Smallsat propulsion is undergoing a revolution

New Space startups are bringing innovative in-space propulsion systems to a satellite market that’s being rapidly redefined by small satellites. Advancements in propulsion systems have given rise to a fresh class of thrusters that are smaller, more efficient, cost less and are easily scalable. “What we’re seeing right now is a reasonably large disruption in the propulsion community and in the satellite industry,” said Dr. Alex Reissner, founder and CEO

Phase Four simplifies electric propulsion for mass manufacturing

In-space propulsion systems are getting a reboot. Spacecraft propulsion company Phase Four has built an electric radio frequency (RF) propulsion thruster that is easy to mass manufacture and doesn’t erode over time. The company recently announced a deal with small sat manufacturer Astro Digital, which will be using Phase Four thrusters on its Landmapper and Corvus satellites. Astro Digital will also act as a reseller for Phase Four propulsion on some
