NASA Langley’s “Stars, Stripes, and Supernovas – Symphony Under the Stars” event brought employees, families, and community members together for an evening filled with music, connection, and celebration.
Organizers planned the event, which took place July 16, to mark the 250th anniversary of the founding of the United States of America.
The evening featured a dynamic mix of performances from an orchestra that included NASA Langley employees and members of the Williamsburg Youth Orchestra, as well as smaller group performances from employees and special guest artist Karl Werne.

“It’s fun to bring people together, to share their diverse talents in order to create something that’s meaningful – and in this case something that was very beautiful too,” said Jennifer Kibler, deputy director of the Research Directorate at NASA Langley.
The orchestra played a selection of patriotic favorites and space-inspired pieces that highlighted the creativity and talent within the community. “America the Beautiful,” “God Bless America,” and “Jupiter, the Bringer of Jollity” from Gustav Holst’s orchestral suite “The Planets” were among the songs they performed.
The event, which also took place just one day before NASA Langley’s 109th birthday, served as a reminder of the spirit that defines the center—scientists, engineers, communicators, and staff coming together to celebrate not only NASA’s mission, but the people who make that mission possible.
“This was a big team effort,” said Nicole Oman, administrative management specialist with the Research Directorate. “It wouldn’t have been a success without the contributions of every single person.”

The Wabanaki people have a deep well of creation myths explaining the rocky coastlines of the Bay of Fundy, Downeast Maine, and Acadia National Park. Many involve Glooscap—a magical figure said to have floated down the Bay of Fundy in a stone canoe, sculpting coastal features by scraping the vessel across the landscape and scattering enormous boulders during battles with primordial beavers, frogs, moose, whales, and other gigantic animals.
Fewer Indigenous creation myths survive to explain the origins of the sandy and marshy shorelines of southern Maine and the rocky, indented coasts of the state’s Midcoast region. But the sharp contrast between the sandy shoals and beaches south of Portland and the rocky shoreline of promontories, headlands, and narrow peninsulas to the east—visible in the Landsat image above—has long drawn the attention of coastal geologists, whose scientific explanations on its origins abound.
The coastal transition reflects both differences in the underlying bedrock and the distribution of sediment left behind by the last glacial maximum, coastal geologists say. Southern Maine has broad deposits of sand, much of it sourced from rivers. The sandy beaches of Saco Bay, for instance, home to Maine’s longest contiguous beach and the state’s largest saltmarsh, received sediment from the weathering and breakdown of the White Mountains, with material transported to the coast largely by the Saco River, explained Peter Slovinsky, a geologist with the Maine Geological Survey. Waves and tides reworked these soft sediments over time, sculpting them into the arch-shaped embayed beaches and sprawling salt marshes found around Saco Bay and the broader region.
While erosion-resistant granite juts from the sandy shorelines in southern Maine to form rocky headlands, metamorphic bedrock becomes the dominant surface feature east of Portland. There, whole ridges and valleys made of rock layers transformed by exposure to high pressures and temperatures define the landscape. During the last ice age, glaciers scoured and widened many of these coastal valleys, which later flooded as the Laurentide Ice Sheet melted and sea levels rose.
Around Casco Bay, these ridge-and-valley systems, combined with the drowning of the shoreline, produce the jagged, highly indented shoreline and many long, narrow islands seen today. “The tortured folds of these old landscapes also set up a sharp directional preference for erosion to exploit,” said Nicholas Whiteman, also a geologist with the Maine Geological Survey. “This led to the eye-catching difference in the orientation of the islands and necks that dominate Casco Bay compared with those to the northeast.”
The various forms that coastlines take fascinate geologists, but they also carry everyday implications for the economies of Maine’s coastal communities. While tourists flock to the sandy beaches of communities like Saco and Kennebunkport, the state’s iconic lobster fisheries are concentrated in Midcoast Maine. The crustaceans thrive in the cold waters of the region’s many rocky, protected inlets, turning communities such as Harpswell into leaders in lobster landings.
The state’s oyster farms are also concentrated in this region. Casco Bay and the Damariscotta Estuary, sheltered from winds and waves, offer waters that farmers can easily access without large boats. These waters provide a range of temperatures, salinities, and other characteristics that create numerous microclimates where oysters can grow quickly and take on a variety of tastes, known as merroir, explained Tom Kiffney, a researcher at the University of Maine. Kiffney is part of a team of researchers using Landsat and other satellite observations to predict oyster growth rates and help identify the most promising locations for new oyster farms in Maine based on water temperatures and quality.

