Because I Love This Planet.Survive has detected the gravity storm approaching, on a direct collision course with the planet, due to arrive in three days. Shingo thinks they can save the planet by using the gravity control unit on Survive's spaceship to create an inverse gravity field, cancelling out the gravity storm. With Survive's computing power, the children test a simulation using the anti-gravity sled's smaller unit, and are successful. However, since the plan requires detaching the gravity control unit from Survive's ship and sending it into the storm, Howard and Menori object, saying they should use the ship to return home while they can - there are no other spaceships or sufficiently powerful gravity control units on the planet...
