Venus has been compared to 'Earth's evil twin' for its extreme surface temperatureDAVINCI+ (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging) will measure Venus' atmosphere to understand how it formed and evolved and determine whether it ever had an ocean. Subsequent NASA missions have flown by Venus, including the Parker Solar Probe, which detected a radio signal from the planet's atmosphere last month, CNN reported. The other mission, VERITAS (Venus Emissivity, Radio Science, InSAR, Topography, and Spectroscopy) will map the surface of Venus and look at its geologic history in an effort to find out why it developed so much differently than Earth. It will use a synthetic aperture radar and 'chart surface elevations over nearly the entire planet to create 3D reconstructions of topography' to see whether plate tectonics and volcanic activity are still happening on the planet, NASA added. Approximately 700 million years ago, it underwent a 'dramatic transformation' --possibly due to volcanic eruptions -- that completely altered the planet.
