Assessing Programmatic Variables and Uncertainties in Space Exploration Campaign Planning
All space exploration programs begin life as a set of requirements, driven by one or more scientific or technological objectives. Historically, the majority of those objectives were achieved using tailor-made spacecraft and systems to deliver their payloads, be they science experiments or astronaut …

Market-Based Systems for Solving Space Exploration Resource Allocation Problems
The very nature of space exploration implies "doing that which has never been done before." As such, the resources needed to meet the objectives of such a grand endeavor, if available, are extremely scarce. Every mission since the birth of the space programme has been resource limited. To overcome …

Deep-Space Exploration Enabled by CubeSats with Staged Electrospray Propulsion
… and a capable tool for scientific missions. Deep-space CubeSats have been limited to rideshare launches thus far, acting as companions to enhance large missions or using propulsion to reach science orbits near the destination of the primary mission (e.g. to Mars or around the Moon). More CubeSat …
