It is composed of the orbiter module, which carries 11 scientific experiments, and a lander , dubbed Philae , with 10 additional experiments, with which the most detailed study ever carried out on a comet will be developed.
According to ESA sources, Rosetta's name comes from the famous stone that made it possible to decipher Egyptian hieroglyphs about 200 years ago. Scientists are hoping that this space mission will unravel the mysteries of the evolution of the Solar System. Launched in March 2004, its importance lies in the fact that it focuses on its research on comets, since they are considered the objects that have been least modified in the Solar System, since they were formed approximately 4,600 million years ago.
Most of the comet's surface is made up of rocks, some about the size of a house, and with steep slopes, deep trenches, and large cliffs. As a curious fact, this mission covers a total cost of about one billion euros , to which an additional 70 million were added due to the delay in its launch (it was scheduled for January 2003).
