   Jun 2, 2021 · VERITAS will map Venus’ surface to determine the planet’s geologic history and understand why it developed so differently than Earth. Orbiting Venus with a synthetic aperture radar, VERITAS will chart surface elevations over nearly the entire planet to create 3D reconstructions of topography and confirm whether processes such as plate tectonics and volcanism are still active on Venus.

   How we study Venus. Venus was the first planet to be visited by a spacecraft. In 1962, NASA’s Mariner 2 flew by the planet and discovered it was a hot world with no self-generated magnetic field. The Soviet Union became the world leader in early Venus exploration after that, sending multiple atmospheric probes and as many as ten landers to ...

   Outer Solar System. The outer solar system consists of four “gas giants”: Jupiter, Saturn, Uranus, and Neptune. These four planets do not have a defined surface. Jupiter and Saturn consist mostly of hydrogen and helium. Uranus and Neptune consist mostly of water, methane, and ammonia, and they are sometimes referred to as the “water ...

   How we study Neptune. It takes a spacecraft a long time to reach Neptune, and we’ve only done it once. NASA launched the nuclear-powered Voyager 2 spacecraft in 1977 to fly past every giant planet in the outer solar system, taking advantage of a rare planetary alignment that only happens every 175 years. Voyager 2 passed Neptune in August 1989.

   A critical question for scientists who search for life among the stars: How do habitable planets get their start? The close similarities of early Venus and Earth, and their very different fates, provide a kind of test case for scientists who study planet formation. Similar size, similar interior structure, both harboring oceans in their younger ...

   Why do scientists study Venus?

   • By studying Venus, scientists learn how Earth-like planets evolve and what conditions exist on Earth-sized exoplanets. Venus also helps scientists model Earth’s climate, and serves as a cautionary tale on how dramatically a planet’s climate can change. Venus' surface Only 4 spacecraft have ever returned images from Venus’ surface.

   Why do we study Neptune?

   • The majority of worlds we’ve found around other stars are Neptune-sized. By studying Neptune we learn about other solar systems and whether or not ours is unique. Neptune, along with its cousin Uranus, is the least-explored planet in our solar system, having been visited by a spacecraft only once.

   Could Venus help us understand Earth and exoplanets?

   • Venus hides a wealth of information that could help us better understand Earth and exoplanets. NASA’s JPL is designing mission concepts to survive the planet’s extreme temperatures and atmospheric pressure.

   Does Venus have a rocky planet?

   • Data from VERITAS about the surface and interior of Venus will help scientists make useful comparisons between the four rocky planets of our solar system (Mercury, Venus, Earth, and Mars), as well as rocky exoplanets. The outer solar system consists of four “gas giants”: Jupiter, Saturn, Uranus, and Neptune.

   Will NASA send a probe to study Venus?

   • NASA usually undertakes only one flagship mission — a big, ambitious, expensive effort — at a time. A Venus flagship mission under consideration would include two balloons that would float in the atmosphere for a month. And at least one private company, Rocket Lab, wants to send a small probe to study Venus in the coming years.

   Could Venus' atmosphere reshape our understanding of terrestrial planet formation?

   • This would be the first U.S.-led mission to Venus’ atmosphere since 1978, and the results from DAVINCI+ could reshape our understanding of terrestrial planet formation in our solar system and beyond. James Garvin of Goddard Space Flight Center in Greenbelt, Maryland, is the principal investigator. Goddard provides project management.
