NASA Commits to Long-term Artemis Missions with Orion Production Contract (Press Release)

NASA is setting in motion the Orion spacecraft production line to support as many as 12 Artemis missions, including the mission that will carry the first woman and next man to the Moon by 2024.

The agency has awarded the Orion Production and Operations Contract (OPOC) to Lockheed Martin of Littleton, Colorado. Spacecraft production for the Orion program, managed at NASA’s Johnson Space Center in Houston, will focus on reusability and building a sustainable presence on the lunar surface.

“This is a great day for the men and women at Johnson Space Center. They are crucial to our national space program, and have an undeniable legacy and record of success in advancing America’s leadership in the human exploration of space,” said Sen. Ted Cruz of Texas. “I am pleased that Administrator Bridenstine has heeded my calls and is taking significant steps to ensure that Johnson continues to grow with the exciting future of manned exploration that lies ahead. More needs to be done, and I look forward to production ramping up in the weeks and months to come and to more opportunities with NASA.”

OPOC is an indefinite-delivery/indefinite-quantity contract that includes a commitment to order a minimum of six and a maximum of 12 Orion spacecraft, with an ordering period through Sept. 30, 2030. Production and operations of the spacecraft for six to 12 missions will establish a core set of capabilities, stabilize the production process, and demonstrate reusability of spacecraft components.

“This contract secures Orion production through the next decade, demonstrating NASA’s commitment to establishing a sustainable presence at the Moon to bring back new knowledge and prepare for sending astronauts to Mars,” said NASA Administrator Jim Bridenstine. “Orion is a highly-capable, state-of-the-art spacecraft, designed specifically for deep space missions with astronauts, and an integral part of NASA’s infrastructure for Artemis missions and future exploration of the solar system.”

With this award, NASA is ordering three Orion spacecraft for Artemis missions III through V for $2.7 billion. The agency plans to order three additional Orion capsules in fiscal year 2022 for Artemis missions VI through VIII, at a total of $1.9 billion. Ordering the spacecraft in groups of three allows NASA to benefit from efficiencies that become available in the supply chain over time – efficiencies that optimize production and lower costs.

Spacecraft reusability – itself a significant cost saver for the agency – will help NASA build the capabilities for sustainable exploration at the Moon and beyond. The long-term plan is to reuse the recovered crew modules at least once. The first phase of reusability will start with Artemis II. Interior components of the spacecraft, such as flight computers and other high value electronics, as well as crew seats and switch panels, will be re-flown on Artemis V. The Artemis III crew module will be re-flown on Artemis VI.

The first six spacecraft will be acquired by cost-plus-incentive-fee ordering. Because the cost of a complex, high-tech system generally decreases over time as the design stabilizes and production processes mature, NASA will negotiate firm-fixed-price orders for future missions to take advantage of the anticipated spacecraft production cost decreases. Furthermore, the cost incentives on the cost-plus-incentive-fee orders are designed to motivate favorable cost performance during early OPOC production and drive substantially lower prices for any subsequent firm-fixed-price orders issued under this contract.

“As the only vehicle capable of deep space exploration, the Orion spacecraft is critical to America’s continued leadership,” said Rep. Brian Babin of Texas. “Today’s announcement signals that we are moving closer towards operation and production. While I look forward to learning more of the details, it’s encouraging to see that this program is moving along as it should be. I am proud of the Orion program team and contractor partners at Johnson Space Center as they move towards getting the vehicle ‘flight ready.’ Without the brilliant minds and extraordinary leadership of the hard-working men and women at Johnson, our country would not be the preeminent spacefaring nation in the world.”

Work under this contract also will support production of NASA’s lunar-orbiting Gateway and evolving mission requirements. Production of certain spacecraft components already designed and qualified for Orion will be provided for Gateway use, eliminating the need for the Gateway Program to develop and qualify similar components.

“The men and women at Johnson Space Center represent the best and brightest scientific minds, and I’m confident with additional Orion spacecraft they will push the limits of exploration to the Moon and beyond,” said Sen. John Cornyn of Texas. “I commend the Trump Administration for recognizing the importance and tradition of Houston as the center of human spaceflight and exploring the next frontier.”

Houston has long been the hub of America’s human space exploration program, from the early days of Gemini, Mercury, and Apollo to Artemis. With NASA’s accelerated return to the Moon, Johnson Space Center now is managing more major human spaceflight programs than ever before. In addition to the Orion program, the Texas facility also manages NASA’s Gateway and International Space Station programs, and is home to the Mission Control Center and America’s astronaut corps – the next moonwalkers. Johnson also manages the agency’s Commercial Lunar Payload Services, the first two deliveries for which are targeted to launch to the Moon in July 2021.

“No other spacecraft in the world can keep humans alive hundreds of thousands of miles from Earth for weeks at a time with the safety features, crew accommodations, technical innovations, and reliability that Orion provides,” said Mark Kirasich, Orion Program manager at Johnson. “With the design and development phase of Orion largely behind us, this new contract will enable us to increase efficiencies, reuse the spacecraft, and bring down the cost of reliably transporting people between Earth and the Gateway.”

