Post Space Networks and Deep Space Networks   Posted on: Wed Feb 20, 2008 12:37 pm
A time ago I read somewhere that NASA's Deep Space Network is aging and causing thoughts and sorrows.

What about installing a replacement in GEO, linked together and to NASA, made up of more than three antennas? There no aging by weather or effects of gravity can occurr. Protection in case of solar storms will be required instead.

What about it?

Hmm..they are constantly upgrading their network. A few weeks ago I read an article that they are currently in progress to increase capacity I think it was 5 times the current capacity.

Generally it's time to force Laser-based communications. Everyone says it's great and the future but beside in demonstrations it wasn't used yet.

There is interesting news about it in the article "Griffin: Lasers Key to NASA's Next In-Space Comm Network" ( www.space.com/businesstechnology/080929 ... tions.html )

It says that "
Quote:
If the truth be told, the Deep Space Network is 50 years old, not 50 years young, and it is showing its age," Griffin said in a speech at the 33rd International Conference on Infrared, Millimeter and Terahertz Waves.


It seems to be a project to be made reality:
Quote:
Griffin said shifting to an optical communications network will enable "exponentially higher data rates" than now are possible with NASA's current systems.

"Rather than returning grainy images like those from the first moon landing, we will be able to stream high-definition video upon our return," he said.

To help bring about this future, Griffin said NASA will develop a medium-sized optical payload and pathfinder data relay satellite, although he did not say when.


What ideas about the potntial of such a system? What about the idea to extend it over the entire solar system? There already was an experiment to receive data by laser over a distnace of a lot of million km.
