Astra is in a hold rn

boats

>>11967635
On one hand, they probably shouldn't be doing that, but on the other, the way people are seething about them makes it totally worth it.

Astra’s rockets look like old school ICBM’s, and are a lot smaller than I expected... also this whole time I thought they were the same thing as Ad Astra

>>11967638
not to stir the pot more but it's a shame a legitimate safety issue is being muddled because of one dude's flag on his boat. ah well, it'll be fixed for next time and everyone will forget about it

>>11967641
yeah the whole trick behind Astra is that you can fit the GSE in one shipping container and the full rocket in another. Payload gets slapped in, you go vertical, launch, ezpz.

>>11967646
Whats the point of that?

>>11967644
Is that metal bit on the heel meant to lock the boot into the seat? Hadn't noticed that before.

>>11967650
I believe so

>>11967649
portability, quick deploy, sneaky, stuff the military likes

>>11967649
Quickly launch from unprepared locations without hostile foreign powers knowing ahead of time. Most of their money is coming from a DARPA research contract iirc.

>>11967658
and that money is quickly being funneled into environmental cleanup bills Alaska is sending em

>>11967644
What happens if you fart inside that suit?

>>11967667
why else do you think they have to air and dry them out after each wearing cycle?

>>11967667
The suits are plugged into the capsule's environment systems via the seat.

>>11967663
If only humanity was smart enough to destroy the environment.

>>11967667
>>11967677
Didn't Robert Zubrin create a vacuum chamber that could clean clothes?
Maybe just stick a chamber with a cage to hold the jumpsuit and open the exterior airlock on it

Did the barge deliver the hopper

Anyone know who was the CAPCOM for DM-2?

>>11967800
I'm surprised how easy it was for Spacex to set up a Dragon Control for a manned mission thb

>>11967800
All I know is that he wasn't Gary Sinise, so he wasn't good enough for me.

>>11967814
https://youtu.be/aozWYg8xbeU?t=407

>>11967800
Mike Taylor

>>11967820
I like to imagine that when our boys Bob and Doug strapped in to come home, Gary hopped into his replica Dragon simulator inside his house to start running through scenarios, just in case. His wife, standing timidly in the hallway, calls out "Gary, dinner's waiting..."
Gary stops midway through the sequence, furrows his brow, and takes a deep breath. "Moira, right now there's two American heroes about to make the long journey back home to Earth. A million things could go wrong, and that means I've got a million things to plan for down here. They don't get to have dinner up there tonight, so that means I don't get to have dinner down here."
It's a speech she's heard countless times, and it's a scenario she's lived through every Shuttle launch. She bows her head, resigned, and walks back towards the kitchen.

>>11967814
>yfw when they replaced Gary with a strong woman of color
it still hurts

>>11967814
Love that ride.

SmallsatFest after the hop tomorrow

Boat delaying Astra now. IT NEVER ENDS

Big beautiful Boca wall

>>11967879
>>11967883
Video from range

>>11967885
Trump should see if Elon wants to get into the wall building business.

>>11967902
What could Elon solve that a structural/engineering group couldn't? If the goal is fully securing the border, the issue is not the engineering, it's the funding and politics that are the real challenges. There have been hundreds of proposals for various projects to address this but none are approved.

>>11967909
Bad joke I guess. I'm aware of the roadblocks with getting a proper wall built

>>11967886
how far off the coast did it land? that is both hilarious and slightly embarrassing as an American

>>11967931
>slightly embarrassing
Nah, having the freedom to do dumb shit is what this country was founded on. Plus, it landed in international waters, so it's not like they could do a lot to get them to leave. The Coast Guard basically just recommended people avoid the area.

>>11967902
I don't support the wall but I would be fascinated to see an Elon lead proposal for the wall.

>>11967945
Communist

Let's say that in the future, after 25 successful crewed missions to the ISS, the 26th mission goes horribly wrong and a couple of astronauts die. Would that be the end of crewed missions to the ISS for Spacex or could they continue after a thorough investigation?

Elon needs to sell crew dragon shaped marshmallows.

