all around the globe satellites are
recording change but there is a
problem just as we are able to capture
and measure these changes many of the
current Fleet of satellites are coming
to the end of their
lives satellites need fuel to stay in
their orbits
when their time is up they must either
use the last of their fuel to boost
themselves far away from the earth or
descend and burn up on
re-entry it's predicted that the number
of NASA's Earth observing Satellite
Systems will go from 20 down to fewer
than 10 within the next decade

the constant stream of information from
these vital instruments in space will
fade if we failed to replace these
satellites we could lose our ability to
track the web of connections that is
fundamental to
life the complex
interactions would be absolutely
invisible to us without a larger view of
the Earth
it's the consistency and the amount of
data that they provide that allows us to
understand the processes that are going
on in the earth that are important to
maintaining Life as We Know It
