NASA Outlines Preliminary Artemis III Mission Plans (News Release)

NASA is moving quickly to define next year’s Artemis III mission in Earth orbit, a crewed flight that will test rendezvous and docking capabilities between the agency’s Orion spacecraft and commercial landers from Blue Origin and SpaceX. Since a February announcement adding an Artemis mission ahead of crewed landing missions to the Moon’s South Pole region, engineers have been evaluating mission profile options and operational considerations for Artemis III to ensure that the test flight helps the agency and its partners reduce risk ahead of the next Americans landing on the Moon during Artemis IV.

“While this is a mission to Earth orbit, it is an important stepping stone to successfully landing on the Moon with Artemis IV. Artemis III is one of the most highly complex missions NASA has undertaken,” said Jeremy Parsons, Moon to Mars acting assistant deputy administrator, NASA’s Exploration Systems Development Mission Directorate in Washington. “For the first time, NASA will coordinate a launch campaign involving multiple spacecraft integrating new capabilities into Artemis operations. We’re integrating more partners and interrelated operations into this mission by design, which will help us learn how Orion, the crew, and ground teams all interact together with hardware and teams from both lander providers before we send astronauts to the Moon’s surface and build a Moon Base there.”

The mission is planned to carry out a series of objectives designed to demonstrate critical systems needed for a future lunar landing. During the Artemis III mission, the SLS (Space Launch System) rocket will launch the Orion spacecraft from NASA’s Kennedy Space Center in Florida with four crew members. Instead of using the interim cryogenic propulsion stage as the upper stage of the rocket, NASA will use a “spacer,” a representation of the mass and overall dimensions of an upper stage but without propulsive capabilities.

The spacer will maintain the same overall dimensions and interface connection points as the upper stage between the Orion stage adapter and launch vehicle stage adapter.

Design and fabrication activities for the spacer are progressing rapidly at NASA’s Marshall Space Flight Center in Huntsville, Alabama. Material for the barrel section and the upper and lower rings is currently being machined at Marshall in preparation for upcoming welding operations.

After the rocket delivers Orion to orbit, the spacecraft’s European-built service module will provide propulsion to circularize Orion’s orbit around the planet in low-Earth orbit. This orbit increases overall mission success by allowing more launch opportunities for each element as compared to a lunar mission — SLS carrying Orion and its crew, SpaceX’s Starship human landing system pathfinder, and Blue Origin’s Blue Moon Mark 2 human landing system pathfinder.

Informed by Blue Origin and SpaceX capabilities, NASA is also defining the concept of operations for the mission. While some decisions are yet to be determined, astronauts could potentially enter at least one lander test article.

The crew will spend more time aboard Orion than during Artemis II, further advancing the evaluation of life support systems, and for the first time will demonstrate the docking system performance. The mission will inform lander rendezvous and habitation concepts and mission operations in preparation for future surface missions. The agency also plans to test an upgraded heat shield during Orion’s return to Earth to enable more flexible and robust reentry profiles for future missions.

Over the coming weeks, NASA will continue to refine specific plans for the flight, including a timeline for identifying astronauts to train for mission operations, options to evaluate Axiom’s AxEMU spacesuit lander interfaces ahead of lunar surface missions, mission duration, and potential science operations for the flight. NASA has asked for industry input on potential solutions to improve the communications with the ground during the mission since the Deep Space Network will not be used. The agency is also seeking both international and domestic interest in potentially flying CubeSats to deploy in Earth orbit, and may share other opportunities as the concept of operations for the mission is further defined.

As part of the Golden Age of innovation and exploration, NASA will send Artemis astronauts on increasingly difficult missions to explore more of the Moon for scientific discovery, economic benefits, establish an enduring human presence on the lunar surface, and to build on our foundation for the first crewed missions to Mars.

The Latest Update on an Artemis Lunar Lander...

Blue Origin Moon Lander Completes Testing at NASA Vacuum Chamber (News Release - May 4)

Also known as Endurance, MK1 is an uncrewed cargo lander funded by Blue Origin as a commercial demonstration mission to advance Human Landing System capabilities in support of NASA’s Artemis program. The tests in Chamber A represent a public-private partnership model, with Blue Origin conducting work through a reimbursable Space Act Agreement.