>>11968018
>could they continue after a thorough investigation
Presumably they’d follow the same process that occurred after Apollo 1 and the shuttles. Politically, things might be more contentious due to the fact that they’re a private entity with enemies in the aerospace establishment, but there’s no reason to believe the fundamental process would be any different.

>>11966938
how many of them will try to sabotage spacex after elon musk's gender comment??

>>11967635
you never get an opportunity like this to stalk a spacecraft

>>11968018
they have an actual stated chance of failure which is something like 1/195, so it's not like they're saying it's perfect and never going to break. Everyone understands the risks involved.

bob got fat

>>11968036
uh oh i never thought of that

>>11968018
If US gov is smart, they will simply accept the risk and move forward. Its a waste of time/resources to simply shut down everything after they've achieved so much.

>>11968050
Bob still hungers.

>>11968050
if you notice, he's chewin something

>>11968050

How many Crew Dragon missions will there be to the ISS assuming the ISS deorbits in 2030?
Hard mode, include estimate for private missions.

>>11968075
The ISS will be orbiting Neptune by then

>>11968075
A few a year until Starship comes online

>>11967820
I can't believe out of all the things that have gone wrong with that mission, the heatshield and the parachutes didn't fuck up

>>11968089
why would you want america to turn into latin america 2.0. though?
>>11968090
i'm guessing around 25 flights with perhaps 36 flights in total (1 demo, 20 part of ISS missions, 10 private)

>>11968095
im guessing starship will reach orbit in early to mid 2021, but it wont start flying humans until 2023 or 2024 at the earliest. i honestly doubt starship will ever dock with iss though, that'll probably be reserved for the crew dragon for the rest of the iss' life

>>11968102
It's just that Elon Musk knows that ladders exists

>>11968108
a wall is a lot easier to patrol then a tiny fence though

>>11968050
He went over his allocated food budget for his breakfast before de-orbiting.

>>11967879
What‘s up with retarded rednecks in boats recently?

>>11967667
https://www.youtube.com/watch?v=wbAF1EExpek

>>11968139
They're hired by ULA, ULA boaters to delay and harass their competition.

>>11968148
>ULA boats fucking around to annoy splashdown operations
>SpaceX parking their barge downrange to prevent launches from the Cape.

Piracy is back.

who designed this logo

>>11967587
Haha, imagine the capsule doing a splashdown close to your boat and they have to exit it and you run them over with your propeller in Minecraft!

>>11967836
Hardly! It is remote controlled. The touch screen does nothing.

>>11968181
Bad-Dragon team.

>>11968164
Astra got cockblocked by a boat in Kodiak today too.

>>11968181
It's so good. Hope it sets a precedent for good patch artwork. The first starliner mission will probably have a shitty MS Paint patch

>>11968181
based and bad dragon pilled

>>11968181
>a SPACE DRAGON leering at the ISS while the Dragon capsule soars up beyond the Shuttle
I like it.

why is the dragon capsule so sexy but the trunk so fugly

>>11968207
It's a Bad Dragon with plenty of junk in the trunk.

Literally zero risk at all to anyone but there needs to be a 10 mile zone? Fuck off government bureaucrats

No one is in danger at all
If hypergolics are so dangerous then they shouldn’t be using em

>>11967644
>legitimate safety issue

It’s falling slowly with giant chutes, it’s not gonna land on anyone there
Even if it exploded or put off fumes it wouldn’t be a big deal, it’s not like anyone was climbing on it

Holy shit I just found out about /r/SpaceXFactCheck. I've never seen so much shizoposting. After getting btfo from so many SpaceX successes looks like the main mod has gone off the deep end and started writing cringe space themed erotica.

>>11968232
There's lot of sock puppet there too. These are all connected to anti-Elon/Tesla crowd. Some of them tried moving into anti-SpaceX territory but since they lack IQ they aren't getting anywhere. Instead they are hiding in SLS threads

>>11968254
>>11968232
One of the mod of reddit SLS forum was an anti-Elon poster before becoming mod of SLS forum. Once he became mod, his posting decreased, likely due to sockpuppetry accounts to shitpost other Elon projects.

>>11968232
This sounds amusing. By roddit standards i do enjoy the shitpostimg on r/highstakesspacex

SN5 hop window opens in 7 hours or so yeah? I really want to watch but it's going to fuck me staying awake too late. Thinking I should have a nap after work.

