Model Rockets Capable of Reaching Outer Space

How much would it cost to build a model rocket that has no purpose other than to break past earth's atmosphere into outerspace, and just keep on
going?

A ton of money and one fast rocket with a stage that can burn outside the atmosphere. Once outside the atmosphere of Earth you would need a boost to get you out of orbit and the gravity field.
Saturn V is a good example of an Earth orbit breaking rocket, as well as the Delta (?) rockets carrying space bound stuff.
If I recall, to break out of earth's gravity field an object needs to be traveling at 6000 mph? I don't think you will see a model rocket break orbit and head out to space in the near future.
But what do I know, I could be wrong. Stranger things have happened. :-)

What definition of "model rocket" fits what you describe?

Steven,
I agree anyone would be hard pressed to get anything into space on 125g of propellant. I think the definition he was using was: non-professional rocket.

You could do it with a 50% mass fraction rocket...
and a fuel with a specific impulse of 11300 s....
and no atmosphere.

FYI - correction It's aprox 17,000 mph to MAINTAIN an earth orbit and escape velocity is aprox 25,000 mph.

Thanks Scott. I was a bit off.

All rockets can "burn outside the atmosphere". Propellant = fuel + oxidizer. No atmosphere necessary.

Escape veolcity for the Earth is in excess of 25000 mph.

Oh yeah sure - BUT - they won't go anywhere, since there's no air to push against.
Right?

I think roughly 13,000mph is required for orbit and 25,000 to break free of earth's direct influence.
now keep in mind escape velocity is a myth. their is no such thing as a minimum speed to break earth's gravity.
you can do it at any speed you want if you are capable of it.
25,000mph is required if you want to COAST out of earth's gravity without adding further power.
So if you want to go BANG and then coast you need 25k
since that is all we are currently capable of doing then yes you need 25k to break free.

If you consider 17,500 "roughly 13K"...

That'd get you close to geostationary when your landing gear retracts automatically. Guess you might see Pluto on that trip (and probably Donald, Huey, Dewey & Louie too), and if you've got enough propellant in yer tank, it's a fair bet you'd make a low pass as well ;-). Sure you'll need some extra for life-support equipment (chips, candy bars, bail etc.). Perhaps the mission'd be called the Bars Crawler?
