NASA Releases 'Vintage' Space Tourism Posters

NASA's Voyager mission took advantage of a once-every-175-year alignment of the outer planets for a grand tour of the solar system. JPL/NASA

NASA's Mars Exploration Program seeks to understand whether Mars was, is, or can be a habitable world. Missions like Mars Pathfinder, Mars Exploration Rovers, Mars Science Laboratory and Mars Reconnaissance Orbiter, among many others, have provided important information in our understanding of the habitability of Mars.

JPL's Earth science missions monitor our home planet and how it's changing so it can continue to provide a safe haven as we reach deeper into the cosmos.JPL/NASA

The rare science opportunity of planetary transits has long inspired bold voyages to exotic vantage points – journeys such as James Cook's trek to the South Pacific to watch Venus and Mercury cross the face of the Sun in 1769.JPL/NASA

Ceres is the closest dwarf planet to the Sun. It is the largest object in the main asteroid belt between Mars and Jupiter, with an equatorial diameter of about 965 kilometers.JPL/NASA

The Jovian cloudscape boasts the most spectacular light show in the solar system, with northern and southern lights to dazzle even the most jaded space traveler. JPL/NASA

The discovery of Enceladus' icy jets and their role in creating Saturn's E-ring is one of the top findings of the Cassini mission to Saturn. Further Cassini mission discoveries revealed strong evidence of a global ocean and the first signs of potential hydrothermal activity beyond EarthJPL/NASA

Frigid and alien, yet similar to our own planet billions of years ago, Saturn's largest moon, Titan, has a thick atmosphere, organic-rich chemistry and a surface shaped by rivers and lakes of liquid ethane and methane. JPL/NASA

Beneath its icy surface, Europa is believed to conceal a global ocean of salty liquid water twice the volume of Earth's oceans. JPL/NASA

In 1995, scientists discovered 51 Pegasi b, an exoplanet about half the mass of Jupiter. Not only was it the first planet confirmed to orbit a sun-like star, it also ushered in a whole new class of planets called Hot Jupiters: hot, massive planets orbiting closer to their stars than Mercury. JPL/NASA

Twice as big in volume as the Earth, HD 40307g straddles the line between "Super-Earth" and "mini-Neptune" and scientists aren't sure if it has a rocky surface or one that's buried beneath thick layers of gas and ice. JPL/NASA

Like Luke Skywalker's planet "Tatooine" in Star Wars, Kepler-16b orbits a pair of stars. Depicted here as a terrestrial planet, Kepler-16b might also be a gas giant like Saturn. JPL/NASA

Kepler-186f is the first Earth-size planet discovered in the potentially 'habitable zone' around another star, where liquid water could exist on the planet's surface. Its star is much cooler and redder than our Sun.JPL/NASA

Discovered in October 2013 using direct imaging, PSO J318.5-22 belongs to a special class of planets called rogue, or free-floating, planets. Wandering alone in the galaxy, they do not orbit a parent star.JPL/NASA
