Webb’s study of the second-brightest gamma-ray burst ever seen reveals tellurium.

A team of scientists has used multiple space and ground-based telescopes, including NASA’s James Webb Space Telescope, NASA’s Fermi Gamma-ray Space Telescope, and NASA’s Neil Gehrels Swift Observatory, to observe an exceptionally bright gamma-ray burst, GRB 230307A, and identify the neutron star merger that generated an explosion that created the burst. Webb also helped scientists detect the chemical element tellurium in the explosion’s aftermath.

Bright galaxies and other light sources in various sizes and shapes are scattered across a black swath of space: small points, hazy elliptical-like smudges with halos, and spiral-shaped blobs. The objects vary in color: white, blue-white, yellow-white, and orange-red. Toward the center right is a blue-white spiral galaxy seen face-on that is larger than the other light sources in the image. The galaxy is labeled “former home galaxy.” Toward the upper left is a small red point, which has a white circle around it and is labeled “GRB 230307A kilonova.”
This image from NASA’s James Webb Space Telescope NIRCam (Near-Infrared Camera) instrument highlights Gamma-Ray Burst (GRB) 230307A and its associated kilonova, as well as its former home galaxy, among their local environment of other galaxies and foreground stars. The GRB likely was powered by the merger of two neutron stars. The neutron stars were kicked out of their home galaxy and traveled the distance of about 120,000 light-years, approximately the diameter of the Milky Way galaxy, before finally merging several hundred million years later.

Other elements near tellurium on the periodic table – like iodine, which is needed for much of life on Earth – are also likely to be present among the kilonova’s ejected material. A kilonova is an explosion produced by a neutron star merging with either a black hole or with another neutron star.

“Just over 150 years since Dmitri Mendeleev wrote down the periodic table of elements, we are now finally in the position to start filling in those last blanks of understanding where everything was made, thanks to Webb,” said Andrew Levan of Radboud University in the Netherlands and the University of Warwick in the UK, lead author of the study.

While neutron star mergers have long been theorized as being the ideal “pressure cookers” to create some of the rarer elements substantially heavier than iron, astronomers have previously encountered a few obstacles in obtaining solid evidence.

Long Gamma-Ray Burst

Kilonovae are extremely rare, making it difficult to observe these events. Short gamma-ray bursts (GRBs), traditionally thought to be those that last less than two seconds, can be byproducts of these infrequent merger episodes. (In contrast, long gamma-ray bursts may last several minutes and are usually associated with the explosive death of a massive star.)

The case of GRB 230307A is particularly remarkable. First detected by Fermi in March, it is the second brightest GRB observed in over 50 years of observations, about 1,000 times brighter than a typical gamma-ray burst that Fermi observes. It also lasted for 200 seconds, placing it firmly in the category of long duration gamma-ray bursts, despite its different origin.

“This burst is way into the long category. It’s not near the border. But it seems to be coming from a merging neutron star,” added Eric Burns, a co-author of the paper and member of the Fermi team at Louisiana State University.

Opportunity: Telescope Collaboration

The collaboration of many telescopes on the ground and in space allowed scientists to piece together a wealth of information about this event as soon as the burst was first detected. It is an example of how satellites and telescopes work together to witness changes in the universe as they unfold. 

After the first detection, an intensive series of observations from the ground and from space, including with Swift, swung into action to pinpoint the source on the sky and track how its brightness changed. These observations in the gamma-ray, X-ray, optical, infrared, and radio showed that the optical/infrared counterpart was faint, evolved quickly, and became very red – the hallmarks of a kilonova.

“This type of explosion is very rapid, with the material in the explosion also expanding swiftly,” said Om Sharan Salafia, a co-author of the study at the INAF – Brera Astronomical Observatory in Italy. “As the whole cloud expands, the material cools off quickly and the peak of its light becomes visible in infrared, and becomes redder on timescales of days to weeks.”

Bright galaxies and other light sources in various sizes and shapes are scattered across a black swath of space: small points, hazy elliptical-like smudges with halos, and spiral-shaped blobs. The objects vary in color: white, blue-white, yellow-white, and orange-red. Toward the center right is a blue-white spiral galaxy seen face-on that is larger than the other light sources in the image. The galaxy is labeled “former home galaxy.” Toward the upper left is a small red point, which has a white circle around it and is labeled “GRB 230307A kilonova.”
This graphic presentation compares the spectral data of GRB 230307A’s kilonova as observed by NASA’s James Webb Space Telescope and a kilonova model. Both show a distinct peak in the region of the spectrum associated with tellurium, with the area shaded in red. The detection of tellurium, which is rarer than platinum on Earth, marks Webb’s first direct look at an individual heavy element from a kilonova.

At later times it would have been impossible to study this kilonova from the ground, but these were the perfect conditions for Webb’s NIRCam (Near-Infrared Camera) and NIRSpec (Near-Infrared Spectrograph) instruments to observe this tumultuous environment. The spectrum has broad lines that show the material is ejected at high speeds, but one feature is clear: light emitted by tellurium, an element rarer than platinum on Earth.

