NASA to Explore Divergent Fate of Earth’s Mysterious Twin with Goddard’s DAVINCI+

Although Earth and Venus are similar in size and position, they are very different Earths today. The earth has ocean water and plenty of life, Venus is dry and deadly hospitable. Although it is somewhat closer to the Sun – about 70 percent of Earth’s distance – Venus is much hotter, with temperatures at the surface high enough to melt lead.

The scorched landscape is obscured by clouds of sulfuric acid, and it is smothered by a thick atmosphere of mostly carbon dioxide at over 90 times the pressure of Earth’s, which causes the air to behave more like a fluid than a gas near its surface.

But scientists believe that in an earlier time, Venus may have been more like Earth, there was an ocean of water that was probably habitable for life, probably for billions of years. They speculate that anything that causes Venus to have a “runaway greenhouse” effect in the atmosphere, causes the temperature to crank up and its oceans to evaporate.

NASA’s DAVINCI+ mission is ready to explore whether Venus is habitable and to understand how this kind of world ended up with such enthusiasm.James Garvin, chief investigator of DAVINCI+ on NASA’s Goddard space flight, said, “The record book of climate change, habitat evolution and what happens when a planet loses its long lifespan in the ocean, Venus is the ‘Rosta Stone’, said Greenbelt, the center of Maryland.”

‘Tough’, because every source is hidden behind a huge opaque environment in a hospitable situation to explore the surface, so we have to be clever and bring our best ‘science tools’ like Venus as a mission in an innovative way. DAVINCI +. After Vinci’s inspirational and visionary Renaissance thinking, we named our mission DAVINCI+ which went beyond science to connect with engineering, technology and even industry. “

The scientific impact of DAVINCI + will reach orbit around other stars (exoplanets) even outside the solar system, reaching important targets for NASA’s upcoming James Webb Space Telescope. However, these planets can be difficult to explain, especially if they are surrounded by dense Venus-like clouds.

“Venus is our ‘backyard exoplanet’ that can help us understand these remote analog worlds by providing ground truths to improve the computer models we use to interpret the exo Venus planets,” said Giarda Arden “But there is a lot about Venus that we still don’t understand and that’s where DVNCI + comes in. Interestingly, if Venus was habitable in the past, some exo-Venus planets might be habitable too! That’s how the habitable earth expands elsewhere in the universe and how habitable planets evolve over time in common texts. “

The Nobel Gases, Chemistry and Imaging Plus will have a spacecraft and probe into the Deep Atmosphere Venus Investigation Mission. The spacecraft measures the velocity of the clouds and the composition of the surface of the map measuring the heat emission from the surface of Venus that escapes into space through the vast atmosphere.

This investigation will take the first high-resolution images of Alpha Regio, an ancient highland with a twice-sized roadside hill in Texas, looking for evidence that crystal water surface materials were affected in the past.

The launch is targeted for the FY2030 with two flybikes on Venus before the probe emerges. Flybies are the initial stage of the study of atmospheric conduction and the remote sensing mission of surface composition maps. About two years later, the probe will be unveiled to conduct an atmospheric investigation as it descends about an hour before landing at Alpha Reggio.

“The next step in exploring Venus requires a suitable instrument payload that can use modern skills to create specific datasets that transform our understanding of our planet’s environment,” said Stephanie Getty, deputy chief investigator at NASA’s DAVINCI+.

“DAVINCI+ has today taken proven materials to the most innovative science problems of Venus and we are eager to bring along an enthusiastic science community on our journey to provide datasets of chemical, geological and atmospheric dynamics that will generate the next great discoveries and the next great question – Venus and About Earth like Venus.

The probe will have four instruments. Two of these – the Venus Mass Spectrometer (VMS) and the Venus Tunable Laser Spectrometer (VTLS) – will take the first fully structural study of the entire cross-section of Venus’s atmospheric gases, how, when, and how to look for it. Why Venus’s climate can change so dramatically.

The third instrument, the Venus Atmospheric Structure Probe (VASI), will measure pressure, temperature and wind from about 43.5 miles (70 kilometers) at a resolution 10 times higher (or more) than any Venus probe before the Earth’s surface.

After the probe descends below the dense cloud layer, the Venus Origin Image (VENDI) instrument will take hundreds of near-infrared images of the Alpha Regio highlands, which the team will use to map topography and compositions. These images make Venus unique in higher resolutions of landers (usually near the surface).

The spacecraft will have a component, a four-camera suite called VISOR (Venus Imaging System Orbit for Reconnaissance for Venus Imaging System). A camera will be sensitive to ultraviolet light to track the motion of clouds in the atmosphere. Additionally, the three-camera suite, which is sensitive to near-infrared light, will be able to detect surface compositions on regional scales by analyzing infrared heat emissions from the surface when the spacecraft is on the side of the Venus night.

Since the rock composition may have been influenced by water, these images will give clues as to how the shape of Venus in the ancient oceans was shaped. The camera suite will provide a map of Ishtar Tera’s first composition, with the high latitude “continent” in Venus being limited to a length of 6..6 miles (11 kilometers). When the oceans became extinct about a billion years ago, Ishtar’s Venus could be the last manifestation of a kind of plate tectonics.

NASA Goddard will conduct project systems engineering to develop the probe flight system as well as conduct project projects for the main investigative agency and mission. Goddard will create VMS instruments in collaboration with the University of Michigan and Vassi Instrument’s sensor system. Goddard leads the project science support team.

Major partners are Lockheed Martin, Denver, Colorado, who will build the aeroshell and backshell (the entry and descent system) to carry the probe into the atmosphere and provide the parachutes to position it into the proper descent trajectory, as well as the probe carrier spacecraft, the flyby telecom system for the probe, the flyby science platform for the VISOR camera suite, and the carrier/orbital spacecraft. 

The Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland will provide the two-way Frontier radio that the mission will use for communication between the probe and spacecraft, as well as science leadership of the VASI element. NASA’s Jet Propulsion Laboratory, Pasadena, California, will provide the VTLS instrument. 

Malin Space Science Systems, San Diego, California, will provide the cameras including the VenDI descent camera and the orbital/flyby VISOR suite. NASA’s Langley Research Center, Hampton, Virginia, will provide entry-descent-systems support and NASA’s Ames Research Center at Moffett Federal Airfield in California’s Silicon Valley will collaborate on the thermal protection system and entry-systems measurement systems. KinetX, Inc., Tempe, Arizona, will support flight dynamics and trajectory development with Goddard and Lockheed Martin.

Discovery-Program-class missions like DAVINCI+ complement NASA’s larger “flagship” planetary science explorations, with the goal of achieving outstanding results by launching more smaller missions using fewer resources and shorter development times. They are managed for NASA’s Planetary Science Division by the Planetary Missions Program Office at Marshall Space Flight Center in Huntsville, Alabama. The missions are designed and led by a principal investigator, who assembles a team of scientists and engineers to address key science questions about the solar system.
