how far is space from earth surface

That’s about the height of the orbit of the International Space Station (ISS). 7 Answers. Just wanted to be clear I wasn’t disputing Fraser’s number. Chris - Let’s take it to it’s logical conclusion; the reason that Pluto is 6 billion kilometres from where we are here on Earth and it’s still orbiting the Sun is because the Sun’s gravity is hanging onto Pluto, even though it’s that far away. The U.S. Supreme Court: Who Are the Nine Justices on the Bench Today? The International Space Station also orbits in this layer, between 320 and 380 km (200 and 240 mi), and needs to be constantly boosted because friction with the atmosphere still occurs. has no beginning and end). Theories of Where Outer Space Begins. In response, then-President Dwight D. Eisenhower signed the National Aeronautics and Space Act on July 29th, 1958, officially establishing NASA. 1. National Advisory Committee for Aeronautics, Space Debris Illustrated: The Problem in Pictures, NASA Reveals Mysteries of Interstellar Space, Creative Commons Attribution 4.0 International License. But in truth, Earth’s atmosphere is made up of five main layers – the Troposphere, the Stratosphere, the Mesosphere, the Thermosphere, and the Exosphere – the latter of which extend pretty far out into space. Favorite Answer. I’m not saying he’s “wrong,” at all, just saying that the actual exospheric edge is pretty fuzzy: no one can really tell whether it’s space or exosphere a thousand km or more to either side of that point without sampling the few particles they find out there to determine their origin (space vs. Earth)…, …Which at the end of the day makes 10,000 km just as good an estimate as any, and not worth arguing over. Glenn completed three orbits of planet Earth, and three more orbital flights were made, culminating in L. Gordon Cooper’s 22-orbit flight aboard Faith 7, which flew on May 15th and 16th, 1963.

By 1959, this competition resulted in the creation of the Soviet Vostok program and NASA’s Project Mercury. This is the point where the Space Shuttle would begin using air to maneuver instead of thrusters. But beyond that, there is no meteorological phenomena in this region. By the same token, space is often defined as beginning at the lowest altitude at which satellites can maintain orbits for a reasonable time – which is approximately 160 kilometers (100 miles) above the surface. But whatever the exact definition is, if you can get above 100 kilometers, you have definitely earned your astronaut wings! 5-9 miles from the surface to space. The International Space Station also orbits in this layer, between 320 and 380 km (200 and 240 mi), and needs to be constantly boosted because friction with the atmosphere still occurs. These varying definitions are complicated when one takes the definition of the word “atmosphere” into account. This distance can change, however, and has varied from 205 miles (330 km) to a planned maximum of 248 miles (400 km). Any such ‘edge’ is likely to be highly dynamic, asymmetric, heterogeneous in composition & extend some distance beyond the outer Van Allen belt, depending on solar conditions & if it exists at all. That translates to 6 microbars, where 1 bar is the pressure at Earth's surface. How Many Miles Is It From Earth to Space. The orange layer is the troposphere, the white layer is the stratosphere and the blue layer the mesosphere. So it is quite literally all around us. A body is projected out with thrice this speed. The part of the atmosphere which is barely distinguishable from the vacuum of space (exosphere) is what’s responsible for the eventual de-orbiting of anything in LEO lacking a working thruster out to a couple-few thousand km (takes longer the further out one goes & depends a lot on solar activity, hence my super-specific altitude reference!). So the atmosphere will have dropped off to 37% raised to the twelfth power, or about 160,000 times thinner that at the suface. (Like water/air, but air/space). Designed to send a man into space using existing rockets, the program quickly adopted the concept of launching ballistic capsules into orbit. Post was not sent - check your email addresses! Ignore the presence of the sun and other planets. Night and day are about 120 earth days in length so that's a pretty slow axial rotation and a very slow loss of surface heat during the planet's night. Most people consider space to simply be the region above the Earth's atmosphere. The Karman Line is an imaginary boundary that lies 100 kilometers above Earth and is widely considered the boundary between the outer space and Earth’s atmosphere. This definition is accepted by the Fédération Aéronautique Internationale (FAI), which is an international standard setting and record-keeping body for aeronautics and astronautics. Other conditions such as for an infinite size, the universe would have to have expanded at an infinite rate since the big bang. This ended in 1979 with the downing of the station over the Indian Ocean and parts of southern Australia. According to data collected by the University of Calgary, space begins and the Earth's atmosphere ends at 73 miles above the Earth's surface. Some scientists argue that space does not begin until 13 million miles out; this is point where Earth's gravity does not have any influence on an object. The escape speed of a projectile on the earth's surface is 1 1. There is no firm upper altitude designated for the exosphere. Place the tennis ball there. Google Tag Manager Jan 06, 12:41 AM EST On June 16th, 1963, Valentina Tereshkova was sent into orbit aboard the Vostok 6 craft (which was the final Vostok mission), and thus became the first woman to go into space. 