Bouncing data off the International Space Station

For the first time, I tried my hand at relaying a digital packet signal through the amateur radio system aboard the International Space station as it passed over Mississippi around 8:30pm on June 6, 2013.  The packet I sent was successfully heard and relayed, and is highlighted below.  The line shows the signal sent by my station, K5JAW-1, being relayed by RS0ISS-4, which is the Russian call sign for the International Space Station's amateur packet station.  The time stamp shows June 7, 2013 01:30:15, which is Universal Coordinated Time, the international standard time for amateur operators.  This is my second contact with the ISS.  The first was a voice contact on November 7, 2010.  You can listen to that contact by clicking here.

Below you'll find a screen-capture of a map produced by www.ariss.net, which plots stations heard by the International Space Station.  You'll note KC5WQ-2 near Itta Bena, and some of his packets are also listed below.
