Three employees from NASA’s Langley Research Center in Hampton, Virginia recently earned the Silver Snoopy award, a prestigious honor given to NASA employees and contractors across the agency for exceptional achievements related to spaceflight safety or mission success. Christopher Broadaway, Jeremy Shidner, and Sara Wilson received the awards during a ceremony held at the center on July 22. 

The Silver Snoopy award is given personally by NASA astronauts and is presented to less than one percent of the agency’s workforce annually. The award is one of several overseen by the Space Flight Awareness (SFA) Program at NASA. Established in 1963, the SFA Program is vital in ensuring quality and flight safety of America’s space program. The SFA Program works to highlight the individuals behind the success of NASA’s programs as well as motivate the next generation of innovators and cosmic explorers. 

Astronaut Tracy Dyson visited Langley to present the Silver Snoopy lapel pin and a framed Silver Snoopy certificate. Dyson flew aboard the space shuttle Endeavor on STS-118, served as flight engineer for Expedition 23/24, and conducted hundreds of hours of scientific investigations aboard the International Space Station for Expedition 70/71. She has spent a total of 373 days in space and dedicated over 23 hours to spacewalks. 

As a flight engineer with substantial experience, Dyson understands the importance of space flight safety.  

“Those who are receiving this award didn’t do it because they came nine to five and left. It’s not because it was just their job,” she said. “It’s because it’s their life, and our lives are safer and better for it.”

Silver Snoopy recipient and aerospace engineer Jeremey Shidner echoed Dyson’s perspective. 

“This level of trust is particularly profound because astronauts understand better than anyone the countless systems, procedures, and people that must work flawlessly for a mission to succeed,” he said. “When astronauts single someone out for recognition, it reflects their confidence that this person embodies the same commitment to excellence and safety that they themselves must maintain.” 

The prestigious award consists of a certificate of appreciation signed by Dyson, an authentication letter, and a miniature sterling silver lapel pin in the shape of the well-loved character Snoopy from the comic strip “Peanuts.” Each pin awarded has flown in space. The pins awarded to Langley’s recipients flew aboard STS-118.

Here are the three award recipients from Langley and their achievements: 

Christopher Broadaway: For exemplary support in assisting the Commercial Crew Program ensure safety and mission success in industry partners’ human spaceflight missions. 

Jeremy Shidner: For significant contributions to the Commercial Crew Program to ensure flight safety and mission success for Entry, Descent, and Landing. Collaborating closely with the Crew Flight Test team and Mission Operations Flight Dynamics Officers, he refined the simulation model to incorporate real pilot performance data, which resulted in increased entry accuracy, eliminating an elevated risk to crew safety. 

Sara R. Wilson: For engineering excellence in the application of advanced statistical tools and methods characterizing NASA’s human spaceflight missions. She also played a key role in developing standardized tests for advanced lunar spacesuit gloves, creating consistency in evaluating materials for extreme lunar environments.

As NASA Missions Study Interstellar Comet, Hubble Makes Size Estimate

At the center of the image is a comet that appears as a teardrop-shaped bluish cocoon of dust coming off the cometu2019s solid, icy nucleus and seen against a black background. The comet appears to be heading to the bottom left corner of the image. About a dozen short, light blue diagonal streaks are seen scattered across the image, which are from background stars that appeared to move during the exposure because the telescope was tracking the moving comet.
Hubble captured this image of the interstellar comet 3I/ATLAS on July 21, 2025, when the comet was 277 million miles from Earth. Hubble shows that the comet has a teardrop-shaped cocoon of dust coming off its solid, icy nucleus.

A team of astronomers has taken the sharpest-ever picture of the unexpected interstellar comet 3I/ATLAS using the crisp vision of NASA’s Hubble Space Telescope. Hubble is one of many missions across NASA’s fleet of space telescopes slated to observe this comet, together providing more information about its size and physical properties. While the comet poses no threat to Earth, NASA’s space telescopes help support the agency’s ongoing mission to find, track, and better understand near-Earth objects.

Hubble’s observations allow astronomers to more accurately estimate the size of the comet’s solid, icy nucleus. The upper limit on the diameter of the nucleus is 3.5 miles (5.6 kilometers), though it could be as small as 1,000 feet (320 meters) across, researchers report. Though the Hubble images put tighter constraints on the size of the nucleus compared to previous ground-based estimates, the solid heart of the comet presently cannot be directly seen, even by Hubble. Observations from other NASA missions including the James Webb Space Telescope, TESS (Transiting Exoplanet Survey Satellite), and the Neil Gehrels Swift Observatory, as well as NASA’s partnership with the W.M. Keck Observatory, will help further refine our knowledge about the comet, including its chemical makeup.

