SPACE Audio Recordings: ARTEMIS II Mission and ISS Public Audio

The SPACE Amateur Radio over Internet Protocol (RoIP) systems provide public audio transmissions from Mission Control and Astronauts for educational purposes. This service primarily streams NASA public media sources, including Artemis II and the ISS public audio channel 2 feed, which mainly features English communications. Astronaut activities on the ISS typically occur between 0700 UTC and 19:00 UTC, with transmissions most common during early mornings USA time. Special events like launches or spacewalks are also included. Users can connect via EchoLink to the *SPACE* conference, via IRLP to the 0100 experimental reflector, or via Allstar to node 516221. The service notes that long periods of silence are common and that NASA audio sources can be periodically unavailable or noisy. Recordings of transmissions are published at space.rfnet.link/recordings/. EchoLink connections use the GSM CODEC, while IRLP and other connections default to uncompressed or u-law CODEC.
