What is the minimum mass of a rocket capable of taking off from the Earth's surface beyond the Kalman line?

Question

Space

Actually, the whole question is in the title. What is the minimum amount of fuel needed to reach space? Are there limits to miniaturization? Assume that the payload is only the mass of the rocket.

Answer 1

If you are talking about the Karman line , then in 2004 a rocket weighing 328 kg was successfully launched , which rose to a height of 115 km. Maybe later and lighter ones were launched.
You can google "on sugar into space", there are many articles, interviews and videos on YouTube.
