Over the past two decades my company has used
imaging radar satellites to map oil on the sea surface for 70 million square kilometres of ocean.

Several nations, including the United States, have already launched
radar -
imaging satellites, but efforts abound to push the envelope further.
For instance, ESA has an agreement to use
imaging radar from two Canadian
satellites, but that will produce far less data than Envisat.
Some
satellites, including National Reconnaissance Office
imaging satellites, already have warning systems, while air force
radar can track boosters or other objects in space.
The team then extrapolated these data over the varying landscape to produce a seamless map, using NASA imagery from the Moderate Resolution
Imaging Spectroradiometer (MODIS) instrument on NASA's Terra spacecraft, the QuikScat scatterometer
satellite and the Shuttle
Radar Topography Mission.
Using airborne
radar and
satellite imaging, researchers have located more than 400 of these so - called subglacial lakes beneath the Antarctic ice sheet over the past 50 years.
The two
satellites are in a polar orbit with an inclination of about 82 degrees and operates 3 distinct instruments: a
radar altimeter; an
imaging spectrometer; and an infrared radiometer.
The
radar imaging system used by Envisat and other
satellites is particularly suited to observe polar areas, as it can acquire images through cloud or fog, and night and day.
His research focuses on understanding the interactions of ice, ocean and climate, in particular using
imaging radar observations from
satellites and airplanes to determine how the ice sheets in Antarctica, Greenland and Patagonia will respond to climate change and affect global sea level.
The launch was primarily designed to bring the PAZ
satellite to orbit (which was deployed as planned into a low Earth, sun - synchronous polar orbit), a
satellite for a Spanish customer that's designed to provide geocommunications and
radar imaging for both government and private commercial customers.
