    Hello everybody,
    
    On Friday night, Sept. 21, 21:00 EDT (Sept. 22, 01:00 UT) mission Kodiak Star
    will launch from Kodiak island in Alaska. The launcher is an Athena I three
    stage rocket (2 stages + Orbit Adjust Module) and the payload is made of four
    satellites. The primary payload is the NASA sponsored Starshine 3 student
    tracked atmospheric research satellite. I've worked many hours on the
    construction of this satellite and I'm surely looking forward to its launch.
    
    It is an aluminum sphere painted in black, 94 cm in diameter, 90 kg mass, and
    covered with 1500 aluminum mirrors 2,5 cm in dia., seven solar cell clusters and
    31 laser retroreflectors. The sunlight reflected off these mirrors will produce
    flashes that will be seen naked eye ( http://www.azinet.com/starshine/ )
    
    The other satellites are the DoD sponsored PICOSat, SAPPHIRE and PCSat. They
    will be too small to be seen naked eye and may be too faint for binoculars too.
    The mission profile is quite unique as the OAM will first reach an altitude of
    800 km, release PICOSat at T+ 01h 03m 50s, SAPPHIRE at T+ 01h 09m 38s and PCSat
    at T+ 01h 10m 37s (all times approximate) while cruising off the african east
    coast. The stage will then descend to 500 km altitude and release Starshine 3
    over the South Pacific at T+ 02h 08m 21s. Following the release, the OAM will
    distance itself from the satellite and make an evasive burn to fuel depletion
    over central Africa. For a ground track of the first two orbits :

    But the launch is likely to be delayed for maybe two days because of bad
    weather. Chances for a launch on Friday are only at 20 %. They rise to 30 % on
    Saturday, but 70 % on Sunday. Just in case, I've produced TLEs for the three
    days assuming a launch at the opening of the window that lasts from 01:00 to
    03:00 UT on each day :

    From my place, I have no visible passes before Sept. 26 given a launch on the
    21st. :-(
