First In-FEEP Thruster Demonstration On-Orbit

In Jan 2018, Planet launched a technology demonstration of a 1U indium FEEP thruster module designed and built by Enpulsion. The thruster was integrated into a modified Planet 3U "Dove" satellite and launched on a PSLV.

Atmospheric Drag on LEO Spacecraft

Spacecraft lifetime in LEO is highly dependent on the atmospheric drag force and it's removal of energy from the satellite's orbit. Understanding the impact of drag on a design is important for early propulsion sizing estimates for spacecraft operating in the very low earth orbit (VLEO) range of 250-450 km.
