Sunshade for NASA’s NEO Surveyor Mission Ready for Its Day in Sun

https://science.nasa.gov/blogs/neo-surveyor/2026/10/26/sunshade-for-nasas-neo-surveyor-mission-ready-for-its-day-in-sun/ Development of NASA’s Near-Earth Object (NEO) Surveyor mission continues as the spacecraft’s largest component gets closer to how it will look when it launches. Recently, teams completed work on integrating solar arrays onto the spacecraft’s sunshade, a structure primarily designed to block the Sun’s glare. The sunshade will keep the infrared space telescope cool as it searches for near-Earth asteroids and comets while also providing the spacecraft with power.

NASA’s Perseverance Offers Clues to Protect Crews From Mars Dust

https://www.nasa.gov/missions/mars-2020-perseverance/nasas-perseverance-offers-clues-to-protect-crews-from-mars-dust/ Over 1,645 Martian days, NASA’s Perseverance Mars rover measured the fine and ultrafine Martian dust particles found clinging to samples of spacesuit materials that are carried aboard the rover, including some that are small enough to penetrate the lungs and enter the bloodstream. The findings will be published Tuesday, Oct. 27, in the Proceedings of the National Academy of Sciences and could inform spacesuit and habitat design, dust-removal procedures, and crew health standards for future NASA missions to Mars.

NASA’s Hubble Charts Path for Roman with Gravitational Lenses

https://science.nasa.gov/missions/hubble/nasas-hubble-charts-path-for-roman-with-gravitational-lenses/ A sweeping barred spiral galaxy marks the spot in this image, but the real treasure is the gravitational lens in the lower-right corner, where a distant background galaxy is being magnified and distorted by the gravity of a closer galaxy. This observation is one of many gravitational lensing images taken by NASA’s Hubble Space Telescope in preparation for science with the new Nancy Grace Roman Space Telescope.

NASA’s Roman Space Telescope Enters Final Commissioning Phase

https://science.nasa.gov/blogs/roman/2026/10/22/nasas-roman-space-telescope-enters-final-commissioning-phase/ NASA’s Nancy Grace Roman Space Telescope mission has now entered the science commissioning phase, having successfully completed a comprehensive checkout and refinement of the observatory and primary instrument performance.

NASA’s Dragonfly Completes First Simulated Flight

https://science.nasa.gov/blogs/dragonfly/2026/10/23/nasas-dragonfly-completes-first-simulated-flight/ Separated from its protective backshell, NASA’s Dragonfly rotorcraft autonomously speeds over the sand dunes of Titan. It scans the terrain below, searching for a safe place to land. When Dragonfly discovers a safe site, it turns, descends, and lands at the selected location, touching down for the first time on the surface of Saturn’s largest moon.

NASA’s Swift Mission Ends, Leaves Behind Scientific Bonanza

https://science.nasa.gov/missions/swift/nasas-swift-mission-ends/ NASA’s Neil Gehrels Swift Observatory has ended its science mission now that the spacecraft is orbiting less than 171 miles (275 kilometers) above Earth’s surface. The greater atmospheric drag at this height prevents the satellite’s telescopes from steadily gazing at their astronomical targets.
