could a large 12ft model rocket be used to launch a probe into space, such as a telescope?

Probably 4 ballons with the rocket between them, and use a RC/unit with an arduino or raspberry pi to control levelling and launching.

If you were to use all your kinetic energy at the surface of the Earth in 1 instant (time approaches 0 or power approaches infinity), you would need about 8 km/s as an initial velocity. This is the definition of "escape velocity".8 km/s where are you getting that figure?...That's 23 times the speed of sound. The max speed of the space shuttle was 1.3 km/s

Yes, it is possible for a rocket of ~12ft in length to reach space. The exact height needed to reach space varies, but generally it is accepted that the boundary of space starts at an altitude of 62 miles (or 100 kilometers). Rockets of this size have been successfully launched into space by various space agencies.
The size of the rocket does play a role in its ability to launch a probe into space. A smaller rocket may not have enough fuel or power to reach the necessary altitude to enter space. However, there are other factors such as the weight of the rocket and the efficiency of its propulsion system that also play a significant role in its ability to launch a probe into space.
The type of payload a ~12ft rocket can carry depends on the specific design and capabilities of the rocket. Some small rockets are designed specifically for carrying small payloads, such as CubeSats, while others may have the capability to carry larger payloads. The payload also needs to be within the weight and size limitations of the rocket.
The time it takes for a rocket of ~12ft to reach space depends on various factors such as the design of the rocket, the propulsion system, and the weight of the payload. Typically, it can take anywhere from a few minutes to several hours for a rocket to reach space.
As with any rocket launch, there are potential risks involved. The rocket could fail to reach the necessary altitude, experience technical difficulties, or even explode during launch. However, space agencies and private companies take extensive precautions and conduct thorough testing to minimize these risks as much as possible.
