  1. 1 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Donald Figer Rochester Institute of Technology The objective of this grant is to investigate methods to reduce and mitigate the effects of radiation damage on single-photon counting and photon number resolving optical imaging detectors. To accomplish this, professor Finger and his team will develop computational models of these devices as well as test a number of commercially available designs. They will attempt to minimize the transient effects of radiation by exploring innovative new ways to read and process their data, develop new ways of driving and operating them, and use analysis of output data to pinpoint and understand radiation related damage mechanisms. The team will also work to extend the operating rage of these devices to infrared wavelengths, an important capability for many NASA applications.

  2. 1 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Karl Berggren Massachusetts Institute of Technology Superconducting nanowire single-photon detectors (SNSPDs) are a promising new ultra-sensitive and low-noise detectors for applications ranging from deep-space exploration to ultrafast space-based optical quantum communication networks. Their susceptibility to damage from the high-radiation environments found in space is not yet understood. Professor Berggren and his team will investigate radiation damage to SNSPDs in their lab by bombarding them 30keV helium ions at irradiated doses far exceeding the expected levels in space. Using the results of these experiments and complementary modeling efforts the team will also investigate mitigation strategies.

  4. 4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) GSFC summer interns NASA is celebrating National Mentoring Month by recognizing the importance of mentors to students and young professionals whose careers are beginning to take off. Mentors help their mentees gain real-world experiences, make valuable connections, and find the types of roles best suited to their strengths and skills. To learn more about early career takeaways, we spoke to three NASA mentors: Renita Fincke, NASA biomedical research projects engineer at Johnson Space Center in Houston; Wade Sisler, executive producer at NASA’s Goddard Space Flight Center in Greenbelt, Maryland; and Kyle Ellis, a project manager in the Aeronautics Research Directorate at NASA’s Langley Research Center in Hampton, Virginia. Below, they share their advice for students and graduates entering the workforce and expand on how to make the most of a mentor/mentee relationship – whether here at NASA or in any other organization. Renita Fincke, NASA biomedical research projects engineer at Johnson Space Center in Houston. Work hard and carry yourself professionally. If you fully commit to excelling in your role, you’ll be better prepared to take advantage of unexpected opportunities or adjust to changing circumstances. “Give it your all,” Fincke said. “In my journey, I’ve discovered that boosting your career involves a relentless pursuit of knowledge, adapting to changes, and being ready to try for exciting opportunities when the timing is just right.” While you’re putting in a lot of effort toward your high-level goals, don’t lose sight of seemingly small details. “Lean in, be punctual, be present, communicate like a pro, and get your work in on time,” Sisler said. “Your mentor will notice. Your entire office will notice.” Be your own advocate. Concentrate on how you communicate. Telling your story in a way that resonates with your audience enables them to understand and see the value in your work. “Learn to identify who your stakeholders are and answer the question, ‘Why should they care?’” Ellis said. “Being able to tell a clear, succinct story about what you do and why is the key to improving countless things: interest, support, awareness, etc. Don’t take the power of communication for granted.” Wade Sisler, executive producer at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Be resilient. Challenges and failures are inevitable, so don’t give up! “The path to success is rarely linear, and the ability to adapt is a strength,” Fincke said. “Embrace the mindset that errors are opportunities for learning, growth, and necessary pivots, so do not fear failure; let it be a catalyst for resilience.” Ellis recalled that as a student, he spent a lot of time unnecessarily fearing what others would think if he tried something new without knowing for sure he’d get it right. “What I learned is that failure is common when you’re exploring possibilities,” Ellis said. “And it often teaches us more in a shorter period than the success we experience. Kyle Ellis, a project manager in the Aeronautics Research Directorate at NASA’s Langley Research Center in Hampton, Virginia. Network and ask questions. Work with a mentor to outline your tasks and goals, and don’t be self-conscious about discussing your most ambitious longer-term career objectives. “The most successful interns in our office are often the most inquisitive ones,” Sisler said. “Find out what the people in your office do and how they fit into the organization. Tell as many people as you can your story, ask how they came to NASA, and ask them for their insights and advice.” Ellis emphasized that NASA is filled with experts who are happy to share their wisdom with students and young professionals. “If they sense the spark in you, they’ll most certainly help you along your career and connect you with more like-minded people who are solving some of the most important problems in and out of this world,” Ellis said. The support and guidance of an encouraging mentor can make a tremendous difference in a student’s career growth and personal development – and it’s a rewarding experience for mentors, too. “Pick up a mentee in your first or second year in a new role,” Ellis said. “It’s amazing what you learn from someone who is learning from you.” Want an opportunity to work with one of NASA’s amazing mentors?

  5. 3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Artist’s rendering of the Optical Communications System bringing laser communications capabilities to the Moon aboard NASA’s Orion spacecraft during Artemis II.Credit: NASA NASA is working with private industry partners and small businesses under Artemis to produce scalable, affordable, and advanced laser communications systems that could enable greater exploration and discovery beyond Earth for the benefit of all. Laser, or optical, communications provide missions with increased data rates – meaning that missions using laser technology can send and receive more information in a single transmission compared with those using traditional radio waves. When a spacecraft uses laser communications to send information, infrared light packs the data into tighter waves so ground stations on Earth can receive more data at once. Laser communications systems can provide 10 to 100 times higher data rates than the radio systems used by space missions today. As science instruments evolve to capture high-definition data, missions will need expedited ways to transmit information to Earth. It would take roughly nine weeks to transmit a complete map of Mars back to Earth with current radio frequency systems. With lasers, it would only take about nine days. Advancing Laser Technologies Through a small business collaboration, NASA’s Space Communications and Navigation (SCaN) Program funded the successful development of a new piece of laser technology. Developed by Fibertek Inc., the Basestation Optical Laser Terminal is a four-channel laser unit that could enable the transmission of high-power communications to the Moon during the Artemis II flight test. Artemis II will send a crew of four astronauts on a journey around the Moon and bring them back safely, paving the way for future long-term human exploration missions to the lunar surface, and eventually Mars. Known as the Orion Artemis II Optical Communications System, the Artemis II demonstration will use laser communications to transmit high-resolution images and video of the lunar region to two ground stations. One of the two ground stations, located at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, is the Low-Cost Optical Terminal. The Low-Cost Optical Terminal at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, uses commercial off-the-shelf or slightly modified hardware to reduce the expense of implementing laser communications technology.Credit: NASA In September 2023, Fibertek’s technology was integrated into NASA’s low-cost terminal ground station and successfully tested. NASA’s Low-Cost Optical Terminal is a telescope around 27 inches in diameter that is made of mostly commercial off-the-shelf parts. Using commercial components is more cost-effective than developing custom hardware and can also make an architecture scalable for replication. The Low-Cost Optical Terminal will serve as a template for future ground stations. “Laser communications, focusing on direct-to-Earth links, is a maturing technology that is essential for NASA to meet its future communications capacity and navigation needs. As we mature any technology, establishing and supporting a healthy domestic supply chain is vital,” said Dr. Jason Mitchell, director of SCaN’s Advanced Communications and Navigation Technologies Division at NASA Headquarters in Washington. “American small businesses play a key role in that chain, and our engagement with Fibertek Inc. is an example of this process.” NASA’s Glenn Research Center in Cleveland and NASA’s Small Business Innovation Research Program funded the development of the Basestation Optical Laser Terminal. Through America’s Seed Fund, NASA provides small businesses with early-stage federal funding for innovative technologies to advance agency missions. “NASA’s investment in the development of this technology is a win-win-win for the agency and Fibertek, as well as any other future system integrators or developers that want to use laser communications technology,” said Nang Pham, SCaN small business project manager at NASA Glenn. As NASA prepares to send human’s back to the Moon for the first time in 50 years, new laser technologies will enable more efficient laser communications systems, expanding humanity’s knowledge of our Moon and what lies beyond.

