During the Aug. 12 total solar eclipse over Europe, scientists aimed to study a long-standing mystery: why the Sun’s outer atmosphere, the corona, is far hotter than its visible surface. Capturing the data they needed meant being in exactly the right place at the right time. 

Pilots from NASA’s Johnson Space Center flew the WB-57F high altitude research aircraft from Ellington Field in Houston to Iceland, their base for flying through the path of totality to give scientists a clearer view of the Sun’s corona. 

A total solar eclipse provides a unique opportunity to examine the corona because the Moon temporarily blocks the Sun’s bright surface, revealing its fainter outer atmosphere. Observations collected during this brief window can help scientists better understand how energy and material move through the corona and away from the Sun, improving our understanding of space weather. 

At about 50,000 feet, the WB-57F flew above most clouds, dust, and water vapor that can interfere with observations from the ground. The altitude reduced atmospheric interference while also allowing the science instruments to observe infrared wavelengths that are largely absorbed lower in Earth’s atmosphere. 

Capturing those observations required careful coordination between scientists and the flight crew. Before the mission, teams calculated where the aircraft needed to be as the Moon’s shadow moved across the North Atlantic.  

“Going into a mission like this takes a huge team. It starts with the science team establishing the requirements, and then we work closely with them for months leading up to the mission,” said Tom Parent, NASA WB-57F pilot. “We rely heavily on our maintenance team to get the instruments serviced, prepared, loaded onto the aircraft, and flight tested. It’s a huge team effort to get an aircraft like this up there to image and achieve these objectives.” 

During totality, NASA WB-57F pilot John Gustine positioned the aircraft along the eclipse path to maximize time in the Moon’s shadow and give scientists as much opportunity as possible to collect data. 

From the back seat, Cary Klemm, sensor equipment operator for NASA’s WB-57F, controlled the camera systems, adjusting focus and exposure times while tracking features of interest throughout totality. 

With the cameras capturing observations throughout the brief window, every second mattered. 

“Every image is another piece of data that could reveal something new about the Sun,” Klemm said. 

What scientists can learn from those observations reaches far beyond the eclipse itself. The Sun’s corona is made of plasma shaped by magnetic fields, and many of the same physical processes occur elsewhere in the universe. 

“The NASA WB-57F’s unique capabilities of high-altitude flight were truly crucial in providing access to these valuable wavelengths during an eclipse whose path crossed mostly over the ocean in an area where clouds are common,” said Amir Caspi, principal investigator for the study at Southwest Research Institute in Boulder, Colorado. “We could not have achieved this success without this platform, and all of the efforts of the many intrepid ground, air, and science crew members.”

The data gathered during the flight will give scientists another opportunity to investigate the Sun and the processes that influence the space environment around Earth.

NASA astronaut Mike Fincke is departing the agency on Wednesday after 30 years of service. Throughout his career, he flew four missions, spent 549 days in space, and completed nine spacewalks in support of the International Space Station.

“Few people have had the opportunity to shape as many chapters of NASA’s history as Mike Fincke,” said NASA Administrator Jared Isaacman. “Over a remarkable career, Mike served our nation as a pilot, engineer, astronaut, and mentor. From long-duration missions aboard the International Space Station to helping prepare the Artemis generation, his contributions have helped position NASA for what comes next. The success we’re building on today is possible because of people like Mike, who dedicated their careers to moving our space program forward and preparing the next generation to carry the mission even further. I’d like to congratulate Mike on an incredible career and thank him for his decades of service to NASA, our nation, and the countless people who had the opportunity to learn from and fly alongside him.”

He ranks fourth among NASA astronauts in accumulated time in space, and his spacewalks total 48 hours and 37 minutes. Most recently, Fincke piloted NASA’s SpaceX Crew‑11 mission, which launched in August 2025 and returned in January. During the mission, he served as a flight engineer for International Space Station Expedition 73 and commander of Expedition 74.

Fincke joined NASA’s 16th astronaut class in 1996 and first flew to space in 2004 aboard Soyuz TMA‑4 in support of the space station’s Expedition 9. Serving as a science officer and flight engineer, he helped maintain station systems and performed four spacewalks. He returned to space in 2008 on Soyuz TMA‑13 as commander of Expedition 18, preparing the space station for its transition to six‑person crews at the time and completing two more spacewalks.

In 2011, Fincke flew on STS‑134, the final flight of space shuttle Endeavour. As mission specialist and robotic arm operator, he completed three spacewalks and helped deliver and install the Alpha Magnetic Spectrometer.

“Mike’s remarkable career reflects three decades of dedication to NASA’s mission and the advancement of human spaceflight,” said Vanessa Wyche, director of NASA’s Johnson Space Center in Houston. “From his time aboard the International Space Station to his commitment to mentoring the next generation, Mike has made an immense impact across our agency. His legacy of service, mentorship, and dedication to exploration will continue to inspire the generations to come.”

Throughout his career, Fincke bridged spacecraft development, flight testing, and mission operations. Early in the International Space Station Program, he helped test and integrate several of the station’s initial modules before launch. His flight experience spanned multiple generations of human spacecraft, including two missions aboard Soyuz, one aboard the space shuttle, and later piloting the SpaceX Dragon.

