Themes
The themes of future exploration — the Moon, Mars, Venus, the ocean worlds, small bodies, observatories, and the outer Solar System.
- Lunar ExplorationTheme
The return of humans to the Moon and the build-out of a sustained presence — the Artemis crewed missions and the Gateway station in lunar orbit.
- Mars ExplorationTheme
The next steps at Mars — returning the samples now being cached by Perseverance, studying the moons of Mars, and preparing for human missions.
- Venus ExplorationTheme
A renaissance at Venus — a fleet of new missions to map its surface, sound its atmosphere, and understand why Earth's twin became a hell-world.
- Ocean WorldsTheme
The search for habitable environments in the outer Solar System — the subsurface oceans of Europa and the seas and organic chemistry of Titan.
Future missions to asteroids and comets — for science and for planetary defence, including surveys to find the hazardous near-Earth objects before they find us.
The great observatories of the coming decades — surveying dark energy, imaging habitable worlds, and opening the low-frequency gravitational-wave and X-ray skies.
- Outer Solar SystemTheme
Reaching the least-explored worlds — an orbiter for an ice giant, and a probe designed to travel deliberately beyond the heliosphere into interstellar space.