The highly sensitive infrared capabilities of Webb helped scientists identify the home address of the two neutron stars that created the kilonova: a spiral galaxy about 120,000 light-years away from the site of the merger.

Prior to their venture, they were once two normal massive stars that formed a binary system in their home spiral galaxy. Since the duo was gravitationally bound, both stars were launched together on two separate occasions: when one among the pair exploded as a supernova and became a neutron star, and when the other star followed suit.

In this case, the neutron stars remained as a binary system despite two explosive jolts and were kicked out of their home galaxy. The pair traveled approximately the equivalent of the Milky Way galaxy’s diameter before merging several hundred million years later.

Scientists expect to find even more kilonovae in the future due to the increasing opportunities to have space and ground-based telescopes work in complementary ways to study changes in the universe. For example, while Webb can peer deeper into space than ever before, the remarkable field of view of NASA’s upcoming Nancy Grace Roman Space Telescope will enable astronomers to scout where and how frequently these explosions occur.

“Webb provides a phenomenal boost and may find even heavier elements,” said Ben Gompertz, a co-author of the study at the University of Birmingham in the UK. “As we get more frequent observations, the models will improve and the spectrum may evolve more in time. Webb has certainly opened the door to do a lot more, and its abilities will be completely transformative for our understanding of the universe.”

These findings have been published in the journal Nature.

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.

      On Nov. 28, 1983, space shuttle Columbia took to the skies for its sixth trip into space on the first dedicated science mission using the Spacelab module provided by the European Space Agency (ESA). The longest shuttle mission at the time also included many other firsts. Aboard Columbia to conduct dozens of science experiments, the first six-person crew of Commander John W. Young, making his record-breaking sixth spaceflight, Pilot Brewster H. Shaw, Mission Specialists Owen K. Garriott and Robert A.R. Parker, and the first two payload specialists, American Byron K. Lichtenberg and German Ulf Merbold representing ESA, the first non-American to fly on a U.S. space mission. During the 10-day Spacelab 1 flight, the international team of astronauts conducted 72 experiments in a wide variety of science disciplines.

Lichtenberg, standing left, and Ulf Merbold of West Germany representing the European Space Agency. Right: The payload patch for Spacelab 1.
      In August 1973, NASA and the European Space Research Organization, the forerunner of today’s ESA, agreed on a cooperative plan to build a reusable laboratory called Spacelab to fly in the space shuttle’s cargo bay. In exchange for ESA building the pressurized modules and unpressurized pallets, NASA provided flight opportunities for European astronauts. In December 1977, ESA named physicist Merbold of the Max Planck Institute in West Germany, physicist Wubbo Ockels of The Netherlands, and astrophysicist Claude Nicollier of Switzerland as payload specialist candidates for the first Spacelab mission. In September 1982, ESA selected Merbold as the prime crew member to fly the mission and Ockels as his backup. Nicollier had in the meantime joined NASA’s astronaut class of 1980 as a mission specialist candidate. In 1978, NASA selected biomedical engineer Lichtenberg of the Massachusetts Institute of Technology as its payload specialist with physicist Michael L. Lampton of CalTech as his backup. In April 1982, NASA assigned the orbiter crew of Young, Shaw, Garriott, and Parker. As commander of STS-9, Young made a record-breaking sixth flight into space. The mission’s pilot Shaw, an astronaut from the 1978 class, made his first trip into space. The two mission specialists had a long history with NASA – Garriott, selected as an astronaut in 1965, completed a 59-day stay aboard the Skylab space station in 1973, and Parker, selected in 1967, made his first spaceflight after a 16-year wait. Although the crew included only two veterans, it had the most previous spaceflight experience of any crew up to that time – 84 days between Young’s and Garriott’s earlier missions.

Middle: Workers place the Spacelab module and pallet into Columbia’s payload bay in KSC’s Orbiter Processing Facility. Right: The Spacelab pallet, top, pressurized long module, and tunnel in Columbia’s payload bay.
      The pressurized module for the first Spacelab mission arrived at KSC on Dec. 11, 1981, from its manufacturing facility in Bremen, West Germany. Additional components arrived throughout 1982 as workers in KSC’s Operations and Checkout Building integrated the payload racks into the module. The ninth space shuttle mission saw the return of the orbiter Columbia to space, having flown the first five flights of the program. Since it arrived back at KSC after STS-5 on Nov. 22, 1982, engineers in the Orbiter Processing Facility (OPF) modified Columbia to prepare it for the first Spacelab mission. The completed payload, including the pressurized module, the external pallet, and the transfer tunnel, rolled over to the OPF, where workers installed it into Columbia’s payload bay on Aug. 16, 1983.

