I remember that during previous shuttle launches crew/ground communications were rebroadcast on a shortwave frequency from NASA's Goddard Center. Will this continue with the next launch (which I heard will use encrypted trans- missions) and (Kenneth) what is the frequency? Thanks. -- "The duality of man.

I wonder if you noticed that item in the STS-26 Release about the infrared intercom system they're going to try out. It would replace the RF cabin loop they currently use. The whole point: providing a "secure" communications environment inside the orbiter (RF leaks but IR won't). Oh joy! You can bet from now on only two kinds of Star Wars stuff will take place on Shuttle missions: the successes DOD chooses to trumpet, and "no news." -- Tom Neff UUCP: ...!cmcl2!phri!dasys1!tneff "None of your toys CIS: 76556,2536 MCI: TNEFF will function..."

I too read the section about using IR to communicate. My wonder is that they are making such a fuss about it. I have a copy of the DAK catalog which lists a gadget that transmits TV sound modulated on IR that allows you to watch TV in bed and not bother with long cords. This gadget costs about $100. Maybe NASA should spend more time looking up catalogs for Edmund Scientific and DAK. I doubt however that the new system was developed to secure the shuttle. They probably did not want too many stray RF sources around those comm sats. R. Anand

Rick Hauck or Pinky Nelson was just quoted either in this newsgroup or in one of the space mags (I forget which right now, I read so darn much!) confirming my suggested rationale for the IR cabin loop. They want to keep DOD missions secure. -- Tom Neff UUCP: ...!cmcl2!phri!dasys1!tneff "None of your toys CIS: 76556,2536 MCI: TNEFF will function..." GEnie: TOMNEFF BIX: t.neff (no kidding)
