    The Magellan Venus orbiter

    Area of Science:

    • Planetary Science
    • Radar Astronomy
    • Venus Exploration

    Background:

    • The Magellan mission utilized a sophisticated radar system aboard the Venus orbiter.
    • This instrument was key to mapping the Venusian surface and understanding its topography and thermal properties.

    Purpose of the Study:

    • To detail the capabilities and performance of the Magellan Venus orbiter's radar system.
    • To present the initial findings on Venus's surface topography and emissivity.

    Main Methods:

    • Employing a 12.6-centimeter wavelength radar system with three distinct data-taking modes: synthetic-aperture, altimetric, and thermal emission radiometry.
    • Achieving surface imaging resolutions between 120 and 300 meters with synthetic-aperture radar.
    • Measuring relative height with accuracies approaching 5 meters in altimetric mode, with absolute uncertainties around 50 meters.

    Main Results:

    • The synthetic-aperture radar provided detailed surface imagery.
    • Altimetric data revealed topographic variations, with the highest point identified on Maxwell Mons at a planetary radius of 6062 kilometers.
    • Surface emissivities were determined with an absolute accuracy of approximately 0.02.

    Conclusions:

    • The Magellan radar system effectively mapped Venus's surface, providing high-resolution topographic and thermal data.
    • The mission successfully identified key geological features, including the highest elevations on the planet.
    • Archival data products are available for future research.
