The Los Alamos National Laboratory (LANL) has been awarded a highly respected 2026 R&D 100 Award, in the Process/Prototyping category, for development of the Autonomous Ion Mass Spectrometer Sentry (AIMSS). Referred to as the “Oscars of Invention,” the R&D 100 Awards honor the 100 most technologically significant innovations introduced globally each year, judged by an independent panel of industry experts from around the world.
Featuring a simple, robust design, AIMSS is a next-generation ion mass spectrometer designed to make critical ion mass composition observations in low Earth orbit. The instrument distinguishes between natural space plasma phenomena and spacecraft-generated contamination through precise ion species identification—a capability critical to Heliophysics scientific discovery and astronaut safety.
HTIDeS Technology Infusion and Rapid Development
This successful, award-winning development of the AIMSS payload is a direct technology infusion of the Compact Ion Mass Spectrometer (CIMS). CIMS (20-HTIDS20-0012) was developed under the leadership of Principal Investigator Carlos Maldonado (LANL) through strategic funding and technology maturation provided by NASA HESTO’s Heliophysics Technology and Instrument Development for Science (H-TIDeS) program.
By leveraging the foundational CIMS technology matured under HESTO, LANL executed one of its fastest payload development efforts since the Vela satellite era in the 1950s. The team successfully transitioned the H-TIDeS technology into an internal LANL research and development payload, accomplishing a complete design, build, and delivery of the AIMSS hardware in a record-breaking 22 months from project kickoff.
Mission Infusion: Launch and “First Light” Operations
Demonstrating a seamless transition from technology development to orbital operations, the AIMSS instrument was successfully launched on May 15, 2026, aboard SpaceX’s 34th Commercial Resupply Services mission. It is now flying as part of a Department of War Space Test Program Houston-11 payload on the International Space Station (ISS).
Following deployment, early on-orbit testing and commissioning confirmed successful ‘first light’ demonstration, with AIMSS capturing pristine oxygen ion distributions. After optimizing the electronics threshold settings, the team configured the payload for science operations. AIMSS is now actively monitoring ionospheric space plasma and measuring thruster plume contamination to protect the ISS from surface charging and electronic failures.
Ultimately, the R&D 100 Award, combined with successful ‘first light’ orbital operations, serves as a demonstration of how HESTO/H-TIDeS investments directly accelerate time to science and transition transformative space technologies from the laboratory to the launchpad.
