[1908.09339] The Spaceline: a practical space elevator alternative achievable with current technology
Oddball lunar space elevator design, optimizing for upper tether length to top out at GEO height. They suggest a hybrid tether design, with constant width tape from both ends up to a certain point, then a center section that gets wider.

Analysis of a Lunar Sling Launcher
Geoffrey Landis PDF on a lunar surface sling launch system, feasibility, and performance. looks doable and can go places. If you can fire the sling towards a lunar frozen orbit (86 degrees) or similar, you could do fairly regular launches. Being a tether based sling makes it easier to pack up/deploy compared to a fixed mass driver complex. Wonder how well you could catch with one too...

WSU News Center - 3-D printer makes parts from moon rock
Using simulated regolith dust, they we able to do 3D printing. Important validation step for solar sintered moon bricks. No mention of whether they did this under simulated vacuum conditions though.

A Moon-Based Telescope - Technology Review
The bit about using reactive ion etching to finalize the lunar regolith concrete mirror shape is interesting, though is that before or after they coat the mirror with sputtered aluminum?

Kinda strange looking exhibit. Is this supposed to be the surface anchor, because it sure doesn't look like normal climbers to me? Maybe a lunar polar station anchor, since it's tilted?

Interesting concept for lunar sample return. But the architecture (EML1 centered lunar space elevator) has interesting implications for other purposes. Since it hangs "down" from L1 to earth, it's about halfway between GEO and L1. This means a notional SPS hardware delivery system that might take advantage of a two stage delivery (impulsive tug to L1, SEP tug from L1 to GEO) can be changed to not needing a SEP tug (drop off at the CW and do a small burn when approaching GEO), and possibly integrate with the impulsive stage ops. Say, burn to L1, grab and ride the tether then let go, do a light burn to place payload at GEO, then burn for aerobraking drop to LEO. This cuts deltaV down a fair bit. But, this requires a solid lunar surface anchor as you are now pulling up on the elevator every time you try to drop a load to GEO. I suppose you plant the anchor for the balanced cable, then use bulldozers to keep loading regolith on top of the anchor to weigh it down.

Developers Say Lunar Elevator Could be Built Within a Decade | Universe Today
I like this idea. It gets a lot of the hard engineering out of the way using COTS or materials/equipment that is available now, and gains both a possible revenue stream and operational experience (for both earth based space elevators, as well as rotovators and skyhooks). Single launch on an existing rocket means this isn't a project that is married to some unicorn HLV. This would be an interesting place for google to dump some money...

New version of the old lunar rover tires for much higher loads and longevity. Potential earthbound applications as well (possible competitor to the Tweel?)

Moon Mine
Attempt at trying to do something similar to the Mars Society and their Mars Outpost science stations; try to replicate, within reason, a moon ISRU mining colony to work out the kinks.
