Hello my Orbiter friends,
I'm working through another novel and have come across some sciences related areas that need clarification. I've been researching subject matter for some practical questions and have found myself ending up with more questions than answers. I'm hoping you guys can come through for me again,
Radio Waves. I understand that radio waves can move at the speed of light (approx 300Km/sec).
Do radio waves (electromagnetic waves), without obstruction, slow down when moving across unoccupied in space?
Are radio waves the preferred communication method between Earth and satellites or between satellites or is there another technology?
Sensors. Exploration of space has to have some degree of remote surveying capability to assess an object from a distance. I've come across these [ame="http://en.wikipedia.org/wiki/Remote_sensing"]http://en.wikipedia.org/wiki/Remote_sensing[/ame]. All of the technologies have some earth oriented use. I would like to know if these technologies are whats being used today in space exploration? If so, are they projected to be used for long term future exploration? If not, what technologies are being used?
Any direct feedback or links would be greatly helpful.
As always thank you for allowing me to use you guys as a resource.