As much fun as it was watching the boats buzz the dragon. I'm sure nasa will require some changes to the recovery procedures
Nasa hates fun

>>11968181
It seriously bothers me that the spacecraft symbols are chronologically right to left, but otherwise, it’s a great logo.

>>11968318
It annoys me that it's all cool astrological symbols and then a cartoon shuttle silhouette.

>>11967885
they're finally doing something about the ULA snipers. now the only way for them to get a shot off and rupture the tank is with a helicopter which spaceX will just shoot down

>>11967587
So any BLM activist could just sail to capsule and blow it up.

>>11968345
Yeah, it’s a shame the shuttle program didn’t get a cool mythological name to keep with the theme set by previous programs.

>>11968357
Theoretically, but boat ownership in Florida is kind of exclusive to middle class boomers who aren’t exactly in the kind of demographic to do that sort of thing. They’ll probably have some kind of security for the next one, though.

>>11968068
Does he ever stops eating

>>11968417
Yes, when he's not suffering from post-flight nausea and trying to alleviate it with chewing gum.

Kek, all those Florida boatchads with trump flags, scott manley must be seething.

>>11968068
Bobndoug ate all ISS supplies!

>>11968345
>>11968361
The shuttle outline is a symbol in its own right these days.

>>11968185

Its similar.

>>11967587
dumbass coastguard
just document and then prosecute them later

>>11968456
He was.

>It's so far from the situation today that it's not really worth worrying about. You might as well worry about whether Starship is going to enable a Mars colony that will someday go to war with and attack the Earth.
SIEG ZEON

>>11968552
I will never understand why a manlet with such a boner for space exploration has so much hate for a president who is pro space exploration.

thanks for flying on spacex

>>11968085

Fucking boaters first interrupting static fire and now interrupting splashdown. Fuck boaters!

I AM GOING TO HOOOOOOP

>>11968703
Remember not to explode.

>>11968551

They cant do that. What those boaters did was not illegal, reckless yes but not illegal.

Next time, just have some Coast Guard boats, circle around the splashzone to create a visual and physical barrier between the boaters and the capsule. This will make it clear what distance is safe and still allows for spectators to behold it all.

>>11968742
In the end the smart thing to do would just be to disclaim that as long as boaters do not interfere with capsule recovery they are free to show up and watch, but if the capsule explodes and any spectator gets filled with shrapnel or poisoned by hypergols SpaceX, NASA, the state or federal government, insurance companies, etc are not going to be liable to compensate them anything. If they or their boat is damaged in any way due to an issue with the capsule, they'll be paying for it out of pocket.

>>11967940
>having the freedom to do dumb shit is what this country was founded on
dumb shit is still dumb shit, even if legal and what the country was founded on
in other words this country is a safe space for retards

Boot swallowing authoritarians will not be tolerated in the United Planets of America.

>>11968219
If hypergolics aren't dangerous why don't you drink some and report on your findings?

>>11968742
Not exactly right. Even in international waters if you’re an American vessel USCG can enforce their own keep out zones on you etc etc

HOP WHEN?

>>11968834

>>11968879
Alright folks, back to work. Lots of welding test cases to complete.
Hop should happen today if there are no ground equipment issues.
The engineers are getting impatient with us.

>>11968792
Post your smart countries achievements in space
People should have the freedom to potentially hurt themselves, and there is not thread posed by them being close other than a risk of the hypergolics exploding or leaking, which is a bigger issue for the crew in the capsule anyways

That's like saying give up on firearms because Kevlar exists.

So no VASIMR engine bros???

>>11968629
Apple doesn't allow for individual beliefs in it's cult. I'm not going to make any assumptions about what Scott actually believes because no matter what it is he'll toe the line or they'll excommunicate him from his job. They've already maliciously fired other employees for any level of individual thought before.

