Layers of the Earth's atmosphere. The troposphere is the first layer above the surface and contains half of the Earth's atmosphere. Weather occurs in this layer. Many jet aircraft fly in the stratosphere because it is very stable. The stratosphere contains the ozone layer.
Meteors burn up in the mesosphere.
Aurorae occur in the lower thermosphere. The thermosphere is also where the space shuttle orbits. Some satellites, like the Compton Gamma Ray Observatory , have onboard jets to compensate for orbit decay. When perigee gets too low, they can nudge themselves back to a higher altitude. Other LEO satellites need a little help.
