From first student contacts with astronauts aboard the ISS to reaching learners around the world, the ARISS and NASA partnership has inspired generations through STEM education and amateur radio.

Graphic announcing a new 4-year Space Act Agreement between NASA and ARISS. A timeline on the left highlights the partnership's impact across four decades. The 2000s section shows an astronaut using amateur radio aboard the International Space Station, labeled "First Contacts from ISS." The 2010s section shows a student using amateur radio equipment, labeled "STEM Engagement." The 2020s section shows an astronaut conducting an amateur radio activity aboard the ISS, labeled "Global Reach." The 2026-2030 section shows a document titled "4-Year Space Act Agreement" with the ARISS logo and a pen, labeled "The Next 4 Years." Text on the right announces the signing of a new 4-year Space Act Agreement with NASA, extending a partnership that began in 2000 with the ISS's first educational payload and will continue inspiring students through STEM learning, amateur radio, and space exploration.

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 IORS Now celebrating a journey of more than 1 Billion Miles! (Or 1.6 B 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.
