United Launch Alliance continues to make strides in the direction of launching its first nationwide safety mission with its Vulcan rocket, however the actual timing of that launch stays unsure.
The U.S. House Drive’s House Methods Command remains to be within the technique of certifying the rocket following its second check mission (Cert-2), which launched on Oct. 4 with an inert payload. As soon as that’s full, it’ll pave the best way for Vulcan’s first flight below the Nationwide Safety House Launch (NSSL) program: USSF-106.
In a press release to Spaceflight Now on Oct. 24, Col. Doug Pentecost, SSC’s Deputy Program Government Officer for Assured Entry to House (AATS) mentioned the House Drive remains to be working by its evaluation of the Cert-2 mission.
“The launch date for USSF-106 remains to be being decided, pending decision of points from the Cert-2 launch, and completion of the certification course of,” Pentecost mentioned. “Remaining approval to launch any NSSL mission features a course of to resolve information observations and information anomalies of the earlier mission.”
In the course of the first minute of the Cert-2 launch, the nozzle of one of many Northrop Grumman-built GEM 63XL strong rocket boosters broke away. That brought about the Vulcan rocket to compensate for the scale back thrust.
Following the launch, Bruno mentioned that the impression of the misplaced nozzle was “lower than two % of the entire impulse” of the booster. He additionally acknowledged that the mission noticed an correct orbital insertion of the Centaur 5 higher stage.
Concerning how the nozzle anomaly could impression the work to certify Vulcan for NSSL missions, Pentecost mentioned that whereas SSC has its personal investigation underway, that doesn’t must be fully wrapped up with a view to end certifying the rocket.
“Inside our certification course of, we’ve the pliability to certify with open work so long as we’re glad that we’re on a superb path to decision, or wait till we’re fully glad the problems are resolved earlier than we certify,” Pentecost defined. “We’ve kicked off an investigation into the SRB anomaly to grasp root trigger and corrective motion.”
As of October 22, a ULA spokesperson mentioned its investigation was additionally nonetheless ongoing.
That mentioned, the certification of Vulcan might not be too far off now. Pentecost mentioned they’re primarily within the endgame of their work.
“We’re within the remaining section of the certification course of, reviewing information from the ultimate qualification check campaigns on Vulcan to solidify the technical baseline, and evaluating Cert-2 information to evaluation and modeling predictions,” Pentecost mentioned. “The ultimate approval for launch and certification of the baseline design are two separate processes.”
ULA’s first two missions for Vulcan following its certification are USSF-106 and USSF-87. The previous will launch the Navigation Know-how Satellite tv for pc-3 (NTS-3) and one other undisclosed payload for the U.S. House Drive.
USSF-87 in the meantime will ship a pair of satellites for the Geosynchronous House Situational Consciousness Program to Geosynchronous Earth Orbit (GEO).
Because it’s ready for approval to proceed with USSF-106, ULA stacked each the Vulcan booster and the Centaur 5 higher stage contained in the Vertical Integration Facility at Cape Canaveral House Drive Station.
The corporate additionally held a keel laying ceremony for the longer term R/S SpaceShip, the vessel that may assist transport future Vulcan rockets from ULA’s manufacturing amenities in Decatur, Alabama, to Florida. The ship is predicted to come back into service in early 2026.
