ARISS received new Fram2 spacecraft trajectory data today and TLEs derived from this data matched the current Space-Track TLE exactly. This Two Line Element (TLE) data is available on the ARISS website at ariss-usa.org/keps.txt and at ariss.org/keps.html.

A Fram2Ham SSTV update from @Ariss_chair earlier today: Recent changes in the crew's sleep schedule means that the US/Canada pass planned for later tonight will not occur. We apologize for this change and hope you understand that space operations are always dynamic in nature.

Both the ARISS crossband voice repeater and the packet radio (APRS) appear to be off-line. The appropriate ops teams are aware and investigating.

The crowd at amsat.org/status is reporting the crossband voice repeater is back online. Listen to the repeater on 437.800 MHz (+/- Doppler Shift). Use 145.990 MHz (PL 67 Hz) for your uplink.
