NASA/Sam Lott Engineers and technicians at NASA’s Marshall Space Flight Center in Huntsville, Alabama, recently installed a key component called the frangible joint assembly onto the adapter that connects the core stage to the upper part of the NASA’s SLS (Space Launch System) rocket. The cone-shaped stage adapter, called the launch vehicle stage adapter, will be part of the SLS mega rocket that will power NASA’s Artemis III mission to the Moon. The frangible joint sits atop the adapter and operates as a separation mechanism. The frangible joint is designed to break apart upon command, allowing the upper part of the rocket, NASA’s Orion spacecraft, and the crew inside Orion to quickly separate from the SLS core stage and adapter. Frangible joint assemblies are widely used across the space industry in a variety of crewed and uncrewed spacecraft to efficiently separate fairings or stages during launch, during ascent, in orbit and during payload deployment. The stage adapter used for Artemis III is set to be the last of its kind as SLS evolves into a larger and more powerful configuration for future Artemis missions, beginning with Artemis IV. The adapter is fully assembled at Marshall by NASA and lead contractor Teledyne Brown, which is also based in Huntsville.

NASA During a ceremony in Washington Nov. 30, Angola became the 33rd country to sign the Artemis Accords.
The Artemis Accords establish a practical set of principles to guide space exploration cooperation among nations, including those participating in NASA’s Artemis program.
NASA, in coordination with the U.S. Department of State, established the Artemis Accords in 2020 together with seven other original signatories. Since then, the Accords signatories have held focused discussions on how best to implement the Artemis Accords principles.
The Artemis Accords reinforce and implement key obligations in the 1967 Outer Space Treaty. They also strengthen the commitment by the United States and signatory nations to the Registration Convention, the Rescue and Return Agreement, as well as best practices and norms of responsible behavior NASA and its partners have supported, including the public release of scientific data.
More countries are expected to sign the Artemis Accords in the months and years ahead, as NASA continues to work with its international partners to establish a safe, peaceful, and prosperous future in space. Working with both new and existing partners adds new energy and capabilities to ensure the entire world can benefit from our journey of exploration and discovery.

Erickson to Retire after Over 40 Years of Service
December 1, 2023
It is my pleasure to share information about new hires within NASA’s Science Mission Directorate (SMD) on this blog, and it is also my bittersweet duty to share information about retirements. After 40 years with NASA, Kristen Erickson – Director of NASA Science Engagement & Partnerships Division — will retire at the end of 2023.
Kristen has made many contributions to the agency. Over the years she has mentored dozens of scientists and engineers to carry on NASA’s legacy of sharing the science with audiences of all ages. Kristen started her career at the Johnson Space Center in Houston, Texas, in 1983. After witnessing the Space Shuttle Challenger tragedy, she transferred to NASA Headquarters in Washington for Return to Flight and led the Space Operations Business office for nine years during the heyday of the Space Shuttle Program when eight missions per year were flown.
After graduating from Harvard’s Kennedy School on a NASA fellowship, she returned to work for at NASA Headquarters. She was chosen as the lead management executive for the new Office of Biological and Physical Research – which has since joined as a division in the Science Mission Directorate. She then moved to leading the new Office of Communications Planning under then Deputy Administrator, Shana Dale, where her role was to forge a more cohesive strategic public engagement environment. Her work there included leading the agency’s 50th anniversary activities, including “NASA at the Smithsonian Folklife Festival,” Future Forums to engage top-tier community leaders, and the Apollo 40th Anniversary events.
Kristen brought those goals of working for a more integrated approach to engaging with audiences to her new job with NASA science in 2009. There she created the Year of the Solar System campaign to transition awareness and excitement post-Space Shuttle to science events and missions. Comet encounters, Venus transiting of the Sun, science launches, and the historic landing of Curiosity Rover on Mars – all broke engagement records and helped show that working together on a common theme (and using data to drive decisions) was better than a siloed approach.
In addition to integrating messages and plans, Kristen worked hard to create integrated working groups as well. She helped create robust teams of diverse individuals, whose different skills and expertise combined together to pull off giant and complex projects.
One such project was NASA’s 2017 total solar eclipse communications efforts, which engaged over 88% of the US adult population and still holds agency records – though Kristen says she hopes those records will soon be broken with the upcoming April 8, 2024, eclipse broadcast.
When asked to say something about her career, Kristen said: “The power of the NASA team to do the impossible never fails to inspire, especially when all feel included in the process.”
I wish her luck in the next phase of her life and know that her legacy lives on with a robust team of science engagement experts – whose integrated skills will continue to bring NASA science to learners of all ages.

