Marshall’s First Woman Director of Engineering Directorate Celebrates Retirement

By Celine Smith

Mary Beth Koelbl, the first woman to serve as director of the Engineering Directorate at NASA’s Marshall Space Flight Center, celebrated her retirement among Marshall team members and family Nov. 2. Koelbl retires after serving 37 years at Marshall.

Marshall Associate Director, Technical, Larry Leopard gave a speech in honor of Koelbl’s impactful career. Both Leopard and Holder stressed how Koelbl’s personable character and great collaborative efforts made her career and teams successful.

“Mary Beth has provided outstanding public service to not only engineering but to the center,” Leopard said. “She has been a standard for everybody to follow.”

Appointed to the position in July 2019, Koelbl helped oversee Marshall’s largest organization, comprised of more than 2,000 civil servants and contractors responsible for the design, testing, evaluation and operation of flight hardware and software associated with space transportation and spacecraft systems, science instruments and payloads now in development at Marshall. The directorate provides critical support to NASA’s SLS (Space Launch System) Program, which is managing the construction and testing of the world’s most powerful rocket.

Don Holder was named new director of engineering after previously serving in the role of deputy director under Koelbl.

“Mary Beth Koelbl’s positive attitude toward people and caring about their development has benefited the organization tremendously,” Holder said.

Prior to this appointment, Koelbl was director of the Propulsion Systems Department from 2015 to 2019. In that position, she also served as NASA’s senior executive overseeing the agency’s chemical propulsion capability, leading work across multiple field centers to effectively develop, mature, and apply chemical propulsion capabilities in support of NASA’s missions.

Throughout her NASA career, Koelbl has supported large, complex propulsion systems development and operations efforts for SLS, NASA’s Commercial Crew Program, and various planetary lander development activities. She also contributed to historic efforts such as the space shuttle main engine technology test bed, the Fastrac 60K engine, all shuttle propulsion elements, the Altair spacecraft, and the Ares launch vehicle upper stage and upper stage engine.

Koelbl joined Marshall in 1986 as an aerospace engineer in the Turbomachinery and Combustion Devices Branch. She was named deputy group lead of the Engineering Directorate’s Engine Systems Engineering Group in 2000 and group leader in 2003. In 2005, following a center wide reorganization, Koelbl was named branch chief of the Engine and Main Propulsion Systems Branch. She was promoted to division chief of the Propulsion Systems Division in 2011, and later that year was named to the Senior Executive Service position of deputy director of the Propulsion Systems Department. The Senior Executive Service is the personnel system covering most of the top managerial positions in federal agencies.

“I have no plans of working after retirement because nothing could be better than this,” Koelbl said in her closing remarks at the reception.

A native of Iowa City, Iowa, Koelbl earned a bachelor’s degree in mechanical engineering in 1985 from the University of Iowa. She has been the recipient of many prestigious awards, including a NASA Exceptional Service Medal in 2018, NASA Leadership Medal in 2007, Space Flight Awareness Award in 2005, and Silver Snoopy in 1996.​​​​​​​

Koelbl and her husband, Terry, who is also a NASA engineer at Marshall, reside in Madison with their three sons. She plans on enjoying her retirement by spending time with her children and grandchildren.

“I’m surely going to miss the people at Marshall – they’re the best,” Koelbl said.

Michoud Celebrates Family Day 2023 with Treats and No Tricks

By Matt Higgins

For the second consecutive year, NASA’s Michoud Assembly Facility hosted Family Day, a day when team members can invite their families to visit “America’s Rocket Factory.”

This year’s Family Day was Oct. 28.

Thousands attend Michoud Family 2023 on Oct. 28 to observe Artemis production, interact with Michoud tenants, and enjoy Halloween festivities.

“Family Day 2023 was a huge success,” said Michoud Director Lonnie Dutreix. “I enjoyed seeing the employees bring their families and seeing the looks of awe and smiling faces all around.”

