Michael RubensteinNorthwestern University, Chicago We propose a mission to use ~10,000 actively steerable femtosats to map the ring composition, atmospheric composition and density, and the magnetic field distribution of Saturn. Conducting in-situ surveys of Saturn’s rings with a single flagship mission, such as Cassini, would carry an unacceptably high risk of mission failure due to […]

PRAXIS: Planetary Rings Autonomous EXploration with In-situ Sampling
Marco QuadrelliNASA Jet Propulsion Laboratory Humanity has never touched the particles of a planetary ring, but if we were able to get close enough and sample them, it will transform understanding of ring structure and origins for Saturn (dense), Uranus and Neptune (tenuous), rings of other objects such as Centaurs Chariklo and Chiron, and even early […]

ECLIPSE – Efficient variable Conductivity Lunar Insulator for Passive Surveyor Environmental control
Austin Phoenix Virginia Polytechnic Institute & State A disaggregated lunar infrastructure requires novel thermal management methods to enable future lunar operations. While thermal management solutions exist for large infrastructure, the smaller mobile systems that operate independently require improved temperature regulation devices that can survive without heaters or substantial power requirements, while limiting stress-inducing temperature fluctuations. New […]
Plasmon-Enhanced Radioisotope Thermophotovoltaic (PRTPV) Power Generation for Interstellar Missions
Keunhan ParkUniversity of Utah This proposal seeks to develop a transformative energy system — the plasmon-enhanced radioisotope Thermophotovoltaic (PRTPV) generator — that significantly surpasses the performance of current radioisotope thermoelectric generators (RTGs) in both specific power and efficiency. Designed to achieve a specific power of 17 W/kg and a thermal-to-electric conversion efficiency greater than 40%, […]

Autonomous Tritium Micropowered Sensors
Peter CabauyCity Labs, Inc. The NIAC Phase I study confirmed the feasibility of nuclear-micropowered probes (NMPs) using tritium betavoltaic power technology for autonomous exploration of the Moon’s permanently shadowed regions (PSRs). This work advanced the technology’s readiness level (TRL) from TRL 1 to TRL 2, validating theoretical models and feasibility assessments. Phase II will refine […]
Addressing Key Challenges To Mapping Sub-cm Orbital Debris in LEO via Plasma Soliton Detection
Christine HartzellUniversity of Maryland, College Park The proposed investigation will address key technological challenges associated with a previously funded NIAC Phase I award titled “On-Orbit, Collision-Free Mapping of Small Orbital Debris”. Sub-cm orbital debris in LEO is not detectable or trackable using conventional technologies and poses a major hazard to crewed and un-crewed spacecraft. Orbital […]
Breathing Beyond Earth: A Reliable Oxygen Production Architecture for Human Space Exploration
Alvaro Romero-CalvoGeorgia Tech Research Corporation The reliable and efficient operation of spacecraft life support systems is challenged in microgravity by the near absence of buoyancy. This impacts the electrolytic production of oxygen and hydrogen from water by forcing the adoption of complex multiphase flow management technologies. Still, water splitting plays an essential role in human […]
TFINER – Thin Film Isotope Nuclear Engine Rocket
James BickfordCharles Stark Draper Laboratory, Inc. The Thin-Film Nuclear Engine Rocket (TFINER) is a novel space propulsion technology that enables aggressive space exploration for missions that are impossible with existing approaches. The concept uses thin layers of energetic radioisotopes to directly generate thrust. The emission direction of its natural decay products is biased by a […]