      Rollover of Columbia to the Vehicle Assembly Building (VAB) took place on Sept. 24, where workers mated it with an external tank (ET) and two solid rocket boosters (SRBs). Following integrated testing, the stack rolled out to Launch Pad 39A four days later for a planned Oct. 29 liftoff. However, on Oct. 14, managers called off that initial launch attempt after discovering that the engine nozzle of the left hand SRB contained the same material that nearly caused a burn through during STS-8. The replacement of the nozzle required a rollback to the VAB. Taking place on Oct. 17, it marked the first rollback of a flight vehicle in the shuttle’s history. Workers in the VAB demated the vehicle and destacked the left hand SRB to replace its nozzle. Columbia temporarily returned to the OPF on Oct. 19, where workers replaced its fuel cells using three borrowed from space shuttle Discovery and also replaced its waste collection system. Columbia returned to the VAB on Nov. 3 for remating with its ET and SRBs and rolled back out to the launch pad on Nov. 8.

      On Nov. 28, 1983, Columbia thundered off KSC’s Launch Pad 39A to begin the STS-9 mission. The shuttle entered an orbit inclined 57 degrees to the equator, the highest inclination U.S. spaceflight at the time, allowing the astronauts to observe about 80 percent of the Earth’s landmasses. Mounted inside Columbia’s payload bay, the first Spacelab 18-foot long module provided a shirt-sleeve environment for the astronauts to conduct scientific experiments in a variety of disciplines. During the Spacelab 1 mission, the STS-9 crew carried out 72 experiments in atmospheric and plasma physics, astronomy, solar physics, materials sciences, technology, astrobiology, and Earth observations. For the first time in spaceflight history, the crew divided into two teams working opposite 12-hour shifts, allowing science to be conducted 24 hours a day. The Tracking and Data Relay Satellite, launched the previous April during the STS-6 mission, and now fully operational, enabled transmission of television and significant amounts of science data to the Payload Operations Control Center, located in the Mission Control Center at NASA’s Johnson Space Center in Houston.

      Upon reaching orbit, the crew opened the payload bay doors and deployed the shuttle’s radiators. Shortly after, following a few tense minutes during which the astronauts struggled with a balky hatch, they opened it, translated down the transfer tunnel, and entered Spacelab for the first time. Garriott, Lichtenberg, and Merbold activated the module and turned on the first experiments. For the next nine days, the Red Team of Young, Parker, and Merbold, and the Blue Team of Shaw, Garriott, and Lichtenberg performed flawlessly to carry out the experiments. Young and Shaw managed the shuttle’s systems while the mission and payload specialists conducted the bulk of the research. With ample consumables available, Mission Control granted them an extra day in space to complete additional science. One afternoon, the astronauts chatted with U.S. President Ronald W. Reagan in the White House and German Chancellor Helmut Kohl, attending the European Community Summit in Athens, Greece. The two leaders praised the astronauts for their scientific work and the cooperation between the two countries that enabled the flight to take place.

      On Dec. 8, their last day in space, the crew finished the experiments, closed up the Spacelab module, and strapped themselves into their seats to prepare for their return to Earth. Five hours before the scheduled landing, during thruster firings one of Columbia’s five General Purpose Computers (GPC) failed, followed six minutes later by a second GPC. Mission Control decided to delay the landing until the crew could fix the problem. Young and Shaw  brought the second GPC back up but had no luck with the first. Meanwhile, one of Columbia’s Inertial Measurement Units, used for navigation, failed. Finally, after eight hours of troubleshooting, the astronauts fired the shuttle’s Orbital Maneuvering System engines to begin the descent from orbit. Young piloted Columbia to a smooth landing on a lakebed runway at Edwards Air Force Base in California’s Mojave Desert, completing 166 orbits around the Earth in 10 days, 6 hours, and 47 minutes, at the time the longest shuttle flight. Shortly before landing, a hydrazine leak caused two of the orbiter’s three Auxiliary Power Units (APU) to catch fire. The fire burned itself out, causing damage in the APU compartment but otherwise not affecting the landing. The astronauts safely exited the spacecraft without incident. On Dec. 14, NASA ferried Columbia back to KSC to remove the Spacelab module from the payload bay. In January 1984, Columbia returned to its manufacturer, Rockwell International in Palmdale, California, where workers spent the next two years refurbishing NASA’s first orbiter before its next mission, STS-61C, in January 1986.

      The journal Science published preliminary results from Spacelab 1 in their July 13, 1984, issue. The two Spacelab modules flew a total of 16 times, the last one during the STS-90 Neurolab mission in April 1998. The module that flew on STS-9 and eight other missions is displayed at the Stephen F. Udvar-Hazy Center of the Smithsonian Institution’s National Air and Space Museum in Chantilly, Virginia, while the other module resides at the Airbus Defence and Space plant in Bremen, Germany, not on public display.

