How many miles above us is the edge of the atmosphere? The Karman line, at 100 km (62 miles), is also frequently used as the boundary between atmosphere and outer space. For all intents and purposes, space starts at about 62 miles. And no, it has absolutely zero to due with the Earth's gravity.

Atmosphere of Earth The exosphere is the outermost layer of Earth's atmosphere (i.e. the upper limit of the atmosphere). It extends from the exobase, which is located at the top of the thermosphere at an altitude of about 700 km above sea level, to about 10,000 km (6,200 mi; 33,000,000 ft).he Karman kármán, line at 100 (km 62), mi or.157 % Of'earth s, radius is often used as the border between the atmosphere and outer. Space atmospheric effects become noticeable during atmospheric reentry of spacecraft at an altitude of around 120 (km 75). mi

To the Edge of Space In the mid-1950s it was decided that we needed a boundary between Earth and space and this would be in the thermosphere. The Federation Fédération Aeronautique aéronautique internationale declared that this would be at an altitude of (100 kilometres) 62 mles above. sea level

- The Earth's atmosphere stretches from the ground to about 300 miles up, although it is only breathable up to about 30,000 feet (6 miles).

- In the Thermosphere is a separate layer, the Ionosphere. This layer extends of 62 miles(100 km) to 190 miles(300 km) of the Earth's surface. The last layer is called the Exosphere, the outermost layer of the atmosphere that extends from 1000km above the ground. In this layer, gases get thinner and thinner and drift off into space.

How many feet is it to space? There are many levels of atmosphere around the Earth as you move from ground into space, 5 levels as we have modeled them. The first is the Troposphere, which reaches out ~ 20,000 feet - 65,600 feet (6-20 km) from ground level. Mt. Everest is about this high. Most planes, etc remain in this level. The second is the Stratosphere, which reaches out ~ 164,000 feet (50 km). Weather balloons are able to reach this high into atmosphere. The third is the Mesosphere, which reaches ~ 279,000 feet (85 km) from ground level. This is generally where meteors burn up and can be seen from the ground.

Intro to Space Activities Orbits of the Earth. Low Earth Orbit (LEO) is commonly accepted as between 124 and 1,240 miles above the Earth’s surface. Spacecraft in LEO make one complete revolution of the Earth in about 90 minutes (the “orbital period”). The International Space Station (ISS) orbits between 198.6 and 215.5 miles above the Earth’s surface. The Space Shuttle and Hubble Space Telescope also operate in this region. The proximity to the Earth’s surface provides a high level of detail and ability to detect distinct objects (known as “spatial resolution”).

Exosphere The upper boundary of the exosphere can be defined as the distance at which the influence of solar radiation pressure on atomic hydrogen exceeds that of Earth's gravitational pull. This happens at half the distance to the Moon (the average distance between Earth and the Moon is 384,400 kilometres (238,900 mi)).

WHAT IS THE ATMOSPHERE MADE OF? About 50% of the mass of the atmosphere is located below an altitude of about 18,000 feet (5.6 km). About 90% of the atmosphere's mass is below an altitude of 52,000 feet (16 km). Almost all of the atmosphere's mass (99.99997%) is located below 330,000 feet or 62 miles (100 km). That altitude of 100 km is considered by many people to be the edge of space-the boundary between the Earth's atmosphere and outer space.

The Troposphere The troposphere is the lowest layer of Earth's atmosphere. The troposphere starts at Earth's surface and goes up to a height of 7 to 20 km (4 to 12 miles, or 23,000 to 65,000 feet) above sea level. Most of the mass (about 75-80%) of the atmosphere is in the troposphere. Almost all weather occurs within this layer.

- Figure 2-10. - Layers of the earth's atmosphere. The troposphere is the portion of the Earth's atmosphere that extends from the surface of the Earth to a height of about 3.7 miles (6 km) at the North Pole or the South Pole and 11.2 miles (18 km) at the equator. Virtually all weather phenomena take place in the troposphere.

How many miles up is space? Best Answer: NASA says 62 miles (100 km) is where space starts. If you go that high, you're an astronaut. It's arbitrary. The atmosphere doesn't end. It just gets thinner and thinner. Some people talk about Earth's atmosphere at 700 or 800 miles.

Outer space There is no firm boundary where outer space starts. However the Kármán line, at an altitude of 100 km (62 mi) above sea level, is conventionally used as the start of outer space in space treaties and for aerospace records keeping.

Earth Earth's atmosphere has no definite boundary, slowly becoming thinner and fading into outer space. Three-quarters of the atmosphere's mass is contained within the first 11 km of the surface. This lowest layer is called the troposphere. Energy from the Sun heats this layer, and the surface below, causing expansion of the air.

How High is Space? The edge of space. Credit: NASA. This was the altitude that airplane control surfaces could no longer be used, and corresponded to roughly 50 miles, or 81 kilometers. Any NASA test pilot or astronaut who crosses this altitude is awarded their astronaut wings.

What height does the International Space Station orbit around the Earth? What height does the International Space Station orbit around the Earth? The International Space Station is maintained in a near circular orbit with a minimum mean altitude of 278 km (173 mi) and a maximum of 460 km (286 mi). Atmospheric drag gradu…ally slows the station down and it moves closer to earth. The station must be periodically re-boosted.

- The thermosphere lies above the mesosphere, starting at about 50 miles. above sea level. This layer is often called the “upper atmosphere.” Any person trav-. eling at an altitude of more than 50 miles above sea level is considered an astronaut. Space shuttles and some satellites orbit the Earth within this layer.

Layers of the Atmosphere This is the outermost layer of the atmosphere. It extends from the top of the thermosphere to 6,200 miles (10,000 km) above the earth. In this layer, atoms and molecules escape into space and satellites orbit the earth. At the bottom of the exosphere is the thermopause located around 375 miles (600 km) above the earth. Between about 53 miles (85 km) and 375 miles (600 km) lies the thermosphere. This layer is known as the upper atmosphere. While still extremely thin, the gases of the thermosphere become increasingly more dense as one descends toward the earth.

Atmosphere of Earth The troposphere is the lowest layer of Earth's atmosphere. It extends from Earth's surface to an average height of about 12 km, although this altitude actually varies from about 9 km (30,000 ft) at the poles to 17 km (56,000 ft) at the equator, with some variation due to weather.he atmosphere of Earth is the layer of gases surrounding the planet Earth that is retained by Earth's gravity.

How Many Miles Is It From Earth to Space? How many miles do you have to go up to get out of the Earth's atmosphere and into space? Credit: David Bases Photo Library Getty Images. 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.

Layers of the Atmosphere The Exosphere is the outermost layer of the atmosphere. It extends from the thermopause - the transition boundary which separates the exosphere from the thermosphere below - to 6,200 miles (10,000 km) above the earth. In this layer, atoms and molecules escape into space and satellites orbit the earth.

The atmosphere becomes thinner and thinner with increasing altitude, with no definite boundary between the atmosphere and outer space.

Where does âouter spaceâ begin? In the crisp early morning of June 21, the privately developed rocket plane SpaceShipOne shot itself to the edge of space. Starting from 50,000 feet, the craft took slightly more than a minute to breach the final frontier, 62 miles (100 kilometers) above the saffron sands of California’s Mojave Desert. Space, according to the rules of this game, begins 100 kilometers up. That’s obviously an arbitrary definition.
