Space propulsion developer Accion Systems has closed its most significant funding round yet. The company raised $42 million in a Series C led by Tracker Capital, bringing its valuation to $83.5 million.
Along with the investment, Tracker Capital also acquired a majority stake in the company. This latest injection of capital will facilitate the development and manufacturing of the company’s fourth generation propulsion system, dubbed the tiled ionic liquid electrospray (TILE) system.
The TILE system uses electrical energy to push charge particles (ions) out its back to generate propulsion. While ion engines have been around for decades, Accion uses a liquid propellant, an ionic liquid salt, instead of gas. The liquid is inert and non-pressurized, meaning there’s no risk of explosion. It also results in a product that doesn’t need bulky components like ionization chambers, and an overall smaller and lighter weight system relative to the spacecraft – key considerations in space, where every gram of payload has a high price tag.
“It lets us build really, really small systems,” Accion co-founder Natalya Bailey explained to TechCrunch. “Instead of trying to take an existing ion engine the size of a Prius and shrink it down, we can start with very small systems because …read more