Family Day occurred the weekend before Halloween. Team members and their families had the opportunity to view the latest stages of production in the 43-acre factory, including the fully assembled core stage for NASA’s SLS (Space Launch System) rocket for NASA’s Artemis II mission, and were treated to trunk-or-treat as they exited the factory. Michoud passed out candy and Moon Pies to trick-or-treaters of all ages. 

“Family Day 2023 was an opportunity to build on last year’s success,” said Heather Keller, Michoud communications strategist and Family Day coordinator. “We even took advantage of the holiday weekend to include a trunk-or-treat for the kids.”

Mother Nature spared the heavy rains that occurred during Family Day 2022. The lack of rain and threatening skies allowed for more displays and attractions. There were food trucks outside the factory gates, and a Coast Guard Sikorsky MH-60 Jayhawk helicopter landed on the facility grounds. Attendees viewed the distinct orange and white helicopter up close, sat inside, and took pictures. NASA astronaut Stan Love and astronaut candidate Jack Hathaway took pictures with families in front of the SLS core stage for Artemis II in the Final Assembly area. 

Michoud’s tenants, including its prime contractors Boeing and Lockheed Martin, set up booths and provided swag for those who passed by. Some tenants included interactive virtual reality displays and science experiments. 

“With the addition of astronauts, a USCG rescue helicopter, food trucks, and emergency and heavy equipment static displays, there really was something for everyone,” Keller said.

Prior to 2022’s celebration, Michoud Family Day hadn’t occurred since before the COVID-19 pandemic, and strong thunderstorms kept many people away in 2022. It meant that this year’s event was the first time many family members had seen Michoud in years and the first for many others. Organizers estimated more than 5,000 attended the event.

For Dutreix, it marked one of the final major events of his tenure. He will retire in December.

“It’s my last Family Day as director,” he said. “I’m going to miss it, but I’m proud of the family atmosphere we have at Michoud. The workforce looks out for each other, and we’re committed to seeing Artemis succeed.”

NASA Telescopes Discover Record-breaking Black Hole

Astronomers have discovered the most distant black hole yet seen in X-rays, using NASA telescopes. The black hole is at an early stage of growth that had never been witnessed before, where its mass is similar to that of its host galaxy.

This result may explain how some of the first supermassive black holes in the universe formed.

By combining data from NASA’s Chandra X-ray Observatory and NASA’s James Webb Space Telescope, a team of researchers was able to find the telltale signature of a growing black hole just 470 million years after the big bang.

Astronomers found the most distant black hole ever detected in X-rays (in a galaxy dubbed UHZ1) using the Chandra and Webb space telescopes. X-ray emission is a telltale signature of a growing supermassive black hole. This result may explain how some of the first supermassive black holes in the universe formed. This image shows the galaxy cluster Abell 2744 that UHZ1 is located behind, in X-rays from Chandra and infrared data from Webb, as well as close-ups of the black hole host galaxy UHZ1.

“We needed Webb to find this remarkably distant galaxy and Chandra to find its supermassive black hole,” said Akos Bogdan of the Center for Astrophysics | Harvard & Smithsonian (CfA) who leads a new paper in the journal Nature Astronomy describing these results. “We also took advantage of a cosmic magnifying glass that boosted the amount of light we detected.” This magnifying effect is known as gravitational lensing.

Bogdan and his team found the black hole in a galaxy named UHZ1 in the direction of the galaxy cluster Abell 2744, located 3.5 billion light-years from Earth. Webb data, however, has revealed the galaxy is much more distant than the cluster, at 13.2 billion light-years from Earth, when the universe was only 3% of its current age.

Then over two weeks of observations with Chandra showed the presence of intense, superheated, X-ray emitting gas in this galaxy – a trademark for a growing supermassive black hole. The light from the galaxy and the X-rays from gas around its supermassive black hole are magnified by about a factor of four by intervening matter in Abell 2744 (due to gravitational lensing), enhancing the infrared signal detected by Webb and allowing Chandra to detect the faint X-ray source.

This discovery is important for understanding how some supermassive black holes can reach colossal masses soon after the big bang. Do they form directly from the collapse of massive clouds of gas, creating black holes weighing between about 10,000 and 100,000 Suns? Or do they come from explosions of the first stars that create black holes weighing only between about 10 and 100 Suns?

