Manuel Retana arrived in the U.S. at 15 years old, unable to speak English and with nothing but a dream and $200 in his pocket. Now, he plays a crucial role implementing life support systems on spacecraft that will carry humans to the Moon and, eventually, Mars—paving the way for the next frontier of space exploration.
A project manager for NASA’s Johnson Space Center Life Support Systems Branch in Houston, Retana helps to ensure astronaut safety aboard the International Space Station and for future Artemis missions. His work involves tracking on-orbit technical issues, managing the cost and schedule impacts of flight projects, and delivering emergency hardware.
Manuel Retana stands in front of NASA’s Space Launch System rocket at Kennedy Space Center in Florida. One of his most notable achievements came during the qualification of the Orion Smoke Eater Filter for the Artemis II and III missions. The filter is designed to remove harmful gases and particulates from the crew cabin in the event of a fire inside the spacecraft. Retana was tasked with creating a cost-effective test rig – a critical step for making the filter safe for flight.
Retana’s philosophy is simple: “Rockets do not build themselves. People build rockets, and your ability to work with people will define how well your rocket is built.”
Throughout his career, Retana has honed his soft skills—communication, leadership, collaboration, and conflict resolution—to foster an environment of success.
Retana encourages his colleagues to learn new languages and share their unique perspectives. He even founded NASA’s first Mariachi ensemble, allowing him to share his cultural heritage in the workplace.
He believes diversity of thought is a key element in solving complex challenges as well as creating an environment where everyone feels comfortable sharing their perspectives.
“You need to be humble and have a willingness to always be learning,” he said. “What makes a strong team is the fact that not everyone thinks the same way.”
Manuel Retana, center, performs with the Mariachi Ensemble group at NASA’s Johnson Space Center in Houston. For the future of space exploration, Retana is excited about the democratization of space, envisioning a world where every country has the opportunity to explore. He is eager to see humanity reach the Moon, Mars, and beyond, driven by the quest to answer the universe’s most enigmatic questions.
To the Artemis Generation, he says, “Never lose hope, and it is never too late to start following your dreams, no matter how far you are.”

