The Deployment

Deploying the ribbon takes innovation and care. The ribbon can not be simply thrown up into space neither can it be blindly dropped down from orbit. The deployment spacecraft is to deliver the first ribbon then climbers will build up and strengthen the ribbon to the point where it is usable.


Value Units
Spacecraft Mass 80 tons Mass of first ribbon 40 meters
Fisrt climber size 1 ton
Spacecraft propoulsion MPD
Power source MW of beamed power
Deployment time for first ribbon 2 weeks


The working climber design is File:DeploySpacecraft.aoi. Notes on the design are located File:DeploySpacecraftnotes.odt here.

Status

Large Spacecraft have been built and operated Need additional work on launching first ribbonInclude images and videos Include design write-ups

The deployment spacecraft should be largely built with conventional satellite technology.
