Projects

Cassini-Huygens Icon Cassini-Huygens
The Cassini-Huygens spacecraft explored the ringed planet, its mysterious moons, the stunning rings and its complex magnetic environment.

Juno Icon Juno
Juno is in 53-day polar orbits, observing Jupiter in order to understand the planet's gross size and structural properties, as well as measuring its atmospheric composition, temperature and deep wind profiles.

New Horizons Icon New Horizons
New Horizons is the first mission in NASA's New Frontiers program of medium-class planetary missions. It will be the first spacecraft to visit Pluto and its moon Charon.

Venus Express Icon Venus Express
Venus Express is the European Space Agency's first mission to Earth's nearest planetary neighbor, Venus.
