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)

Spectrally-Resolved Synthetic Imaging Interferometer | NASA
Interesting, software combining interferometer readings digitally, rather than semi-directly via precise optical path combining. Another example of software eating the world...

PROCSIMA: Diffractionless Beamed Propulsion | NASA
Hybrid beamed propulsion rig, using favorable interactions between a neutral particle beam and a colinear laser to self focus and shepard the other.I wonder how applicable this is to conventional laser beam stuff (though the minimum beam strength probably stops anything less than a propulsion laser)

Biobot: Innovative Offloading of Astronauts | NASA
having a "rover" with a long term ECLSS pack you can jack into that follows you along, say something like a Boston Dynamics BigDog, would work alright, but then you get to the problem of what sort of bare minimum ECLSS system must exist aboard the spacesuit?

Interesting that they are OK with laser power beaming...
It's almost as if they are building a mobile SPS...

Mars Molniya Orbit Atmospheric Resource Mining | NASA
Interesting cyclic PROFAC for Mars. Using Molniya orbits is certainly different, but the main part looks to be a deep diver atmospheric scoop that spends more time out of atmosphere to cool/liquify propellant. Is this simply aerocapture by another name?

Eternal Flight as the Solution for 'X'
Use centrifugally stiffened (fabric?) rotors as a means of achieving very low weight wings. The extreme case being a kind of floppy tip driven helicopter, using solar fabric wings and electric props?

Weird jellyfish design. Something strange about it though. If it has a gravity gradient stabilized antenna pointing down, how does the reflector array operate correctly?