1 decade ago How far away is the International Space Station from the earth's surface? First, imagine blasting off and being about 200 miles (300 km) above Earth’s surface. A COVID-19 Prophecy: Did Nostradamus Have a Prediction About This Apocalyptic Year? How far is the moon e 1 mean sea level gps and the geoid this map lets you plug in your address china is now positioned to dominate the How Far Is The Moon EWatching The World Go ByTracking Solar FlaresSuper Earth Revealed In Discovery Of New Pla TimeNasa Do You Know Where Your E… Read More » During the advent of the Space Age and the ability to use orbital satellites to measure the planet from space, this was finally confirmed. There is no clear boundary between Earth's atmosphere and space as the density of the atmosphere gradually decreases as the altitude increases. However, other countries and agencies have a differing opinion on where space begins. This began on Jan. 24th, 2001, when a Russian Progress cargo ship docked with the station and pushed it out of orbit. We have written many interesting articles about space here at Universe Today. Once the “Race to the Moon” ended with the successful landing of Apollo 11 (followed by several more Apollo missions), the focus began to shift to establishing a permanent presence in space. Anonymous. Answer for question: Your name: Answers. For example, the ISS orbits roughly 400 km above the Earth, which is only 400/6378 $\sim$ 6.3 % farther from the center of the Earth than the surface. The flattened spherical nature of Earth is reflected in terms of its equatorial and meridional circumference. Raymond. Relevance. However, other countries and agencies have a differing opinion on where space begins. The Earth's atmosphere gradually grows thinner with increasing distance from the surface of the planet. This work is licensed under a Creative Commons Attribution 4.0 International License. But thanks to decades of space exploration and launches, we have managed to come up with a working definition. This was the altitude that airplane control surfaces could no longer be used, and corresponded to roughly 81 kilometers (50 miles) above the Earth’s surface. With space at 60 miles, that's 12 scale heights (60/5 = 12). 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. 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. Now the atmosphere on Venus is very thick, masses of that lovely CO2, and surface pressure is about 90 times that of earth (9.2MPa). The speed necessary to reach this situation is about 28,200 kilometers per hour (17,500 miles per hour) and this is the speed that the Space Shuttle must attain to continue to fall around Earth (remain in orbit) at an altitude of 300 kilometers (186 miles). Combining NASA’s Space Station Freedom project with the Soviet/Russian Mir-2 station, the European Columbus station, and the Japanese Kibo laboratory module, the project also built on the Russian-American Shuttle-Mir missions (1995-1998). Positive: 100 %. 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. But, there is no tangible boundary because the atmosphere gradually thins with increasing altitude. It maintains an orbit with an average altitude of 400 kilometres (250 mi) by means of reboost manoeuvres using the engines of the Zvezda Service Module or visiting spacecraft. Look up at the night sky, and what do you see? It is the largest artificial object in space and the largest satellite in low Earth orbit, regularly visible to the naked eye from Earth's surface. Answer Save. 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. 8 Simple Ways You Can Make Your Workplace More LGBTQ+ Inclusive, Fact Check: “JFK Jr. Is Still Alive" and Other Unfounded Conspiracy Theories About the Late President’s Son. First, imagine blasting off and being about 200 miles (300 km) above Earth’s surface. In addition, in all three definitions, the measurements involved are beyond anything that we humans are accustomed to dealing with on a regular basis. However, technical failures and a failure in one rocket’s second stage boosters caused the first three attempts after Salyut 1 to fail or result in the station’s orbits decaying after a short period.

How far up from the surface of Earth is space? 1 decade ago. Lowest altitude of Aurora Borealis 80km. On April 12th, 1961, Soviet cosmonaut Yuri Gagarin was launched aboard the Vostok 1 spacecraft from the Baikonur Cosmodrome, and thus became the fist man to go into space (beating American Alan Shepard by just a few weeks). That’s about the height of the orbit of the International Space Station (ISS). No discontinuities. Basketball 2. Hi d s r rao, Most of the time, the International Space Station (ISS) is orbiting the Earth at an altitude of approximately 220 miles (354 km), which places it in low Earth orbit (LEO). The disadvantage is that there will be some drag from the atmosphere, which extends into this region of space … Astronauts aboard are weightless because their space … ”………Some scientists believe that space extends infinitely in all directions,……….” sums up the dimensions of the space/universe. It's not as far as you'd expect (or at least as far as I expected)... at a little over 50 miles obove the surface of the earth is considered the end of the atmosphere... but literally, the whole earth is part of space, so we're all "in" space right now. Despite the harsh environment, several life forms have been found that can withstand extreme space conditions for extended periods. As you can probably imagine, with such a subjective definition, people tend to disagree on exactly where space begins. As a gas’ temperature increases, the space between molecules & atoms typically gets larger… and that’s the key: “space” between molecules/atoms is what makes it a “gas,” instead of a liquid or a solid. As satellites get closer to Earth, the pull of gravity gets stronger, and the satellite … Any NASA test pilot or astronaut who crosses this altitude is awarded their astronaut wings. However, by 1974, the Russians managed to successfully deploy Salyut 4, followed by three more stations that would