Staging from LLO reduces lander DV to about 1.8km/s one way but SLS an Orion can't support LLO operations.

Over the next few months there are going to various official design reviews of the lunar landers. Hopefully these will produce some interesting pictures, power points and statistics.

Preferably commercial, as that's far cheaper.

Preferably commercial, as that's far cheaper.Plus a CRS or CC COTS like program can result in multiple providers competing for the anchor tenant NASA and other follow-on commercial/scientific customers. As with CC and CRS, NASA was able to get multiple providers developed through PPP for cheaper than for a single NASA government driven sole sourced design procurement.
