The launch date of September 27th and a lift-off time of 06:52:26 UTC now looks pretty certain for the Cosmos 3 rocket carrying SSETI Express with its three cubesat passengers and four other satellites into orbit.
Updated pre-launch keps will be made available in a few days time and there are a number of web pages being developed to enable amateurs to locate SSETI Express, receive and download the telemetry and to forward it to Mission Control for their evaluation. Later in the mission it will also be possible for amateurs to transmit so-called friendly commands to request particular
telemetry or thumbnail pictures.
The SSETI team and ESA – The European Space Agency, are very keen to recruit as many radio amateurs as possible around the world to capture the telemetry. Our worldwide virtual groundstation network is a unique
facility which we can use to our benefit as well as theirs. By showing how well our network can substitute for their expensive professional one, we will really encourage them to include amateur transponder systems in their
future missions.
ESA will be offering a very significant prize for the amateur who sends them the largest amount of telemetry during the mission and is also offering a unique I heard it first T shirt to the station that sends them the first
report. This is actually likely to be one of the three Stations that we hope to having listening for SSETI Express in Antarctica – an ideal item of clothing for their forthcoming winter season!
The main mission site is being finalised and can already be accessed at www.sseti.net — click on the express mission operation web site link. This has full details of the mission, the software, present orbital position
and a host of other information.

The SSETI Express Mission Pages at:

has a short report with some photos of the work being done at the assembly facility at the Plesetsk Cosmodrome assembly facility. Both the UHF and S band units have been tested and all appears ok so far. Please continue to keep those fingers crossed for us

SSETI Express Handbook Free Download
The Student Space Exploration and Technology Initiative was started by the European Space Agency (ESA) Education Office to enable University students in Europe to experience the challenges and opportunities of actually building a satellite and having it launched into space.
Their first satellite SSETI Express is scheduled for launch on September 30th from Plesetsk in northern Russia at approx 06:52 UTC. It is planned to downlink telemetry in AX25 format at 9k6 on 437.250MHz and at 38k4 on 2401.835MHz. It should also be available for Radio Amateurs to use as a single channel FM transponder.
To coincide with the launch the SSETI Express Handbook has just been published. Written by Richard Limebear G3RWL, using ESA and AMSAT-UK documentation, the 22 page handbook covers just about every aspect of this exciting new spacecraft. It details AMSAT-UK s involvement in the project and contains a wealth of technical information about the spacecraft and the 3 Picosats that will be
launched from it.
ESA has asked for the help of Radio Amateurs around the world to collect vital telemetry data from the satellite and they are organising a competition with a prize for whoever submits the largest number of valid telemetry payload packets to SSETI Express Mission Control by 1 January 2006. The handbook provides full details of how to enter this competition.
The PDF of the handbook can be downloaded free of charge from the AMSAT-UK website at http://www.uk.amsat.org/ or printed copies are available for 5 inc P&P in Europe from AMSAT-UK, Badgers, Letton Close, Blandford, Dorset, DT11
7SS. Tel: +44 (0)1258 453959 Email: g3wgm@amsat.org . Cheques should be made payable to AMSAT-UK. Postage rates for other parts of the world available on request.
A French version of the handbook translated by Christophe Candebat F1MOJ is also available.
