The Kármán line, or Karman line, lies at an altitude of 100 kilometres (62 mi) above the Earth's sea level, and commonly represents the boundary between the Earth's atmosphere and outer space. 2 k m s − 1. 5-9 miles from the surface to space. When we talk about Earth’s atmosphere, we tend to think of the region where air pressure is still high enough to cause air resistance, or where the air is simply thick enough to breath. Shortly after that definition was passed, the aerospace engineer Theodore von Kármán calculated that above an altitude of 100 km, the atmosphere would be so thin that an aircraft would need to be traveling at orbital velocity to derive any lift. Space Shuttle Endeavor silhouetted against Earth’s atmosphere. There are multiple answers, they are arbitrary, and it doesn’t really matter. Relationship Between Moon Earth And Sun . It doesn't work so that enough far away from the Earth, there won't be gravity any more. How far from the surface of earth to the edge of space - Answered by a verified Tutor We use cookies to give you the best possible experience on our website. The atoms and molecules are so far apart that the exosphere no longer behaves like a gas and the particles constantly escape into space. According to Newton the force of gravity falls off as the square the distance of the bodies that are attracted to each other. By 1993, NASA began collaborating with the Russians, the ESA and the Japan Aerospace Exploration Agency (JAXA) to create the International Space Station (ISS). Earth orbits the sun 100,000 times closer than the Oort Cloud, at an average of 92,955,807 miles (149,597,870 km). This layer is mainly composed of extremely low densities of hydrogen, helium and several heavier molecules (nitrogen, oxygen, CO²). However, other countries and agencies have a differing opinion on where space begins. Hi Zoutsteen, The drag curve is quite smooth as altitude increases. The official designation is 100 km . Any NASA test pilot or astronaut who crosses this altitude is awarded their astronaut wings. Although the object would tend to fall toward Earth’s surface because of gravitational force, its momentum would cause it to descend along a curved path. Join our 836 patrons! When I look at all of the conditions necessary for an infinite size, plus the implications of M-Theory, I am in the camp that believes that the size of the universe is bounded. Everyone has wanted to dig a hole down to the center of the Earth at some time in their lives. China lands ecraft on dark side of moon in world first how far above the surface of earth will a person s weight be earth is but a star excursions through science fiction to the far solved 4 how far from the centre of earth do you need to. Look up at the night sky, and what do you see? This is the point where the Space Shuttle would begin using air to maneuver instead of thrusters. In addition, in all three definitions, the measurements involved are beyond anything that we humans are accustomed to dealing with on a regular basis. Although the United States does not have a defined boundary, NASA considers the Earth's atmosphere ending and beginning at 76 miles above the surface. The flattened spherical nature of Earth is reflected in terms of its equatorial and meridional circumference. After a series of technical and structural problems caught up with the station, the Russian government announced in 2000 that it would decommission the space station. And in 2012, when Felix Baumgartner broke the record for the highest freefall, he jumped from an altitude of 39 kilometers (24.23 mi), less than halfway to space (according to NASA’s definition). How far (in km) is it from Earths crust to the nearest bit of Space (the place where you float)? The line owes its name to Theodore von Karman – a Hungarian American physicist who was the first to determine that around this altitude, the atmosphere became too thin to support aeronautical flights. This definition is accepted by the Fédération Aéronautique Internationale (FAI), which is an international standard setting and record-keeping body for aeronautics and astronautics. The air here is extremely thin, and the conditions here are more similar to the ones we find when we leave the Earth’s atmosphere entirely. The main advantage of putting something in this zone is that journey times to and from the satellite are short, and less fuel is used in transporting materials or crew back and forth. And if you think about it, Earth is little more than a tiny island in a sea of space. In Low Earth Orbit (i.e. But whatever the exact definition is, if you can get above 100 kilometers, you have definitely earned your astronaut wings!
