Slippy is excited to try out his new Rocket Boosters. So excited that he overloads them and crashes on Jupiter’s moon with Madhu. Slippy is not worried about fixing his racer so sends Madhu back to see Ella. Slippy’s easy fix turns out not to be. He calls for help, but is cut off before he can say where he is. When Madhu discovers there are at least 79 Jupiter moons, finding Slippy becomes much harder. Madhu uses the process of elimination to narrow the choice down in time to save Slippy from a volcano eruption!

The year is 3021. The place is the Milky Way, where eight-year-old Ella gleefully heads out with her friends on exciting adventures of discovery. At only eight, she already knows quite a bit about space... but there is always more to explore!
