Earth from Juno

On Oct. 9, Juno flew by Earth using the home planet's gravity to get a boost needed to reach Jupiter. The JunoCam caught this image of Earth, and other instruments were tested to ensure they work as designed during a close planetary encounter. The Juno spacecraft was launched from NASA's Kennedy Space Center in Florida on Aug. 5, 2011. Juno’s rocket, the Atlas 551, was only capable of giving Juno enough energy or speed to reach the asteroid belt, at which point the Sun’s gravity pulled Juno back toward the inner solar system. The Earth flyby gravity assist increases the spacecraft’s speed to put it on course for arrival at Jupiter on July 4, 2016. Image credit NASA/JPL-Caltech/Malin Space Science Systems

High Above Saturn

This portrait looking down on Saturn and its rings was created from images obtained by NASA's Cassini spacecraft on Oct. 10, 2013. It was made by amateur image processor and Cassini fan Gordan Ugarkovic. This image has not been geometrically corrected for shifts in the spacecraft perspective and still has some camera artifacts.The mosaic was created from 12 image footprints with red, blue and green filters from Cassini's imaging science subsystem. Ugarkovic used full color sets for 11 of the footprints and red and blue images for one footprint. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.
