Radar array tests the atmosphere at pole position

David Cyranoski

A three-metre radar antenna was among the equipment carried by Kaoru Sato as she set off for the South Pole late last month. Sato, who is based at the National Institute of Polar Research (NIPR) in Tokyo, will do a pilot assessment for a project that could make the Antarctic home to 1,000 such antennas set up in a circular array some 160 metres across.
