Proving DRACO will deliver
The United States is now closer than it has been in over five decades to launching the first nuclear thermal rocket into space, thanks to DRACO—the Demonstration Rocket for Agile Cislunar Orbit.

Estimates of the ARIES-I current and fusion-power rampup have been made using a profile-averaging, plasma/circuit simulation model. For the case of a combined inductive and rf-assisted startup, a minimization of non-inductive startup power needed to supply both resistive and inductive magnetic-flux requirements generally favors a low-density current rampup, which is then followed by a DT fueling schedule that brings the plasma to full fusion power.
