Will the Falcon 9 actually be reusable or just refurbish-able like the Space Shuttle?

The Falcon 9. The world’s FIRST reusable rocket. Wait. No it’s not. Do you remember the Space Shuttle? It had those solid rocket boosters and the orbiter, which were both reusable weren’t they?
Well, today we’re going to talk about why the Space Shuttle failed to actually be reusable and wound up being described with a more accurate word, refurbish-able.
People often cite the shortcomings of the Space Shuttle and are quick to point it to SpaceX’s claims of the Falcon 9 booster being reusable.
So today we’re going to look at what it took to get the space shuttle operational between flights, what it takes to get a Falcon 9 operational between flights, and why SpaceX’s first stage boosters take much less of a beating than the Space Shuttle.
We’ll also do a quick reminder of what technologies SpaceX added to their Block 5 booster to hopefully achieve their goal of making a rapidly reusable rocket that can truly be reused 10 times before needing serious refurbishment.

[@user-lv7ph7hs7l]

At the end of the Shuttle mission failure probability was calculated at 1/90. Then years later they did another more detailed study, knowing what they hadn't known before and they came up with the number 1/9. 1 in bloody 9. By that figure we should have lost 15 Shuttles. We got super lucky and the engineers took good care of them. And once Challenger happened everybody became pretty conservative. Still I would have flown on it knowing that. 1/9 chance of a fiery death with the payoff of riding the Space Shuttle to orbit? What a way to go. By my luck I'll probably die getting run over by car, so it wouldn't be so bad.

A more useful comparison would be based on capacity. The shuttle could lift 7 astronauts and ~20 tons+ of cargo to the ISS comfortably. Cargo could be enclosed or open in the bay depending on what it was and how packed. Now crewed dragon will be hauling I think only 3 people to the ISS (because thats all NASA wants on it) but can of course haul seven. So a valid comparison would be between 1 shuttle flight and 1 crewed dragon PLUS 4 cargo dragon flights to achieve the same cargo. So now you are talking about "refurbishing" and/or "reusing" 5 dragon first stages, 1 crewed dragon capsule and 4 cargo dragon capsules (all of which have gone for a swim). AND, on top of that you have jettisoned 5 falcon upper stages and 5 trunks (compared to 1 External Tank for the shuttle flight). AND you have had 5 times the launch/range overheads and potentials for issues (the more times you fly, the more chance of failure no matter how good the machine) Yes the shuttle was way more expensive and complex probably to refurbish. But the difference is not as large as you think when you look at the capacity capabilities of both system required to reach a given goal.

[@bftjoe]

Still cheaper/safer to run multiple SpaceX flights than the Space Shuttle.

[@johncherish7610]

The SpaceX company is more innovative than NASA the design will change in the future with new technology and materials much more rapidly than the space shuttle could.. The shuttle was a 1970 design with no innovations allowed. The military made it more expensive to refurbish by demanding such a huge cargo bay that made it heavier, where as if it were smaller and lighter it would have taken less to refurbish it and could have achieved its goal. Less weight on re-entry = less heat generated and probably less complicated. Material sciences of the time and computers back then also contributed to a less than optimal design. That said at the time it was state of the art but by today's standards was obsolete by the 80's and 90's. The real problem was NASA's lack of innovation and management, this is how it's done so don't question the methods used and come up with a better way. NASA a government agency is a bureaucracy and not prone to innovation.

@@johncherish7610 How can you say SpaceX is more innovative than NASA when SpaceX is just building on research that decades of previous launches from various space agencies gave us?

While I find these videos really informative, what really impresses me is the amount of time and effort put into producing them. Great work.

Very interesting, explained in plain language, a nice thought out article with lots of own content.

I see you also have a Lego Saturn V. I just finished mine, it's a beautiful model!

*heat is generated on reentry because the air is compressed to extreme levels* I'm sure you know this. but I noticed in your video you said friction Oh, then you said it right when comparing vehicles. Great work on the video. As always

[@elementus2857]

I have a name it's a combination of both friction and compressed air, when you compress a gas it heats up and if you rub against something it generates heat. So the shuttle is compressing the air heating it up but it is also rubbing against the compressed air causing friction

It’s probably better to think of it in terms of stagnation temperature instead of a PVT comparison. Yes, I know that in this case, it’s the Shuttle moving instead of the gas, but the Shuttle sees it as the gas moving so it’s the same thing.

Both

Pretty sure it’s electrons splitting from the atoms causing plasma.
