In 2009, measurements of the direction and speed of ions in the atmosphere were made from a sounding rocket. The altitude of above Earth was the midpoint for charged particles transitioning from the gentle winds of the Earth's atmosphere to the more extreme flows of outer space. The latter can reach velocities well over .
