Is ULA actually looking to accomplish SMART reuse with vulcan?
https://twitter.com/torybruno/status/973517089859358720?s=20

>>11884195
Seems like it. Although, they seem to not have the hardware completed yet.

>>11884147
This proves nothing, means nothing.

>>11884195
SMART it the dumbest thing.
>oh but we recover like 70% of the cost 1st stage with the engines!!!!1!1!
yeah, for equally expensive rocket systems with full first stage reuse (say 99% recovered)... you're going to be 30X more expensive.

>>11884205
It was probably the best ULA could do when the design first came up in that awkward era of post-Shuttle pre-Falcon 9. It's clear that reuse is the way to go for rockets, but anything ambitious would immediately be compared to the Shuttle and later shot down.

>>11884210
It's a start. I hope the Vulcan is a stopgap for ULA to work on full reuse. I think they got caught with their pants down when falcon 9 reuse was actually practical. They were banking on it being unreliable and overall shitty. If ULA isn't working on full 1st stage reuse by now (and in place by 2027ish), they don't have a chance.

>>11884305
When will shitliner ever carry real crew? 2022?
They have a million lines of pajeetcode to fix.

Why hasn’t any other company or country developed reusable rockets yet? SpaceX has had them for five years, at the very least you’d think the chinks would have a falcon 9 knock off by now.

Elon Musk wished he was kek, but unfortunately for him he is not. The truth will be told and this world will know how much of a poser Melon Crust is.

TBF, that's the whole industry save for Blue Origin.

>>11884322
>Why hasn’t any other company or country developed reusable rockets yet?
The Shuttle set a very bad example, the economics for reusability didn't come to fruition until the second millennium, and for a long time the largest customer and funder for rockets has been the government to which money was no object.

>SpaceX has had them for five years, at the very least you’d think the chinks would have a falcon 9 knock off by now.
Rocket development is slow outside of Apollo due to limited funds and interest as stated above. SpaceX is the solve exception because their design philosophy is about failing fast and moving fast which sounds crazy to every other established aerospace company.

>>11884322
the market for anything larger than is necessary for a small sat launcher is completely artificial and not worth investing in. Musk only does it because he's autistic. Small sat launching systems are at a scale where reusability doesn't really make sense.

>>11884350
Everything about markets is artificial.

>>11884195
Its a compliance re-usability rocket. Its so they can apply for launches that require "sustainable" systems.

Fun fact: HTPB and potassium nitrate don't work as a solid propellant mixture. Either that or I messed up in the mix, or there's some anti-flame additive in the HTPB that I wasn't aware of.

>>11884514
yes

Ariane 6 confirmed NET second half of 2021

>>11884530
they put flame retardants into everything these days, nitrate being not fine enough, some ration was wrong, the HTPB had too long/short chains and didn't get enough activation energy/didn't release enough to get reaction going or some other reasons

ammonium nitrate should work better btw
potassium leaves ash, whereas ammonium burns to nitrogen (hopefully) - more gas - more pressure - more whoosh!

>>11884578
>didn't get enough activation energy
Could be this. I used a small Estes electric igniter and when that didn't work I scavenged a fuse from a smoke firework. Neither might not have the energy. I'll be disappointed if the rubber had some flame retardant in it because I bought it from a rocketry site specifically so it wouldn't have any retardants.

>ammonium nitrate should work better btw
I'll look into that. Thanks.

I think the idea has been that they'll figure out all the issues with the SN prototype line and once they hit on a design that works, they'll just copy it and elongate it for Superheavy, which is (basically) just a stretched Starship stage with more legs and engines.

C would they make a cute overall for him/her to deal with the hair?
D or would a dog be cooler? They'd have to make an EVA suit for 3 space walks a day.

when we finally learn how to manufacture long strands of carbon nanotubes, and weave them into ropes, who will waste the money and time on the first space elevator?

>>11885527
If we were to really to that, I suggest a ring be built first. After said ring is made, it can simply rotate the same velocity as earth and have elevators be built downward towards the earth simultaneously.

>>11885527
Hear me out - the primary problem with a space elevator is that the cable would have to be too big.
What if, instead of using a huge cable to tether to sea level, we build a flying platform. This platform remains permanently at 50,000ft allowing us to reduce the cable requirements.

>>11885527

>>11885797
What’s funny is that Starship is no longer a “paper rocket”. We know it can and will fly eventually, the only question is if it will be as cheap and as capable as intended.

But seriously Starship is doing great in terms of development. If SpaceX decided to build an expendable Starship right now they could probably have the Superheavy finished by October, and just refit SN5 with a payload adapter.

