July 7, 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 Mobilis Interactive Science Center located in Győr, Hungary. 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 Mobilis Interactive Science Center, opened in 2012 and is primarily visited by school groups, families, teachers and university students, but it also hosts a wide range of events and programs for the general public. One of its key missions is to inspire young people to pursue careers in science and engineering and to promote scientific thinking across all age groups. The center uniquely combines play, learning, and discovery by offering interactive exhibits, spectacular science shows, and creative workshops that introduce visitors to the fundamentals of physics, chemistry, biology, and computer science.

This will be a Multipoint Telebridge Contact via Amateur Radio and students will take turns asking their questions of astronaut Tibor Kapu, amateur radio call sign HA5TRO. 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, U.S. 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 9, 2025 at 9:49:40 am CEST (Hungary) (7:49:40 UTC, 3:49 am EDT, 2:49 am CDT, 1:49 am MDT, 12:49 am PDT).
