NASA Press Release Text - June 24, 1996 GALILEO READY FOR CLOSE FLYBY OF JUPITER'S BIGGEST MOON Now residing in orbit around Jupiter, NASA's Galileo spacecraft is primed for its first close flyby of Jupiter's largest moon, Ganymede, at 2:29 a.m. EDT on June 27, 1996. ... In the days just before and after the Ganymede flyby, Galileo's other studies will include a search for auroral activity on Jupiter's nightside and observations of other Jovian moons: Io, Europa and Callisto. ...

In a game of ping-pong, suppose a paddle moves at 20 miles per hour and hits a ball with 20 mph in the opposite direction. ... In the new problem, a ball moving at -40 mph hits a non-moving surface; if the collision is elastic (no energy lost), that ball returns with the same speed but in the opposite direction, i.e. its velocity reverses sign. ... Something very similar happens when a spacecraft with velocity v passes close to a moving planet and is deflected. ...

Looking in the direction of the constellation Cygnus the Swan and launched by NASA in 2009 is the Kepler Space Observatory.Many previous missions searching for exoplanets mainly detected large giant planets, like large hot Jupiters (it is easier to detect larger planets).However KeplerтАЩs main objective is to search for much smaller planets located in a habitable zone which is not too close nor too far from their star; planets which may be just like our Earth. ...