>>11885801

>If SpaceX decided to build an expendable Starship right now they could probably have the Superheavy finished by October, and just refit SN5 with a payload adapter.
300t to LEO would permanently cuck every other expendable rocket. You could carry an entire Antares as a payload.

>>11885811
>We know it can and will fly eventually, the only question is if it will be as cheap and as capable as intended.
I think eventually he'll reach his 2 million goal, but not til the late 2020s or 2030. For the first couple launches it'll be around the cost of a falcon 9 probably imo and eventually it'll reach the around 20million/launch after 25 or so launches. He might be able to get it down to 10million/launch after a year. The real question is cadence. I'm skeptical of one rocket launching 3 times per day, but I could see SpaceX rotating launches to achieve much higher launch counts then 3 per day once they a large number of starships and a large number of launchpads for them. For the first five or so launches though it'll probably be around one launch per month, and I can see SpaceX reaching multiple starship launches per week after a year.

>>11885797
>>11885811
Let's be very honest again. We don't have a commercially available superheavy lift vehicle. Starship may someday come about. It's on the drawing board right now. SLS is real. You've seen it down at Michoud. We're building the core stage. We have all the engines done, ready to be put on the test stand at Stennis... I don't see any hardware for a Starship, except that he's going to take 37 rocket engines and put them together and that becomes the Starship. It's not that easy in rocketry.

>>11885821
2m goal is just the marginal cost. It was always the marginal cost. Its going to cost similar to F9 or FH for the first couple dozen.

>>11885828
>for the first couple dozen

There’s nothing stopping SpaceX from just having a hangar full of Starships and Superheavies being used in a launch rotation. Like even if it takes three months to refurbish the whole stack, if you’re launching once a week, you just need ten to twelve stacks in rotation.

>>11885818
Unironically if I was Elon I’d push to get an expendable Starship flying this year just as a show of “hey, look what we can do”.

>SN5 is used for testing (as planned)
>SN6 is outfitted with three raptors, is used for SSTO or at least Suborbital mission and is destroyed.
>SN8 (which is currently being stacked) is used as the first operational Starship, only has three sea level engines, no landing system.
>SN9 is used as the first prototype for Superheavy. It probably fails
>SN10 is second Superheavy prototype, it probably fails too
>SN11 is first Superheavy equipped with engines. It is used for ground testing and static fires. It probably RUDs
>SN12 is a Superheavy test vehicle that never flies, but is filled with LN2 and pushed to the pressure limit while having a retired Starship (SN5) stacked one top. It RUDs, but successfully.

>SN13 is the first operational Superheavy. It had a minimal number of Raptors, but enough to fly a fully fueled Starship.
>SN8 is stacked on top.
>SN8/13 complete the first fight of a complete Starship stack. Both successfully complete their missions but are destroyed.

Timeline:

>SN5 tests: July-August
>SN6: August, tests to September.
>SN8: September (Built after SN10)
>SN9: August
>SN10: November
>SN11: November
>SN12/SN7: December
>SN13/8: December/ Early January

However, SN6 will still be used as an expendable SSTO in September.

For that matter is there anything stopping SpaceX from doing a Lunar or Mars landing without NASA’s help? Like if SpaceX just said “Hey we’ve tested everything we’re gonna send six of our company-trained astronauts to the moon” do they have to account for anyone?

not as long as they do all the proper planetary protection stuff

>>11885901

Nah I think all they need is FAA clearance to fly. NASA doesn’t “oversee” privatized space. They just dish out money for contracts and help human rate rockets if they want THEIR astronauts to fly on it. Once starship is ready there is nothing stopping spacex from flying private astronauts so long as they get clearance from the FAA to fly. (Remember that Elon originally planned to fly private astronauts on Dragon around the Moon. This had nothing to do w/ NASA. That plan has evolved to the cringey #dearmoon project. Yusaku and a whole bunch of artists are going to fly around the Moon and NASA isn’t in control of anything)

I mean desu Elon is the type of guy who isn’t afraid to push that boundary. NASA launches are slow because muh safety. If Elon has a fleet of 5+ starships, I can totally see him wanting to launch them all on the same day. Who gives a fuck? Let’s load and go. Starship is going to be the coolest thing ever if Elon can deliver what he’s promising

>>11885849
Falcon 9 has been reflying for years, and they still haven't got turnarounds that quick.