Preparations for Next Moonwalk Simulations Underway (and Underwater)
This bar graph shows GISTEMP summer global temperature anomalies for 2023 (shown in yellow) and 2024 (shown in red). June through August is considered meteorological summer in the Northern Hemisphere. The white lines indicate the range of estimated temperatures. The warmer-than-usual summers continue a long-term trend of warming, driven primarily by human-caused greenhouse gas emissions. NASA/Peter Jacobs The agency also shared new state-of-the-art datasets that allow scientists to track Earth’s temperature for any month and region going back to 1880 with greater certainty.
August 2024 set a new monthly temperature record, capping Earth’s hottest summer since global records began in 1880, according to scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York. The announcement comes as a new analysis upholds confidence in the agency’s nearly 145-year-old temperature record.
June, July, and August 2024 combined were about 0.2 degrees Fahrenheit (about 0.1 degrees Celsius) warmer globally than any other summer in NASA’s record — narrowly topping the record just set in 2023. Summer of 2024 was 2.25 F (1.25 C) warmer than the average summer between 1951 and 1980, and August alone was 2.34 F (1.3 C) warmer than average. June through August is considered meteorological summer in the Northern Hemisphere.
“Data from multiple record-keepers show that the warming of the past two years may be neck and neck, but it is well above anything seen in years prior, including strong El Niño years,” said Gavin Schmidt, director of GISS. “This is a clear indication of the ongoing human-driven warming of the climate.”
NASA assembles its temperature record, known as the GISS Surface Temperature Analysis (GISTEMP), from surface air temperature data acquired by tens of thousands of meteorological stations, as well as sea surface temperatures from ship- and buoy-based instruments. It also includes measurements from Antarctica. Analytical methods consider the varied spacing of temperature stations around the globe and urban heating effects that could skew the calculations.
The GISTEMP analysis calculates temperature anomalies rather than absolute temperature. A temperature anomaly shows how far the temperature has departed from the 1951 to 1980 base average.
New assessment of temperature record
The summer record comes as new research from scientists at the Colorado School of Mines, National Science Foundation, the National Atmospheric and Oceanic Administration (NOAA), and NASA further increases confidence in the agency’s global and regional temperature data.
“Our goal was to actually quantify how good of a temperature estimate we’re making for any given time or place,” said lead author Nathan Lenssen, a professor at the Colorado School of Mines and project scientist at the National Center for Atmospheric Research (NCAR).
This visualization of GISTEMP monthly temperatures with the seasonal cycle derived from the Global Modeling and Assimilation Office’s MERRA-2 model compares 2023 (in red) and 2024 (in purple), with a transparent ribbon around each indicating the confidence intervals from the new GISTEMP uncertainty calculation. The white lines show monthly temperatures from the years 1961 to 2022. June, July, and August 2024 combined were about 0.2 degrees Fahrenheit (about 0.1 degrees Celsius) warmer globally than any other summer in NASA’s record — narrowly topping the record set in 2023.NASA/Peter Jacobs/Katy Mersmann The researchers affirmed that GISTEMP is correctly capturing rising surface temperatures on our planet and that Earth’s global temperature increase since the late 19th century — summer 2024 was about 2.7 F (1.51 C) warmer than the late 1800s — cannot be explained by any uncertainty or error in the data.
The authors built on previous work showing that NASA’s estimate of global mean temperature rise is likely accurate to within a tenth of a degree Fahrenheit in recent decades. For their latest analysis, Lenssen and colleagues examined the data for individual regions and for every month going back to 1880.
Estimating the unknown
Lenssen and colleagues provided a rigorous accounting of statistical uncertainty within the GISTEMP record. Uncertainty in science is important to understand because we cannot take measurements everywhere. Knowing the strengths and limitations of observations helps scientists assess if they’re really seeing a shift or change in the world.
The study confirmed that one of the most significant sources of uncertainty in the GISTEMP record is localized changes around meteorological stations. For example, a previously rural station may report higher temperatures as asphalt and other heat-trapping urban surfaces develop around it. Spatial gaps between stations also contribute some uncertainty in the record. GISTEMP accounts for these gaps using estimates from the closest stations.
Previously, scientists using GISTEMP estimated historical temperatures using what’s known in statistics as a confidence interval — a range of values around a measurement, often read as a specific temperature plus or minus a few fractions of degrees. The new approach uses a method known as a statistical ensemble: a spread of the 200 most probable values. While a confidence interval represents a level of certainty around a single data point, an ensemble tries to capture the whole range of possibilities.
The distinction between the two methods is meaningful to scientists tracking how temperatures have changed, especially where there are spatial gaps. For example: Say GISTEMP contains thermometer readings from Denver in July 1900, and a researcher needs to estimate what conditions were 100 miles away. Instead of reporting the Denver temperature plus or minus a few degrees, the researcher can analyze scores of equally probable values for southern Colorado and communicate the uncertainty in their results.
What does this mean for recent heat rankings?
Every year, NASA scientists use GISTEMP to provide an annual global temperature update, with 2023 ranking as the hottest year to date.
Other researchers affirmed this finding, including NOAA and the European Union’s Copernicus Climate Change Service. These institutions employ different, independent methods to assess Earth’s temperature. Copernicus, for instance, uses an advanced computer-generated approach known as reanalysis.
The records remain in broad agreement but can differ in some specific findings. Copernicus determined that July 2023 was Earth’s hottest month on record, for example, while NASA found July 2024 had a narrow edge. The new ensemble analysis has now shown that the difference between the two months is smaller than the uncertainties in the data. In other words, they are effectively tied for hottest. Within the larger historical record the new ensemble estimates for summer 2024 were likely 2.52-2.86 degrees F (1.40-1.59 degrees C) warmer than the late 19th century, while 2023 was likely 2.34-2.68 degrees F (1.30-1.49 degrees C) warmer.

For some people, working for NASA is a lifelong dream. For others, it is an interesting and perhaps unexpected opportunity that comes up at just the right time and place.
Everything from family ties and influential teachers to witnessing human spaceflight history and enjoying sci-fi entertainment has helped bring people of all backgrounds together at NASA’s Johnson Space Center in Houston. Several of them recently shared their inspiration to join the NASA team.
***
“As a kid, I always had my head up looking at the stars. I loved astronomy and seeing videos of humans walking on the Moon fascinated me! I wanted to be the first female to walk on the Moon. When Star Wars came out, I wanted to build my own R2-D2 that could explore the galaxies. I was curious how things worked (so I could build a robot) and a cousin told me about engineering. That was the name for what I wanted to do! So, I went to the High School for Engineering Professions in Houston. The guidance counselor there told me about an opportunity to apply for a summer internship with NASA as a junior. I got in and I’ve worked with NASA as much as I could since I was 16 years old – internships and full-time positions. I may not get the chance to be an astronaut and walk on the Moon, but I know I will play a role in helping achieve that dream for another female and a person of color!”
– Alicia Baker, engineering project manager for Portable Life Support System test support, JSC Engineering, Technology, and Science (JETS) Contract

I went to take your kid to work day and got to stand in front of a booster engine. I’ve wanted to work in the space industry ever since. I almost didn’t enter the field after getting my aerospace degree, but I was fortunate to take an Intro to Human Spaceflight class during my last quarter of college. Without that class and the professor (who had worked at Johnson) I wouldn’t be here today. I’m so glad my path led me here. Johnson is such a great place to be, and I can look back and tell little Margaret that we did it!”

