Exploring the mysteries of Venus

10-24-2021

Today’s Video of the Day from NASA Goddard explores the mysteries of Venus, such as whether it was once a habitable planet like Earth. 

Scientists want to know if Venus ever hosted life. To do this, they must study the history, geology, and atmosphere of the planet. This is precisely the goal of NASA’s DAVINCI (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging) mission. 

While Venus and Earth are similar in size and density, they are also extremely different. For example, air pressure at the surface of Venus is 90 times that of Earth. Scientists want to understand why the planets evolved in such different ways. 

These and other questions will be Investigated by the DAVINCI mission, which is scheduled to launch in 2029

Walter Kiefer is a planetary geophysicist at the Lunar and Planetary Institute (LPI) and a member of DAVINCI science team.

“DAVINCI will make detailed measurements of the chemistry of the atmosphere of Venus, revealing key features of its evolution for the first time,” said Kiefer.

“These observations will tell us about the origin of the atmosphere, whether or not Venus had an ocean early in its history, and how the rate of volcanic activity has varied with time.”
