About this launch
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.
