Actualización sobre el repetidor de voz de ARISS: Somos conscientes de los informes que indican que el repetidor de voz en banda cruzada no ha vuelto a estar operativo tras el contacto de hoy con Florida. El equipo de operaciones de ARISS está trabajando con el equipo responsable de las cargas útiles de la ISS para enviar un mensaje a la tripulación, solicitando que la radio vuelva a su configuración habitual de repetidor. Esto dependerá de la disponibilidad de la tripulación y podría no producirse hasta el viernes. Mientras seguís el evento SSTV en curso, os animamos a compartir cualquier novedad que detectéis sobre la actividad del repetidor de voz. ¡Gracias por vuestra paciencia!

When you go around the world every 90 minutes for more than 6 years, you log some miles. World Space Week is a great time to look back to 2020, the initial install of the ARISS InterOperable Radio System. Now celebrating a journey of more than 1 Billion Miles! (Or 1.6 Billion Kilometers!) What an achievement!
Informational ARISS graphic highlighting the InterOperable Radio System (IORS) aboard the International Space Station. The left side shows a close-up photo of IORS radio equipment installed inside the ISS Columbus module, including radios, cables, connectors, and mounting hardware. The right side features a dark blue background with the title “ARISS IORS” and text explaining that ARISS began upgrading ISS radios in 2020 with the new InterOperable Radio System. The graphic states that the Columbus Module radio shown has traveled more than 1 billion miles in orbit while supporting countless FM voice repeater contacts, and that a companion radio in the Russian Service Module has supported APRS and SSTV operations since August 2022. An ARISS logo appears at the bottom.