  6. To replace the cargo and crew transportation services to and from the International Space Station following the retirement of the space shuttle in 2011, the United States developed a novel approach to procure those services from American commercial entities. On Jan. 9, 2014, Orbital Sciences Corporation, one of two companies selected initially to provide cargo transportation services, launched the first operational mission of its Cygnus spacecraft. During its one-month stay at the space station, the onboard Expedition 38 crew unloaded its cargo and then filled it with trash and unneeded equipment before releasing it for a destructive reentry. The novel approach of the government procuring services provided by private companies opened a new chapter in human space exploration. Timeline of the first phase of Commercial Orbital Transportation Services (COTS) activities. On Jan. 14, 2004, President George W. Bush announced the Vision for Space Exploration (VSE). In addition to proposing a return to the Moon, the VSE saw the retirement of the space shuttle after completing space station assembly. The VSE encouraged NASA to acquire commercial cargo services to the space station as soon as practical, and NASA Administrator Michael D. Griffin established the Commercial Crew and Cargo Program Office (C3PO) in November 2005. The program inaugurated a new business model for the space agency that instead of traditional procurement contracts with private enterprise to deliver hardware and services, NASA now relied on the companies investing their own capital to develop the needed spacecraft and rockets. The agency then purchased the transportation services from the companies. The C3PO devised a two-phase process to develop cargo resupply services to the space station – the Commercial Orbital Transportation System (COTS) program for commercial entities to develop and demonstrate reliable commercial services followed by the Commercial Resupply Services (CRS) program to actually deliver cargo to the space station. On Aug. 18, 2006, NASA announced that Space Exploration Corporation (SpaceX) of Hawthorne, California, and Oklahoma City, Oklahoma-based Rocketplane Kistler (RpK) had won the first round of the COTS competition and signed Space Act Agreements (SAAs) with the two companies. In October 2007, NASA terminated the agreement with RpK since the company hadn’t raised enough capital. Following a second round of competitions, NASA selected and signed a SAA with Orbital Sciences Corporation (Orbital) of Dulles, Virginia, on Feb. 19, 2008. Left: Workers integrate the Cygnus mass simulator with its Antares launch vehicle. Right: First launch of an Antares rocket in 2013, carrying a Cygnus mass simulator. Italian aerospace company Thales Alenia Space built Orbital’s Cygnus cargo vehicle, relying on its experience building the European Space Agency’s Columbus research module and the Multi-Purpose Logistics Modules for the space station. Orbital developed the two-stage Antares rocket to launch the Cygnus spacecraft. On Dec. 23, 2008, NASA announced the award of the first CRS contracts to SpaceX for 12 space station resupply missions using its Dragon spacecraft and to Orbital for eight missions, in 2015 adding eight more Dragon and three more Cygnus flights. On Jan. 14, 2016, a second CRS-2 contract not only guaranteed at least six more SpaceX and Orbital missions but also added a third contractor, Sparks, Nevada-based Sierra Nevada Corporation to provide at least six flights of a cargo version of their Dream Chaser reusable space plane. Orbital launched the first test flight of its Antares rocket from the Mid-Atlantic Regional Spaceport on Wallops Island, Virginia, on April 21, 2013, with a test payload to simulate the mass of a Cygnus spacecraft. The mission’s objectives did not include approaching the space station and the mass simulator burned up on reentry on May 10. Left: Liftoff of the Antares rocket carrying the Cygnus Demo 1 mission. Middle: Cygnus Demo spacecraft grappled by Canadarm2 prior to berthing on the space station. Right: Expedition 37 crew member Luca S. Parmitano of the European Space Agency inside the Cygnus spacecraft during its Demo mission to the space station. Orbital carried out a single demonstration mission, designated Cygnus Demo 1, launching on Sep. 18, 2013. The company began a tradition of naming their spacecraft after deceased astronauts or other aerospace notables, christening this first one the G. David Low after the former astronaut and Orbital employee who died in 2008. Orbital executive and Low’s fellow Class of 1984 astronaut Frank L. Culbertson said during a preflight press conference, “We were very proud to name [it] the G. David Low.” Eleven days after its launch, Expedition 37 crew member Luca S. Parmitano from the European Space Agency grappled the spacecraft with the Canadarm2 remote manipulator system and berthed it to the station’s Node 2 Harmony module’s nadir or Earth facing port. The crew unloaded the 1,543 pounds of supplies that it brought and on Oct. 22 unberthed it, loaded with 2,850 pounds of cargo for disposal. The next day, Cygnus fired its engine to begin the fiery reentry over the Pacific Ocean. The mission completed Orbital’s flight certification for its cargo vehicle. Left: Liftoff of the first operational Cygnus cargo resupply mission. Middle: The space station’s Canadarm2 robotic arm about to capture the first operational Cygnus spacecraft named SS C. Gordon Fullerton. Right: The first Enhanced Cygnus arriving at the space station in 2015; compare against the smaller standard Cygnus. The mission patch for Orbital’s first operational cargo resupply mission to the space station. The first operational Cygnus mission, designated Orb-1, got underway on Jan. 9, 2014. The spacecraft named after NASA astronaut C. Gordon Fullerton, who died the previous year, arrived at the space station three days later. Expedition 38 crew member NASA astronaut Michael S. Hopkins used Canadarm2 to grapple and berth it to the Harmony module. The onboard crew unloaded the 2,780 pounds of supplies that the spacecraft brought to the station and unberthed it on Feb. 18. It disposed of 3,240 pounds of trash and other unneeded cargo. To date, 19 Cygnus spacecraft have lofted more than 64 tons of logistics to the space station, with only one launch failure, the Orb-3 mission in October 2014. This launch failure and one with SpaceX in June 2015 highlighted the wisdom of the decision to use two separate and independent systems to launch cargo to the space station. Beginning in late 2015, Orbital introduced an Enhanced Cygnus with a 50% increase in internal volume to carry more cargo. In addition to upgrading its spacecraft and rocket, Orbital underwent some corporate restructuring over the years, first merging with Alliant Technologies in 2015 to form Orbital ATK. In 2018 Northrup Grumman acquired Orbital ATK to form Northrup Grumman Innovation Systems. Upgrades to the space station itself, such as opening up a second berthing port on the Unity module in 2015 allowed two cargo vehicles to be docked at the same time, with a third port available in 2019 for SpaceX crew and cargo vehicles to dock directly at the station without the need for astronauts to use Canadarm2 to grapple and berth them. Beginning in 2024, a fourth port will allow four cargo and crew vehicles to remain at the station simultaneously.

  8. 5 min read Hubble Finds Weird Home of Farthest Fast Radio Burst A NASA Hubble Space Telescope image of the host galaxy of an exceptionally powerful fast radio burst, FRB 20220610A. Hubble’s sensitivity and sharpness reveals a compact group of multiple galaxies that may be in the process of merging. They existed when the universe was only 5 billion years old. FRB 20220610A was first detected on June 10, 2022, by the Australian Square Kilometer Array Pathfinder (ASKAP) radio telescope in Western Australia. The European Southern Observatory’s Very Large Telescope in Chile confirmed that the FRB came from a distant place. NASA, ESA, STScI, Alexa Gordon (Northwestern) Astronomers using NASA’s Hubble Space Telescope have found a rare event in an oddball place. It’s called a fast radio burst (FRB), a fleeting blast of energy that can – for a few milliseconds – outshine an entire galaxy. Hundreds of FRBs have been detected over the past few years. They pop off all over the sky like camera flashes at a stadium event, but the sources behind these intense bursts of radiation remain uncertain. This new FRB is particularly weird because it erupted halfway across the universe, making it the farthest and most powerful example detected to date. And if that’s not strange enough, it just got weirder based on the follow-up Hubble observations made after its discovery. The FRB flashed in what seems like an unlikely place: a collection of galaxies that existed when the universe was only 5 billion years old. The large majority of previous FRBs have been found in isolated galaxies. FRB 20220610A was first detected on June 10, 2022, by the Australian Square Kilometer Array Pathfinder (ASKAP) radio telescope in Western Australia. The European Southern Observatory’s Very Large Telescope in Chile confirmed that the FRB came from a distant place. The FRB was four times more energetic than closer FRBs. “It required Hubble’s keen sharpness and sensitivity to pinpoint exactly where the FRB came from,” said lead author Alexa Gordon of Northwestern University in Evanston, Illinois. “Without Hubble’s imaging, it would still remain a mystery as to whether this was originating from one monolithic galaxy or from some type of interacting system. It’s these types of environments – these weird ones – that are driving us toward better understanding the mystery of FRBs.” Hubble’s crisp images suggest this FRB originated in an environment where there may be as many as seven galaxies on a possible path to merging, which would also be very significant, researchers say. “We are ultimately trying to answer the questions: What causes them? What are their progenitors and what are their origins? The Hubble observations provide a spectacular view of the surprising types of environments that give rise to these mysterious events,” said co-investigator Wen-fai Fong, also of Northwestern University. Though astronomers do not have a consensus on the possible mechanism behind this extraordinary phenomenon, it’s generally thought that FRBs must involve some sort of compact object, like a black hole or neutron star. One extreme type of neutron star is called a magnetar – the most intensely magnetic type of neutron star in the universe. It has a magnetic field that is so strong that, if a magnetar were located halfway between Earth and the Moon, it would erase the magnetic strip on everyone’s credit card in the world. Much worse yet, if an astronaut traveled within a few hundred miles of the magnetar, they would effectively be dissolved, because every atom in their body would be disrupted. Possible mechanisms involve some kind of jarring starquake, or alternatively, an explosion caused when a magnetar’s twisting magnetic field lines snap and reconnect. A similar phenomenon happens on the Sun, causing solar flares, but a magnetar’s field is a trillion times stronger than the Sun’s magnetosphere. The snapping would generate an FRB’s flash, or might make a shock wave that incinerates surrounding dust and heats gas into a plasma. There could be several flavors of magnetars. In one case, it could be an exploding object orbiting a black hole surrounded by a disk of material. Another alternative is a pair of orbiting neutron stars whose magnetospheres periodically interact, creating a cavity where eruptions can take place. It’s estimated that magnetars are active for about 10,000 years before settling down, so they would be expected to be found where a firestorm of star birth is taking place. But this doesn’t seem to be the case for all magnetars. In the near future, FRB experiments will increase their sensitivity, leading to an unprecedented rate in the number of FRBs detected at these distances. Hubble will play a crucial role in characterizing the environments in which these FRBs occur. Astronomers will soon learn just how special the environment of this FRB was. “We just need to keep finding more of these FRBs, both nearby and far away, and in all these different types of environments,” said Gordon. The results are being presented at the 243rd meeting of the American Astronomical Society in New Orleans, Louisiana. The Hubble Space Telescope is a project of international cooperation between NASA and ESA. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope. The Space Telescope Science Institute (STScI) in Baltimore, Maryland, conducts Hubble and Webb science operations.

