Little is known of what people thought about comets before Aristotle, who observed his eponymous comet, and most of what is known comes secondhand.From cuneiform astronomical tablets, and works by Aristotle, Diodorus Siculus, Seneca, and one attributed to Plutarch but now thought to be Aetius, it is observed that ancient philosophers divided themselves into two main camps.
The first human to walk on the surface of another Solar System body was Neil Armstrong, who stepped onto the Moon on July 21, 1969 during the Apollo 11 mission; five more Moon landings occurred through 1972. The United States' reusable Space Shuttle flew 135 missions between 1981 and 2011. Two of the five shuttles were destroyed in accidents.

ICE transited between the Sun and Comet Halley in late March 1986, when other spacecraft were near the comet on their early-March comet rendezvous missions. (This "Halley Armada" included Giotto, Vega 1 and 2, Suisei and Sakigake.) ICE flew through the tail; its minimum distance to the comet nucleus was 28 × 10 ^ 6 km (17 × 10 ^ 6 mi). [19]
Galileo 's prime mission was a two-year study of the Jovian system, but on March 26, 1993, while it was en route, astronomers Carolyn S. Shoemaker, Eugene M. Shoemaker and David H. Levy discovered fragments of a comet orbiting Jupiter, the remains of a comet that had passed within Jupiter's Roche limit and had been torn apart by tidal forces.

EPOXI mission observation of Hartley 2's jets. The Deep Impact mission was finished with the visit to comet Tempel 1.But the spacecraft still had plenty of maneuvering fuel left, so NASA approved a second mission, called EPOXI (Extrasolar Planet Observation and Deep Impact Extended Investigation), which included a visit to a second comet (DIXI component) as well as observations of extrasolar ...
