Nasa is keeping an eye on world water supplies from
space tomorrow. The space agency is launching a satellite
from California for a first of its kind mission.
The project will conduct the survey of the world's oceans
, lakes and rivers, which make up about 70%
of the Earth's surface. Scientists hope the experiment will
shed new light on how climate change is impacting the
planet's water systems. If all goes to plan,
we should start getting results back in the first few
months of the new year.
