Terra | The EOS Flagship Terra: The EOS Flagship Terra explores the connections between Earth’s atmosphere, land, snow and ice, ocean, and energy balance to understand Earth’s climate and to map the impact of human activity and natural disasters on communities and ecosystems
About Terra Current systems issues: None Processed Terra data are available through several NASA data centers Current life expectancy: Terra has far exceeded its design life and has a strong chance of operating successfully into the early 2020s Terra began drifting in February of 2020 Read more about Terra’s drifting or see key dates below Key dates
Mission - Terra Terra observations reveal humanity’s impact on the planet and provide crucial data about natural hazards like fire and volcanoes See Terra science Terra is an international mission carrying instruments from the United States, Japan, and Canada

MODIS - Terra With its sweeping 2,330-km-wide viewing swath, MODIS sees every point on our world every 1-2 days in 36 discrete spectral bands Consequently, MODIS tracks a wider array of the earth’s vital signs than any other Terra sensor For instance, the sensor measures the percent of the planet’s surface that is covered by clouds almost every day
Terra Instruments Terra collects data about the Earth’s bio-geochemical and energy systems using five sensors that observe the atmosphere, land surface, oceans, snow and ice, and energy budget Each sensor has unique features that enable scientists to meet a wide range of science objectives The five Terra onboard
MISR - Terra Most satellite instruments look only straight down, or toward the edge of the planet To fully understand Earth’s climate, and to determine how it may be changing, we need to know the amount of sunlight that is scattered in different directions under natural conditions MISR is a new type of instrument designed to address this need — it views the Earth with cameras pointed at nine
MOPITT - Terra Measurement of Pollution in the Troposphere Widespread fires in western Africa release carbon monoxide into the atmosphere (red) in February 2004 Measurement of Pollution in the Troposphere (MOPITT) is an instrument designed to enhance our knowledge of the lower atmosphere and to observe how it interacts with the land and ocean biospheres MOPITT’s specific focus is on the distribution
