The latest polar-orbiting satellite in the TIROS-N fleet is set for launch from Vandenberg Air Force Base in California, aboard a Boeing Delta II rocket.

00:00:18.000 --> 00:00:26.000
Dubbed NOAA-N, the satellite was jointly developed by NASA and the National Oceanic and Atmospheric Administration,

00:00:26.000 --> 00:00:30.000
known as NOAA, to expand environmental observations of Earth.

00:00:30.000 --> 00:00:40.000
TIROS, or Television Infrared Observation Satellites, have been observing our planet from the perspective of a polar orbit since 1978.

00:00:40.000 --> 00:00:47.000
"NOAA-N is a single satellite, but it's part of a constellation of satellites that are in the polar-orbiting system,

00:00:47.000 --> 00:00:53.000
and NOAA uses two of these satellites as their main operational satellites.

00:00:53.000 --> 00:01:00.000
And data from two of these satellites cover the entire globe, the whole Earth, at least four times a day."

00:01:00.000 --> 00:01:06.000
These satellites provide NOAA constant data about our environment and weather,

00:01:06.000 --> 00:01:10.000
and make other observations like cloud cover and sea surface temperature.

00:01:10.000 --> 00:01:23.000
The launch of NOAA-N will help continue this flow of vital data about the surface and atmosphere of our planet.
