Direct Fusion Drive

<p>Direct Fusion Drive (DFD) is a conceptual, low <a href="/facts/Radioactive_decay/Ya6FVjt4">radioactivity</a>, nuclear-<a href="/facts/Fusion_rocket/HonbIews">fusion rocket engine</a>, designed to produce both <a href="/facts/Thrust/EM04CqV7">thrust</a> and electric power, suitable for <a href="/facts/Interplanetary_spaceflight/4HGDAA2g">interplanetary spacecraft</a>. The concept is based on the <a href="/facts/Princeton_field-reversed_configuration_experiment/Q8d3QVNS">Princeton field-reversed configuration reactor</a>, invented in 2002 by Samuel A. Cohen. It is being modeled and experimentally tested at <a href="/facts/Princeton_Plasma_Physics_Laboratory/YEBMkkow">Princeton Plasma Physics Laboratory</a>, a <a href="/facts/United_States_Department_of_Energy/PRp6Cz8g">U.S. Department of Energy</a> facility, as well as modeled and evaluated by Princeton Satellite Systems (PSS). As of 2018, a direct fusion drive project driven by NASA is said to have entered its simulation phase, presented as the second phase of the concept's evolution.
