NASA’s SLS (Situation Commence Intention) rocket core stage for the Artemis II mission is contained within the Automobile Assembly Constructing at the company’s Kennedy Situation Heart.
Tugboats and towing vessels moved the barge and core stage 900-miles to the Florida spaceport from NASA’s Michoud Assembly Facility, where it became as soon as manufactured and assembled.
Crew contributors with NASA’s Exploration Ground Programs Program safely transferred the 212-foot-huge core stage from the company’s Pegasus barge, which arrived at NASA Kennedy’s Complex 39 flip basin wharf on July 23, onto the self-propelled module transporter, which is used to pass gargantuan substances of hardware. It became as soon as then rolled to the Automobile Assembly Constructing switch aisle where groups will course of it except it’s ready for rocket stacking operations.
Within the upcoming months, groups will mix the rocket core stage atop the mobile launcher with the extra Artemis II flight hardware, in conjunction with the twin proper rocket boosters, open car stage adapter, and the Orion spacecraft.
The Artemis II test flight will doubtless be NASA’s first mission with crew under the Artemis campaign, sending NASA astronauts Victor Glover, Christina Koch, and Reid Wiseman, as successfully as CSA (Canadian Situation Company) astronaut Jeremy Hansen, on a 10-day mosey spherical the Moon and lend a hand.

Quiz Chris Calfee about his well-liked memory from his 38-twelve months profession at NASA’s Marshall Situation Flight Heart and likewise you’ll stumble on it’s a tricky quiz to answer to.
That’s because there hold been many memories.
Calfee became as soon as the integrator for the upper stage spacecraft for the Marshall-led Chandra X-Ray Observatory, which marked its Twenty fifth open anniversary July 23. He’s worked with Demonstration of Independent Rendezvous Know-how (DART), a technology mission aimed at demonstrating that a spacecraft may per chance well presumably independently rendezvous with an orbiting satellite tv for computer with out human intervention. Calfee became as soon as the booster manager for the Ares I-X test flight, which he points to as one other profession highlight.
And then there’s his well-liked memory – working with NASA’s SLS (Situation Commence Intention) rocket and gazing the 2022 Artemis I open from NASA’s Kennedy Situation Heart.
“I’ve been fortunate in my profession to hold the alternatives I’ve had with NASA,” stated Calfee, the SLS Spacecraft Payload Integration and Evolution (SPIE) direct manager. “Seeing the Chandra mission cruise and the success it has had is superior. Being able to work DART from cradle to grave, in conjunction with its flight, became as soon as unforgettable. Nevertheless I’d wish to squawk having the flexibility to characterize the SLS SPIE Element Position of enterprise at Kennedy’s Commence Retain watch over Heart and seeing Artemis I take away darkness from the evening sky is the proudest second.”
Because the SLS Spacecraft/Payload Integration and Evolution direct manager, Calfee’s obligations consist of overseeing the plan and handing over key adapter hardware for SLS rockets that will energy the principle crewed Artemis missions and first flight of SLS in its evolved Block 1B configuration. The hardware comprises the open car stage adapter, meantime cryogenic propulsion stage, and the Orion stage adapter – and the present stage adapter for SLS Block 1B. The SPIE Element Position of enterprise serves a key role within the a success execution of the SLS mission, every for the preliminary open skill as successfully because the evolution of subsequent rocket configurations.
NASA moved a step nearer to the Artemis II open with the July shipment of the SLS core stage to Kennedy from the company’s Michoud Assembly Facility. Calfee and his group hold the adapters total for Artemis II and may per chance well presumably rapidly ship them to Kennedy for open preparations. As work advances toward Artemis II, Calfee looks lend a hand on the Artemis I open as a “surreal skills.” Nevertheless he assign his party on shield as he watched the preliminary moments of the flight.
“The force became as soon as on the SPIE hardware to enact the job for SLS as we tracked the a success booster burn and separation, and then the core stage’s unparalleled efficiency,” stated Calfee, who is from Newport, Tennessee, and a graduate of the College of Tennessee. “The meantime cryogenic propulsion (ICPS) stage 20-minute burn became as soon as roughly one and a half hours after open, followed by Orion spacecraft separation from the ICPS and Orion stage adapter, doubtlessly the most serious tournament of the mission from my standpoint. It became as soon as one other unprecedented support to peek the ICPS burn and the Orion separation tournament lag flawlessly.”
Memorable certainly.
