Technical Session VII: Opportunities, Trends and Initiatives
Abstract
Small satellites offer the ability to demonstrate new technologies and missions at significantly lower cost than traditional large satellites. This study aims to provide data-driven answers to key questions about the historical usage of small satellites, such as: What types of missions are typically performed by spacecraft of different sizes? Are mission-focused spacecraft more successful than demonstration satellites? What is the impact of developer experience on mission success? The Aerospace Corporation used public sources to compile a database of nearly 250 small satellites launched between 2009 and 2013. Fourteen data points were collected for each mission, including physical characteristics and programmatics. These data were used to characterize these missions, and illustrate trends that influence how these vehicles will be used in the future. This study was able to answer key questions using historical experiences. These data showed that small satellites have become more capable and more successful over time. Science missions become increasingly viable at form factors as small as a 3U CubeSat. Typical development times for non-university CubeSat efforts are 18-24 months, but universities typically take at least twice as long. The probability of mission success is significantly higher for organizations that have previously developed at least two satellites.
