Space Transportation Systems for the Future

Future space transportation systems will include the improved Space Shuttle, new and derivative cargo launch vehicles, new propulsion systems, orbital transfer and maneuvering vehicles, and a second generation Shuttle. More efficient and capable systems must be developed by placing strong emphasis on high reliability, safety, and improved ground and flight operations. These improvements can be accomplished by introducing advanced technologies and vehicles designed for operations and maintainability with the flexibility to adapt to mission needs. A summary of the potential requirements, proposed configurations, inherent development problems, and technologies to be considered for future space transportation systems are presented here.