Quiz of: Having a salvage out about forward to Artemis II and the Artemis campaign, what excites you most about the future of human living exploration and your group’s role it?
Calfee: For me personally, it’s moving correct to be a half of the future of human living flight and having the bogus to persuade that future. With admire to the SPIE group, it’s a identical feeling. Having the bogus to e-book a gaggle that has this kind of fundamental role and responsibility in our future is an huge skills.
Quiz of: Who or what drives/motivates you?
Calfee: The bogus to catch a difference, be a half of historical previous, and lead and mentor our future leaders.
Quiz of: Who or what inspired you to pursue an training/profession that led you to NASA and Marshall?
Calfee: My fogeys were my inspiration and provided me the bogus to pursue my training. Even supposing I followed the living program as a child, particularly the Apollo program and Moon landings, I never dreamed that I may per chance well presumably even hold the bogus to work for NASA. I found my ability to NASA by activity of an on-campus interview job unprejudiced, became as soon as invited to Marshall for a notice-up interview, and it grew to become a easy decision when an supply became as soon as made.
Quiz of: What advice enact that it’s doubtless you’ll presumably hold for workers early of their NASA profession or those in original leadership roles?
Calfee: For those early of their profession, maintain an originate thoughts and be intelligent to take on original challenges. Diversify the resume. For those in original leadership roles, never catch complacent. The second you assume that it’s doubtless you’ll presumably hold all of it found out, one thing will surprise and humble you. I adore the quote, “Fetch ecstatic being unhappy,” because I notify as a frontrunner, you are going to skills many unhappy moments.
Quiz of: What enact you skills doing along with your time while away from work?
Calfee: Spending time with my grandkids. I also skills homebrewing and wine making, and I doubtlessly exhaust too a lot time following and gazing school sports.

Crew contributors at NASA’s Marshall Situation Flight Heart no longer too prolonged within the past sat down with reigning Miss The US, Madison Marsh. To boot to her crown, Marsh is a second lieutenant within the United States Air Power and a broken-down intern who contributed to astrophysics analysis at Marshall. Witness to be taught more about her skills discovering out gamma-ray bursts and hear what advice she has for somebody attracted to a STEM profession. (NASA)
Thomas Brown has been named heart chief engineer and manager of the Chief Engineering Position of enterprise contained within the Engineering Directorate at NASA’s Marshall Situation Flight Heart, effective July 28.
In his role, Brown will doubtless be accountable for assuring the technical excellence and success of all Marshall-assigned spacecraft, propulsion, science payload, lifestyles enhance, and mission systems. He’ll provide educated technical leadership in planning, directing, and executing analysis, technology, ground and flight systems have and pattern, manufacturing, integration, and sustaining engineering for the Situation Commence Intention Program, Human Touchdown Intention Program, the Human Exploration Construction and Operations Position of enterprise, and the Science and Know-how Position of enterprise.
Brown beforehand served as director of the Propulsion Programs Division of the Engineering Directorate, since 2020. On this role, he managed a $68 million annual price range and oversaw a gaggle accountable for original and ongoing have and pattern activities for the propulsion substances and systems at Marshall and various NASA centers.
Because the aptitude lead for In-Situation Transportation Programs from 2018-2020, Brown led the Programs Functionality Leadership Crew of machine-dispute discipline matter consultants from across the company for the in-living transportation machine’s disciplines, which counterpoint NASA’s robotic and human exploration missions. From 2014 to 2018, he became as soon as the NASA Technical Fellow for Propulsion and the NASA Propulsion Functionality Lead, the company’s most senior propulsion discipline matter educated.
Between 2005 and 2014, Brown served as chief of two divisions contained within the Propulsion Programs Division, as successfully as technical advisor to the director of the Propulsion Programs Division at Marshall, where he assisted in interior technology investment planning and served in company and immoral-authorities stage assignments. In 2007, he done a one-twelve months developmental project at Glenn Research Heart as performing deputy manager of the Superior Capabilities Venture Position of enterprise.
Brown started his NASA profession at Marshall in 1999 as an aerospace engineer within the Situation Transportation Directorate, performing propulsion systems prognosis and integration. Before every thing working have, prognosis, and integration of the X-34 Basic Propulsion Intention and the Fastrac/MC-1 rocket engine, Brown’s activities hasty expanded into a astronomical fluctuate of propulsion technology pattern efforts. He served as chief engineer for quite a bit of of those efforts during every the 2nd Period Reusable Commence Automobile Program and the Next Period Commence Know-how Program. Explicit initiatives incorporated the Basic Propulsion and Auxiliary Propulsion Programs Know-how Venture and the ISTAR, Rocket Basically based Mixed Cycle technology mission.
