Astrophysics Science Video Producer – Goddard Space Flight Center
Growing up in Detroit with a camera in her hand, Sophia Roberts — now an award-winning astrophysics science video producer—never imagined that one day her path would wind through clean rooms, vacuum chambers, and even a beryllium mine. But framing the final frontier sometimes requires traveling through some of Earth’s less-explored corners.
Sophia Roberts is an astrophysics Science video producer at NASA’s Goddard Space Flight Center in Greenbelt, Md. She films space hardware assembly and explains complicated topics, weaving science and art together.Credit: Courtesy of Sophia Roberts Sophia received her first camera from her father, a photography enthusiast, when she was just five or six years old. “I’ve basically been snapping away ever since!” she says.
With a natural curiosity and enthusiasm for science, Sophia pursued a degree in biology at Oberlin College in Ohio. There, she discovered that she could blend her two passions.
“I often lingered in lab sessions, not to finish an experiment but to photograph it,” Sophia says. “I had an epiphany at the beginning of class one day, which always opened with clips from BBC nature documentaries. I decided right then that I would be one of the people who make those videos one day.”
Part of Sophia’s role currently involves documenting NASA’s Nancy Grace Roman Space Telescope, which is taking shape and being tested at NASA Goddard. She captured a cosmic selfie while photographing the telescope’s primary mirror, which was designed and built by L3Harris Technologies in Rochester, New York, before it was integrated with other components.Credit: NASA/Sophia Roberts She initially thought that meant wildlife filmmaking—perched in a blind on a mountainside, waiting hours for an animal to appear. That dream led her to Montana State University, where she learned to blend scientific rigor with visual storytelling through their science and natural history filmmaking master’s program.
While completing her degree, Sophia worked as a traveling presenter for the Montana Space Grant Consortium. “I was mainly giving presentations about NASA missions and showing kids beautiful images of space,” she says. “That was my first true introduction to NASA. I loved being able to watch the children’s eyes light up when they saw what’s out there in space.”
Sophia then completed an internship at the Smithsonian’s National Museum of Natural History while completing her thesis. Once she graduated, she landed a year-long fellowship at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, as an Earth science news fellow. In this role, she focused on packaging up stories through satellite imagery and explanations.

“Webb is one of my great loves in life,” she says. “I learned to negotiate with engineers for the perfect shot, navigate NASA’s protocols, and work with mission partners. I only spent five years on Webb, but it feels like it was half my life. Still—it was everything.”
That mission took her to some unforgettable places, like a mine in Delta, Utah, where raw material for Webb’s mirrors was unearthed. “It was this giant, spiral pit where they were mining beryllium at just 0.02% concentration,” Sophia says. The process was as otherworldly as the location.
In 2021, Sophia traveled to Delta, Utah to capture behind-the-scenes footage of raw material for the James Webb Space Telescope’s mirrors being unearthed.

Once Webb launched, Sophia pivoted to covering many of NASA’s smaller astrophysics missions along with the upcoming Nancy Grace Roman Space Telescope. These days, she can often be found gowned up in a “bunny suit” in the largest clean room at Goddard to document space telescope assembly, or in a studio recording science explanations.

For Sophia, the process is often as exhilarating as the result. “I love venturing out to remote places where science is being done,” she says. “I’d love to film a balloon launch in Antarctica someday!”

Featuring never-before-seen footage, Cosmic Dawn offers an unprecedented glimpse into Webb’s assembly, testing, and launch. Credit: NASA/Joel Kowsky To others who dream of pursuing a similar career, Sophia recommends diving in headfirst. “With cameras readily available and free online platforms, it’s never been easier to get into the media,” she says. “You just have to be careful to research your topic and sources, making sure you really know what you’re sharing and understand that science is always evolving as we learn more.” And Sophia emphasizes how important storytelling is for conveying information, especially when it’s as complex as astrophysics. “Studying science is wonderful, but I also think helping people visualize it is magical.”

