United Launch Alliance is concentrating on September 16 for the second take a look at flight of the brand new Vulcan rocket, and a flawless mission may lastly set the stage for the primary Vulcan launch for the US army by the tip of the 12 months.

The US House Power has contracted ULA’s Vulcan rocket to launch nearly all of the army’s house missions over the subsequent few years. Pentagon officers are anticipating Vulcan to get flying to allow them to begin checking off a backlog of 25 army house missions the House Power desires to launch by the tip of 2027.

By any measure, the primary Vulcan launch in January was a convincing success. On its debut flight, the brand new rocket delivered a industrial lunar lander to an on-target orbit. The subsequent Vulcan mission, which ULA calls Cert-2, would be the rocket’s second certification flight. The House Power requires ULA to finish two profitable flights of the Vulcan rocket earlier than entrusting it to launch nationwide safety satellites.

When the rubber hits the street

The stress on ULA to finish the second Vulcan take a look at flight was sturdy sufficient for the longtime army launch supplier, a 50-50 three way partnership between Boeing and Lockheed Martin, to announce final month that it’ll launch the subsequent Vulcan rocket with no actual payload. The spacecraft ULA wished to launch on the Cert-2 mission was the industrial Dream Chaser spaceplane developed by Sierra House. However Dream Chaser will not be able to launch in September and will not fly till subsequent 12 months.

As an alternative of incomes income on the Cert-2 mission, ULA will fly a dummy payload, or a mass simulator, contained in the nostril cone of the subsequent Vulcan rocket. Tory Bruno, ULA’s CEO, known as the corporate’s determination “certification at our personal expense.”

Two sources informed Ars that ULA plans to launch the second Vulcan rocket on September 16 from Cape Canaveral House Power Station, Florida. However for the reason that launch date is sort of two months out, do not be stunned if there are some minor changes to the schedule.

In June, ULA delivered the second Vulcan rocket to Cape Canaveral from its manufacturing unit in Alabama to bear ultimate processing earlier than stacking it on a cellular launch platform subsequent month. One factor that should occur earlier than then is the subsequent launch of ULA’s present workhorse rocket, the Atlas V, slated for July 30.

The Atlas V is absolutely stacked inside ULA’s Vertical Integration Facility at Cape Canaveral and can roll out of the hangar to the launch pad a few days earlier than liftoff. That is one in every of 16 Atlas V rockets left in ULA’s stock. Bruno mentioned ULA is on monitor to complete manufacturing the remaining Atlas V rockets by the tip of this 12 months, permitting the corporate to transform flooring house in its rocket manufacturing unit to ramp up manufacturing of Vulcan launch automobiles.

As soon as the Atlas V is off the bottom later this month, the hangar shall be clear to permit ULA to start assembling items of the second Vulcan rocket. Floor groups plan to conduct a countdown rehearsal in August, throughout which the launch staff will load liquid methane, liquid hydrogen, and liquid oxygen propellants into the Vulcan rocket.

For subsequent Vulcan flights, ULA will not have to carry out the countdown rehearsal, Bruno informed reporters final month.

Many of the remaining Atlas V rockets are assigned to missions for Amazon’s Mission Kuiper broadband constellation and astronaut missions on Boeing’s Starliner spacecraft. The Atlas V flight scheduled for July 30 would be the final Atlas V to launch a mission for the US House Power. It would even be ULA’s a centesimal nationwide safety mission total for the reason that firm’s founding in 2006 with the merger of the legacy launch companies of Boeing and Lockheed Martin.

US army and intelligence businesses have been the first clients for ULA, which operated the Delta IV and Atlas V rockets till the Delta IV’s retirement earlier this 12 months.

If all goes based on plan, ULA might be ready to launch its a hundred and first nationwide safety mission by the tip of the 12 months utilizing a Vulcan rocket. This mission, designated USSF-106, will launch an experimental demonstration satellite tv for pc right into a near-geosynchronous orbit for the Air Power Analysis Laboratory to check next-generation satellite tv for pc navigation applied sciences.