  9. Los miembros de la tripulación del Artemis II (de izquierda a derecha) Jeremy Hansen, astronauta de la CSA (Agencia Espacial Canadiense), y Christina Koch, Victor Glover y Reid Wiseman, astronautas de la NASA, parten del cuartel de tripulación de astronautas en el edificio de operaciones y control Neil Armstrong hacia los vehículos de transporte de la tripulación de Artemis antes de desplazarse a la plataforma de lanzamiento 39B como parte de una prueba integrada de los sistemas de tierra en el Centro Espacial Kennedy en Florida el miércoles 20 de septiembre, para poner a prueba la cronología de la tripulación para el día del lanzamiento.NASA La NASA anunció el martes cambios en las próximas misiones Artemis, que sentarán las bases para la exploración científica a largo plazo de la Luna, el aterrizaje de la primera mujer y la primera persona no blanca en la superficie lunar, y la preparación de expediciones con seres humanos a Marte en beneficio de todos. Para llevar a cabo estas misiones de forma segura, los dirigentes de la agencia han ajustado los calendarios de Artemis II y Artemis III para que los equipos técnicos puedan superar los retos asociados a los primeros desarrollos, operaciones e integración. El objetivo de la NASA es ahora septiembre de 2025 para Artemis II, la primera misión Artemis tripulada alrededor de la Luna, y septiembre de 2026 para Artemis III, la cual se prevé que aterrice con los primeros astronautas cerca del Polo Sur lunar. Artemis IV, la primera misión a la estación espacial lunar Gateway, sigue prevista para 2028. “Estamos regresando a la Luna como nunca antes lo habíamos hecho, y la seguridad de nuestros astronautas es la máxima prioridad de la NASA mientras nos preparamos para futuras misiones Artemis”, dijo el administrador de la NASA, Bill Nelson. “Hemos aprendido mucho desde Artemis I, y el éxito de estas primeras misiones depende de nuestras asociaciones comerciales e internacionales para ampliar nuestro alcance y comprensión del lugar de la humanidad en nuestro sistema solar. Artemis representa lo que podemos lograr como nación y como coalición mundial. Cuando nos proponemos lograr lo difícil, juntos podemos conseguir lo grandioso”. Garantizar la seguridad de la tripulación es el principal motivo de los cambios en el calendario de Artemis II. Como primera prueba de vuelo Artemis con tripulación a bordo de la nave espacial Orion, la misión pondrá a prueba sistemas críticos de control medioambiental y de soporte vital necesarios para sustentar a los astronautas. Las pruebas de la NASA para calificar los componentes para mantener a la tripulación segura y garantizar el éxito de la misión han revelado problemas que requieren tiempo adicional para ser resueltos. Los equipos técnicos están solucionando un asunto relacionado con la batería y abordando retos con un componente del circuito responsable de la ventilación del aire y el control de la temperatura. Se espera que la investigación de la NASA sobre la pérdida inesperada de trozos de capa de carbón del escudo térmico de la nave espacial durante Artemis I concluya esta primavera boreal. Los equipos técnicos han adoptado un enfoque metódico para entender el problema, que incluye un amplio muestreo del escudo térmico, pruebas y revisión de los datos de los sensores y las imágenes. El nuevo calendario para Artemis III se alinea con el calendario actualizado para Artemis II, garantiza que la agencia pueda incorporar las lecciones aprendidas de Artemis II en la próxima misión y reconoce los retos de desarrollo que han experimentado los socios industriales de la NASA. Dado que cada misión Artemis tripulada aumenta la complejidad y añade pruebas de vuelo para nuevos sistemas, el calendario ajustado proporcionará a los proveedores que desarrollan nuevas capacidades (SpaceX para el sistema de aterrizaje humano y Axiom Space para los trajes espaciales de nueva generación) tiempo adicional para las pruebas y cualquier refinamiento antes de la misión. “Estamos dejando que el hardware nos dé información para que la seguridad de la tripulación guíe nuestra toma de decisiones. Utilizaremos la prueba de vuelo de Artemis II, y cada uno de los vuelos siguientes, para reducir el riesgo de futuras misiones a la Luna”, declaró Catherine Koerner, administradora asociada de la Dirección de Misiones de Desarrollo de Sistemas de Exploración de la sede central de la NASA en Washington. “Estamos resolviendo los retos asociados con las capacidades y operaciones nuevas, y estamos más cerca que nunca de establecer una exploración sostenida del vecino más cercano de la Tierra mediante Artemis”. Además de las actualizaciones del calendario para Artemis II y III, la NASA está reexaminando el calendario para el lanzamiento de los primeros elementos integrados de Gateway, previsto anteriormente para octubre de 2025, con el fin de proporcionar tiempo de desarrollo adicional y alinear mejor ese lanzamiento con la misión Artemis IV en 2028. La NASA también ha comunicado que ha pedido a los dos proveedores del sistema de aterrizaje para seres humanos de Artemis (SpaceX y Blue Origin) que, como parte de sus contratos actuales, empiecen a aplicar los conocimientos adquiridos en el desarrollo de sus sistemas a futuras variaciones para poder transportar grandes cargamentos en misiones posteriores. “Artemis es una campaña de exploración a largo plazo para llevar a cabo actividades científicas en la Luna con astronautas y preparar futuras misiones tripuladas a Marte. Eso significa que debemos hacerlo bien a medida que desarrollamos y lanzamos nuestros sistemas fundamentales para que podamos llevar a cabo estas misiones con seguridad”, dijo Amit Kshatriya, administrador adjunto de Desarrollo de Sistemas de Exploración, y gerente de la Oficina del Programa de la Luna a Marte de la NASA en la sede de la agencia. “La seguridad de la tripulación es y seguirá siendo nuestra prioridad número uno”. Los dirigentes de la NASA hicieron hincapié en la importancia de que todos los socios cumplan los plazos para que la agencia pueda maximizar los objetivos de vuelo con el hardware disponible en cada misión. La NASA evalúa periódicamente el progreso y los plazos como parte de la planificación programática integrada para garantizar que la agencia y sus socios puedan cumplir con éxito sus objetivos de exploración de la Luna a Marte. Mediante Artemis, la NASA explorará la Luna más que nunca, aprenderá a vivir y trabajar lejos de nuestro hogar y se preparará para la futura exploración con seres humanos del planeta rojo. El cohete Sistema de Lanzamiento Espacial de la NASA, los sistemas terrestres de exploración y la nave Orion, junto con el sistema de aterrizaje para humanos, los trajes espaciales de nueva generación, la estación espacial lunar Gateway y los futuros vehículos exploradores son la base de la NASA para la exploración del espacio profundo.

