Agency Leadership Talks NASA 2040, Artemis, Budget at Marshall Town Hall

By Jessica Barnett

From funding to historic achievements to the future of NASA, there was no shortage of topics for discussion during the latest Marshall Town Hall.

Marshall team members joined in person and online as Acting Marshall Center Director Joseph Pelfrey, NASA Administrator Bill Nelson, Deputy Administrator Pam Melroy, Associate Administrator Bob Cabana, and Deputy Associate Administrator Casey Swails shared their goals for Marshall and the agency’s future and answered questions from the audience in Activities Building 4316 on Sept. 18.

Pelfrey kicked off the town hall by welcoming agency leaders and showering praise on the Marshall team.

“It’s exciting to see the accomplishments of what we’re doing as an agency and see so many parts of that have a Marshall fingerprint,” Pelfrey said. “It’s an honor to have our leadership team here to share some of the things going on within our agency and how Marshall fits into those plans.”

Nelson followed Pelfrey’s speech with another round of praise, calling Marshall team members “wizards who make the impossible possible.”

“We’re going back to the Moon to learn, to live, to create, to invent, in order for us to go to Mars and beyond, to discover those far, distant cosmic shores,” Nelson said. “And Marshall is very much a part of this.”

That work is being supported in part by NASA 2040, a strategic agency initiative aimed at driving meaningful changes that will allow the agency to realize its long-term vision for what leaders want the agency to be in 2040.

“Personally, I think it’s NASA’s role to do really hard things that only NASA can do,” Swails said. “When we talk about 2040 and we talk about our mission strategy, how we do make sure we have an operating model that best sets us up for a future that aligns to mission goals? How do we make sure we have an institution that frankly reflects how amazing and incredible our mission is?”

Swails then presented the plan to achieving those goals which included a seven-part list of workstreams with associated teams and leaders focused on supporting the workforce, infrastructure, and technologies critical to keeping NASA a leader in science, aeronautics, and space exploration.

In addition to her speech, Swails held meetings Sept. 22 to further discuss NASA 2040. Cabana stressed the importance of such meetings and listening sessions during his portion of the town hall, encouraging Marshall team members to seize the opportunity to attend and offer feedback.

Agency leaders also shared how Marshall is key to not just the initiative’s success but the success of NASA’s mission.

“It’s important that we articulate and emphasize the science, technology, and impact we have,” Melroy said. “I’m personally excited, as I see the incredible science you work on here with ISS, what new discoveries we’re going to get with Artemis.”

Melroy and Cabana noted Marshall’s work on nuclear propulsion, with Artemis, and with the International Space Station.

“You’re not making a difference for Marshall Space Flight Center, the state of Alabama, or even the United States,” Cabana said. “You’re making a difference for humanity.”

Cabana provided an update on the Artemis program, telling audience members that Artemis II is still on track for its launch next year and work is underway to prepare for Artemis III’s launch in 2025. He encouraged Marshall team members to be active participants and promote an inclusive environment as the agency continues toward 2040.

“What we are doing is too critical not to give it our very best and have that environment,” he said.

Also critical, however, is ensuring NASA has the budget for its goals. Nelson, a former U.S. senator, said he isn’t sure what those currently in Congress will decide, but he remains confident that NASA will be just fine.

He said there’s talk of NASA receiving level funding, which has caused angst among some, but that NASA’s international reach has made it favorable on both sides of the political aisle.

“At the end of the day, it’s going to be all right,” Nelson said. “There will be some bumps along the way on this budget; it is a sign of the times. I wish it were not that way, but I can tell you that NASA brings people together, and NASA unites, not just in domestic politics but around the world as well.”

Marshall Wins Award for Most Funds Raised During 2022 Combined Federal Campaign

By Jessica Barnett

NASA’s Marshall Space Flight Center was recently awarded for raising more funds than any other large federal agency in the Greater Tennessee Valley Zone during the 2022 CFC (Combined Federal Campaign).

