How TEC is accelerating Europe’s next propulsion systems on Sift

Propulsion development lives or dies by test cadence. When the data pipeline is fragmented , the iteration loop slows. The Exploration Company (TEC) tests with Sift, accelerating two of Europe’s most ambitious propulsion programs: the Mistral green hypergolic thruster and the Huracan electric-pump-fed cryogenic rocket engine.
