Scientists Pinpoint The ‘Edge Of Space’
ScienceDaily — Where does space begin? Scientists at the University of Calgary have created a new instrument that is able to track the transition between the relatively gentle winds of Earth’s atmosphere and the more violent flows of charged particles in space – flows that can reach speeds well over 1000 km/hr. And they have accomplished this in unprecedented detail.
Data received from the U of C-designed instrument sent to space on a NASA launch from Alaska about two years ago was able to help pinpoint the so-called edge of space: the boundary between the Earth’s atmosphere and outer space.
With that data, U of C scientists confirmed that space begins 118 km above Earth and the results were published this week in the Journal of Geophysical Research.
