If you don’t know, this is exactly how the shuttle worked. It just makes handling contracts easier for NASA.

And of course if the shuttle program was known for anything it was for being cost-effective, coming in under budgetary projections and delivering the promised capabilities

It's sarcasm. Shuttle was expensive, hardly reusable, took far longer than expected for first launch, and a fairly dangerous vehicle.

That being said we don't have anything quite like it since and there's a lot of tasks we just can't do without it.

We couldn't have fixed the hubble without it. It carried and helped install COSTAR which was as big as a telephone booth. Fun Fact: The guy who came up with the solution did so while in a hotel shower - he noted the way the shower head was mounted and installed and it gave him the idea. Source.

My guy what was the orbitor then. Also the SRBs could be reused although due to how cheap they were it was easier to just build new ones.

The shuttle had to undergo a heavy refurbishment every launch, the tank and SRBs were expendable, even if they claimed the SRBs were to be reused. It was promised to be much more reusable than what we got in reality

NotAnotherNekopan t1_isrbdyb wrote

Exactly. And for what was reused, the cost associated with refurbishing it was far higher than anticipated.

There is no official accounting or source from NASA about the SRBs complete costs, which are very difficult to quantify because of the large nature of the program. NASA said they were potentially cheaper because of the frequency of launches (which was never substantiated). No group has ever released a source or study accurately accounting for all costs.

What we do know, is dumping metal into a salty ocean damages them almost instantly. There is a reason SpaceX lands their engines on dry platforms.

Nah, it was only 2% How many shuttle launches were there? 135? So really about 1.5% total vehicle loss.

Mortality is another subject entirely.

Also, about 4 percent of people who flew on the shuttle died on the shuttle (14 out of 355).

Not a great success story to emulate.

Does it? This project is late, over budget, and keeps on awarding big bonuses to the primes. Which of these problems is improved by setting up a joint venture?

Fuck SLS.

Just strap the Orion to the top of a Falcon Heavy.

For one, ittl work. Two, ittl land itself and be exponentially cheaper than this corporate welfare shit show.

MaltenesePhysics t1_isrkxm7 wrote

While I’d love to see this, FH doesn’t have the performance margin to lift Orion to the moon in a reusable configuration. Slapping it on an expendable Starship-derived upper stage and flying it on Superheavy? That’s more feasible than a FH-Orion combo.

Shrike99 t1_isryord wrote

Falcon Heavy in expendable configuration is still an order of magnitude cheaper than SLS. Though even then you'd need some extra development to get it to work - propellant crossfeed, or sticking the ICPS on top of S2.

Starship-derived is definitely the better solution.

Falcón heavy is not human rated, and will never be. Also, SLS is 80% more powerful.. so no, it doesn't work.

>Falcón heavy is not human rated, and will never be.

It could be if the desire was there. SpaceX originally planned to do it when they had a customer who wanted to fly on it, but after the customer changed their mind SpaceX no longer had any reason to do it.

If NASA asked SpaceX to crew-rate Falcon Heavy, it would be done. It would hardly the first time SpaceX changed their minds in order to meet NASA's requirements.

Also, the fact that Falcon 9 is crew rated, currently flying on a regular basis, and arguably the most reliable launch vehicle in history means Falcon Heavy is starting from a good basis, moreso than SLS I'd argue.

>SLS is 80% more powerful

In terms of raw thrust, sure. But it's also very inefficient, such that in terms of payload capability it's only around 25% more capable to TLI, and most of that is from the high efficiency upper stage. If you put a similar high efficiency stage on top of Falcon Heavy (traditionally the SLS's ICPS is proposed, but Centaur V would be even better) it actually gets pretty damn close. With propellant crossfeed in the mix you'd all but match it.

Such developments would take time and money, but would still likely be cheaper than SLS in the long run. However much like with crew-rating SpaceX would prefer to focus on Starship, and NASA currently show no interest in developing such capabilities, though the previous administrator did raise the possibility.

$3B per launch doesn’t work either, regardless of the paper performance.

SLS is really quite the accomplishment. A rocket too expensive to launch.

Falcon Heavy will be human rated if their is a customer to pay for it. SLS is years away from being ready to carry humans. Falcon Heavy could easily be ready to carry humans before SLS is ready to carry humans.

Elon said that will never happen, SpaceX is betting on starship.

>SLS is years away from being ready to carry humans.

SLS is ready to carry humans right now, of course it needs to be tested first. But it is already human rated.

>Falcon Heavy could easily be ready to carry humans before SLS is ready to carry humans.

Again, Elon said that will never happen.. and regardless, it doesn't have enough power (remember the 80% mention before).

seanflyon t1_isrnrgu wrote

> Elon said that will never happen

Do you have a source for that? Specifically that they would not do it for a paying customer? From what I recall they have said the opposite. You may have heard a statement that they don't think they will ever have a customer want to pay to human rate FH when Starship is better and cheaper.

> SLS is ready to carry humans right now

Either it is ready or it is not. It needs to be tested first and will not be ready to carry humans for a few years assuming everything goes according to plan. It would be ridiculously dangerous to put humans on an untested rocket, not to mention the capsule on top does not yet have a full life support system and the Artemis 1 launch will not have a working launch escape system.

I don't know how one can say it's ready for humans now, but needs testing first with a straight face. That is literally not being ready.

MaltenesePhysics t1_isrl8jf wrote

FH will never be human rated, but I don’t consider SLS human rated. The ECLSS is disabled/missing for Artemis 1, something absolutely critical for Human Spaceflight. It’s ludicrous that there’s no ECLSS on mission 1 to shake out issues, but that’s another story. It’s like they’re begging for something to fail on A2, when they could’ve just tested on A1.

Hussar_Regimeny t1_isrnaql wrote

> ECLSS

I should point out that the ECLSS has been tested extenstively on the ground already. Sending up with A1 will give little to no new data. The only way to stress test an ECLSS is to have humans aboard. Plus parts of it at the very least have been tested onboard the ISS

Plus it's not uncommon to not place the ECLSS on flights. DM-1 didn't have one and then DM-2 flew with humans and with the ECLSS for the first time. So this isn't the ludicrous action you think it is.

−1

MaltenesePhysics t1_isth0j0 wrote

That’s not true. DM-1 had its ECLSS installed and enabled. They ran into some issues with it during flight, even with no crew aboard. You can’t find unexpected issues with a system without having the system installed. It doesn’t make sense for them to not take the opportunity to test the entire system in deep space.

Boeing, Lockheed, Northrop, et. al. are so enmeshed with the federal government it’s almost impossible to see where the one ends and the other starts. They are at best quasi-government entities.

The big clue to this is you will almost never see a cost plus contract of these sorts in the private sector.

SexualizedCucumber t1_iswo9du wrote

Government contractors aren't allowed enough risk of failure and because of this, they drag their feet at massive cost to the government.

For example: If Starliner and SLS fails, Boeing will be at 0 risk of going under. If Starlink and Starship fails, SpaceX will almost definitely go under. So it's no surprise which of those two moves more quickly.
