Destination
Elliptical Venus orbit at approximately 297 × 8,463 km altitude and 85.5° inclination for radar mapping of Venus, followed by aerobraking and a controlled atmospheric entry after completing 98% surface coverage
End Date
1994-10-13
Launch Site
Outcome
Magellan mapped 98 percent of Venus at high resolution, revealed widespread volcanic and tectonic landforms, and completed an aerobraking and gravity campaign before entering the atmosphere on October 13, 1994.