Hubble also captured a dust plume ejected from the Sun-warmed side of the comet, and the hint of a dust tail streaming away from the nucleus. Hubble’s data yields a dust-loss rate consistent with comets that are first detected around 300 million miles from the Sun. This behavior is much like the signature of previously seen Sun-bound comets originating within our solar system.

The big difference is that this interstellar visitor originated in some other solar system elsewhere in our Milky Way galaxy.

3I/ATLAS is traveling through our solar system at a staggering 130,000 miles (209,000 kilometers) per hour, the highest velocity ever recorded for a solar system visitor. This breathtaking sprint is evidence that the comet has been drifting through interstellar space for many billions of years. The gravitational slingshot effect from innumerable stars and nebulae the comet passed added momentum, ratcheting up its speed. The longer 3I/ATLAS was out in space, the higher its speed grew.

“No one knows where the comet came from. It’s like glimpsing a rifle bullet for a thousandth of a second. You can’t project that back with any accuracy to figure out where it started on its path,” said David Jewitt of the University of California, Los Angeles, science team leader for the Hubble observations.

The paper will be published in The Astrophysical Journal Letters. It is already available on Astro-ph.

New Evidence for Population of Wandering Space Relics

“This latest interstellar tourist is one of a previously undetected population of objects bursting onto the scene that will gradually emerge,” said Jewitt. “This is now possible because we have powerful sky survey capabilities that we didn’t have before. We’ve crossed a threshold.”

This comet was discovered by the NASA-funded Asteroid Terrestrial-impact Last Alert System (ATLAS) on July 1, 2025, at a distance of 420 million miles from the Sun. ATLAS is an asteroid impact early warning system developed by the University of Hawai’i. 

In the meantime, other NASA missions will provide new insight into this third interstellar interloper, helping refine our understanding of these objects for the benefit of all. 3I/ATLAS should remain visible to ground-based telescopes through September, after which it will pass too close to the Sun to observe, and is expected to reappear on the other side of the Sun by early December.

The Hubble Space Telescope has been operating for more than three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA (European Space Agency). NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope and mission operations. Lockheed Martin Space, based in Denver, also supports mission operations at Goddard. The Space Telescope Science Institute in Baltimore, which is operated by the Association of Universities for Research in Astronomy, conducts Hubble science operations for NASA.

Wade Sisler: Aficionado of Wonder Serving the Cosmos

Wade Sisler: Aficionado of Wonder Serving the Cosmos

Across 42 years at NASA, Wade Sisler — executive producer at NASA’s Goddard Space Flight Center in Greenbelt, Maryland—watched the edge of human knowledge progress. During that time, the tools for visualizing and communicating those discoveries evolved just as rapidly.

“I’ve spent my career surrounded by people with amazing curiosity and intellect, pursuing questions that could change the way we see the universe, both literally and metaphorically,” Sisler said.

From his start as a student photographer at NASA’s Ames Research Center in California’s Silicon Valley, Sisler ultimately became a creative force behind some of NASA’s most iconic science storytelling. He transitioned to videography when he realized the wonder and understanding the medium could convey.

“The fidelity of the story you could tell with pictures through video was so impactful,” he said. “It was just pure awe. So I gave up my Hasselblads, trading the sheer beauty of imagery for the much more powerful storytelling tools that came with the emerging field of video — specifically the ability to take the audience with you to experience the mission.”

From Space Frogs to the Eagle Nebula 

In the 1980s and ’90s, Sisler worked as a producer on a wide range of projects, translating complex research into short documentaries and educational broadcasts.

“We were helping people see things that had never been seen before, and showing them relationships that they never knew existed,” he said.

In one of his favorite early assignments, Sisler worked with astronaut Mae Jemison for a video project on space frogs. Jemison was studying how frog embryos develop in microgravity on the space shuttle. Sisler also had a hand in early virtual reality systems, producing one of the first videos depicting how VR could work.

Sisler eventually moved from NASA Ames to NASA Headquarters in Washington. There, he helped modernize NASA TV.

“They were shifting it from just mission-oriented content to a television news feed, exploring ideas to align with national news interests,” he said.

In one of his pilot stories, he produced a video and story news package about the Hubble Space Telescope’s observations of the Eagle Nebula.

“They handed me a 16-by-20-inch print of the Eagle Nebula right after Hubble imaged it,” he said. His team used a robotic camera to pan around the image while narration explained what viewers were seeing. “We wondered if we put that little microcosm of a story into a news feed, would anybody use it? And it ended up being used thousands and thousands of times, validating the NASA TV model with a bona fide science story and giving me a glimpse of the exciting stuff I could do.”

