"The mirror is like a very precise funnel for X-rays. If any part of the funnel is even slightly out of place, the X-rays miss their target and the image blurs. It must also survive the intense vibrations of a sounding rocket launch while retaining its optical precision." — Ikuyuki Mitsuishi, Nagoya University

Leading continued development; preparing upgraded mirror for FOXSI-5

For a quarter century, one telescope has dominated X-ray astronomy: NASA's Chandra, a bus-sized, $1.65 billion observatory with mirrors 1.2 meters across. Now a team from Nagoya University and Japan's SPring-8 synchrotron has produced a single seamless nickel mirror just 60 millimeters wide that matches Chandra's core sharpness — resolving an object 3.5 millimeters wide from a kilometer away. The mirror flew on the FOXSI-4 sounding rocket in April 2024 and captured images of a solar flare.
