It took all of ten seconds to find that.

Oh, and yours alone shows plenty: Where's the brake disc, hub, strut? I know what a reflection is, thanks.. Oh, and that's not a reflection, that's a mud guard. Holy hell, it's like you've never seen a car before.

At this point we are only guessing, however....
During the end of the of the 2 hour plus live in space video you could see the car venting something, maybe battery coolant.
I am not convinced the car is a shell, however it could be.
I think that was residual propellant or fuel venting from the engine combustion chamber, though it could have been monopropellant too.

They may have removed parts that could have compromised the mission, like brakes and any small "loose" items. Maybe even the battery pack.  Now with a real pay load you normally you would not worry that much about that as the odds of something going wrong is slim, but the last thing you want is the cause of the mission failure to be because of your dummy pay load.  Now if the mission was specifically to send the car then they probably would have sent it as is.

Even the tires, I wonder if they were actually filled with some solid material.  Wouldn't they burst in space? 

It would be cool if they had made it so a solar panel module popped out of the trunk and that they could continue to communicate with it.  But then you need reaction wheels and a high gain transmission antenna etc...

Don't see it, sorry. Do you mean this reflection? (1st pic)

Or the A & B things in 2nd pic?
Yes, the A and B things. :)

They're probably solid filled just because of the temperatures. As far as the pressure goes, it's only 1 bar. Underinflate them by 1 bar and they'll expand just as if down here. And they'd probably take the overpressure just fine, too.

I don't see any disk brakes or a steering rack. Regardless of what's in the rest of the car, it's not a drivable car without those. The wheel doesn't seem to have a real axle either, which points towards it being a shell mounted on a frame.

I don't think there's gas in the tires. Not necessarily because of the pressure difference, but one of the tires inadvertently bursting could send the spacecraft into a spin or damage something. It's not as if people are going to kick your tires anyway.

OK, that's what I get for assuming the pic someone posted would actually be the best illustration of their point.
And I'd watched the Starman video before; didn't want to watch it again. It's cool, but not much action...

Anyway, better shot below. Yeah, it's been hollowed out.
I suppose the struts are attaching it to the booster rocket.

The point of the earlier picture is that you can see the actual struts. Those aren't normally inside of cars. It also shows the lack of parts you would expect. Having the Earth picture would just have people yelling that it's too dark to see anything.

Both imagines combined paint the most complete picture.

Even if the car was 100% in perfect condition, it is not drive-able because there is nothing to drive on.  But I wonder what would happen if someone could floor it and get the wheels spinning.  Would all the forces cancel each other?  Would there be any difference between front wheel drive and rear wheel drive?  My guess it would turn over end to end?

Regardless I find this amazing.  I just think this will confuse aliens.  We need new laws against confusing aliens.

My guess is they simply removed the valves.  The air would then escape as the launch vehicle flew into less and less dense atmosphere.

You remember that interstellar asteroid Oumuamua that passed through the Solar system recently?

https://en.wikipedia.org/wiki/%CA%BBOumuamua

The latest imagery would seem to show someone, somewhere, a long time ago, beat Elon to it.

I wonder how much fuel that booster has left?
Because it would be pretty funny if Elon has planned to soft-land it on Mars. Say, within camera range of one of the rovers.
He's talking about permanent eliptical orbits. But you never know with him.
Considering his planned BFR Mars mission rocket probably has the lift capability to bring that car back to Earth, imagine the sale price. "First private car to stand on another world."  He could practically fund the entire Mars project with that.

Landing on a planet that can potentially sustain life requires very stringent decontamination of everything involved. Landers are the most strictly regulated, with different tiers depending on the likelihood of contaminating the target body or area. The Curiosity lander has been decontaminated for surface duty and even it wasn't allowed to investigate salty streams found on the surface of Mars, as that would require even more stringent decontamination. Wet conditions are graded differently than dry conditions and the Curiosity team didn't expect to encounter fluids on the surface. Its successor is likely to be decontaminated to a higher level.

Landing the car on Mars isn't really something you can do on a whim. We're not even talking about the complexities of getting through the annoyingly uncooperative Martian atmosphere.

I would think that anything that could move on the car would have been thoroughly secured - welded probably. A rocket launch involves tremendous vibration and stress so things like the suspension - which may end up vibrating sympathetically - would be locked in position. Further, none of the plastics/synthetics/oils/greases/seals/paint are rated for use in vacuum, nor the temperatures and hard radiation to be found in space. The car will be destroyed pretty damn quick, it might not survive in one piece for even one loop out to the asteroid belt and back.

