What Davinci will look for on Venus

(ORDO NEWS) — The Davinci mission, bound for Venus in 2029, will take the first measurements of the amount of oxygen present near the surface of the second planet from the Sun.

However, before going to Venus, scientists will urgently need to figure out the organic and chemical composition of the planet.

To explore the deep atmosphere of Venus, the Davinci mission will travel to Venus in 2029. The spacecraft will be equipped with a special instrument (Venus Oxygen Fugitity, VfOx) to determine the amount of oxygen present near the planet’s surface.

NASA said that by analyzing the VfOx measurements, scientists will for the first time try to determine which minerals are most stable on the surface of Venus in the highlands and link rock formation to recent rock changes.

What is VFX?

The oxygen quantity measurement sensor (VfOx) is being developed by undergraduate and graduate students for the DAVINCI mission to the atmosphere of Venus.

The sensor will be mounted on the outside of the reentry sphere, where it will measure oxygen fugacity, the partial pressure of oxygen in the deep atmosphere below Venus’s clouds.

The descent probe will enter Venus after two years of arriving in Venus’s orbit, absorbing and analyzing atmospheric gases and collecting images as it descends to the planet’s surface in the Alpha region.

The VFOX will work in a similar way to the oxygen sensor used in many automotive engines, which measures the amount of oxygen in the fuel system.

“Understanding how much oxygen is contained in the atmosphere of Venus will be important in preparation for the characterization of Venus-like worlds outside our solar system and for future observatories.

Knowing the amount of oxygen on Venus will help scientists study these distant worlds,” NASA said in a statement.

What is the main purpose of the DAVINCI mission?

The Davinci mission will measure the composition of Venus’s atmosphere to understand how it formed and evolved, and to determine if the planet ever had an ocean. The mission will look for the first clues to the possibility of life on Venus.

Venus and Earth are similar in size and density, so these planets are hypothetically very similar. And yet they are strikingly different. The spacecraft will study signs of planetary changes that could occur on Earth due to climate change.

Davinci will also send the first high-quality images of Venus detailing its geological features that could be comparable to Earth’s continents. Scientists suggest that there is plate tectonics on Venus.
