The earliest satellite maps of Arctic and Antarctic sea-ice have been assembled by scientists. They were made using data from NASA's Nimbus-1 spacecraft, which was launched in 1964 to test new technologies for imaging weather systems from orbit. The satellite's old pictures have now been re-analysed to determine the extent of the marine ice at the poles in the September of that year. Regular mapping from space did not begin until 1978.
