Phase Four

Phase Four just completed performance testing of its Valkyrie Hall effect thruster at Georgia Institute of Technology's High Power Electric Propulsion Laboratory. HPEPL's VTF-2 vacuum chamber, with 350 kL/s of xenon pumping capacity is one of the highest fidelity test environments for electric propulsion systems. Here the Phase Four-built thruster produced 34.3 mN of thrust, 1,424 s anode specific impulse, and 50.6% anode efficiency at 475 W of discharge power on xenon. This is a key milestone test in the qualification of the Valkyrie Propulsion System, which is collaboratively produced by Phase Four and Redwire Space, with heritage technologies from both companies and commercially licensed designs from NASA Glenn Research Center. Thanks to Mitchell Walker, Dan Lev, William Brabston, and Ajay Krishnan for their support in the test, and congrats to Susan Jasmin Ossareh, Hamza Malik and the rest of team who continues to pull long weeks and nights to bring Valkyrie to commercial fruition!

This article encapsulates why Phase Four exists--we must change the way we move in space. As any military professional will tell you, the side that has advantage in maneuver typically wins. And as right now, the US is losing it's advantage at maneuver in space. In addition to selling propulsion systems for today's needs, Phase Four is developing and testing advanced propulsion systems on different fuels that will bring back our advantage in maneuver. We are at the bleeding edge of changing the way we move in space. #space #satellite #SDA #propulsion #nationalsecurity #AFRL #HET #multimode #China #spacesuperiority #SpaceRCO #SpaceSafari #LEO #VLEO #cislunar https://lnkd.in/ehUQCm3R

Proud to share that Phase Four has been selected for another SpaceWERX TACFI award! Our engineering team has been hard at work developing propulsion solutions for dynamic space operations capabilities, and this is great validation of our approach. Looking forward to delivering space flight hardware in short order!

Phase Four hosted nearly 100 visitors this week for it's annual Tech Day. Keynoted by LTG Phil Garrant, Commander, Space Systems Command, with former NASA Administrator Jim Bridenstine and the Defense Innovation Unit's Military Deputy, Steve Butow also addressing the crowd, it was quite the event. We were delighted to host several senior executives from satellite manufacturers; our panel featuring CEOs and CTOs of pioneering space companies discussing their propulsion needs was exceptional. The highlight of the day was seeing our Valkyrie fire, plus watching our 2-stage Wraith thruster in action--nothing like seeing and comparing different plasma plumes from different types of electric thrusters to get a bunch of space enthusiasts excited! #space #satellites #LEO #SDA #propulsion #PhaseFour #innovation #Valkyrie

Electric propulsion isn’t just about hardware. It’s about getting a fully tested system filled with propellant, tested for leaks, safely attached to a satellite and then mounted inside a rocket faring. Phase Four is an end-to-end electric propulsion company. Here is our team shipping our mobile fill-ops equipment to Vandenberg Space Force Base to do local propellant handling and filling at the launch site. We’ve performed such payload processing in Mahia, New Zealand, Cape Canaveral, Florida and Wallops Flight Facility, Virginia. Regardless of who you bought your electric propulsion from, we can service it, fill it, and/or safely ship it. #space #USSF #USSPACECOM #VSFB #propulsion #SDA #SpaceRCO #SpaceSafari #SSC #LEO

Looking for highly-reliable electric propulsion for your LEO, MEO or HEO orbits? Thinking of mono-propellant multi-mode propulsion? Have plans for VLEO? Need to service your electric propulsion before launch? Then you need Phase Four! Come and find our us at SmallSat next week. Steve Kiser and Jason Wallace will be there to discussion our broad in-space propulsion solutions. #SmallSat #Valkyrie #VLEO #PWSA #SDA #LEO #EP #MultiMode #PhaseFour

Space Development Agency Upsilon draft RFP is out--and if there was a mission that was tailor-made for the Valkyrie Hall Effect Thruster, this is it. With the highest thrust efficiency in its class, and designed for total impulse exceeding 1 MNs, this more than covers all the propulsion requirements SDA is asking for. Additionally, Valkyrie is designed to use krypton and xenon at a variety of set points, providing satellite OEMs unprecedented flexibility. If you're looking for a US supplier that can reliably deliver electric propulsion within 10 months, contact us today--we're here to support! #Valkyrie #SDA #Upsilon #propulsion #USSF #satellite #HET #HallEffectThruster #SpaceRCO #SpaceSafari #PWSA https://lnkd.in/eF67Ts84

The Valkyrie propulsion system continues to show why it is the best-in-class Hall Effect Thruster. The Phase Four and Redwire Space teams took the Valkyrie through its paces over the past two weeks on both xenon and krypton propellant, at set points ranging from 400-600 watts. This gives satellite builders great flexibility on electric propulsion architectures. The Valkyrie is the perfect solution for a wide range of missions profiles, including proliferated low earth orbit and agile geosynchronous missions. And best yet, we can reliably deliver in 10 months. #SDA #satellite #propulsion #space #LEO #GEO #newspace #plasma #HET

And it's time to scale. With this recent injection of capital, we're on our way to manufacturing and delivering up to 250 x Valkyrie Hall Effect Thrusters a year. With humanity planning to put nearly 60,000 satellites in orbit over the next 5 years, in-space propulsion will be a pinchpoint--and we're stepping into the breach. If you're launching into LEO or MEO and want a highly-reliable propulsion system from a highly-reliable team with high customer touch, we're here to help! #SDA #USSF #LEO #MEO #satellite #HET #propulsion #PLEO #USSPACECOM #SDA #investment https://lnkd.in/ePYWA9Pu