      3 Min Read Webb Telescope: A prominent protostar in Perseus
      Webb Space Telescope reveals intricate details of the Herbig Haro object 797 (HH 797). This new Picture of the Month from the NASA/ESA/CSA James Webb Space Telescope reveals intricate details of the Herbig Haro object 797 (HH 797). Herbig-Haro objects are luminous regions surrounding newborn stars (known as protostars), and are formed when stellar winds or jets of gas spewing from these newborn stars form shockwaves colliding with nearby gas and dust at high speeds. HH 797, which dominates the lower half of this image, is located close to the young open star cluster IC 348, which is located near the eastern edge of the Perseus dark cloud complex. The bright infrared objects in the upper portion of the image are thought to host two further protostars.
      This image was captured with Webb’s Near-InfraRed Camera (NIRCam). Infrared imaging is powerful in studying newborn stars and their outflows, because the youngest stars are invariably still embedded within the gas and dust from which they are formed. The infrared emission of the star’s outflows penetrates the obscuring gas and dust, making Herbig-Haro objects ideal for observation with Webb’s sensitive infrared instruments. Molecules excited by the turbulent conditions, including molecular hydrogen and carbon monoxide, emit infrared light that Webb can collect to visualise the structure of the outflows. NIRCam is particularly good at observing the hot (thousands of degree Celsius) molecules that are excited as a result of shocks.

      The NASA/ESA/CSA James Webb Space Telescope reveals intricate details of the Herbig Haro object 797 (HH 797). Herbig-Haro objects are luminous regions surrounding newborn stars (known as protostars), and are formed when stellar winds or jets of gas spewing from these newborn stars form shockwaves colliding with nearby gas and dust at high speeds.

The bright infrared objects in the upper portion of the image are thought to host two further protostars. This image was captured with Webb’s Near-InfraRed Camera (NIRCam).ESA/Webb, NASA & CSA, T. Ray (Dublin Institute for Advanced Studies) Using ground-based observations, researchers have previously found that for cold molecular gas associated with HH 797, most of the red-shifted gas (moving away from us) is found to the south (bottom right), while the blue-shifted gas (moving towards us) is to the north (bottom left). A gradient was also found across the outflow, such that at a given distance from the young central star, the velocity of the gas near the eastern edge of the jet is more red-shifted than that of the gas on the western edge. Astronomers in the past thought this was due to the outflow’s rotation. In this higher resolution Webb image, however, we can see that what was thought to be one outflow is in fact made up of two almost parallel outflows with their own separate series of shocks (which explains the velocity asymmetries). The source, located in the small dark region (bottom right of center), and already known from previous observations, is therefore not a single but a double star. Each star is producing its own dramatic outflow. Other outflows are also seen in this image, including one from the protostar in the top right of center along with its illuminated cavity walls.
      HH 797 resides directly north of HH 211 (separated by approximately 30 arcseconds), which was the feature of a Webb image release in September 2023.

      Record-breaking NASA astronaut Frank Rubio provides the first Spanish-language video tour of humanity’s home in space – the International Space Station.
      Rubio welcomes the public aboard the microgravity science laboratory in a behind-the-scenes look at living and working in space recorded during his 371-day mission aboard the space station, the longest single spaceflight in history by an American.
      The station tour is available to watch on the agency’s NASA+ streaming platform, NASA app, NASA Television, YouTube, and the agency’s website.
      Continuously inhabited for more than 23 years, the space station is a scientific platform where crew members conduct experiments across multiple disciplines of research, including Earth and space science, biology, human physiology, physical sciences, and technology demonstrations that could not be performed on Earth.
      The crew living aboard the station are the hands of thousands of researchers on the ground conducting more than 3,300 experiments in microgravity. During his record-breaking mission, Rubio spent many hours contributing to scientific activities aboard the orbiting laboratory, conducting everything from human health studies to plant research.
      Rubio returned to Earth in September, having completed approximately 5,936 orbits of the Earth and a journey of more than 157 million miles during his first spaceflight, roughly the equivalent of 328 trips to the Moon and back.

      Artemis II Astronauts View SLS Core Stage at Michoud
      Artemis II NASA astronauts Reid Wiseman and Christina Koch of NASA, and CSA (Canadian Space Agency) astronaut Jeremy Hansen viewed the core stage for the SLS (Space Launch System) rocket at the agency’s Michoud Assembly Facility on Nov. 16. The three astronauts, along with NASA’s Victor Glover, will launch atop the rocket stage to venture around the Moon on Artemis II, the first crewed flight for Artemis.
      From left, Artemis II NASA astronaut Reid Wiseman, CSA (Canadian Space Agency) astronaut Jeremy Hansen, NASA astronaut Christina Koch, and Boeing’s Amanda Gertjejansen view the core stage for the SLS (Space Launch System) rocket at the agency’s Michoud Assembly Facility on Nov. 16.NASA / Michael DeMocker The SLS core stage, towering at 212 feet, is the backbone of the Moon rocket and includes two massive propellant tanks that collectively hold 733,000 gallons of propellant to help power the stage’s four RS-25 engines. NASA, Boeing, the core stage lead contractor, along with Aerojet Rocketdyne, an L3Harris Technologies company and the RS-25 engines lead contractor, are in the midst of conducting final integrated testing on the fully assembled rocket stage. At launch and during ascent to space, the Artemis astronauts inside NASA’s Orion spacecraft will feel the power of the rocket’s four RS-25 engines producing more than 2 million pounds of thrust for a full eight minutes. The mega rocket’s twin solid rocket boosters, which flank either side of the core stage, will each add an additional 3.6 million pounds of thrust for two minutes.

