anything new to talk about.

EXPLOSION

>"The reason that it's so hard to make an orbital rocket work is that your passing grade is 100 percent, and you can't fully and properly test an orbital rocket until it launches"
This quote as well as the ~$300k fuel cost per launch had me thinking. Would it be possible to just launch S1 (without S2/fairing/payload and just a cheap nosecone) in sort of a simulated launch and then land back at KSC? It could be a way to nail down their rapid reuse and reliability targets a lot cheaper and more quickly than through standard launch cadence.

Spacex always has a large viewing area overlooking their mission control where they always have their crowd of fanboys to cheer them on.

The place they broadcast their live feed is right next to it.

This time for sure!

Fly you glorious bastard

THAT DRONE ANGLE

HERE WE GO

>>9734675
Cum baby!

Block 5 looks great from a far.

>>9734703
if by fanboys you mean employees who work 80h a week to make the thing fly sure

>>9734714
employees who are required to be there and clap because they are still on the clock*

Here we go,
bright flash, and CGI footage.

>>9734716
Being paid to watch a rocket launch with an open bar. Seems good to me

Fairing is made of honey

So far so good.

Nice camera angles today.

They got more cameras now?

>>9734722
>>9734716
>>9734714
SpaceX understands the importance of good PR

Having a huge audience of cheering young people during their launches is great PR and makes everything they do seem cool and radical and millenial

camera is loose on the 1st stage, the RCS system firing shakes the camera

>>9734725
Yeah, the CGI department has been working hard overnight.

>>9734728
It would be funny if the camera fell off.

OH SHIT

just tuned in, how's it been

Flat or globe?

Camera ded

Looks like we just had our glitch for this mission.

why would fucking Bangladesh pay SpaceX to fuck around?

GG EZ

Very unprofessional CGI this time.

Thats how you fake it, boys

FUCK YEAH

It's actually slightly concave on the left.

What did Elon mean by this?

>>9734749
Wow, that's a stupid name, those nerds are trying too hard.

>>9734776
Also mentioned Ford. As in Henry Ford.

>>9734776
He is signaling that he is /oneofus/.

It's sooooo real

>>9734785

i cant believe elon is fucking grimes

>>9734766
I think it was more about FH never flying and when it did he started rambling about it being like shuttle.

>>9734756
>autistic retard

BO should use the funds they invest into trying to descredit /ourguy/ for some R&D instead, then maybe they would have an reuseable rocket in 30 years, too.

>>9734788
Great point.

BANGLADESH IS 1ST WORLD COUNTRY.

So, what's next for ULA and Arianespace?

STREAM GOT RAIDED BY /INT/

what the hell am I watching?

motherfucking bangladesh has it's own satelite
when poland will have it's own satelite?

who gives a shit about this famers

POO IN LOO

>this Bangladeshi propaganda film
pretty kino desu

>>9734806
*dabs*

>>9734796
He literally says there "reused rockets economically viable".

Anyways, we will see in the coming years how the Block 5 fairs. It's all about in what conditions it lands, simply landing them means nothing.

>>9734799
I do not know how Bezos is so patient. Just buy all the SpaceX engineers for fuck sake

>>9734805
>you get a satellite and you get a satellite....

what is this shit

>>9734814
Sure, but his point was that there were no reused parts and that proves it's not economically viable when it actually reused 2 boosters and both of them landed too.

>>9734815
He's actually not patient, he started puring a lot of money into BO recently and after New Glenn he will probably go straight to New Armstrong and do anything necessary to bring it to market before the BFR launches.

Even Poland doesn't have a satellite
Bangladesh > Poland

>>9734805
>polsat1

>>9734805
I feel your pain, man.

>>9734815
Bezos and Musk are both in "The Explorers Club", they're working together.

What is happening?

>>9734820
Space Shuttle also reused lots of parts, doesn't mean much if making them fit for next flight costs similar or even more than building a new one.

>>9734809
Not second hand, "flight proven"

>>9734822
Don't you guys have experience with V2 rockets

Love the purple tint on one of the two onboard cameras.

>>9734805

Polandbros, find a university that will fund a CubeSat and launch it aboard a ULA/NASA mission.

>>9734835
It's all part of the plan.

