Capella Space
Trying to build a SAR constellation using 3U cubesats. Interesting SAR antenna design... Which MMA is suing them over since MMA makes similar and MMA's CTO suddenly jumped to this startup after Capella having done an exploratory business arrangement with MMA which was cut off just before he left...

Expandable/deployable camper box that can slide into a cargo van bay. Though if it fills the bay, then you are only left the front seats?

Self-Deployed Space or Planetary Habitats and Extremely Large Structures
NIAC phase 1 results. NRO research related as well for deployable space telescopes. Rigidized UV cured polymer thin film bubbles for space applications. Possible flat primary mirrors/solar sails, but if they are making spheres, making curved mirror segments should be doable. If you use 6 stabilizing hoops as cut lines, can get 6 sphere segments without much waste (waste could be repurposed as additional mirror segments)

Not very specific about about how they will build the primary mirror...

Interesting deployable antenna reflector using a shape memory polymer for the reflector ribs (so sorta looks like a clam shell), and an active focus subreflector to correct and beam steer.

SPACE TELESCOPES - SpaceFab.US
Interesting design, uses what looks like deployable carbon fiber tubes (which are built up from a tape deployer style?) to extend the focal length so the small primary isn't as big of an issue (1m GSD!)

Fizeau synthetic aperture deployable telescope design for a smallsat that's kinda interesting with a Y segmented mirror which features swing out mirror wing segments.

SMAP: Specifications
Interesting that the deployable mesh antenna rotates about it's yoke continuously to create a weird spirograph-like mapping pattern.

NASA - OCCAMS: Optically Controlled and Corrected Active Meta-material Space Structures
Wow, using photonic muscles embedded in a deployable thin film mirror, using a raster scanning laser to tweak the mirror as an active optical correction primary aperture mirror by using the muscles to deform the mirror. But, the concept suspiciously looks similar to a stealth radar deflection cone for spysats patented by Teledyne Ryan and allegedly used on Misty 1/2 and NROL-15.

NASA - SpiderFab: Process for On-Orbit Construction of Kilometer-Scale Apertures
Interesting use of a 3D printer in space, but they talk abut antennas. So probably not able to do mirrors yet. Also claim radiators, which would be a neat trick.

Project Irene - IRENE Program
Umbrella methodology for a deployable high surface area heatshield. Early research way back at the start of the space age had concepts using steel meshes for the umbrella skin, with some configurations not umbrella shaped, bat rather more like a shuttlecock or fluted glass.