NASA / Michael DeMocker The astronauts’ visit to Michoud coincided with the first anniversary of the launch of Artemis I. The uncrewed flight test of SLS and Orion was the first in a series of increasingly complex missions for Artemis as the agency works to return humans to the lunar surface and develop a long-term presence there for discovery and exploration.
      NASA is working to land the first woman and first person of color on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, advanced spacesuits and rovers, the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single mission.

      Marshall Makes Impact at University of Alabama’s 8th Annual Space Days
      By Celine Smith
      Team members from NASA’s Marshall Space Flight Center participated in the 8th annual Space Days at UA (University of Alabama) on Nov 14-16, where more than 500 students met with experts from NASA and aerospace companies to learn more about the space industry.
      During the three-day program, Marshall team members conducted outreach presentations and updates about the Artemis missions, HLS (Human Landing System), and other NASA programs, as well as how students can get involved in NASA’s internship program.
      NASA astronaut Bob Hines delivers a presentation entitled, “An Astronaut’s Journey,” during the 8th annual Space Days at the UA on Nov. 16.Matthew Wood Kicking off the event was Aaron Houin, an engineer on the aerospace vehicle design and mission analysis team at Marshall. Houin delivered a detailed presentation on orbital mechanics and vehicle properties. Houin is no stranger to the classroom, as he is currently earning his doctorate at UA’s Astrodynamics and Space Research Laboratory and was eager to give back to his alma mater.
      “Having been in their position studying the same theories, I emphasized how their coursework directly applies to physics-based modeling and trajectory design,” Houin said. “I’m hopeful sharing my experiences of transitioning from the classroom to the workplace will help others find similar success.”
      The Marshall team also conducted an hour-long panel discussion and Q&A segment allowing students to learn more about the fields of aerospace and aeronautic research. Panelists included Christy Gattis, cross-program integration lead, and Kent Criswell, lead systems engineer, both representing the HLS team, as well as Tim Smith, senior mission manager of the TDM (Technology Demonstration Missions) program.

Vanderslice shared insight about “America’s Rocket Factory” and progress for the agency’s Artemis II missions, including the recent installation of all four RS-25 engines onto the 212-ft-tall SLS core stage.
      UA students also received a Tech Talk presentation focused on the SCaN (Space Communications and Navigation) program and related internship opportunities from team members from NASA’s Glenn Research Center and NASA Headquarters. Panelists included Dawn Brooks, program specialist at NASA Headquarters; Timothy Gallagher, senior project lead, and Molly Kearns, digital media specialist, all three representing SCaN’s Policy and Strategic Communications office.
      And in true “One NASA” collaboration, joining the Glenn contingency for this Tech Talk was once again, Tim Smith, providing related updates on the Deep Space Optical Communications and the Laser Communications Relay Demonstration experiments.
      Holly Ellis, communication specialist, and Tim Smith, senior mission manager, both of the Technology Demonstration Missions Program, speak with students during Space Days at the University of Alabama on Nov. 15. NASA/Christopher Blair The annual Space Days event concluded with NASA astronaut Bob Hines delivering a special presentation entitled, “An Astronaut’s Journey” to nearly 100 students, staff and industry partners. Hines completed his first spaceflight as a mission specialist for NASA’s SpaceX Crew-4 mission, serving as flight engineer of Expedition 67/68 aboard the International Space Station. 
      Space Days is hosted by the UA College of Engineering and their staff shared how crucial it is to have support from aerospace industry partners willing to visit campus and meet students. Key partners exhibiting and presenting included Lockheed Martin, United Launch Alliance, Alabama Space Grant Consortium, and others.
      “By the time our students attend a career fair, apply for an internship, or pursue cooperative education, they will have learned about these companies in a smaller setting and begin to consider the many pathways to success,” said Tru Livaudais, director of external affairs for UA College of Engineering. “This event offers all UA students – regardless of majors and specialties – a chance to explore future career possibilities and how to be a part of the cutting-edge research and opportunities in the space industry.”

