Mission brief

The flight at a glance.

Replacement Vulcan test launch with inert payload, experiments, and demonstrations for certification with the USSF after delays caused by payload testing of the Sierra Space Dreamchaser CRS SNC-1 mission, the original planned payload. One of the GEM-63XL SRBs was observed to blown out its booster nozzle at T+37 seconds, causing reduced and asymmetric thrust during ascent, however the performance shortfall was fully compensated by Vulcan's other stages.
