NASA Venus Missions: What’s Finally Looking Up?
Yes—NASA’s long-awaited return to Venus is moving closer, with two missions selected for development: VERITAS and DAVINCI. But “finally looking up” means plans are advancing, not that either spacecraft has launched; schedules and budgets have changed, and both missions still face the work required to reach the planet and deliver their science.
Why Venus is back on NASA’s agenda
Venus is similar to Earth in size and likely formed from some of the same basic ingredients, yet it evolved into a radically different world. Its surface is hot enough to melt lead, its atmosphere is mostly carbon dioxide, and thick clouds hide the ground from ordinary cameras. Understanding how Venus became so inhospitable could help scientists explain why neighboring rocky planets followed different paths—and improve the study of Earth-sized planets around other stars.
NASA has not sent a dedicated mission to orbit or probe Venus since Magellan, which mapped the surface with radar in the early 1990s. The European Space Agency’s Venus Express and Japan’s Akatsuki have since contributed important observations, so Venus has not been entirely neglected. Still, the gap in NASA-led missions is unusually long for a planet that is Earth’s nearest neighbor.
What VERITAS will investigate
VERITAS—short for Venus Emissivity, Radio Science, InSAR, Topography, and Spectroscopy—is designed to orbit Venus and build a detailed picture of its surface and interior. Its radar will peer through the clouds, map surface features at high resolution, and measure changes in elevation. A near-infrared instrument will study the composition of surface materials through specific atmospheric windows.
Those observations can help researchers examine whether Venus has been volcanically active in recent geological times, how its surface formed, and whether its interior may still be moving heat. Radar images from Magellan revealed extensive volcanic landscapes, but their resolution and coverage leave major questions open. VERITAS would offer a much sharper, more comprehensive view, rather than simply taking ordinary photographs from above the clouds.
Radar measurements can also detect small changes in the distance between the spacecraft and the ground. Combined with gravity observations, these data can help scientists infer properties of the crust and interior. The mission is not designed to land: it would study the planet remotely from orbit.
What DAVINCI will investigate
DAVINCI, the Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging mission, takes a different approach. It includes an orbiter and a spherical descent probe that will fall through Venus’s atmosphere toward a mountainous region called Alpha Regio. During its descent, the probe will sample atmospheric gases and measure conditions such as temperature and pressure.
The measurements are important because Venus’s atmosphere preserves clues to the planet’s history. Ratios of noble gases and other chemical components can help researchers investigate how Venus formed, how much water it may once have had, and how its atmosphere changed over time. The probe is intended to transmit data during its descent; it is not a long-lived surface lander. The crushing pressure and extreme heat near the ground make prolonged operation there exceptionally difficult.
DAVINCI is also expected to take images of the surface as it descends, providing close-up views of terrain that orbiting radar cannot reproduce in the same way. Its orbiter will support the mission and make observations of Venus from space.
Why two missions are better than one
The missions address complementary questions. VERITAS maps the surface and investigates geology from orbit; DAVINCI directly samples the atmosphere and makes a brief, close approach to the ground. Scientists need both kinds of evidence to connect the planet’s present condition with its geological and atmospheric past.
- VERITAS: radar mapping, surface composition studies, topography, and clues about geological activity.
- DAVINCI: atmospheric chemistry, noble-gas measurements, descent observations, and close-up images.
They are not interchangeable, and neither mission is a search for life in the clouds. Venus’s cloud layer has attracted scientific interest, but these missions were selected to investigate the planet’s evolution, atmosphere, and geology—not to confirm a biological discovery.
What has slowed the return
NASA selected VERITAS and DAVINCI in 2021 as part of its Discovery Program, which supports relatively focused planetary science missions. Selection was a major step, but it did not mean the spacecraft were ready to fly. Mission teams still have to finish designs, build and test hardware, coordinate launch and operations, and stay within budgets and technical requirements.
VERITAS was delayed after NASA identified concerns involving workforce capacity and competing priorities. The delay affected its planned schedule and prompted independent review. NASA has subsequently worked to reestablish the mission’s path, but public schedule targets can shift as planning develops. DAVINCI also has a long development timeline before its planned launch and arrival. A proposed launch date should therefore be treated as a plan, not a guarantee.
Venus presents engineering challenges. Its thick atmosphere and cloud cover complicate observations, and the surface environment is hostile to landers. Spacecraft also need reliable thermal control, communications, and instruments that can operate through long periods of cruise and demanding observations. These difficulties help explain why a mission can be scientifically compelling and still take many years to prepare.
What “looking up” means now
The encouraging news is that NASA has active, defined Venus missions rather than only broad proposals: one focused on radar mapping and one on atmospheric sampling. The more cautious part is that a selection announcement is not a launch, and NASA’s schedule and funding decisions remain relevant to when the science will actually arrive.
NASA is not alone in renewing attention to Venus. Other space agencies have announced or planned Venus missions, reflecting wider interest in the planet. Their schedules and objectives are separate from NASA’s, however, and should not be confused with progress on VERITAS or DAVINCI. For NASA, the clearest milestones to watch are official updates on development, launch windows, and confirmed mission schedules.
Frequently Asked Questions
Has NASA launched a new mission to Venus?
No. VERITAS and DAVINCI have been selected for development, but neither has launched. Check NASA’s mission pages for current schedule updates.
When will VERITAS launch?
Its schedule has changed, and launch timing depends on NASA’s development plans and resources. Treat older target dates as outdated unless NASA confirms them in a current update.
What is the difference between VERITAS and DAVINCI?
VERITAS is an orbiter that will map Venus with radar and study its surface. DAVINCI will send a probe through the atmosphere to measure its chemistry and take descent images.
Why does NASA need radar to study Venus?
Thick clouds block ordinary visible-light views of the surface. Radar can pass through the cloud cover and reveal terrain, including mountains, plains, and volcanic features.
Will either mission look for life on Venus?
That is not the primary purpose of either mission. They are designed to investigate Venus’s geology, atmosphere, and evolution, which may inform broader questions about habitable worlds.
