Ulysses will reach its maximum latitude this week, as the European Space Agency spacecraft continues its pass over the Sun's south polar region. The craft will climb to 80.2°south of the Sun's equator September 13.

Analyses of some surprising data from its trek across the mid-latitudes have already expanded the frontier of knowledge about the nature of the Sun's corona and solar wind near the poles and have increased excitement in the science community about this first-ever polar exploration.