The centerpiece of NASA's Quesst mission, the agency and Lockheed Martin will formally unveil the aircraft to the public on Friday, Jan. 12. Credits: NASA Lee esta historia en español aquí. NASA’s X-59 aircraft is heading out of the hangar – preparing to embark on the first phase of its mission to fly faster than the speed of sound without generating a loud sonic boom. Leadership from NASA and prime contractor Lockheed Martin will officially unveil the fully completed and freshly painted X-59 to the world during a rollout ceremony Friday, Jan. 12 at 4 p.m., EST. NASA TV will broadcast the event live from Lockheed Martin’s Skunk Works facility in Palmdale, California, where the aircraft was assembled. “This is the big reveal,” said Catherine Bahm, manager of NASA’s Low Boom Flight Demonstrator project, who is overseeing the development and build of the X-59. “The rollout is a huge milestone toward achieving the overarching goal of the Quesst mission to quiet the sonic boom.” Quesst is NASA’s mission through which the X-59 will demonstrate its quiet supersonic capabilities. NASA will fly the aircraft over selected U.S. communities and then survey what people on the ground hear when it flies overhead. The agency will share data on these reactions to the quieter sonic “thumps” with regulators, who could then consider rules that currently ban commercial supersonic flight over land because of noise concerns. Watch this two-minute video to experience a visual overview of NASA’s Quesst mission featuring the X-59 experimental aircraft. Tradition of Rollout So, what is an aircraft rollout? And why is it significant to NASA, industry stakeholders, and the team of aeronautical innovators who built the X-59? Conceiving, designing, building, and testing a new airplane takes years of meticulous, highly detailed work. Every new design helps innovate a new way to fly – especially in the case of X-planes, whose very mission is to continue pushing the boundaries of what’s possible. Unveiling the X-59 to the world represents not just the aircraft’s technical achievements, but also the future of flight, and the spirit of aeronautics research itself. For the team, some of whom have worked on the aircraft since the first component was created, the reveal of the X-59 will be a very special moment. CATHERINE BAHM NASA Project Manager In the past, aircraft and spacecraft built for and used by NASA have had rollout ceremonies ranging in scope and meaning. In 1959, for example, the first X-15 rocket-powered aircraft rolled out to great fanfare to an audience including project leadership, the aircraft’s pilots, and then-Vice President Richard Nixon. The aircraft represented the future of winged spaceflight and hypersonic flight. It went on to carry American pilots into space onboard a winged vehicle for the first time, as well as set the record for the fastest speed a human has travelled on an airplane, which still stands to this day. Crowds gather on Oct. 15, 1958, to admire the first X-15 rocket plane after its rollout from the North American Aviation plant in Los Angeles. One of NASA’s most historic aircraft, it flew 199 missions between 1959 and 1968 during a program that included NASA, the U.S. Air Force, and the U.S. Navy. Another famous NASA rollout is that of space shuttle Enterprise in 1976 with the cast of Star Trek: The Original Series, and the show’s creator, Gene Roddenberry, in attendance. The Enterprise, so named for the fictional starship of the 1960s television series, proved the shuttle orbiter could descend and land like an airplane following reentry from space. The vehicle paved the way for the Space Shuttle Program to proceed with spaceflight. NASA officials and representatives from the TV show Star Trek, including creator Gene Roddenberry, were on hand for Enterprise’s rollout from its Rockwell factory in Palmdale, California, on Sept. 17, 1976.NASA Culmination of Efforts In the case of the X-59, the rollout ceremony provides a glimpse of a potential new era of high-speed commercial flight over land – a quiet one. Fifty years ago, the United States prohibited commercial supersonic flight over land because of concerns about the noise generated by sonic booms. Today, however, Quesst’s technology could reduce this noise dramatically. The mission aims to gather data from the X-59 that could help regulators adjust the ban, basing revised rules on noise levels instead of speed. “The idea of lifting the ban on supersonic flight over land is really exciting,” Bahm said. “And that’s the future the X-59 could enable.” The rollout also represents something closer to the ground – the achievement of the hardworking, dedicated team who took the aircraft from imagination to reality. For them, the rollout celebrates the weeks, months, and years spent developing and building the X-59. Watch this 57-second time-lapse video of the X-59’s assembly as it happened between May of 2019 and June of 2021 inside Lockheed Martin’s Skunk Works factory in Palmdale, California. “For the team, some of whom have worked on the aircraft since the first component was created, the reveal of the X-59 will be a very special moment.” Bahm said. “The innovative design of the X-59 leverages decades of work for NASA. We are sharing this achievement with all those who made this possible.” With assembly complete, NASA’s mission to quiet the boom reaches a new chapter. Though there’s still a ways to go, the potential future for commercial supersonic travel is closer than it was before. The Quesst mission team will now continue ground testing before first flight later this year. “Rollout is a major accomplishment, but it also means the next milestone is first flight, and then supersonic flights after that,” Bahm said. “Our eyes are on the mission.” A memorable rollout ceremony in aviation history took place on Sept. 30, 1968, when the first Boeing 747 made its public debut at the company’s Everett assembly plant near Seattle. To commemorate the event, flight attendants representing each of the 26 airlines who had purchased a 747 attended the ceremony.Boeing About the AuthorJohn GouldAeronautics Research Misson Directorate Read More Facebook logo @NASA@NASAaero@NASA_es @NASA@NASAaero@NASA_es Instagram logo @NASA@NASAaero@NASA_es Linkedin logo @NASA Explore More 4 min read NASA Armstrong Builds Model Wing to Help Advance Unique Design Article 1 day ago 2 min read NASA Invites You to X-59 Rollout Watch Party Article 6 days ago 3 min read NASA Flies Drones Autonomously for Air Taxi Research Researchers at NASA’s Langley Research Center in Hampton, Virginia recently flew multiple drones beyond visual… Article 3 weeks ago Keep Exploring Discover More Topics From NASA Aeronautics STEM Science Missions NASA History Aircraft Flown at Armstrong Share Details Last Updated Jan 09, 2024 EditorJim BankeContactMatt Kamletmatthew.r.kamlet@nasa.govSasha Ellissasha.c.ellis@nasa.govKristen Hatfieldkristen.m.hatfield@nasa.govLocationArmstrong Flight Research Center Related TermsAeronauticsAeronautics Research Mission DirectorateCommercial Supersonic TechnologyLow Boom Flight DemonstratorQuesst (X-59)Quesst: The VehicleSupersonic Flight View the full article
  11. 6 Min Read La presentación del X-59 de la NASA personifica la tradición aeronáutica Concepto artístico del silencioso avión supersónico X-59. La pieza central de la misión Questt de la NASA, la agencia y Lockheed Martin presentarán oficialmente al mundo el totalmente terminado y recientemente pintado avion X-59, durante una ceremonia que tendrá lugar el viernes 12 de enero a las 4 de la tarde, hora del Este. Credits: NASA Lee esta historia en inglés aquí. El avión X-59 de la NASA está saliendo del hangar–preparándose para embarcarse en la primera fase de su misión de volar más rápido que la velocidad del sonido sin generar un fuerte estampido sónico. Los directivos de la NASA y el contratista principal Lockheed Martin, presentarán oficialmente al mundo el totalmente terminado y recientemente pintado avion X-59, durante una ceremonia que tendrá lugar el viernes 12 de enero a las 4 de la tarde, hora del Este. Este evento será transmitido en directo por NASA TV desde las instalaciones Skunk Works de Lockheed Martin en Palmdale, California, donde este avión fue ensamblado. “Esta es la gran revelación”, declaró Catherine Bahm, directora del proyecto Low Boom Flight Demonstrator de la NASA, que supervisa el desarrollo y la construcción del X-59. “La presentación es un gran logro hacia el objetivo general de la misión Quesst de reducir el estampido sónico”. Quesst es la misión de la NASA a través de la cual el X-59 demostrará sus capacidades supersónicas silenciosas. La NASA volará la aeronave sobre comunidades estadounidenses seleccionadas y después estudiará lo que la gente sobre tierra firme escucha. La agencia compartirá la información de estas reacciones a los “golpes” sónicos más silenciosos con los organismos reguladores, que podrían considerar las normas que actualmente prohíben los vuelos supersónicos comerciales sobre tierra firme por motivos de ruido. Tradición de la presentación ¿Qué es la presentación de una aeronave? ¿Y por qué es importante para la NASA, el sector industrial y el equipo de innovadores en la aeronáutica que construyeron el X-59? Concebir, diseñar, construír y probar una nueva aeronave conlleva años de trabajo detallado y meticuloso. Cada diseño nuevo contribuye a innovar una nueva forma de volar– especialmente en el caso de los X-Planes, que tienen la misión de continuar sobrepasando los límites de lo posible. La presentación del X-59 al mundo no solamente representa los logros técnicos del avión, sino también el futuro del vuelo y el espíritu de la investigación en la aeronáutica. Para el equipo, algunos de los cuales han trabajado en el avión desde que se creó el primer componente, la presentación del X-59 será un momento muy especial. CATHERINE BAHM NASA Project Manager En el pasado, las aeronaves y naves espaciales construidas y utilizadas por la NASA han tenido ceremonias de presentación de diverso alcance y significado. Por ejemplo, en 1959, el X-15, que fue el primer avión propulsado por cohete, despegó ante una audiencia que incluía a los líderes del proyecto, los pilotos de la aeronave y al Vice presidente Richard Nixon. El avión representaba el futuro de los vuelos espaciales hipersónicos y con alas. Llevó por primera vez a pilotos estadounidenses al espacio a bordo de un vehículo con alas y estableció el récord de velocidad más rápida alcanzada por un humano en un avión, récord que sigue vigente hoy en día. Multitudes se reúnen el 15 de octubre de 1958 para admirar el primer avión cohete X-15 después de su lanzamiento desde la planta de North American Aviation en Los Ángeles. Uno de los aviones más históricos de la NASA, voló 199 misiones entre 1959 y 1968 durante un programa que incluía a la NASA, la Fuerza Aérea de los EE. UU. y la Marina de los EE. UU. Otra presentación famosa de la NASA fue el del transbordador espacial Enterprise en 1976, con la presencia del reparto de Star Trek: la serie original y del creador de la serie, Gene Roddenberry. El Enterprise, llamado así por la nave ficticia de la serie de televisión de los años 60, demostró que el transbordador orbital podía descender y aterrizar como un avión tras su reentrada del espacio. El vehículo marcó el camino para que el Programa del Transbordador Espacial continuara con los vuelos espaciales. Funcionarios de la NASA y representantes del programa de televisión Star Trek, incluido el creador Gene Roddenberry, estuvieron presentes en el lanzamiento de Enterprise desde su fábrica de Rockwell en Palmdale, California, el 17 de septiembre de 1976.NASA Culminación de los esfuerzos En el caso del X-59, la ceremonia de presentación permite vislumbrar una posible nueva era de vuelos comerciales de alta velocidad y silenciosos sobre tierra. Hace cincuenta años, Estados Unidos prohibió los vuelos supersónicos comerciales sobre tierra debido a la preocupación por el ruido generado por los estampidos sónicos. Sin embargo hoy en día la tecnología de Quesst podría reducir drásticamente este ruido. El objetivo de la misión es recopilar datos del X-59 que podrían ayudar a los reguladores a ajustar la prohibición, considerando los niveles de ruido en lugar de la velocidad. “La idea de levantar la prohibición de los vuelos supersónicos sobre tierra firme es realmente emocionante”, comenta Bahm. “Y ése es el futuro que podría habilitar el X-59”. Mire este lapso de tiempo del ensamblaje del X-59 tal como ocurrió entre mayo de 2019 y junio de 2021 dentro de la fábrica Skunk Works de Lockheed Martin en Palmdale, California. El lanzamiento también representa algo más cercano al suelo–el logro del equipo trabajador y dedicado que llevó el avión de la imaginación a la realidad. Para ellos, el lanzamiento celebra las semanas, meses y años dedicados al desarrollo y construcción del X-59. “Para el equipo, algunos de los cuales han trabajado en el avión desde que se creó el primer componente, la presentación del X-59 será un momento muy especial.”comentó Bahm. “El diseño innovador del X-59 aprovecha décadas de trabajo para la NASA. Compartimos este logro con todos los que lo han hecho posible”. Una vez completado el ensamblaje, la misión de la NASA de silenciar el estampido sónico alcanzará un nuevo capítulo. Aunque todavía queda camino por recorrer, el futuro potencial de los viajes supersónicos comerciales está más cerca que antes. El equipo de la misión Quesst continuará ahora las pruebas en tierra firme antes del primer vuelo a finales de este año. “El lanzamiento es un gran logro, pero también significa que el siguiente logro es el primer vuelo, y después los vuelos supersónicos”, comentó Bahm. “Nuestros ojos están puestos en la misión”. El 30 de septiembre de 1968 tuvo lugar una ceremonia de lanzamiento memorable en la historia de la aviación, cuando el primer Boeing 747 hizo su debut público en la planta de ensamblaje de la compañía en Everett, cerca de Seattle. Para conmemorar el evento, asistieron a la ceremonia azafatas en representación de cada una de las 26 aerolíneas que habían comprado un avión 747.Boeing Artículo Traducido por: Elena Aguirre y Monica Uribe About the AuthorJohn GouldAeronautics Research Misson Directorate Read More Share Details Last Updated Jan 09, 2024 EditorLillian GipsonContactKristen Hatfieldkristen.m.hatfield@nasa.govMatt Kamletmatthew.r.kamlet@nasa.govSasha Ellissasha.c.ellis@nasa.govJim Bankejim.banke@nasa.gov Related TermsNASA en españolAeronáutica Explore More 2 min read Las leyendas de los pilotos de pruebas de la NASA se reúnen Article 4 days ago 3 min read La NASA anticipa el primer vuelo del avión experimental X-59 para 2024 Article 6 days ago 4 min read La movilidad aérea avanzada hace que los viajes sean más accesibles Article 3 weeks ago Keep Exploring Discover More Topics From NASA Aeronautics STEM Science Missions NASA History Aircraft Flown at Armstrong View the full article

