Photophoretic Tracers for Near-Space Remote Sensing at 30-100 km Altitudes 
Photophoretic Tracers for Near-Space Remote Sensing at 30-100 km Altitudes 

Benjamin SchaferRarified Technologies, Inc. We propose a new approach to atmospheric sensing at 30-100 km altitudes using photophoretically levitating tracers. These lightweight structures harness sunlight to remain suspended for up to months at controlled altitudes and can be remotely tracked by satellite-based lidar or radar. Unlike natural aerosols, these tracers are designed to provide strong and […]

Actively Steerable Femtosat Constellations for In-situ Exploration of Saturn’s Rings, Atmosphere, and Magnetosphere
Actively Steerable Femtosat Constellations for In-situ Exploration of Saturn’s Rings, Atmosphere, and Magnetosphere

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
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
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
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%, […]

NASA, GE Aerospace Work Enables Hybrid-Electric Flight Demonstration
NASA, GE Aerospace Work Enables Hybrid-Electric Flight Demonstration

An aircraft powered by a megawatt-class hybrid-electric engine developed in collaboration with NASA and built by GE Aerospace, demonstrated flight of an innovation that can inform new generations of fuel-saving aircraft power systems. Mounted to a Saab 340B aircraft, the engine flew at Farnborough International Air Show in the United Kingdom. It was the public […]
