The exoplanet is about half the mass of Jupiter, with a seemingly impossible, star-hugging orbit of only 4.2 Earth days. In 1995, scientists discovered 51 Pegasi b, forever changing the way we see the universe and our place in it. What will NASAx27 s Europa mission find when it heads for this intriguing moon in the 2020s. Tugging and flexing from Jupiterx27 s gravity generates enough heat to keep the ocean from freezing. NASAx27 s Cassini orbiter was designed to peer through Titanx27 s perpetual haze and unravel the mysteries of this planet-like moon. Fmb band saw parts manualįurther Cassini mission discoveries revealed strong evidence of a global ocean and the first signs of potential hydrothermal activity beyond Earth making this tiny Saturnian moon one of the leading locations in the search for possible life beyond Earth. NASAx27 s Juno mission will observe Jupiterx27 s auroras from above the polar regions, studying them in a way never before possible. Revolving outside this auroral oval are the glowing, electric footprints of Jupiterx27 s three largest moons. Jupiterx27 s auroras are hundreds of times more powerful than Earthx27 s, and they form a glowing ring around each pole thatx27 s bigger than our home planet. It is the largest object in the main asteroid belt between Mars and Jupiter, with an equatorial diameter of about 965 kilometers.Īfter being studied with telescopes for more than two centuries, Ceres became the first dwarf planet to be explored by a spacecraft, when NASAx27 s Dawn probe arrived in orbit in March 2015.ĭawnx27 s ongoing detailed observations are revealing intriguing insights into the nature of this mysterious world of ice and rock. Spacecraft now allow us the luxury to study these cosmic crossings at times of our choosing from unique locales across our solar system. JPLx27 s Earth science missions monitor our home planet and how itx27 s changing so it can continue to provide a safe haven as we reach deeper into the cosmos. Warm, wet and with an atmosphere thatx27 s just right, Earth is the only place we know of with life and lots of it.
This poster imagines a future day when we have achieved our vision of human exploration of Mars and takes a nostalgic look back at the great imagined milestones of Mars exploration that will someday be celebrated as historic sites. Missions like Mars Pathfinder, Mars Exploration Rovers, Mars Science Laboratory and Mars Reconnaissance Orbiter, among many others, have provided important information in understanding of the habitability of Mars.
Today both Voyager spacecraft continue to return valuable science from the far reaches of our solar system. Voyager set the stage for such ambitious orbiter missions as Galileo to Jupiter and Cassini to Saturn.
