The exosphere is the uppermost layer of the atmosphere. In the exosphere, an upward travelling molecule can escape to space if it is moving fast enough to attain escape velocity; otherwise it will be pulled back to the celestial body by gra...

The dayside surface temperature is assumed to be about 540 K. Since Mercury is close to the Sun, solar heating of the surface implies that thermal desorption will also be an important source of exospheric Na. ... Exosphere Simulation...

We present a Monte-Carlo model of sodium and calcium in Mercury's exosphere. The important source mechanisms are sputtering by solar wind ions, photon-stimulated desorption, and micrometeoroid impact vaporization.

We present the extension to the thermosphere of a Martian general circulation model, the first able to self‐consistently study the whole Martian atmosphere from the surface to the exosphere. We describe the parameterizations developed to include physical processes important for thermospheric altitudes.

The exosphere is the outermost layer of the atmosphere, and extends to 40,000 miles above the earth. It is here that molecules escape from the atmosphere without colliding with other molecules. ... Extending through both the thermosphere and exosphere is the ionosphere, named for its concentrated layers of ions,

The atmosphere is made up of several layers: the troposphere, stratosphere, mesosphere, ionosphere, and exosphere. Closest to Earth is the troposphere. Most of the clouds you see in the sky are found in the troposphere, and this is the layer of the atmosphere we associate with weather.

The exosphere plays an important role in the plasma budget of the Earth's inner magnetosphere as a "sink" for ring current charged particles, because charge exchange with exospheric neutral hydrogen is the principal mechanism by which the ring current loses plasma and can return to its "ground state" following...
