The Reliability Backbone
of Micropropulsion
We build the electronics and test infrastructure every electrospray team needs today — and use them to build the self-healing thruster of tomorrow.

The Electrospray
Lab in a Box
Bipolar ±0.5–6 kV. Programmable polarity alternation.Flipping the voltage polarity on a schedule. Without it the propellant slowly destroys the emitter through electrochemistry — it is the single cheapest way to extend thruster life. Floating HV-side sensing at 1 nA. Neutralizer channelA thruster shooting out ions would charge the satellite until it stops working. The neutralizer sprays electrons back out to keep it electrically balanced., arc countingCounting micro-sparks. A rising arc rate is the earliest warning that a thruster is starting to fail., Python API. One box instead of the $40–80k improvised bench — for $18–35k.

1,000-Hour Wall
Qualification demands 1,000+ hour firings; Europe's verified record is 400 h. Our automated vacuum chambers run your thruster around the clock — your thruster, our chamber, your live data feed.

The Industry's
Health Record
Every bench and every campaign feeds a cross-thruster library of degradation signatures — overspray onsetWhen a thruster starts spraying propellant onto its own extractor grid instead of out the back. It is the number-one killer of electrospray thrusters — and it is visible in the current trace long before it is fatal., clogging tracesThe microscopic channels that feed propellant to the emitters slowly block up. The flow signature changes in a way you can measure., arc clusteringSparks stop being random and start grouping together — a statistical tell that failure is approaching.. Hardware gets copied. A dataset only accumulates. Anomaly alerts and remaining-life estimates, as a subscription.

MycoThruster
A self-healing electrospray. Mycelium-inspired feed in independently-plumbed zones — per-zone telemetry throttles a degrading zone before it poisons the extractor, and the network reroutes around damage. The industry flies open-loop. We already sell the loop.
