Thank you!

Exactly

I read somewhere about having a theory to deploy a space craft that was in a orbit that would bring it close to mars and earth on semi regular intivals. With the idea being the craft is a giant hard drive. You upload via laser when its close and downoald on the other end. It does not provide real time comms but instead bulk data transfer capabilities.

I tried googling looking for a ref quickly but could not find it sorry.