“There are physical limits on how quickly black holes can grow once they’ve formed, but ones that are born more massive have a head start. It’s like planting a sapling, which takes less time to grow into a full-size tree than if you started with only a seed”, said Andy Goulding of Princeton University. Goulding is a co-author of the Nature Astronomy paper and lead author of a new paper in The Astrophysical Journal Letters that reports the galaxy’s distance and mass using a spectrum from Webb.

Bogdan’s team has found strong evidence that the newly discovered black hole was born massive. Its mass is estimated to fall between 10 and 100 million Suns, based on the brightness and energy of the X-rays. This mass range is similar to that of all the stars in the galaxy where it lives, which is in stark contrast to black holes in the centers of galaxies in the nearby universe that usually contain only about a tenth of a percent of the mass of their host galaxy’s stars.

The large mass of the black hole at a young age, plus the amount of X-rays it produces and the brightness of the galaxy detected by Webb, all agree with theoretical predictions in 2017 by co-author Priyamvada Natarajan of Yale University for an “Outsize Black Hole” that directly formed from the collapse of a huge cloud of gas.

“We think that this is the first detection of an ‘Outsize Black Hole’ and the best evidence yet obtained that some black holes form from massive clouds of gas,” said Natarajan. “For the first time we are seeing a brief stage where a supermassive black hole weighs about as much as the stars in its galaxy, before it falls behind.”

The researchers plan to use this and other results pouring in from Webb and those combining data from other telescopes to fill out a larger picture of the early universe.

NASA’s Hubble Space Telescope previously showed that light from distant galaxies is highly magnified by matter in the intervening galaxy cluster, providing part of the motivation for the Webb and Chandra observations described here.

The paper describing the results by Bogdan’s team appears in Nature Astronomy, and a preprint is available online.

The Webb data used in both papers is part of a survey called the Ultradeep Nirspec and nirCam ObserVations before the Epoch of Reionization (UNCOVER). The paper led by UNCOVER team member Andy Goulding appears in the Astrophysical Journal Letters. The co-authors include other UNCOVER team members, plus Bogdan and Natarajan. A detailed interpretation paper that compares observed properties of UHZ1 with theoretical models for Outsize Black Hole Galaxies is forthcoming.

NASA’s Marshall Space Flight Center manages the Chandra program. The Smithsonian Astrophysical Observatory’s Chandra X-ray Center controls science operations from Cambridge, Massachusetts, and flight operations from Burlington, Massachusetts.

The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency.

Lucy Discovery Highlighted on ‘This Week at NASA’

NASA’s Lucy spacecraft got a surprise when it flew by asteroid Dinkinesh on Nov. 1 – the first of multiple asteroids Lucy will visit on its 12-year voyage. The mission is featured in “This Week @ NASA,” a weekly video program broadcast on NASA-TV and posted online.

Images captured by Lucy revealed that Dinkinesh is not just a single asteroid, as was thought, but a binary pair. The primary aim of the Lucy mission is to survey the Jupiter Trojan asteroids, a never-before-explored population of small bodies that orbit the Sun in two “swarms” that lead and follow Jupiter in its orbit.

NASA’s Goddard Space Flight Center provides overall mission management, systems engineering, and safety and mission assurance. Lockheed Martin Space in Littleton, Colorado, built the spacecraft. Lucy is the 13th mission in NASA’s Discovery Program. NASA’s Marshall Space Flight Center manages the Discovery Program for the Science Mission Directorate at NASA Headquarters.

