At the conclusion of our longest test campaign, totaling 2033 seconds of run time, E-2 demonstrated a rapid relight test fire.
This test consisted of a 212-second burn with a nominal shutdown, followed by an 8-second pause and a successful engine relight. This sequence simulates a first stage flight profile followed by the brief coast period that would occur between main engine cutoff and the burn required to return the stage for landing.
This milestone represents a key step toward demonstrating rapid reusability, marking a fitting conclusion to a remarkable test campaign. E-2 was designed for rapid reuse, which is an essential capability for the future of spaceflight. We will continue advancing and validating this capability in future testing.
