SSETI Express satellite goes silen



REPRINTED FROM ARRL BULLETIN

* SSETI Express satellite goes silent: The Student Space Exploration and
Technology Initiative (SSETI) Express satellite, sent into orbit from Russia
October 27, was reported silent at week's end. "We have not heard anything
from Express on UHF since last night [October 27] when the telemetry seemed
to indicate a very negative power budget," Graham Shirville, G3VZV, said on
the AMSAT BB as he was departing Russia following the launch. "If it does
not recover then it will be a sad end to a wonderful mission." Shirville
said ground controllers were going to attempt a blind command of the
satellite over the weekend in an effort to revive the satellite, which
carries an Amateur Radio package and three CubeSat picosatellites. The
spacecraft had been transmitting AX.25 telemetry at 9k6 bps on 437.250 MHz.
Plans call for the satellite will be turned into a single-channel amateur FM
voice Mode U/S transponder after the transmitter serves initial telemetry
duty. The AMSAT-UK <http://www.uk.amsat.org/> and AMSAT-NA
<http://www.amsat.org/amsat-new/satellites/sat_summary/SSETI.php> Web sites
have additional information on this European Space Agency-sponsored project,
in which SSETI Express was built by a distributed team of university
students and radio amateurs throughout Europe. Additional details are on the
SSETI Express Web site <http://sseti.gte.tuwien.ac.at/express/mop/>.