      Webb captured this sparkling scene of star birth in Pismis 24. Full image and caption below. Credits:
      Image: NASA, ESA, CSA, STScI; Image Processing: A. Pagan (STScI) This is a sparkling scene of star birth captured by NASA’s James Webb Space Telescope. What appears to be a craggy, starlit mountaintop kissed by wispy clouds is actually a cosmic dust-scape being eaten away by the blistering winds and radiation of nearby, massive, infant stars.
      Called Pismis 24, this young star cluster resides in the core of the nearby Lobster Nebula, approximately 5,500 light-years from Earth in the constellation Scorpius. Home to a vibrant stellar nursery and one of the closest sites of massive star birth, Pismis 24 provides rare insight into large and massive stars. Its proximity makes this region one of the best places to explore the properties of hot young stars and how they evolve.
      At the heart of this glittering cluster is the brilliant Pismis 24-1. It is at the center of a clump of stars above the jagged orange peaks, and the tallest spire is pointing directly toward it. Pismis 24-1 appears as a gigantic single star, and it was once thought to be the most massive known star. Scientists have since learned that it is composed of at least two stars, though they cannot be resolved in this image. At 74 and 66 solar masses, respectively, the two known stars are still among the most massive and luminous stars ever seen.
      Image A: Pismis 24 (NIRCam Image)
      Webb captured this sparkling scene of star birth in Pismis 24, a young star cluster about 5,500 light-years from Earth in the constellation Scorpius. This region is one of the best places to explore the properties of hot young stars and how they evolve. Image: NASA, ESA, CSA, STScI; Image Processing: A. Pagan (STScI) Captured in infrared light by Webb’s NIRCam (Near-Infrared Camera), this image reveals thousands of jewel-like stars of varying sizes and colors. The largest and most brilliant ones with the six-point diffraction spikes are the most massive stars in the cluster. Hundreds to thousands of smaller members of the cluster appear as white, yellow, and red, depending on their stellar type and the amount of dust enshrouding them. Webb also shows us tens of thousands of stars behind the cluster that are part of the Milky Way galaxy.
      Super-hot, infant stars –some almost 8 times the temperature of the Sun – blast out scorching radiation and punishing winds that are sculpting a cavity into the wall of the star-forming nebula. That nebula extends far beyond NIRCam’s field of view. Only small portions of it are visible at the bottom and top right of the image. Streamers of hot, ionized gas flow off the ridges of the nebula, and wispy veils of gas and dust, illuminated by starlight, float around its towering peaks.
      Dramatic spires jut from the glowing wall of gas, resisting the relentless radiation and winds. They are like fingers pointing toward the hot, young stars that have sculpted them. The fierce forces shaping and compressing these spires cause new stars to form within them. The tallest spire spans about 5.4 light-years from its tip to the bottom of the image. More than 200 of our solar systems out to Neptune’s orbit could fit into the width its tip, which is 0.14 lightyears.
      In this image, the color cyan indicates hot or ionized hydrogen gas being heated up by the massive young stars. Dust molecules similar to smoke here on Earth are represented in orange. Red signifies cooler, denser molecular hydrogen. The darker the red, the denser the gas. Black denotes the densest gas, which is not emitting light. The wispy white features are dust and gas that are scattering starlight.

      Hubble Homes in on Galaxy’s Star Formation
      This NASA/ESA Hubble Space Telescope image features the asymmetric spiral galaxy Messier 96. ESA/Hubble & NASA, F. Belfiore, D. Calzetti This NASA/ESA Hubble Space Telescope image features a galaxy whose asymmetric appearance may be the result of a galactic tug of war. Located 35 million light-years away in the constellation Leo, the spiral galaxy Messier 96 is the brightest of the galaxies in its group. The gravitational pull of its galactic neighbors may be responsible for Messier 96’s uneven distribution of gas and dust, asymmetric spiral arms, and off-center galactic core.
      This asymmetric appearance is on full display in the new Hubble image that incorporates data from observations made in ultraviolet, near infrared, and visible/optical light. Earlier Hubble images of Messier 96 were released in 2015 and 2018. Each successive image added new data, building up a beautiful and scientifically valuable view of the galaxy.
      The 2015 image combined two wavelengths of optical light with one near infrared wavelength. The optical light revealed the galaxy’s uneven form of dust and gas spread asymmetrically throughout its weak spiral arms and its off-center core, while the infrared light revealed the heat of stars forming in clouds shaded pink in the image.
      The 2018 image added two more optical wavelengths of light along with one wavelength of ultraviolet light that pinpointed areas where high-energy, young stars are forming.
      This latest version offers us a new perspective on Messier 96’s star formation. It includes the addition of light that reveals regions of ionized hydrogen (H-alpha) and nitrogen (NII). This data helps astronomers determine the environment within the galaxy and the conditions in which stars are forming. The ionized hydrogen traces ongoing star formation, revealing regions where hot, young stars are ionizing the gas. The ionized nitrogen helps astronomers determine the rate of star formation and the properties of gas between stars, while the combination of the two ionized gasses helps researchers determine if the galaxy is a starburst galaxy or one with an active galactic nucleus.
      The bubbles of pink gas in this image surround hot, young, massive stars, illuminating a ring of star formation in the galaxy’s outskirts. These young stars are still embedded within the clouds of gas from which they were born. Astronomers will use the new data in this image to study how stars are form within giant dusty gas clouds, how dust filters starlight, and how stars affect their environments.

