NASA will launch 2 new missions to Venus by 2030 to return to Earth's hellish twin(VENUS)

 After ignoring our sister planet for almost three decades, NASA is heading back to Venus - and in a big way.

On Wednesday, June 2, NASA chief Bill Nelson announced that the agency would send two new envoys to Earth's inland neighbour in 2030. One of them, DAVINCI +, is a windmill that will come out and fall on the face of Venus, taking its acid clouds to end its closure. The other, VERITAS, will study the planet from orbit with radar and scanning instruments.

Earlier last year, NASA provided $ 4 million to each team to perform potential space missions that could expand into full-scale operations. It now plans to move on to two of those projects, and there is a shared Venus theme among them.

The news has delighted many in the planetary science community who have been crying for decades for NASA to return to Venus. NASA's last task to identify its planet Earth's sister was Magellan's investigation, which revolved around Venus from 1990 to 1994. Although hellfire often serves as a space shuttle that requires a sling of gravity in the most remote places, their only guests who have dedicated themselves to the last 27 years were ESA's Venus Express and Japan's Akatsuki (or "Dawn").

The first of these is called the Deep Atmosphere Venus Investigation of Honored Gas, Chemistry and Imaging, or DAVINCI + for short and non-verbal. Art will travel to Venus to photograph high-resolution images of the planet and its unique geographical features, including its continental tesserae. It will also use the "landing area" that will travel across the planet's atmosphere to collect data from gases found there. Hopefully DAVINCI + will help scientists determine if Venus ever had a sea, and understand how the planet became so large.

The second mission, VERITAS or Venus Emissivity, Radio Science, InSAR, Topography, and Spectroscopy, will travel to the planet to create a detailed, three-dimensional map of its surface using artificial radar. And it will follow the release of infrared on the surface to mark the formation of its stones, which scientists do not know much about. Through VERITAS, NASA hopes to gain a better understanding of how geological forces work in Venus and to understand why the planet developed so differently from Earth.

Both DAVINCI + and VERITAS were competing in a four-pronged pool under NASA's $ 500 million Discovery-class missions program. NASA has said it will approve two proposals, and it is expected that there will be a single Venus mission to do so. But NASA's decision to double Venus surprised us.

"Everyone hoped thttp://hat one of the two dormitories would be the goal of Venus," said Justin Filiberto, a member of the DAVINCI team and a chemist at the Lunar and Planetary Institute in Houston. "But this is amazing because it makes the Venus exploration program so small."

Two missions missed were the Io Volcano Observer, which would study Joiter's moon-flying Io volcano, and Trident, which would look at Neptune's cold Triton moon.

DAVINCI + is brief on the Deep Atmosphere Venus investigation of Distinguished Gas, Chemistry, and Imaging; the integration indicator was added when the equipment proposal was reviewed and upgraded in 2019. The full name of VERITAS is Venus Emissivity, Radio Science, InSAR, Topography and Spectroscopy.

When DAVINCI + hits the tops of the venusian cloud, it will be NASA's first task to study the spirit of Venus since 1978, and the first from any nation since the USSR Vega expedition in 1985. combine the full profile of the atmosphere of Venus, layer by layer. It will also be able to smell interesting compounds - perhaps even phosphine, which radio astronomers discovered last year, was very pleasing. Globally, phosphine is produced by microbes, which lead the group to float in the possibility of venusian clouds holding life; after a data processing error was detected, the team revised its level of phosphine levels down, which opened the door to other interesting geochemical processes.

Although DAVINCI + is not built to survive its planned hard arrival on the surface of Venus, and the arrogant conditions it will encounter there, it will recapture images of the area taken under the cloud package during its descent. Scientists hope to learn that the rocks in this region are made of continental granite or volcanic basalt. "The big difference is that if there is granite, then there is water inside Venus - and if it was ancient basalt, then there is no need for water," said Filiberto. "So that tells a very different story about staying."

VERITAS will also try to combine the appearance of the earth with Venus from orbit. "Determining whether Venus is actively involved in volcanic activity and understanding what is going on is one of the most exciting questions I would like to answer," said Jennifer Whitten, a VERITAS team member and planetary scientist at Tulane University in New Orleans, in a 2020 press release. It is likely to see changes in volcanoes and mud flows since the visit of Magellan and Venus Express, Filiberto said.

Part of what makes scientists so happy is that the forces of the universe are so intertwined. "We have a different local resolution of our data," Filiberto said. "DAVINC + will be able to identify these ancient stones with a higher resolution than VERITAS, but VERITAS will be considered worldwide, so they will be able to put our point in context."

There could be a lot of art to join a group soon. Later this month, ESA will choose between two proposals for its next medium-sized operation - one of them, EnVision, and the other Venus orbiter. Also, Russia and India plan separately on their trip to Venus.
