    Radar measurements reveal significant Venus surface height variations near the equator. A notable 3-kilometer mountain range was identified, featuring unusually steep slopes for Venusian topography.

    Area of Science:

    • Planetary Science
    • Geophysics

    Background:

    • Understanding Venus's topography is crucial for planetary evolution studies.
    • Previous data provided limited resolution of equatorial surface features.

    Purpose of the Study:

    • To map equatorial surface height variations on Venus.
    • To identify and characterize significant topographical features.

    Main Methods:

    • Utilized extended series of interplanetary radar echo delay measurements.
    • Analyzed radar data to determine surface height with resolutions between 200-400 km.

    Main Results:

    • Estimated surface height variations across the entire equatorial region.
    • Identified a mountainous section with a 3-kilometer peak height at 100 degrees longitude.

  • Observed an unusually steep eastern slope averaging 0.5 degrees.

    • Conclusions:

    • Venus's equatorial region exhibits significant topographical diversity.
    • The identified mountain and steep slope present unique geological features for further study.
