Quote from: Melt Run on 11/10/2013 01:16 pmThe next laser comm system LCRD will have a data rate of 1.22 Gb/s (coded) and 2.88 Gb/s uncoded. It is scheduled to launch in 2017.This is awesome tech. Are there any plans to fly an experiment like that out to interplanetary distances yet ? Having a data rate like that from a martian data relay orbiter would be amazing, even if its not the primary data link.

Of course the further you go the more challenging things get. Especially when looking close to the sun.
Is there any likelihood such a payload could get onto the 'Curiosity 2' rover?

In fact, if EDRS is based on LCT, I doubt GEO<->LEO is less complicated than MMO<->Mars surface. Keeping the optics clean might be a challenge, but if you can do 100Mbps bursts you'd only need short communication windows and use a store and forward architecture.Of course no current or planned Mars orbiter will carry LCT capability, so it's sort of a moot point.