NASA is working to land the first woman and next man on the Moon in five years as part of the agency’s Artemis program. Orion, the Space Launch System rocket and Gateway are part of NASA’s backbone for deep space exploration. Work is well underway on both the Artemis I and II Orion spacecraft. Engineers at Kennedy Space Center in Florida have completed and attached the crew and service modules for Artemis I and are preparing the spacecraft for environmental testing. Meanwhile, teams at Kennedy are integrating thousands of parts into the crew module for Artemis II in preparation for the first crewed Artemis mission.

The Artemis program is the next step in human space exploration. It’s part of NASA’s broader Moon to Mars exploration approach, in which we will quickly and sustainably explore the Moon and use what we learn there to enable humanity’s next giant leap, sending astronauts to Mars.

NASA Joins Last of Five Sections for Space Launch System Rocket Stage (News Release)

NASA finished assembling and joining the main structural components for the largest rocket stage the agency has built since the Saturn V that sent Apollo astronauts to the Moon. Engineers at the agency’s Michoud Assembly Facility in New Orleans connected the last of the five sections of the Space Launch System (SLS) rocket core stage on Sept. 19. The stage will produce 2 million pounds of thrust to send Artemis I, the first flight of SLS and NASA’s Orion spacecraft to the Moon.

“NASA has achieved a historic first milestone by completing the final join of the core stage structure for NASA’s Space Launch System, the world’s most powerful rocket,” said Julie Bassler, the NASA SLS stages manager. “Now, to complete the stage, NASA will add the four RS-25 engines and complete the final integrated avionics and propulsion functional tests. This is an exciting time as we finish the first-time production of the complex core stage that will provide the power to send the Artemis I mission to the Moon.”

The last piece added to the stage was the engine section located at the bottom of the 212-foot-tall core stage. To complete the structure, technicians bolted the engine section to the stage’s liquid hydrogen propellant tank, which was recently attached to the other core stage structures. The engine section is one of the most complicated pieces of hardware for the SLS rocket and is the attachment point for the four RS-25 rockets and the two solid rocket boosters that produce a combined 8.8 millions pounds of thrust. The engine section also includes vital systems for mounting, controlling and delivering fuel from the stage’s two liquid propellant tanks to the rocket’s engines. This fall, NASA will work with core stage lead contractor, Boeing, and the RS-25 engine lead contractor, Aerojet Rocketdyne, to attach the four RS-25 engines and connect them to the main propulsion systems inside the engine section.

“Boeing expects to complete final assembly of the Artemis I core stage in December,” said Jennifer Boland-Masterson, Boeing operations direct at MAF. “After we deliver the stage, NASA will transport it on the agency’s Pegasus barge from Michoud to NASA’s Stennis Space Center near Bay St. Louis, Mississippi, for Green Run testing. Our team here at Michoud will continue work with NASA to build, outfit and assemble the core stage for Artemis II, the first mission that will send astronauts to orbit the Moon. Lessons learned and innovations developed in building the first core stage are making the second one progress much faster.”

During Green Run testing, engineers will install the core stage into the B-2 Test Stand at Stennis for a series of tests that will build like a crescendo over several months. This will be the first fully fueled test of this brand new rocket stage. Many aspects will be carried out for the first time, such as fueling and pressurizing the stage, and the test series culminates with firing up all four engines to demonstrate that the engines, tanks, fuel lines, valves, pressurization system, and software can all perform together as they will on launch day.

The SLS team also achieved another recent milestone by completing structural testing for the stage’s liquid hydrogen tank. The testing confirmed that the structural design for the tank on the rocket’s initial configuration, called Block 1, can withstand extreme conditions during launch and flight. Teams at NASA’s Marshall Space Flight Center in Huntsville, Alabama, put a test version of the tank through the paces during 37 separate test cases that exceed what engineers expect the SLS rocket to experience. The final test used 80,000 gallons of liquid nitrogen to simulate the cryogenic conditions, or extreme cold, that the liquid hydrogen tank will experience in flight. Testing will continue later this year to show the tank’s structural design is adequate for future designs of the vehicle as it evolves to a Block IB configuration and missions with even greater forces.

In addition to providing propellant and power to get the SLS rocket and Orion spacecraft to space, the core stage houses the flight computers and avionics components that control the first 8 minutes of flight. The avionics system, including the flight computers, completed integrated system level qualification testing showing the components all work together to control the rocket in the Software Integration and Test Facility (SITF) at Marshall. The next step is to test the flight software with all the ground system software, Orion and launch control in the Systems Integration Laboratory at Marshall.

“NASA and our contractor teams are making tremendous progress on every aspect of manufacturing, assembling and testing the complex systems needed to land American astronauts on the lunar surface by 2024,” Bassler said. “I am confident this hard work will result in a rocket that can provide the backbone for deep space transportation to the Moon and ultimately to Mars.”

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, and the Human Landing System 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.

Engine Section for NASA's SLS Rocket Moved for Final Integration (News Release)

Technicians at NASA’s Michoud Assembly Facility in New Orleans moved the engine section for NASA’s Space Launch System (SLS) rocket to another part of the facility on Sept. 3 to prepare it for joining to the rest of the rocket’s core stage. 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.
