Next-generation space transportation

NASA narrows its search for a successor to the Space Shuttle.

NASA is another step closer to defining the next-generation reusable space transportation system. The first review of the Space Launch Initiative (SLI), a NASA-wide effort defining future space transportation systems, has been completed, narrowing the field of potential candidates for a new space transportation system.

Dependable, long-life engines, along with crew escape and survival systems, and long-life, lightweight integrated airframes are among the SLI's highest priorities. Each greatly impacts the program's bottom line of increased safety, reliability, and cost-effectiveness.
