Spacecraft on the Moon, lunar map
Spacecraft on the Moon. Map showing coloured markers for 34 spacecraft that impacted or landed on the Moon from the 1960s onwards. The spacecraft are: Ranger 7-9 (1964 to 1965, NASA, white), Luna 5, 7-9, 13, 15-18, 20-21, 23-24 (1965 to 1976, Soviet Union, red), Surveyor 1-7 (1966 to 1968, NASA, green), Lunar Orbiter 1-3 (1966 to 1967, NASA, black), Apollo 11-12, 14-17 (1969 to 1972, NASA, blue), Lunar Prospector (1999, NASA, pink) and SMART-1 (2006, ESA, white). All except the Apollo landers were unmanned probes. Luna 2 (1959) was the first man-made object to reach the surface of the Moon.

Canyon on Mars
Canyon on Mars. Artwork of fog in the Noctis Labyrinthus canyon on Mars in theearly morning. The fog forms when water ice on thecanyon walls is vaporised by the rising Sun. Highcirrus clouds create a halo (ring) around the Sun.On either side of the Sun are parhelia (sun dogs), bright spots caused by light refracting from highice crystals. Noctis Labyrinthus is a canyonsystem that is a tributary of the vast Valles Marineris, the largest canyon in the solarsystem.

Mars. Artwork of the planet Mars showingfeatures on its surface. At far left is thevolcano Olympus Mons. Standing 27 kilometres high, it is the largest volcano in the Solar System. Toits right are the three Tharsis Ridge volcanoes.From top to bottom, these are Arsia Mons, PavonisMons and Ascraeus Mons. To the right of thesethree volcanoes, the huge valley system VallesMarineris is seen running horizontally. The northpolar ice cap is seen at upper left. Mars is thefourth planet out from the Sun. It orbits some 228million kilometres from the Sun, taking just under687 days to complete one orbit.
