ARLA/CLUSTER: RE: ARISSat MORREU !

[João Gonçalves Costa]

ARISSat-1 SK

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 January 4 with these temperatures:
IHU PCB 75°C 
PSU 76°C 
RF 88°C
Batt 55°C 
RF Enc 67°C

The full telemetry data can be seen at http://www.arissat1.org/


Mike Repprecht DK3WN reports that Tetsurou Satou JA0CAW captured telemetry at 05:59 UTC. Mike says it's remarkable that the last heard voice message was from Yuri Gagarin. See the last data on Mike's SatBlog http://www.dk3wn.info/p/?p=25125


Konstantin RN3ZF listened for the satellite at 08:42 UTC and reported:
FCD + WRplus I observed satellite ARISSat-1 on a falls. The telemetry was absent, voice messages were not legible, very silent and interrupted. 
Most likely, I saw last minutes lives of the satellite, ARISSat-1 is dead. The subsequent monitoring of frequency speaks that the satellite any more does not radiate. 

Here last my radiomonitoring in format WRPlus:

Education has been a large part of the ARISSat project and on the AMSAT bulletin board Simon G0FCU says he was glad he was able toreceive good signals and SSTV pictures last week for his daughter to take to school as part of her project on Space.

TIP Reports for Object 37772, RADIOSCAF-B (KEDR) - Final Report
-----------------------------------------------------------------
Report Date/Time 2012-01-04 04:28:00 GMT Predicted Decay Time 2012-01-04 07:00:00 GMT +/- 3 Hours Predicted Decay Location 12.7° S, 354.3° E Direction ascending Inclination 51.6° Revolution Number 2411  (por DK3WN)

A passagem das 06:18 a 06:23 local aqui em Sete Lagoas não foi escutada por mim ! 

Deveria ouvir pelo menos 1 mn antes do LOS, 14 mn apos a saida do eclipse, na #2412.

Ultima telemetria sobre o Japão em 04 Jan 2012 06:02:14 UTC na #2410.

A temperatura da bateria estava em 55 graus, a unidade de RF em 88 graus !!!

A  passagem #2411 não foi ouvida por ninguém, assim como a #2412 sobre a Europa e Asia...


Que pena: o que é bom dura pouco !!!
