At the end of its planned 243-day mission, by which time Venus will have completed a full rotation beneath Magellan's orbit, over 70 percent of the Venus surface shall have been mapped to high resolution; the volume of data thus obtained will exceed that from all previous U.S. planetary missions combined. An innovative SAR instrument will map Venus to an order-of-magnitude higher resolution than that possible with previous probes. Parameters controlling the spacing of SAR S-band pulses' transmission and reception, their number and frequency of repetition, etc., are changed as many as 300 times per mapping pass in order to accommodate the spacecraft's constantly varying orbital geometry.