      This graphic features data from NASA’s Chandra X-ray Observatory of the Cassiopeia A (Cas A) supernova remnant that reveals that the star’s interior violently rearranged itself mere hours before it exploded. The main panel of this graphic is Chandra data that shows the location of different elements in the remains of the explosion: silicon (represented in red), sulfur (yellow), calcium (green) and iron (purple). The blue color reveals the highest-energy X-ray emission detected by Chandra in Cas A and an expanding blast wave. The inset reveals regions with wide ranges of relative abundances of silicon and neon. This data, plus computer modeling, reveal new insight into how massive stars like Cas A end their lives.X-ray: NASA/CXC/Meiji Univ./T. Sato et al.; Image Processing: NASA/CXC/SAO/N. Wolk The inside of a star turned on itself before it spectacularly exploded, according to a new study from NASA’s Chandra X-ray Observatory. Today, this shattered star, known as the Cassiopeia A supernova remnant, is one of the best-known, well-studied objects in the sky.
      Over three hundred years ago, however, it was a giant star on the brink of self-destruction. The new Chandra study reveals that just hours before it exploded, the star’s interior violently rearranged itself. This last-minute shuffling of its stellar belly has profound implications for understanding how massive stars explode and how their remains behave afterwards.
      Cassiopeia A (Cas A for short) was one of the first objects the telescope looked at after its launch in 1999, and astronomers have repeatedly returned to observe it.
      “It seems like each time we closely look at Chandra data of Cas A, we learn something new and exciting,” said Toshiki Sato of Meiji University in Japan who led the study. “Now we’ve taken that invaluable X-ray data, combined it with powerful computer models, and found something extraordinary.”
      As massive stars age, increasingly heavy elements form in their interiors by nuclear reactions, creating onion-like layers of different elements. Their outer layer is mostly made of hydrogen, followed by layers of helium, carbon and progressively heavier elements – extending all the way down to the center of the star. 
      Once iron starts forming in the core of the star, the game changes. As soon as the iron core grows beyond a certain mass (about 1.4 times the mass of the Sun), it can no longer support its own weight and collapses. The outer part of the star falls onto the collapsing core, and rebounds as a core-collapse supernova.
      The new research with Chandra data reveals a change that happened deep within the star at the very last moments of its life. After more than a million years, Cas A underwent major changes in its final hours before exploding.
      “Our research shows that just before the star in Cas A collapsed, part of an inner layer with large amounts of silicon traveled outwards and broke into a neighboring layer with lots of neon,” said co-author Kai Matsunaga of Kyoto University in Japan. “This is a violent event where the barrier between these two layers disappears.”
      This upheaval not only caused material rich in silicon to travel outwards; it also forced material rich in neon to travel inwards. The team found clear traces of these outward silicon flows and inward neon flows in the remains of Cas A’s supernova remnant. Small regions rich in silicon but poor in neon are located near regions rich in neon and poor in silicon. 
      The survival of these regions not only provides critical evidence for the star’s upheaval, but also shows that complete mixing of the silicon and neon with other elements did not occur immediately before or after the explosion. This lack of mixing is predicted by detailed computer models of massive stars near the ends of their lives.
      There are several significant implications for this inner turmoil inside of the doomed star. First, it may directly explain the lopsided rather than symmetrical shape of the Cas A remnant in three dimensions. Second, a lopsided explosion and debris field may have given a powerful kick to the remaining core of the star, now a neutron star, explaining the high observed speed of this object.
      Finally, the strong turbulent flows created by the star’s internal changes may have promoted the development of the supernova blast wave, facilitating the star’s explosion.
      “Perhaps the most important effect of this change in the star’s structure is that it may have helped trigger the explosion itself,” said co-author Hiroyuki Uchida, also of Kyoto University. “Such final internal activity of a star may change its fate—whether it will shine as a supernova or not.”
      These results have been published in the latest issue of The Astrophysical Journal and are available online.