      NASA Telescope Data Becomes Music You Can Play
      For millennia, musicians have looked to the heavens for inspiration. Now a new collaboration is enabling actual data from NASA telescopes to be used as the basis for original music that can be played by humans.
      Since 2020, the “sonification” project at NASA’s Chandra X-ray Center has translated the digital data taken by telescopes into notes and sounds. This process allows the listener to experience the data through the sense of hearing instead of seeing it as images, a more common way to present astronomical data.
      The Galactic Center sonification, using data from NASA’s Chandra, Hubble, and Spitzer space telescopes, has been translated into a new composition with sheet music and score. Working with a composer, this soundscape can be played by musicians. The full score and sheet music for individual instruments is available at: https://chandra.si.edu/sound/symphony.htmlComposition: NASA/CXC/SAO/Sophie Kastner A new phase of the sonification project takes the data into different territory. Working with composer Sophie Kastner, the team has developed versions of the data that can be played by musicians.
      “It’s like a writing a fictional story that is largely based on real facts,” said Kastner. “We are taking the data from space that has been translated into sound and putting a new and human twist on it.”
      This pilot program focuses on data from a small region at the center of our Milky Way galaxy where a supermassive black hole resides. NASA’s Chandra X-ray Observatory, Hubble Space Telescope, and retired Spitzer Space Telescope have all studied this area, which spans about 400 light-years across.
      “We’ve been working with these data, taken in X-ray, visible, and infrared light, for years,” said Kimberly Arcand, Chandra visualization and emerging technology scientist. “Translating these data into sound was a big step, and now with Sophie we are again trying something completely new for us.”
      In the data sonification process, computers use algorithms to mathematically map the digital data from these telescopes to sounds that humans can perceive. Human musicians, however, have different capabilities than computers.
      Kastner chose to focus on small sections of the image in order to make the data more playable for people. This also allowed her to create spotlights on certain parts of the image that are easily overlooked when the full sonification is played.
      “I like to think of it as creating short vignettes of the data, and approaching it almost as if I was writing a film score for the image,” said Kastner. “I wanted to draw listener’s attention to smaller events in the greater data set.”
      A musical ensemble performs soundscape that composer Sophie Katsner created using data sonifications from NASA’s Chandra, Hubble and Spitzer space telescopes. Based in Montreal, Ensemble Éclat is dedicated to the performance of contemporary classical music and promoting the works of emerging composers. (NASA/CXC/A. Jubett & Priam David) The result of this trial project is a new composition based upon and influenced by real data from NASA telescopes, but with a human take.
      “In some ways, this is just another way for humans to interact with the night sky just as they have throughout recorded history,” says Arcand. “We are using different tools but the concept of being inspired by the heavens to make art remains the same.”
      Kastner hopes to expand this pilot composition project to other objects in Chandra’s data sonification collection. She is also looking to bring in other musical collaborators who are interested in using the data in their pieces.
      Sophie Kastner’s Galactic Center piece is entitled “Where Parallel Lines Converge.” If you are a musician who wants to try playing this sonification at home, check out the sheet music at: https://chandra.si.edu/sound/symphony.html.
      The piece was recorded by Montreal based Ensemble Éclat conducted by Charles-Eric LaFontaine on July 19, 2023, at McGill University.
      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.

