The amateur radio satellite ARISSat-1, deployed from the ISS on August 3, fell silent on Wednesday, January 4, as it re-entered the Earth’s atmosphere.

The ARISSat website shows the last telemetry was captured at 06:02:14 UTC on Jan. 4  with these temperatures:

IHU PCB    75°C
PSU     76°C
RF     88°C
Batt     55°C
RF Enc 67°C

Mike Repprecht DK3WN reports that Tetsurou Satou JA0CAW captured telemetry at 05:59 UTC. Mike says it’s remarkable that the last voice message heard was from Yuri Gagarin.

Konstantin Vladimirovich RN3ZF listened for the satellite at 08:42 UTC using an AMSAT-UK FUNcube Dongle with WRplus. On the FUNcube Yahoo Group he says “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.” He continued monitoring but did not detect any further signals from the satellite. He has made available his final ARISSat-1 recordings in WRPlus format at:

Note the files are large.

Education has been a large part of the ARISSat project and on the FUNcube Yahoo Group Simon Kennedy G0FCU says he was glad he was able to receive good signals and SSTV pictures last week for his daughter to take to school as part of her project on Space.
