Rikkitic:
On a different note, I notice how all the cut-and-paste media kept repeating that Space Oddity would be playing on a loop through the car radio. I don't really understand the point of the loop, since the car would have left the atmosphere by the time the song finished playing once, and sound doesn't travel in a vacuum, which would probably freeze or shatter the speaker diaphragm anyway, so Starman isn't likely to have been able to hear much. And while I'm thinking about it, what happened to the tyres? Did they explode or were they deflated before the launch?

The roadster would be using a single conventional car 12 V battery, for the radio and other essentials (not the powerpack).

Since it wasn't made for space, it likely froze.

I had the same thought about the tires. When I saw a picture, they looked like solid rubber tyres, not inflated.

The song is David Bowie's "Life on Mars?"

Maybe deflated slightly before launch?

We live in the deepest parts of the atmosphere – exposed to about 15 psi from the weight of air above us, and inflate our car tires to perhaps 40psi over that.

So I'd think if the car's tires were lowered to 20 psi at sea level they should only be at measured 35 psi in a vacuum?

Drill a hole in the tire? The stiffness should make it look OK in space.

Linuxluver: If we are to go to space at all, we have to use rockets.

Until a space elevator is completed yes.

Edit: or a Maglev Tram system.

Exploring Mars, having a research colony, yes, but moving there once we have ruined Earth, is ridiculous.

I think you are wrong about this. It won't be quick or easy (or cheap) but eventually it will definitely happen if we don't implode first. Not because we ruined earth (which would always be easier to fix) but because that is what we do. In a few hundred years, there will be permanent substantial settlements on Mars. In a few thousand, there will be plants growing outside and enough atmosphere for open bodies of water. in tens of thousands of years, genetically modified Martians will breathe the air and not be bothered by the radiation that still gets thorough. By then the research colonies will be throughout the asteroid belt and on the moons of Jupiter and Saturn and interstellar travellers will be heading for the stars.

This is a start http://www.science20.com/robert_inventor/blog/ten_reasons_not_to_live_on_mars_great_place_to_explore-118531

There is no magnetic field as the core has stopped, so solar radiation is 24/7. You could not live on Mars, you would live in a biosphere, and to house many people that would be huge. It has to get there, it has to be built. You could do this for exploration and we should. We cannot create an atmosphere as it will blow away with the solar winds. It would all need to be self contained and under cover.

The ease of fixing Earth would be massively massively easier. We have all the resources and we can work to that end.

To leave this place and colonise for the future a terrible environment is strange.We have everything we need here, and if we did "move" to Mars we will take our greed and self importance, need for power and control, with us. Rinse and repeat

With all the wealth and technology we have created we will eventually only use that to survive here, and even that will be massively easier than trying to create a semi liveable environment for the lucky few. We really need to a new governance here, where the Earth is one nation, and the MP's represent each country. Same currency, one people. Maybe that will happen when 2/3 of the population dies from famine, lack of water and disease. Perhaps a mix of communism, socialism and capitalism thats designed to out the Earth and the people first, so we can dispense with the so called "leaders"

Perhaps it’s time I mentioned the 100?

When (rather than if) something catastrophic does happen to the earth, it may well simply need a ‘lifeboat’ outside our atmosphere for the species to survive... whether that’s the moon (possibly too close if the event is Solar/inter stellar) or some space station/colony further off.

Let's Colonize Titan

"Saturn's largest moon might be the only place beyond Earth where humans could live"

By Charles Wohlforth, Amanda R. Hendrix on November 25, 2016

"The idea of a human colony on Titan, a moon of Saturn, might sound crazy. Its temperature hovers at nearly 300° below zero Fahrenheit, and its skies rain methane and ethane that flow into hydrocarbon seas. Nevertheless, Titan could be the only place in the solar system where it makes sense to build a permanent, self-sufficient human settlement.

We reached this conclusion after looking at the planets in a new way: ecologically. We considered the habitat that human beings need and searched for those conditions in our celestial neighborhood.

Our colonization scenario, based on science, technology, politics and culture, presents a thought experiment for anyone who wants to think about the species’ distant future.

We expect human nature to stay the same. Human beings of the future will have the same drives and needs we have now. Practically speaking, their home must have abundant energy, livable temperatures and protection from the rigors of space, including cosmic radiation, which new research suggests is unavoidably dangerous for biological beings like us.

Up to now, most researchers have looked at the Moon or Mars as the next step for human habitation. These destinations have the dual advantages of proximity and of not being clearly unrealistic as choices for where we should go. That second characteristic is lacking at the other bodies near us in the inner solar system, Mercury and Venus.

Mercury is too close to the sun, with temperature extremes and other physical conditions that seem hardly survivable. Venus’s atmosphere is poisonous, crushingly heavy and furnace-hot, due to a run-away greenhouse effect. It might be possible to live suspended by balloons high in Venus’s atmosphere, but we can’t see how such a habitation would ever be self-sustaining.

But although the Moon and Mars look like comparatively reasonable destinations, they also have a deal-breaking problem. Neither is protected by a magnetosphere or atmosphere. Galactic Cosmic Rays, the energetic particles from distant supernovae, bombard the surfaces of the Moon and Mars, and people can’t live long-term under the assault of GCRs.

...

Titan is the only other body in the solar system with liquid on the surface, with its lakes of methane and ethane that look startlingly like water bodies on Earth. It rains methane on Titan, occasionally filling swamps. Dunes of solid hydrocarbons look remarkably like Earth’s sand dunes.

For protection from radiation, Titan has a nitrogen atmosphere 50 percent thicker than Earth’s. Saturn’s magnetosphere also provides shelter. On the surface, vast quantities of hydrocarbons in solid and liquid form lie ready to be used for energy. Although the atmosphere lacks oxygen, water ice just below the surface could be used to provide oxygen for breathing and to combust hydrocarbons as fuel."

Tough one that. We know whats heading towards us of a size that matters, and the climate change disaster is a slow long term thing, time enough to plan. If it was nuclear those on regions that dont get hammered by fallout should be ok, maybe . If there was an asteroid on its way, then Houston, we have a problem.I;d see a modular space station, it gets added to continually. Probably need to send to to a Mars orbit, that all depends how much time we have, but if it was hundreds of years away, Earth orbit, then move to Mars, even at low speed to orbit there and live. Resources are there too, if we can find a away to pop up and down easier

An option. Takes 3 years as long as the starts are lined up so to speak. I.e. if there planets are aligned to allow a bypass from them so accelerate. But we would need to be self sustaining on the way, including all the gear needed to do what was required there.

Oh dear. I know someone on SM who trolls the F.E.S and so on, so get the odd organic reach post waved under my nose. And already they have pulled the video/stills appart and come up with their own theory to reverse the apparent mic-drop

It's been put into the 'it never left earth it was a studio trick' ring again :/

The fairing video was 'reversed', It went from RHD to LHD so the image was doctored, you can see studio lights (the ones mounted on the camera poles) which CLEARLY means it was in a studio, you cant see stars... and so on and so on

*facepalm*

On another note, heres what you don't see. Or rather hear on the video during launch. Play it out, the best bit starts about 6:11 after the photographers note the pressure waves in their lenses..

It's amazing the amount of effort some people to finding conspiracies.

The producer, who I suspect is an alien lizard, makes obsessive compulsives seem mellow in comparison.

I have a mate like this. Everything is a conspiracy. Everything. I take it as a person who wishes to remove themselves from reality and humanity, and wants to be different.
