Context: NASA plans two new missions to Venus, its first in decades

  • Venus hides a wealth of information that could help us better understand Earth and exoplanets.
  • Scientists believe Venus may once have harbored seas of water potentially suitable for life, before unknown forces triggered its extreme greenhouse effect, vaporising its oceans.
  • NASA announced plans to launch a pair of missions to Venus between 2028 and 2030 — its first in decades — to study the atmosphere and geologic features of Earth’s so-called sister planet and better understand why the two emerged so differently.
  • The two missions, dubbed DAVINCI+ (short for Deep Atmosphere Venus Investigation of Noble Gases, Chemistry and Imaging) and VERITAS (an acronym for Venus Emissivity, Radio Science, InSAR, Topography and Spectroscopy).


  • It will measure the composition of the dense, hothouse atmosphere of Venus to further understand how it evolved.
  • DAVINCI+, consisting of a fly-by spacecraft and an atmospheric descent probe, is also expected to return the first high-resolution images of unique geological characteristics on Venus called "tesserae”.


  • It will map the planet's surface from orbit to help determine its geologic history,
