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!

Finally SONATE-2's #SSTV transmitter 🛰 is active again, sending 2 different images taken from orbit.
The #APRS digipeater will be switched off during that period (05.12.25 15:30 - 08.12.25 15:00 UTC).

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!

Wednesday night, our SkyCAM system at the BlueBox in Hessdalen captured a possible meteor or space debris reentry. A similar system, SkyCAM-7, operates at Zugspitze’s Schneefernerhaus in the context of VaMEx-3 MarsSymphony.

SONATE-2 ist ein 6U Cubesat (ca. 300 x 200 x 100 mm³). Wir konnten ihn sogar mit unseren eigenen Teleskop tracken. Dabei ist diese Aufnahme entstanden. 🛰️🌟

SONATE ist der Vorgängersatellit, der an der Professur entwickelt wurde. SONATE-2 ist mit der NOARD Catalog Nummer 59112 bzw. dem Int. Designator 2024-043Q auffindbar.

Satellite image of the Gamsberg mesa in Namibia, captured by our Nanosatellite SONATE-2 on January 13, 2025, 12:39 UTC.

A heartbreaking view from space of the Los Angeles fires, with smoke billowing into the sky like clouds. 🌍🔥
A stark reminder of the destructive power of wildfires and the urgent need for climate action.
