This work introduces a novel passive ranging sensor based on metasurface optics (meta-optics), designed to reduce power and size requirements while enhancing RPO activities by utilizing a single aperture imaging and ranging sensor. The meta-optic device features subwavelength-engineered structures that encode range information using a rotational, double helix point spread function. This new sensor offers potential for reduced power …

Vision-Based Dynamic Tasking For Earth-Observing Satellite Constellations, Shreeyam Kacker, Kerri Cahoy, Kiruthika Devaraj, Işıl Demir, Steve Chien

Small Satellite Conference

Unpredictable phenomena such as cloud coverage pose a challenge for conventional Earth observation. Long lead times can cause conditions to change between forecasting, scheduling, and image capture, leading to suboptimal observations. To combat this, dynamic tasking has been proposed as a mission concept, where perception and autonomy are moved onboard the spacecraft in order to quickly respond to changes in the spacecraft’s imaging schedule, leveraging the compute power available in modern Earth-observing spacecraft. In this work, we explore the use of a wide field-of-view body-fixed lookahead sensor, separate from the main imaging payload, to evaluate the real-time utility of upcoming …

Teachers’ Challenges In Implementing The New Mexican School’S Educational Model, Mayra Margarito Gaspar

Journal of Educational Research and Practice

This scholarly essay explores the challenges that teachers face in implementing the Nueva Escuela Mexicana (NEM) [new Mexican school] educational model, which prioritizes project-based and interdisciplinary learning over subject-based instruction. The NEM’s flexible approach requires teachers to independently structure lessons, ensuring continuity without a predefined thematic sequence. Collaboration is essential, yet many educators struggle with interdisciplinary coordination, especially in secondary education. Limited planning time and curricular flexibility further complicate implementation. Teachers in marginalized areas also face resource constraints, which hinders project-based learning. Additionally, the NEM’s textbooks, which are designed for integrative learning, lack clear organization and guidelines and make them …

Lightsheet Anomaly Resolution And Debris Observation (Larado), Andrew Nicholas, Kenneth Marr, Josh Wolf, Charles Brown, Vanessa Kooi, Ted Finne, Scott Budzien, Cosimos Cendo, Ivan Galysh

Small Satellite Conference

Space objects in the size range of 0.1 mm to 3 cm are not currently trackable but have enough kinetic energy for lethal consequences to spacecraft. Small orbital debris poses a risk to most space missions; the detection of this debris requires a combination of a large sensor area and large time coverage. For example, a sensor with a time area product of 3 m²years can make a significant contribution to our understanding of the near-Earth small debris population. Deploying large sensors like physical witness plates is resource intensive, due to their size and weight. The light sheet …
