Each is expected to launch in the 2028-2030 timeframe. The selected missions are DAVINCI (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging) and VERITAS (Venus Emissivity, Radio Science, InSAR, Topography, and Spectroscopy). On June 2, 2021, NASA announced it had selected two new missions to Venus as part of the agency's Discovery Program. The research marked the latest clue to untangling how and why Venus and Earth are so different.
A study of data from the Parker mission confirmed that Venus’ upper atmosphere undergoes puzzling changes over a solar cycle, the Sun’s 11-year activity cycle. This was the first direct measurement of the Venusian atmosphere in nearly 30 years – and it looked quite different from Venus’s past. During that brief encounter, Parker detected a natural radio signal that revealed the spacecraft had flown through the planet’s upper atmosphere. NASA’s Parker Solar Probe has made multiple flybys of Venus, coming within about 515 miles (830 kilometers) of the surface on July 11, 2020. Japan’s Akatsuki Venus Climate Orbiter has been orbiting Venus since 2016. More recently, ESA’s Venus Express orbited from 2006 to 2014. It found volcanoes, long lava channels, pancake-shaped domes, and evidence of hot mantle plumes at depth (like the one responsible for creating the Hawaiian islands). 10, 1990, and over the next four years, it used radar to pierce the planet's clouds, providing the first clear views of most of the planet’s surface.
and other space agencies have explored Venus, including NASA’s Magellan. Since Mariner 2, numerous spacecraft from the U.S. During a 42-minute scan, the spacecraft gathered significant data on the atmosphere and surface before continuing to heliocentric orbit. Venus became the first planet to be explored by a spacecraft when NASA’s Mariner 2 successfully flew by the planet at a range of 21,660 miles (34,854 kilometers) on Dec.
