| In the shed on the left is Orion, which is a two-stage rocket for deep penetration into the exosphere. |
| The loss rate of molecules through the exosphere is critical in determining whether Earth or any other planetary body retains an atmosphere. |
| And the successive stratospheric and mesospheric layers, until reaching the exosphere in interplanetary space. |
| With around three hundred plus kilometers to go, we'll be in the exosphere, aka space, in no time at all. |
| The spectacular auroras form in the regions of the exosphere, the bottom of which is found at 500 kilometres above the Earth's surface. |
| He considered the initiation of an earth-magnetic field experiment to detect hydromagnetic waves in the upper ionosphere and exosphere. |
