Teledyne Brown Completes Major Hardware for NASA’s Artemis Rocket

One of the largest pieces of hardware for NASA’s Space Launch System left Marshall Space Flight Center recently to begin its voyage to Kennedy Space Center in the coming weeks.

Teledyne Brown Engineering, the prime contractor on the project with several small business partners, designed and built the Launch Vehicle Stage Adapter. LVSA provides the fundamental structural strength required to withstand the launch loads and the maximum dynamic pressure.

It also provides the critical separation system used to separate the core stage of the rocket from the second stage, which includes the astronauts in the Orion crew vehicle. The cone-shaped adapter is roughly 30 feet in diameter by 30 feet tall and consists of 16 aluminum-lithium alloy panels.

“LVSA is not only a significant achievement for our company, but it is monumental for Marshall Space Flight Center and the Huntsville Community,” said Jan Hess, president of Teledyne Brown Engineering.  “It’s the largest hardware to be completed for the SLS in Huntsville.

“Our company was an integral part of the country’s first rocket programs with Werner Von Braun, and we continue our legacy and support of space programs with this successful hardware completion for the latest Space Launch System.”

LVSA will be moved by barge to Kennedy Space Center where it will join the rocket’s Core Stage to the ICPS and Upper Stage.  It will be incorporated into the final configuration of the SLS for the first Artemis lunar mission.

The SLS is the only rocket able to send the Orion capsule, cargo and astronauts to the Moon in a combined mission.

The Artemis Mission, including this hardware, will be a part of the first moon landing since Apollo 17 in 1972.

Teledyne is building an LVSA for the second Artemis lunar mission and starting work on the LVSA for the Artemis III mission, which will land the first woman and next man on the Moon in 2024.

NASA Extends Boeing’s Contract to Build More Moon Rockets

 

NASA has taken the next steps toward building Space Launch System (SLS) rocket core stages to support as many as 10 Artemis missions, including the mission that will carry the first woman and next man to the Moon by 2024.

The agency intends to work with Boeing, the current lead contractor for the core stages of the rockets that will fly on the first two Artemis missions, for the production of SLS rockets through the next decade. The core stage is the center part of the rocket that contains the two giant liquid fuel tanks.

Illustration shows NASA’s Space Launch System (SLS) in the Block 1 configuration, which will carry an Orion spacecraft beyond the Moon, on the mobile launcher. SLS is the only rocket that can send the Orion spacecraft, astronauts and supplies to the Moon on a single mission.

Towering 212 feet with a diameter of 27.6 feet, it will store cryogenic liquid hydrogen and liquid oxygen and all the systems that will feed the stage’s four RS-25 engines. It also houses the flight computers and much of the avionics needed to control the rocket’s flight.

The Space Launch System is the backbone of NASA’s deep space human exploration and is the only rocket capable of sending crew, the Orion capsule and heavy cargo to the Moon on a single mission.

“It is urgent that we meet the president’s goal to land astronauts on the Moon by 2024, and SLS is the only rocket that can help us meet that challenge,” said NASA Administrator Jim Bridenstine. “These initial steps allow NASA to start building the core stage that will launch the next astronauts to set foot on the lunar surface and build the powerful exploration upper stage that will expand the possibilities for Artemis missions by sending hardware and cargo along with humans or even heavier cargo needed to explore the Moon or Mars.”

NASA works with Boeing, the current lead contractor for the core stages of the rockets that will fly on the first two Artemis missions. Boeing is completing the first SLS core stage with the second well underway. The order leverages labor, materials, and supply chain efficiencies for production savings.

The SLS is managed at the Marshal Space Flight Center in Huntsville, manufactured at the Michoud Assembly Facility outside of New Orleans and will launch from Cape Canaveral.

NASA has provided initial funding and authorization to Boeing to begin work toward the production of the third core stage and to order targeted long-lead materials and cost-efficient bulk purchases to support future builds of core stages.

“We greatly appreciate the confidence NASA has placed in Boeing to deliver this deep space rocket and their endorsement of our team’s approach to meeting this unprecedented technological and manufacturing challenge in support of NASA’s Artemis program,” said Jim Chilton, senior vice president of Boeing’s Space and Launch division. “Together with a nationwide network of engaged and innovative suppliers we will deliver the first core stage to NASA this year for Artemis I.

“This team is already implementing lessons learned and innovative practices from the first build to produce a second core stage more efficiently than the first.  We are is committed to continuous improvement as they execute on this new contract.”

The contract allows Boeing to order materials that will be used to produce additional SLS rockets through the next decade: 10 SLS core stages and eight Exploration Upper Stages to support Artemis III through Artemis XII. The full contract is expected to support up to 10 core stages and up to eight Exploration Upper Stages (EUS).

“NASA is committed to establishing a sustainable presence at the Moon, and this action enables NASA to continue Space Launch System core stage production in support of that effort to help bring back new knowledge and prepare for sending astronauts to Mars,” said John Honeycutt, SLS Program Manager at Marshall. “SLS is the only rocket powerful enough to send Orion, astronauts and supplies to the Moon on a single mission, and no other rocket in production today can send as much cargo to deep space as the Space Launch System rocket.

For the first three Artemis missions, the SLS rocket uses an interim cryogenic propulsion stage to send the Orion spacecraft to the Moon. The SLS rocket is designed to meet a variety of mission needs by evolving to carry greater mass and volume with a more powerful EUS.

The EUS is an important part of Artemis infrastructure needed to send astronauts and large cargo together, or larger cargo-only shipments, to the Moon, Mars and deep space. NASA aims to use the first EUS on the Artemis IV mission, and additional core stages and upper stages will support either crewed Artemis missions, science missions or cargo missions.

“The exploration upper stage will truly open up the universe by providing even more lift capability to deep space,” said Julie Bassler, the SLS Stages manager at Marshall. “The exploration upper stage will provide the power to send more than 45 metric tons, or 99 thousand pounds, to lunar orbit.”

 

Engine Section for SLS Rocket Moved for Final Integration

NEW ORLEANS — Technicians at NASA’s Michoud Assembly Facility recently moved the engine section for NASA’s Space Launch System (SLS) rocket to another part of the facility to prepare it for joining to the rest of the rocket’s core stage.

The Space Launch System is managed by the Marshall Space Flight Center in Huntsville.

The engine section, which comprises the lowest portion of the 212-foot-tall stage, is the last major component to be horizontally integrated to the core stage. The flight hardware will be used for Artemis I, the first lunar mission of SLS and NASA’s Orion spacecraft.

Crews completed assembly on the engine section on Aug. 29. NASA and Boeing engineers removed the scaffolding surrounding the hardware to use a special tool to properly position the engine section for its attachment to the rest of the stage.

The core stage’s two liquid propellant tanks and four RS-25 engines will produce more than 2 million pounds of thrust to send the SLS rocket and Orion on the Artemis lunar missions. The engine section houses the four RS-25 engines and includes vital systems for mounting, controlling and delivering fuel from the propellant tanks to the rocket’s engines.

NASA is working to land the first woman and the next man on the Moon by 2024.

SLS and NASA’s Orion spacecraft, along with the Gateway in orbit around the Moon, are the backbone for deep space exploration. SLS is the only rocket that can send Orion, astronauts and supplies to the Moon in a single mission.
