Abby and Kayla carefully planned their packing list before gathering the many items that they needed to undertake a space expedition. Abby's grandfather helped them build a rocket ship. The girls packed space suits to protect them from the extreme cold on the surface of Saturn. It was a bit tricky getting enough fuel for space exploration with their own money. Luckily, Gramps helped them get enough rocket fuel and soon they were ready for blast-off!
