Astrotwins: Project Blastoff

Twins Mark and Scott Kelly are in big trouble when they take apart (aka destroy) their dad's calculator. Soon the twins decide on a loftier project. With the help of Jenny, nicknamed Egg, and a crew of can-do kids, they set out to build a real-live rocket that will blast off and orbit the Earth. The question soon becomes: Who will get launched into space?

Retired NASA astronaut and #1 New York Times bestselling author Mark Kelly's first novel is jam-packed with adventure, science, and laugh-out-loud sibling antics.
