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!”

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!”

Her sons – who were studying engineering in college – came and launched model rockets for us. I knew from that point on that I wanted to work at NASA when I grew up.”

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.”

Hubble Traces Star Formation in a Nearby Nebula
NASA, ESA, and L. C. Johnson (Northwestern University); Image Processing: Gladys Kober (NASA/Catholic University of America) NGC 261 blooms a brilliant ruby red against a myriad of stars in this new image from NASA’s Hubble Space Telescope. Discovered on Sept. 5, 1826 by Scottish astronomer James Dunlop, this nebula is located in one of the Milky Way’s closest galactic companions, the Small Magellanic Cloud (SMC). The ionized gas blazing from within this diffuse region marks NGC 261 as an emission nebula. It is home to numerous stars hot enough to irradiate surrounding hydrogen gas, causing the cloud to emit a pinkish-red glow.
This inset image shows the location of NGC 261 within the Small Magellanic Cloud. NASA, ESA, L. C. Johnson (Northwestern University), and ESO/VISTA VMC; Image Processing: Gladys Kober (NASA/Catholic University of America) Hubble turned its keen eye toward NGC 261 to investigate how efficiently stars form in molecular clouds, which are extremely dense and compact regions of gas and dust. These clouds often consist of large amounts of molecular hydrogen — cold areas where most stars form. However, measuring this raw fuel of star formation in stellar nurseries is a challenge because molecular hydrogen doesn’t radiate easily. Since it is difficult to detect, scientists instead trace other molecules present in the molecular clouds.
The SMC hosts a gas-rich environment of young stars along with trace amounts of carbon monoxide (CO), a chemical correlated with hydrogen and often used to identify the presence of such clouds. Using the Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3), Hubble imaged these stars in the southwest portion of the SMC where NGC 261 resides. The combined power of ACS and WFC3 allowed scientists to closely examine the nebula’s star-forming properties through its CO content at optical and near-infrared wavelengths. This research helps astronomers better understand how stars form in our home galaxy and others in our galactic neighborhood.

In this image of the Serpens Nebula from NASA’s James Webb Space Telescope, astronomers found a grouping of aligned protostellar outflows within one small region (the top left corner). Serpens is a reflection nebula, which means it’s a cloud of gas and dust that does not create its own light, but instead shines by reflecting the light from stars close to or within the nebula.NASA, ESA, CSA, STScI, Klaus Pontoppidan (NASA-JPL), Joel Green (STScI) NASA’s James Webb Space Telescope has captured a phenomenon for the very first time. The bright red streaks at top left of this June 20, 2024, image are aligned protostar outflows – jets of gas from newborn stars that all slant in the same direction.
This image supports astronomers’ assumption that as clouds collapse to form stars, the stars will tend to spin in the same direction. Previously, the objects appeared as blobs or were invisible in optical wavelengths. Webb’s sensitive infrared vision was able to pierce through the thick dust, resolving the stars and their outflows.
