Laser communications may result in live HD video from Mars

Another revolution could take place in interplanetary probe SIZE since
the transmission power needed for high data rate communications is
irrespective of size. This means that a small spacecraft with
correspondingly small solar panels simply would not be able to generate
the power needed for high speed data transmission. If laser based
communication terminals are used we might see dimunitive-sized
spacecraft send to Mars with a huge cost savings since laser
transmission uses comparatively little power.

I'm really looking forward to seeing live full HD video from a Mars
probe or even Jupiter!