      Cube Quest Concludes: Wins, Lessons Learned from Centennial Challenge
      By Savannah Bullard
      Artemis I launched from NASA’s Kennedy Space Center on Nov. 16, 2022, penning a new era of space exploration and inching the agency closer to sending the first woman and first person of color to the lunar surface.
      Aboard the Space Launch System (SLS) rocket were 10 small satellites, no bigger than shoeboxes, whose goal was to detach and capably perform operations near and beyond the Moon. One of those satellites was a product of the Cube Quest Challenge, a NASA-led prize competition that asked citizen innovators to design, build, and deliver flight-qualified satellites called CubeSats that could perform its mission independently of the Artemis I mission.
      Small satellites, called CubeSats, are shown secured inside NASA’s Orion stage adapter at NASA’s Kennedy Space Center on Aug. 5, 2021. One of these CubeSats belonged to Team Miles, one of the three finalists in the Cube Quest Centennial Challenge. The ring-shaped stage adapter was connected to the Space Launch System’s Interim Cryogenic Propulsion Stage, with the Orion spacecraft secured on top. The CubeSats’ mission was to detach from the stage adapter, then fly near and beyond the Moon to conduct a variety of science experiments and technology demonstrations to expand our knowledge of the lunar surface during the Artemis I mission.NASA/Cory Huston Cube Quest is the agency’s first in-space public prize competition. Opened in 2015, the challenge began with four ground-based tournaments, which awarded almost $500,000 in prizes. Three finalists emerged from the ground competition with a ticket to hitch a ride aboard the SLS as a secondary payload – and win the rest of the competition’s $5 million prize purse, NASA’s largest-ever prize offering to date – in 2022.
      Of the three finalists, Team Miles was the sole team to make the trip on Artemis I successfully. Shortly after a successful deployment in space, controllers detected downlink signals and processed them to confirm whether the CubeSat was operational. This remains the latest update for the Team Miles CubeSat.
      “We’re still celebrating the many wins that were borne out of Cube Quest,” said Centennial Challenges Program Manager Denise Morris. “The intent of the challenge was to reward citizen inventors who successfully advance the CubeSat technologies needed for operations on the Moon and beyond, and I believe we accomplished this.”
      Innovation rarely comes without error, but according to Challenge Manager Naveen Vetcha, who supports Centennial Challenges through Jacobs Space Exploration Group, even after everything goes as expected, there is no guarantee that scientists will reach their desired outcomes.
      “Given the magnitude of what we can and do accomplish every day at NASA, it comes with the territory that not every test, proposal, or idea will come out with 100 percent success,” Vetcha said. “We have set ambitious goals, and challenging ourselves to change what’s possible will inevitably end with examples of not meeting our stretch goals. But, with each failure comes more opportunities and lessons to carry forward. In the end, our competitors created technologies that will enable affordable deep space CubeSats, which, to me, is a big win.”
      Although Team Miles may have made it furthest in the Cube Quest Challenge, having launched its CubeSat as a secondary payload aboard Artemis I, the team continues to participate in the challenge long after launch.
      “From Team Miles, Miles Space LLC was created and is still in business,” said Jan McKenna, Team Miles’ project manager and safety lead. “Miles Space is developing and selling the propulsion system designed for our craft to commercial aerospace companies, and we’ve expanded to be able to create hardware for communications along with our CubeSat developments.”
      The next steps for Miles Space LLC include seeing through their active patent applications, establishing relationships with potential clients, and continuing to hunt for a connection with their flying CubeSat. Another finalist team, Cislunar Explorers, is currently focused on using their lessons learned to benefit the global small satellite community.
      “I utilized the contacts I made through Cube Quest and the other Artemis Secondary Payloads for my thesis research,” said Aaron Zucherman, Cislunar Explorers’ project manager. “This has enabled me to find partnerships and consulting work with other universities and companies where I have shared my experiences learning the best ways to build interplanetary CubeSats.”
      This challenge featured teams from diverse educational and commercial backgrounds. Several team members credited the challenge as a catalyst in their graduate thesis or Ph.D. research, but one young innovator says Cube Quest completely redirected his entire career trajectory.
      Project Selene team lead, Braden Oh, competed with his peers at La Cañada High School in La Cañada, California. Oh’s team eventually caught the attention of Kerri Cahoy at the Massachusetts Institute of Technology, and the designs were similar enough that Cahoy invited the two teams to merge. The exposure gained through this partnership was a powerful inspiration for Oh and his peers.
      “I originally intended to apply to college as a computer science major, but my experiences in Cube Quest inspired me to study engineering instead,” Oh said. “I saw similar stories unfold for a number of my teammates; one eventually graduated from MIT and another now works for NASA.”
      Cube Quest is managed out of NASA’s Ames Research Center. The competition is a part of NASA’s Centennial Challenges, which is housed at the agency’s Marshall Space Flight Center. Centennial Challenges is a part of NASA’s Prizes, Challenges, and Crowdsourcing program in the Space Technology Mission Directorate.

      The Heat is On! NASA’s ‘Flawless’ Heat Shield Demo Passes the Test
      A little more than a year ago, a NASA flight test article came screaming back from space at more than 18,000 mph, reaching temperatures of nearly 2,700 degrees Fahrenheit before gently splashing down in the Pacific Ocean. At that moment, it became the largest blunt body – a type of reentry vehicle that creates a heat-deflecting shockwave – ever to reenter Earth’s atmosphere.
      The Low-Earth Orbit Flight Test of an Inflatable Decelerator, or LOFTID, launched Nov. 10, 2022, aboard a ULA (United Launch Alliance) Atlas V rocket and successfully demonstrated an inflatable heat shield. Also known as a Hypersonic Inflatable Aerodynamic Decelerator, or HIAD, aeroshell, this technology could allow larger spacecraft to safely descend through the atmospheres of celestial bodies like Mars, Venus, and even Saturn’s moon, Titan.
      The Low-Earth Orbit Flight Test of an Inflatable Decelerator, or LOFTID, spacecraft is pictured after its atmospheric re-entry test in November 2022.NASA/Greg Swanson “Large-diameter aeroshells allow us to deliver critical support hardware, and potentially even crew, to the surface of planets with atmospheres,” said Trudy Kortes, director of Technology Demonstrations at NASA Headquarters. “This capability is crucial for the nation’s ambition of expanding human and robotic exploration across our solar system.”
      NASA has been developing HIAD technologies for over a decade, including two smaller scale suborbital flight tests before LOFTID. In addition to this successful tech demo, NASA is investigating future applications, including partnering with commercial companies to develop technologies for small satellite reentry, aerocapture, and cislunar payloads.
      “This was a keystone event for us, and the short answer is: It was highly successful,” said LOFTID Project Manager Joe Del Corso. “Our assessment of LOFTID concluded with the promise of what this technology may do to empower the exploration of deep space.”
      Due to the success of the LOFTID tech demo, NASA announced under its Tipping Point program that it would partner with ULA to develop and deliver the “next size up,” a larger 12-meter HIAD aeroshell for recovering the company’s Vulcan engines from low Earth orbit for reuse.
      The LOFTID team recently held a post-flight analysis assessment of the flight test at NASA’s Langley Research Center. Their verdict?
      Upon recovery, the team discovered LOFTID appeared pristine, with minimal damage, meaning its performance was, as Del Corso puts it, “Just flawless.”
      View some interesting visual highlights from LOFTID’s flight test.
      LOFTID splashed down in the Pacific Ocean several hundred miles off the east coast of Hawaii and only about eight miles from the recovery ship’s bow – almost exactly as modeled. A crew got on a small boat and retrieved and hoisted LOFTID onto the recovery ship.
      “The LOFTID mission was important because it proved the cutting-edge HIAD design functioned successfully at an appropriate scale and in a relevant environment,” said Tawnya Laughinghouse, manager of the TDM (Technology Demonstrations Missions) program office at NASA’s Marshall Space Flight Center.
      Marshall supported the Langley-led LOFTID project, providing avionics flight hardware, including the data acquisition system, the inertial measurement unit, and six camera pods. Marshall engineers also performed thermal and fluids analyses and modeling in support of the LOFTID re-entry vehicle inflation system and aeroshell designs.
      The LOFTID demonstration was a public private-partnership with ULA funded by STMD and managed by the Technology Demonstration Mission Program, executed by NASA Langley with contributions from across NASA centers. Multiple U.S. small businesses contributed to the hardware. NASA’s Launch Services Program was responsible for NASA’s oversight of launch operations.

