Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA employees plant an Artemis Moon Tree at NASA’s Stennis Space Center on Oct. 29 to celebrate NASA’s successful Artemis I mission as the agency prepares for a return around the Moon with astronauts on Artemis II. NASA/Danny Nowlin A tree-planting ceremony at NASA’s Stennis Space Center on Oct. 29 celebrated NASA’s successful Artemis I mission as the agency prepares for a return around the Moon with astronauts on Artemis II.
“We already have a thriving Moon Tree from the Apollo years onsite,” NASA Stennis Director John Bailey said. “It is exciting to add trees for our new Artemis Generation as it continues the next great era of human space exploration.”
NASA’s Office of STEM Engagement Next Gen STEM Project partnered with U.S. Department of Agriculture (USDA) Forest Service to fly five species of tree seeds aboard the Orion spacecraft during the successful uncrewed Artemis I test flight in 2022 as part of a national STEM Engagement and conservation education initiative.
The Artemis Moon Tree species included sweetgums, loblolly pines, sycamores, Douglas-firs, and giant sequoias. The seeds from the first Artemis mission have been nurtured by the USDA into seedlings to be a source of inspiration for the Artemis Generation.
The Moon Tree education initiative is rooted in the legacy of Apollo 14 Moon Tree seeds flown in lunar orbit over 50 years ago by the late Stuart Roosa, a NASA astronaut and Mississippi Coast resident.
NASA Stennis and the NASA Shared Services Center (NSSC), located at the site, planted companion trees during the Oct. 29 ceremony. Bailey and NSSC Executive Director Anita Harrell participated in a joint planting ceremony attended by a number of employees from each entity.
The American sweetgum trees are the second and third Moon Trees at the south Mississippi site. In 2004, ASTRO CAMP participants planted a sycamore Moon Tree to honor the 35th anniversary of Apollo 11 and the first lunar landing on July 20, 1969.
The road to space for both Apollo 14 and Artemis I went through Mississippi. Until 1970, NASA Stennis test fired first, and second stages of the Saturn V rockets used for Apollo.
NASA Stennis now tests all the RS-25 engines powering Artemis missions to the Moon and beyond. Prior to Artemis I, NASA Stennis tested the SLS (Space Launch System) core stage and its four RS-25 engines.
The Artemis Moon Trees have found new homes in over 150 communities and counting since last spring, and each of the 10 NASA centers also will plant one.
As the tree grows at NASA Stennis, so, too, does anticipation for the first crewed mission with Artemis II. Four astronauts will venture around the Moon on NASA’s path to establishing a long-term presence at the Moon for science and exploration.
The flight will test NASA’s foundational human deep space exploration capabilities – the SLS rocket and Orion spacecraft – for the first time with astronauts.

The background image of the lunar South Pole terrain within the nine regions is a mosaic of LRO (Lunar Reconnaissance Orbiter) WAC (Wide Angle Camera) images.Credit: NASA As NASA prepares for the first crewed Moon landing in more than five decades, the agency has identified an updated set of nine potential landing regions near the lunar South Pole for its Artemis III mission. These areas will be further investigated through scientific and engineering study. NASA will continue to survey potential areas for missions following Artemis III, including areas beyond these nine regions.
“Artemis will return humanity to the Moon and visit unexplored areas. NASA’s selection of these regions shows our commitment to landing crew safely near the lunar South Pole, where they will help uncover new scientific discoveries and learn to live on the lunar surface,” said Lakiesha Hawkins, assistant deputy associate administrator, Moon to Mars Program Office.
NASA’s Cross Agency Site Selection Analysis team, working closely with science and industry partners, added, and excluded potential landing regions, which were assessed for their science value and mission availability.
The refined candidate Artemis III lunar landing regions are, in no priority order:
Peak near Cabeus B Haworth Malapert Massif Mons Mouton Plateau Mons Mouton Nobile Rim 1 Nobile Rim 2 de Gerlache Rim 2 Slater Plain These regions contain diverse geological characteristics and offer flexibility for mission availability. The lunar South Pole has never been explored by a crewed mission and contains permanently shadowed areas that can preserve resources, including water.