Brown bought a bachelor’s stage in physics from Allegheny College in Meadville, Pennsylvania, sooner than earning his master’s and doctoral degrees in mechanical engineering from Vanderbilt College. He holds a U.S. patent and has published higher than 30 refereed journal publications, book sections, and convention complaints linked to classic combustion, evolved size tactics, propulsion technology, and propulsion systems prognosis and integration.

Part of a NASA-funded industrial living residence, Orbital Reef, under pattern by Blue Origin and Sierra Situation, no longer too prolonged within the past done a beefy-scale final burst force test as half of the company’s efforts for original destinations in low Earth orbit.
This milestone is half of a NASA Situation Act Agreement awarded to Blue Origin in 2021. Orbital Reef comprises substances provided by Sierra Situation, in conjunction with the LIFE (Spacious Built-in Flexible Environment) habitat structure.
Groups conducted the burst test on Sierra Situation’s LIFE habitat structure the utilization of sorting out capabilities at NASA’s Marshall Situation Flight Heart. The inflatable habitat is fabricated from high-power webbings and cloth that kind a proper structure as soon as pressurized. The multiple layers of soppy goods materials that catch up the shell are compactly stowed in a payload fairing and inflated when ready for utilize, enabling the habitat to open on a single rocket.
“Right here’s an exhilarating test by Sierra Situation for Orbital Reef, exhibiting industry’s dedication and skill to have revolutionary technologies and choices for future industrial destinations,” stated Angela Hart, manager of NASA’s Commercial Low Earth Orbit Construction Program at the company’s Johnson Situation Heart. “Each a success pattern milestone by our companions is every other step to achieving our arrangement of enabling industrial low Earth orbit destinations and expanding the low Earth orbit marketplace.”
The pressurization to failure in the course of the test demonstrated the habitat’s capabilities and provided the firms with serious records supporting NASA’s inflatable softgoods certification pointers, which suggest a progression of checks to maintain in thoughts these materials in relevant operational environments and jam the failure modes.
Demonstrating the habitat’s skill to meet the instructed direct of security by beefy-scale final burst force sorting out is one in all the principle structural requirements on a delicate goods article, such as Sierra Situation’s LIFE habitat, in quest of flight certification.
Sooner than this contemporary test, Sierra Situation conducted its first beefy-scale final burst force test on the LIFE habitat at Marshall in December 2023. Additionally, Sierra Situation beforehand done subscale checks, first at NASA’s Johnson Situation Heart and then at Marshall as half of ongoing pattern and sorting out of inflatable habitation architecture.
NASA supports the have and pattern of multiple industrial living stations, in conjunction with Orbital Reef, by funded and unfunded agreements. The most in trend have and pattern allotment will doubtless be followed by the procurement of products and services from one or more firms.
NASA’s arrangement is to attain a solid economy in low Earth orbit where the company have to buy products and services as one in all many customers to meet its science and analysis dreams in microgravity. NASA’s industrial formulation for low Earth orbit will provide the authorities with legit and proper products and services at a lower price, enabling the company to point of curiosity on Artemis missions to the Moon in preparation for Mars while also continuing to make utilize of low Earth orbit as a coaching and proving ground for those deep living missions.

In discovering out records restful from NASA’s DART (Double Asteroid Redirection Test) mission, which in 2022 sent a spacecraft to intentionally collide with the asteroid moonlet Dimorphos, the mission’s science group has found original records on the origins of the arrangement binary asteroid machine and why the DART spacecraft became as soon as so effective in transferring Dimorphos’ orbit.
In five no longer too prolonged within the past published papers in Nature Communications, the group explored the geology of the binary asteroid machine, comprising moonlet Dimorphos and dad or mum asteroid Didymos, to characterize its beginning and evolution and constrain its physical traits.
“These findings give us original insights into the solutions that asteroids can trade over time,” stated Thomas Statler, lead scientist for Solar Intention Little Bodies at NASA Headquarters. “Right here’s valuable no longer correct for working out the attain-Earth objects which will doubtless be the purpose of curiosity of planetary defense, however also for our skill to read the historical previous of our Solar Intention from these remnants of planet formation. Right here’s correct half of the wealth of contemporary recordsdata we’ve won from DART.”
