Discovery and exploration of the Solar System Earth to be orbited by an artificial satellite ("Luna 10"), followed by Mars in 1971 ("Mariner 9"), Venus in 1975 ("Venera 9"), Jupiter in 1995 ("Galileo"), the asteroid 433 Eros in 2000 ("NEAR Shoemaker"), Saturn in 2004 ("Cassini–Huygens"), and Mercury and Vesta in 2011 ("MESSENGER" and "Dawn" respectively). "Dawn" is orbiting the asteroid–dwarf planet Ceres as of 2015. The first probe to land on another Solar System body was the Soviet "Luna 2" probe, which impacted the Moon in 1959.

Stranger from Venus field. This disruption would then affect the orbits and gravitational fields of all the other planets in the solar system. The stranger makes a promise that if Earth eliminates these dangers, Venus will share some of its higher scientific knowledge with our scientists. During the meeting, however, the man from Venus concludes that humanity is not yet ready to receive such advanced knowledge. After his communication disc is stolen, which allows him to contact the approaching Venusian ship, the stranger quickly realizes that an interplanetary meeting of minds can never take place.
