Yesterday, the Artemis II mission surpassed the distance record set by Apollo 13 during its lunar flyby.
These images, captured by our nanosatellite SONATE-2, show the Moon rising over Antarctica: Our closest neighbor, seen from orbit.
Godspeed to the four astronauts on their journey back to Earth.

Both platforms were traveling at approximately 7.6 km/s, resulting in a high relative velocity and a very limited observation window.
The image was acquired at a distance of roughly 150 km.

Captured in motion: our nanosatellite SONATE-2 successfully imaged the International Space Station (ISS).

The first image is magnified for improved visibility, the second image shows the original capture.

A small contribution to the amateur radio community by our CubeSat SONATE-2: from Jul 2024–Jan 2026 we relayed 44,365 APRS packets 🎉
This animation shows their monthly global distribution🌍📡🛰️

APRS = small ham-radio digital packets (position/status/telemetry).

At the Winter Satellite Workshop 2026, we presented the Apophis Interceptor mission concept.
It demonstrates the potential of small satellites for flexible, rapid-response, and cost-efficient asteroid reconnaissance. 🚀

The JMU Space-Observatory photographed the 3rd known interstellar comet 3I/ATLAS currently visiting our solar system!
What you see is a stacked image from over 2h of footage by our telescope (D69) at the University of Würzburg.
You can nicely see the tail of the comet towards the upper right!

At the ZARM drop tower, we recreated Martian conditions and our maple-seed-like vehicles achieved Autorotation. Even real maple seeds spun! 🍁
First autorotation tests under extraterrestrial conditions—paper coming soon!