remain in orbit for periods of between one and nine years. Between 1972 and 1991, they attempted to orbit seven separate stations. Another important distinction when discussing space is the difference between that which lies between planets (interplanetary space) and that which lies between star systems (interstellar space) in our galaxy. Starting above the 'space' limit but a bit before LEO, the inner Van Allen Belts, which magnetically shield the Earth's surface from high energy particles, extend from 100km (62 miles, 33,000 feet) up to 10,000km (6,200 mil, 3.3 million feet). There are multiple answers, they are arbitrary, and it doesn’t really matter. By 1993, NASA began collaborating with the Russians, the ESA and the Japan Aerospace Exploration Agency (JAXA) to create the International Space Station (ISS). In Low Earth Orbit (i.e. a region occupied centrally by a planet, star or galaxy. things orbiting Earth), they are in nearly the same gravitational field as we are. Have We Really Just Seen The Birth Of A Black Hole? For more information, check out NASA Reveals Mysteries of Interstellar Space and this list of Deep Space Missions. The Earth is a sphere with a roughly 8000 mile diameter; the thickness of the atmosphere is about 60 miles. 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. Favourite answer. This altitude was later adopted as the Karman Line by the World Air Sports Federation (Fédération Aéronautique Internationale, FAI). During deployment, Skylab suffered severe damage, losing its thermal protection and one of its solar panels. Earth orbits the sun 100,000 times closer than the Oort Cloud, at an average of 92,955,807 miles (149,597,870 km). 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. The outermost layer, known as the exosphere, extends out to an altitude of 10,000 km (6214 mi) above the planet. 1 decade ago . How Far Down is the Center of the Earth? . The low density of matter in outer space means that electromagnetic radiation can travel great distances without being scattered: the mean free path of a photon in intergalactic space is … It doesn't work so that enough far away from the Earth, there won't be gravity any more. In the ensuing decades, both NASA and Soviets began to develop more complex, long-range crewed spacecraft. The first official definition of space came from the National Advisory Committee for Aeronautics (the predecessor to NASA), who decided on the point where atmospheric pressure was less than one pound per square foot. 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. In other words, there’s a reason they call it space – there’s just so much of it! By 1986, the Soviets once again took the lead in the creation of space stations with the deployment of Mir. In time, it evolved into a station consisting of multiple modules and several ports for crewed Soyuz spacecraft and Progress cargo spaceships. @Zousteen: There isn’t a clear boundary between gas & vacuum as there is between liquid & gas (the primary reason for the latter being liquid surface tension) or liquid & solid (molecular lattices, crystalline structure, etc.). Meanwhile, NASA took over Project Mercury from the US Air Force and began developing their own crewed mission concept. Lv 7. Along with numerous unmanned tests, and a few using dogs, six Soviet pilots were selected by 1960 to be the first men to go into space. Space shuttle launch pad tower structure: 155 feet: Atlas-5 rocket, Delta-4 rocket, erect on launch pad: 151 feet: Statue of Liberty: 4-7 feet: Human beings: 0 feet: Fog, a low stratus cloud with base on the ground: 0 feet: Surface of Earth – Sea Level the view from here –3963 miles: Center of Earth from surface Tennis ball 3. The thermosphere extends between the altitudes of 85 and 1,000 kilometers (53 and 621 miles). At 1 AU, Earth receives 1 unit of sunlight; what we generally might associate with a bright sunny day at noon. 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. So, between them and the space ship, there’s no acceleration. Relationship Between Moon Earth And Sun . Greater velocity would put it into a stable orbit, like that of the Moon, or direct it away from Earth altogether. There are galaxies far, far away but ... reach Earth's surface. The low Earth orbit zone extends out to about 1,243 miles (2,000 km) from the surface of the planet. According to Newton the force of gravity falls off as the square the distance of the bodies that are attracted to each other. The tennis ball is the moon. i.e. The ISS program is expected to continue until at least 2020, but may be extended until 2028 or possibly longer, depending on the budget environment. It doesn't work so that enough far away from the Earth, there won't be gravity any more. How far up from the surface of Earth is space? While this is high enough to see that the Earth is round (believe me, it is), we are still just barely skimming the surface when you consider that the diameter of the Earth … On May 5th, 1961, astronaut Alan Shepard became the first American in space aboard the Freedom 7 mission. Space, glittering and gleaming in all its glory. The moon's orbit around Earth is elliptical. Answer #1 | 30/03 2016 18:31 **Officially** it's 100km - 62.2 miles. Images from space probes, such as Voyager 1 and 2, showed much higher details of planets and moons in the solar system than Earth-bound telescopes could see. Earth’s gravity does a fair job keeping most of our air in the troposphere, and from there the whole atmosphere generally describes a pressure curve that decreases with altitude — swiftly, & then more gradually with height, approaching but never quite reaching zero density. However, the Earth's atmosphere does not stop abruptly. Military jets (from th Is there a noticeble jump between surface and space that indicates some kind of sudden drag reduction? 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.
