Size

Traditional re-entry vehicles were designed for government-led missions, not the demands of modern commercial orbital logistics. Heat Shields with rigid aeroshells or mechanically deployed thermal protection systems impose fixed geometry, limited size & volume, constrained power capacity, and high structural mass. The result is low payload return capacity, high cost per kilogram and long mission timelines making the routine return of large payloads from orbit impractical, expensive, and infrequent.

Advanced Orbital Return Systems for Commercial Space Logistics

ReX is a next-generation orbital re-entry system designed to break the size constraints of legacy systems. Built around an origami-inspired, deployable thermal protection system (TPS), using commercially-off-the-shelf materials, ReX increases aerodynamic drag at much higher altitudes, slowing the system from hypersonic velocities (Mach 25+) earlier in the descent. This dramatically reduces thermal loads, lowers heat shield mass, and unlocks substantially greater payload return capacity. By replacing rigid, mass-intensive architectures with a lightweight deployable design, ReX enables routine, scalable, and cost-effective return from orbit.

HIGH PACKING DENSITY
Large diameter foldable TPS sits compact in stowed arrangement, reducing heatshield structural size.
ULTRA- LOW BALLISTIC COEFFICIENT
Greater surface area enables earlier deceleration, reducing peak heating and structural loads.
NO INFLATION PLUMBING
Proprietary deployment technology removes pressurized systems, reducing failure modes and integration complexity.
VERTICAL INTEGRATION
nd-to-end in-house assembly, integration, and testing ensures system-level control, faster iteration, and standardized performance across missions.

This results in increased survivability of sensitive payload types such as semiconductors, medications, and biocargo.
