People are fascinated with space and the things in it. Thanks to the launch of an International Space Station, humans began to understand more about space. This place is helping us to understand how we can live in space. And the amazing thing to think about is that, not so long ago, this idea was pure science fiction.
Aerospace research continued its course and achieved several advances. Last year a historic feat of three missions sent to Mars was made. And this is not to say that advances have stopped, or that other planets are not targeted for study and missions.
An example of this was the NASA announcement. The agency has announced two new missions for Venus that will be launched later in the decade. These missions are aimed at learning how the planet closest to us became a hellish landscape at the same time the Earth prospered.
“These two sister missions aim to understand how Venus became an infernal world capable of melting lead on the surface. They will offer the entire scientific community the chance to investigate a planet we haven’t visited in over 30 years,” said Bill Nelson, the agency’s newly confirmed administrator.
To carry out these missions, approximately 500 million dollars were earmarked by the NASA Discovery Program. And they expect each of them to be released between 2028 and 2030.
These two missions were chosen through a competitive, peer-reviewed process based on their scientific value and the feasibility of their own plans.
The first mission is “DAVINCI +”, which stands for “Deep Atmosphere Venus Investigation of Noble gas, Chemistry, and Imaging” will gather more details about the composition of Venus’ atmosphere. The goal is to know how it was formed and evolved
In addition, the mission also aims to determine if Venus ever had an ocean. For the mission, a descending sphere will plunge into the dense atmosphere that is mixed with clouds of sulfuric acid. It will measure, with greater accuracy, levels of noble gases and other elements. With that, you will be able to know what gave rise to the runaway greenhouse effect that is seen today.
“DAVINCI +” will also send to Earth the first high-resolution images of the tesserae of Venus, which are geological features more or less comparable to those of our planet.
Analysis results may reshape scientists’ understanding of the formation of terrestrial planets.
The second mission is called “VERITAS”, which is an acronym for Venus Emissivity, Radio Science, InSAR, Topography and Spectroscopy. Her goal is to map the surface of Venus and delve into the planet’s geological history.
For this, it will use a kind of radar that is used to create three-dimensional constructions. He will map surface elevations and confirm whether volcanoes and earthquakes are still happening on Venus.
In addition, “VERITAS” will use an infrared scan to determine the rock type, which is quite unknown, and also to see if active volcanoes are releasing water vapor into the atmosphere.
The mission will be led by NASA, but the German Aerospace Center will provide the infrared mapper, and the Italian Space Agency and France’s Center National d’Etudes Spatiales will contribute to the radar and other parts of the mission.
“It’s amazing how little we know about Venus, but the combined results of these missions will tell us about the planet from the clouds in its sky, through the volcanoes on its surface to the center. It will be as if we have rediscovered the planet,” concluded Tom Wagner, NASA Discovery Program Scientist.
