Missions to comets

Giotto was a European robotic spacecraft mission from the European Space Agency.

Vesta was a multiple-asteroid-flyby mission that the Soviet Union was planning in the 1980s.

The International Cometary Explorer (ICE) spacecraft (designed and launched as the International Sun-Earth Explorer-3 (ISEE-3) satellite), was launched August 12, 1978, into a heliocentric orbit.

Philae (/ˈfaɪliː/ or /ˈfiːleɪ/) is a robotic European Space Agency lander that accompanied the Rosetta spacecraft until it separated to land on comet 67P/Churyumov–Gerasimenko, ten years and eight months after departing Earth.

Ulysses is a decommissioned robotic space probe whose primary mission was to orbit the Sun and study it at all latitudes.

Deep Space 1 (DS1) is a spacecraft of the NASA New Millennium Program dedicated to testing a payload of advanced technologies.

Stardust was a 300-kilogram robotic space probe launched by NASA on February 7, 1999.

Deep Impact was a NASA space probe launched from Cape Canaveral Air Force Station at 18:47 UTC on January 12, 2005.

Sakigake (さきがけ lit. "pioneer" or "pathfinder"), known before launch as MS-T5, was Japan's first interplanetary spacecraft, and the first deep space probe to be launched by any country other than the USA or the Soviet Union.

This is a list of all space probes that have left Earth orbit (or were launched with that intention but failed), organized by their planned destination.

Pioneer 6, 7, 8, and 9 were space probes in the Pioneer program.

Suisei (すいせい; Japanese for Comet), originally known as Planet-A, was an unmanned space probe developed by the Institute of Space and Astronautical Science (now part of the Japanese Aerospace Exploration Agency, or JAXA).

EPOXI is a compilation of NASA Discovery program missions led by the University of Maryland and principal investigator Michael A'Hearn, with co-operation from the Jet Propulsion Laboratory and Ball Aerospace.

The COmet Nucleus TOUR (CONTOUR) was a NASA Discovery-class space probe that failed shortly after its July 2002 launch.

Comet Hopper (CHopper) was a proposed lander to NASA's Discovery Program that, had it been selected, would have orbited and landed multiple times on Comet Wirtanen as it approaches the Sun.
