ARISSat-1 KEDR Goes Silent

Reception reports indicate that ARISSat-1/KEDR has stopped transmitting on Wednesday, January 4, 2012. The last full telemetry captured and reported to the ARISSatTLM web site at 06:02:14 UTC on January 4 were received from ground stations as the satellite passed over Japan.

You can view the full telemetry display or the condensed telemetry display.

Telemetry reports showed that the temperature aboard ARISSat-1/KEDR had been rising as atmospheric drag began to affect the satellite. Final temperatures received via ARISSatTLM reported this data:

IHU 75 ° C / 167.0 °F
PSU 76 ° C / 168.8 °F
RF 88 ° C / 190.4 °F
Control Panel 61 ° C / 141.8 °F
Experiment 64 ° C / 147.2 °F

Stations receiving telemetry from ARISSat-1 at any time over the last few months, please forward all of your .CSV telemetry files to telemetry AT

Konstantin, RN3ZF sent a reception report of his copy of the 0842 UTC pass that, "the telemetry was absent, voice messages were not legible, very silent and interrupted. Most likely, I saw last minutes in the life of the satellite."

Dee, NB2F reported, "Nothing heard from ARISSat-1/KEDR on any frequency during the first USA pass at 16:00 UTC, January 4."

ARISSat-1/KEDR was deployed from the International Space Station on August 3, 2011 during during EVA-29 on by Cosmonaut/Flight Engineers Sergei Volkov and Alexander Samokutyaev.

The satellite carried a student experiment from Kursk State University in Russia which measured atmospheric density. Students from around the world provided the voices for the FM voice announcements.