>>11886097

Probably still falls under the jurisdiction of the united states empire. Honestly I have a question for /sfg/. If Elon actually gets to mars and establishes a colony, and declares it a self-governing country, would you support him? (keep in mind this is hypothetical. If he did this the US govt. would confiscate all his funding and declare him an outlaw)

>>11886135
I really doubt a Mars settlement is going to be self sufficient before Elon dies, but I can see it being possible in our lifetimes (assuming average age of around 20-25)
With that being said, an independent Mars colony that also has the capability of colonizing other worlds would pretty much guarantee humans will never be a one-government civilization and mean we'd have societies and empires and republics of all kinds spread throughout the cosmos

>>11886078
couple dozen would imply at least 24 or more

>>11886158
elites wouldn't like that. i wonder for if that reason they'll heavily push against space colonization

>>11886158
Self sufficieny is hard but doable. Being able to make new Starship, electronics, complex alloys will be hard.

The way I see it, humans may become multi planetary in the 2020s, reach a minimum viable population in the 2030s, have a mars colony become self sufficient in the 2060s-2090s (No idea when because it’s growing too), and being able to make complex electronics 100% in situ likely some time in the 2100s-2200s.

>>11886158
>>11886200
Nah, Elon trying to make a one world government or starfleet or something would be so sci fi and gay; but I would be so on board to join. Mars could be like a confederacy or republic (it’s just semantics) with a united federal government consisting of independent colonies

How much will New Glenn cost to launch? It’s huge as shit but it’s engines are apparently 8 million apiece. Also that massive first stage is gonna need a lot of work at least at first to refurbish it.

New Glenn’s second stage is also pretty big and it isnt reused.

>>11886483
i don't know
however for some reason people stil think that NG has a lower payload to leo then FH

>>11886496
Well reusable Falcon Heavy can put 30 tons into LEO and costs $90 Million.

Falcon Heavy with the side boosters landing on drone ships and the center core being expended can put 50 tons into LEO at a cost of around $120-130 Million.

Fully expendable Falcon Heavy can put 60 tons into LEO at a price of $150 Million. However at that price, it’s payload to GTO is doubled compared to New Glenn.

Which half expendable? The top half will be working before the bottom half, but it can probably only barely SSTO, so there's no point except for re-entry tests. The bottom half is basically a big F9 first stage, and that's not exactly pushing the technology.
Remember, it's been taking so long to get to a hop because they keep fucking up the ground support during the pressure tests.
>>11886349
>>11886353
Also you can't make nuclear bombs using thorium, so no motivation from governments to do anything with thorium. Even if you could make the right plutonium, there's no equipment for doing much of anything with thorium right now.

Alright dumb question, but assuming NASA decided to add little window wipers to clean the solar panels, would opportunity still be functioning today? (yes I know it was only designed for 90 days but let’s just pretend it could clean its solar panels)

>>11886678
Either the wiper motors would have seized up first or it would have scratched up the solar panels and killed their efficiency.

>>11886641
probably not
we need boots on the moon and robits on dune

>>11886678
>assuming NASA decided to add little window wipers to clean the solar panels, would opportunity still be functioning today?
no, as dust on mars sticks to shit because of static and doesn't get caked onto things like it does here on our sopping wet earth
martian dust is also extremely small. like <5 microns small
wipers would just scratch the fuck out of the solar panels and shorten the rover's life unnecessarily, as they were only supposed to last 3 months
they should've had some kind of air compressor on board that could blow the dust off, but all that trouble for 90 days just wasn't worth it
out of all the things to worry about, people were panicked over the bouncy ball landing working properly
nobody even thought about the solar panels as the previous pathfinder rover from 1997 was supposed to last a week and instead lasted like 3 months

>>11886678
wipers wouldnt work, but even if you had some magic dust cleaner it probably wouldnt have lived much longer even assume the failure was just due to dust covering and not some other component
shit's old as fuck, the panels have degraded a ton and put out a lot less power even in good conditions, and a whole bunch of other stuff was already breaking down before it died

>>11886696
>>11886708
Is Mars regolith really that bad?? Like if I happened to be doing an EVA on Mars and tried to dust off its little solar panels would I basically be fucking everything up?

>>11886725
I don't know where you got that it's so bad out of that. A tiny gust of air cleans it off, it happens naturally on Mars with little dust devils.

>>11886725
imagine how many times the wipers would need to be used to keep the panels clean
a single wipe with your hand won't destroy it, but repeated use over a decade and a half will leave a lot of scratches

How is it that gravitational slingshots cause a net change in speed?
Doesn't the approaching craft spend the same amount of time approaching the body and being accelerated, and leaving the body and being decelerated?

>>11886503
I would be very surprised if it's not cheaper than Falcon Heavy. It's probably gonna be on par with Falcon 9.

