I believe that one of the major factors in the survival of the human race is the migration of our species off-planet, into space.
One aspect of our expansion beyond Earth is the ability to communicate and access the information infrastructure that we call The Internet.
The interconnected electronic hive mind, made of signals and data storage, has become an integral part of the human experience. Space colonists or long-term travelers will need ways to stay connected to whatever digital information network humanity is using.
I saw this article about NASA's plans to create a laser broadband that can be used to transmit data in the immediate area of the solar system.
As for data storage moving into space, we are already beginning to send artifacts of humanity to the moon.
Any where humans go, we will also take physical objects with us, so it's good to think about how to create things that can withstand environmental extremes.
Ultimately, I think we will have to develop some form of communication similar to the "FTL (Faster Than Light) communication" in the game series Mass Effect. If not through the use of advanced space/time relays, than perhaps through quantum entanglement or some yet undiscovered technology...
