01

Hermetic GN2 Overpressure

Highway transit subjects containers to varying atmospheric pressure as elevation changes. Maintaining a steady positive differential pressure (+0.10 to +0.25 psi) ensures that ambient highway fumes, salt spray, and moisture cannot breach container seals into sensitive spacecraft optics.

02

Tuned Wire-Rope Damping (<0.5G)

Solar arrays, feed horns, and traveling-wave tube amplifiers (TWTAs) are vulnerable to highway micro-vibration. Specialized trailers combine air-ride suspensions with tuned stainless-steel helical wire-rope isolators inside the transport frame, dampening resonance between 3Hz and 200Hz.

03

Spaceport Airside Handoff

Delivery to facilities like Astrotech Space Operations (Titusville) or KSC Multi-Payload Processing Facility (MPPF) requires continuous airlock protocol. The transport convoy integrates airside airport transfers (C-17 / Antonov An-124) directly to dedicated air-ride climate-controlled carriers.
