ELECTROADHESIVE ATTACHMENT FOR ORBITAL SERVICING
This paper presents validated electroadhesive attachment technology enabling diverse on-orbit servicing missions from active debris removal to scientific asset preservation. Testing demonstrates capture and control of rapidly rotating spacecraft exceeding traditional mechanical grappling limitations, expanding the addressable population of serviceable orbital objects. The research goal was validating universal attachment capability across mission types without requiring…

Resilient IP Distribution Techniques for SmallSat and Hybrid Space–Ground Architectures
SmallSat missions frequently rely on space–ground communication paths that are intermittent, asymmetric, or intentionally unidirectional. Compared to traditional GEO systems, SmallSats operate with lower transmit power, smaller antennas, and shorter contact windows, resulting in lower signal-to-noise ratios, burst packet loss, and constrained or unavailable return channels. These conditions are common in missions supporting SAR and…

OLAF: a Swarm of Microsatellites for Active Debris Removal by Space-based Laser Ablation
Small debris objects (1 mm–10 cm) pose a considerable risk to active spacecraft, potentially causing mission-critical damage as they can reach relative impact velocities of 15 km/s in LEO. ESA’s latest Space Environment Report estimates more than 130 million objects in this size range residing in LEO, the majority of which cannot be tracked by…

INTERNET PROTOCOL ROUTING IN CIS-LUNAR SPACE
Over the last five years, integrating space systems into the global Internet paradigm has advanced significantly. Space constellations and networks are now commonplace; however, current implementations remain limited to networks managed as single terrestrially orchestrated systems or orchestrated hybrid mixtures of interacting space networks. This centralized orchestration approach constrains autonomous operations, requires continuous ground station…

Enabling Software-Defined Satellites with Edge AI
Software-Defined Satellites (SDSs) enable spacecraft to evolve on orbit through software, moving beyond fixed-function architectures toward adaptable, multi-mission platforms. Software-defined radios and reconfigurable sensors and onboard compute systems provide foundational flexibility, while the integration of artificial intelligence at the edge is critical to achieving true operational autonomy. This presentation examines how AI-enabled onboard processing allows…

Ensuring Orbital Safety from T-0: The Critical Imperative for Immediate Post-Launch Collision Avoidance
As the density of the Low Earth Orbit (LEO) environment increases, driven by frequent rideshare missions and the deployment of mega-constellations, the initial phase of satellite operations has emerged as a period of heightened orbital risk. Historically, collision avoidance (COLA) processes have relied on established tracking by Space Situational Awareness (SSA) providers. However, this study…

MediSat: A Secure Delay-Tolerant CubeSat Constellation for Medical Data Relay in Infrastructure-Degraded Environments
Reliable transmission of medical data during disasters and in remote regions remains a critical challenge due to damaged, congested, or nonexistent terrestrial communication infrastructure. This paper presents MediSat, a SmallSat-based system concept for secure, delay-tolerant relay of medical data using a constellation of CubeSats operating in low Earth orbit. The proposed architecture employs a store-and-forward…