Endurance will demonstrate precision landing, cryogenic propulsion, and autonomous guidance, navigation, and control capabilities in support of future lunar surface operations. In addition to its primary objectives, MK1 will carry two NASA science and technology payloads under the CLPS (Commercial Lunar Payload Services) initiative to the lunar South Pole region this year: the Stereo Cameras for Lunar Plume-Surface Studies, an array of high-resolution cameras that will collect imagery of the interaction between the lander’s engine plume and the lunar surface during descent and landing, and the Laser Retroreflective Array, which helps orbiting spacecraft determine a more precise location using reflected laser light.

Through CLPS, NASA partners with American companies to deliver science investigations and technology demonstrations to the Moon, advancing understanding of the lunar environment and supporting future crewed missions as part of the agency’s Artemis campaign.

Testing in NASA Johnson’s Chamber A, one of the world’s largest thermal vacuum test facilities, enabled engineers to model the vacuum of space and the extreme temperature conditions that the spacecraft would experience during flight. By recreating these conditions on the ground, teams evaluated system performance and verified structural and thermal integrity prior to launch. NASA and Blue Origin will incorporate lessons learned from MK1’s design, integration and testing to support NASA’s future Artemis missions that will return American astronauts to the Moon.

MK1’s development contributes to technology maturation and risk reduction for future human-class systems, including Blue Moon Mark 2 (MK2), a larger crewed landing system designed to safely transport astronauts from lunar orbit to the surface and back, enabling sustained human exploration at the Moon’s South Pole region.

Testing of MK1 at NASA Johnson is enabled through the agency’s “front door” approach — a coordinated process that provides commercial partners access to NASA facilities and technical expertise while maintaining safety, mission assurance, and alignment with agency objectives.

NASA Welcomes Ireland as Newest Artemis Accords Signatory (News Release)

Ireland signed the Artemis Accords on Monday during a signing ceremony hosted by NASA, becoming the latest nation to commit to the responsible exploration of space for all humanity.

Ireland, a longstanding member of ESA (European Space Agency) and a valued international partner for NASA, now joins all 23 ESA member states as a signatory of the Artemis Accords.

“It is my privilege to welcome Ireland as the 66th and newest signatory to the Artemis Accords,” said NASA Administrator Jared Isaacman during remarks. “The Emerald Isle is now part of a growing community of like-minded nations committed to the peaceful, transparent and responsible exploration of space. Ireland joins at a pivotal moment. Artemis II was the opening act in humanity’s return to the Moon. What comes next is a sustained campaign of missions that will take us back to the lunar surface, not just for flags and footprints, but to build a base and stay.”

Underscoring the longstanding cultural ties and shared heritage between the United States and Ireland, the signing was celebrated during a ceremony at NASA Headquarters in Washington attended by U.S. Congressional staffers and interagency representatives.

Ireland’s Minister for Enterprise, Tourism and Employment Peter Burke, T.D., signed on behalf of the country.

“From an island shaped by the sea, whose people have always looked beyond the horizon and journeyed across the world, forging connections far beyond our shores, Ireland is proud to bring that same spirit to a new frontier and to join a global community committed to the peaceful exploration of space,” said Burke.

Ambassador of Ireland to the United States of America Geraldine Byrne Nason and Chief of Staff in the Office of the Under Secretary for Economic Affairs William Cappelletti, U.S. Department of State, participated in the event. U.S. Ambassador to Ireland Edward Walsh also attended.

In 2020, the United States, led by NASA and the U.S. Department of State, joined with seven other founding nations to establish the Artemis Accords, responding to the growing interest in lunar activities by both governments and private companies.

The Artemis Accords introduced the first set of practical principles aimed at enhancing the safety and coordination between like-minded nations as they explore the Moon, Mars and beyond.

Signing the Artemis Accords means committing to explore peaceably and transparently, to render aid to those in need, to enable access to scientific data that all of humanity can learn from, to ensure activities do not interfere with those of others, and to preserve historically-significant sites and artifacts by developing best practices for space exploration for the benefit of all.

More countries are expected to sign the Artemis Accords in the months and years ahead, as NASA continues its work to establish a safe, peaceful and prosperous future in space.
