Almost all of it is reusable unlike the shuttle. Shuttle would dump the main fuel tank and the boosters wouldn't survive many dips in the ocean.


The SRBs were mostly reused; only 4 were lost in service (including the two with Challenger). Some had, IIRC, 40-50 shots.

So really only the fuel tank was total loss; the SRBs and obviously the shuttle itself was reusable. Payload was nothing like the Falcon Heavy though.

Ah right. Did the SRB's require big overhauls though? Something in my mind thought they weren't very economical but maybe they were.

no matter about stage 3 it was never meant to be reused
I think he just gave a big fuck you to NASA and pointed the way forward

but hats off for the launch and the dual touchdown
did what he said he'd do Thumbs Up
may have overshot but it was a test launch

I never found records of the SRBs for Challenger if they were new or re-used but overhauling was maybe part of the reason Challenger exploded.

Cold temperature affecting o-rings in the SRB joints.

I've just been looking at pictures of this Falcon heavy. I take it it's not like the shuttle with an aeroplane type re entry vehicle.

It's 'just' a very fancy heavy launch vehicle. And I mean no disparagy by that. It was impressive technology.

It's not a space ship like the shuttle. It can't take men into space and bring them back.

Or can it, and I don't know what I'm looking at?

I remember seeing a documentary on the Challenger and IIRC it was a case of we have a problem, lets ignore this problem *boom*

The space shuttle brought astronauts back* all dignified like, other rockets drop you in a random field or ocean...

That's as far as my knowledge goes Very Happy

I assume they can put some humans in a tin can at the top. This is the current method they use on the Russian (60's) rockets still used to get Astronauts to the ISS on Soyuz rockets.

The ultimate plan for Mr Musk and SpaceX is to sent humans on a one way trip to Mars, he already has a waiting list i believe

MISSIONS TO MARS
Our aspirational goal is to send our first cargo mission to Mars in 2022. The objectives for the first mission will be to confirm water resources and identify hazards along with putting in place initial power, mining, and life support infrastructure. A second mission, with both cargo and crew, is targeted for 2024, with primary objectives of building a propellant depot and preparing for future crew flights. The ships from these initial missions will also serve as the beginnings of our first Mars base, from which we can build a thriving city and eventually a self-sustaining civilization on Mars.

Rolling Eyes Rolling Eyes Rolling Eyes Rolling Eyes Rolling Eyes Rolling Eyes

Quote:
A flat-earther who witnessed this week’s SpaceX launch says it was a hoax – and that Elon Musk has been ‘groomed’ to help fool people into thinking intergalactic travel is possible.

Justin Harvey, 30, saw the rocket take off from his home in Orlando, Florida, on Tuesday but is convinced the craft ended up landing in the Atlantic Ocean.

He thinks the launch, and other space exploration, is an elaborate hoax to distract people from the existence of other lands beyond an ‘ice ring’ that surrounds Earth at the North and South poles.

Justin told Metro US: ‘I thought, there’s another typical rocket launch, I’ve seen plenty of them.

‘I didn’t think too much of it.

I personally don’t believe in space travel, so I thought it was humorous at first, and then I was anxious to see the videos later, and see how real it looked

‘Even Elon himself claimed that it didn’t look very real

‘Most of the time the rockets do a parabolic curve, over to the Atlantic ocean, and they’re most likely retrieved out of the water.

‘They always go over and out, because what goes up must come down, and there is no outer space.’

Erm I wouldn't call it a fuck you, I'd call it a "Hey look I have enough funding to try all the stuff taxpayers don't want to pay for."

And as far as successes go, the only thing they did was managed to land the rockets back on Earth. Space X already admitted they failed at achieving the Mars orbit, which is very bloody important if their aim is to send people in that direction later.

Meanwhile NASA and the ESA managed this with the Cassini mission 21 years ago

https://www2.mps.mpg.de/images/projekte/cassini/trajectory.jpg

after which the probe orbited Saturn for 12 years, before being told to dump itself into Saturn's atmosphere, all as planned, and not before deploying the Huygens lander which successfully gave us images of Titan, Saturn's largest moon. 21 years ago. And this is just one random mission I thought up off the top of my head. There are tons. Voyager 1 is another great example. Or the Hubble space telescope.