“The Moon’s South Pole is a completely different environment than where we landed during the Apollo missions,” said Sarah Noble, Artemis lunar science lead at NASA Headquarters in Washington. “It offers access to some of the Moon’s oldest terrain, as well as cold, shadowed regions that may contain water and other compounds. Any of these landing regions will enable us to do amazing science and make new discoveries.”
To select these landing regions, a multidisciplinary team of scientists and engineers analyzed the lunar South Pole region using data from NASA’s Lunar Reconnaissance Orbiter and a vast body of lunar science research. Factors in the selection process included science potential, launch window availability, terrain suitability, communication capabilities with Earth, and lighting conditions. Additionally, the team assessed the combined trajectory capabilities of NASA’s SLS (Space Launch System) rocket, the Orion spacecraft, and Starship HLS (Human Landing System) to ensure safe and accessible landing sites.
The Artemis III geology team evaluated the landing regions for their scientific promise. Sites within each of the nine identified regions have the potential to provide key new insights into our understanding of rocky planets, lunar resources, and the history of our solar system.
“Artemis III will be the first time that astronauts will land in the south polar region of the Moon. They will be flying on a new lander into a terrain that is unique from our past Apollo experience,” said Jacob Bleacher, NASA’s chief exploration scientist. “Finding the right locations for this historic moment begins with identifying safe places for this first landing, and then trying to match that with opportunities for science from this new place on the Moon.”
NASA’s site assessment team will engage the lunar science community through conferences and workshops to gather data, build geologic maps, and assess the regional geology of eventual landing sites. The team also will continue surveying the entire lunar South Pole region for science value and mission availability for future Artemis missions. This will include planning for expanded science opportunities during Artemis IV, and suitability for the LTV (Lunar Terrain Vehicle) as part of Artemis V.
The agency will select sites within regions for Artemis III after it identifies the mission’s target launch dates, which dictate transfer trajectories, or orbital paths, and surface environment conditions.
Under NASA’s Artemis campaign, the agency will establish the foundation for long-term scientific exploration at the Moon, land the first woman, first person of color, and its first international partner astronaut on the lunar surface, and prepare for human expeditions to Mars for the benefit of all.

From left to right, Chilean Ambassador to the United States Juan Gabriel Valdés, Chilean Minister of Science, Technology, Knowledge, and Innovation Aisén Etcheverry Escudero, NASA Administrator Bill Nelson, and United States Department of State Acting Assistant Secretary in the Bureau of Oceans and International Environmental and Scientific Affairs Jennifer R. Littlejohn pose for a photo after the signing of the Artemis Accords, Friday, Oct. 25, 2024, at the Mary W. Jackson NASA Headquarters building in Washington. The Republic of Chile is the 47th country to sign the Artemis Accords, which establish a practical set of principles to guide space exploration cooperation among nations participating in NASA’s Artemis program. NASA/Keegan Barber Chile signed the Artemis Accords Friday during a ceremony hosted by NASA Administrator Bill Nelson at the agency’s headquarters in Washington, becoming the 47th nation and the seventh South American country to commit to the responsible exploration of space for all humanity.
“Today we welcome Chile’s signing of the Artemis Accords and its commitment to the shared values of all the signatories for the exploration of space,” said Nelson. “The United States has long studied the stars from Chile’s great Atacama Desert. Now we will go to the stars together, safely, and responsibly, and create new opportunities for international cooperation and the Artemis Generation.”
Aisén Etcheverry, minister of science, technology, knowledge and innovation, signed the Artemis Accords on behalf of Chile. Jennifer Littlejohn, acting assistant secretary, Bureau of Oceans and International Environmental and Scientific Affairs, U.S. Department of State, and Juan Gabriel Valdés, ambassador of Chile to the United States, also participated in the event.
