About Accion

Accelerating a Sustainable Future in Space

At Accion, we re-engineered propulsion for the needs of New Space. Like the bold missions we enable, we’re pushing the boundaries of what’s possible.

Our Mission

Our mission is to redefine the safety, efficiency, and scalability of spacecraft propulsion systems to expand what’s possible in space.

Tiled Ionic Liquid Electrospray (TILE) is a revolution for electric propulsion. TILE’s low power draw allows satellites to maneuver without turning off their other payloads, unlocking new possibilities. And as space grows more crowded, TILE enables satellites to operate sustainably by avoiding collisions and deorbiting without the risk of explosion.

Accion Leadership

Dr. Natalya Bailey and Louis Perna, veterans of NASA and MIT, founded Accion Systems after developing TILE at the MIT Space Propulsion Lab. Since 2014, the company has built a team brimming with technical and business leadership experience to help scale Accion’s state-of-the-art propulsion technology.

We are driven by innovation through collaboration. Whatever your vision for space is, we’re here to accelerate it.

“We want to make space more affordable and accessible by changing what spacecraft can do in and beyond Earth’s orbit.”

Our Story

Satellites can do extraordinary things. They can connect the world with global internet coverage. They can keep us safe by watching from above. They can support a sustainable future by helping us manage our resources.

But without propulsion, satellites are like ships at sea without a sail. Due to prohibitive costs and size, weight, and power (SWaP) constraints, satellites often launch without adequate propulsion. This limits mission lifetime, exposes spacecraft to collisions, and creates space debris.

To accelerate the potential of New Space, we created a high-performance propulsion solution that works for all spacecraft, from 1U cubesats on up. Ionic Liquid Electrospray is the most efficient known form of propulsion, fitting powerful thrust in a package small enough for small satellites, and scalable enough for the needs of constellations and larger spacecraft.
