too much time was taken to collect the data

it is too early to say whether or not the mission was a success

despite the complexity of the mission, the team worked accurately and efficiently

more money is needed in order to invent anti-gravity machines

it aids in measuring the upper atmosphere's expansion 

it determines the temperature around the aurora

it corrects the satellite's orbital motion

it can ultimately help preserve energy in the future

The Invisible Aurora contains the currents and voltage, which propel Aurora Borealis

The Visible Aurora is just as active as the Invisible Aurora

most people think of the Invisible Aurora when they imagine Aurora Borealis

Arcs and explosions characterize the Invisible Aurora

a force acting opposite to the relative motion of a satellite

another term that defines electric currents

energy manufactured by the orbital motion of the satellite

the temperature around the satellite

it also turns up along the Sun's magnetic field

colors of the aurora depend on beam energy, oxygen and nitrogen

high altitude oxygen creates the most common aurora

it is the result of Earth's gaseous particles colliding in the atmosphere