NASA/Josh Valcarcel “I didn’t think I would ever work for NASA. But multiple professors in college encouraged me to challenge myself and do some space research. I realized that it was something that I was very passionate about. Thanks to my research work for the Europa Clipper as an undergraduate student, I got my first internship at NASA and subsequently an offer to join the Pathways Program. Now I am part of a small group of engineers that solve entry, descent, and landing problems for multiple missions on Earth, the Moon, and Mars.”

“Dad would take me to the viewing room of the original Mission Operations Control Room (MOCR) during the Apollo era. He was one of the people supporting MOCR in the Staff Support Room. I have worked at Johnson for 27 years [as a contractor] for Lockheed Martin, Hamilton Sundstrand, and Jacobs Technology.”
– David Fanelli, software engineer, Energy Systems Test Area
“In early 1969, when I was a boy, my uncle visited the Johnson Space Center and brought back astronaut and mission photos of the recently completed Apollo 8 lunar orbiting mission. Those photos, coupled with a Saturn V rocket model I assembled, and the Time Life records and books about the Apollo space program my parents purchased for me, sparked my imagination. I knew I wanted to work for NASA one day. It wasn’t until many years later that that dream became a reality, when I joined NASA’s co-op program for college students during my second attempt to become an aeronautical engineer. After I graduated college, I began working full time as a civil servant engineer at Johnson.”

“I remember watching Star Trek and Star Wars as a kid with my dad. I found some of his college notes in a box one day and thought the small, neat print on graph paper pads was really pretty. He went to the University of Texas at Austin to study astrophysics and engineering, but he never got to finish. Fast forward to 2022 and I find myself in Houston for an unknown amount of time, so I decided to go out and make some friends. I met a woman at a Geeky Game Night, and I learned that she was a food scientist at NASA! After talking some more, she told me to send her my resume. Later that week I received a call to set up an interview. I’m still in awe of how that one chance connection led me to my childhood dream of working at NASA.”
– Kristin Dillon, document/IT specialist, Space Food Systems Laboratory
“I grew up in a small agricultural village in India. My first introduction to spaceflight was reading Russian cosmonauts’ translated accounts of the Apollo-Soyuz Test Project as a young girl. I am still not sure whether my father picked that book for me on a whim or with a grand dream for his daughter, but it certainly had me hooked. However, I found my true calling to make human spaceflight safer and more efficient after witnessing the Columbia mishap. India, at the time, did not have a human spaceflight program. Thus started a 20-year-long grand adventure of seeking opportunities, pursuing them, immigrating to the United States, and finding my path to NASA, which culminated in a Pathways internship at Johnson.”

NASA Summer Camp Inspires Future Climate Leaders
From July 15-19, 2024, the Coastal Equity and Resilience Hub at the Georgia Institute of Technology collaborated with the University of Georgia (UGA) Marine Extension and Georgia Sea Grant to host a week-long NASA Sea Level Changemakers Summer Camp. The camp introduced 14 rising 7th-8th graders to how coastal areas are changing due to sea level rise. Set at the UGA Marine Education Center and Aquarium on Skidaway Island, the camp offered students hands-on activities and outdoor educational experiences, where they analyzed real data collected by NASA scientists and learned about community adaptations to flooding. Students interacted with experts from NASA’s Jet Propulsion Laboratory, UGA, and Georgia Tech, gaining insights into satellite observations, green infrastructure, environmental sensors, and careers related to sea level rise. The camp also included a visit to the Pin Point Heritage Museum, where students engaged with leaders from the historic Gullah Geechee community of Pin Point. The camp concluded with a boat trip to Wassaw Island, where students observed the effects of sea level rise on an undeveloped barrier island and compared these observations with earlier findings from urban environments. Funding from the NASA’s Science Activation Program and its Sea Level Education, Awareness, and Literacy (SEAL) team ensured that the camp was accessible to all students, eliminating financial barriers for groups traditionally underrepresented in STEM education.
“This investment from NASA has provided an amazing opportunity for youth in coastal Georgia to utilize NASA data and resources on a critical issue affecting their communities,” said Jill Gambill, executive director of the Coastal Equity and Resilience (CEAR) Hub at Georgia Tech. “They have more confidence now in their knowledge of sea level rise and potential solutions.”
The Sea Level Education, Awareness, and Literacy (SEAL) team is supported by NASA under cooperative agreement award number NNH21ZDA001N-SCIACT and is part of NASA’s Science Activation Portfolio.
