It's 2162 and life is a blast for space adventurer siblings, Jet and Adelaide Nova. After all, what tween wouldn't want to divide their days between living on an international space station and accompanying their parents on awesome interstellar missions. Of course it's not all asteroid chases and exploding star systems. Jet and Adelaide also have to attend school, do homework (though their chores aren't always so typical, like recharging the family robot and scrubbing their star ships hull!). Still, on weekends this Aussie astronaut family have their own unique way of unwinding, with Jet and Adelaide heading off with parents Hugo and Josie on mind blowing adventures to navigate unexplored planets, surf solar flares, hop between rogue stars and occasionally even discover previously unknown life forms.
