Ganymede is one of the best places in the solar system for a space colony. There's plenty of water there and it's the only rocky body outside of earth, with a magnetosphere, to help shield from radiation. Not to mention that you would have an awesome view of Jupiter in the night sky, which would be absolutely stunning. It's also one of the largest moons, so gravity wouldn't be as bad as it could be on one of the smaller moons. It's in the middle of the solar system too, which could some day help provide a launch point for exploration of the outer solar system as well.

We currently use tunneling machines, here on Earth, that as they dig, they take the excavated material and turn it into wall panels and install them as the machine moves forward. Why not deploy such a system on Mars, or even the Moon.

Not mentioned in the video, is spalling, which are flakes of material that spray outwards from an interior surface when the exterior surface is impacted. High energy particles are small, but they have a lot of kinetic energy. If those particles don't penetrate your spacecraft, don't just assume that you are safe.

It's amazing to me that the smallest atom, Hydrogen, is a good candidate for radiation shielding when the most common radiation shielding down here on earth is lead. I've heard of water-lined spacecraft proposed, but hadn't heard of the hydrogenated nanotubes. Fascinating! I suppose the key is to have the hydrogen tied up in a molecule in liquid (molecular water), or solid form (lattice, or tube form) as opposed to gaseous form where the atoms are spread far apart. I wonder if cryogenic hydrocarbon rocket fuel would have a dense enough hydrogen concentration to work.

The images of robots building structures on Mars! That was super cool, thanks for including those.

Gravity (or lack of it) is also a major problem for space exploration. Just my opinion, but in the near term we should use teams of robots to work on both the moon and Mars. Let them construct habitats and other structures. Then have humans move in. Robots don't care about food, water, radiation or gravity.

The fear of low-level radiation is mostly superstition. The levels of radiation on the Martian surface may cause cancer or leukemia in 40 or 50 years, but the chances of the first Martian colonists living that long are really pretty slim. If we have learned anything from history, we know that the first colony will almost certainly be wiped out by some accident. However, we also know that we can protect people simply by piling dirt over the colony. There are likely other ways to do it as well that will be thought-of in due course. So, radiation isn't a real danger.

Thanks. Excellent presentation!

Radiation is an important concern, yes, but then *everything* about space travel and visiting other planets is an important concern. Food, water, energy, gravity, boredom, etc. The distance to Mars is a lot greater than the distance to the moon, and they'll still need to carry all the food and water the astronauts need to survive the trip and back, not to mention the energy they'll need to travel there and back.

With over 19 years' experience occupying the ISS and the new heavy lift rockets coming out, the food and water and life support gases are the "easy" part of such a trip. We can do that. We've kept individuals in space for many months at a time. We can easily assemble-in-space a large enough ship to get to Mars and back. We can pre-stage a lot of supplies on Mars' surface in advance at the intended landing site so the crew doesn't have to carry it all with them. These are all "stretch challenges" with existing technology, but quite doable. The much bigger problem, by far, is the radiation-in-transit problem. And I think a big part of the solution is to make fortified, hardened sleeping spaces that can be retreated to during solar activity -- much easier than fortifying the entire crew module. Gotta stay in your bunk rack for a few days? Equip the bunk racks for mild to medium sedation to ease the cramped-up times. After you solve for radiation, turn your attention to non-gravity. So far, wayyyyyyy underdeveloped is any kind of spun structures capable of providing gravity needed for such a long trip. Do we need a full 1 G? Doubt it! Even 1/2 G is better than no G.

I think it will be essential for long space journeys, such as a trip to Mars. It shouldn't be too difficult either. All you need is tethered units. Ideally, you'd want a minimum of three. That way, docking and undocking can take place in the central unit while the whole thing is still rotating - no need to stop the rotation at any time. It could remain as an orbiter while a landing vessel makes the trip to and from the surface.

Artificial gravity has a number of very huge barriers, and the physics of it is not even viable from a theoretical standpoint yet. The physics of Gravity as a force is very isolated from the other fundamental forces of classical physics, and so in order to crack artificial gravity, you would have to generate a grand unified field theory that links gravitation to the other fundamental forces that we have already mastered. Once that is figured out, now you can proceed to design devices that can manipulate the gravitational field and can either amplify it or attenuate it at will and in a controlled and predictable manner. And furthermore, a device that can make use of the other forces which we already know how to operate such as electromagnetics in order to generate a gravitational field of a definite strength and a defined sphere of influence. Only then can artificial gravity become a reality. It may take several Einstein-level geniuses to crack all this.

Distance. It is is just extraordinarily overwhelming. I mean for trips outside our own solar system. I always found the idea of colonizing planets on other systems inspiring, until I realized that unless we find a way to literally teleport across the universe, there is no point in colonizing. Lets take the closest earth like planet we know of so far. Scientists say that it is 40 light years away. That means that if we had established a colony on that planet, even if we could send messages at the speed of light between earth and that colony, it would still take 40 years to ask something and another 40 to get an answer!! That makes these two societies virtually unrelated and I find that thought quite sad...

If I'm wrong and low-G turns out to be bad, it's still not a big problem, just - everyone on Mars has to live on a giant, underground tilt-a-whirl. (Underground because of radiation.) Radiation and perchlorates and even gravity are easy problems to solve. Extracting water from the ground to make fuel and oxygen should be ~easy. So should growing food. Most of it seems "easy."

I think that colonizing Mars will be very difficult. Since the atmosphere is almost gone the ground and soil is highly radioactive too, meaning the layers of ground / dirt they’d use as protection on the colonies is still radioactive.

In the Star Trek series, they used invisible shielding to surround the ship, which makes sense. Also the doctors would give some anti-radiation injections if they were exposed too long outside. Maybe S/F to us now, but gives the geeks something to work on. Our early cell phones were nearly exact copies of the communicator they used, down to the flip up top. 3d printing was culled from them too...just imagine having a food replicator and dialing up whatever you wanted to eat in seconds.

That was an issue twenty years ago due to ozone depletion (different to climate change), but as humanity has stopped using certain polluting chemicals, the ozone has begun to repair itself.

It’s a pipe dream. Nobody can think of any practical or economic benefit from such a difficult and colossally expensive operation. If a magnetic field can deflect Uranium nuclei at the speed of light, a nuclear reactor could be flown to power it, and it would be needed to have any possibility of powering the building activities shown. Although pointless, it would make more sense to colonise the dry valleys in Antarctica instead.

Or if civilization doesn't collapse into chaos in the mean time. Space exploration would be a much lower priority when there are more urgent problems to solve on our own planet that need money, time, effort and ingenuity.

I'm perplexed by a certain scenario and need clarification. If a detector detects an event of these harmful particles and it's traveling close to the speed of light how would the detector be able to warn the occupants of the craft since the signal to warn and the event would both be traveling at the speed of light. I.e. how would they be able to relay the signal faster to warn?