The CFC serves as the federal government’s only sanctioned charity fundraiser event, with civilian, military, contract, and postal employees all encouraged to contribute to the charity of their choice during the annual campaign.

Marshall kicked off the 2022 campaign last October with a charity fair, giving potential donors a chance to learn about some of the charities that benefit from CFC donations.  Erin Richardson, a materials science manager at Marshall who served as chair of the 2022 campaign, said the goal was more than just raising funds – it was about raising awareness of CFC and increasing participation in the campaign.

“We ended up contributing the most out of any large agency in the Greater Tennessee Valley, which is our CFC zone,” Richardson said, adding the win came as a surprise given some of the obstacles they faced.

Those obstacles included inflation and economic concerns among potential donors, balancing virtual and in-person campaigning after the pandemic, and it being the first time Richardson and many of her co-campaigners had served as CFC leaders at Marshall.

Looking back on it now, she said, there were certainly some lessons learned. Richardson said she’s optimistic for the 2023 campaign, which will be chaired by Angela Lovelady, a lead budget analyst at Marshall.

“Angela is a step above,” Richardson said. “She has an intense passion and heart for it, and I think she’ll be a great lead for CFC.”

Marshall team members raised more funds than any other large federal agency in the Greater Tennessee Valley Zone during the 2022 Combined Federal Campaign. Overseen by the Office of Personnel Management, CFC is the official workplace giving campaign for federal employees, contractors, and retirees.

Marshall team members who wish to match that enthusiasm will have plenty of ways to do so when the 2023 campaign kicks off Oct. 17. Donors can contribute financially via credit or debit card payment or PayPal, with some team members able to donate a portion of their paycheck during the campaign period. Donors can also contribute their time at a participating charity, with each volunteer hour counted toward the overall fundraising goal.

All campaigns start after Sept. 1 and end before mid-January of the following year. Each donation must be designated for a specific participating charity. In the Greater Tennessee Valley Zone, there are 69 charities currently listed as active CFC participants, from community health clinics and animal rescues to veteran and social justice groups.

By participating in CFC each year, Marshall can show its support to the people all over the world, including the millions of U.S. taxpayers who make NASA’s mission possible, Richardson said.

“We benefit so much as federal employees from taxpayers,” she said. “Some people will never get the opportunity to come through Gate 9 or see a launch or understand what we do, but we wouldn’t be able to do the job we are doing without them.”

Start Your Engines: NASA to Begin Critical Testing for Future Artemis Missions

NASA will begin a new RS-25 test series Oct. 5, the final round of certification testing ahead of production of an updated set of the engines for the SLS (Space Launch System) rocket. The engines will help power future Artemis missions to the Moon and beyond.

A series of 12 tests stretching into 2024 is scheduled to occur on the Fred Haise Test Stand at NASA’s Stennis Space Center. The tests are a key step for lead SLS engines contractor Aerojet Rocketdyne, an L3Harris Technologies company, to produce engines that will help power the SLS rocket, beginning with Artemis V.

“NASA and our industry partners continue to make steady progress toward restarting production of the RS-25 engines for the first time since the space shuttle era as we prepare for our more ambitious missions to deep space under Artemis with the SLS rocket,” said Johnny Heflin, liquid engines manager for SLS at NASA’s Marshall Space Flight Center. “The upcoming fall test series builds off previous hot fire testing already conducted at NASA Stennis to help certify a new design that will make this storied spaceflight engine even more powerful.”

For each Artemis mission, four RS-25 engines, along with a pair of solid rocket boosters, power the SLS rocket, producing more than 8.8 million pounds of thrust at liftoff. Following a “test like you fly” approach, all 12 tests in the new series are scheduled for at least 500 seconds, the same amount of time the engines must fire during an actual launch.