>>11968108
>muh ladders
So because ladders exist, we should just have completely unregulated immigration into our country??? We don't have a stable enough welfare network to manage an influx of millions of people
>ALSO
The more poor people we let in from poor countries, there the per capita carbon footprint is low, the more we pollute
the USA has one of the highest per capita carbon footprints on earth, the last thing we need is a few million more people let in to be elevated to that level, that's very damaging to the earth, life isn't fair lmao some people are born losing
Immigration from poor countries into rich countries is damaging to the environment, and speeds up global warming

About tree fiddy

Anon at least tell us if they also have froyo in boca like back in Hawthorne

Stop discussing politics

How well would this work? I'm thinking of using paintball CO2 canisters

>>11968972
I don't know for sure and I don't have the time to check but make sure that the CO2 isn't going to dissolve in either your propellant or oxidizer. Pressure fed systems are well tested and proven to work, they are good when mechanical simplicity is needed but hinder your rocket's delta-V due to the excess wet and dry masses which don't directly contribute to propulsion.

>>11968974
I said CO2 canister, not CO2 gas. By that I mean the empty bottles.

How do you convince your lady friend to let you go away for long durations of time doing dangerous things?

Possible hop today? What's going on with that?

>>11968958
this reminds me of 8 1/2

Is it me or was yesterday's event seem to be blacked out my MSM? I couldn't see much outside of handful of local news media. None of the big journos are reporting it, and if they are, its about how "trump boats ruined it."

What the fuck?

>>11968983
I don't think people really understand the inherent tension of a capsule splashdown. It's much less obvious than a rocket launch, so it seems boring and routine and probably doesn't make great news.

>>11968983
A bunch of retards on Twitter saw the boats, and that was enough to ruin the entire awesome moment
>REE I CAN'T HAVE FUN AND ENJOY THINGS BECAUSE SOMEBODY EVEN SLIGHTLY MADE THE SITUATION RELATED TO TRUMP REEEEEE
Fuck Twitter

>>11968980
A week away

>>11968980
Hopefully later today. There's today/tomorrow for road closures and FAA permit.

>>11968972
Compressed air is probably the last thing you want to use. They use helium because it's so light and it won't cause engine burps. Air is heavy as fuck and is almost guaranteed to cause burping and misfiring.

>>11968983
Normies don't care about the return, only the launch.

>>11968978
Safe pressure seems to be about 850 PSI or about 58 bar, it will be more expensive but you might want to use an HPA tank instead, they can pressurize up to 300 bar.

>>11968998
Furthermore, the air will dissolve into the propellant/oxidizer, contaminating it and reducing performance. It's just like a soda streamer.

>>11968994
>>11968996
I want to HOP dammit, NOW

>>11968979
Promise her she can go on the next one? (without you of course)

>>11968980
LabPadre stream chat is all confus because they can't update the "No hop today" message in the video right now. Apparently there's a new FAA TFR for the 4th/5th, but the old one for the 3rd/4th may still be in effect. So I just closed the video and left the pop-out chat running on my laptop until I hear that the parking lot has started clearing out.

Why does labpadre say "No Hop Today" also?

>>11968999

The hop is a week away, and will still be a week away next week.

Wait, you mean HPA tanks like this

I really, really hate political discussions in spaceflight threads. Because they are wasting time I'd rather read about engines, fuel, orbital mechanics and other things relevant to actual spaceflight.

>>11969139

Skylon is vaporware, plus a TSTO fully reusable spaceplane makes more sense on paper
Everybody should copy the old Lockheed martin TSTO space shuttle design or Starship

>>11968983
You're retarded. it got a bunch of coverage on MSNBC at least.

>>11969163
The Skylon concept made sense back in the 1980s when it was called HOTOL and the idea of having enough processing power and materials science to make an orbital-class vehicle land vertically like a harrier was absolute science fiction, so that spaceplanes were the name of the game when it came to reusability.

That was 35 years ago, though, and spaceplanes should have been eliminated from consideration as anything other than crew lifeboats from the very moment that the DC-X first flew.

I always thought people could just attach a giant solar sail to a shit, and then point a bunch of lasers on board to simulate solar radiation pressure and to fly around without expensing propellant that way.

you can, thats actually probably the best interstellar propulsion method, in fact a group called breakthrough starshot want to build a laser array to accelerate tiny probes to 25% of light speed and send thousands of them to nearby stars

VTVL SSTOs will always be sexy, but after the USAF/NRO neutered the Space Shuttle and the Soviet Union ran out of money before they could build the flyback Energia, everyone just forgot about the idea of any sort of reusable first stage that wasn't a carrier aircraft.

