- 15 December 1970Venera 7 Lands on Venus
The Soviet Venera 7 transmits from the surface of Venus, the first successful landing on another planet.
- December 1972Apollo 17, the Last Crewed Moon Landing
The final Apollo landing; Eugene Cernan is, to date, the last person to walk on the Moon, and geologist Harrison Schmitt the only scientist to do so.
Viking 1 was the first spacecraft to land and operate successfully on the surface of Mars.

Viking 1 becomes the first spacecraft to operate successfully on the surface of Mars, returning the first pictures from the Martian ground and searching for life.
- 25 August 1989Voyager 2 Flies Past Neptune
Voyager 2 sweeps past Neptune, the first and only spacecraft to visit the ice giant, completing the reconnaissance of every planet from Mercury to Neptune.
- December 1995Galileo Arrives at Jupiter
Galileo becomes the first spacecraft to orbit Jupiter and drops a probe into its atmosphere, beginning years of study of the giant planet and its moons.
Sojourner, delivered by Mars Pathfinder, was the first wheeled rover to operate on another planet.
- 4 July 1997Mars Pathfinder and Sojourner
Mars Pathfinder lands using airbags and deploys Sojourner, the first successful rover on another planet, proving a low-cost path back to the Martian surface.
- 1 July 2004Cassini Arrives at Saturn
Cassini enters orbit around Saturn and later delivers the Huygens probe to Titan, beginning thirteen years of discovery in the Saturn system.
- 4 July 2005Deep Impact Strikes Comet Tempel 1
Deep Impact fires a projectile into comet Tempel 1, excavating fresh material to reveal what a comet is made of.
- November 2005Hayabusa Samples Asteroid Itokawa
Japan's Hayabusa touches down on the asteroid Itokawa; despite great difficulties it returns to Earth in 2010 with the first samples ever collected from an asteroid.
Hayabusa returned the first samples ever collected from an asteroid, from Itokawa, to Earth.
- 6 August 2012Curiosity Lands on Mars
The car-sized Curiosity rover lands in Gale Crater using the daring sky-crane manoeuvre, beginning a long study of Mars's ancient habitability.
Rosetta's Philae lander made the first soft landing on the nucleus of a comet.
ESA's Rosetta becomes the first spacecraft to orbit a comet and, with its Philae lander, the first to soft-land on one — comet Churyumov–Gerasimenko.
- 14 July 2015New Horizons Flies Past Pluto
After a nine-year journey, New Horizons sweeps past Pluto, revealing an astonishingly varied world and completing the first reconnaissance of the classical Solar System.
Within months of each other, Japan's Hayabusa2 delivers samples of asteroid Ryugu to Earth and NASA's OSIRIS-REx collects a sample from asteroid Bennu, opening a new age of asteroid sample return.
The Ingenuity helicopter made the first powered, controlled flight by an aircraft on another planet.
The tiny Ingenuity helicopter, carried by the Perseverance rover, lifts off from the surface of Mars — the first powered, controlled flight on another planet.
- 23 August 2023Chandrayaan-3 Lands Near the Lunar South Pole
India's Chandrayaan-3 makes a soft landing near the Moon's south pole, making India the fourth nation to land on the Moon and the first near the south-polar region.
