Magnetic topology and plasma diagnostics
A proposed first study would compare a small set of magnetic-nozzle geometries using direct thrust, electrical power, mass flow and plume measurements. Relevant expertise includes plasma diagnostics, RF engineering and electromagnetic modeling. The deliverable is a documented comparison and its limitations, not a preselected winning geometry. A negative result that removes an expensive design path is useful.
Microfabrication and emitter reliability
For electrospray concepts, investigate how reproducible geometry, liquid supply and extractor alignment influence emission stability and lifetime. A credible contribution defines the test population and failure criteria before selecting the best device. Manufacturing yield and variation matter alongside the performance of one sample. Any material or fabrication suggestion needs compatibility and contamination review before incorporation into an experimental plan.
Metrology and independent analysis
Force measurement, thermal characterization and uncertainty analysis are cross-cutting opportunities. A proposed analyst role would reproduce a result from raw data, challenge exclusions and test alternative explanations. A measurement role would improve a known limitation in the apparatus. These are scoped research needs, not announcements of hired staff, available facilities or existing partnerships.
Mission and systems integration
We welcome studies that translate component performance into a complete subsystem budget: source, converters, propellant, controls, cooling and structure. The comparison should use an explicit mission and a credible alternative. Researchers can contribute by identifying a requirement that makes a promising laboratory idea impractical, or by finding a narrower application where it becomes valuable. The ARLO and Moon concepts may inform future questions but are not committed customers.
A responsible first conversation
Send a nonconfidential summary of the question, relevant experience, primary references and proposed deliverable through the contact route. Before collaborative work begins, record background materials, contributors, data responsibilities and intended publication. Invention disclosures and rights questions should be addressed early with qualified counsel; this page makes no claim that a research direction is patentable or owned by Metric Flight. Public citations credit their authors and do not imply institutional endorsement.
What to include in a proposed study
A useful short brief names the comparator, measurement method, deliverable, required resources and the result that would end the study. Identify dependencies on specialist equipment or outside services explicitly. Metric Flight’s preference is an owned experimental capability; a proposal should not quietly assume borrowed instruments or laboratory access. Costs and schedules require a scoped design and quotations before they become commitments.
