Could we send a space mission to a comet?
I recall reading an Arthur Clarke novel titled "2061". The novel revolved around a manned mission to interface with Halley's Comet. How feasible is such a mission?
We have actually already sent a spacecraft to Halley's comet. During the mid 1980s Halley made one of its visits to the inner solar system and five spacecraft were sent to intercept it. The most famous was called Giotto.
Since then, we have sent several missions to comets. In 1999, NASA launched Stardust, which traveled through the coma (part of the tail) of comet Wild 2 and returned samples to Earth in 2006.
NASA's Deep Impact spacecraft was launched in January 2005 and reached the comet Tempel 1 on July 4, 2005. Deep Impact was the first mission to blast a crater in a comet and observe the results! The mission revealed that the comet was much dustier and less icy than expected. The Stardust mission will fly-by Tempel 1 in 2014 to photograph the crater, while Deep Impact travels on to observe comet Boethin sometime in the next decade.
Finally, the European Space Agency's Rosetta mission, launched in 2004, will orbit and land on a comet sometime in 2014.