This will be the second flight to the space station for Watkins, who was selected as a NASA astronaut in 2017. Watkins grew up in Lafayette, Colorado, and earned an undergraduate degree in geological and environmental sciences from Stanford University, as well as a doctorate in geology from the University of California, Los Angeles. As a geologist, she studied the Martian surface and was a member of the Curiosity rover science team at NASA’s Jet Propulsion Laboratory in Southern California. Watkins first launched to the space station as a crew member aboard NASA’s SpaceX Crew-4 mission, spending a total of 170 days in space across space station Expeditions 67/68 in 2022. She will be the first NASA astronaut to launch aboard a SpaceX Dragon spacecraft twice.
Selected as a NASA astronaut in 2021, Delaney earned a bachelor’s degree in mechanical engineering at the University of North Florida and a master’s degree in aerospace engineering at the Naval Postgraduate School. The Florida native is a distinguished naval aviator who participated in exercises throughout the Asia Pacific region and conducted missions in support of Operation Enduring Freedom. As a test pilot, Delaney evaluated developmental aircraft systems and served as a test pilot instructor. He also worked as a research pilot at NASA’s Langley Research Center in Hampton, Virginia, where he supported airborne science missions. This is the first spaceflight for Delaney.
The Crew-13 mission also is the first spaceflight for Kutryk. Prior to his selection as a CSA astronaut in 2017, he served as a CF-18 fighter pilot, flying missions in support of Canada’s NATO, U.N., and North American Aerospace Defense Command commitments. A native of Fort Saskatchewan, Alberta, Kutryk also worked as an experimental and operational test pilot at the Aerospace Engineering Test Establishment in Cold Lake, Alberta. Kutryk received a bachelor’s degree in mechanical engineering from the Royal Military College of Canada in Kingston, Ontario, and he is a distinguished graduate of the United States Air Force Test Pilot school in Edwards, California. He has master’s degrees in space studies, flight test engineering, and defense studies.
This mission will be Teteryatnikov’s first trip to the orbiting laboratory. He graduated from the Naval Academy, St. Petersburg, Russia, in 2011 as an engineer specializing in ship power plant operations. Before his selection as a test cosmonaut, Teteryatnikov served in various naval engineering roles, including undersea vessels and specialized engine room operations. He was selected for the Gagarin Research and Test Cosmonaut Training Center Cosmonaut Corps in 2021 and has served as a test cosmonaut since 2023.
New NASA Earth Missions Gear Up to Start Science Flights

Landslides in Alaska. Air quality in Atlanta. Fire clouds out West. From the Arctic fringes to farm country, NASA’s newest class of suborbital Earth Venture missions is gearing up to deliver science that will benefit communities in the United States and beyond.
The six projects will mobilize hundreds of scientists and pilots from NASA, the U.S. Navy, universities, and other institutions over the next several years. While the investigations range across topics, a defining feature of suborbital missions is the use of sensors mounted on aircraft.
Airborne remote sensing serves as a bridge between ground-based instruments and satellites. Data collected via planes, helicopters, drones, and balloons can fill in gaps in computer models used by weather forecasters, city planners, and others.
When wildfires create their own weather
The first project to take wing this summer is Injected Smoke and PYRocumulonimbus Experiment (INSPYRE), led by the Naval Research Laboratory. From mission headquarters in Colorado, the team will chase one of the least understood forms of severe weather on Earth: towering “fire clouds” generated when extreme wildfires burn hot enough to brew their own thunderstorms.

