Axiom Space, Kepler Ready Orbital Computing for Quantum Era

ANTALYA, Türkiye — October 6, 2026 — Axiom Space today provided an update on its orbital compute strategy, highlighting progress on its Axiom Resilient Compute (ARC) platform, a step toward a distributed model for space-based workload orchestration, AI/ML processing, and post-quantum secure communications.

Axiom Space currently operates two ARCs on orbit, launched earlier this year as part of Kepler Communications' optical data relay satellite constellation and developed with granted funds from the Texas Space Commission. The company has confirmed ARC-to-ARC and ARC-to-ground communications and separately completed a ground demonstration in which a post-quantum cryptography (PQC) encrypted workload was successfully migrated, early proof of securing compute at the edge of the network, in space or on Earth.

"Satellite sensor and operations systems generate more data than communication systems can transmit to ground stations during an orbit," said Dr. Jonathan Cirtain, CEO and President of Axiom Space. "The capacity to generate space-based data will only increase, and the solution isn't just more bandwidth, it's less dependence on bandwidth in the first place, by securely processing data close to where it's captured. That's the problem ARC exists to solve."

The update comes as organizations across government and industry face a hard deadline: a June 2026 Executive Order and accompanying OMB guidance requiring U.S. agencies to migrate high-value assets and high-impact systems to post-quantum cryptography keys by the end of 2030, and to PQC digital signatures by the end of 2031. The mandate is intended to close the window on "harvest now, decrypt later" tactics, in which encrypted data is intercepted today for decryption once quantum computing matures.

Axiom Space's ARC platform is designed to bring secure communications and compute directly into orbit, giving operators a path to compliance and a hedge against future decryption risk, whether the data originates in space or needs to be processed and secured close to its terrestrial source. The PQC compliant encryption is integrated at the silicon level and in the software layer.

ARC 1 and ARC 2 fly as part of Kepler Communications' optical relay network. Since 2023, Axiom Space and Kepler have collaborated on integrating optical intersatellite links (OISLs) to enable high-speed connectivity between orbital compute assets and government or commercial spacecraft. This tranche incorporates 2.5 Gbps optical links compatible with the Space Development Agency's Tranche 1 optical communications standards, positioning the ARC network for interoperability with a broad range of commercial and government networks.

“Our customers need security now more than ever,” said Kepler Communications U.S. President, Caitlin Marsh. “On-orbit compute is a core capability of Kepler’s constellation, supporting customer workloads such as orchestration and AI/ML processing in space. This capability is already in orbit and works with Kepler’s optical data relay network to get customers the data they need, when they need it, while helping to futureproof their operations for a changing security landscape.”

Built for orbit, the ARC platform applies equally to terrestrial critical infrastructure operating under denied or intermittent connectivity. It brings sovereign, on-site edge AI compute and post-quantum data protection to remote operations such as oil and gas, mining, subsea, and maritime energy that must keep running in the most challenging and disconnected environments on earth.

Axiom Space's next milestone is an on-orbit demonstration of the ARC platform's post-quantum cryptography capability, building on the ground-based validation completed to date. Beyond that, the company plans to scale the ARC network from its current prototype infrastructure to a global, sovereign, PQC-capable orbital processing capability, giving customers a viable alternative to terrestrial compute and supporting what the company sees as the next era of space-enabled digital infrastructure.
