Space Environment Technologies — ARMAS

Radiation monitoring from stratosphere to lunar surface. FO balloon testing matured ARMAS to TRL 9, enabling FM11 to land on the Moon aboard IM-2 Athena, March 2025.


Summary

Space Environment Technologies (SET), Pacific Palisades CA, developed the Automated Radiation Measurements for Aerospace Safety (ARMAS) system over 15+ years through an extensive NASA FO + SBIR maturation chain. FO project 106715 was the final pre-operational balloon demonstration (2020–2024, TRL 7→8/9). In 2025, ARMAS FM11 flew on Intuitive Machines IM-2 Athena and landed on the Moon — the second documented FO → lunar mission infusion after NDL/Psionic → IM-1. SET also commercialized ARMAS for Virgin Galactic's Delta fleet, commercial aviation flights, and a Navy subscription data service.

FO Project Chain

Project Period Vehicle TRL Gain Key Result
ARMAS predecessors (1–6) 2011–2016 Various balloons Incremental Validated TRL progression from laboratory to stratosphere
89360 ARMAS-Hi 2017-04–2019-02 Commercial aircraft + balloon 6→7 First real-time COTS-based global operational radiation dose assessment at high altitude; direct application to space tourism safety and commercial aviation. PI: W. Kent Tobiska.
106715 ARMAS DM POMD 2020–2024 World View balloons (28-day) + Blue Origin New Shepard (2022) 7→8 (project) / 9 (SET claim) 28-day continuous aviation radiation monitoring; suborbital deep-space environment prep

The project title: "ARMAS Dual Monitor Pre-Operations Mission Demonstration (ARMAS DM POMD)" — dual detector array measuring: total ionizing dose, gamma rays, LET spectroscopy, and tissue equivalent proportional counter (TEPC).

Connection to World View Enterprises: The balloon tests used World View's stratospheric balloon platform — the same company whose altitude control system was validated by FO project 89368. Two FO projects in the KB share infrastructure.


Lunar Mission: ARMAS FM11 on IM-2 Athena

Item Detail
Vehicle Intuitive Machines IM-2 Nova-C "Athena" lunar lander
Launch February 26, 2025
Landing March 6, 2025 ~17:35 UT
Landing site Mons Mouton region, lunar south pole (250m from target, inside crater)
Distinction Southernmost lunar landing and surface operations ever achieved
Outcome Lander tipped onto its side → early termination. ARMAS FM11 functioned throughout transit.
Data collected ~32 hours of radiation measurements from GEO through deep space, Van Allen belts, lunar orbit, landing, lunar surface
Host payload Part of Lonestar Data Holdings (St. Petersburg FL) "Freedom" payload on IM-2

Data value: First-ever continuous radiation measurement across six distinct regions (Earth upper atmosphere, Van Allen belts, deep space, lunar orbit, lunar landing, lunar south pole surface). Data currently being analyzed to inform next-generation landers and crewed missions.

NASA confirmation: The FO program's transitions page is titled "Flight-Tested Technologies for Safety in Space Head to the Moon" and explicitly describes the FO balloon tests as the maturation path enabling the lunar mission.

Outcome Chain

Lab development (SET, Pacific Palisades) 
  → NASA SBIR Phase I/II chain (2005–2019)
  → FO balloon tests with World View (multiple, 2011–2024) [Project 106715]
  → FO New Shepard test (2022) — sub-orbital preparation
  → FO TRL 7→8/9 achieved
  → ARMAS FM11 commercial flight on Virgin Galactic Delta fleet
  → ARMAS FM11 on IM-2 Athena → lunar south pole, March 6, 2025
  → 32 hours deep-space radiation data collected (first-ever cross-region dataset)
  → Data feeds Artemis crewed mission radiation planning

Archetype: Long-running platform maturation via FO → dual commercial (Virgin Galactic, aviation) + government infusion (lunar CLPS) outcomes. SET is a classic small company whose technical roadmap was co-funded across 15+ years by FO + SBIR + DoD subscriptions.
