CURATOR ABSTRACT & SYNTHESIS

Engineers at Marshall Space Flight Center achieved over 251 seconds of continuous burn on a full-scale RDRE using copper-alloy additive manufacturing. Pressure-gain combustion provides a 15% leap in specific impulse over conventional chemical cycles.

Observatory Field Notes:

Substantial leap in compact upper-stage efficiency.
