Jupiter is, quite literally, the biggest mystery in the solar system. But that will hopefully change after the launch of NASA's Juno mission on Friday. About 15 years ago, NASA's Galileo mission revealed curious inconsistencies in the planet's atmosphere. Models of the solar system suggest Jupiter formed near its current location, just outside the solar system's "frost line", a boundary beyond which water vapour condenses. Yet when Galileo launched a probe into the planet's atmosphere in 1995, the probe found surprisingly little water. Read more
Nasa's $1.1bn (£0.7bn) Juno mission will venture where no solar-powered spacecraft has dared go before. The probe, due to launch from Cape Canaveral on Friday, will cruise beyond Mars to put itself in orbit around the gas giant Jupiter in 2016. Read more
Juno Jupiter Mission to Carry Plaque Dedicated to Galileo
A plaque dedicated to the famous astronomer Galileo Galilei will be carried to Jupiter aboard NASA's Juno spacecraft. The launch period for Juno opens Aug. 5, 2011, and extends through Aug. 26. For an Aug. 5 liftoff, the launch window opens at 8:34 a.m. PDT (11:34 a.m. EDT) and remains open through 9:43 a.m. PDT (12:43 p.m. EDT). Among his many achievements, Galileo Galilei discovered that moons orbited Jupiter in 1610. These satellites -- Io, Europa, Ganymede and Callisto -- are also known as the Galilean moons. Read more
Juno Spacecraft to Carry Three Figurines to Jupiter Orbit
NASA's Jupiter-bound Juno spacecraft will carry the 1.5-inch likeness of Galileo Galilei, the Roman god Jupiter and his wife Juno to Jupiter when the spacecraft launches this Friday, Aug. 5. The inclusion of the three mini-statues, or figurines, is part of a joint outreach and educational program developed as part of the partnership between NASA and the LEGO Group to inspire children to explore science, technology, engineering and mathematics. In Greek and Roman mythology, Jupiter drew a veil of clouds around himself to hide his mischief. From Mount Olympus, Juno was able to peer through the clouds and reveal Jupiter's true nature. Juno holds a magnifying glass to signify her search for the truth, while her husband holds a lightning bolt. The third LEGO crew member is Galileo Galilei, who made several important discoveries about Jupiter, including the four largest satellites of Jupiter (named the Galilean moons in his honour). Of course, the miniature Galileo has his telescope with him on the journey. Read more
Final preparations for the roll out of an Atlas V rocket are under way today at Cape Canaveral Air Force Station as NASA and United Launch Alliance gear up for launch Friday of a $1.1 billion mission to Jupiter. Read more