“The signing marks a significant milestone for Chile, particularly as our government is committed to advancing technological development as a key pillar of our national strategy,” said Etcheverry. “Chile has the opportunity to engage in the design and development of world-leading scientific and technological projects. Moreover, this collaboration allows us to contribute to areas of scientific excellence where Chile has distinguished expertise, such as astrobiology, geology, and mineralogy, all of which are critical for the exploration and colonization of space.”
Earlier in the day, Nelson also hosted the Dominican Republic at NASA Headquarters to recognize the country’s signing of the Artemis Accords Oct. 4. Sonia Guzmán, ambassador of the Dominican Republic to the United States, delivered the signed Artemis Accords to the NASA administrator. Mike Overby, acting deputy assistant secretary, Bureau of Oceans and International Environmental and Scientific Affairs, U.S. Department of State, and other NASA officials attended the event.
In 2020, the United States, led by NASA and the U.S. Department of State, and seven other initial signatory nations established the Artemis Accords, identifying an early set of principles promoting the beneficial use of space for humanity. The Artemis Accords are grounded in the Outer Space Treaty and other agreements including the Registration Convention, the Rescue and Return Agreement, as well as best practices and norms of responsible behavior that NASA and its partners have supported, including the public release of scientific data.
The commitments of the Artemis Accords and efforts by the signatories to advance implementation of these principles support the safe and sustainable exploration of space. More countries are expected to sign in the coming weeks and months.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s Stennis Space Center near Bay St. Louis, Mississippi, achieved a key milestone this week for testing a new SLS (Space Launch System) rocket stage to fly on future Artemis missions to the Moon and beyond.
Over a two-week period beginning Oct. 10, crews completed a safe lift and installation of the interstage simulator component needed for future testing of NASA’s exploration upper stage (EUS) in the B-2 position of the Thad Cochran Test Stand. The component will function like the SLS interstage section that helps protect the upper stage during Artemis launches.
“NASA Stennis is at the front end of the critical path for future space exploration,” said Barry Robinson, project manager for exploration upper stage Green Run testing on the Thad Cochran Test Stand. “Installing the interstage simulator is a significant step in our preparation to ensure the new, more powerful upper stage is ready to safely fly on future Artemis missions.”

The new stage will replace the current interim cryogenic propulsion stage on the Block 1 version of SLS, which features a single engine and is capable of lifting 27 tons of crew and cargo to lunar orbit.
The new exploration upper stage will be powered by four RL10 engines, manufactured by SLS engines contractor L3Harris. It will increase payload capacity by 40%, enabling NASA to send 38 tons of cargo with a crew to the Moon or 42 tons of cargo without a crew.
In the first two weeks of October 2024, crews at NASA’s Stennis Space Center completed a successful lift and installation of an interstage simulator unit on the B-2 side of the Thad Cochran test Stand. The interstage simulator is a key component for future testing of NASA’s new exploration upper stage that will fly on Artemis missions to the Moon and beyond. Before the first flight of the exploration upper stage on the Artemis IV mission, the stage will undergo a series of Green Run tests of its integrated systems at NASA Stennis. The test series will culminate with a hot fire of the stage’s four RL10 engines, just as during an actual mission.
The simulator component installed on the Thad Cochran Test Stand (B-2) at NASA Stennis weighs 103 tons and measures 31 feet in diameter and 33 feet tall. It will function like the SLS interstage section to protect EUS electrical and propulsion systems during Green Run testing. The top portion of the simulator also will serve as a thrust takeout system to absorb the thrust of the EUS hot fire and transfer it back to the test stand. The four-engine EUS provides more than 97,000 pounds of thrust.

It is now outfitted with all piping, tubing, and electrical systems necessary to support future Green Run testing.
Installation onto the test stand enables NASA Stennis crews to begin fabricating the mechanical and electrical systems connecting the facility to the simulator. As fabrication of the systems are completed, crews will conduct activation flows to ensure the test stand can operate to meet test requirements.
Through Artemis, NASA will establish the foundation for long-term scientific exploration at the Moon; land the first woman, first person of color and first international partner astronaut on the lunar surface; and prepare for human expeditions to Mars for the benefit of all.
