Space agencies around the world are setting their sights on new frontiers, with plans to explore Venus and other distant destinations in our solar system. These interplanetary missions are designed to answer some of humanity’s biggest questions: Are we alone in the universe?
How do planets evolve? Can humans live beyond Earth? Although Mars often takes the spotlight, Venus and other planets hold secrets that could reshape our understanding of the cosmos.
Venus is one of the most intriguing targets for exploration. Often called Earth’s twin because of its similar size and structure, Venus is also a cautionary tale about climate change. Its surface is a scorching 900°F (475°C), hot enough to melt lead, with an atmosphere full of carbon dioxide and clouds of sulfuric acid.
Despite these harsh conditions, scientists are fascinated by the possibility that life might exist in its upper atmosphere, where temperatures and pressures are more Earth-like.
In 2020, researchers detected phosphine, a gas that on Earth is often associated with biological processes, in Venus’s atmosphere. While the discovery remains controversial, it has sparked a renewed interest in exploring Venus more closely.
NASA is leading the charge with two upcoming missions to Venus: DAVINCI+ and VERITAS. Scheduled to launch later this decade, these missions aim to study Venus’s atmosphere and map its surface in unprecedented detail.
DAVINCI+ will send a probe to plunge through Venus’s thick clouds, measuring the gases and weather patterns as it descends. VERITAS will orbit the planet, using radar to create high-resolution maps of its surface and look for signs of past volcanic activity and water.
Together, these missions will help scientists understand why Venus became so inhospitable and whether Earth could face a similar fate.
Meanwhile, Europe and India are also preparing missions to Venus. The European Space Agency’s EnVision mission will focus on the planet’s geology and look for evidence of tectonic activity, while India’s Shukrayaan-1 will study the atmosphere and search for signs of lightning and other phenomena.
This international effort underscores the importance of Venus as a key to understanding rocky planets, including our own.
Beyond Venus, plans for interplanetary missions extend to even more distant destinations. Jupiter’s icy moon Europa and Saturn’s moon Titan are high on the list for exploration because they may harbor environments suitable for life.
NASA’s Europa Clipper mission, launching in 2024, will investigate Europa’s subsurface ocean, which lies beneath a thick crust of ice. Similarly, the Dragonfly mission, set to launch in 2027, will send a drone to Titan to study its surface and atmosphere.
Titan’s thick atmosphere and lakes of liquid methane make it one of the most intriguing places in the solar system.
Private companies are also joining the push for interplanetary exploration. SpaceX, founded by Elon Musk, has ambitious plans to send humans to Mars in the coming decades.
While Mars colonization often grabs headlines, SpaceX’s advancements in reusable rockets and spacecraft could support missions to other planets as well, making interplanetary travel more feasible and cost-effective.
These missions are not only about exploration but also about preparing for humanity’s future in space. Learning how to survive on harsh planets like Venus or Mars will provide the knowledge needed to establish permanent human settlements beyond Earth.
It’s a monumental challenge, but each step forward brings us closer to turning science fiction into reality.
The exploration of Venus and beyond represents humanity’s determination to push boundaries and seek answers to profound questions. These missions could uncover new insights into the history of our solar system, the potential for life elsewhere, and the future of humanity as a spacefaring species.
As we plan these journeys to our planetary neighbors, one thing is clear: the age of interplanetary exploration is just beginning, and the discoveries waiting for us could be extraordinary.
