*ARISSat-1
Satelliten sänder fortfarande på 145.950. fina passager på kvällarna med
många bilder
*Soyuz uppskjutningsproblem.
I veckan gick en del proviant och reservdelar till instrument förlorade då
en av dom annars så tillförlitliga raketerna fick problem med ett steg och
kunde ej nå sin bana på väg till ISS.

*SO-67
Satelliten har fått problem och vi avaktar mer infromation
*AO-51
En andra cell i batteripacken är på väg att ge upp och nu blir det mer och
mer aktuellt med FOX satelliten som ska ersätta den populära FM satelliten.
Det verkar som att FOX ska delas upp i FOX-1 samt FOX-2 ( FOX-1 ska snabbt
ersätta AO-51.)
*HO-68
Hörs bara beacon och ingen information. (Nu verkar även hemsidan ha
försvunnit,,,)
*Asteroid ( Se upp,,,)
En rolig utmaning framåt hösten att höra ekona från asteroiden när den drar
förbi jorden.
The 400 meter diameter near-Earth asteroid 2005 YU55 will be making
a 0.85 lunar distance flyby of Earth on November 8. Michael Busch at
the UCLA Department of Earth and Space Sciences notes this may an
opportunity for amateur satellite operators to observe the fly-by.
UCLA will be conducting an extensive campaign of radar observations
with the Arecibo Observatory, the Deep Space Network Goldstone facil-
ity, and the Green Bank Telescope and the Very Long Baseline Array.
Because YU55 will be so close to Earth, its radar echo will be
detectable with even small antennas (~1 m^2). YU55’s echo will be
a slowly drifting signal with a bandwidth of ~1 Hz within a few kHz
of 2380 MHz or 8560 MHz.
This will present amateur radio operators an opportunity to receive
the radar reflections off of the asteroid because of the big dish,
big signals originating from Arecibo and Goldstone.
On November 8, 2011, 19:15 – 19:30 UTC, Arecibo will be transmitting
a continuous wave tuned to put the asteroid’s echo at a constant
2380.000000 MHz at the Green Bank Telescope. Observers elsewhere on
Earth will see the echo within 2 kHz of 2380 MHz, Doppler-shifted by
the Earth’s rotation. It will be slowly drifting in frequency and
have a bandwidth of ~0.6 Hz.
On November 9, 2011, 01:30 – 02:00 UTC, the Goldstone Deep Space Net-
work facility will be be transmitting a continuous wave tuned to put
the asteroid’s echo a constant 8560.000000 MHz at a second antenna at
the Goldstone site. Other observers may see the echo shifted by as
much as 6 kHz, and it will have a bandwidth of ~2 Hz.
Initial information can be found on-line at:

More details will be announced as the fly-by date approaches.
En god vecka tillönskas!
