  Icebreakers play a critical role in delivering supplies to America's largest research base in Antarctica. The post Cracking Antarctic Sea Ice appeared first on NASA Science.
• Seasons Change in Southwest Virginia (2026/02/02 05:00)

  From autumn color to a winter-white finish, forested areas around Blacksburg trade foliage for snow over the span of two months. The post Seasons Change in Southwest Virginia appeared first on NASA Science.
• Visualizing Perseverance’s AI-Planned Drive on Mars (2026/01/30 20:30)

  Description This animation of NASA’s Perseverance was created with the Caspian visualization tool using data acquired during an 807-foot (246-meter) drive on the rim of Jezero Crater made by the rover on Dec. 10, 2025, the 1,709th Martian day, or sol, of the mission. The mission’s “drivers,” or rover planners, use the information to understand the Perseverance’s […] The post Visualizing Perseverance’s AI-Planned Drive on Mars appeared first on NASA Science.
• Video: Perseverance Rover’s View of Crater Rim Drive (2026/01/30 20:02)

  Description This animation shows Perseverance’s point of view during drive of 807 feet (246 meters) along the rim of Jezero Crater on Dec. 10, 2025, the 1,709th Martian day, or sol, of the mission. Captured over two hours and 35 minutes, 53 Navigation Camera (Navcam) image pairs were combined with rover data on orientation, wheel speed, […] The post Video: Perseverance Rover’s View of Crater Rim Drive appeared first on NASA Science.
• Mapping Perseverance’s Route With AI (2026/01/30 19:31)

  Description This annotated image from NASA’s HiRISE (High Resolution Imaging Science Experiment) camera aboard the agency’s Mars Reconnaissance Orbiter image depicts the AI-planned route and the actual route taken by NASA’s Perseverance Mars rover during its 807-foot (246-meter) drive on Dec. 10, 2025, the 1,709th Martian day, or sol, of the mission. The drive was the second of two demonstrations […] The post Mapping Perseverance’s Route With AI appeared first on NASA Science.
• U.S.-India NISAR Satellite Images Mississippi River Delta Region (2026/01/30 16:41)

  Description The NISAR (NASA-ISRO Synthetic Aperture Radar) Earth-observing satellite’s L-band synthetic aperture radar (SAR) instrument captured this image of the Mississippi River Delta region in southeastern Louisiana on Nov. 29, 2025. The colors in the image represent varying types of cover, which tend to reflect microwaves from the radar differently. Portions of New Orleans appear […] The post U.S.-India NISAR Satellite Images Mississippi River Delta Region appeared first on NASA Science.
• Extreme January Cold (2026/01/30 05:00)

  Following a significant winter storm, frigid temperatures lingered in late January 2026 across a vast swath of the U.S. The post Extreme January Cold appeared first on NASA Science.
• Ammonia-Bearing Compounds Discovered at Surface of Jupiter’s Moon Europa (2026/01/29 22:25)

  Description Advanced analysis of decades-old data from NASA’s Galileo spacecraft identifies ammonia-bearing compounds discovered on the surface of Jupiter’s moon Europa, as shown in this composite image. Zooming in on an area about 250 miles (about 400 kilometers) wide, the black-and-white mosaic to the right is composed of multiple images from Galileo’s Solid-State Imaging camera.
