NASA’s Asteroid Hunter Gets Its Shield
Ground-based telescopes are blind to asteroids hiding in the fierce glare of the Sun. Fixing that blind spot requires a space telescope that can look directly toward our star without cooking its own instruments.
Ground-based telescopes are blind to asteroids hiding in the fierce glare of the Sun. Fixing that blind spot requires a space telescope that can look directly toward our star without cooking its own instruments. NASA has taken a major step toward that goal by inspecting the massive sunshade built for the Near-Earth Object Surveyor mission.
Standing 20 feet tall, the towering structure features dark, patterned cells designed to keep the infrared space telescope cold while simultaneously generating power for the spacecraft. Our read suggests that dual-purpose design highlights how deep-space engineering must merge thermal defense with power generation when every square inch counts. Operating in the harsh environment near the Sun leaves zero margin for error in managing heat and electricity.
Watch for how the mission handles final integration as NASA prepares the infrared hunter to track down some of the hardest-to-find comets and asteroids in our solar system.