Fincke was a foundational contributor to NASA’s Commercial Crew Program. As chief of the Astronaut Office’s Commercial Crew Branch, he worked to ensure astronaut needs, crew safety, and human spaceflight experience informed development of the nation’s next generation of crewed spacecraft. He spent five years supporting Boeing’s Crew Flight Test program training as a crew member and backup pilot, contributing to flight software, systems integration, integrated testing, and spacecraft interfaces.

Fincke also supported station operations from the ground as a crew test support team member in Russia, a capsule communicator, or capcom, and crew procedures team lead. He helped translate complex engineering and operational requirements into clear instructions for crews working in orbit. His continuity across development, integration, mission support, and long‑duration flight gave him an end‑to‑end perspective on space station assembly and operation.

“Mike approached every assignment with experience, humility, and an unwavering focus on the mission,” said Scott Tingle, chief of the Astronaut Office at NASA Johnson. “Whether flying aboard the station, supporting crews from the ground, or helping shape the spacecraft that future crews will rely on, he consistently strengthened our team. His legacy is woven into the way we fly today.”

A native of Emsworth, Pennsylvania, Fincke holds bachelor’s degrees in aeronautics and astronautics and in Earth, atmospheric, and planetary sciences from the Massachusetts Institute of Technology, where he also studied in the Soviet Union through an exchange program with the Moscow Aviation Institute. He earned master’s degrees in aeronautics and astronautics from Stanford University and in planetary geology from the University of Houston, Clear Lake.

Fincke is a retired U.S. Air Force colonel and distinguished graduate of the U.S. Air Force Test Pilot School. He served as a space systems engineer and flight test engineer at Edwards and Eglin Air Force Bases and later as the U.S. flight test liaison to the Japanese‑U.S. XF‑2 fighter program at Gifu Air Base in Japan. He accumulated more than 2,000 flight hours in more than 30 aircraft types.

“After exactly 30 years, I am departing NASA, but I remain deeply committed to the work of exploration.” Fincke said. “NASA gave me the extraordinary privilege of serving alongside remarkable people, flying and helping develop spacecraft, and contributing to the International Space Station from its earliest days through command in orbit. I am profoundly grateful to my crewmates, the teams on the ground, our international partners, and the families who make this work possible. I am excited to carry those lessons forward and help prepare the next generation of engineers, explorers, and leaders. Together, we will return humanity to the Moon, travel to Mars, journey outward to the planets and moons beyond Earth, and someday reach for the stars – all while caring for Earth, the most beautiful planet in our solar system.”

Between Aug. 11 and 12, NASA’s Lunar Reconnaissance Orbiter (LRO) captured a series of images of a new crater on the Moon. The crater formed on Aug. 5, when a SpaceX Falcon 9 upper stage impacted the surface following its January 2025 launch of the Firefly Blue Ghost 1 mission.

To capture imagery of the impact, engineers tilted the spacecraft so its cameras would point toward the crater each time LRO passed about 60 miles above the Moon, traveling 1 mile per second. The orbiter circles the Moon from pole to pole every two hours, while the Moon slowly rotates underneath it. To photograph a specific spot, the spacecraft must wait until that location turns into view, which took six days in this case.

Getting the pointing right was only half the challenge; timing had to be accurate as well. If the camera snapped even 10 seconds too early or too late, the target would drift off-center by 10 miles.

Because of the variety of viewing angles, scientists could see the crater under multiple lighting conditions that revealed unique features. In images where the crater rim stood out, scientists measured its 60‑foot width. Scientists also determined the crater is less than 10 feet deep based on the length of its shadow.

To capture these details, LRO used its Narrow-Angle Camera, which can spot features as small as 3 feet wide.

The images above show bright and dark rays stretching out from the crater. The darker streaks are made of surface dust and rocks altered over a long time by solar wind, galactic cosmic rays, and micrometeorite impacts. This weathered material was excavated by the collision from 1.5 feet into the lunar surface. The brighter streaks near the crater rim are made of fresh material excavated from deeper underground.

Finding the impact site took global coordination among experts and hobbyists. Independent astronomers first identified the rocket’s trajectory using publicly available data. NASA’s Center for Near Earth Object Studies, which tracks natural objects that could pose hazards to Earth for the agency’s Planetary Defense program, used this opportunity to test and validate tools and techniques for predicting impacts.

Based at NASA’s Jet Propulsion Laboratory in Southern California, the center incrementally refined the trajectory until identifying the location of impact, which it provided to the Republic of Korea for their Korea Pathfinder Lunar Orbiter (Danuri) team. The team used the high-resolution LUTI camera on Danuri a few hours later to image the crater, finding the prediction was accurate to about 0.6 miles. 

After capturing images of the crater, the Danuri mission sent coordinates to NASA’s LRO team to help refine their follow-up imaging sequence. Comparing their new crater images with the pre-impact images, the LRO team updated the crater center coordinates: 19.4759°N, 266.7138°E, 511 meters elevation.
