ARISS - Amateur Radio on the ISS

ARISS is plotting a course to continue our mission in the government and commercial space realm beyond the targeted decommissioning of the ISS in the 2030 timeframe. Read more about our activities in these infographics, and in a blog post at ariss.org.

Today's contact with California will be streamed from the event at live.ariss.org or youtube.com/live/rT4NiKPTM…. Downlink audio on 145.800 MHz FM should be audible in parts of Europe during this pass.

1 hour until contact with California! Students at the Lewis Center for Educational Research in Apple Valley will talk with Sophie Adenot, KJ5LTN, on the ISS via ham radio. Sched. today at 17:15 UTC | 1:15 PM ET | 10:15 AM PT via IK1SLD telebridge. Listen on 145.800 MHz FM.

Just a few more hours until the cross band voice repeater comes back online following today's ISS spacewalk. Also tomorrow, it's a STEM contact with California via a ground station in Italy - we call that a telebridge contact.

@PrashantSaswad4 Instructions vary by part of the world, but they all require postal mail. Follow the link in the post for more information.

@ARISS_Intl Do I need to like Gmail it or send by Post?

Yes, you can get a QSL card for your ARISS contacts - your card gets ours. Visit ariss.org/qsl-cards.html for more info and check the requirements for your part of the world.

@orionlensguy Yes, they typically happen each time. This particular one is longer because it also encompasses the Progress undocking.

@ARISS_Intl Appreciate the schedule! Quick question - do these radio outages happen before every EVA?

1 hour until ARISS radio outages begin. Due to a planned Progress ship undocking today and spacewalk Wednesday, radios will be off until Thursday. Check the graphic for details.

Mon-Thu the voice repeater will be offline in support of activities on the station. When things start back up Thursday, listen in Europe for the downlink on California's contact.

Contact upcoming with California! Students at the Lewis Center for Educational Research in Apple Valley will talk with Sophie Adenot, KJ5LTN, on the ISS via ham radio. Sched. Thu. 19-Mar at 17:15 UTC | 1:15 PM ET | 10:15 AM PT via IK1SLD telebridge. Listen on 145.800 or watch on YT.

Since it's a #FollowFriday why not come give the ARISS Discord a try. Join our 1,000+ members in discussions about ham radio activities on the ISS and our STEM initiatives. discord.gg/X8HXh8XsFh

My most intriguing space contact was with "my friend" commander Valery Korzun, when he was on the ISS. It was almost midnight, and he wasn't not supposed to be on the radio 😂@ARISS_Intl #hamradio #amsat Listen: ct1ete.net/audio/RS0ISS_V… photo: Wikipedia

🚀 Big news! Astronaut John Shoffner, KO4MJC (Ax-2 pilot), will join us as special guest at ARISS @ Dayton Hamvention 2026! STEM inspiration from orbit straight to Dayton. Stay tuned for details! #Hamvention2026 #ARISS #AmateurRadio

ARISS radio outages planned for next week. Due to a planned Progress ship undocking Monday and spacewalk Wednesday, radios will be off Monday to Thursday. Check the graphic for details.

We invite educational groups in Europe, the Middle East, and Africa to apply for amateur radio contacts with the ISS crew. Visit ariss-eu.org to find out more and review the application process. Applications are due in a little over 2 weeks, so don't wait!

Artemis II could launch as early as April 1, no fooling! Radio amateurs from ARISS and @AMSAT will be working with NASA SCaN to track the radio emissions of the space craft. We call that AREx, and it's one of the ways ARISS is looking beyond the ISS. More on our website.

ARISS offers future human spaceflight missions proven flight certified hardware. This functions as backup comms for emergencies, communications for crew morale, and space based learning experiences. Read our Beyond the ISS article on the ARISS website for more.

ARISS is looking to the future by building commercial space relationships today. We're proud to work with groups like Fram2 and Axiom to continue our amateur radio in human spaceflight mission. Check the ARISS website for our "Beyond the ISS" article that looks more broadly into the future of ARISS.

As we continue to watch the evolution of ARISS beyond the ISS, an article came onto our radar. ArsTechnica is reporting about discussions by US lawmakers on ties between commercial station establishment and the decommissioning of the ISS. Full article linked below.