Preparations for Next Moonwalk Simulations Underway (and Underwater)
In addition to drilling rock core samples, the science team has been grinding its way into rocks to make sense of the scientific evidence hiding just below the surface.
NASA’s Perseverance rover uses an abrading bit to get below the surface of a rocky out-crop nicknamed “Kenmore” on June 10. The eight images that make up this video were taken approximately one minute apart by one of the rover’s front hazard-avoidance cameras. NASA/JPL-Caltech On June 3, NASA’s Perseverance Mars rover ground down a portion of a rock surface, blew away the resulting debris, and then went to work studying its pristine interior with a suite of instruments designed to determine its mineralogic makeup and geologic origin. “Kenmore,” as nicknamed by the rover science team, is the 30th Martian rock that Perseverance has subjected to such in-depth scrutiny, beginning with drilling a two-inch-wide (5-centimeter-wide) abrasion patch.
“Kenmore was a weird, uncooperative rock,” said Perseverance’s deputy project scientist, Ken Farley from Caltech in Pasadena, California. “Visually, it looked fine — the sort of rock we could get a good abrasion on and perhaps, if the science was right, perform a sample collection. But during abrasion, it vibrated all over the place and small chunks broke off. Fortunately, we managed to get just far enough below the surface to move forward with an analysis.”
The science team wants to get below the weathered, dusty surface of Mars rocks to see important details about a rock’s composition and history. Grinding away an abrasion patch also creates a flat surface that enables Perseverance’s science instruments to get up close and personal with the rock.
This close-up view of an abrasion showing distinctive “tool marks” created by the Perseverance’s abrading bit was acquired on June 5. The image was taken from approximately 2.76 inches (7 centimeters) away by the rover’s WATSON imager. NASA/JPL-Caltech/MSSS Perseverance’s gold-colored abrading bit takes center stage in this image of the rover’s drill taken by the Mastcam-Z instrument on Aug. 2, 2021, the 160th day of the mission to Mars.NASA/JPL-Caltech/ASU/MSSS Time to Grind
NASA’s Mars Exploration Rovers, Spirit and Opportunity, each carried a diamond-dust-tipped grinder called the Rock Abrasion Tool (RAT) that spun at 3,000 revolutions per minute as the rover’s robotic arm pushed it deeper into the rock. Two wire brushes then swept the resulting debris, or tailings, out of the way. The agency’s Curiosity rover carries a Dust Removal Tool, whose wire bristles sweep dust from the rock’s surface before the rover drills into the rock. Perseverance, meanwhile, relies on a purpose-built abrading bit, and it clears the tailings with a device that surpasses wire brushes: the gaseous Dust Removal Tool, or gDRT.
“We use Perseverance’s gDRT to fire a 12-pounds-per-square-inch (about 83 kilopascals) puff of nitrogen at the tailings and dust that cover a freshly abraded rock,” said Kyle Kaplan, a robotic engineer at NASA’s Jet Propulsion Laboratory in Southern California. “Five puffs per abrasion — one to vent the tanks and four to clear the abrasion. And gDRT has a long way to go. Since landing at Jezero Crater over four years ago, we’ve puffed 169 times. There are roughly 800 puffs remaining in the tank.” The gDRT offers a key advantage over a brushing approach: It avoids any terrestrial contaminants that might be on a brush from getting on the Martian rock being studied.

This video captures a test of Perseverance’s Gaseous Dust Removal Tool (gDRT) in a vacuum chamber at NASA’s Jet Propulsion Laboratory in August 2020. The tool fires puffs of nitrogen gas at the tailings and dust that cover a rock after it has been abraded by the rover.NASA/JPL-Caltech Having collected data on abraded surfaces more than 30 times, the rover team has in-situ science (studying something in its original place or position) collection pretty much down. After gDRT blows the tailings away, the rover’s WATSON (Wide Angle Topographic Sensor for Operations and eNgineering) imager (which, like gDRT, is at the end of the rover’s arm) swoops in for close-up photos. Then, from its vantage point high on the rover’s mast, SuperCam fires thousands of individual pulses from its laser, each time using a spectrometer to determine the makeup of the plume of microscopic material liberated after every zap. SuperCam also employs a different spectrometer to analyze the visible and infrared light that bounces off the materials in the abraded area.
“SuperCam made observations in the abrasion patch and of the powdered tailings next to the patch,” said SuperCam team member and “Crater Rim” campaign science lead, Cathy Quantin-Nataf of the University of Lyon in France. “The tailings showed us that this rock contains clay minerals, which contain water as hydroxide molecules bound with iron and magnesium — relatively typical of ancient Mars clay minerals. The abrasion spectra gave us the chemical composition of the rock, showing enhancements in iron and magnesium.”
Later, the SHERLOC (Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals) and PIXL (Planetary Instrument for X-ray Lithochemistry) instruments took a crack at Kenmore, too. Along with supporting SuperCam’s discoveries that the rock contained clay, they detected feldspar (the mineral that makes much of the Moon brilliantly bright in sunlight). The PIXL instrument also detected a manganese hydroxide mineral in the abrasion — the first time this type of material has been identified during the mission.
With Kenmore data collection complete, the rover headed off to new territories to explore rocks — both cooperative and uncooperative — along the rim of Jezero Crater.
“One thing you learn early working on Mars rover missions is that not all Mars rocks are created equal,” said Farley. “The data we obtain now from rocks like Kenmore will help future missions so they don’t have to think about weird, uncooperative rocks. Instead, they’ll have a much better idea whether you can easily drive over it, sample it, separate the hydrogen and oxygen contained inside for fuel, or if it would be suitable to use as construction material for a habitat.”
Long-Haul Roving
On June 19 (the 1,540th Martian day, or sol, of the mission), Perseverance bested its previous record for distance traveled in a single autonomous drive, trekking 1,348 feet (411 meters). That’s about 210 feet (64 meters) more than its previous record, set on April 3, 2023 (Sol 753). While planners map out the rover’s general routes, Perseverance can cut down driving time between areas of scientific interest by using its self-driving system, AutoNav.
“Perseverance drove 4½ football fields and could have gone even farther, but that was where the science team wanted us to stop,” said Camden Miller, a rover driver for Perseverance at JPL. “And we absolutely nailed our stop target location. Every day operating on Mars, we learn more on how to get the most out of our rover. And what we learn today future Mars missions won’t have to learn tomorrow.”

