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.

Recently, the technical objectives of ITER were redefined aiming at a cost reduction of ~50% from the 1998 ITER design. Machine parameters that would satisfy the revised technical requirements under the engineering constraints were specified using a system code. The performances of the 1998 ITER and a redefined machine were studied and compared. As a result of these studies, final machine parameters were determined with revised conservative physics assumptions. This redefined machine is referred to as ITER-FEAT. It was shown that ITER-FEAT would achieve Q = 10 in inductive operation with reasonable and conservative assumptions. Also, with an efficient current drive system and modest confinement improvement, the possibility of Q = 5 noninductive operations in a steady state was shown.
