official news from : https://bit.ly/2QkyIbY 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 areContinue reading “Photophoretic tracers for near-space remote sensing at 30-100 km altitudes “

official news from : https://bit.ly/2QkyIbY Pablo SobronSETI Institute This proposal explores a new class of reconnaissance spacecraft that map minerals from orbit using Raman spectroscopy during high-speed flybys–without landing, sample return, or extended dwell. If feasible, this concept would enable NASA to evaluate ice and ilmenite at the Moon, ore content at asteroids, and volatile-bearing mineralsContinue reading “Interworld Slingshot Resource Surveys”

official news from : https://bit.ly/2QkyIbY David SmithDuke University  The increasing population of spacefaring vehicles and satellites motivates increasingly powerful technologies for space situational awareness (SSA). While the US space surveillance network (SSN) is able to monitor objects down to about four inches in size using, for example, the latest upgrade to the space fence, the associatedContinue reading “Robotically Assembled Electromagnetic Metamaterials for Long-Range Space Situational Awareness “

official news from : https://bit.ly/2QkyIbY Paul StankusBrookhaven Science Associates The scientific goal of the proposed work will be reconstructing the image, ie resolving surface features, of an Earth-like exoplanet around a nearby star as seen in visible light. The innovation is in two stages. First, the design of a new kind of nulling interferometer — “dynamicContinue reading “Mapping Alien Continents: Achieving Optical VLBI for Exoplanet Imaging “

Psyche flew by Mars on May 15, 2026, using the planet’s gravity to gain speed and slightly tilt its trajectory. The flyby also gave the team anContinue reading “Psyche Approaches Mars”

official news from : https://bit.ly/2QkyIbY Background Human exploration of Mars will expose crews to a persistent, fine particulate environment whose physicochemical properties and health implications remain only partly understood. Because no samples of authentic Martian airborne dust have been returned to Earth, NASA must rely on lunar dust toxicology, Martian regolith simulants, and extensive rover/landerContinue reading “Establishing Crew Exposure Limits of Martian Dust”

official news from : https://bit.ly/2QkyIbY A team of NASA-sponsored scientists and engineers has developed a novel approach to observing high-energy particles in the near-Earth space environment, incorporating miniaturized sensors into a compact, multi-view particle detection instrument unlike any before it. Built for NASA’s Relativistic Electron Atmospheric Loss (REAL) CubeSat mission, the innovative instrument (also calledContinue reading “A New Compact Instrument Enables High-Fidelity Measurements of Energetic Particles on CubeSats”