Orion would have been oldspace kino if they'd fast-tracked both it and Ares 1 and had them ready to fly astronauts by 2012-2013, so that we could have had a solid decade and a half or so of NASA astronauts riding "the big stick" to the ISS.

Ahh yes the Roscosmos's answer to recent Crew Dragon success.

>>11969686
what is that

>>11969680
I think there's a Shuttle documentary floating around on YouTube which describes the Congress pleasing actions NASA had to do to keep the Shuttle during its development. That explains alot of the issues about SLS since it's derived from Shuttle parts.

And that was why it was oldspace kino. Nothing would be a more perfect metaphor for everything that was wrong with NASA than launching astronauts to the ISS in an overengineered Lockheed capsule atop Rube Goldberg rocket designed autistically around distributing its components to as many different contractors and constituencies as possible, a SRB+Hydrolox "El Abominacion" that cost the taxpayers 4x as much per launch as the venerable old Soyuz.

I am concerned. What is NASA as an organization? I'm so concerned because the brand has really been diluted over the years. I will keep an eye on SLS only because the money seems to be there to produce it. So why not make the best thing possible, or at least watch it.

>What is NASA as an organization?
An aerospace agency ultimately. Its goals are mishandled by politics, but it still tries to be a space agency.

>I will keep an eye on SLS only because the money seems to be there to produce it. So why not make the best thing possible, or at least watch it.
That's not how NASA funding works. It doesn't get a lump sum of money to do whatever. Each dollar is assigned to a project to be spent in a set way. Cutting SLS and redirecting the money is impossible, because canceling SLS would just take away the money being spent on it. It doesn't justify the misuse of funds on Congress' behalf but it explains why NASA is so constrained.

the boaters were kept at bay while falling. it was only after landing that they zoomed up to it. you can't have boaters accidentally ramming the capsule, or getting exposed to toxic fumes if there is a significant leak.

Territorial marking was out to 12 miles in this particular case. The capsule splashed down well outside the territorial boundary. As such, the coastguard had no jurisdiction to do anything. The boats DID move tens of meters back from the capsule once the coastguard cutter arrived and told them to move back.

>>11969793
Trumps the Saturn V... more importantly, it even overpowers the SLS (even in its final form). Hypothetically if we had an imminent asteroid impact and we needed to launch some heavy shit, how much could Starship lift if it were launched in an expendable mode

>>11969831
If SN5 fails, then SN6 is saved from scrapping and does 150m hop. They're definitely not going to risk 3 raptors before they've done a small hop.

>>11969821
Early to Mid september. They're going to go fast after SN5 hop.
>>11969835
I doubt the hop will fail, considering its a lot easier to land from 150 meters then from orbit.

>>11969793
>>11969837
That is in Starship's reusable configuration. A true apples to apples comparison would have it at around 300 t as a reference payload.

>>11969831
Depends on how it fails imo. If it makes a big enough boom or has major flaws, they might bring out SN6 to placate their own/the FAA's fears.

It's an enormous power hog. You need a 200MW nuclear reactor to make it work, and at that point you can skip the VASIMR entirely and use fission fragment for thrust plus MHD power generation.
>EMDrive is impossible no? Or am I retarded? I thought reactionless drives are impossible.
There's a new model where the conserved value is matter+energy+information and information is not constant between reference frames so you can cheat a bit. Current best results are 0.1N/kW but the researchers are filing a patent before publishing. This already makes it better than ion drives including VASIMR if the results can be replicated and verified.

So V*rgin Galactic just unveiled their render of a supersonic commercial jet. My first thought is that it's either never going to get built or it's a decade away, but even if they build it I'm struggling to see how it can be profitable with such high costs per seat.

It has capacity for 9 to 19 people, the Concorde could fit 92 to 128 people. It's faster than the Concorde but that also means it's going to be louder so there's going to be even more outrage when it flies over land. This screams investor fodder, Branson has already started selling his SPCE shares to fund other parts of Virgin.

