When one of Pom Pom's botany experiments goes awry on the International Space Station, the CatStronauts must find a way to tame the weeds gone haywire and get back to Earth without help from Mission Control.

Alerted to a global energy crisis, the President consults with the World's Best Scientist, who suggests sending a special group of astronauts to turn the Moon into a solar power plant.

"With national pride and valuable scientific research on the line, the CatStronauts race against the CosmoCats and others to be the first cats to Mars"--

"The CatStronauts--elite cat astronauts--are aboard the International Space Station to repair the faulty Hubba Bubba Telescope, but have to contend with communications interference and a near disaster that leaves them down a member"--

When Cat-Stro-Bot gets into trouble while helping the CatStronauts team with their research on Europa, the CatStronauts defy mission control and undertake a secret mission to save their friend on Jupiter's frozen moon.

"Darby Fuzzelton, the world's richest cat, is determined to open the first-ever space hotel! Her first guests? The elite CatStronauts along with a few kittens who were top of their class at Space Camp. Their job? To prove that her space hotel is safe to the public. When the cats and kittens arrive, they're greeted by AVA, an advanced Artificial Intelligence system programmed to handle countless hotel operations. Upon seeing Cat-Stro-Bot and his ability to go ANYWHERE, AVA becomes obsessed with gaining her own freedom. With AVA distracted, all the hotel systems go on the fritz! Will the CatStronauts escape this hotel of horrors?"-- Back cover.

"When the CatStronauts shuttle launch is delayed, Waffles and Pancake take matters into their own hands and build a spaceship"--

Future CatStronaut Waffles and his younger sister Pancake are kittens who enjoy visiting the science museum with Dad-Cat.--

"Waffles and Pacake are about to spend three days at Space Cat Camp--a fun, science-packed training experience for future CatStronauts. What's not to love about Space Cat Camp? You get to go on cool missions, build rockets, and more! Pancake can't wait to learn about satellites, space shuttles, and all things outer space, but Waffles is feeling a little homesick. How can he enjoy his time at camp when he misses his dad-cat? With some new friends and the power of teamwork, these kittens will be ready to pounce on any challenges ahead."--

Waffles, Pancake, and Mom-Cat go to visit Gramps and Grammers, but this is the kittens' first time flying on an airplane, and Waffles is a little nervous.
