Image Sequences

November 11th, 2024 - France at Night

This sequence of nine images, taken late at night on November 11th in Europe, begins over the coast of Belgium and the Netherlands. The images proceed in a south-westerly direction, cutting across the length of France and reaching to the Pyrenees in the final image. Numerous cities and urbanized areas shine against the deep black of night. The brightest of these, seen in the first half of the sequence, is Paris. Other cities seen in the sequence include Orléans, Le Mans, Tours, Bordeaux, and Toulouse. This image was taken with the narrow-angle camera on the spacecraft. North is roughly to the top right of the image.

October 16th, 2024 - Tucson

This sequence of five images, taken on the morning of October 16th, begins high over Tucson. During this sequence, the spacecraft used its attitude control suite to track Tucson as it flew overhead, attempting to keep the city in center frame. In the first image, Tucson is visible as a gray spot on near the center of the image, just below a spur on the cloud front. As the perspective changes, a larger track of the Earth is visible, out to the limb in the final image. Although the images are not perfectly centered, this was a successful demonstration of CatSat's ability to point to and track a desired target. This image was taken with the narrow-angle camera on the spacecraft. North is to the left of the image.

September 22nd, 2024 - Argentina and Chile across the Andes

This sequence of ten images, taken on the morning of September 22nd, begins over the Patagonian steppe in Southern Argentina. The dry desert air gives the terrain a brown coloration on which dark water features are easy to spot. The two most notable features are the Embalse Alicura (Alicura Reservoir) and the Embalse Ezequiel Ramos Mexia (Ezequiel Ramos Mexia Reservoir), both on the Limay River. As the spacecraft continues on its north-westerly path, the rugged, snow-capped Andes mountain range marks the border between Argentina and Chile. On the Chilean side, the highly vegetated Valdivian rainforest is dark and has poor contrast with the Pacific Ocean, but wind swept clouds mark the Chilean coastal range. The high mountain peaks cause the humid ocean wind to drop its moisture on the western side of the Andes, leaving it dry when it reaches the eastern side. This causes the stark contrast between the Valdivian rainforest in Chile and the Patagonian desert in Argentina. In the latter half of the sequence, a large sheet of clouds covers the Chilean central valley as the image sequence ends over the Pacific Ocean. These images were taken with the narrow-angle metrology camera on the spacecraft. North is roughly towards the top left of the images.

September 11th, 2024 - Pacific Ocean off the Coast of Mexico

This sequence of five images, taken on the morning of September 11th, begins over the Pacific Ocean south of Baja California. The images start over a stormy, cloud-covered area before moving North towards clearer waters. In the final image, the very tip of Baja California Sur appears on the left. This sequence was captured to test a new imaging script while the spacecraft was in communication with controllers in Tucson, more than 600 miles away.  These images were taken with the narrow-angle metrology camera on the spacecraft. North is roughly towards the bottom left of the images.

September 9th, 2024 - Central Texas during Daytime

This sequence of five images, taken on the morning of September 9th, begins over central Texas in late morning. Austin and San Antonio are faintly visible between the green ridge and the cloud front in the first image. The images proceed North, roughly towards the bottom left of the image, capturing images of Oklahoma and parts of Kansas and Colorado. These images were taken with the wide-angle metrology camera on the spacecraft. The dark areas at the top left and bottom left corners are parts of the structure of the spacecraft not illuminated by the Sun.

August 28th, 2024 - Clouds over Arctic Ice

This sequence of five images, taken on the morning of August 28th, begins over the Arctic Ocean. In the gaps between thick, puffy clouds, bright white sheets of ice can be seen floating on dark water. As the spacecraft moves into sunlight, the images become more washed out. This sequence was taken as a test of CatSat's scheduling and pointing capability. As the spacecraft began rotating during the sequence, the final two images show the Earth at a different angle. However, the lack of detail in the image makes this difficult to notice. These images were taken with the narrow-angle metrology camera on the spacecraft.

August 18th, 2024 - Central Texas at Night

This sequence of five images, taken on the night of August 18th, begins over central Texas at night. In the first image, the night-time illumination of the Dallas-Fort Worth, Houston, Austin, and San Antonio metropolitan areas are brightly visible. Due to the darkness of night, almost no details are seen of the Earth's surface. In the top left of the image, the glow of the atmosphere illuminated by the Sun beyond the horizon shines brightly. These images were taken with the wide-angle metrology camera on the spacecraft. North is roughly towards the top right of the image.

August 10th, 2024 - Nevada to Central Oregon

This sequence of five images, taken on the morning of August 10th, begins centered on Nevada. The California Central Valley is visible to the bottom right and Lake Tahoe is near the bottom center of the first image. As the spacecraft moves north-ward in its orbit, the following images move into Oregon, where large wildfires have filled the atmosphere with smoke. These images were taken with the narrow-angle metrology camera on the spacecraft. North is roughly towards the left of the images.

August 4th, 2024 - Baja California to Southwestern US

This sequence of five images, taken on the morning of August 4th, begins over the western coast of Baja California. As the spacecraft moves north-ward in its orbit, the following images show the Sea of Cortez and parts of Southern California, Arizona, and Sonora. These images were taken with the narrow-angle metrology camera on the spacecraft. North is roughly towards the bottom left of the images.
