Houston Williams was thrilled to win a scholarship to attend a space program at NASA. What he didn’t realize was that organizers were recruiting people for a top-secret research project aimed at studying how space travel affects people of different ages. After months spent on the International Space Station conducting a variety of experiments, Houston is surprised to learn that he and his two friends Ashley and Teal have been chosen to join a highly political mission to Mars. But after tragedy strikes, the teens are forced to continue the mission on their own. This is the third book in the Teen Astronauts series, following Houston, Is There A Problem? and Boldly Go.
Googol and Googolplex have come back to earth to continue their scavenger hunt. Tutus, sand dollars and peacock feathers are on their list. Luckily Troy and Pippa are ready to help, and the ocean is nearby, but so is Martin Kelly, the boy next door, who will ruin everything if he gets a chance.
Seven-year-old Ben loves pretending to be a robot, but his best friend Jessy is tired of being ordered to oil his knee joints and check his batteries. She says the robot game is boring and runs off to play with someone else. So Ben decides to build a real robot instead. He's built all kinds of things before: wind generators, solar-powered marble launchers, pinball machines. But none of his creations have ever really worked. Until now. When his robot begins talking, Ben is thrilled. However, nothing goes quite the way he thinks it will. Ben's robot is rather difficult to get along with. He complains a lot. He's bossy. He never wants to do anything Ben suggests. Having a real robot isn't nearly as much fun as Ben thought it would be. And to make things worse, no one - not even Jessy - will believe him.
