P4, What For?

Our first-ever episode aimed to answer the question "what is plasma?" Today, we go much deeper with Phase Four plasma physicist Derek Thompson as we tackle what "propellant agnosticism" means for the Phase Four RF thruster (RFT). Dr. Thompson examines what allows the RFT to be propellant agnostic, and what makes a good propellant.

Last week, we talked to Phase Four CEO Beau Jarvis about international sales partners, and how he thinks about growth and expansion for space companies. He focused on traditional sales partners, but brought up the concept of "strategic partners". Today, we're thrilled to be joined by VP operations Jason Wallace and director of supply chain Laura Overly, who help us define a strategic partnership--and the challenges and opportunities behind them.

2019 has been a big year for Phase Four. In addition to launching Maxwell, our turn-key propulsion system for small satellites, we announced a big commercial partnership with Sunrise, a Japan-based technology company helmed by Dr. Hiroshi Nashimoto. "If you look at dollars invested in commercial space, Japan is the second largest market--even larger than Europe. That was eye-opening. That's a market we wanted to get in, and get moving quickly, which is why we went to a partner," says Phase Four CEO Beau Jarvis. Today, we sit down with Beau to explore how he thinks about setting up an international sales network: Why set one up to begin with? How should you think about timing the expansion of your sales network? Subscribe to P4W4 on Spotify, Stitcher, Apple Podcasts, and Google Play.

A couple weeks ago, we shared a milestone with our followers on Twitter: our first "kit" for Maxwell, Phase Four's turn-key propulsion system for small satellites. Today, we sit down with Phase Four's director of supply chain Laura Overly to help clarify what kitting is, and why it's important.

Phase Four software lead Dillon Krasovec talks through the trend of “digitizing hardware”. Can you even find a toaster that doesn’t have at least eight buttons these days? Dillon dives into how that trend is affecting the aerospace industry, and what considerations lay behind Phase Four’s decision to digitize the RF thruster.
