What has been learned from Landsat images?

Since its first satellite went up in the summer of 1972 Landsat has been looking at our planet. The view of Earth that this 40-year satellite program has recorded allows scientists to see in ways they never imagined how the Earth’s surface has transformed over time.

What is Terra mission?

Terra Mission. Terra Mission (EOS/AM-1) Terra (formerly known as EOS/AM-1) is a joint Earth observing mission within NASA’s ESE (Earth Science Enterprise) program between the United States Japan and Canada.

Why is Earth referred to as Terra?

From the Latin terra – with origins in the Proto-Indo-European ters- meaning “dry” – the Romance languages derived their word for Earth including the French La Terre Italian La Terra and Spanish La Tierra.

How do Earth observation satellites work?

The satellite on this orbit passes by a certain place of the Earth’s surface at the same local solar time (the orbit plane keeps a constant solar angle) so the satellite observes the same sun light reflection from the Earth’s surface.

What are some of the capabilities for the satellite Suomi NPP satellite?

NPP’s advanced imagery of clouds ocean surface land features and other physical parameters is key data for civilian and DoD forecasters.

How do satellites collect images?

Satellites use different kinds of sensors to collect electromagnetic radiation reflected from the Earth. Passive sensors collect radiation which the Sun emits and the Earth reflects and don’t require energy. Active sensors emit radiation themselves and analyze it after it is reflected back from the Earth.
