Opportunities for monitoring tv downlink frequencies

[pberrett]

Hi all

Some time ago NASA integrated a camera on the Shuttle's main tank and I tried to receive the camera tv transmissions which were unencrypted here in Melbourne Australia. I failed, but this was due to the path of the main tank going below my horizon. before the flight I posted here and was surprised to receive an email from NASA asking
 if I could pass on any footage I was able to receive.
 
My position in Melbourne is fortuitous because in many cases 1 hour after launch a commercial vehicle chasing the ISS will pass near here.

I noted from the Spacex launch that they integrated a camera into what I think was the second stage. This spurred me into thinking that maybe the transmission could be received here. I have since been told by a Spacex employee that the transmissions are encrypted so no dice there.

Are readers aware of any other forthcoming opportunities for me to receive tv transmissions from commercial vehicles heading to the ISS? Cygnus perhaps? 

Thanks Peter

All encrypted

There is encryption and hard-encryption.
hard being >= 1024 bits.
Anything under and some good open software decryption tools should be able to crack it in a reasonable length of time.

1024 bits is for public key encryption.
You will find 128 bit private key unbreakable.