- New Glenn (one stick) is almost definitely gonna be less expensive to make and operate than Falcon Heavy (three sticks)
- by the time it flies there will be a bunch of new generation rockets (Ariane 6, H3, Vulcan) which are expected to cost similar to Falcon 9 so it wouldn't make sense to ask more than 50-60 million for a launch. Customers don't care about reusability, they're just gonna pick the cheapest option.
- Blue Origin doesn't care about profit in the near term and Bezos is infamous for undercutting competition (see Amazon)

Honestly I'm excited to watch this race to the bottom. Also once there's not one but two cheap reusable vehicles, old space companies will have no choice but to adapt.

>>11886853
It takes a some orbital energy from the thing it slingshots by. Or you could fucking wiki it.

>>11886859
>NG is going to cost less than FH, all the oldspace shit is going to cost less than F9
Is this what oldspace genuinely believes?

>>11886853
That's just how gravity works. The object is falling towards something and gains speed.
Why do you gain speed when you jump out of the window of a skyscraper or a plane? Same principle. Gravity is a bitch, but we can make it our bitch in some cases.

>>11886875
Ah, that explains it well. I was getting confused by only thinking about it in the planet's frame of reference.

Well it technically puts you outside of anybody's jurisdiction but it would also make every country distrustful of your motives. Some shithole dictatorship might just decide they don't want your ICBM sized spacecraft overflying their capital during it's launch and try to intercept you. Considering that most human rated rockets accelerate no faster than 3Gs, an intercepting missile might even be able to nail you before you pick up enough speed to leave it's effective range. Launching from a relatively space-friendly country like the US or Russia is still preferable as long as you're willing to put up with the red tape.
>>11886135
Absolutely, I'm still hopeful America can be unJUSTed with enough hard work, but it is also inevitable that once space colonies become self sufficient they will begin to secede from the governments of Earth. Humans don't like taking orders and following rules made by people who they never know, never see, and who are never held accountable for the results. Once human populations get big enough they split, if there's no space to split then they fight, it's how we work.
Better to start shipping our population off-planet and let them do what they want (peaceably) out there then let the pressure build here till there's an inevitable balkanization.

Practicality > your fucking aesthetics.

>>11887282
They just need to design one from the ground up, I'm still convinced that XRS-2200 had relatively poor TWR numbers because it was running off the turbomachinery and plumbing of the anemic J-2 while also being designed during a time before computer modeling or additive manufacture.
>>11887295
Lack of necessity and ease of manufacture. Rockets spend very little time in the thiccque lower atmosphere where drag is a major concern, and most boosters are one-and-done expendable pieces of equipment, making them conformal would greatly increase their per-unit cost which is already fucking outrageous. Also it would only work for liquid boosters, since SRBs need their grains to be formed in a particular shape for them to work properly, and adding an aerodynamic shell over them with no propellant wastes valuable dry mass.

>conflating exhaust vector and expansion ratio
do your homework

>>11887452
>isn't the whole point of the aerospike that you get a perfectly straight exhaust regardless of altitude?
Total opposite. Research about aerospike engines again.

>>11887452
go back to aerospike 101

At lower altitude, the nozzles are pointed towards the side, at high altitude, it spreads out from it

>>11884453
they can make something this shape stable? where is all the fuel?

>>11887497
wait so the nozzles actually move depending on altitude? I thought it was passive correction and the nozzles were fixed. only the air pressure determined the spread

>>11887502
2 seconds in a search engine

>>11887506
Nozzles move, watch the video anon posted >>11887491

>that fucking high gimbal range
MUH

>>11887509
where exactly does it mention they move? The section about the 'boundry' says nothing about nozzles moving, just that as the rocket gains altitude the pressure on the nozzle is decreased because less air pressure so they boundary expands suggesting completely passive system

>>11887512
The boundary ie the nozzle walls.

>>11887512
It can be a passive and an active system with the nozzle being computer controlled.

If aerospikes are so good why haven't we seen any application yet?

>>11887605
the problem that it solves isn't really the bottleneck yet, but will be eventually

New?

This is why you aren't going to Mars.

Pure SSTO is only necessary when there are multiple heavy worlds with people on them.

>>11887633
we still have a couple hours at least, newfag

that's because the launches are booked years in advance for space probes and Falcon 9 only recently got certified for that
>>11886627
STARSHIP
CANNOT
SSTO
nothing can

>>11886790
that's the launch pad for Starship
it's a big metal ramp and a stool with some big water hoses
>>11887210
they'll be leaving forever afterwards
>>11887293
Dynetics suddenly starts looking really really good if you resupply it with Starship, anon

>>11887713
Starship can SSTO - just not with anythng resembling payload, heat shielding, or landing fuel.
