hat doesnt sound like a very useful plan?
At least with previous missions there was some sort of purpose
I think Arianne 5 successfully demonstrated why a test launch with a cheap payload is worth doing before you go for paying customers, that failure cost something like $350M. The main purpose here was to prove the system worked, and generate some great PR which will presumably result in more investors, plus as said above the data they'll get back on the impact of the radiation on the way out.At least with previous missions there was some sort of purpose

If not careful this turns into launching a piece of space junk to save recycling on earth
Totally agree with you, a science package could have been included, many universities would have been delighted to have cooperated instead of the Marketing payload which is just more Junk in space, I guess Tesla sales have to be boosted (not meant as a pun).At least with previous missions there was some sort of purpose

For me what space X has done is capitalised on funding from NASA, utilised the R&D technologies that other companies initiated and can be traced way back to the mid 1990's, computing power miniaturisation of components and changes in manufacturing etc have all lead a path to what Space X do. Just like electric cars I suspect there will now be a wholesale change in Rocket design unless disposable ones can be brought down in cost to compete and used where applicable.

Best video of the two boosters landing - you can really see how fast they're going!
Amazing achievement!
Shadows are all wrong!!Best video of the two boosters landing - you can really see how fast they're going!
Amazing achievement!
Wow that is amazing.

Seeing it like that makes it even MORE amazing. Only seeing touchdown makes it easy to forget they are falling like a stone at hundreds of miles an hour.Best video of the two boosters landing - you can really see how fast they're going!

Incredible.

so space x launched anyway with their own balast.
Why should they send up some "science" package for free when they are paying for everything.
Interesting facts about the car:
and blows my mind!

WHAT WILL HAPPEN TO ELON MUSK'S STARMAN AND HIS TESLA ROADSTER NOW THEY ARE IN SPACE?
Where is the roadster going?
Starman was meant to be on a 250-million-mile (400m km) journey to Mars' orbit, propelled by the main module, which separated from the Falcon Heavy shortly after launch.
But in a slight hiccup, Elon Musk admitted SpaceX overshot the Falcon Heavy's third booster burn, sending Starman further into the solar system than was originally planned.
The new orbit will sent the Roadster on a journey into the asteroid belt between Mars and Jupiter.
What will happen to it?
The main force that will tear the car apart over hundreds of millions of years in space is radiation.
This will particularly affect the plastics and carbon-fibre frame.
'[Those materials] are made up largely of carbon-carbon bonds and carbon-hydrogen bonds,' Dr William Carroll, a chemist at Indiana University told Live Science.
On Earth we are protected by a powerful magnetic field and atmosphere that shields us from the worst of radiation from the sun and cosmic rays.
Radiation in space causes those bonds to break which will eventually cause the car to fall to pieces.
'When you cut something with a knife, in the end, you're cutting some chemical bonds,' Dr Carroll said.
'All of the organics will be subjected to degradation by the various kinds of radiation that you will run into there,' he said.
How long will it last?
'Those organics, in that environment, I wouldn't give them a year,' Dr Carroll said.
The well-secured inorganic materials, such as the aluminium frame and internal metals, would last longer, meaning it could still be recognisable in at least a million years. The carbon-fibre parts would be the last to go.
However, it is unlikely it will avoid all collisions with micrometeorites and other space junk in the meantime.
Before the launch Musk said there was a chance the car might hit Mars. Now on its new path it's not clear whether the car might run into some other space object.

Nobody wanted to pay to have their multi million dollar science payload launched into space on the maiden launch of a highly experimental launch system that was almost guaranteed to fail.
so space x launched anyway with their own balast.
Why should they send up some "science" package for free when they are paying for everything.
Given that NASA has provided Space X with funding $400-$500M $200 Million from private funding $100M from private investors and $100 from Elon in its first 10 years. its hardly 'their' money.so space x launched anyway with their own balast.

Highly experimental! any one would have thought no one had launched a rocket before, this launch was not made up on the back of a fag packet its on the back of hard science (known).
So getting back to just launching space junk sorry Marketing Junk. It would have been nice see a launch with a secondary Scientific purpose not just a marketing one.

Happy now ? secondary science yo'

They were testing their space suit in space before actually giving it to crew to wear on future manned missions.

You mean NASA didn't think of using a TESLA and a Dummy to test their space suits before going to the Moon, and there is no way a space suite can't be tested on Earth. Happy now ? secondary science yo'
Its just Marketing and Elon is good at that, I don't have any issues with a great marketeer but see it for what it is.

Does inspiring the next generation of engineers not count as a good purpose for the 'Marketing Junk'?Highly experimental! any one would have thought no one had launched a rocket before, this launch was not made up on the back of a fag packet its on the back of hard science (known).

Launching a car into space is cool. Kids love stuff like that. If it gives even just a few children/teenagers the drive to do something engineering related that they would have never otherwise considered, then I think it was a great thing to do.

Let me know how that turns out for you

Can someone explain to me why it appears to be rotating in such a way if in reality its being shot out away from earth?
Does the plinth rotate or something to allow a view like that whilst its travelling away?
