Karman lineDate: 15 July 2021 Tags: Space
Experts have doubted whether Richard Branson’s space mission reached a height that can be called as space.
Virgin Galactic recently made history when it reached space. This was the first manned mission by a private enterprise.
The space line is officially known as Karman line. It is located 100 km above the Mean Sea Level. US agencies consider it at about 80 km.
Virgin Galactic was successful in reaching a height of 86 km and qualified as space mission under US standards but international acknowledgement is yet to follow.
Jeff Bezos’ Blue Origin mission will go at a height of about 106 km. The Karman line has been named after famous aerospace scientist Theodore von Kármán.
It is similar to international waters as there are no laws governing beyond this point. No rules of Earth apply after crossing this limit.
Need for Karman line
By defining the point beyond which space starts, disputes can be avoided and space activities can be conducted smoothly.
It is after this point that rules of aerodynamics stop applying and free space takes over. This line also keeps space neutral.
Presence of space
There has been no clear demarcation of space. Based on presence of charged particles and winds of Earth, space is said to start 118 km above Sea level.
Some scientists believe that troposphere and stratosphere should be considered atmosphere and parts of mesosphere and complete thermosphere should be outer space.