Arcand For the first time, astronomers have combined data from NASA’s Chandra X-ray Observatory and James Webb Space Telescope to study the well-known supernova remnant Cassiopeia A (Cas A). This work has helped explain an unusual structure in the debris from the destroyed star called the “Green Monster,” because of its resemblance to the wall in the left field of Fenway Park. By combining the Webb data with X-rays from Chandra, researchers have concluded that the Green Monster was created by a blast wave from the exploded star slamming into material surrounding it. Detailed analysis found that filaments in the outer part of Cas A, from the blast wave, closely matched the X-ray properties of the Green Monster, including less iron and silicon than in the supernova debris. This interpretation is apparent from the color Chandra image, which shows that the colors inside the Green Monster’s outline best match with the colors of the blast wave rather than the debris with iron and silicon.

  14. Artemis II crew members (from left) CSA (Canadian Space Agency) astronaut Jeremy Hansen, and NASA astronauts Christina Koch, Victor Glover, and Reid Wiseman walk out of Astronaut Crew Quarters inside the Neil Armstrong Operations and Checkout Building to the Artemis crew transportation vehicles prior to traveling to Launch Pad 39B as part of an integrated ground systems test at Kennedy Space Center in Florida on Wednesday, Sept. 20, to test the crew timeline for launch day.NASA NASA announced Tuesday updates to its Artemis campaign that will establish the foundation for long-term scientific exploration at the Moon, land the first woman and first person of color on the lunar surface, and prepare for human expeditions to Mars for the benefit of all. To safely carry out these missions, agency leaders are adjusting the schedules for Artemis II and Artemis III to allow teams to work through challenges associated with first-time developments, operations, and integration. NASA will now target September 2025 for Artemis II, the first crewed Artemis mission around the Moon, and September 2026 for Artemis III, which is planned to land the first astronauts near the lunar South Pole. Artemis IV, the first mission to the Gateway lunar space station, remains on track for 2028. “We are returning to the Moon in a way we never have before, and the safety of our astronauts is NASA’s top priority as we prepare for future Artemis missions,” said NASA Administrator Bill Nelson. “We’ve learned a lot since Artemis I, and the success of these early missions rely on our commercial and international partnerships to further our reach and understanding of humanity’s place in our solar system. Artemis represents what we can accomplish as a nation – and as a global coalition. When we set our sights on what is hard, together, we can achieve what is great.” Ensuring crew safety is the primary driver for the Artemis II schedule changes. As the first Artemis flight test with crew aboard the Orion spacecraft, the mission will test critical environmental control and life support systems required to support astronauts. NASA’s testing to qualify components to keep the crew safe and ensure mission success has uncovered issues that require additional time to resolve. Teams are troubleshooting a battery issue and addressing challenges with a circuitry component responsible for air ventilation and temperature control. NASA’s investigation into unexpected loss of char layer pieces from the spacecraft’s heat shield during Artemis I is expected to conclude this spring. Teams have taken a methodical approach to understand the issue, including extensive sampling of the heat shield, testing, and review of data from sensors and imagery. The new timeline for Artemis III aligns with the updated schedule for Artemis II, ensures the agency can incorporate lessons learned from Artemis II into the next mission, and acknowledges development challenges experienced by NASA’s industry partners. As each crewed Artemis mission increases complexity and adds flight tests for new systems, the adjusted schedule will give the providers developing new capabilities – SpaceX for the human landing system and Axiom Space for the next-generation spacesuits – additional time for testing and any refinements ahead of the mission. “We are letting the hardware talk to us so that crew safety drives our decision-making. We will use the Artemis II flight test, and each flight that follows, to reduce risk for future Moon missions,” said Catherine Koerner, associate administrator, Exploration Systems Development Mission Directorate at NASA Headquarters in Washington. “We are resolving challenges associated with first-time capabilities and operations, and we are closer than ever to establishing sustained exploration of Earth’s nearest neighbor under Artemis.” In addition to the schedule updates for Artemis II and III, NASA is reviewing the schedule for launching the first integrated elements of Gateway, previously planned for October 2025, to provide additional development time and better align that launch with the Artemis IV mission in 2028. NASA also shared that it has asked both Artemis human landing system providers – SpaceX and Blue Origin – to begin applying knowledge gained in developing their systems as part of their existing contracts toward future variations to potentially deliver large cargo on later missions. “Artemis is a long-term exploration campaign to conduct science at the Moon with astronauts and prepare for future human missions to Mars. That means we must get it right as we develop and fly our foundational systems so that we can safely carry out these missions,” said Amit Kshatriya, deputy associate administrator of Exploration Systems Development, and manager of NASA’s Moon to Mars Program Office at headquarters. “Crew safety is and will remain our number one priority.” NASA leaders emphasized the importance of all partners delivering on time so the agency can maximize the flight objectives with available hardware on a given mission. NASA regularly assesses progress and timelines and as a part of integrated programmatic planning to ensure the agency and its partners can successfully accomplish its Moon to Mars exploration goals. With Artemis, NASA will explore more of the Moon than ever before, learn how to live and work away from home, and prepare for future human exploration of the Red Planet. NASA’s SLS (Space Launch System) rocket, exploration ground systems, and Orion spacecraft, along with the human landing system, next-generation spacesuits, Gateway lunar space station, and future rovers are NASA’s foundation for deep space exploration.

