NASA will organize a two-spacecraft mission with the primary goal of studying the northern lights and its effects on Earth. 

The first rocket will be launched by the space agency over 100 miles above Earth (~ 160 km). This will give scientists the opportunity to watch the wind in a neutral atmosphere.

Hoping that everything goes according to plan and the first rocket has reached its goal, NASA will launch a second rocket, this time above, over 125 miles above Earth (~ 200 km). The objective of the second one is completely different from that of the first.

This second rocket will have the main objective of measuring the temperature and density of plasma in the aurora (especially since the northern lights are a fairly important source of heat).

A rather strange phenomenon is occurring in the northern lights, where the energy of the sun's rays separates the electrons from the atoms and transforms the gases into plasma.

The point where the gas becomes plasma is a gray area where the two forms of matter mix, and occasionally winds or magnetic disturbances will cause the particles to collide in strange ways. This border area is facing constant friction, according to NASA.

Another reason why NASA wants to study the northern lights is precisely because of their formation. Auroras are formed when electrons from space pour into our atmosphere, "igniting" neutral particles by heat and friction when the two collide.

Thus, scientists believe that this is an important thing to understand how much energy is released into the upper atmosphere.
