The Secret Science Society in Space

Mona is earth-bound.
Kiki is mission control.
Bart has a galactic space obsession.
And Zane's thinking is off the planet.
The Secret Science Society need to come up with a prize-winning experiment.
Will their excursion to the Planetarium be over the moon? Do they really build a rocket ship to put a dog in space? And will they solar-brate a win at the Science Expo?
With Zane's mystery modifications this can only mean one thing: An astronomical DISASTER! But ssssshhhhh, the ending is out of this world.