  15. 6 Min Read NASA’s Webb Finds Signs of Possible Aurorae on Isolated Brown Dwarf Artist's concept portrays the brown dwarf W1935. Credits: NASA, ESA, CSA, and L. Hustak (STScI) Infrared emission from methane suggests atmospheric heating by auroral processes. Astronomers using NASA’s James Webb Space Telescope have found a brown dwarf (an object more massive than Jupiter but smaller than a star) with infrared emission from methane, likely due to energy in its upper atmosphere. This is an unexpected discovery because the brown dwarf, W1935, is cold and lacks a host star; therefore, there is no obvious source for the upper atmosphere energy. The team speculates that the methane emission may be due to processes generating aurorae. These findings are being presented at the 243rd meeting of the American Astronomical Society in New Orleans. To help explain the mystery of the infrared emission from methane, the team turned to our solar system. Methane in emission is a common feature in gas giants like Jupiter and Saturn. The upper-atmosphere heating that powers this emission is linked to aurorae. Image: Artist Concept Brown Dwarf W1935 This artist concept portrays the brown dwarf W1935, which is located 47 light-years from Earth. Astronomers using NASA’s James Webb Space Telescope found infrared emission from methane coming from W1935. This is an unexpected discovery because the brown dwarf is cold and lacks a host star; therefore, there is no obvious source of energy to heat its upper atmosphere and make the methane glow. The team speculates that the methane emission may be due to processes generating aurorae, shown here in red.NASA, ESA, CSA, and L. Hustak (STScI) On Earth, aurorae are created when energetic particles blown into space from the Sun are captured by Earth’s magnetic field. They cascade down into our atmosphere along magnetic field lines near Earth’s poles, colliding with gas molecules and creating eerie, dancing curtains of light. Jupiter and Saturn have similar auroral processes that involve interacting with the solar wind, but they also get auroral contributions from nearby active moons like Io (for Jupiter) and Enceladus (for Saturn). For isolated brown dwarfs like W1935, the absence of a stellar wind to contribute to the auroral process and explain the extra energy in the upper atmosphere required for the methane emission is a mystery. The team surmises that either unaccounted internal processes like the atmospheric phenomena of Jupiter and Saturn, or external interactions with either interstellar plasma or a nearby active moon, may help account for the emission. A Detective Story The aurorae’s discovery played out like a detective story. A team led by Jackie Faherty, an astronomer at the American Museum of Natural History in New York, was awarded time with the Webb telescope to investigate 12 cold brown dwarfs. Among those were W1935 – an object that was discovered by citizen scientist Dan Caselden, who worked with the Backyard Worlds zooniverse project – and W2220, an object that was discovered using NASA’s Wide Field Infrared Survey Explorer. Webb revealed in exquisite detail that W1935 and W2220 appeared to be near clones of each other in composition. They also shared similar brightness, temperatures, and spectral features of water, ammonia, carbon monoxide, and carbon dioxide. The striking exception was that W1935 showed emission from methane, as opposed to the anticipated absorption feature that was observed toward W2220. This was seen at a distinct infrared wavelength to which Webb is uniquely sensitive. “We expected to see methane because methane is all over these brown dwarfs. But instead of absorbing light, we saw just the opposite: The methane was glowing. My first thought was, what the heck? Why is methane emission coming out of this object?” said Faherty. The team used computer models to infer what might be behind the emission. The modeling work showed that W2220 had an expected distribution of energy throughout the atmosphere, getting cooler with increasing altitude. W1935, on the other hand, had a surprising result. The best model favored a temperature inversion, where the atmosphere got warmer with increasing altitude. “This temperature inversion is really puzzling,” said Ben Burningham, a co-author from the University of Hertfordshire in England and lead modeler on the work. “We have seen this kind of phenomenon in planets with a nearby star that can heat the stratosphere, but seeing it in an object with no obvious external heat source is wild.” Image: Spectra W1935 vs W2220 Astronomers used NASA’s James Webb Space Telescope to study 12 cold brown dwarfs. Two of them – W1935 and W2220 – appeared to be near twins of each other in composition, brightness, and temperature. However, W1935 showed emission from methane, as opposed to the anticipated absorption feature that was observed toward W2220. The team speculates that the methane emission may be due to processes generating aurorae.NASA, ESA, CSA, and L. Hustak (STScI) Clues from our Solar System For clues, the team looked in our own backyard, to the planets of our solar system. The gas giant planets can serve as proxies for what is seen going on more than 40 light-years away in the atmosphere of W1935. The team realized that temperature inversions are prominent in planets like Jupiter and Saturn. There is still ongoing work to understand the causes of their stratospheric heating, but leading theories for the solar system involve external heating by aurorae and internal energy transport from deeper in the atmosphere (with the former a leading explanation). Brown Dwarf Aurora Candidates in Context This is not the first time an aurora has been used to explain a brown dwarf observation. Astronomers have detected radio emission coming from several warmer brown dwarfs and invoked aurorae as the most likely explanation. Searches were conducted with ground-based telescopes like the Keck Observatory for infrared signatures from these radio-emitting brown dwarfs to further characterize the phenomenon, but were inconclusive. W1935 is the first auroral candidate outside the solar system with the signature of methane emission. It’s also the coldest auroral candidate outside our solar system, with an effective temperature of about 400 degrees Fahrenheit (200 degrees Celsius), about 600 degrees Fahrenheit warmer than Jupiter. In our solar system the solar wind is a primary contributor to auroral processes, with active moons like Io and Enceladus playing a role for planets like Jupiter and Saturn, respectively. W1935 lacks a companion star entirely, so a stellar wind cannot contribute to the phenomenon. It is yet to be seen whether an active moon might play a role in the methane emission on W1935. “With W1935, we now have a spectacular extension of a solar system phenomenon without any stellar irradiation to help in the explanation.” Faherty noted. “With Webb, we can really ‘open the hood’ on the chemistry and unpack how similar or different the auroral process may be beyond our solar system,” she added. 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. Want to help discover a new world? Want to help discover a new world?

  16. 2 min read Be a Burst Chaser and Witness the Most Powerful Explosions in the Universe! The Burst Chaser Project was launched today at the American Astronomical Society meeting in New Orleans, Louisiana. Credit: NASA Goddard Space Flight Center/Zooniverse Yes, the universe IS talking to you! Gamma-ray bursts, massive explosions visible from everywhere in the observable universe, are telling us something about how stars end their lives and how massive black holes form. Now astronomers are asking you join the Burst Chaser project to read the signals from these bursts and decode what the universe is saying. NASA’s Neil Gehrels SWIFT observatory regularly detects pulses of gamma rays, a very energetic form of light, coming from billions of light years away. At Burst Chaser, you’ll examine plots that show how much gamma ray energy arrived at this space telescope as a function of time and classify their shapes—the pulse shapes. Gamma-ray bursts are known to be mostly connected to supernovae or the mergers of neutron stars and black holes, but exactly how these events produce pulses with such a variety of characteristics remains a mystery. “We need your help to classify these pulses for more clues of what they really are!” said Professor Amy Lien from the University of Tampa, the project’s Principal Investigator. Besides professional astronomers like Lien, the project’s science team includes three undergraduate students from the University of Tampa: Katherine Kurilov, Carter Murawski, and Sebastian Reisch. Several NASA volunteers also helped design the project: Sovan Acharya, Eduardo Antonini, Sumit Banerjee, Marco Zaccaria Di Fraia, Jonathan Holden, Vikrant Kurmude, Hugo Durantini Luca, Orleo Marinaro, John Yablonsky, and U.S. military veteran, Danny Roylance, interviewed here. The project platform is hosted by Zooniverse, a NASA Partner. You can join this amazing collaboration, too.

  17. ESA/Hubble & NASA, J. Dalcanton, Dark Energy Survey/DOE/FNAL/NOIRLab/NSF/AURA; Acknowledgment: L. Shatz This image from the NASA/ESA Hubble Space Telescope features a richness of spiral galaxies: the large, prominent spiral galaxy on the right side of the image is NGC 1356; the two apparently smaller spiral galaxies flanking it are LEDA 467699 (above it) and LEDA 95415 (very close at its left) respectively; and finally, IC 1947 sits along the left side of the image. This image is a really interesting example of how challenging it can be to tell whether two galaxies are actually close together, or just seem to be from our perspective here on Earth. A quick glance at this image would likely lead you to think that NGC 1356, LEDA 467699, and LEDA 95415 were all close companions, while IC 1947 was more remote. However, we have to remember that two-dimensional images such as this one only give an indication of angular separation: that is, how objects are spread across the sphere of the night sky. What they cannot represent is the distance objects are from Earth. For instance, while NGC 1356 and LEDA 95415 appear to be so close that they must surely be interacting, the former is about 550 million light-years from Earth and the latter is roughly 840 million light-years away, so there is nearly a whopping 300 million light-year separation between them. That also means that LEDA 95415 is likely nowhere near as much smaller than NGC 1356 as it appears to be. On the other hand, while NGC 1356 and IC 1947 seem to be separated by a relative gulf in this image, IC 1947 is only about 500 million light-years from Earth. The angular distance apparent between them in this image only works out to less than 400,000 light-years, so they are actually much closer neighbors in three-dimensional space than NGC 1356 and LEDA 95415!

