thank you Nico i like the way you can rotate the earth and see the cloudy skies (the milky way) in Celestrak. (hold left button and move pointer) can we send a few iRobot /roomba vacuums up there to clean it up? just add the solar panels, batteries and some CPU, a ham xcvr and AMSAT can take care of this, right? they could goto the ISS for recharge/homeing? heck we could add FM/linear transponders and everybody is happy. 73 KFoG cm88pk
