PROPELLING THE FUTURE OF OUR PLANET
Phase Four is building a game-changing, high performance satellite propulsion system.
Plasma is the fourth phase of matter.
Using new applications of plasma-related technology, Phase Four will advance space missions through unprecedented innovation and cost effectiveness.
Phase Four's innovative thruster technology enables small satellites to have the capabilities of their larger, older siblings.
Even a basic capability to push in one direction would allow nanosats to remain in orbit longer, or allow a satellite that has been placed into low-Earth orbit, using an inexpensive launch provider, to nudge itself to a higher geostationary orbit. And some might travel far beyond Earth.

Propelled CubeSats could even be useful back here on Earth. Creating a universal "satellite Wi-Fi", like existing satellite phone coverage, would require thousands of big satellites, which is prohibitively expensive. But you could dump a thousand CubeSats in one place then spread them out to the right points, for a fraction of the price.
As NASA develops and improves the use of small satellites for science and exploration, we recognize propulsion as a critical need to open the door for small spacecraft applications. We need better miniaturized systems to propel and maneuver our small space adventurers.
