Jupiter-Bound Spacecraft Changes its Orbit

  On August 30, navigators and mission controllers for NASA’s Juno mission to Jupiter watched their computer screens as their spacecraft successfully performed its first deep-space maneuver. This first firing of Juno’s main engine is one of two planned to refine the spacecraft’s trajectory, setting the stage for a gravity assist from a On August [continue reading]

Found: Two Planets Orbiting Around Two Suns

  A team of astronomers has found the first transiting circumbinary multi-planet system: two planets orbiting around a pair of stars. This discovery shows that planetary systems can form and survive even in the chaotic environment around a binary star. And that such planets can exist in the habitable zone of their stars. The results [continue reading]

Exploring the Chemistry of Mars

A researcher at The Open University in the UK will take part in a mission to explore the chemistry of Mars when Curiosity lands on the planet. The area where NASA’s Curiosity rover will land has a geological diversity that scientists are eager to investigate, as seen in this false-color map based on data from NASA’s [continue reading]

Ancient Meteorites Give New Clues to the Early Solar System

  In order to understand Earth’s earliest history–its formation from Solar System material into the present-day layering of metal core and mantle, and crust–scientists look to meteorites. The diogenites originated deep within the crust of Vesta and resemble rocks, both in texture and composition, which we find in the lower crust of the Earth. The [continue reading]