  19. 4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Experimental Fabrication Shop technicians created parts for the assembly of a Transonic Truss-Braced Wing model. Based at NASA’s Armstrong Flight Research Center in Edwards, California, the technicians also assembled sections, and did a final fit-check to ensure the wing model was ready for testing. Credits: NASA/Quincy Eggert German Escobar works on a model aircraft wing structure that has two long sides and bars in between, which resembles a mini ladder. He sands the rough edges, uses four vices to secure it, and uses a milling machine he programmed to make precision holes. Escobar is one of the Experimental Fabrication Shop technicians at NASA’s Armstrong Flight Research Center, Edwards California. The team made 29 different types of parts, more than 50 in total, to assemble a 10-foot unique wing model that will help calibrate fiber optic instrumentation and contribute data for a future wing model to show how the design improves fuel efficiency. The experimental wing model has many features of the X-66 Transonic Truss-Braced Wing. The X-66 wing is braced on an aircraft using diagonal struts that also add lift and could result in significantly improved aerodynamics. German Escobar works on milling the strut frame assembly for a 10-foot model of the Transonic Truss-Braced Wing at NASA’s Armstrong Flight Research Center in Edwards, California. The aircraft concept involves a wing braced on an aircraft using diagonal struts that also add lift and could result in significantly improved aerodynamics.NASA/Steve Freeman NASA Armstrong’s many capabilities enabled a start-to-finish design, fabrication, and soon testing of the 10-foot model wing. The Flight Loads Laboratory provided specifications for the model, including some of its own calculations from a 6-foot efficient wing test build at the center in Dec. 21, 2022. NASA’s Advanced Air Transportation Technology project funded the model wings. In addition, NASA Armstrong and NASA’s Langley Research Center in Hampton, Virginia, are working on a proposal for 15-foot wing called the Structural Wing Experiment Evaluating Truss-Bracing. That wing would include ground vibration testing that would give a clearer picture of how it would react to different kinds of vibration in flight. Andrew Holguin, a design engineer, created 3D representations of the parts and how to assemble them. Holguin divided the model wing work into subassemblies to make it easier to focus on a single set of tasks. With the design fully approved and the task orders written, Escobar began his work. Jose Vasquez programed a machine to cut, rotate and turn a block of steel to form a jury strut adaptor for a 10-foot model of the Transonic Truss-Braced Wing at NASA’s Armstrong Flight Research Center, in Edwards, California. The aircraft concept involves a wing braced on an aircraft using diagonal struts that also add lift and could result in significantly improved aerodynamics.NASA/Steve Freeman The ability to work items simultaneously is an advantage. Jose Vasquez, an engineering technician, used software to instruct a five-axis milling machine how to cut, rotate and transform a block of steel into an adapter. Water shoots at the cutting mechanism to keep everything from getting too hot. Once the part was finished, Vasquez removed it from the machine cleaned it and used a pair of calipers, and a fine measurement tool called a micrometer, to check ensure the adaptor meets the wing model’s precise needs. If a calibration tool does not exist to check a specialized component, technicians can make one. Elsewhere in the lab, sheet metal technician Matt Sanchez used a press brake to make bends in an aluminum sheet to form a rectangle called a wing rib. In another step he added hardware to the rib and later installed it in the model wing. Matthew Sanchez attaches the strut and the wing to ensure they fit together as intended for a 10-foot model of the Transonic Truss-Braced Wing at NASA’s Armstrong Flight Research Center in Edwards, California. The aircraft concept involves a wing braced on an aircraft using diagonal struts that also add lift and could result in significantly improved aerodynamics.NASA/Genaro Vavuris As the assembly was nearly complete, an outer wing cover was required. Sanchez set up the drawings, placed a sheet of aluminum into the water jet table and started it. Under the water the saw moved quickly to cut the strut covering down, around, and up the other side, and stopping with the complete cut. Sanchez took the piece from the table and dried it. To wrap up this part of the work, he did a successful check of all the components called a fit check. With the wing model complete, the Flight Loads Laboratory staff continues to complete design and preparations to build a fixture for the wing tests. The fixture will join the experimental wing model, test instrumentation, and enable tests that can contribute to the next aviation innovation. Here is a gallery of the building of the parts and the wing.

Arcand For the first time astronomers have combined data from NASA’s Chandra X-ray Observatory and James Webb Space Telescope to study the well-known supernova remnant Cassiopeia A (Cas A). As described in our latest press release, this work has helped explain an unusual structure in the debris from the destroyed star called the “Green Monster”, first discovered in Webb data in April 2023. The research has also uncovered new details about the explosion that created Cas A about 340 years ago, from Earth’s perspective. A new composite image contains X-rays from Chandra (blue), infrared data from Webb (red, green, blue), and optical data from Hubble (red and white). The outer parts of the image also include infrared data from NASA’s Spitzer Space Telescope (red, green and blue). The outline of the Green Monster can be seen by mousing over the image. The Chandra data reveals hot gas, mostly from supernova debris from the destroyed star, including elements like silicon and iron. In the outer parts of Cas A the expanding blast wave is striking surrounding gas that was ejected by the star before the explosion. The X-rays are produced by energetic electrons spiraling around magnetic field lines in the blast wave. These electrons light up as thin arcs in the outer regions of Cas A, and in parts of the interior. Webb highlights infrared emission from dust that is warmed up because it is embedded in the hot gas seen by Chandra, and from much cooler supernova debris. The Hubble data shows stars in the field. A separate graphic shows a color Chandra image, where red shows iron and magnesium at low X-ray energies, green shows silicon at intermediate X-ray energies and blue shows the highest energy X-rays, from electrons spiraling around magnetic field lines. An outline of the Green Monster, plus the locations of the blast wave, and of debris rich in silicon and iron are labeled. Chandra Image of Cassiopeia A, LabeledCredit: NASA/CXC/SAO Detailed analysis by the researchers found that filaments in the outer part of Cas A, from the blast wave, closely matched the X-ray properties of the Green Monster, including less iron and silicon than in the supernova debris. This interpretation is apparent from the color Chandra image, which shows that the colors inside the Green Monster’s outline best match with the colors of the blast wave rather than the debris with iron and silicon. The authors conclude that the Green Monster was created by a blast wave from the exploded star slamming into material surrounding it, supporting earlier suggestions from the Webb data alone. The debris from the explosion is seen by Chandra because it is heated to tens of millions of degrees by shock waves, akin to sonic booms from a supersonic plane. Webb can see some material that has not been affected by shock waves, what can be called “pristine” debris. To learn more about the supernova explosion, the team compared the Webb view of the pristine debris with X-ray maps of radioactive elements that were created in the supernova. They used NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) data to map radioactive titanium — still visible today — and Chandra to map where radioactive nickel was by measuring the locations of iron. Radioactive nickel decays to form iron. An additional image shows the iron-rich debris (tracing where radioactive nickel was located) in green, the radioactive titanium in blue and the pristine debris seen in orange and yellow. Iron/Titanium/Pristine Debris Cassiopeia A, LabeledCredit: NASA/CXC/SAO Some filaments of pristine debris near the center of Cas A, seen with Webb, are connected to the iron seen with Chandra farther out. Radioactive titanium is seen where pristine debris is relatively weak. These comparisons suggest that radioactive material seen in X-rays has helped shape the pristine debris near the center of the remnant seen with Webb, forming cavities. The fine structures in the pristine debris were most likely formed when the star’s inner layers were violently mixed with hot, radioactive matter produced during collapse of the star’s core under gravity. These results were presented by Dan Milisavljevic from Purdue University at the 243rd meeting of the American Astronomical Society in New Orleans. They are described in more detail in two papers submitted to Astrophysical Journal Letters, one led by Milisavljevic focused on the Webb results (preprint here) and the other led by Jacco Vink of the University of Amsterdam focused on the Chandra results (preprint here). The co-authors of Vink’s paper are Manan Agarwal (University of Amsterdam, the Netherlands), Patrick Slane (Center for Astrophysics | Harvard & Smithsonian – CfA), Ilse De Looze (Ghent University, Belgium), Dan Milisavljevic, Daniel Patnaude (CfA), Paul Plucinsky (CfA), and Tea Temin (Princeton University).

  21. As part of NASA’s Commercial Lunar Payload Services initiative, Astrobotic’s Peregrine lander launched on United Launch Alliance’s (ULA) Vulcan rocket at 2:18 a.m. EST from Launch Complex 41 at Cape Canaveral Space Force Station in Florida. Carrying NASA scientific instruments as part of its Commercial Lunar Payload Services initiative, Astrobotic’s Peregrine lander launched on United Launch Alliance’s (ULA) Vulcan rocket at 2:18 a.m. EST from Launch Complex 41 at Cape Canaveral Space Force Station in Florida. Peregrine has about a 46-day journey to reach the lunar surface. Once on the Moon, NASA instruments will study the lunar exosphere, thermal properties of the lunar regolith, hydrogen abundances in the soil at the landing site, and conduct radiation environment monitoring. The five NASA science and research payloads aboard the lander will help the agency better understand planetary processes and evolution, search for evidence of water and other resources, and support long-term, sustainable human exploration. “The first CLPS launch has sent payloads on their way to the Moon – a giant leap for humanity as we prepare to return to the lunar surface for the first time in over half a century,” said NASA Administrator Bill Nelson. “These high-risk missions will not only conduct new science at the Moon, but they are supporting a growing commercial space economy while showing the strength of American technology and innovation. We have so much science to learn through CLPS missions that will help us better understand the evolution of our solar system and shape the future of human exploration for the Artemis Generation.” For this CLPS flight, NASA research includes: Laser Retroreflector Array: A collection of approximately half-inch (1.25 cm.) retro-reflectors – a mirror used for measuring distance – mounted to the lander. This mirror reflects laser light from other orbiting and landing spacecrafts to precisely determine the lander’s position. Neutron Spectrometer System: This system will search for indicators of water near the lunar surface by detecting the presence of hydrogen-bearing materials at the landing site as well as determining bulk properties of the regolith there. Linear Energy Transfer Spectrometer: This radiation sensor will collect information about the lunar radiation environment and any solar events that might occur during the mission. The instrument relies on flight-proven hardware that flew in space on the Orion spacecraft’s inaugural uncrewed flight in 2014. Near InfraRed Volatiles Spectrometer System: This system will measure surface hydration and volatiles. It will also detect certain minerals using spectroscopy while mapping surface temperature and changes at the landing site. Peregrine Ion-Trap Mass Spectrometer: This instrument will study the thin layer of gases on the Moon’s surface, called the lunar exosphere, and any gases present after descent and landing and throughout the lunar day to understand the release and movement of volatiles. It was previously developed for ESA’s (European Space Agency) Rosetta mission. Peregrine is scheduled to land on the Moon on Friday, Feb. 23, and will spend approximately 10 days gathering valuable scientific data studying Earth’s nearest neighbor and helping pave the way for the first woman and first person of color to explore the Moon under Artemis.

