A rocket enters space at the Kármán line, which is at an altitude of 100 km (62 miles) above Earth's sea level. This boundary is internationally recognized as the point where aeronautics end and astronautics begin.

FAQs & Answers

  1. What is the Kármán line? The Kármán line is defined at 100 km (62 miles) above sea level and marks the boundary where aeronautics end and astronautics begin.
  2. Why is the Kármán line significant? It serves as the internationally accepted boundary between Earth's atmosphere and outer space, important for aerospace regulations.
  3. What altitude do rockets reach during launch? Most rockets reach the Kármán line and often exceed it during launch to enter the space environment.
  4. Who established the Kármán line? The Kármán line is named after Theodore von Kármán, a Hungarian-American engineer and physicist who contributed to aerodynamics.
