• NASA’s SPHEREx Examines Comet 3I/ATLAS’s Coma (2026/02/04 16:18)

  Description These observations by NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) show the infrared light emitted by the dust, water, organic molecules, and carbon dioxide contained within comet 3I/ATLAS’s coma. The comet brightened significantly during the December 2025 period when SPHEREx made the observations — about two […] The post NASA’s SPHEREx Examines Comet 3I/ATLAS’s Coma 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.
