there's a feisty little spacecraft called GALILEO exploring the giant planet Jupiter RIGHT NOW?! |
As we sit here, Spacecraft Galileo is soaring
Past Jupiter and its big moons,
At thousands of miles per hour
Taking lots of pictures and
Learning all about these strange worlds
To tell us back here on Earth!
Galileo is a very special orbiting spacecraft, built at the Jet Propulsion Lab (JPL) in California, just like Mars Pathfinder and its rover, Sojourner, who are at Mars now. | |
But while Pathfinder left for Mars just a few years ago, Galileo left Earth way back in 1989! And Galileo didn't arrive at Jupiter until December of 1995. What was Spacecraft Galileo doing in space for those six years? | |
Find out by reading Galileo's six-year Journey to Jupiter, which tells how Galileo had to take the "long way" to Jupiter to save fuel, but how it ended up having lots of adventures along the way. | |
Spacecraft Galileo has had a very successful mission, but the little spacecraft was not without its problems. One *serious* problem was with its big antenna. The big antenna was stowed away for launch, and it wasn't until Galileo was in space that it discovered ... well, you should read the WHOLE story at Galileo's Greatest Challenge, and see how Galileo and its support crew conquered their worst nightmare. | |
After six years of adventures and scary equipment problems, Galileo reached Jupiter! Now Galileo had to allow itself to be caught in Jupiter's gravity pull, not an easy feat! Galileo's riding companion, the Probe, shot into Jupiter to send back information about the clouds there. Would Galileo start orbiting Jupiter, as planned? What would the Probe find? What's it like to orbit a giant planet like Jupiter and skim past its strange moons for two years? Find out at Galileo meets Jupiter and the Moons. | |
Spacecraft Galileo RIGHT NOW is zooming around and round past Jupiter's strange moons Europa, Ganymede, and Callisto. The main mission is over, but the little spacecraft is doing so well, its mission has been extended! For two more years, Galileo will take many pictures of Europa, so we can see more of its frozen surface. Europa may have life under its icy crust! And Galileo still wants to take pictures of Io after that. | |
