While the Moon is accessible to us with current technology… the rest of the solar system… including Mars… will require breakthrough technology to colonize in a reasonable time frame. The technology now exists to expand humanity even beyond Mars… to the hundreds of other worlds throughout the solar system.

Would it be possible to cut the 8 month Mars travel to 4 via use of solar sails with ion engine to supplement constant thrust?
Imagine a solar sale based orbital booster system that would reach ridiculous speed over the course of several orbits then fire out a line that is caught by a departing star ship that slowly gets reeled in as it bleeds off acelleration from the orbital craft. That starship then slingshots or even gets towed by the orbitaal booster as it or they move toward Earth.
Its function would be somewhat analogous to the hyperdrive fixture that is mounted onto the X Wing in Star Wars.
I imagine it being able to bring Star Ship up to 3% of light speed by use of solar power but those sails qould need to be tremendous and a lot of orbits will be needed, to the point where no tethering system can really work at the level of speed required to make the system cost effective and snagging the star ship before all pertinent critical thresholds are met would still leave the crew waiting a few orbits before the solar sail system can significantly shorten the time elapsed in transition to Earth… if it is only a few days in orbit before total transportation time is reduced to a month then it should be worth it. I am not smart but someone has to be smart enough to figure out how something similar could work…
A solar sail highway supplemented with chemical engines might be the most cost effective way to colonize the inner solar system.
Utterly foolish trying to create practical fusion power when a huge long lived fusion power source is 8 light minutes away.
okay, okay. An ad has shown up. An ad about poop poop. What to do? Take out the ear buds and let the ad play while I pick up a book to read. That way the ad folks ( I hope) will have to pay for the ad. Ha, ha, ha. Read a valuable book while the ad grinds on. Here goes.
If it's not been suggested before, you should do a segment on Nuclear Salt-Water engines (re Scott Manley) – a whole lot simpler a rocket to get us anywhere at 1G.
I personally think that the most viable solution for interplanetary travel in a regular way by a interplanetary civilization is through magnetic mass accelerators, either in a planet or moon without an atmosphere or in orbit, transfering momentum from the accelerator to the ship and thus reducing its velocity and then recuperating that velocity by "catching" arriving ships transfering their momentum to itself. Every propellant based solutions is ultimately unsustainable, since it's not renewable. Yes it's small amounts of propellant we are taking from the atmosphere and spreading through the solar system, but we also thought that with fossil fuels… If we travel enough we can end up with no gases in the atmosphere to use as propellant
Titan is smaller than Earth but larger than our moon 2:45
Thanks for yet another great and educational video.