There's no suspension any more, at least not in the front. I also imagine UV radiation wreaking havoc on the carbon and plastic panels. Even with the protection of the atmosphere, plastics quickly deteriorate to dust in sunlight. If the car is spinning there will be thermal stresses too.

Yeah yeah yeah, we all know this. But you are forgetting that Elon is proposing to have humans on Mars by 2025. So much for bacterial sterility. Also, his proposed mission involves a lot of rocket-braking on Mars entry.

I was _partly_ joking about landing the car.  But not entirely. Hence wondering how much fuel (if any) the booster still has.

Btw, I'd missed the news of salty streams found. Thanks, now to go googling. You sure you're not thinking of Liberal tears?

Regarding placing third party experimental payloads such as those from AMSAT, this has been done several times on test launches particularly with Arianespace until recent years. Then the aerospace engineering company became an accountancy conglomerate with a few engineers, and since then free rides have been elusive.

Arianespace gained quite a bit from AMSAT's involvement. Firstly, they pioneered the adapter rings that allow multiple payloads on board Ariane rockets, spreading cost from the prime contractor across secondary payload customers. They also act as an open organisation for platform and integration demonstration for Ariane's customers: most launch customers don't like third parties sniffing around their IP during integration.

Yes, AMSAT have had launch failure, such as the Phase IIIA launch failure in 1980 which saw global news coverage at the time. The reaction to this by AMSAT was immediately to try again. Frankly, if you go into space, and can't accept any risk of failure, you should find something else to do with your life.

The difference nowadays is the degree of risk-averseness, and that includes such things as mitigating against the risk, say, of an in-orbit collision of multiple launch objects. As such, insurers have become key parts of the equation, and the associated costs of that, which can be prohibitive.

The car itself, well that will not be simply a car popped into the faring with a few bolts. It will have been through substantial thermal, vacuum and vibration testing to mitigate against such things as outgassing. I doubt there's much actually inside the body, and what's left will have been highly modified to satisfy the aforementioned testing.

As soon as humans touch Mars, quarantine is obviously over. Humans are terribly messy when they live or even go somewhere. There's bags of poop on the Moon. However, we're currently sending various robots there with the explicit purpose of looking for signs of life. We haven't really done that before. Other than the quest for life having pure scientific value, we're also trying to answer the more morally loaded question whether we might destroy a unique branch of life by going to Mars. Finding life might ultimately mean not colonising the planet, though that's a complicated discussion.

Are Ozzies doing this horrible liberals versus conservatives thing now too? I have trouble understanding how people relish in basic tribalism while whole countries tear themselves to shreds.

We might destroy some odd form of mold or something on Mars.
Survival of the fittest is the rule of the day.
If we are to survive as a species we need to reach out and colonize space, including Mars and anywhere else habitation is easy.

One simply mold could learn us an amazing amount of things about ourselves and the nature of the universe.

Killing the first otherworldly life we find isn't a good look either. Space is quite big. There's other places for us to go. Unless the entire solar system turns out to be teeming with life making it literally impossible to avoid, we should be able to not act as pubescent as we've done in most of our history.

We need to see this as what it really is: A brilliant publicity stunt. Definitively beats a Super Bowl ad.

Look right now how the web is trending with these stories. How many more people will now consider purchasing a Tesla.

I'm almost sure that Tesla will be inundated with orders for similar red roadsters.

Unfortunately this red Tesla roadster was from 2008 and the model hasn't been manufactured for several years. The new Tesla roadster is not ready yet (probably several years away).

I am of two minds on this...
On the one hand I agree with preservation of life, however we like every other form of life on this planet are programmed from the genetic level to succeed.

For us as humans time is short; we need to get off this rock within the next ninety or so years, or we won't be able to and that will lead to our extinction.
Sooner or later...

The whole solar system is teaming with bacteria. Comets contain in their ice amino acids, it is theorized RNA may exist in some form in comets.

From a purely evolutionary point of view we are suppose to colonize the planets, and down the road, the stars.

We like to think of ourselves as being civilized and having a high moral standard, more humane... Truth be known; We are only slightly above the rest of the land dwellers, and maybe behind the whales and dolphins that are at the top of the food chain in the sea.

Overpopulation is not helping our cause, we need to get off this rock and get off now.