December’s Night Sky Notes: A Flame in the Sky – the Orion Nebula
Orion constellation Stellarium Web by Kat Troche of the Astronomical Society of the Pacific
It’s that time of year again: Winter! Here in the Northern Hemisphere, the clear, crisp sky offers spectacular views of various objects, the most famous of all being Orion the Hunter.
As we’ve previously mentioned, Orion is a great way to test your sky darkness. With the naked eye, you can easily spot this hourglass-shaped constellation. Known as an epic hunter in Greco-Roman antiqity, Orion and all its parts have many names and meanings across many cultures. In Egyptian mythology, this constellation represented the god Sah. The Babylonians referred to it as The Heavenly Shepard. In most cultures, it is Orion’s Belt that has many stories: Shen in Chinese folklore, or Tayamnicankhu in Lakota storytelling. But the Maya of Mesoamerica believed that part of Orion contained The Cosmic Hearth – the fire of creation.
1,500 light years away from Earth sits the star-forming region, and crown jewel of Orion – Messier 42 (M42), the Orion Nebula. Part of the “sword” of Orion, this 24 light year wide cloud of dust and gas sits below the first star in Orion’s Belt, Alnitak, and can easily be spotted with the naked eye under moderate dark skies. You can also use binoculars or a telescope to resolve more details, such as the Trapezium: four stars in the shape of a keystone (or baseball diamond). These young stars make up the core of this magnificent object.
Of course, it’s not just for looking at! M42 is easily one of the most photographed nebulae around, imaged by amateur astrophotographers, professional observatories and space telescopes alike. It has long been a place of interest for the Hubble, Spitzer, and Chandra X-ray Space Telescopes, with James Webb Space Telescope now joining the list in February 2023. Earlier this year, NASA and the European Space Agency released a new photo of the Orion Nebula taken from JWST’s NIRCam (Near-Infrared Camera), which allowed scientists to image this early star forming region in both short and long wavelengths.
These Webb images show a part of the Orion Nebula known as the Orion Bar. It is a region where energetic ultraviolet light from the Trapezium Cluster — located off the upper-left corner — interacts with dense molecular clouds. The energy of the stellar radiation is slowly eroding the Orion Bar, and this has a profound effect on the molecules and chemistry in the protoplanetary disks that have formed around newborn stars here. The largest image, on the left, is from Webb’s NIRCam (Near-Infrared Camera) instrument. At upper right, the telescope is focused on a smaller area using Webb’s MIRI (Mid-Infrared Instrument). A total of eighteen filters across both the MIRI and NIRCam instruments were used in these images, covering a range of wavelengths from 1.4 microns in the near-infrared to 25.5 microns in the mid-infrared.
At the very center of the MIRI area is a young star system with a planet-forming disk named d203-506. The pullout at the bottom right displays a combined NIRCam and MIRI image of this young system. Its extended shape is due to pressure from the harsh ultraviolet radiation striking it. An international team of astronomers detected a new carbon molecule known as methyl cation for the first time in d203-506.
ESA/Webb, NASA, CSA, M. Zamani (ESA/Webb), PDRs4ALL ERS Team But stars aren’t the only items visible here. In June 2023, JWST’s NIRCam and MIRI (mid-infrared instrument) imaged a developing star system with a protoplanetary disk forming around it. That’s right – a solar system happening in real time – located within the edges of a section called the Orion Bar. Scientists have named this planet-forming disk d203-506, and you can learn more about the chemistry found here. By capturing these objects in multiple wavelengths of light, astronomers now have even greater insight into what other objects might be hiding within these hazy hydrogen regions of our night sky. This technique is called Multi-spectral Imaging, made possible by numerous new space based telescopes.
In addition to the Night Sky Network Dark Sky Wheel, a fun activity you can share with your astronomy club would be Universe Discovery Guide: Orion Nebula, Nursery of Newborn Stars. This will allow you to explain to audiences how infrared astronomy, like JWST, helps to reveal the secrets of nebulae. Or you can use public projects like the NASA-funded MicroObservatory to capture M42 and other objects.
Stay tuned to learn more about what to spy in the Winter sky with our upcoming mid-month article!

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA completed a full duration, 650-second hot fire of the RS-25 certification engine Nov. 29, continuing a critical test series to support future SLS (Space Launch System) missions to deep space as NASA explores the secrets of the universe for the benefit of all. Danny Nowlin NASA completed a full duration, 650-second hot fire of the RS-25 certification engine Nov. 29, continuing a critical test series to support future SLS (Space Launch System) missions to deep space as NASA explores the secrets of the universe for the benefit of all. Danny Nowlin NASA completed a full duration, 650-second hot fire of the RS-25 certification engine Nov. 29, continuing a critical test series to support future SLS (Space Launch System) missions to deep space as NASA explores the secrets of the universe for the benefit of all. Danny Nowlin NASA conducted the third RS-25 engine hot fire in a critical 12-test certification series Nov. 29, demonstrating a key capability necessary for flight of the SLS (Space Launch System) rocket during Artemis missions to the Moon and beyond.
NASA is conducting the series of tests to certify new manufacturing processes for producing RS-25 engines for future deep space missions, beginning with Artemis V. Aerojet Rocketdyne, an L3Harris Technologies Company and lead engines contractor for the SLS rocket, is incorporating new manufacturing techniques and processes, such as 3D printing, in production of new RS-25 engines.
Crews gimbaled, or pivoted, the RS-25 engine around a central point during the almost 11-minute (650 seconds) hot fire on the Fred Haise Test Stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. The gimbaling technique is used to control and stabilize SLS as it reaches orbit.
During the Nov. 29 test, operators also pushed the engine beyond any parameters it might experience during flight to provide a margin of operational safety. The 650-second test exceeded the 500 seconds RS-25 engines must operate to help power SLS to space. The RS-25 engine also was fired to 113% power level, exceeding the 111% level needed to lift SLS to orbit.
The ongoing series will stretch into 2024 as NASA continues its mission to return humans to the lunar surface to establish a long-term presence for scientific discovery and to prepare for human missions to Mars.
Four RS-25 engines fire simultaneously to generate a combined 1.6 million pounds of thrust at launch and 2 million pounds of thrust during ascent to help power each SLS flight. NASA and Aerojet Rocketdyne modified 16 holdover space shuttle main engines, all proven flightworthy at NASA Stennis, for Artemis missions I through IV.
Every new RS-25 engine that will help power SLS also will be tested at NASA Stennis. RS-25 tests at the site are conducted by a combined team of NASA, Aerojet Rocketdyne, and Syncom Space Services operators. Syncom Space Services is the prime contractor for Stennis facilities and operations.
