NASA Welcomes Chile as Newest Artemis Accords Signatory

Chile signed the Artemis Accords Friday during a ceremony hosted by NASA Administrator Bill Nelson at the agency’s headquarters in Washington, becoming the 47th nation and the seventh South American country to commit to the responsible exploration of space for all humanity.

“Today we welcome Chile’s signing of the Artemis Accords and its commitment to the shared values of all the signatories for the exploration of space,” said Nelson. “The United States has long studied the stars from Chile’s great Atacama Desert. Now we will go to the stars together, safely, and responsibly, and create new opportunities for international cooperation and the Artemis Generation.”

Aisén Etcheverry, minister of science, technology, knowledge and innovation, signed the Artemis Accords on behalf of Chile. Jennifer Littlejohn, acting assistant secretary, Bureau of Oceans and International Environmental and Scientific Affairs, U.S. Department of State, and Juan Gabriel Valdés, ambassador of Chile to the United States, also participated in the event.

“The signing marks a significant milestone for Chile, particularly as our government is committed to advancing technological development as a key pillar of our national strategy,” said Etcheverry. “Chile has the opportunity to engage in the design and development of world-leading scientific and technological projects. Moreover, this collaboration allows us to contribute to areas of scientific excellence where Chile has distinguished expertise, such as astrobiology, geology, and mineralogy, all of which are critical for the exploration and colonization of space.”

Earlier in the day, Nelson also hosted the Dominican Republic at NASA Headquarters to recognize the country’s signing of the Artemis Accords Oct. 4. Sonia Guzmán, ambassador of the Dominican Republic to the United States, delivered the signed Artemis Accords to the NASA administrator. Mike Overby, acting deputy assistant secretary, Bureau of Oceans and International Environmental and Scientific Affairs, U.S. Department of State, and other NASA officials attended the event.

In 2020, the United States, led by NASA and the U.S. Department of State, and seven other initial signatory nations established the Artemis Accords, identifying an early set of principles promoting the beneficial use of space for humanity. The Artemis Accords are grounded in the Outer Space Treaty and other agreements including the Registration Convention, the Rescue and Return Agreement, as well as best practices and norms of responsible behavior that NASA and its partners have supported, including the public release of scientific data. 

The commitments of the Artemis Accords and efforts by the signatories to advance implementation of these principles support the safe and sustainable exploration of space. More countries are expected to sign in the coming weeks and months.

Red Rocks with Green Spots at ‘Serpentine Rapids’

After discovering and sampling the “leopard spots” of “Bright Angel,” it became apparent that Perseverance’s journey of discovery in this region was not yet finished. Approximately 20 sols (Martian days) after driving south across Neretva Vallis from Bright Angel, the rover discovered the enigmatic and unique red rocks of “Serpentine Rapids.”

At Serpentine Rapids, Perseverance used its abrading bit to create an abrasion patch in a red rock outcrop named “Wallace Butte.” The 5-cm diameter abrasion patch revealed a striking array of white, black, and green colors within the rock. One of the biggest surprises for the rover team was the presence of the drab-green-colored spots within the abrasion patch, which are composed of dark-toned cores with fuzzy, light green rims.

On Earth, red rocks — sometimes called “red beds” — generally get their color from oxidized iron (Fe3+), which is the same form of iron that makes our blood red, or the rusty red color of metal left outside. Green spots like those observed in the Wallace Butte abrasion are common in ancient “red beds” on Earth and form when liquid water percolates through the sediment before it hardens to rock, kicking off a chemical reaction that transforms oxidized iron to its reduced (Fe2+) form, resulting in a greenish hue. On Earth, microbes are sometimes involved in this iron reduction reaction. However, green spots can also result from decaying organic matter that creates localized reducing conditions. Interactions between sulfur and iron can also create iron-reducing conditions without the involvement of microbial life.

Unfortunately, there was not enough room to safely place the rover arm containing the SHERLOC and PIXL instruments directly atop one of the green spots within the abrasion patch, so their composition remains a mystery. However, the team is always on the lookout for similar interesting and unexpected features in the rocks.

The science and engineering teams are now dealing with incredibly steep terrain as Perseverance ascends the Jezero Crater rim. In the meantime, the Science Team is hanging on to the edge of their seats with excitement and wonder as Perseverance makes the steep climb out of the crater it has called home for the past two years. There is no shortage of wonder and excitement across the team as we contemplate what secrets the ancient rocks of the Jezero Crater rim may hold.

Destacado de la NASA: Felipe Valdez, un ingeniero inspirador

Read this story in English here.

Felipe Valdez es una persona que aprovechó todas las oportunidades posibles en la NASA, trabajando desde que inicio como pasante universitario hasta su trabajo actual como ingeniero de controles de vuelo. 

Nacido en los Estados Unidos pero criado en México, Valdez enfrentó grandes desafíos mientras crecía.    

“Mi madre trabajaba por largas horas, mi padre batallaba contra la adicción, y eventualmente la escuela se volvió inaccesible,” dijo Valdez. 

Determinado a continuar su educación, Valdez tomó la difícil decisión de dejar a su familia y regresar a EE. UU. Pero en su adolescencia, aprender inglés y adaptarse a un nuevo ambiente fue un choque cultural para él. A pesar de estos cambios, su curiosidad por materias como las matemáticas y la ciencia nunca decayó.

“De niño, siempre se me ha facilitado trabajar con los números y me fascinaba cómo funcionaban las cosas. La ingeniería combinó ambas cosas,” dijo Valdez. “Eso despertó mi interés.”

