United Launch Alliance (ULA) is preparing for the inaugural flight of its new Vulcan rocket from Space Launch Complex (SLC) 41 at the Cape Canaveral Space Force Station in Florida. Liftoff is currently scheduled for Jan. 8, 2024, at 2:18 AM EST (07:18 UTC).
Onboard this first flight will be Astrobotic's Peregrine lunar lander, part of NASA's Commercial Lunar Payload Services (CLPS) initiative and the Artemis program.
The Vulcan Centaur rocket stands 61.6 meters (202 feet) tall with a consistent diameter of 5.4 meters (18 feet). ULA offers two different-length payload fairings, including a 15.5-meter (51-foot) short fairing and a 21.3-meter (70-feet) long fairing.
The first stage booster of the vehicle is made of aluminum orthogrid tanks that hold over 450 tonnes of liquid oxygen and liquid natural gas, which is nearly pure liquid methane. This marks ULA's first methalox vehicle or a vehicle that uses liquid oxygen as an oxidizer and a form of methane, in this case natural gas, as fuel.
Each engine outputs 2.45 meganewtons (550,000 pounds) of thrust at sea level. Additional thrust is available with the use of GEM 63XL solid rocket boosters manufactured by Northrop Grumman Space Systems.
Vulcan is available with either zero, two, four or six SRBs (Solid Rocket Boosters). Vulcan's inaugural flight will feature two mounted SRBs. The GEM-63XL boosters are constructed out of a graphite-epoxy composite with the throttle profile pre-formed into the propellant grain.
NASA is heavily invested in Peregrine Mission One as it seeks to reboot human moon exploration by its Artemis program. The right technical risk level, financial filters and other factors have been challenging in NASA's formulation of CLPS (Commercial Lunar Payload Services). Astrobotic CEO John Thornton sees significant demand and interest from the science community in private lunar exploration.