  22. NASA and the Mohammed Bin Rashid Space Centre (MBRSC) have entered into an agreement for MBRSC to provide the Crew and Science Airlock module for the Gateway Space Station. As part of the agreement, NASA will fly a United Arab Emirates astronaut to Gateway on a future Artemis mission. Pictured is an artist’s concept of Gateway (left) and an artist’s concept of a government reference airlock (right).NASA NASA and the Mohammed bin Rashid Space Centre (MBRSC) of the United Arab Emirates (UAE) announced Sunday plans for the space centre to provide an airlock for Gateway, humanity’s first space station that will orbit the Moon. The lunar space station will support NASA’s missions for long-term exploration of the Moon under Artemis for the benefit of all. “As chair of the National Space Council, I have made it a priority to enhance international cooperation in space. Today’s announcement and partnership between the United States and United Arab Emirates advances this important work. By combining our resources, scientific capacity, and technical skill, the U.S. and UAE will further our collective vision for space and ensure it presents extraordinary opportunities for everyone here on Earth,” said Vice President Kamala Harris. Under a new implementing arrangement expanding their human spaceflight collaboration with NASA through Gateway, MBRSC will provide Gateway’s Crew and Science Airlock module, as well as a UAE astronaut to fly to the lunar space station on a future Artemis mission. “The United States and the United Arab Emirates are marking a historic moment in our nations’ collaboration in space, and the future of human space exploration,” said NASA Administrator Bill Nelson. “We are in a new era of exploration through Artemis – strengthened by the peaceful and international exploration of space. The UAE’s provision of the airlock to Gateway will allow astronauts to conduct groundbreaking science in deep space and prepare to one day send humanity to Mars.” In addition to operating the airlock, MBRSC also will provide engineering support for the life of the lunar space station. The airlock will allow crew and science research transfers to and from the habitable environment of Gateway’s pressurized crew modules to the vacuum of space. These transfers will support broader science in the deep space environment, as well as Gateway maintenance. Gateway will support sustained exploration and research in deep space, provide a home for astronauts to live and work, including a staging point for lunar surface missions, and an opportunity to conduct spacewalks while orbiting the Moon. NASA’s Artemis program is the most diverse and broad coalition of nations in human exploration in deep space. In collaboration with the CSA (Canadian Space Agency), ESA (European Space Agency), JAXA (Japan Aerospace Exploration Agency), and now the MBRSC, NASA will return humans to the lunar surface for scientific discovery and chart a path for the first human missions to Mars. This latest cooperation on Gateway builds on NASA’s and UAE’s previous human spaceflight collaboration. In 2019, Hazzaa Almansoori became the first Emirati to fly to space during a short mission to the International Space Station, in which he collaborated with NASA to perform experiments and educational outreach. A second Emirati astronaut, Sultan Al Neyadi, launched to the space station in 2023 on NASA’s SpaceX Crew-6 mission, where he participated in the floating laboratory’s scientific research that advances human knowledge and improves life on Earth. The UAE currently has two additional astronaut candidates in training at NASA’s Johnson Space Center in Houston. NASA has also worked with UAE on Mars research and human research and analog studies to support mutual exploration priorities. In 2020, the United States and UAE were among the original signers of the Artemis Accords, which are a practical set of principles to guide space exploration cooperation among nations participating in NASA’s 21st century lunar exploration program. Through Artemis, NASA will land the first woman and the first person of color on the surface of the Moon, paving the way for a long-term lunar presence and serving as a steppingstone to send the first astronauts to Mars. https://www.nasa.gov/artemis -end- Vanessa Lloyd / Kathryn Hambleton Headquarters, Washington 202-358-1600 vanessa.c.lloyd@nasa.gov / kathryn.hambleton@nasa.gov Dylan Connell Johnson Space Center, Houston 281-483-5111 dylan.b.connell@nasa.gov Share Details Last Updated Jan 07, 2024 LocationNASA Headquarters Related TermsArtemisGateway ProgramGateway Space StationMissions View the full article

The image is a mosaic taken by the WAC (Wide Angle Camera) one of three cameras on the LROC (Lunar Reconnaissance Orbiter Camera), which was launched into lunar orbit in 2009. Credit: NASA/GSFC/ Arizona State University NASA will kick off 2024 by sending five payloads to the Moon aboard Astrobotic’s Peregrine lander, Astrobotic Peregrine Mission One. The inaugural launch under the agency’s CLPS (Commercial Lunar Payload Services) initiative will blast off Monday, Jan. 8, from Cape Canaveral, Florida, on a United Launch Alliance Vulcan rocket. The suite of NASA payloads aboard Peregrine One will aim to locate water molecules on the Moon, measure radiation and gases around the lander, and evaluate the lunar exosphere (the thin layer of gases on the Moon’s surface). These measurements will improve our understanding of how solar radiation interacts with the lunar surface. The payloads will also provide data to NASA’s Lunar-VISE (Lunar Vulkan Imaging and Spectroscopy Explorer) instrument suite, slated to land on the Gruithuisen Domes in 2026. “We are so excited to see this vision become a reality. CLPS is an innovative way of leveraging American companies to send important science and technology payloads to the Moon,” said Nicola Fox, associate administrator, Science Mission Directorate at NASA Headquarters in Washington. “The Moon is a rich destination for scientific discovery. Studying and sampling the lunar environment will help NASA unravel some of the greatest mysteries of our solar system for the benefit of all.” The Peregrine lander is targeted to land Feb. 23 at Sinus Viscositatis, a lunar feature outside of the hardened lava Gruithuisen Domes on the near side of the Moon. Similar natural structures on Earth require large volumes of water to form, leading scientists to believe that this landing site may contain evidence of water on the Moon. The five NASA payloads aboard Astrobotic’s Peregrine One lander include the following: The LETS (Linear Energy Transfer Spectrometer) payload is a radiation monitor derived from heritage hardware flown on Orion Exploration Flight Test-1 in 2014. LETS will collect data on the lunar radiation environment and demonstrate the capabilities of the radiation monitors themselves on the lunar surface. LETS units also were flown as BioSentinel payloads aboard Artemis I and aboard the International Space Station. LETS uses the same core technology as the Hybrid Electronic Radiation Assessor system, the primary radiation monitor on Artemis missions. Payload principal investigator: Dr. Edward Semones, NASA’s Johnson Space Center. NIRVSS (Near-Infrared Volatile Spectrometer System) will reveal the composition and surface temperature and fine-scale structure of the lunar soil at the landing site. NIRVSS features an imager, spectrometer, and thermal sensor to study the lunar soil and detect which types of minerals and volatiles are present. Payload principal investigator: Dr. Anthony Colaprete, NASA’s Ames Research Center The NSS (Neutron Spectrometer System) is an instrument capable of indirectly detecting potential water present in the lunar soil at the landing site, as a result of the water in the exhaust deposited by the lander’s engines. After landing, the system will measure any changes in the characteristics of the lunar soil over the course of a lunar day. Payload principal investigator: Dr. Richard Elphic, NASA Ames PITMS (Peregrine Ion-Trap Mass Spectrometer) will investigate the makeup of compounds in the thin lunar atmosphere after descent and landing, and throughout the lunar day, to understand the release and movement of volatiles such as water, gases, and other chemical compounds. PITMS is a partnership between NASA, The Open University in Milton Keynes, England, and ESA (European Space Agency). Payload principal investigator: Dr. Barbara Cohen, NASA’s Goddard Space Flight Center LRA (Laser Retroreflector Array) is a collection of eight retroreflectors that enable precise measurements of the distance between the orbiting or landing spacecraft and the lander. LRA is a passive optical instrument and will function as a permanent location marker on the Moon for decades to come. Payload principal investigator: Dr. Xiaoli Sun, NASA Goddard Astrobotic is one of 14 vendors eligible to carry NASA payloads to the Moon through the CLPS initiative, which began in 2018 and is designed to establish a commercial marketplace for science, exploration, and technology development investigations on the Moon’s surface and in lunar orbit. Through CLPS, NASA aims to gain new insights into the lunar environment and expand the lunar economy to support future crewed missions under the Artemis program.
