Twins Mark and Scott discover an abandoned Apollo command module and take off to rescue a stranded Russian cosmonaut in the second Astrotwins adventure.

Mark and Scott Kelly, who are mostly known for getting in trouble, are finally back from their first space adventure. The twins have wanted to explore space ever since they were little and watched Neil Armstrong walk on the moon. And when they hear that a Russian cosmonaut is trapped inside the Salyut space station now orbiting 220 miles above the surface of the Earth, they wish they could find a way to help.

While staying in the countryside at their grandfather’s house with their friend Jenny (aka Egg), the twins repurpose a NASA Titan 2 rocket ship being stored nearby. Complete with spacesuits and snacks, the twins take off to rescue the Russian spacecraft. Will they ever see their family or their grandfather’s backyard again?
