A Sea of Spinning Clouds

2026-05-07 04:01

Parallel lines of cloud vortices appear downwind of a small, ice-covered island.

Over the Southern Ocean surrounding Antarctica, winds can whip around the globe relatively unimpeded by land. Intrepid sailors termed these southern latitudes the Roaring Forties, Furious Fifties, and Screaming Sixties on account of the strong prevailing winds.

When those winds encounter a barrier like an island, the disruption in airflow can be beautiful. One impediment, shown here, is remote Peter I Island. This ice-cloaked volcano lies at 68.86 degrees south latitude in the Bellingshausen Sea, some 400 kilometers (250 miles) off the coast of West Antarctica and more than 1,800 kilometers (1,100 miles) from Cape Horn, Chile.

On an austral summer day in 2026, the Landsat 8 satellite captured this image of von Kármán vortex streets downwind of the island. These counterrotating spirals form as flowing air is deflected, slows, and spins into eddies. A stiff, but perhaps not quite “screaming,” wind was likely blowing that day. Wind speeds typically need to be 18 to 54 kilometers (11 to 34 miles) per hour for vortices to form. With stronger gales, the eddies cannot maintain their shape. The following day, vortex streets appeared within a complex array of cloud types near the island.

Where the clouds parted around the island, some of its icy edifice became visible to the satellite. A 100-meter-wide circular crater sits at its summit, 1,640 meters (5,380 feet) above sea level. The Smithsonian Institution’s Global Volcanism Program describes the island as a “shield-like volcano,” but there are no records of recent eruptions.

Scientific research on Peter I Island has been limited due to its remote location and the challenging ice conditions surrounding it. The island was discovered in 1821 by the Russian explorer Fabian Gottlieb von Bellingshausen and named for a tsar, but no one landed on it until 1929. The relatively few studies since have focused on geology, biodiversity, and the climate history recorded in its ice.

NASA surveyed the island during an Operation IceBridge campaign in 2011. This airborne science mission collected a suite of measurements over Earth’s polar ice in the period between the ICESat and ICESat-2 satellite missions to sustain the record of observations in these regions. While NASA’s DC-8 aircraft flew back to Chile from Antarctica, where teams spent the day measuring the Getz Ice Shelf and Thwaites Glacier from the air, the crew on board caught a rare glimpse (above) of the remote island.

NASA advances aeronautics and space technologies through experimental aircraft and flight research at the agency’s Armstrong Flight Research Center in Edwards, California. Behind those efforts is the Dryden Aeronautical Test Range (DATR), which provides the communications, tracking, and data services that enable safe and effective missions.

For most NASA Armstrong research flights, the DATR supplies communications, radar, and telemetry. The range’s video capabilities can also capture ground footage as well as long-range coverage for flights. Modernization efforts started in the early 2020s expanded those capabilities and prepared the range to support efforts such as test flights of NASA’s X‑59 quiet supersonic research aircraft, as well as spaceflight communications.

“The DATR provides real‑time data, tracking, and situational awareness that help keep flight research safe and efficient,” said Tara McCoy, acting deputy director for DATR Mission Operations at NASA Armstrong. “The range also supports science missions, works with industry partners, and provides capabilities used for International Space Station operations.”

Ongoing upgrades include new very high frequency (VHF) ground antennas, updated electronic components, and software improvements for tracking the International Space Station and visiting spacecraft. NASA installed additional antennas to ensure backup coverage.

The range’s ability to processes and display real‑time radar, telemetry, and video data is critical for monitoring research flights, such as NASA’s Crossflow Attenuated Natural Laminar Flow (CATNLF) wing model. CATNLF, a scale-model wing attached under a NASA F-15B research jet, is designed to improve the smooth flow of air known as laminar flow, reducing drag and lowering fuel costs for future commercial aircraft.

The DATR also supports aircraft platforms that enable science missions, such as the ER-2 high-altitude aircraft and the C-20A aircraft.

One large central screen, surrounded by four smaller screens on each side, spans the front wall of a control room displaying video and research flight data. Rows of engineers wearing headsets monitor real-time data on their computer screens.
NASA’s X-59 quiet supersonic research aircraft first flight travels from Lockheed Martin’s Skunk Works facility in Palmdale, California, to NASA’s Armstrong Flight Research Center in Edwards, California, on Tuesday, Oct. 28, 2025. The control room at NASA Armstrong enabled engineers to monitor real-time flight data, maintain communication, and view video throughout the mission, demonstrating the capabilities of the center’s Dryden Aeronautical Test Range.

Preparing for future flights

The range is developing multiple approaches to streamline and shorten the time it takes to process and validate raw flight data for researchers, saving time and resources.

“The faster we can get data to the project engineers to review, the faster they can determine whether certain test points need to be repeated, or future test points can be skipped,” said David Tow, DATR chief engineer. “We are working these efforts simultaneously because each one has the potential to drastically improve how long it takes to deliver post-processing data.”

One NASA approach is to automate and consolidate the data processing steps from five down to one. Another approach leverages an existing partnership with the U.S. Air Force to enable multiple computers to post-process data from separate missions simultaneously. The collaboration between the Air Force and DATR aims to reduce processing time for post-flight data from two hours to less than 30 minutes.

Supporting space station operations

The DATR is part of NASA’s safety and communications infrastructure that supports International Space Station missions. Its capabilities are used for backup communications and telemetry during launches, dockings, and reentries.

NASA Armstrong is one of only two ground stations in the United States capable of sending and receiving messages on all space station frequencies. The other is NASA’s Wallops Flight Facility in Virginia. Armstrong has provided communications and radar tracking for the station since its first component launched in 1998 and continues to support commercial cargo and crew missions.
