Transactions of the Symposium on Space Nuclear Power Systems, (5th) Held at Albuquerque, New Mexico on January 11, 1988. | National Technical Reports Library - NTIS
The PDF contains info on wheelguns, giant counterrotating flywheel hoops in space to supply power to SDI weapons, mainly railguns/particle accelerator cannons/free electron lasers that need huge amounts of power right now. Appears to expect to be trickle charged over time by a small space nuclear reactor (SNAP? atomic teakettle?). Also has an interesting microwave power beaming scenario from a nuke in mars synchronous orbit to a ground rover, high performance radiators, including a fabric heatpipe radiator, a curie point magnetic liquid droplet radiator, and other power conversion concepts.

Press Release September 18 2017 | MATT
The implication is a mars (Deimos) tether anchored off equator (13 degrees) has sufficient catenary curve to passively avoid phobos. Notably this is for a zip line down to the surface.

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?

Elon Musk's high-speed Hyperloop train makes more sense for Mars than California
Well, on mars, you could level/grade the right-of-way and lay down a sintered halfpipe, which gets you most of the way to a hyperloop configuration, since ambient atmosphere is pretty low. Use the same sucking configuration to supply air to the hoverpad feet, and exhaust to atmosphere, obviating the need for cooling exhaust air.

Helicopter Could be 'Scout' for Mars Rovers
I would have expected larger rotors, more like one of those human powered helicopters. With the low pressure, you need hugely long rotors.

I wonder if the choice of extending the time, and not have the proverbial 39 minute "timeslip" at midnight as proposed by Kim Stanley Robinson might be a better human factors choice?

Engineers creating carbon-negative Mars rocket
Basically a hybrid solid rocket, using aluminum powder grain fuel and CO2 (gas? solid?) for fuels, with the CO2 being collected locally on the martian surface. Though considering all the ISRU work done so far, I would have thought producing oxygen for the oxidizer would have been more attractive from an overall integrated system/mass/power budget perspective...
