Don't know where to put this but I think it should also be investigated using self-assembly in space to get large spacecraft.

The problem is small craft have a good area to volume ratio, and with volume as a proxy for mass, a good area to mass ratio. This is important for getting a high acceleration due to light pressure.

However, one way to maintain the high area to volume(mass) ratio for a large craft would to keep the large craft very thin, just as thin as the small craft. The large mass is obtained by area dimension large.

Answer:

Something like this may be possible. We are looking into many options for building and protecting the electronics.

Answer:
You’re totally right about needing to keep the area to mass ratio very high. However, there are some other considerations when thinking about making the craft very large and thin. For example, material strength and structural stiffness.