Smoky and crackling with lightning, these unique storms can create blind spots for aviators above and spark new blazes below. Measuring and mapping the dangerous storms as they develop in real-time will help scientists forecast them in the future. Several aircraft, including NASA’s high-altitude ER-2, flying out of Montana, will carry a large suite of instruments over wildfire-generated storm systems. Among them will be two state-of-the-art infrared wildfire trackers, which were developed at NASA’s Jet Propulsion Laboratory (JPL) in Southern California and will be flying as part of the agency’s FireSense program.
Testing the air over farmland, megacities
Agricultural emissions represent an important and understudied part of Earth’s land and atmosphere systems. The FarmFlux mission, which kicks off this year, will deploy more than a dozen sensors to measure ozone, methane, ammonia, particulates, and other pollutants rising from agricultural lands and animal farms stretching from the Midwest to California’s Central Valley. These emissions affect human health, global climate, and stratospheric ozone. The mission is led by NASA’s Goddard Space Flight Center in Greenbelt, Maryland, along with Colorado State University, and Boston University.
NASA’s 777 aircraft is gearing up to start science flights. Structural modifications – like enlarged cabin windows and instrument portals – have transformed the former passenger plane into a flying laboratory. It’s seen here at Langley Research Center in Hampton, Virginia, in April 2026.

Two North American cities with air quality concerns are Atlanta and Mexico City. But the causes differ, with weather and terrain playing a role. To explore these differences, the Hemispheric Airborne Measurements of Air Quality (HAMAQ) mission will investigate areas of poor air in the two capitals and test how satellite information can help forecasting and mitigation efforts. The team will deploy two aircraft at different altitudes: NASA’s P-3B will fly close to the surface, directly measuring fine particle and gaseous pollutants, while the recently acquired 777 science jet will soar high above, mapping pollution with remote sensors. NASA’s Langley Research Center in Hampton, Virginia, is leading the mission.
Fast-changing north
As the Arctic warms at least twice as fast as the rest of Earth, data collected today can help guide communities on the front lines of change.
Alaska’s glaciers are losing ice and contributing to sea level rise. NASA is tracking the changes from land, air, and space.
NASA
The Snow4Flow campaign, led by the University of Arizona, seeks to measure and model how far and fast glaciers are retreating in the far north. Traversing remote icescapes across Alaska, the Yukon, Arctic Canada, Greenland, and Svalbard, Norway, they’ll sound both the near-surface and frozen depths of hundreds of glaciers while flying over in a modernized WWII-era aircraft outfitted with a scanning laser altimeter and two custom radars. Their observations, combined with satellite data and advanced models of snowfall and glacier flow, will advance our understanding of how glaciers behave in different regions of the Arctic. The mission seeks to uncover not just what these glaciers look like beneath the surface today, but the processes that will drive changes in the future.
As permafrost thaws, rivers on the doorstep of the Arctic become conveyor belts of carbon and sediment. NASA Goddard, and the City College of New York lead a multidisciplinary team studying how rivers, lagoons, and estuaries across Alaska’s North Slope interact with the Arctic Ocean. The project, called Frontlines of Rapidly Transforming Ecosystems (FORTE) will combine optical and radar measurements from satellites, planes, high-tech research vessels, drones, and underwater autonomous systems to track microscopic marine life, water flow, and chemistry. The team will collaborate with local and tribal communities to sustain observations over time and apply NASA assets to address emerging local needs and decision-making priorities.
Landslide triggers
When a slow-moving landslide in California suddenly collapsed and buried a section of coastal highway in 2017, scientists at NASA JPL wanted to know how precipitation swings played a role. JPL studies how water infiltrates and destabilizes hillslopes all over the world. The Landslide Change Characterization Experiment (LACCE) project will combine airborne synthetic aperture radar with land-based sensors to track how slopes in California are responding to a world of intensifying droughts and downpours. The project also takes aim at emerging landslide hazards in Alaska, where rapidly retreating glaciers are accelerating slope movements that have the potential to create mega-tsunamis.
This series of images shows the collapse of the Mud Creek landslide in May 2017 along the Big Sur coast in Central California, and the subsequent repairs to Highway 1, which was damaged during the event.

