00:00:00.000 --> 00:00:08.000
Intro music.

00:00:08.000 --> 00:00:14.000
Aura will lift off from Vandenberg Air Force base in California aboard a Delta II launch vehicle.

00:00:14.000 --> 00:00:22.000
The spacecraft is designed to fly at a near-polar orbit, at 98.2 degrees of inclination.

00:00:22.000 --> 00:00:30.000
A polar orbit is one in which the spacecraft flies in a north-south path as the Earth turns below it.

00:00:30.000 --> 00:00:33.000
This will put Aura in position to join the A-Train,

00:00:33.000 --> 00:00:40.000
a group of satellites that work together to provide a complete picture of environmental change on Earth.

00:00:40.000 --> 00:00:45.000
There are four major scientific instruments aboard Aura.

00:00:45.000 --> 00:00:51.000
All of them are designed to study the chemistry of the atmosphere, but they all have different ways of doing it.

00:00:51.000 --> 00:01:00.000
Together, Aura's cutting edge hardware will provide us with the most comprehensive picture of the air we breathe.

00:01:00.000 --> 00:01:05.000
