Answer: B
Notes:
What is the Karman Line?
- The Karman line is the internationally recognized boundary of space.
- The line is named after Theodore von Kármán, a Hungarian American engineer and physicist.
- He was the first person to determine the altitude at which the atmosphere becomes too thin to support aeronautical flight.
- The Fédération Aéronautique Internationale(FAI) defines the Kármán line as the altitude of 100 kilometres (62 miles) above Earth’s mean sea level.
- FAI is an international standard-setting and record-keeping body for aeronautics and astronautics.
- However, not all organizations recognize this definition. The US Air Force and NASA define the boundary as 50 miles (80 km) above sea level. But there is no International law that defines the edge of space or the limit of national airspace.