>>9734844
is there so much satelites that this is already a thing?
just wow

>>9734853

Poland may not have a satellite, but we're still in the compatriot in space club

Half expecting a Borat segment on why Bangaladesh number 1

>>9734867
I don't think that Borat is from Bangladesh.

>>9734809
It's hilarious, because Musk did the precise opposite for second-hand Teslas, to encourage people to buy new.

>>9734853
t. reddit

Did it blew up?

>>9734857
This is in a geostationary orbit, so it needs to be above the equator. "Space" is not really the problem here, but the satellites can interfere with each other in their frequencies. So yeah, you have to manage it.

>>9734872
Whatever makes you feel elitist.

Next launch when?

>>9734881

>>9734894
Well, he changed from previously launched (or whatever) to flight-tested for SpaceX to portray reused rockets in a better light. He did to opposite for the previously owned cars Tesla have on their website. Can't remember the exact words in question, though, sorry.

HE CANT KEEP GETTING AWAY WITH IT

>your average spacex fan

>>9734009
Another "new" rocket that's more of the same from one of the most dishonest companies in the history of private space travel. Seriously each launch following the Falcon family as they “revolutionize the launch industry” has been indistinguishable from the rest. Aside from the meme landings, the company’s only party trick has been to overwork and underpay its employees to reduce launch costs, all to make the mythical “full and rapid reuse” seem effective.

Perhaps the die was cast when Musk vetoed the idea of ambitious yet realistic missions like Red and Grey Dragon; he made sure the company would never be mistaken for an innovative force to anything or anybody, just ridiculously questionable government contracts for his companies. SpaceX might be profitable (or not), but it’s certainly the anti-NASA in its refusal of wonder, science and excitement. No one wants to face that fact. Now, thankfully, they no longer have to.

>a-at least the landings are cool though
"No!"
The camerawork is dreadful; the landings of the charred boosters are boring. As I watch, I noticed that every time a Falcon 9 lands, Musk said either “self-sustaining civilization on Mars” or “imagine if you had a 747 and you threw it away after one flight.”

I began marking on the back of an envelope every time one of those phrases was repeated. I stopped only after I had marked the envelope several dozen times. I was incredulous. Musk's mind is so governed by clichés that he has no other style of thinking. Later I read a poorly-written news story on SpaceX by some fat web blogger. He wrote something to the effect of, "If these kids are watching these launches now, surely they will work for SpaceX in the future and they too can have paychecks based off of government handouts." And he was quite right. He was not being ironic. When you are a SpaceX fan, you are, in fact, trained to be a mindless supporter of government-funded billionaires.

I hope Bangladesh is happy with their LARGE SUMS OF FOREIGN CURRENCY

>>9734779
The name of the other drone ship is Just Read the Instructions

>>9734779
it's from an Ian M Banks book. They're actually quite good sci fi novels. Just don't go into them expecting clark/Asimov/etc quality

Good thread everyone. Next launch is May 19th, with Iridium-6 / GRACE-FO. It's a reused core, previously having flown Zuma.

>>9735198

>>9734673

>>9735204
I watched it on TV, dunno about you

>>9735204
The stream for Rosetta was pretty much ESA big shots congratulating themselves (usually with horrendous French accents, and I'm French myself). Obviously, a stream of something with live video will be more engaging than one without.

>>9736369
*Northrop Grumman

>>9736431
oh yeah

>>9736491
Yes, the same people who are building/breaking the JWST at the moment...

>>9736575
It’s crazy how Zuma probably did cost a couple billion dollars, if those senators are to be trusted

>>9734702
Literally the dumbest shit I've seen all month. Whoever made this should rethink their life.

>>9736575
Northrop Grumman is a patriotic company that works for the public's interests and has done so for decades. Criticism should be aimed at those disruptive startup companies who seek to exploit the tax payer by seizing subsidies using borderline pyramid schemes...

>>9736582
It's even weirder they then decided to save a few pennies by letting SpaceX fly it instead of ULA which led to compatibility issues and the failure of the whole mission.

>>9736705
Either way they would be using a custom payload adapter I think. They didn’t use an off the shelf Moog one for a reason

>>9736705
>which led to compatibility issues and the failure of the whole mission
in what way?