      Visual Description
      This release features a composite image of Cassiopeia A, a donut-shaped supernova remnant located about 11,000 light-years from Earth. Included in the image is an inset closeup, which highlights a region with relative abundances of silicon and neon.
      Over three hundred years ago, Cassiopeia A, or Cas A, was a star on the brink of self-destruction. In composition it resembled an onion with layers rich in different elements such as hydrogen, helium, carbon, silicon, sulfur, calcium, and neon, wrapped around an iron core. When that iron core grew beyond a certain mass, the star could no longer support its own weight. The outer layers fell into the collapsing core, then rebounded as a supernova. This explosion created the donut-like shape shown in the composite image. The shape is somewhat irregular, with the thinner quadrant of the donut to the upper left of the off-center hole.
      In the body of the donut, the remains of the star’s elements create a mottled cloud of colors, marbled with red and blue veins. Here, sulfur is represented by yellow, calcium by green, and iron by purple. The red veins are silicon, and the blue veins, which also line the outer edge of the donut-shape, are the highest energy X-rays detected by Chandra and show the explosion’s blast wave.
      The inset uses a different color code and highlights a colorful, mottled region at the thinner, upper left quadrant of Cas A. Here, rich pockets of silicon and neon are identified in the red and blue veins, respectively. New evidence from Chandra indicates that in the hours before the star’s collapse, part of a silicon-rich layer traveled outwards, and broke into a neighboring neon-rich layer. This violent breakdown of layers created strong turbulent flows and may have promoted the development of the supernova’s blast wave, facilitating the star’s explosion. Additionally, upheaval in the interior of the star may have produced a lopsided explosion, resulting in the irregular shape, with an off-center hole (and a thinner bite of donut!) at our upper left.

      NASA’s 1991 Discovery shuttle video shows UFOs making impossible maneuvers, evading a possible Star Wars railgun test. Evidence of secret tech? 

      In September 1991, NASA’s Space Shuttle Discovery transmitted live video that has since become one of the most debated UFO clips ever recorded. The footage, later analyzed by independent researchers, shows glowing objects in orbit performing maneuvers far beyond the limits of known physics. 
      One object appears over Earth’s horizon, drifts smoothly, then suddenly reacts to a flash of light by accelerating at impossible speeds, estimated at over 200,000 mph while withstanding forces of 14,000 g’s. NASA officially dismissed the anomalies as ice particles or debris, but side by side comparisons with actual orbital ice show key differences: the objects make sharp turns, sudden accelerations, and fade in brightness in ways consistent with being hundreds of miles away, not near the shuttle. 
      Image analysis expert Dr. Mark Carlotto confirmed that at least one object was located about 1,700 miles from the shuttle, placing it in Earth’s atmosphere. At that distance, the object would be too large and too fast to be dismissed as ice or space junk. 
      The flash and two streaks seen in the video resemble the Pentagon’s “Brilliant Pebbles” concept, a railgun based missile defense system tested in the early 1990s. Researchers suggest the shuttle cameras may have accidentally, or deliberately, captured a live Star Wars weapons test in orbit. 
      The UFO easily evaded the attack, leading some to conclude that it was powered by a form of hyperdimensional technology capable of altering gravity. 
      Notably, following this 1991 incident, all subsequent NASA shuttle external camera feeds were censored or delayed, raising speculation that someone inside the agency allowed the extraordinary footage to slip out.