Olivier Barnouin and Ronald-Louis Ballouz of Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, led a paper that analyzed the geology of every asteroids and drew conclusions about their surface materials and interior properties. From pictures captured by DART and its accompanying LICIACube cubesat – contributed by the Italian Situation Company (ASI), the group observed the smaller asteroid Dimorphos’ topography, which featured boulders of varying sizes. When put next, the upper asteroid Didymos became as soon as smoother at lower elevations, though rocky at better elevations, with more craters than Dimorphos. The authors inferred that Dimorphos doubtless spun off from Didymos in a gargantuan mass shedding tournament.
There are pure processes that can accelerate up the spins of small asteroids, and there may per chance be rising evidence that these processes will doubtless be accountable for re-shaping these our bodies or even forcing cloth to be spun off their surfaces.
Diagnosis suggested that every Didymos and Dimorphos hold feeble surface traits, which led the group to posit that Didymos has a surface age 40–130 times older than Dimorphos, with the broken-down estimated to be 12.5 million years and the latter lower than 300,000 years feeble. The low surface power of Dimorphos doubtless contributed to DART’s fundamental influence on its orbit.
“The pictures and records that DART restful at the Didymos machine provided a various substitute for a shut-up geological peek of a attain-Earth asteroid binary machine,” stated Barnouin. “From these pictures on my own, we were able to infer a gargantuan deal of records on geophysical properties of every Didymos and Dimorphos and catch higher our working out on the formation of those two asteroids. We also better mark why DART became as soon as so effective in transferring Dimorphos.”
Maurizio Pajola, of the National Institute for Astrophysics (INAF) in Rome, and co-authors led a paper comparing the shapes and sizes of the a range of boulders and their distribution patterns on the two asteroids’ surfaces. They distinct the physical traits of Dimorphos screen it formed in phases, doubtless of cloth inherited from its dad or mum asteroid Didymos. That conclusion reinforces the existing theory that some binary asteroid systems come up from shed remnants of the next fundamental asteroid amassing into a original asteroid moonlet.
Alice Lucchetti, also of INAF, and colleagues found that thermal fatigue – the boring weakening and cracking of a fabric brought about by warmth – may per chance well presumably all of the sudden ruin up boulders on the surface of Dimorphos, generating surface lines and altering the physical traits of this form of asteroid more hasty than beforehand thought. The DART mission became as soon as doubtless the principle statement of this kind of phenomenon on this form of asteroid.
Supervised by researcher Naomi Murdoch of ISAE-SUPAERO in Toulouse, France, and colleagues, a paper led by students Jeanne Bigot and Pauline Lombardo distinct Didymos’ bearing skill – the surface’s skill to enhance utilized loads – to be at the very least 1,000 times lower than that of dry sand on Earth or lunar soil. Right here’s thought about an valuable parameter for working out and predicting the response of a surface, in conjunction with for the applications of displacing an asteroid.
Colas Robin, also of ISAE-SUPAERO, and co-authors analyzed the surface boulders on Dimorphos, comparing them with those on various rubble pile asteroids, in conjunction with Itokawa, Ryugu, and Bennu. The researchers found the boulders shared identical traits, suggesting all most of those asteroids formed and evolved in a identical trend. The group also illustrious that the elongated nature of the boulders spherical the DART influence location implies that they were doubtless formed by influence processing.
These most in trend findings kind a more strong overview of the origins of the Didymos machine and add to the working out of how such planetary our bodies were formed. As ESA’s (European Situation Company) Hera mission prepares to revisit DART’s collision location in 2026 to extra analyze the aftermath of the principle-ever planetary defense test, this analysis presents a chain of checks for what Hera will salvage and contributes to most in trend and future exploration missions while bolstering planetary defense capabilities.
Johns Hopkins APL managed the DART mission for NASA’s Planetary Protection Coordination Position of enterprise as a mission of the company’s Planetary Missions Program Position of enterprise, which is at NASA’s Marshall Situation Flight Heart. NASA provided enhance for the mission from quite a bit of centers, in conjunction with the Jet Propulsion Laboratory, Goddard Situation Flight Heart, Johnson Situation Heart, Glenn Research Heart, and Langley Research Heart.
In October 2022, astronomers were panicked by what became as soon as hasty dubbed the BOAT — the brightest-of-all-time gamma-ray burst (GRB). Now a world science group reviews that records from NASA’s Fermi Gamma-ray Situation Telescope shows a feature never viewed sooner than.