What does it take to gaze through time to our universe’s very first stars and galaxies?
NASA answers this question in its new documentary, “Cosmic Dawn: The Untold Story of the James Webb Space Telescope.” The agency’s original documentary, which chronicles the story of the most powerful telescope ever deployed in space, was released Wednesday, June 11.
Cosmic Dawn offers an unprecedented glimpse into the delicate assembly, rigorous testing, and triumphant launch of NASA’s James Webb Space Telescope. The documentary showcases the complexity involved in creating a telescope capable of peering billions of years into the past.
Cosmic Dawn is now available for streaming on NASA’s YouTube, NASA+, and select local theaters. The trailer is available on NASA+ and YouTube.
Relive the pitfalls and the triumphs of the world’s most powerful space telescope—from developing the idea of an impossible machine to watching with bated breath as it unfolded, hurtling through space a million miles away from Earth. Watch the Documentary on YouTube The film features never-before-seen footage captured by the Webb film crew, offering intimate access to the challenges and triumphs faced by the team at NASA’s Goddard Space Flight Center in Greenbelt, Maryland — the birthplace of Webb.
“At NASA, we’re thrilled to share the untold story of our James Webb Space Telescope in our new film ‘Cosmic Dawn,’ celebrating not just the discoveries, but the extraordinary people who made it all happen, for the benefit of humanity,” said Rebecca Sirmons, head of NASA+ at the agency’s headquarters in Washington.
From its vantage point more than a million miles from Earth and a massive sunshield to block the light of our star, Webb’s First Deep Field the deepest and sharpest infrared images of the universe that the world had seen.
Webb’s images have dazzled people around the globe, capturing the very faint light of the first stars and galaxies that formed more than 13.5 billion years ago. These are baby pictures from an ancient past when the first objects were turning on and emitting light after the Big Bang. Webb has also given us new insights into black holes, planets both inside and outside of our own solar system, and many other cosmic phenomena.
Webb was a mission that was going to be spectacular whether that was good or bad — if it failed or was successful. It was always going to make history

NASA’s biggest and most powerful space telescope was also its most technically complicated to build. It was harder still to deploy, with more than 300 critical components that had to deploy perfectly. The risks were high in this complicated dance of engineering, but the rewards were so much higher.
“Webb was a mission that was going to be spectacular whether that was good or bad — if it failed or was successful,” said video producer Sophia Roberts, who chronicled the five years preceding Webb’s launch. “It was always going to make history.”
NASA scientists like Nobel Laureate Dr. John Mather conceived Webb to look farther and deeper into origins of our universe using cutting edge infrared technology and massive mirrors to collect incredibly rich information about our universe, from the light of the first galaxies to detailed images of planets in our own solar system.
To achieve this goal, NASA and its partners faced unprecedented hurdles.
Webb’s development introduced questions that no one had asked before. How do you fit a telescope with the footprint of a tennis court into a rocket? How do you clean 18 sensitive mirrors when a single scratch could render them inoperable? How do you maintain critical testing while hurricane stormwater pours through ceilings?

“There was nothing easy about Webb at all,” said Webb project manager Bill Ochs. “I don’t care what aspect of the mission you looked at.”
Viewers will experience a one-of-a-kind journey as NASA and its partners tackle these dilemmas — and more — through ingenuity, teamwork, and unbreakable determination.
“The inspiration of trying to discover something — to build something that’s never been built before, to discover something that’s never been known before — it keeps us going,” Mather said. “We are pleased and privileged in our position here at NASA to be able to carry out this [purpose] on behalf of the country and the world.”
Bound by NASA’s 66-year commitment to document and share its work with the public, Cosmic Dawn details every step toward Webb’s launch and science results.
