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.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Artemis I Moon Tree seedlings continue to find new homes with schools, museums, libraries, universities, and community organizations across the contiguous United States. An open call to NASA’s Artifacts Module in Fall, 2023 welcomed over 1000 organization submissions, which were reviewed and ranked by a joint USDA Forest Service and NASA panel.
Final recipient selection and seedling assignments for each cycle are informed by rank and region, and subject to a limited inventory of trees germinated from each of the five species of seeds flown aboard Artemis I in 2022. Recipient selection and seedling distribution follows four cycles: Spring 2024, Fall 2024, Spring 2025, and Fall 2025.

Margin’ up the Crater Rim!
NASA’s Mars rover Perseverance conducts proximity science on the Eremita Mesa abrasion patch in the Margin Unit on Sept. 6, 2024, as it continues its traverse up the rim of Jezero Crater. Perseverance acquired the image using its Front Left Hazard Avoidance Camera A (Hazcam) on sol 1261 — Martian day 1,261 of the Mars 2020 mission — at the local mean solar time of 13:53:53. NASA/JPL-Caltech To conclude its exploration of the mysterious margin unit before it ascends the rim of Jezero Crater, Perseverance made one last stop this past week to investigate these strange rocks at “Eremita Mesa.”
Since beginning its steep drive up the crater rim, Perseverance has been traversing along the edge of the margin unit (the margin of the margin!), an enigmatic unit rich in carbonates, a mineral group closely linked to habitability. Here, the rover team scouted out a mound of rock called “Specter Chasm,” where Perseverance cleared away the dusty, weathered surface with its trusty abrading bit. The resulting abraded patch, called Eremita Mesa, is pictured above being investigated by Perseverance’s proximity science instruments mounted on its robotic arm. This includes taking close-up images to examine the millimeter-scale particles that make up the rock, using the WATSON (Wide Angle Topographic Sensor for Operations and eNgineering) camera, which functions as Perseverance’s magnifying glass.
Before the rover began exploring, investigations using orbital satellite data had suggested the margin unit rocks may have formed in several different ways. Theories the team has been exploring include that the unit formed on the shoreline of the ancient lake that once filled Jezero Crater, or instead that it was produced by volcanic processes such as pyroclastic flows or ashfall, or ancient lavas flowing into the crater. Since Perseverance began its investigation of the unit in September 2023, more than 350 sols ago (1 sol = 1 Mars day), the Science Team has been scouring data collected by the rover’s instruments to help constrain the unit’s origin. So far, this has remained largely a mystery, with the original rock textures potentially heavily affected by alteration since it formed more than 3 billion years ago. Perseverance has already collected three exciting samples of this curious rock unit for future Earth return: “Pelican Point,” “Lefroy Bay,” and “Comet Geyser,” and the team is hoping the data collected at Eremita Mesa could help further constrain the ancient processes on Mars that formed these strange rocks.
Next, it’s onwards and upwards for Perseverance as it faces a steep climb up the crater rim, where perhaps even more exotic and exciting rocks await!

Perseverance Kicks off the Crater Rim Campaign!
Mastcam-Z mosaic made of 59 individual Mastcam-Z images showing the area Perseverance will climb in the coming weeks on its way to Dox Castle, the rover’s first stop on the crater rim. NASA/JPL-Caltech/ASU/MSSS Perseverance is officially headed into a new phase of scientific investigation on the Jezero Crater rim!
For the last 2 months, the Perseverance rover has been exploring the Neretva Vallis region of Jezero Crater, where rocks with interesting popcorn-like textures and “leopard spot” patterns have fascinated us all. Now, the rover has begun its long ascent up the crater rim, and is officially kicking off a new phase of exploration for the mission.
Strategic (longer-term) planning is particularly important for the Mars 2020 mission given the crucial role Perseverance plays in collecting samples for Mars Sample Return, and the Mars 2020 team undertakes this planning in the form of campaigns. Perseverance has now completed four such campaigns— the Crater Floor, Delta Front, Upper Fan and Margin Unit campaigns respectively— making the Crater Rim Campaign next in line. Given its broad scope and the wide diversity of rocks we expect to encounter and sample along the way, it may be the most ambitious campaign the team has attempted so far.
The team also has less information from orbiter data to go on compared to previous campaigns, because this area of the crater rim does not have the high-resolution, hyperspectral imaging of CRISM that helped inform much of our geological unit distinctions inside the crater. This means that Mastcam-Z multispectral and SuperCam long-distance imaging will be particularly useful for understanding broadscale mineralogical distinctions between rocks as we traverse the crater rim. Such imaging has already proved extremely useful in the Neretva Vallis area, where at Alsap Butte we observed rocks that appeared similar to each other in initial imaging, but actually display an Andy-Warhol-esque array of color in multispectral products, indicative of varied mineral signatures.
Our next stop is Dox Castle where Perseverance will investigate the contact between the Margin Unit and the Crater rim, as well as rubbly material that may be our first encounter with deposits generated during the impact that created Jezero crater itself. Later in the campaign, we will investigate other light-toned outcrops that may or may not be similar to those encountered at Bright Angel, as well as rocks thought to be part of the regionally extensive olivine-carbonate-bearing unit, and whose relationship to both Séítah and the Margin Unit remains an interesting story to unravel. Throughout this next phase of exploration, comparing and contrasting the rocks we see on the rim to both each other and those previously explored in the mission will be an important part of our scientific investigations.
The whole Mars 2020 science team is incredibly excited to be embarking on the next phase of Perseverance’s adventure, and we expect these results, and the samples we collect along the way, to inform our understanding of not just Jezero itself, but the planet Mars as a whole. We can’t wait to share what we find!

ESA/Hubble & NASA, I. Chilingari The subject of this NASA/ESA Hubble Space Telescope image is situated in the Perseus Cluster, also known as Abell 426, 320 million light-years from Earth. It’s a barred spiral galaxy known as MCG+07-07-072, seen here among a number of photobombing stars that are much closer to Earth than it is.
MCG+07-07-072 has quite an unusual shape for a spiral galaxy, with thin arms emerging from the ends of its barred core to draw a near-circle around its disk. It is classified as an SBc(r) galaxy: the c denotes that its two spiral arms are loosely wound, each only performing a half-turn around the galaxy, and the (r) is for the ring-like structure they create.
Rings in galaxies come in quite a few forms, from merely uncommon, to rare and scientifically important! Lenticular galaxies are a type that sit between elliptical and spiral galaxies. They feature a large disk, unlike an elliptical galaxy, but lack any spiral arms. Lenticular means lens-shaped, and these galaxies often feature ring-like shapes in their disks.
Meanwhile, the classification of “ring galaxy” is reserved for peculiar galaxies with a round ring of gas and star formation, much like spiral arms look, but completely disconnected from the galactic nucleus — or even without any visible nucleus! They’re thought to be formed in galactic collisions. Finally, there are the famous gravitational lenses, where the ring is in fact a distorted image of a distant, background galaxy, formed by the ‘lens’ galaxy bending light around it. Ring-shaped images, called Einstein rings, only form when the lensing and imaged galaxies are perfectly aligned.
