The turbopause marks the altitude in the Earth s atmosphere below which turbulence turbulent mixing dominates. The region below the turbopause is known as the homosphere , where the chemical constituents are well mixed and display identical height distributions in other words, the chemical composition of the atmosphere remains constant in this region for chemical species which have long mean residence times. Highly reactive chemicals tend to exhibit great concentration variability throughout the atmosphere, whereas unreactive species will exhibit more homogeneous concentrations. The region above the turbopause is the heterosphere , where diffusion molecular diffusion dominates and the chemical composition of the atmosphere varies according to chemical species. The turbopause lies near the mesopause , at the intersection of the mesosphere and the thermosphere , at an altitude of roughly 100 km.

The Jacchia Reference Atmosphere is an atmospheric model that define values for atmospheric temperature, density, pressure and other properties at altitudes from 90 to 2500 km. Unlike the more common US Standard Atmosphere and related models, the Jacchia model includes latitudinal, seasonal, geomagnetic, and solar effects, but must be supplemented with another model at lower altitudes. The model, first published in 1970 and updated in 1971 and 1977, is based on spacecraft drag data, and is primarily used in spacecraft modeling and related fields. A common assumption while using the Jacchia Model is that the atmosphere rotates with the Earth as a rigid body.

Unreferenced date November 2006 The thermopause is the Earth s atmosphere atmospheric boundary of Earth s energy system, located at the top of the thermosphere . Below this, the atmosphere is defined to be active on the insolation received, due to the increased presence of heavier gases such as monoatomic oxygen. The solar constant is thus expressed at the thermopause. Beyond above this, the exosphere describes the thinnest remainder of atmospheric particles with large mean free path, mostly hydrogen and helium. The exact altitude varies by the energy inputs of location, time of day, solar flux, season, etc. and can be between 500 1000 km high at a given place and time because of these. A South Atlantic Anomaly portion of the magnetosphere dips below this layer as well. Although these are all named layers of the atmosphere, the pressure is so negligible that the chiefly used definitions of outer space are actually below this altitude. Orbiting satellites do not experience significant atmospheric heating, but their orbits do decay over time, depending on orbit altitude. Space missions such as the International space station ISS , space shuttle , and Soyuz programme Soyuz operate under this layer.

The first CIRA appeared 1961 as CIRA1961 . It was a set of tables reconsidered year for year by the Task group on the CIRA originally chaired by Hildegard Kallmann Bijl . Today Presently CIRA 1986 covers the height range up to 120 km as a set of tables. In the thermosphere, above about 100 km, CIRA 86 is identical to the more complicated NASA MSIS 86 model.

This article is about the atmospheric mesosphere, for the Earth s mantle see Mesosphere mantle . The mesosphere IPA en m so sf r pron from the Greek language Greek words mesos middle and sphaira ball is the layer of the Earth s atmosphere that is directly above the stratosphere and directly below the thermosphere . In the mesosphere temperature decreases with increasing height. The upper boundary of the mesosphere is the mesopause, which can be the coldest naturally occurring place on Earth with temperatures below 130 K. The exact upper and lower boundaries of the mesosphere vary with latitude and with season, but the lower boundary of the mesosphere is usually located at heights of about 50 km above the Earth s surface and the mesopause is usually at heights near 100 km, except at middle and high latitudes in summer where it descends to heights of about 85 km. The stratosphere, mesosphere and lowest part of the thermosphere are collectively referred to as the middle atmosphere , which spans heights from approximately 10 to 100 km. The mesopause , at an altitude of convert 80 90 km mi abbr on , separates the mesosphere from the thermosphere &mdash the second outermost layer of the Earth s atmosphere.

File Kittinger jump.jpg thumb Kittinger leaps from his helium balloon at aprox. 102,000 ft. Like sky diving , Space diving refers to the act of jumping from a plane, balloon, or spacecraft in outer space and falling to Earth s atmosphere before parachuting to a landing. Depending on one s definition of space , the only historical case of a human intentionally space diving from the stratosphere is Joseph Kittinger , who jumped from a helium balloon at the height of 100,000 feet approximately 32 kilometers ref http www.truthorfiction.com rumors k kittenger free fall.htm ref . Higher jumps from mesosphere or thermosphere have yet to be successfully performed, though Orbital Outfitters ref http www.orbitaloutfitters.com SpaceSuits.html ref is working to create a suit that will enable safe space diving. Space diving from beyond the stratosphere has been imagined in various fictional contexts, including Star Trek film Star Trek and the novel Starship Troopers . Challenges to Safe Space Diving There are several technical requirements and challenges to the possibility of space jumping. The space diver suit would have to protect against hostile temperatures, pressures, and lack of oxygen. At the heights involved, low pressure would cause the bends within the space diver. This would turn the blood to gas and would be fatal. Furthermore, depending on the weight of the diver, the Atmospheric reentry reentry suit would likely have to be armored to survive the heat of reentry. While there is no fire layer of atmosphere, the speed of orbit is in the thousands of kilometers per hour. To go from this speed into the atmosphere would cause friction on the air, and could cause the diver to heat up to 400 degrees Fahrenheit. Gravity is also a challenge. As the diver presses through the thin atmosphere to the thicker air below, he could slow at such rates that he experiences negative G forces from 2 8, possibly contributing to black outs or other pressure related complications.
