Web7 jun. 2024 · The intense surface conditions also mean rovers are impractical. One suggestion has been a balloon mission. We have a low resolution image of the surface of Venus, thanks to NASA's Magellan mission in 1990, which mapped the surface using radar. The Davinci probe will take surface images using infrared light during its descent. WebAbout the mission. The Magellan spacecraft, which arrived at Venus in 1990, made the first global map of the surface of Venus as well as global maps of the planet's gravity field. The mission produced surprising findings about Venus, including a relatively young planetary surface possibly formed by lava flows from planet-wide volcanic eruptions.
