The gap in magnetic field, protecting the planet from solar wind and radiation, allows them to gain direct access to the Earth’s atmosphere in polar latitudes.

The phenomenon was able to be recorded at those moments when the Sun is in its highest point, writes NASA.
Radio and GPS signals behave strangely when they pass through this part of the sky, and spacecraftthat pass through this region slow down.

So, at the height about 402 km Above Earth, spaceships feel more drag, as if they collided with a speed bump, physicists say.
It’s because the air in this place noticeably denser than others in spacecraft orbits around the Earth.
By studying the phenomenon itself, scientists hope to better anticipate changes in trajectories of spaceships.

However, the process is not easy, since experiments can only be carried out an hour or two a day.
“This is comparable to how we thread a needle,” – explain the physicists.
We will remind, earlier it was reported that the astronauts of the ISS could not go into outer space due to the threat overboard.