So really I don't think it's a fuck you to NASA at all. NASA, the ESA et al have achieved far, far more than Space-X the space-tech engineering firm have ever achieved. All they did was successfully test a reusable rocket, which is great, but anyone who thinks this has put Space-X ahead of any of the major space agencies is just a sucker for public hype.

But NASA and the ESA also got inches confused with centimetres and trashed a few perfectly good probes a few times. They aren't perfect, but they have nearly 60 years of experience.

I think SpaceX is making good first steps, and it's great that they are prepared to do the investment in the technology. When private industry can do what government agencies used to do exclusively, that's a great sign for the future. If we can send people to Mars, that would actually give humanity a fighting chance for long term survival IMO.

We're so short-termist at the moment (we're all guilty of it!) but maybe interplanetary colonisation is the next big thing?

Yeah fair point, I don't necessarily mean Space-X is inherently bad or failing. More that it seems like it's going to become the Apple of the space agency world. Blind fanboys galore.

About Mars colonisation, I don't think it's feasible. Perhaps a research station because why not, but certainly no more than that. There's a reason humanity hasn't really managed to thrive in the Sahara desert, or the poles.

It's strange and almost like an Elon Musk cult. It's good the new private space race, as spending public money on expanding humanity's understanding of the universe seems to have gone out of fashion, but it does feel a bit like they're having to reinvent the wheel.

Yep.

Space-X obviously have the advantage when it comes to their self-landing rockets, because they've already done a load of automated/"A.I." stuff with Tesla cars.

I doubt, however, they have the faintest bit of capability in the plethora of other things that would be considered normal for a space organisation. Space telescopes spring to mind for me. Also space stations. Satellites. Space probes with all kinds of specialised sensors. Finnicky sciencey things that don't make headline news any more because we've seen enough clips of fancy metal objects drifting through space. Space-X have done none of that (yet), but for some reason people are already trumpeting them as the big new thing.

That's a good idea. Let a private company choose who gets to go to Mars?

You can go if you pay me 100 million. Doesn't matter if you are a Mike Ashley type person as long as you can pay.

Mind you, if I was choosing, the ladies would be checked out on the casting couch and sod any ugly scientists. Cool

I expect Elon would let someone travel for free if there was a good enough reason. Exactly how he'd define what's a good enough reason is up to him, after all, it's his rocket. Laughing

It wasn't about going to mars, it was about putting satellites in orbit as cheaply as possible.

With resuable rockets, he cut the price by a factor of 10. He can now lift bigger stuff than anyone else a factor of 10 than anyone else, who also can't lift that weight.

The Falcon heavy isn't designed to put people on mars, the bfr (big fucking rocket) is geing designed for that.

since the hey day of the shuttle NASA has been going backwards
there current SLS system has been pushed back to 2023 and expected to be even longer if the funding is not improved

SpaceX is taking over as are other private ventures (Beardy Branson, Blue Origin and a slew of others)

Russia is tied up with the ISS & Military and not really interested on the moon or mars
they have done very little in that direction for years

China & India have a bit of catching up to do with everyone

so for now the private sector seems primed to lead the way and so far Musk is in the lead there and has got quite a few contracts under his belt

Isn't the ISS all about investigating the long-term effects of space travel on the human body, and conducting other experiments? Firing a big ol' rocket to a Mars orbit must be something a private company could do relatively easily compared to the challenges of establishing a settlement, about which they'll know very little. I reckon NASA and the like are making careful preparations. The two booster rocket landings were Gerry Anderson cool though.

Privatising the act of taking things from Earth to space, is all that has happened. Not exactly a giant leap for mankind.

I think there will be quite a lot of NASA and ESA bods who are quite a bit peeved with the Space X hype right now. Loads of utterly clueless fanboys are sat getting boners over the Musk Phallic Object, blindly jumping to the conclusion that Musk and his crew just are the best at doing space stuff now, no questions asked, because a single clip of a rocket doing rocket things on TV said so.

Kawasaki Jimbo wrote:

They are. https://www.nasa.gov/topics/journeytomars/index.html

And, come to think of it, Mars prep was talked about ages ago, with a 1 year long mission in a closed Mars-like environment on Earth, and I think something happening on the ISS too.

But meh it wasn't Elon Musk so who cares, Space X are still the best, he's the god of reinventing the wheel everything.

Sounds more and more like Apple and the Steve Jobs bum club every day, it really does.
