SPRITE MINI-LIFT, AN AFFORDABLE SMALL EXPENDABLE LAUNCHER*

Small, mini, micro-, and nano-satellite technologies are leading to many innovative space applications. A primary obstacle to successful operational transition of these systems is the lack of affordable small launch capability. This paper covers the design concept, technologies, production, and operational characteristics of an all-new generation launch system that will substantially lower the cost of a dedicated small spacecraft launch. A unique combination of low cost technologies, design and manufacturing approaches enable the Scorpius® Sprite launcher to deliver 700 Ib. payloads to low Earth orbit (LEO) for 20% of the cost of the lowest cost U.S. launch now available. The Sprite vehicle architecture employs similar propulsion "pods" for the first and second stages. Simple pressure-fed engines using LOX and jet fuel power all three Sprite stages. Finally, the scalability of the Scorpius® launch system architecture and technologies enable larger low cost launchers as well. With a low vehicle production cost, the need for low operations and range costs gains importance. Consequently, simplified operations and range interfaces are being developed for Sprite to reduce operational complexity.
