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.

The ARISS Hamvention booth is open for business today in the Volta building! It's your chance to get a 25th anniversary logo t-shirt or challenge coin. We love your questions too! As us about STEM contacts, APRS, or whatever is on your mind! See you there!

Axiom Mission 2 pilot John Shoffner, KO4MJC, will do a post-forum meet-and-greet in the area behind the ARISS booth starting shortly. Find us in the Volta building (4).

Good morning from @hamvention! Be sure to check out the booth, satellite pass demos this morning. Forums today include @ARISS_Intl at 1:10pm and the AMSAT forum at 2:30pm, both in Forum Room 2. A livestream will be available at youtube.com/live/CRDAQx-Vg…

Grab your lunch then head over to Forum Room 2 - you have one hour to go before the ARISS forum. It's all about 25 years on the ISS, and looking to the future beyond the station. Special guest John Shoffner will talk ARISS' involvement in commercial space too! See you there!

ARISS is bringing the Radio Adventure to Dayton Hamvention today. In our don't-miss forum at 1:10 today meet adventurer John Shoffner, KO4MCJ, who will talk about his ham radio adventure onboard the International Space Station! Don't miss our booth in the Volta building too!

Here's a look at the menu of all the great things ARISS will offer at Dayton Hamvention 2026! See you this weekend for some Radio Adventure!

ARISS-USA is seeking an experienced educator with extensive leadership experience to help us expand our mission to connect kids to astronauts in space through amateur radio. The application window is now open for our next Director of Education, a part-time, US-based, remote position. See the graphic and visit ARISS.org for more info.

More visits today to Newton Park Primary after visiting Bower yesterday. Lots of good questions. 📷How astronauts can sleep without a bed? 📷How do we know where the Space Station is? 📷What's a Capri Sun got to do with the ISS? 📷Why do you need such a big antenna? @ARISS_Intl

ARISS APRS is online and will be running on 437.825 MHz when available. If you’re running an ARISS APRS iGate, tune it over to the new 70 CM frequency please!

Day 2 of setup is complete. Can't wait for tomorrow 🚀🛰️📡 #amsat #hamradio #faba Fantasy Basel - The Swiss Comic Con @CubeSatSim @ARISS_Intl

@ARISS_Intl @Space_Station 6 associates members of SCAN International from the Philippines listening to the Astronaut Sophie Adenot, KJ5LTN using the callsign OR4ISS while calling the station of JR5YED and answering the students from Tobe Junior High School in Tobe Japan.

Reminder - the HamTV unit on the ISS will be off for the next week or so. This is in support of other experiments on the ISS. Detailed times in the graphic.

The SSTV Series 32 event "World Peace" is set to end in about 2 hours (16:40 UTC | 12:40 PM ET). We still want your images and plan to issue certificates. See the graphic for more details.

HamTV will be off-line beginning Wednesday for about a week in support of other payload activities on the International Space Station. Detailed times in the graphic.

@david_trolinger @EB2GGT_Guiller @F5RRO_Olivier @issfanclub The Columbus Module can use several different ones, NA1SS and OR4ISS are most frequently used. The Service Module radio typically uses RS0ISS.

@EB2GGT_Guiller @F5RRO_Olivier @ARISS_Intl @issfanclub Is is only the "RS0ISS International Space Station" ID

Nice RX pictures from ISS but she is not a number at the last end trame ... and you ? @ARISS_Intl @issfanclub #iss #sstv #amsat

@EA4HLB @EB2GGT_Guiller @F5RRO_Olivier @issfanclub Teams are aware, thanks.

@EB2GGT_Guiller @F5RRO_Olivier @ARISS_Intl @issfanclub Right, APRS frames are being sent right at the end of each image.

@Gilles_Platret_ @F5RRO_Olivier @issfanclub We believe it is 12 but are confirming with the ARISS Russia team. As mentioned last week, this one came together a little more quickly than other that get planned.

@F5RRO_Olivier @ARISS_Intl @issfanclub Pas de numérotation, et on est même pas sur du nombre d'images (12 ?) ....

The ARISS Russia team organizes all the ISS SSTV events and the transmissions come from the radio in the Russian Service Module. Teams from ARISS USA contribute, and help manage things like the Image Gallery. It's a collaborative effort and different events can have a different experience.

@LU3HAU @ARISS_Intl Bonita captura. Como le dije a @SV2HWM Merkouris, este evento con dibujos infantiles se me hace como si fuese el UMKA-1. Estaba acostumbrado a que los eventos de ISS tuviesen otra temática, es como si UMKA-1 hubiese "tomado el control" de la ISS, jajaja.

Our teams are making their final preparations for a busy Dayton Hamvention next weekend! We've got exciting announcements in our forum, plus an astronaut, new items to buy and plenty of people to answer your ARISS questions. See you starting Friday!

Just a reminder for those participating in the SSTV Series 32 event. The ARISS SSTV Image Library is currently off-line. Please hold your image decodes, we will announce when to upload them and the certificate details when the site returns.
