A high‑resolution spectral map of asteroid 165 Eugenia revealed a previously undetected phyllosilicate band at 0.69 µm , indicating that the asteroid’s surface had undergone aqueous alteration far more recently than models predicted. This finding suggested that water‑rich minerals could be more common in the inner belt than previously thought. 3.2 Dust Dynamics – The “Whispers” of the Belt While imaging, the Dust‑Probe logged 2,400 micro‑impact events per hour , each corresponding to particles roughly 5–15 µm in diameter. By correlating impact timing with the spacecraft’s position, the team derived a three‑dimensional density map of fine dust.

Although the magnetometer’s resolution was coarse, it opened a new line of inquiry: could be performed by future nanosatellites to map the internal structure of small bodies without landing? Chapter 4 – Return and Legacy 4 Years After Launch On June 18, 2039 , with its battery nearing end‑of‑life, SONE‑059 executed a final delta‑v burn to place itself on a sun‑synchronous trajectory that would bring it within 0.03 AU of Earth in early 2040. The mission team decided to de‑orbit the probe safely, ensuring it would burn up in the atmosphere, adhering to the Space Debris Mitigation guidelines. SONE-059