      4 Min Read NASA’s Webb Reveals New Features in Heart of Milky Way
      Sagitarius C (NIRCam) Credits: NASA, ESA, CSA, STScI, and S. Crowe (University of Virginia). The latest image from NASA’s James Webb Space Telescope shows a portion of the dense center of our galaxy in unprecedented detail, including never-before-seen features astronomers have yet to explain. The star-forming region, named Sagittarius C (Sgr C), is about 300 light-years from the Milky Way’s central supermassive black hole, Sagittarius A*.
      Image: Sagitarius C (NIRCam)
      The NIRCam (Near-Infrared Camera) instrument on NASA’s James Webb Space Telescope’s reveals a portion of the Milky Way’s dense core in a new light. An estimated 500,000 stars shine in this image of the Sagittarius C (Sgr C) region, along with some as-yet unidentified features. A large region of ionized hydrogen, shown in cyan, contains intriguing needle-like structures that lack any uniform orientation.NASA, ESA, CSA, STScI, and S. Crowe (University of Virginia). “There’s never been any infrared data on this region with the level of resolution and sensitivity we get with Webb, so we are seeing lots of features here for the first time,” said the observation team’s principal investigator Samuel Crowe, an undergraduate student at the University of Virginia in Charlottesville. “Webb reveals an incredible amount of detail, allowing us to study star formation in this sort of environment in a way that wasn’t possible previously.”
      “The galactic center is the most extreme environment in our Milky Way galaxy, where current theories of star formation can be put to their most rigorous test,” added professor Jonathan Tan, one of Crowe’s advisors at the University of Virginia.
      Protostars
      Amid the estimated 500,000 stars in the image is a cluster of protostars – stars that are still forming and gaining mass – producing outflows that glow like a bonfire in the midst of an infrared-dark cloud. At the heart of this young cluster is a previously known, massive protostar over 30 times the mass of our Sun. The cloud the protostars are emerging from is so dense that the light from stars behind it cannot reach Webb, making it appear less crowded when in fact it is one of the most densely packed areas of the image. Smaller infrared-dark clouds dot the image, looking like holes in the starfield. That’s where future stars are forming.
      Webb’s NIRCam (Near-Infrared Camera) instrument also captured large-scale emission from ionized hydrogen surrounding the lower side of the dark cloud, shown cyan-colored in the image. Typically, Crowe says, this is the result of energetic photons being emitted by young massive stars, but the vast extent of the region shown by Webb is something of a surprise that bears further investigation. Another feature of the region that Crowe plans to examine further is the needle-like structures in the ionized hydrogen, which appear oriented chaotically in many directions.
      “The galactic center is a crowded, tumultuous place. There are turbulent, magnetized gas clouds that are forming stars, which then impact the surrounding gas with their outflowing winds, jets, and radiation,” said Rubén Fedriani, a co-investigator of the project at the Instituto Astrofísica de Andalucía in Spain. “Webb has provided us with a ton of data on this extreme environment, and we are just starting to dig into it.”
      Image: Sagitarius C Features
      Approximate outlines help to define the features in the Sagittarius C (Sgr C) region. Astronomers are studying data from NASA’s James Webb Space Telescope to understand the relationship between these features, as well as other influences in the chaotic galaxy center.NASA, ESA, CSA, STScI, Samuel Crowe (UVA) Around 25,000 light-years from Earth, the galactic center is close enough to study individual stars with the Webb telescope, allowing astronomers to gather unprecedented information on how stars form, and how this process may depend on the cosmic environment, especially compared to other regions of the galaxy. For example, are more massive stars formed in the center of the Milky Way, as opposed to the edges of its spiral arms?
      “The image from Webb is stunning, and the science we will get from it is even better,” Crowe said. “Massive stars are factories that produce heavy elements in their nuclear cores, so understanding them better is like learning the origin story of much of the universe.”
      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.
