DAVINCI mission: a titanium probe to study the infernal planet Venus | Video


as we know it today. It is not excluded that our home planet may sooner or later suffer the same fate, but it will not be a very positive evolution since Venus is a hellish planet whose surface is dominated by numerous active volcanoes, the atmospheric pressure is so high any probe to test, and as if that weren’t enough 284 ° superficial make it decidedly inhospitable.

In the coming years several missions will leave for Venus with the aim of studying both the atmosphere that the superficial characteristics, we know for example that in 2030 an orbiter born from the ESA-NASA collaboration called EnVision, while a year earlier the DAVINCI mission could come to life, one of the two projects selected under the Discovery program that received initial funding to kick off the developments.

DAV INCI (Deep Atmosphere Venus Investigation of Noble Gass, Chemistry and Imaging) is inspired by the famous Italian Renaissance genius and will be entirely managed by NASA’s Goddard Space Center . The mission aims to measure the atmospheric composition, both high and low of the planet, through the instruments CUVIS (Compact Ultraviolet to Visible Imaging Spectrometer) and VISOR (Venus Imaging System for Observational Reconnaissance) . The place of descent will be the Alpha Regio, a mountainous region of the plateau whose rocks may contain clues to the planet’s mysterious past.

Given the prohibitive conditions of Venus, all the instruments will be protected inside a titanium sphere . In addition to the two instruments described above, inside we will find the VLTS (Venus Tunable Laser Spectrometer) which will measure the key gases potentially linked to a past presence of water on the surface, ll VMS (Venus Mass Spectrometer) which will study the atmosphere in detail, and the VASES (Venus Atmospheric Structure Investigation) , which will measure pressure, temperature and winds during the descent.

Thanks to a transparent sapphire window present in the lower part of the sphere, the tool VENDI (Venus Descent Imager) will map the topography and composition of the area with scales of less than one meter. Finally, on the probe there will be an instrument born from a student collaboration called VfOx (Venus Oxygen Fugacity) which will allow to measure oxygen in the deep atmosphere.

Although there are still several years to go, the Goddard Space Center shared a video that gives a general overview of the mission. Nor is the choice of graphics by chance, clearly inspired by the style of our Leonardo’s writings. Waiting for new details, we leave you to his vision.