While alot of the principle technologies that went into the Falcon 9 have been around for some time, the iteration used on the Falcon are much more modern. Such as advanced computing processes, streamlined manufacturing processes, and added resilience. Also, retropropulsively landing boosters was something no one else has done before. The closest example was the DC-X, but that was meant to be an SSTO rather than a booster. The Falcon 9's style of recovery is fairly novel and it surprised even NASA who thought that such a design wasn't worth doing.

>Not moving back in time
The Falcon 9 is among the most advanced rockets flying right now, and is the newest among those advanced rockets.

>>11970122
You do know that this would enable causality breaking nonsense, right?

>>11969302
>EMDrive is impossible no?
Yes, it‘s impossible. They took one, measured thrust, then turned it on its side and still measured the same thrust. That was years ago. Memedrive should‘ve died there.

>>11970109
Unless they can produce a supersonic commercial jet for a fraction of the price of a Concorde, I don't see it happening. Fuel costs have come up since the already high prices in the 1970s but if we assume they had the same expense on the same routes and just look at the seat capacity, the Virgin jet would have to charge almost 7 times more per seat at full capacity.

The average round-trip price for Concorde was $12,000. At 7 times more per seat, Virgin would be charging around $84,000. At that price, it's a very small market they're appealing to and being able to fly somewhere in a short period of time matters less today because all the work and meetings that can be done online. There will be more public outrage with noise concerns because there's no illusion the average member public will eventually be able to fly on it. They could be stuck trying to do overseas commuter flights in a decreasingly small market.

>>11970123
To be fair, Concorde more or less had a per-airframe cost that was on par with the B-2. That sort of ambitiousness in on aircraft design is really only feasible with state-level sponsorship (and state-sponsored carriers to buy it), good luck getting private investors behind you once you tell them that your Concorde successor is going to take $20bn to develop and will cost $700m per airframe.

Unironically our best bet for a true Concorde successor is probably the Chinese, if they ever learn how to build a decent afterburning turbofan, that is.

>>11970168
The math for profitability is a little more complicated than that, because you're bound by the time it takes to make each trip as well as the cost per seat. If you can make more trips per day, the per-seat margins don't need to be as great to amortize the cost of the airframe (or spaceframe) in the same time period.

Labpadre cam is at a nice angle to appreciate the size of that thing.

Bloody unlikely. Their latest greatest domestic plane is leftovers from cheap 60s/70s US planes with some modifications to the wings and they still had to import US turbofans to get it flying.
And I don't think the US is planning on selling them a lot of shit these days.

>>11970174
I agree, it's very hard to approximate the price difference, but I don't think we should assume that the Virgin jet will be popular enough to keep it flying that often with extremely high seat prices when the Concorde had only twice daily overseas flights at it's peak.

We could look at fuel costs which is the biggest expense in the airline industry. A 737-900 gets nearly 99 passenger miles per gallon, the Concorde had 15.8. It would be harder to operate the Concorde today because they were only competing against jets that had half the PMG of the 737. If the Virgin jet is twice as efficient as the Concorde, it would still only be 4.5 PMG, 22 times more expensive than the 737. This is why super sonic commercial flights will never have mass appeal until they get their fuel costs down.

the people to whom it is worth more all own/lease private jets and the ease of onboarding and on-demand destination setting are all worth much, much more. Not to mention the room to work/do coke/fuck prostitutes which Virgin's plane would be sorely lacking.

Can someone explain to me, how the fuck is it supposed to hop while attached to that massive steel structure?

It's resting on top of it

Richer people generally prefer comfort over speed, which is why they're usually not strapping themselves into extremely fast jets. It looks like a ticket on VG airlines could be twice the cost of the current most expensive plane ticket in the world which includes a small cabin and a bed. A single crash and VG would completely destroy their business.

Hopper was just an engine/flight control software testbed. This is the first actual flight test of the actual Starship design. Structurally, this is a completely different vehicle from the starhopper. Far lighter, too, which is why they've blown up so many of them trying to get the design right.

That camera wind noise is kind of kino through a home theater sound system.
It makes my subwoofer go all bouncy bouncy.
