I am very concerned about this news.
Iran is a very hostile nation...

Yes! Iran has launched what it calls a communications satellite.

But if it is indeed a crude LEO comsat, perhaps meant only to broadcast
Shiite Muslim propaganda from orbit from an onboard endless-looping
tape-recording, then one can estimate that the Iranian satellite weighs
at LEAST 100 kilos [220Ibs].

They are not far from the day when they will have the missile capability
to launch a small nuclear warhead a distance over 1,500 kilometers; far enough
to reach Israel.
The Middle-East could go up like a tinderbox any year now.