The 12-test series will use developmental engine E0525 to collect data for the final RS-25 design certification review. The engine features a second set of new key components, including a nozzle, hydraulic actuators, flex ducts, and turbopumps. The components match design features of those used during the initial certification test series completed at the south Mississippi site in June.

“Testing a second set of hardware during this next phase of our certification test series will give us repeatability to ensure we have sound processes for building our new engines,” said Mike Lauer, RS-25 deputy program manager at Aerojet Rocketdyne. “The successful testing of the brand-new certification engine proved our engineering was sound – that the new design is capable of meeting requirements at operating extremes and durations. This next test series will help confirm our manufacturing processes will reliably create production engines that will meet these same requirements.”

Operators will fire the engine at power levels varying between 80% and 113% to test performance in multiple scenarios. The first four Artemis missions are using modified space shuttle main engines that can power up to 109% of their rated level. New RS-25 engines will power up to the 111% level to provide additional thrust. Testing up to the 113% power level provides a margin of operational safety.

The longest test of the new series is planned for 650 seconds. Crews will conduct a gimbal test of the engine to ensure it can pivot as needed to help SLS maintain stability and trajectory during flight. The Oct. 5 test is scheduled for 550 seconds and will fire the RS-25 engine up to 111% power level.

Overall, a total of 6,350 seconds of hot fire is planned for the series. With completion of the campaign, it is anticipated all systems will be “go” to produce 24 new RS-25 engines using the updated design for missions beginning with Artemis V.

“Testing at the historic Fred Haise Test Stand is critical to ensure that our astronauts fly safely,” said Chip Ellis, project manager for RS-25 testing at NASA Stennis. “The test team takes great care to ensure these engines will operate as designed to launch NASA payloads and astronauts to the Moon and beyond.”

Through Artemis, NASA will use innovative technologies and collaborate with commercial and international partners to explore more of the Moon than ever. The agency will use what is learned on and around the Moon to take the next giant leap of sending the first astronauts to Mars.

Chandra Rewinds Story of Great Eruption of the 1840s

A new movie made from over two decades of data from NASA’s Chandra X-ray Observatory shows a famous star system changing with time. Eta Carinae contains two massive stars (one is about 90 times the mass of the Sun and the other is believed to be about 30 times the Sun’s mass).

In the middle of the 19th century, skywatchers observed as Eta Carinae experienced a huge explosion that was dubbed the “Great Eruption.” During this event, Eta Carinae ejected between 10 and 45 times the mass of the Sun. This material became a dense pair of spherical clouds of gas, now called the Homunculus nebula, on opposite sides of the two stars. The Homunculus is clearly seen in a composite image of the Chandra data with optical light from the Hubble Space Telescope (blue, purple, and white).

A faint X-ray shell of the Eta Carinae system is highlighted in this graphic showing the summed image. The image on the left emphasizes the bright X-ray ring, and the image on the right shows the same data but emphasizing the faintest X-rays.
A summed image generated by adding data together reveal important hints about Eta Carinae’s volatile history. This includes the rapid expansion of the ring, and a previously unknown faint shell of X-rays outside it. The image on the left emphasizes the bright X-ray ring, and the image on the right shows the same data but emphasizing the faintest X-rays.
(NASA/SAO/GSFC/M. Corcoran et al.)

A new time-lapse sequence contains frames of Eta Carinae taken with Chandra from 1999, 2003, 2009, 2014, and 2020. Astronomers used the Chandra observations along with data from ESA’s XMM-Newton to watch as the stellar eruption from about 180 years ago continues to expand into space at speeds up to 4.5 million miles per hour. The two massive stars produce the blue, relatively high energy X-ray source in the center of the ring. They are too close to each other to be seen individually.

A bright ring of X-rays (orange) around the Homunculus nebula was discovered about 50 years ago and studied in previous Chandra work. The new movie of Chandra, plus a deep, summed image generated by adding the data together, reveal important hints about Eta Carinae’s volatile history. This includes the rapid expansion of the ring, and a previously unknown faint shell of X-rays outside it.

