Venus, apart from the Moon, is the brightest object in the night sky, fascinating people for thousands of years. It’s a harsh environment, with sulfuric acid on its surface, and it appears to be a volcanic world with an extreme atmosphere. However, Venus, often called Earth’s sister planet, might not have always been so unwelcoming. Scientists think Venus may have once resembled Earth.
After years of being overlooked, planetary scientists are once again focusing on Venus to uncover secrets about our planet’s past and future. Venus is sometimes referred to as the “once and future Earth.” NASA is embarking on a new mission into deep space with an initial budget of $500 million for two programs: DAVINCI and VERITAS. These missions aim to send probes to Venus within the next decade. The goal is to enhance our understanding of Earth’s evolution and why it is habitable while other planets are not. By studying Venus, scientists hope to learn more about Earth and the development of life.
Venus and Earth are rocky planets of similar size, formed about 4.5 billion years ago. This raises the question: how did two planets with so much in common become so different? This presents an exciting opportunity for scientists, as Venus is the most Earth-like planet that we know the least about. Venus has a massive atmosphere, about a hundred times thicker than Earth’s, which holds many mysteries yet to be uncovered.
Inspired by Leonardo da Vinci, the DAVINCI mission is set to launch in 2029. It includes a spacecraft that will fly by Venus twice before releasing a descent probe. This probe, protected by a heat shield, will enter Venus’s atmosphere to gather data about its elemental properties, capture images of the landscape, and eventually land on the surface. The probe is specially designed to withstand extreme environmental changes, transitioning from cold and low pressure to hot and high pressure in a short time. This is a significant challenge due to Venus’s dense atmosphere and harsh surface conditions.
Exploring Venus has historically been challenging. Missions like Mariner 2 and the Soviet Union’s Venera missions provided limited insights into the planet’s desolation. The Magellan spacecraft, launched in 1989, was the first to map Venus’s entire surface, revealing volcanic activity. However, Mars soon became the focus of planetary exploration due to its engineering challenges. The success of Mars missions has provided valuable insights and techniques that can now be applied to Venus. The upcoming DAVINCI and VERITAS missions will use advanced technology to explore Venus in detail.
The DAVINCI mission will use five primary science instruments to analyze the chemical composition of the atmosphere, measure winds, pressure, and temperature, and investigate the presence of oxygen. These instruments will fit together like a jigsaw puzzle within the probe. In many ways, the investigations of Mars and Venus seek similar answers about the presence of water, both in the past and present. Scientists want to know if Venus, often seen as Earth’s “evil twin,” was once more like its identical twin, possibly with vast surface oceans.
Studying Venus’s history can help in the search for life beyond our solar system. By examining Venus, scientists may find that the boundaries of habitability are not as clear-cut as once thought. High-resolution images will help identify the makeup of Venus’s surface materials, including granite, which forms from water-rock interactions.
The VERITAS mission, launching in 2028, will study Venus from orbit, enhancing the science obtained from both missions by comparing visual images with radar data. This comprehensive approach aims to understand the geological processes that shape rocky planets and how they interact with the atmosphere. Both missions seek to answer fundamental questions about the history of water on Venus and why it diverged from Earth’s path. Understanding these processes may provide insights into Earth’s future and the potential for habitability on other planets.
The exploration of Venus represents a significant opportunity for scientific discovery, and the teams behind these missions are eager to bring Venus into focus for humanity.
Using materials like plastic bottles, balloons, and colored liquids, create a model that represents the layers and composition of Venus’s atmosphere. This hands-on activity will help you understand the extreme conditions on Venus and how they differ from Earth’s atmosphere.
Conduct research on the similarities and differences between Venus and Earth. Prepare a presentation that highlights key aspects such as size, atmospheric composition, and surface conditions. This will deepen your understanding of why Venus is often referred to as Earth’s “sister planet” and how their paths diverged.
Work in groups to design your own mission to Venus. Consider the challenges faced by the DAVINCI and VERITAS missions and propose solutions. Present your mission plan, including objectives, instruments, and expected outcomes. This activity will engage your creativity and problem-solving skills.
Using a computer simulation or virtual reality tool, explore the surface of Venus. Observe the volcanic landscape and thick atmosphere. Reflect on how these conditions compare to Earth’s and what they reveal about planetary evolution.
Participate in a debate on the significance of exploring Venus compared to other planets like Mars. Discuss the potential scientific discoveries and their implications for understanding Earth’s past and future. This will help you articulate the value of planetary exploration and its impact on science.

Venus, other than the Moon, is the brightest object in the night sky, captivating people for millennia. It’s a very harsh place, with sulfuric acid at the surface, and it seems to be an inherently volcanic world with an atmosphere that is quite extreme. However, Earth’s sister planet may not have always been so inhospitable. Scientists believe that Venus may have once looked more like Earth in the past.
After decades of neglect, planetary scientists are turning their attention back to the solar system’s second planet to unlock secrets of our world’s past and perhaps what lies ahead. Venus is often referred to as the “once and future Earth.”
NASA is embarking on a new journey into deep space with an initial budget of $500 million for two new programs: DAVINCI and VERITAS. These missions will launch planetary probes designed to visit Venus within a decade. The hope is that these missions will enhance our understanding of how Earth evolved and why it is currently habitable when others in our solar system are not. By gathering new data about Venus, scientists also expect to learn more about Earth and the evolution of life.
Both Venus and Earth are rocky bodies of roughly the same size, formed about four and a half billion years ago. The question arises: how did two worlds with so much in common become so different? This presents an incredible opportunity for scientists, as Venus is the most Earth-like world that we know the least about.
Venus has a massive atmosphere, which is about a hundred times that of Earth’s, and it tells a story that we have yet to fully understand. Inspired by the Italian artist Leonardo da Vinci, the team created an acronym for their mission to honor this Renaissance figure, known for his contributions to science, engineering, and art.
The DAVINCI mission is currently scheduled to launch in 2029 and includes a carrier spacecraft that will fly by Venus twice before releasing a descent probe. This probe will be protected by a heat shield and will enter the atmosphere, where it will gather data about the elemental properties of the Venusian atmosphere, image the landscape, and ultimately land on the surface.
The mission will utilize a special probe designed to handle extreme environmental changes, transitioning from super cold and low pressure to super hot and high pressure in a short period. This is a significant challenge, as Venus has a very dense atmosphere and extreme surface conditions.
