In 1998, NASA’s Launch Services Program (LSP) was established to support NASA’s science and robotic missions by procuring commercial launch vehicles. The program was established at NASA’s Kennedy Space Center to centralize technical and management support to spacecraft customers. LSP brings together people, procurement, engineering best practices, strategic planning, studies, and cutting-edge techniques—all instrumental components for the United States to have a dependable and secure Earth-to-Space bridge that is dedicated to launching all types of spacecraft. This game goes through the process of a spacecraft matching to a rocket, the integration of the spacecraft to the rocket and the engineering behind it, and its eventual launch into space and the correct orbit. The game consists of 8 mini games to educate the player on the process Features: • Buying a rocket • How to get where you want to go in space • Analyzing the rocket and spacecraft • How to clean a spacecraft • Putting together a rocket • Time to fuel up • Frequency • Staying on target The characters that the player can choose from are represented by animals that are found in the Cape Canaveral Wildlife Refuge which encompasses Kennedy Space Center and Cape Canaveral Space Force Base. • Tortoise • Manatee • Wild hog • Bobcat • Alligator • T- Rex (not found in the Cape Canaveral Wildlife Refuge)
