Fisher stands in front of the launch vehicle stage adapter for NASA’s SLS (Space Launch System) rocket. The hardware will be used for the agency’s Artemis III mission that will land astronauts on the lunar surface. Fisher works with a number of teams across the agency and believes her background in music education has been an asset to her work as an engineer: “Teaching skills help you look at things from a different perspective and helps with understanding how others might approach a situation – all very helpful when I’m working with teams.”

Not many music majors get to be hands-on with building a Moon rocket, but Lauren Fisher has always enjoyed the unusual.

Now a structural materials engineer at NASA’s Marshall Space Flight Center in Huntsville, Alabama, Fisher works on a key adapter for NASA’s SLS (Space Launch System) rocket for the first crewed missions of NASA’s Artemis campaign.

Manufactured at Marshall by NASA, lead contractor Teledyne Brown Engineering, and the Jacobs Space Exploration Group’s ESSCA contract, the cone-shaped launch vehicle stage adapter partially encloses the rocket’s interim cryogenic propulsion stage and connects it to the core stage below and the Orion stage adapter above. The launch vehicle stage adapter also protects avionics and electrical devices from extreme vibration and acoustic conditions during launch and ascent.

Fisher and the thermal protection system team develop and apply the spray-on foam that acts as insulation and protects the adapter and all its systems from the extreme pressures and temperatures it’ll face during flight. The thermal protection system for the component, unlike other parts of the rocket, is applied by hand using a spray gun. When first applied, the insulation is yellow, but after time and exposure to the Sun, it turns orange.

“We’re taking the same stuff someone might use to insulate their attic, except making it for cryogenic atmospheres, and spraying it all over a giant piece of hardware that will help launch us to the Moon,” Fisher said. “With my work for NASA’s Space Launch System rocket, I get to play with foam and glue. I like to call it arts and crafts engineering!”

Although engineering runs in her family, Fisher initially graduated from University of Southern Mississippi with a Bachelor of Arts in music performance and an interest in music education. She developed an interest in carbon-based polymers, and decided to go back to school, completing a chemical engineering degree with a polymeric materials track from the University of Alabama in Huntsville. Her new degree led to an opportunity to work for the thermal protection system team at Marshall.

When Fisher isn’t in the office, she likes travelling to unusual places and checking items off her self-described “Bizarre Bucket List.” Recently, she went to Punxsutawney, Pennsylvania, to watch the famous groundhog predict an early spring.

Being part of the Artemis Generation is incredibly inspiring for Fisher, who takes pride in her work supporting the first three Artemis missions, including Artemis II, the first crewed mission under Artemis, in 2025.

“I’m literally building the hardware that will send the first woman to deep space,” Fisher says. “Watching our rocket take shape, I’m like ‘you see that thing? I did that; that’s mine. See that one? My team did that one. We did that, and see this?’” She beams with pride. “You can do that, too. Just being a part of the generation that’s changing the workforce and changing the space program — it gives me goosebumps.”

NASA is working to land the first woman, first person of color, and its first international partner astronaut on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft and Gateway in orbit around the Moon and commercial human landing systems, next-generational spacesuits, and rovers on the lunar surface. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.

NASA Images Help Explain Eating Habits of Massive Black Hole

NASA Images Help Explain Eating Habits of Massive Black Hole

4 min read

Preparations for Next Moonwalk Simulations Underway (and Underwater)

Data from NASA’s retired Spitzer Space Telescope has given scientists new insights into why some supermassive black holes shine differently than others.

In images from NASA’s retired Spitzer Space Telescope, streams of dust thousands of light-years long flow toward the supermassive black hole at the heart of the Andromeda galaxy. It turns out these streams can help explain how black holes billions of times the mass of our Sun satiate their big appetites but remain “quiet” eaters.

As supermassive black holes gobble up gas and dust, the material gets heated up just before it falls in, creating incredible light shows — sometimes brighter than an entire galaxy full of stars. When the material is consumed in clumps of different sizes, the brightness of the black hole fluctuates.

But the black holes at the center of the Milky Way (Earth’s home galaxy) and Andromeda (one of our nearest galactic neighbors) are among the quietest eaters in the universe. What little light they emit does not vary significantly in brightness, suggesting they are consuming a small but steady flow of food, rather than large clumps. The streams approach the black hole little by little, and in a spiral, similar to the way the water swirls down a drain.

Hunting for Andromeda’s Food Source

A study published earlier this year took the hypothesis that a quiet supermassive black hole feeds on a steady stream of gas and applied it to the Andromeda galaxy. Using computer models, the authors simulated how gas and dust in proximity to Andromeda’s supermassive black hole might behave over time. The simulation demonstrated that a small disk of hot gas could form close to the supermassive black hole and feed it continuously. The disk could be replenished and maintained by numerous streams of gas and dust.

But the researchers also found that those streams have to stay within a particular size and flow rate; otherwise, the matter would fall into the black hole in irregular clumps, causing more light fluctuation.

This close-up view of the center of the Andromeda galaxy, taken by NASA’s retired Spitzer Space Telescope, is annotated with blue dotted lines to highlight the path of two dust streams flowing toward the supermassive black hole at the galaxy’s center (indicated by a purple dot).

When the authors compared their findings to data from Spitzer and NASA’s Hubble Space Telescope, they found spirals of dust previously identified by Spitzer that fit within these constraints. From this, the authors concluded that the spirals are feeding Andromeda’s supermassive black hole.

“This is a great example of scientists reexamining archival data to reveal more about galaxy dynamics by comparing it to the latest computer simulations,” said Almudena Prieto, an astrophysicist at the Institute of Astrophysics of the Canary Islands and the University Observatory Munich, and a co-author on the study published this year. “We have 20-year-old data telling us things we didn’t recognize in it when we first collected it.”

A Deeper Look at Andromeda

Launched in 2003 and managed by NASA’s Jet Propulsion Laboratory, Spitzer studied the universe in infrared light, which is invisible to human eyes. Different wavelengths reveal different features of Andromeda, including hotter sources of light, like stars, and cooler sources, like dust.

By separating these wavelengths and looking at the dust alone, astronomers can see the galaxy’s “skeleton” — places where gas has coalesced and cooled, sometimes forming dust, creating conditions for stars to form. This view of Andromeda revealed a few surprises. For instance, although it is a spiral galaxy like the Milky Way, Andromeda is dominated by a large dust ring rather than distinct arms circling its center. The images also revealed a secondary hole in one portion of the ring where a dwarf galaxy passed through.

Andromeda’s proximity to the Milky Way means it looks larger than other galaxies from Earth: Seen with the naked eye, Andromeda would be about six times the width of the Moon (about 3 degrees). Even with a field of view wider than Hubble’s, Spitzer had to take 11,000 snapshots to create this comprehensive picture of Andromeda.

More About the Mission

JPL managed the Spitzer Space Telescope mission for NASA’s Science Mission Directorate in Washington until the mission was retired in January 2020. Science operations were conducted at the Spitzer Science Center at Caltech. Spacecraft operations were based at Lockheed Martin Space in Littleton, Colorado. Data are archived at the Infrared Science Archive operated by IPAC at Caltech. Caltech manages JPL for NASA.