While at NASA Headquarters, Sisler also negotiated an IMAX agreement that led to new 3D films (including ones Sisler worked on, like the 1997 “Mission to Mir” and 2002 “Space Station 3D”). After a few years, he moved on to NASA’s Goddard Space Flight Center in Greenbelt, Maryland, in 1997 as an executive producer. Goddard’s communications team was small and had little experience in visual storytelling, so he joined the team to nurture its growth.

Science for the Senses 

In the late ’90s, Wade teamed up with NASA’s Scientific Visualization Studio (based at NASA Goddard) and lead visualizer Horace Mitchell to explore a new frontier in science storytelling. While NASA was already known for its iconic space imagery, much of its data deals with invisible phenomena or abstract processes that aren’t inherently visual. By bringing together scientists, artists, and producers, Sisler helped transform data into visualizations and animations for broader audiences.

“We had to invent ways of visualizing the invisible so meaning was more easily conveyed,” he said. “The result was stories that were not just newsworthy—they were often stunningly beautiful and showed the connections and workings of the Earth and universe in ways we had never seen before.”

The team had a breakout hit in 1998 with an El Niño visualization, which helped drive public understanding of the phenomenon. Sisler also helped launch a NASA Goddard program to link scientific experts with news stations around the world.

“We wanted to put the authentic voices of scientists in the chair to convey their sense of awe while telling people scientifically why it matters,” he said. “Pairing their voices with great visualizations was an unbeatable combination and that became the fundamental way we tell science stories.”

Sisler’s storytelling journey evolved into increasingly ambitious creative partnerships that brought NASA science to new cultural spaces. With “Cosmic Cycles,” a collaboration with the National Philharmonic, Wade helped create a program that paired music from a live symphony with high-resolution NASA imagery, inviting viewers to experience the celestial scenery emotionally, not just intellectually.

Instead of the NASA Goddard team creating a video to go along with music, “The composer drew inspiration from video produced by Goddard,” Sisler said. “It’s one of the best examples of science and art in mutual orbit.”

That blending of science and artistic expression reached a new scale in “Beyond the Light,” an art show developed with ARTECHOUSE and James Webb Space Telescope communications lead Laura Betz. Sisler linked artists with NASA scientists to turn cutting-edge astrophysics into a gallery-scale sensory experience. Most recently, Sisler championed a major documentary on Webb called “Cosmic Dawn.” The 1.5-hour film brings viewers on an unprecedented journey through Webb’s delicate assembly, rigorous testing, and triumphant launch.

Many of NASA’s flagship communication programs trace their roots to small teams that Sisler helped assemble and guide. He took a builder’s approach, rolling up his sleeves, testing ideas, and empowering others to scale them. From science storytelling and satellite media tours to the rise of NASA’s audio storytelling, Spanish-language content, Conceptual Image Laboratory animations, social media presence, and live broadcast programming, Sisler played a key role in turning bright ideas into enduring agency assets.

For each of these projects, Sisler worked behind the scenes as a creative force and a connector, bringing together filmmakers, animators, composers, scientists, engineers, astronauts, museum curators, data visualizers, and educators.

Lighting the Way

Despite many accolades, Sisler said his proudest accomplishment is the success of the internship program he has led for NASA Goddard’s Office of Communications.

“The thing that stays with me most is seeing where our former interns have landed,” he said. Many now lead their own programs within NASA, shaping the next generation of science storytelling from inside the agency. Others have taken their skills beyond NASA, contributing to science and technology literacy through media, education, and public engagement. “It’s been a privilege to help launch so many of these careers. I’ve always believed that when you combine mentorship, meaningful work, and a little creative freedom, you create a ripple effect that lasts for decades.”

Sisler’s own NASA journey began with a Pathways internship at NASA Ames while he was studying journalism at Baylor University in Texas. His work there drew him into visual storytelling, which led him to pursue photography, video, and science photography at the Rochester Institute of Technology in New York. As he alternated semesters between school and NASA Ames, he refined both his interests and his skills.

Sisler’s goal as an internship program coordinator was to help give the next generation of science communicators the same opportunity. He developed a communication “boot camp” to help interns develop their storytelling chops in many areas and figure out which were their favorites.

“All the interesting stuff happens at the intersections of people’s passions,” he said. “The best, most powerful thing I think I’ve done in my time at NASA is to help guide the next wave of science communicators. Seeing their success is the gift that keeps on giving.”

Written by Abigail Fraeman, Deputy Project Scientist at NASA’s Jet Propulsion Laboratory

Earth planning date: Wednesday, Aug. 6, 2025.

