Vulcan Centaur Launch Date
United Launch Alliance (ULA) plans to launch the inaugural flight of its Vulcan Centaur rocket with a commercial payload in early 2023. The launch window is expected to open on January 17 and close on February 10. The Vulcan Centaur is an all-new launch vehicle designed to replace ULA’s Atlas V and Delta IV rockets.
Vulcan Centaur Payload Capacity
Vulcan Centaur, a next-generation launch vehicle developed by United Launch Alliance, boasts impressive payload capacities designed to accommodate the diverse needs of various missions. The vehicle features two primary configurations:
- Vulcan Centaur VC-1: Able to lift payloads of up to 19 metric tons to low Earth orbit (LEO) and beyond.
- Vulcan Centaur VC-2: Capable of carrying payloads of up to 27 metric tons to geostationary transfer orbit (GTO) and higher.
The Centaur upper stage of Vulcan Centaur is equipped with two RL-10 engines, known for their reliability and efficiency. This configuration provides the necessary thrust and specific impulse to place payloads into their desired orbits.
Vulcan Centaur’s payload capacity meets the demanding requirements of government missions, commercial satellites, and deep space exploration initiatives. Its ability to handle heavy payloads enables the launch of complex spacecraft, scientific instruments, and lunar landers, supporting a wide range of missions.
Vulcan Centaur Engine Performance
The Vulcan Centaur engine, developed and manufactured by Blue Origin, is a high-performance, liquid-fueled rocket engine designed for use in launch vehicles. Here is a summary of its key performance characteristics:
- Thrust: Approximately 2,153,000 pounds (9.6 MN) at sea level
- Specific Impulse: 335 seconds (vac)
- Burn Time: Up to 500 seconds
- Propellants: Liquid hydrogen (LH2) and liquid oxygen (LOX)
- Throttleability: 100% to 30%
- Reusability: Variable, depending on operating conditions
- Reliability: Extensive testing and analysis to ensure high reliability
- Efficiency: Advanced design and materials to optimize performance
United Launch Alliance Vulcan Centaur
The Vulcan Centaur is a two-stage rocket developed by United Launch Alliance (ULA) as a replacement for the Atlas V and Delta IV Heavy rockets. It consists of a first stage powered by two BE-4 engines and a second stage powered by a single RL-10 engine. The Centaur upper stage is a Lockheed Martin product that has been used on previous ULA rockets.
The Vulcan Centaur is capable of lifting payloads of up to 15,000 kg (33,000 lb) to low Earth orbit (LEO) and 5,500 kg (12,000 lb) to geostationary orbit (GEO). It is designed to be more efficient and cost-effective than its predecessors and has multiple payload fairing options to accommodate a variety of satellite sizes.
The Vulcan Centaur is scheduled to make its maiden flight in 2023 and is expected to become the primary launch vehicle for ULA’s government and commercial customers.

SpaceX Launch from CCAFS
SpaceX successfully launched its latest Falcon 9 rocket from Cape Canaveral Air Force Station (CCAFS) in Florida. The mission, carrying a communications satellite for Intelsat, marked the 20th launch of a Falcon 9 rocket from CCAFS this year.
Liftoff occurred at 8:22 p.m. EST on December 19, 2023. The rocket ascended through the atmosphere, deploying its first stage booster back to Earth for landing at SpaceX’s nearby landing zone in Cape Canaveral.
The second stage of the Falcon 9 continued to orbit and successfully deployed the Intelsat G-33/GX-101 satellite into its intended orbit approximately 35 minutes after liftoff. The satellite will provide high-speed broadband connectivity to underserved areas around the globe.
This launch represents a significant milestone for SpaceX, demonstrating the reliability and frequency of its Falcon 9 launches. The company plans to continue launching rockets from CCAFS in the coming months and years, supporting various commercial and government missions.
CCAFS Space Launch Complex 41 History
The Cape Canaveral Space Force Station’s Space Launch Complex 41 (SLC-41) has a long and illustrious history, playing a pivotal role in the U.S. space program.
- 1960-1963: SLC-41 was constructed as a launch pad for the Atlas-Agena rocket, which carried the Mercury spacecraft. It supported the Mercury missions that sent the first American astronauts into space.
- 1964-1965: The complex was modified to accommodate the Atlas-Centaur rocket, which was used to launch the Surveyor lunar probes and Mariner spacecraft.
- 1966-1973: SLC-41 was used for the Titan III rocket, which carried the Voyager 1 and 2 probes, and the Apollo Lunar Module.
- 1974-1981: The complex underwent significant modifications to support the Space Shuttle program. It became the launch pad for the iconic orbiter Enterprise, as well as 53 operational Space Shuttle missions.
- 2000-2016: After the Space Shuttle program ended, SLC-41 was deactivated and fell into disuse.
- 2018-Present: SpaceX acquired the lease of SLC-41 and has since refurbished and upgraded the complex to support the Falcon 9 and Falcon Heavy rockets.
