As RS-25’s operations integrator, Chris Pereira is responsible for ensuring that the many pieces of the program – from tracking on-time procurement of supplies and labor loads to coordinating priorities on various in-demand machine centers – come together to deliver a quality product. Chris Pereira can personally attest to the immense gravitational attraction of black holes. He’s been in love with space ever since he saw a video on the topic in a high school science class.
But it wasn’t just any science class. It was one specially designed for English learners.
“I was born and raised in Guatemala,” Pereira said. “I came here at 14 unable to speak any English.”
Pereira did not know how to navigate the U.S. educational system either, but after that class, he was certain he wanted a career in space.
Thus began a journey that ultimately landed him at L3Harris Technologies, where he works in the Aerojet Rocketdyne segment as an engineer and operations integrator on the RS-25 engine – used to power the core stage of NASA’s SLS (Space Launch System) rocket that will launch astronauts to the Moon under NASA’s Artemis campaign.
Pereira’s first step was to stay after class and ask to borrow a copy of the video on black holes. His teacher not only obliged but took him across the street to the local library to get his first library card.
Pereira quickly recognized that the pathway to his desired career in space was through higher education. It was equally clear, however, that he was not yet on that pathway. English as a Second Language classes, including that science class, did not count toward college admissions. His guidance counselor, meanwhile, was nudging him toward the trades.
But with the help of teachers and a new guidance counselor, he got himself on the college-bound track.
“I came to understand there were multiple career pathways to explore my interest in space,” Pereira said “One was engineering.”
There was a lot of catching up to do, so Pereira took eight classes per day, including honors courses. He also worked every day after school cleaning a gymnasium from 6 to 11 p.m. to help his family make ends meet.
Pereira earned his mechanical engineering degree at California State University at Los Angeles while also working as a senior educator at the California Science Center to cover the cost of his college tuition and living expenses.
Pereira’s first career experience was as an intern in manufacturing engineering at Aerojet Rocketdyne. “I learned that making 100% mission-success engines requires a strong culture of attention to detail, teamwork and solid work ethics.” Pereira said. His first full-fledged engineering job was with Honeywell Aerospace working on aircraft programs.
Eventually, space came calling — literally. “My mentor at Aerojet Rocketdyne called me up and said, ‘Chris, I have a job for you,’” Pereira said.
He began his new job working on rocket engine programs including the AR1 and RS-68 but shifted to the RS-25 after NASA awarded Aerojet Rocketdyne a contract for newly manufactured versions of the engine. Initial versions of the SLS are using refurbished engines from the Space Shuttle Program. Evolved versions of the RS-25 recently concluded a critical test series and will debut with the fifth Artemis flight.
As RS-25’s operations integrator, Pereira is responsible for ensuring that the many pieces of the program – from tracking on-time procurement of supplies and labor loads to coordinating priorities on various in-demand machine centers – come together to deliver a quality product.
Playing a key role in the nation’s effort to return astronauts to the Moon feels a bit like coming home again, Pereira said. “You develop your first love, work really hard, take different pathways and encounter new passions,” he said. “It’s almost funny how the world and life work out – it’s like I’ve taken a big circle back to my first love.”
NASA is working to land the first woman, first person of color, and its first international partner astronaut on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, supporting ground systems, advanced spacesuits and rovers, the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.

