Astrotwins -- Project RescueHardcover, 1 March 2016

Twins Mark and Scott discover an abandoned Apollo command module and take off to rescue a stranded Russian cosmonaut in the second Astrotwins adventure from retired NASA astronaut and the #1 New York Times bestselling author of Mousetronaut, Mark Kelly.

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?

Written by a NASA astronaut with four space flights under his belt, the second exciting Astrotwins story includes extensive back matter on the space program with fantastic facts and details.
