Is it possible for a model rocket to launch something into a stable low Earth orbit

[From: ] [author: ] [Date: 12-07-12] [Hit: ]
In order to orbit one single gram of payload you would need a rocket of at least 1,000-2,000kg when fully fueled in order to achieve the necessary altitude and speed. I think your typical model rocket is much smaller than this. So to answer your question, from Earth,......
Not that I'd actually want to --
There's enough junk in space already. :oD

Observe the universal rocket equation: delta V= Vc*ln(M/m) Where Vc is the exhaust velocity of the rocket exhaust and ln(M/m) is the natural log of the Mass ratio, i.e Vehicle plus fuel mass divided by payload mass. Orbital delta V is ~12,000 meters/second allowing ~1/3 of this to compensate for atmospheric drag. In order to orbit one single gram of payload you would need a rocket of at least 1,000-2,000kg when fully fueled in order to achieve the necessary altitude and speed. I think your typical model rocket is much smaller than this. So to answer your question, from Earth, no; your rocket is way too small for the task.
I would recommend moving to Ceres or Vesta or Charon where the surface gravity is much lower if you want your model rocket to actually achieve orbit.
P.S. I heard the the US Navy has extensively studied the possibility of placing payloads into orbit using a giant gun (for cargo only)(the Navy really digs giant guns) and it looks promising. Jules Verne would have approved.

Kinda depends on what you mean. Is it possible to walk into a hobby store and buy one of those little rockets that could put something, even with extensive modifications, into orbit? Uh.....no. Is it possible to build a rocket that would put something in orbit yourself? Yes, it's possible. It would be VERY expensive, and you'd have to really know what you're doing to get it to work. But it's "possible".

Possible ? Maybe, but nobody has done it yet.

On May 17th, 2004, the Civilian Space eXploration Team sent a 328 kg (724 pounds) rocket up to 115.793 km. That's well into "outer space" territory, but the rocket didn't go fast enough to put anything into LEO. We need a speed of 28,080 kph (17,400 mph) to stay in orbit.

Not nearly. You need a big rocket carrying a lot of fuel with a high exhaust velocity. Also a sophisticated guidance system to actually place it into orbit.

If it does the real thing, I guess there is not much reason to call it 'a model' then any more...

-
Not likely.
