SPACE AND AERIAL VEHICLES

Deterministic Predictive State (DPS)

This architecture addresses speed-of-light delays (up to 20 minutes round-trip) on Earth-to-Mars and deep-space links. Instead of conventional transactional databases that lock under high latency, identical deterministic simulators run on both the ground segment and the remote asset. State consistency is maintained through fixed-point arithmetic and synchronized PRNG seeds referenced to a common clock. The ground side continuously generates a predictive state of the remote system. When actual execution logs arrive via Delay-Tolerant Networking, a bounded delta correction is applied using Conflict-Free Replicated Data Types. The method is restricted to algorithmic, fully predictable workloads such as trajectory propagation, telemetry processing, and resource scheduling.

Path-Diverse Optical Mesh with Erasure Coding (PDOMEC)

A link-layer approach for optical inter-satellite links that experience packet loss from angular jitter, debris, or thruster firings. Rather than relying on ARQ retransmissions, the system applies RaptorQ fountain codes to the payload and distributes the encoded blocks across multiple non-intersecting paths in the constellation mesh. The receiver reconstructs the original data as soon as any sufficient subset of blocks arrives, independent of individual path delays caused by orbital geometry. The method is designed to operate on existing Starlink-class laser terminals without hardware changes.

Eclipse-Phase Passive Preprocessing with Graphene Thermal Structures (EPP-GTS)

A thermal and power management method for LEO sensor satellites that perform onboard data processing. High-rate sensor processing, feature extraction, and compression are deferred to the eclipse portion of the orbit, when background temperatures are lower. During eclipse the compute cluster draws power from a dedicated LFP battery sized for deep-cycle operation. Waste heat is rejected passively through high-emissivity graphene-enhanced deployable radiators. Only the reduced-volume processed data is downlinked on subsequent sunlit passes, thereby limiting peak thermal and power loads on the spacecraft bus.

In Situ Eutectic Ultra-High Temperature Ceramic Coatings (ISE-UHTC)

An ultra-high temperature ceramic coating for reusable launch-vehicle leading edges and hypersonic surfaces operating above 2000 °C. Conventional powder blending creates weak interfaces that crack under thermal cycling. In this process, dirhenium (Re2) cluster units are covalently incorporated into boron- and silicon-containing preceramic polymers and sol-gel precursors. During controlled pyrolysis the molecular Re2 fragments convert into finely dispersed eutectic phases that locate preferentially along ZrB2 or HfB2 grain boundaries. Under oxidative thermal stress a limited silicide-borate glass forms and is drawn by capillary action into micro-cracks, slowing further oxygen penetration. Because the rhenium remains chemically bound until the ceramic network begins to densify, agglomeration is reduced compared with simple powder addition. The liquid or gel precursors are compatible with standard dip, spray, or spin coating. Early cyclic testing demonstrates measurable gains in crack resistance, with long-term oxidation kinetics and rhenium cost-efficiency profiles undergoing active validation.

Cluster-Stabilized Topological Graphene Aerogels (CST-GA)

An ultra-low-density graphene aerogel intended for cryogenic propellant-tank insulation and deep-space thermal management. Standard carbon aerogels lose structural integrity under vibration and accumulate radiation damage. The graphene network is cross-linked during gelation and carbonization with rigid dirhenium (Re2) cluster nodes that bind to defect sites, forming localized metal-carbon bonds. These nodes resist sintering, stabilize pore walls, and provide distributed high-Z attenuation of secondary radiation without significant mass penalty. Pore structure is controlled by conventional process variables (concentration, solvent exchange, freeze-drying). Laboratory samples retain low density while exhibiting improved compressive recovery and vibration tolerance. Current operations are scaled for custom batch fabrication, with long-term vacuum and radiation stability parameters undergoing active qualification under representative mission profiles.
