Firefly was established to provide low-cost, high-performance space launch capability for the under-served small satellite market, where secondary-payload launches are often the only option. The technologies employed in their state-of-the-art rockets provide a clear pathway for future incremental improvements in vehicle capability. Later vehicles will also have reusable elements and employ air-breathing propulsion. Small satellites are playing an increasingly significant role in space. Smaller, lighter and cheaper satellite technologies have led to functional systems that are a fraction of the size of their predecessors. Meanwhile, constellations of small satellites are showing promise for replacing larger custom-built systems, thus providing redundancy and the ability to regularly refresh system technology. Lastly, many advanced technologies languish at middle TRL levels. Low cost rides to space will allow these technologies to be proven and advance their collective space-flight capabilities.