Today was a very special day for Curiosity as the rover celebrated the start of a 14th year on Mars. Curiosity is currently exploring the mysterious boxwork formations. On Monday, the rover positioned itself at the side of one of the ridges, where the team had spotted tantalizing hints of a complex network of razor-thin veins that may give insight into what is holding the ridges up, compared to the surrounding hollows

In this plan, the team will use the instruments on Curiosity’s arm and mast to investigate the geometry and composition of these veins to learn more about them. APXS and MAHLI will both observe “Repechón,” a loose block with dark-toned, mottled material exposed on top, as well as “Lago Poopó,” a bright, relatively clean vein network. MAHLI will also collect a side view of “Repechón.” ChemCam will use its laser to analyze two targets, “Vicguna,” a protruding vein edge with nodular texture, and “Ibare,” which has some exposed light-toned veins. Outside of the vein investigation, ChemCam’s telescopic RMI camera will observe layering in a nearby butte and the Mishe Mokwa feature, while Mastcam will take mosaics on “Cachiniba,” a broken block, “Yapacani,” the side of another large boxwork ridge, and “Llullaillaco,” a faraway feature that we imaged from a slightly different location in a previous plan. Additional environmental monitoring observations will round out the plan, followed by a straight-line drive to the east, to an area where several large boxwork ridges intersect that the team has been informally calling “the peace sign” because of its shape.

I usually get nostalgic around landing anniversaries, or “landiversaries,” and this year, I found myself looking back through pictures of landing night. One of my favorites shows me standing next to science team member Kirsten Siebach right after we received the first images from Curiosity. The two of us have the biggest, most excited grins on our faces. We were both graduate students at the time, and both of us were writing thesis chapters analyzing orbital data over regions we hoped to explore with Curiosity one day. I was studying a layer in Mount Sharp that contained hematite, and the team named this feature “Vera Rubin ridge” when Curiosity reached it in 2017. Kirsten, who is now a professor at Rice University, was focused on the boxwork structures, pondering how they formed and hypothesizing what they might tell us about the history of Martian habitability when we reached them.

Thirteen years later, I had another big grin on my face today, as I listened to Kirsten and our incredible science team members excitedly discussing Curiosity’s new images of these same boxwork structures. I was also filled with gratitude for the thousands of people it took to get us to this moment. It was the absolute best way to spend a landiversary.

Eight of 11 Expedition 73 crew members on the International Space Station enjoyed a light schedule on Wednesday following four busy days of Dragon departure and arrival activities for NASA’s SpaceX Crew-10 and Crew-11 missions. The other three orbital residents studied how the human body adapts to weightlessness, photographed crew operations, and maintained lab systems throughout the day.

Crew-11, with NASA astronauts Zena Cardman and Mike Fincke, JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui, and Roscosmos cosmonaut Oleg Platonov, is in its first week aboard the orbital outpost. The commercial crew joined Expedition 73 on Saturday, Aug.2, beginning their space research mission. With the exception of Platonov, they relaxed on Wednesday after an intense period of unpacking science experiments and cargo from their SpaceX Dragon spacecraft, familiarizing themselves with station hardware and procedures, and getting used to living and working in low Earth orbit.

First time orbital resident Platonov had a full day Wednesday with human research and keeping up life support maintenance. He attached acoustic sensors to his neck measuring the sound as he exhaled rapidly for a Roscosmos respiratory study. He also worked on oxygen and water systems throughout the station’s Roscosmos segment. Platonov kicked off his space studies at the beginning of the week wearing virtual reality goggles and responding to stimuli to observe how his balance and visual perception are adjusting to microgravity.

Four Expedition 73 crewmates, who have been orbiting Earth since March, are now handing over their mission responsibilities to the new arrivals and preparing to depart the orbital outpost no earlier than 12:05 p.m. EDT on Thursday. NASA astronauts Anne McClain and Nichole Ayers, along with JAXA astronaut Takuya Onishi and Roscosmos cosmonaut Kirill Peskov are preparing to return to Earth inside the Dragon they launched to the station in as Crew-10 members. The foursome cleared its schedule Wednesday taking time out for exercise to condition their bodies for return to Earth’s gravity, light maintenance duties, and quick Dragon computer configurations.

NASA Flight Engineer Jonny Kim, who is staying space until December, cleared his schedule on Wednesday having supported the Crew-10 and Crew-11 members since Saturday during their crew swap activities.

Also continuing their mission until the end of the year are new station Commander Sergey Ryzhikov and Flight Engineer Alexey Zubritsky, both from Roscosmos. They took turns on Wednesday wearing electrodes and the same virtual reality goggles Platonov wore earlier this week to test their sensory and balance adaption to weightlessness. Ryzhikov later partnered with Platonov and serviced the Elektron oxygen generator aboard the Zvezda service module. Zubritskiy photographed and videotaped the crew during the first half of his shift to document life aboard orbiting lab for mission controllers on Earth.
