"Here is the amazing true story of how a single piece of cloth-originally destined to become underwear-was used in the design of the Wright brothers' Flyer, traveled to the Moon with Apollo 11, and is currently wandering Mars on Ingenuity"--.

"Interplanetary space explorers Rover and Speck have set out on a dangerous mission deep into the mysterious unknown: a visit to Unexplored Planet K2-18b. Though all seems calm to Rover when they first splash down on the watery surface, they soon find themselves in the mouth of a gigantic blubber beast! With a little ingenuity (by Rover) and some furious paddling (by Speck) they manage to escape unharmed. But when the pair meet two local spikey-spikes whose brother was swallowed by the Beast, Rover knows the brother's only hope is for the two brave explorers to go back inside the Beast to find him. Do Rover and Speck have what it takes to rescue the spikey-spike? Or will they--gulp--get swallowed, too?"--Provided by publisher.

"Rover and Speck couldn't be more different. Rover is organized, careful, and on a mission to explore the far reaches of the galaxy. Speck is impulsive, excitable, and stranded alone on a rocky planet. But these two rovers have to team up when Rover crash lands and helps Speck recharge his battery. Together, they can explore the planet and gather tons of cool scientific data! That is, if the strange rock creatures chasing them don't get to them first"--Provided by publisher.

"It's October in space, and Bob is getting excited for his favorite holiday: Halloween. When Bob tells Beep that soon they'll get to dress up like monsters and get as much free candy as they can carry, Beep thinks he has gone to heaven. But Lani informs them that Halloween isn't celebrated at Astro Elementary. Bob cannot imagine life without Halloween! He appeals to Principal Quark, but with no success. Determined to save Halloween, Bob and Lani organize a secret club: S.C.A.R.E.S. (Society of Candy Addicts who Rely on Energy from Sugar). As the secret club grows, Halloween fever invades Astro Elementary. Unfortunately, a horde of grotesque aliens, attracted by the treats, also invades the school on the last day of the month. With everyone in costume, no one can tell who's who. Beep and Bob may have saved the holiday, but can they somehow use their sugar-addled wits to save the school?"--Publisher's description.

"While working on his duplication ray, Bob accidentally makes clones of himself and his alien friend Beep, and soon finds out that their doubles are evil and plan to rule the Earth"--OCLC.
