Terra (EOS AM-1) Flight Mission
The Terra satellite is the flagship of the Earth Observing System (EOS). The satellite was originally designated EOS AM-1. Terra provides global data on the state of the atmosphere, land, and oceans, as well as their interactions with solar radiation and with one another. EOS is the centerpiece of NASA's Earth Science Enterprise (ESE).
Terra was launched December 16, 1999.
The instruments on Terra observe and measure the state of the
Earth's systems, while also monitoring global environmental changes over
time. Terra carries five state-of-the-art instruments uniquely designed to provide data
with unprecedented precision, quality, and scope.
Data from these instruments will be processed
into continuous long-term measures of the state of the atmosphere, land,
and oceans. The 5 instruments are
On February 24, 2000,
Terra began collecting what will ultimately become a new 15-year global
dataset on which to base scientific investigations about our complex home planet.
The
instruments on Terra
(ASTER, CERES, MISR, MODIS, and MOPITT)
complement each other with different views of the Earth's surface and
atmosphere. The instruments are intended to obtain information about
