mission communications

Moving some thoughts from another section to here about communications:

Radio contact is an interesting point. I have two main thoughts on that.

The first would be a series of relays, each encased in super tough shells to allow them to survive in whatever way the ice re-froze, and released every ____ m (depending on how far you could get the signal to reach through the ice.)

The second would be a long cable, unraveled as the craft dropped further and further.

I like the relays idea better, not the least because you could build redundancy into it. (release the relays at 50% of their maximum range so that if one fails you can bypass it.) but also because they could have limited data collection on board to record the conditions in the ice.

The communication between the under-ice base and the communication satellite could be using a laser (http://www.nasa.gov/centers/goddard/news/releases/2012/12-074.html).
Homemade project where is reflected the idea (http://www.youtube.com/watch?v=HKRPfa66_po).
Under the sea like the submarine's (http://en.wikipedia.org/wiki/Communication_with_submarines) or via Underwater "wifi" (http://www.wired.com/wiredenterprise/2013/10/undersea/).
