ion (n.)

1834, introduced by English phycisist and chemist Michael Faraday (suggested by the Rev. William Whewell, English polymath), coined from the greek "ion", neuter present participle of ienai, "go," from the root "to go", so called because ions move toward the electrode of opposite charge.

ienai SPACE was founded with a mission to change the way the on-board electric propulsion market operates. We believe that clients should not be forced to build their spacecraft around a small number of available propulsion products, but that these systems should adapt to the constraints and requirements of each individual mission.


Our goal is to remove entry barriers for the adoption of electric propulsion technologies in the smallest of satellites, providing platform manufacturers and integrators with the tools necessary to understand their propulsion requirements, and the best possible hardware to address them.

Our Rockstar Team

Who said that space should be boring?

The founding team are doctoral graduates from the Electric Propulsion and Plasmas group at UC3M and were first recognized for their groundbreaking contribution at the 2017 35th International Electric Propulsion Conference. Since then, the team has grown to carry out the vision of concurrent design for propulsive missions and systems and the drive to bring a revolutionary new product to the space market.