Students are recognized for their hard work in STEM-related extended-day programs at their school through a partnership with NASA’s Langley Research Center in Hampton, Virginia.Credit: NASA Media are invited to the kickoff event of a collaboration between NASA and the U.S. Department of Education at 4 p.m. EDT Monday, Sept. 23, at the Wheatley Education Campus in Washington. The interagency project, 21st Century Community Learning Centers, aims to engage students in science, technology, engineering, and math (STEM) education during after-school hours.
During the event, media will have the opportunity to learn about the STEM collaboration, hear remarks from leadership, and have one-on-one interviews with NASA and Education Department officials upon request. Additionally, students will have the opportunity to engage in educational activities, as well as participate in an engineering design challenge.
Officials providing remarks at the event include:
Kris Brown, deputy associate administrator, NASA’s Office of STEM Engagement, Headquarters in Washington Cindy Marten, deputy secretary, U.S. Department of Education Media interested in covering the event must RSVP no later than Friday, Sept. 20, to Abbey Donaldson: abbey.a.donaldson@nasa.gov.
Through the project, NASA’s Glenn Research Center in Cleveland and the Education Department will align resources to provide STEM activities, professional development, and funding for after-school programs nationwide. NASA will offer staff training, continuous program support, and opportunities for students to engage with NASA scientists and engineers. The initiative also will include student activities that demonstrate practical applications of STEM concepts.
In May 2023, NASA and the Education Department signed a Memorandum of Understanding, strengthening the collaboration between the two agencies, and expanding efforts to increase access to high-quality STEM and space education to students and schools across the nation. NASA Glenn signed a follow-on Space Act Agreement in 2024 to support the 21st Century Community Learning Centers.

JAXA (Japan Aerospace Exploration Agency) researchers examined the structures of four titanium-based compounds solidified in levitators in microgravity and on the ground and found that the internal microstructures were generally similar. These results could support development of new materials for use in space manufacturing.
To produce glass or metal alloys on Earth, raw materials are placed into a container and heated. But reactions between the container and the materials can cause imperfections. The JAXA Electrostatic Levitation Furnace can levitate, melt, and solidify materials without a container. The facility enables measurement of the thermophysical properties of high temperature melts and could accelerate development of innovative materials such as heat resistant ceramics for use in the aerospace and energy industries.
JAXA (Japan Aerospace Exploration Agency) astronaut Akihiko Hoshide works with the Electrostatic Levitation Furnace.European Space Agency/Thomas Pesquet Satellite 3D imaging of a Peruvian tropical forest demonstrated that measuring leaf traits with remote sensing may provide more accurate predictions of biomass production than structure data such as tree height. Carbon stored or sequestered in forests can help offset emissions that cause climate change, and improved estimates of tropical forest biomass could allow researchers to better evaluate these ecosystems and their offset contributions.
Global Ecosystem Dynamics Investigation (GEDI) provides high-resolution global observations of Earth’s forests and topography. These observations provide information on carbon and water cycling processes, biodiversity, and habitat, including quantifying carbon stored in vegetation and the potential for future carbon storage. The researchers suggest that estimates of tropical forest biomass could be further improved with data from new satellite missions and by integrating GEDI with dynamic vegetation models that include trait data.

The refrigerator-sized Global Ecosystem Dynamics Investigation instrument on the exterior of the International Space Station. NASA/Nick Hague Research indicates that refractive eye surgery is safe, effective, and suitable for astronauts. The study documented stable vision in two astronauts who, a few years prior to flight, underwent photorefractive keratectomy (PRK) and laser-assisted in situ keratomileusis (LASIK), respectively. These visual correction procedures can reduce the logistical complications of wearing glasses or contact lenses in space.
International Space Station Medical Monitoring collects health data from crew members before, during, and after spaceflight. The medical evaluation requirements, including vision assessment, apply to all crew members and are part of efforts by all international partners to maintain crew health, ensure mission success, and enable crew members to return to normal life on Earth after their missions.
NASA astronauts Terry Virts (bottom) and Scott Kelly (top) perform eye exams as part of ongoing studies into crew vision health. NASA JAXA researchers report that accurately assessing the velocity of airflow in front of a spreading flame makes it possible to predict the flammability of thin, flat materials in microgravity. These results mean it could be possible to use ground tests to predict the flammability of solid materials and thus ensure fire safety in spacecraft and space habitations.
The JAXA Fundamental Research on International Standard of Fire Safety in Space – Base for Safety of Future Manned Missions (FLARE) investigation tested the flammability of various solid materials in different configurations, including filter paper. Microgravity significantly affects combustion phenomena such as the spread of flame over solid materials; while flames cannot spread over solid materials under low-speed oxygen flow in Earth’s gravity, they can in microgravity due to the lack of buoyancy. Testing of the flammability of materials for spacecraft previously has not considered the effect of gravity, and results from this investigation could address this issue, significantly improving fire safety on future exploration missions.