NASA’s Earth Venture Suborbital program, designed to be nimble and high impact, was established following a recommendation by the National Research Council in 2007. In the decades since, teams have studied phenomena, including blizzards, coral reefs, and ocean whirlpools.
On the morning of July 20, 1976, roughly 40 minutes after mission controllers received word that the Viking 1 lander had successfully touched down on the surface of Mars, this photo gave us our first view from the surface of another planet.
NASA/JPL
“Touchdown, we have touchdown!” At 5:12 a.m. PDT, July 20, 1976, mission controllers at NASA’s Jet Propulsion Laboratory erupted in cheers as they learned that the Viking 1 lander had survived its descent through the thin Martian atmosphere. Forty minutes later, the lander’s first image began to appear on their monitors, slowly forming line by line from left to right. For the first time, humans were able to see Mars’s rocky terrain from its surface.
Dr. Thomas Mutch, leader of the Viking lander imaging team, described the moment: “I studied the black screen, waiting for that narrow strip that will signal the first few lines of the first picture. And it appeared. A sliver of electronic magic. Areas of brightness and darkness. The picture begins to fill the screen. Rocks and sand are visible and — finally at the far right — one of the spacecraft foot pads, a symbolic artifact that stamps our accomplishment with the sign of reality. Time and time again I repeat, ‘It’s incredible.’”
Fifty years ago today, the Viking 1 lander became NASA’s first robot to explore Mars’s surface and begin the search for signs of life in our solar system. Viking 1 was joined six weeks later by its twin lander, Viking 2, which explored a different region of Mars, while two mission orbiters that delivered the landers to the Red Planet continued to collect data from space and helped relay communications to Earth.

Seattle, Washington—sometimes known as the “Emerald City”—was glimmering in the morning sunlight when an astronaut aboard the International Space Station took this photo on June 16, 2026. The city’s parks and tree-filled neighborhoods lend a lush, green look to the metropolis, while tall buildings downtown cast long shadows and ships navigate surrounding waterways.
The broad contours of the city’s landscape and the water around it owe their shape to the advance and retreat of glaciers during the last ice age. Between roughly 18,000 and 16,000 years ago, the Puget lobe of the Cordilleran ice sheet covered the area in a mass of ice up to 3,300 feet (1,000 meters) thick. The glacier scoured the basins now occupied by Puget Sound and the region’s lakes.
The glacier left its mark above water, too. Several of Seattle’s notorious hills (of which there are seven or more, depending on who’s counting) are drumlins. These elongated mounds of glacial debris run north-south, parallel to the direction of the ice’s movement. East-west travelers in the city, facing challenging ups and downs, may attest to this topographic trend.
The ice also transported large boulders called glacial erratics from more northerly locations and deposited them around the region. A particularly large erratic, the Wedgwood Rock, stands about 20 feet (6 meters) tall and draws its name from the North Seattle neighborhood in which it rests.
June 16, 2026
In more recent times, humans have undertaken projects to rework the topography. Notable alterations include leveling Denny Hill north of downtown and filling in tideflats at the mouth of the Duwamish River south of downtown, which created around 1,300 acres of new land. Seattle’s professional sports stadiums sit atop this fill.
This photo was acquired after several development projects to update waterfront infrastructure downtown, initiated in 2010, were completed. These include a new ferry dock and terminal, a rebuilt seawall, and a tunnel to replace an above-ground highway and create more inviting public access to the waterfront.
Some replumbing of the region’s waterways is apparent from the astronaut’s perspective, as well. In the 1910s, the Army Corps of Engineers built canals on either side of Lake Union to connect Puget Sound (an inlet of the Pacific Ocean) with Lake Washington. Starting in 1916, the Montlake Cut connected Lake Washington to Lake Union, and the Ballard Locks, northwest of Lake Union, began raising and lowering watercraft between the freshwater lakes and tidal Puget Sound. As a result of this project, Lake Washington’s water level dropped about 9 feet (3 meters) and ceased draining from its natural outlet at its southern end.
Today, the waters in and around Seattle support many uses: container ships, cruise ships, car and passenger ferries, floatplanes, and recreational craft ply the sound and lakes. And as for Seattle’s emerald nickname, pockets of old-growth forest still exist within city limits, containing centuries-old trees such as Douglas fir, Western red cedar, and Western hemlock. Seattleites often spot wildlife such as bald eagles, coyotes, and sea lions in the city’s various habitats.
Astronaut photograph ISS074-E-723719 was acquired on June 16, 2026, with a Nikon Z9 digital camera using a focal length of 560 millimeters. It is provided by the ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing Unit at NASA Johnson Space Center. The image was taken by a member of the Expedition 74 crew. The image has been cropped and enhanced to improve contrast, and lens artifacts have been removed. The International Space Station Program supports the laboratory as part of the ISS National Lab to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet. Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of Earth. Story by Lindsey Doermann.