Mientras estudiaba ingeniería mecánica en la Universidad Estatal de California en Sacramento, la orientación de su profesor, José Granda, resultó fundamental.  

“Él me animó a solicitar una pasantía en la NASA,” dijo Valdez. “Él había sido portavoz en español para una misión de transbordador [espacial], así que al escuchar que alguien con mis antecedentes tuvo éxito me dio la confianza que yo necesitaba para dar ese paso”. 

El esfuerzo de Valdez valió la pena – él fue seleccionado como pasante en la Oficina de STEM de la NASA en el Centro Espacial Johnson en Houston. Allí, él trabajó en el desarrollo de software para la dinámica de vehículos, actuadores y modelos de controladores para una cápsula espacial en simulaciones por computadora.

“No podía creerlo,” dijo Valdez. “Conseguir esa oportunidad cambió todo.”

Esta pasantía abrió la puerta a una segunda oportunidad con la NASA, esta vez en el Centro de Investigación de Vuelo Armstrong de la agencia en California. Tuvo la oportunidad de trabajar en el desarrollo de computadoras de vuelo para el Diseño Aerodinámico de Investigación Preliminar para Disminuir la Resistencia, un diseño experimental de ala volante.  

Después de estas experiencias, fue aceptado como un pasante en el Programa Pathways de la NASA, un programa de trabajo y estudio que ofrece la posibilidad de trabajar a tiempo completo en la NASA después de graduarse. 

“Eso fue el comienzo de mi carrera en la NASA, donde realmente despego mi pasión por la aeronáutica,” dijo Valdez. 

Valdez fue el primero en su familia en seguir una educación superior, obteniendo su licenciatura en la Universidad Estatal de Sacramento y su maestría en ingeniería mecánica y aeroespacial en la Universidad de California, Davis.

Hoy en día, trabaja como ingeniero de controles de vuelo de la NASA en la rama de Dinámica y Controles del centro Armstrong. La mayor parte de su experiencia se ha centrado en el desarrollo de simulaciones de vuelo y diseño de sistemas de control, particularmente para aviones de propulsión eléctrica distribuida. 

“Es gratificante formar parte de un grupo que se centra en hacer que la aviación sea más rápida, más silenciosa, y más sostenible,” dijo Valdez. “Como ingeniero de controles, trabajar en conceptos avanzados de aeronaves como la propulsión eléctrica distribuida me permite diseñar algoritmos para controlar directamente múltiples motores, mejorando la seguridad, la controlabilidad y la estabilidad, al tiempo que permite operaciones más limpias y silenciosas que amplían los límites de la aviación sostenible.”

A lo largo de su carrera, Valdez se ha sentido orgulloso de su herencia. “Siento un fuerte orgullo de saber que la inclusión es uno de nuestros valores fundamentales aquí en la NASA y que las oportunidades están abiertas para todos.”

NASA Stennis Achieves Milestone in Preparation for Future Artemis Testing

NASA’s Stennis Space Center near Bay St. Louis, Mississippi, achieved a key milestone this week for testing a new SLS (Space Launch System) rocket stage to fly on future Artemis missions to the Moon and beyond.

Over a two-week period beginning Oct. 10, crews completed a safe lift and installation of the interstage simulator component needed for future testing of NASA’s exploration upper stage (EUS) in the B-2 position of the Thad Cochran Test Stand. The component will function like the SLS interstage section that helps protect the upper stage during Artemis launches.

“NASA Stennis is at the front end of the critical path for future space exploration,” said Barry Robinson, project manager for exploration upper stage Green Run testing on the Thad Cochran Test Stand. “Installing the interstage simulator is a significant step in our preparation to ensure the new, more powerful upper stage is ready to safely fly on future Artemis missions.”

The EUS unit, built by Boeing at NASA’s Michoud Assembly Facility in New Orleans, which will be the upper stage for the evolved Block 1B version of SLS and will enable NASA to launch its most ambitious deep space missions. The new stage will replace the current interim cryogenic propulsion stage on the Block 1 version of SLS, which features a single engine and is capable of lifting 27 tons of crew and cargo to lunar orbit.

The new exploration upper stage will be powered by four RL10 engines, manufactured by SLS engines contractor L3Harris. It will increase payload capacity by 40%, enabling NASA to send 38 tons of cargo with a crew to the Moon or 42 tons of cargo without a crew.

Before the first flight of the exploration upper stage on the Artemis IV mission, the stage will undergo a series of Green Run tests of its integrated systems at NASA Stennis. The test series will culminate with a hot fire of the stage’s four RL10 engines, just as during an actual mission.

The simulator component installed on the Thad Cochran Test Stand (B-2) at NASA Stennis weighs 103 tons and measures 31 feet in diameter and 33 feet tall. It will function like the SLS interstage section to protect EUS electrical and propulsion systems during Green Run testing. The top portion of the simulator also will serve as a thrust takeout system to absorb the thrust of the EUS hot fire and transfer it back to the test stand. The four-engine EUS provides more than 97,000 pounds of thrust.

NASA Stennis crews previously lifted the interstage simulator to measure and align it relative to the test stand. It is now outfitted with all piping, tubing, and electrical systems necessary to support future Green Run testing.

Installation onto the test stand enables NASA Stennis crews to begin fabricating the mechanical and electrical systems connecting the facility to the simulator. As fabrication of the systems are completed, crews will conduct activation flows to ensure the test stand can operate to meet test requirements.

Through Artemis, NASA will establish the foundation for long-term scientific exploration at the Moon; land the first woman, first person of color and first international partner astronaut on the lunar surface; and prepare for human expeditions to Mars for the benefit of all.