“About a minutes after the BOAT erupted, Fermi’s Gamma-ray Burst Video show recorded a regular energy high that caught our consideration,” stated lead researcher Maria Edvige Ravasio at Radboud College in Nijmegen, Netherlands, and affiliated with Brera Observatory, half of INAF (the Italian National Institute of Astrophysics) in Merate, Italy. “When I first saw that signal, it gave me goosebumps. Our prognosis since then shows it to be the principle high-self belief emission line ever viewed in 50 years of discovering out GRBs.”
A paper about the discovery looks within the July 26 edition of the journal Science.
When matter interacts with mild, the energy will also be absorbed and reemitted in attribute solutions. These interactions can brighten or gloomy dispute colors (or energies), producing key points visible when the sunshine is unfold out, rainbow-adore, in a spectrum. These points can suppose a wealth of records, such because the chemical substances inquisitive about the interaction. At better energies, spectral points can repeat dispute particle processes, such as matter and antimatter annihilating to provide gamma rays.
“Whereas some old analysis hold reported skill evidence for absorption and emission points in various GRBs, subsequent scrutiny printed that every body in all those may per chance well presumably correct be statistical fluctuations. What we assign a query to within the BOAT is various,” stated coauthor Om Sharan Salafia at INAF-Brera Observatory in Milan, Italy. “We’ve distinct that the percentages this selection is correct a noise fluctuation are lower than one probability in half a thousand million.”
GRBs are doubtlessly the most highly effective explosions within the cosmos and emit copious quantities of gamma rays, the most realistic-energy form of sunshine. The most typical form occurs when the core of a massive well-known person exhausts its gasoline, collapses, and forms a all of the sudden spinning unlit hole. Topic falling into the unlit hole powers oppositely directed particle jets that blast by the well-known person’s outer layers at on the discipline of the accelerate of sunshine. We detect GRBs when one in all those jets points practically without lengthen toward Earth.
The BOAT, formally is named GRB 221009A, erupted Oct. 9, 2022, and promptly saturated quite a bit of the gamma-ray detectors in orbit, in conjunction with those on Fermi. This prevented them from measuring doubtlessly the most intense half of the blast. Reconstructed observations, coupled with statistical arguments, suggest the BOAT, if half of the identical inhabitants as beforehand detected GRBs, became as soon as doubtless the brightest burst to look in Earth’s skies in 10,000 years.
The putative emission line looks practically 5 minutes after the burst became as soon as detected and successfully after it had dimmed ample to end saturation outcomes for Fermi. The road endured for at the very least 40 seconds, and the emission reached a high energy of about 12 MeV (million electron volts). For comparison, the energy of visible mild ranges from 2 to three electron volts.
So what produced this spectral feature? The group thinks the most likely supply is the annihilation of electrons and their antimatter counterparts, positrons.
“When an electron and a positron collide, they annihilate, producing a pair of gamma rays with an energy of 0.511 MeV,” stated coauthor Gor Oganesyan at Gran Sasso Science Institute and Gran Sasso National Laboratory in L’Aquila, Italy. “On fable of we’re taking a salvage out about into the jet, where matter is transferring at attain mild accelerate, this emission becomes greatly blueshifted and pushed toward a lot better energies.”
If this interpretation is correct, to provide an emission line peaking at 12 MeV, the annihilating particles needed to hold been transferring toward us at about ninety nine.9% the accelerate of sunshine.
“After a protracted time of discovering out these unparalleled cosmic explosions, we aloof don’t mark the valuable points of how these jets work,” illustrious Elizabeth Hays, the Fermi mission scientist at NASA’s Goddard Situation Flight Heart. “Discovering clues adore this outstanding emission line may per chance well presumably lend a hand scientists compare this indecent atmosphere more deeply.”
The Fermi Gamma-ray Situation Telescope is an astrophysics and particle physics partnership managed by Goddard. Fermi became as soon as developed in collaboration with the U.S. Division of Power, with valuable contributions from academic establishments and companions in France, Germany, Italy, Japan, Sweden, and the United States.
NASA’s Marshall Situation Flight Heart is accountable for one in all the instruments on the Fermi Gamma-ray Situation Telescope – the Gamma-ray Burst Video show, or GBM. The GBM analysis gamma-ray bursts, doubtlessly the most highly effective explosions within the universe, as successfully as various flashes of gamma rays. The GBM sees these bursts across your entire sky, and scientists are the utilization of its observations to be taught more about the universe.
