NASA will launch a mission to fly from Venus. The spacecraft is expected to land in the planet’s hostile environment in 2029. DAVINCI is an acronym for “Deep Atmosphere Venus Investigation of Noble Gases Chemistry and Imaging”, which can be translated as “Investigation of Venus’s Atmosphere”. Be the first to study Venus by flyby and race.
The spacecraft is expected to explore Layered Venus’s atmosphere and reach its surface in June 2031. The DAVINCI mission will be able to capture data about Venus that scientists have been eager to measure since the early 1980s.
Only two of NASA’s missions have visited its second closest planet to the Sun – Pioneer in 1978 and Magellan in the early 1990’s.
The spacecraft will basically serve as a flying chemistry laboratory, capable of measuring various aspects of Venus’s atmosphere and climate and taking images of the first lineage of the planet’s highlands.
The mission’s equipment will be able to map the surface of Venus and find out the composition of Venus’s mountains.
According to NASA scientists, these features called “Tessera” may be similar to the Earth’s continents, meaning that Venus may have plate tectonics.
“This set of chemical, environmental and hereditary imaging data will paint a picture of Venus’s stratified atmosphere and how it interacts with the mountain surface of Alpha Regio, Texas’ double size,” said Jim Garvin, director of DAVINCI. And investigators at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, in a statement.
“These measurements will allow us to evaluate the historical aspects of the atmosphere, as well as to detect special types of surface rocks such as granites, as well as explore landscape features that will tell us about incense or other formation processes.”
This activity will examine the possibility of Venus being an ocean in the deepest part of the atmosphere by measuring the components of air and water. Venus must have been the first habitable world in our solar system, with a climate similar to that of the oceans and the earth – but something happened to transform it into a planet with a temperature that is hot enough to melt lead.
According to a 2019 study, Venus is likely to retain a constant temperature and liquid water for billions of years before an event can cause drastic changes on the planet. Michael Way, a study author at the Goddard Institute for Space Science at NASA in New York, is also a co-author. A 2016 study on past Venus weather and oceans.
Now, Venus is an almost dead planet with a toxic atmosphere 90 times thicker than our home planet and the surface temperature reaches 462 degrees Celsius.
Since DAVINCI needs to fly several times over Venus, it will use two instruments to study the clouds and to map the highlands from orbit. The vehicle will then launch a decent probe carrying five devices to the surface.
The descent will take about an hour and a heat shield will be used to protect the probe until it reaches an altitude of about 67 km above the surface. It will then drop the shield to sample and analyze atmospheric gases. Hundreds of images will also be captured after the Descent Probe clears the cloud of Venus 30,500 meters from the surface.
“The spacecraft will land on Mount Alpha Regio, but once it lands, it does not need to be operated, as all necessary scientific data will be collected before it reaches the surface,” Goddard Deputy Chief Investigator Stephanie Getty said in a statement. “If we survived the landing at a speed of about 25 miles per hour (11 m / s), we could operate on the surface for 17 to 18 minutes under ideal conditions.”
