RIT researcher develops new solar sailing technology for NASA - RIT News
Uh, based on the vectors, this is only going to work really well for an SSO orbit riding the terminator line since you need the solar angle to be normal to the plane of the sail and keep the sail edge-on to the orbital vector...

Highly efficient and ultra-broadband graphene oxide ultrathin lenses with three-dimensional subwavelength focusing : Nature Communications : Nature Publishing Group
Sorta breaking the diffraction limit for ultrathin flat lens in a more manufacturable format, with fresnel rings being laser etched. I wonder if this would be applicable to DARPA MOIRE project, assuming you could make a large monolithic thin film of graphene.

Re-Envisioning the Telescope
Interesting way of making huge primary telescopes, using holographic sheet diffraction ratings, suitable for space telescopes. I wonder if the reverse works, shining a high power laser back out the scope to achieve a wide aperture primary.