This faint X-ray shell is highlighted in an additional graphic showing the summed image. The image on the left emphasizes the bright X-ray ring, and the image on the right shows the same data but emphasizing the faintest X-rays. The shell is located in between the two contour levels, as labeled.

Because the newly discovered outer X-ray shell has a similar shape and orientation to the Homunculus nebula, researchers concluded both structures have a common origin. The idea is that material was blasted away from Eta Carinae well before the 1843 Great Eruption – sometime between 1200 and 1800, based on the motion of clumps of gas previously seen in Hubble Space Telescope data. Later this slower material was lit up in X-rays when the fast blast wave from the Great Eruption tore through space, colliding with and heating the material to millions of degrees to create the bright X-ray ring. The blast wave has now traveled beyond the bright ring.

A paper describing these results appeared in The Astrophysical Journal. The authors of the paper are Michael Corcoran (NASA’s Goddard Space Flight Center), Kenji Hamaguchi (GSFC), Nathan Smith (University of Arizona), Ian Stevens (University of Birmingham, UK), Anthony Moffat (University of Montreal), Noel Richardson (Embry-Riddle Aeronautical University), Gerd Weigelt (Max Planck Institute for Radio Astronomy), David Espinoza-Galeas (The Catholic University of America), Augusto Damineli (University of Sao Paolo, Brazil), and Christopher Russell (Catholic University).

New Horizons to Continue Exploring Outer Solar System

NASA has announced an updated plan to continue New Horizons’ mission of exploration of the outer solar system. 

Beginning in fiscal year 2025, New Horizons will focus on gathering unique heliophysics data, which can be readily obtained during an extended, low-activity mode of operations. 

While the science community is not currently aware of any reachable Kuiper Belt object, this new path allows for the possibility of using the spacecraft for a future close flyby of such an object, should one be identified. It also will enable the spacecraft to preserve fuel and reduce operational complexity while a search is conducted for a compelling flyby candidate. 

New Horizons in space
Launched on Jan. 18, 2006, NASA’s New Horizons spacecraft has helped scientists understand worlds at the edge of our solar system by visiting the dwarf planet Pluto (its primary mission) and other observations.

“The New Horizons mission has a unique position in our solar system to answer important questions about our heliosphere and provide extraordinary opportunities for multidisciplinary science for NASA and the scientific community,” said Nicola Fox, associate administrator for NASA’s Science Mission Directorate. “The agency decided that it was best to extend operations for New Horizons until the spacecraft exits the Kuiper Belt, which is expected in 2028 through 2029.” 

This new, extended mission will be primarily funded by NASA’s Planetary Science Division and jointly managed by NASA’s Heliophysics and Planetary Science Divisions.

NASA will assess the budget impact of continuing the New Horizons mission so far beyond its original plan of exploration. As a starting point, funding within the New Frontiers program (including science research and data analysis) will be rebalanced to accommodate extended New Horizons operations, and future projects may be impacted.

Launched on Jan. 18, 2006, NASA’s New Horizons spacecraft has helped scientists understand worlds at the edge of our solar system by visiting the dwarf planet Pluto (its primary mission) and then venturing farther out for a flyby of the Kuiper belt object Arrokoth, a double-lobed relic of the formation of our solar system, and other more remote observations of similar bodies.  

The Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, designed, built, and operates the New Horizons spacecraft, and manages the mission for NASA’s Science Mission Directorate. NASA’s Marshall Space Flight Center Planetary Management Office provides agency oversight for the New Horizons. Southwest Research Institute, based in San Antonio, directs the mission via Principal Investigator Stern, and leads the science team, payload operations and encounter science planning. New Horizons is part of the New Frontiers Program managed by Marshall.

      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.

      NASA’s Chandra Reveals Star’s Inner Conflict Before Explosion
      By NASA
      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 shuttle video shows UFO dodging “Star Wars” Weapons test
      By USH
      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.
