NASA\u2019s DAVINCI \u2014 Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging \u2014 mission embodies the spirit of innovation and exploration that its namesake, Leonardo da Vinci, was famous for.<\/p>\n

Scheduled to launch in the early 2030s, DAVINCI<\/a> will explore Venus with both a spacecraft and a descent probe. DAVINCI\u2019s probe will be the first in the 21st century to brave Venus\u2019 atmosphere as it descends from above the planet\u2019s clouds down to its surface. Two other missions, NASA\u2019s VERITAS<\/a> and ESA\u2019s (<\/a>European<\/a> Space Agency) Envision<\/a>, will also explore Venus in the 2030s from the planet\u2019s orbit.<\/p>\n

The DAVINCI spacecraft will study Venus\u2019 clouds and highlands during two flybys. It also will release a spherical probe, about 3 feet wide, that will plunge through the planet\u2019s thick atmosphere and corrosive clouds, taking measurements and capturing high-resolution images of the Venusian surface as it descends below the clouds.<\/p>\n

Here are some of DAVINCI\u2019s coming \u201cfirsts\u201d in Venus exploration:<\/p>\n

Exploring Solar System\u2019s One-of-a-Kind Terrain \u00a0<\/strong><\/h3>\n

The DAVINCI mission will be the first to closely explore Alpha Regio, a region known as a \u201ctessera.\u201d So far found only on Venus, where they make up about 8% of the surface, tesserae are highland regions similar in appearance to rugged mountains on Earth. Previous missions discovered these features using radar instruments, but of the many international spacecraft that dove through Venus\u2019 atmosphere between 1966 and 1985, none studied or photographed tesserae.<\/p>\n

Thought to be ancient continents, tesserae like Alpha Regio may be among the oldest surfaces on the planet, offering scientists access to rocks that are billions of years old.<\/p>\n

By studying these rocks from above Alpha Regio, DAVINCI scientists may learn whether ancient Venus had continents and oceans, and how water may have influenced the surface.<\/p>\n

Photographing One of the Oldest Surfaces<\/strong> <\/strong>on Venus<\/strong><\/h3>\n

The DAVINCI probe will capture the first close-up views of Alpha Regio with its infrared and optical cameras; these will also be the first photos of the planet\u2019s surface taken in more than 40 years.<\/p>\n

With surface temperatures reaching 900\u00b0 F and air pressure 90 times that of Earth\u2019s, Venus\u2019 harsh environment makes exploration challenging, while its opaque atmosphere obscures direct views. Typically, scientists rely on radar instruments from Earth or Venus-orbiting spacecraft to study its terrain.<\/p>\n

But DAVINCI\u2019s probe will descend through the atmosphere and below the clouds for a clear view of the mountains and plains. It will capture images comparable to an airplane\u2019s landing view of Earth\u2019s surface. Scientists will use the photos to compile 3D maps of Alpha Regio that will provide more detail than ever of Venus\u2019 terrain, helping them look for rocks that are usually only made in association with water.<\/p>\n

Unveiling Secrets of Venus\u2019 Mysterious Lower Atmosphere<\/strong><\/h3>\n

The DAVINCI mission will be the first to analyze the chemical composition of Venus\u2019 lower atmosphere through measurements taken at regular intervals, starting from approximately 90,000 feet above the surface and continuing until just before impact.<\/p>\n

This region is critical because it contains gases and chemical compounds that may originate from Venus\u2019 lower clouds, surface, or even subsurface.<\/p>\n

For example, sulfur compounds detected here could indicate whether Venusian volcanoes are currently active or were active in the recent past. Noble gases (like helium or xenon), on the other hand, remain chemically inert and maintain stable concentrations, offering invaluable clues about Venus\u2019 ancient history, such as the planet\u2019s past water inventory.<\/p>\n

By comparing Venus\u2019 noble gas composition with that of Earth and Mars, scientists can better understand why these planets \u2014 despite forming from similar starting materials \u2014 evolved into dramatically different worlds.<\/p>\n

Moreover, DAVINCI\u2019s measurements of isotopes and trace gases in the lower atmosphere will shed light on Venus\u2019 water history, from ancient times to the present, and the processes that triggered the planet\u2019s extreme greenhouse effect.<\/p>\n

State-of-the-Art Technology to Study Venus in Detail<\/strong><\/h3>\n

Thanks to modern technology, the DAVINCI probe will be able to do things 1980s-era spacecraft couldn\u2019t.<\/p>\n

The descent probe will be better equipped than previous probes to protect the sensitive electronics inside of it, as it will be lined on the inside with high-temperature, multi-layer insulation \u2014 layers of advanced ceramic and silica fabrics separated by aluminum sheets.<\/p>\n

Venus\u2019 super thick atmosphere will slow the probe\u2019s descent, but a parachute will also be released to slow it down further. Most Earth-friendly parachute fabrics, like nylon, would dissolve in Venus\u2019 sulfuric acid clouds, so DAVINCI will have to use a different type of material than previous Venus missions did: one that\u2019s resistant to acids and five times stronger than steel.<\/p>\n

NASA\u2019s Goddard Space Flight Center in Greenbelt, Maryland, is the principal investigator institution for\u00a0DAVINCI\u00a0and will perform project management for the mission, provide science instruments,\u00a0as well as project systems engineering to develop the\u00a0in-situ\u00a0probe flight system\u00a0that will enter the atmosphere of Venus. Goddard also leads the\u00a0overall science for the mission\u00a0with an external science team from across the United States. Lockheed Martin Space in Denver, Colorado, will build the\u00a0carrier\/relay\u00a0spacecraft.\u00a0DAVINCI\u00a0is a mission within the Discovery Program, managed by NASA\u2019s Marshall Space Flight Center in Huntsville, Alabama, for the agency\u2019s Science Mission Directorate in Washington.<\/em><\/p>\n
