asteroza + glider   33

Media - News - UK team trials new ultra-endurance air vehicle - University of the Highlands and Islands
Similar to Slocum gliders, but use buoyancy in air. But considering the medium, won't you need bigger wings? I seem to remember a passenger craft concept that was similar, with a catamaran body, a large wing, and a centered over-wing engine cluster, called GravityPlane.

Rocket recycling – catching rocket stages after launch
Huh, catching a winged first stage booster rocket by the nose, air towing to a landing site, then releasing it again so it can glide to land. Avoids boost-back for recovery (more fuel for main flight), doesn't require a landing site forward in the ground track for the booster either. Catch-and-release, like a big mouth billy bass...

Multi-day solar drone. Wonder if this has thermal updraft flight capability to augment endurance?

Wave Foil Developments
Basically wave glider parts mounted on the bow of a commercial ship. Sure, it probably works at reducing drag/increasing performance, but how would you deal with the draft increase? Retractable foil?

Crazy dude want to surf stratospheric mountain pressure waves and the polar vortex to fling his pressurized glider to over 90,000 feet! Which just so happens to be similar to Mars, so any research results may be applicable to NASA martian aerial exploration...

Liquid Robotics —
Different from those submarine slocum gliders (AKA Iron Albatrosses), this one uses an underwater wing to rectify wave motion to provide propulsion.
