The Picaso Trial: Studying Aya Chronic Illness Self-Management Using A Noncategorical Approach, Sharron L. Docherty, Gary Maslow, Mclean Pollock, Susan Silva, Erin Denio, Lakaya Craig, Remi Misiewicz

International Nursing Research Congress (INRC)

Background: Adolescents and young adults (AYA) with childhood-onset chronic conditions often struggle during the transition from pediatric to adult healthcare and from being a child living with a chronic condition to an adult who effectively manages their chronic condition. Despite shared developmental, psychosocial, and healthcare transition challenges, most research is condition-specific, limiting generalizability and overlooking shared self-management needs (1-3). The PiCASO study evaluated a peer coaching intervention to improve self-management and patient activation among AYA during this critical transition and demonstrated the feasibility and impact of a noncategorical approach.

Methods: A randomized controlled trial was conducted in which 222 AYA …

Operational Resilience In Cubesat Tracking Operations Through Complementary Architectures At Dss-17, Andrea Togni, Emily Walter, Chloe Hart, Ryan Collins, Noah Patrick, Christo Smith, Nathan Fite, Benjamin Malphrus, Marc Sanchez-Net

Small Satellite Conference

Loss of phase-locked loop (PLL) lock during CubeSat tracking can simultaneously eliminate both telemetry and Doppler observables, leaving operators blind during critical mission phases. While closed-loop receivers provide high-precision tracking under nominal conditions, they remain vulnerable to low signal-to-noise ratio, rapid Doppler dynamics, oscillator instability, and modeling errors. This single-point failure mode reduces operator situational awareness precisely when it is most needed. This work presents a dual-acquisition architecture that eliminates single point failure in CubeSat ground tracking. Implemented at DSS-17, Morehead State University's 21-meter deep-space antenna, the system pairs a conventional closed-loop modem with a parallel open-loop receiver implemented on …

The Billion Dollar Surprise: How Solar Cycle 25 Cut Satellite Lifetimes In Leo, Scott Shambaugh

Small Satellite Conference

Solar Cycle 25 has run far stronger than the 2019 consensus forecast issued by the NOAA/NASA/ISES prediction panel, with densities in low Earth orbit from 2022-2026 holding at 2-3x the predicted levels. The cumulative drag impulse experienced by LEO satellites, which is the driving metric for propellant budgets and mission lifetimes, reached 5-6 standard deviations beyond the forecast’s stated uncertainty. This means that even operators who designed conservatively against the two-sigma worst case fell short of their drag budgets. This paper quantifies a lower bound on the economic cost of that misprediction.

Starting from the 13,704 payloads on-orbit below 800 …

Scaling Distributed Spacecraft Autonomy Operations With Simple Temporal Networks: Introducing Splinter, Michael Iatauro, Caleb Adams, Caroline Lassiter

Small Satellite Conference

The Absolute Time Sequence (ATS) is a well-established mechanism for high-level spacecraft control, executing commands at specific times. One weakness of ATSs is that the cost of making a change to the command sequence grows with the length of the sequence, and the cost paid is many repetitive-but-detailed changes to the timing of commands, which is error-prone.

This weakness becomes a liability when scaling up to spacecraft swarms or long ATS durations because any perturbation to the command sequence or schedule incurs significant cost. Fitting that cost within a small team or short sequence development timeline becomes a central challenge …

Energy-Aware Dynamic Tasking For Earth Observing Satellites With Deep Reinforcement Learning, Nicholas Nordlund, Tim Upthegrove, Leandros Tassiulas

Small Satellite Conference

Dynamic tasking for agile Earth-observing satellites (AEOS) adapts preplanned schedules using onboard lookahead sensors to detect cloud cover that obscures targets. Existing approaches decompose tasking into sequential lookahead, maneuver, and capture stages, limiting their ability to manage tradeoffs over long time horizons. Instead, we formulate dynamic tasking as a constrained partially observable Markov decision process (CPOMDP) and introduce Cloud-Aware Dynamic Earth-observation Tasking (CADET), a deep reinforcement learning (DRL) framework that jointly selects maneuvering and sensing actions under resource constraints. We derive a closed-form model for the probability that a target is visible given a spatially aggregated lookahead observation, …
