The Aeronomy of Ice in the Mesosphere (AIM) satellite mission is exploring Polar Mesospheric Clouds (PMCs), also called noctilucent clouds, to find out why they form and why they are changing.
The AIM mission has been extended by NASA through the end of FY12. During this time the instruments will monitor noctilucent clouds to better understand their variability and possible connection to climate change. Individual instrument data collection status, as well as spacecraft and instrument health, will be monitored throughout the life of the mission and reported periodically on this earth
Hope this helps :)
The mesosphere begins about 30 to 50 miles above the earth's surface and ends about 60 miles above the surface.
about 300 km to 500 km (height)
80 Kilometers
560 miles
7 miles!

Stratosphere by great usama
The focus is the point in the earths crust where the earthquake originates and the epicentre is the point in the earths surface directly above the focus.
The point directly above the focus of an earthquake is called the epicenter. It is usually the point of greatest destruction.

Mesosphere
No, satellite orbits are above the mesosphere in the thermosphere, which extends from about 100 to 600 km above the Earth's surface.
troposphere
The stratosphere is one of the layers of the Earth's Atmosphere. It extends 10km to 20km above the planet surface and is located above the troposphere and below the mesosphere.
mesosphere
The mesosphere is the layer of Earth's atmosphere above the stratosphere and below the thermosphere. It extends from 50 kilometers to 100 kilometers above sea level. The name mesphere also, though less often, refers to a layer of Earth's mantle between the asthenosphere and the outer core. It extends from 660 kilometers to 2,700 kilometers below the surface.

The zone - or layer - that sits above the stratosphere is the mesosphere. This layer extends from about 50 km (or 31 miles) to around 85 km (or 53 miles) above the surface of the Earth. The mesosphere is where meteors will burn up as they enter the atmosphere. The temperature of this layer decreases with height.
There are many layers to the atmosphere. The layer that extends 50-85 kilometers is called the mesosphere. The top part of the mesosphere is the coldest part of the atmosphere.
It extends to 600-700 km above earth's surface
Thermosphere - extends from 80 km above the Earth Mesosphere - extends from 50 - 80 km above the Earth Stratosphere - extends from 15 - 50 above the Earth Troposphere - closest to the Earth
Height above earths surface is called elevation
