July 3, 2025—Amateur Radio on the International Space Station (ARISS) has received schedule confirmation for an ARISS radio contact between an Axiom Mission 4 (Ax-4) astronaut aboard the International Space Station (ISS) and students at the University of Wrocław located in Wrocław, Poland. ARISS conducts 60-100 of these special amateur radio contacts each year between students around the globe and crew members with ham radio licenses aboard the Space Station.
The University of Wrocław offers a comprehensive educational profile across a wide range of disciplines, including the natural sciences, humanities, social sciences, and law. The university places particular emphasis on physics and astronomy, supported by dedicated research teams and state-of-the-art facilities such as the Astronomical Institute and specialized physics laboratories. These departments are actively involved in both theoretical and applied research, fostering interdisciplinary collaboration and innovation.
The University of Wrocław is deeply committed to popularizing science and making scientific knowledge accessible to the public. A prime example of this is its participation in the Lower Silesian Science Festival, where the Faculty of Physics and Astronomy organizes events such as the “Physics Circus” and a series of lectures and hands-on activities that vividly demonstrate complex physical phenomena.
The university also hosts a variety of public science events, such as the “Night of Biologists,” which invites participants to explore the wonders of biology through lectures and interactive workshops. In 2025, the university took part in the “Long Night of Museums,” opening its facilities to the public and showcasing exhibitions that highlight the intersection of science and culture.
This will be a telebridge Contact via Amateur Radio allowing students to ask their questions of astronaut Sławosz Uznański-Wiśniewski, amateur radio call sign SQ7AS The downlink frequency for this contact is 145.800 MHz and may be heard by listeners that are within the ISS-footprint that also encompasses the telebridge station.
The ARISS amateur radio ground station (telebridge station) for this contact is in Greenbelt, Maryland. The amateur radio volunteer team at the ground station will use the call sign, K6DUE, to establish and maintain the ISS connection.
The ARISS radio contact is scheduled for July 4, 2025 at 10:41 am CEST (Wrocław, Poland) (8:41 UTC, 4:41 am EDT, 3:41 am CDT, 2:41 am MDT, 1:41 am PDT).
The public is invited to watch the live stream at:
