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?

PHARO paper showing a diffuser collector inlet, much like more conventional ramjets, is better for hypersonic reasons.

Wow, Sterge Demetriades really got shafted for his work on PROFAC. I wonder what those other 3 ARS/AIAA papers look like? FOIA request to declassify them perhaps? Lots of other interesting tidbits in this PDF. Using the LOXLEO collector materials concept as a capture liner on a more conventional PROFAC cone nozzle input for the MHD ramjet might be the trick to doing this right.

Harvesting LOX in LEO.pdf (application/pdf Object)
Patented by Paul Klinkman? Claims of a patent application with 34 claims, but nothing showing up in google patents though. Electrodynamic tether boosted collector, 50Km tether needs 60N thrust mounted trailing up only, 325km collector altitude, 30m mouth. Focused on oxygen collection though (altitude where oxygen is about 85% dominant).

Scooping atmospheric air (PROFAC revisited)
Hrm, PHARO variant resembling a ramscoop connected to a solar array kite joined together via an electrodynamic tether, to possibly eliminate the MHD ramjet for propulsion and increase solar array size? It would also keep the large solar array out of the high drag regime. You could even go for an inflatable solar array. Though vehicle dynamics gets ugly, and now you are dragging around two and half objects through crowded airspace.

PHARO is the electric version of the PROFAC ramscoop atmospheric propellant collector/diver, using concentrated reflected light from SPS' dumping on a passive cooled solar cell array at (?5x-50x?) solar intensity for roughly 175KW to power an MHD ramjet thruster running on collected liquid air/nitrogen. Quick and sleazy mods I can think of are using ground based laser beamed power (rather than simple SPS reflected concentrated solar), inflatable frustum collector nozzle expansion, and perhaps a VASIMR engine (though the MHD ramjet in principle is similar to a VASIMR, with fuel coming live from the collector).

Rocket science :: PROFAC
PROFAC is the nuclear thermal atmospheric propellant ramdiver, PHARO is the electric MHD engine version (ostensibly powered by 5x concentrated solar power beamed from an SPS constellation). It actually makes sense, especially if you have an offboard power source (PHARO was looking at a 200KW range power receiver). Easy mod is an inflatable frustum over the collector cone to increase the size of the of the capture inlet.

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.
