| NASA says Maxar will build first big piece for Gateway in lunar GeekWire |
I have noticed that things are moving in this direction which is becoming somewhat secretive like many other major scientific discoveries. We must consider the advice of the most enlightened mind in the last decade of science, and that can only be Stephen Hawking, who said to hasten the colonization of other planets because a catastrophe can destroy the earth at any time. Stephen didn't even think that a virus could be the cause you can read below and let's get back to the main topic
A spacecraft launched from a massive Magnetic Levitation Accelerator located on the moon could reach relatively high relativistic speeds at this stage, which no other means of propulsion can do practically and start from the great Hawking project and many other space science projects we can succeed.

If such a ship without a human crew had a compact nuclear fusion reactor, say in a few decades, then humanity could have spacecraft that could reach Alpha Centauri and a few other nearby star systems with planets like Proxima b one of the nearest planets the closest planet outside the Solar System, "A telluric exoplanet, which is in the habitable zone of the star Proxima Centauri.in just a few years. decades".

The faint red star in the center of the red circle, at right angles to both and south-east of Alpha is Proxima Centauri, intensely red, smaller in size, weaker in brightness and a distant third element in a triple star system with the main close pair forming Alpha Centauri.

People could withstand huge accelerations using liquid and gel capsules for compensation or even a rotating sector of the ship that by centrifugal force would compensate for the ship's acceleration. Such a hybrid ship would also have a magnetic parachute that would activate when meeting the Alpha Centauri heliopause.

I don't know, but let's look at some numbers ... speed of light: 300,000 (3 hundred thousand) km/second!!! alpha Centauri: 4.3 light-years ... if 10% of the speed of light could be obtained, ie 30 thousand km / s, then the journey would take 43 years ... ok ... the fastest thing launched by man, voyager 1, travels at 17.26 km / s ... so we should, in exact numbers, get from 17.26 to 29979 km / s, that is 1736 times faster than mankind has managed so far, to reach +4 decades! You have low gravity per month, but how much are the acceleration increase and the braking problem?

The system would be feasible for launching anything into orbit without any rocket systems. The moon has an orbital speed of 1022m / s so very low, with a rifle you can shoot a bullet at a higher speed. It would have the advantage that it does not require rocket fuel or expensive rocket engines and you can launch large loads. To reach 1100m / s with an acceleration of 1g, 60km is enough.
Since even people can bear 2-3 G FORCE without big problems, a perfectly achievable 30 and 20 km launch ramp would be enough but of course, ramps or even hundreds of km can be built to reach the desired speeds, regardless of costs considering that it is about the survival of the human species that is self-destructing since 1900. Future galactic colonization ships are the launchpad to Mars and many other planets and solar systems like Alpha Centauri. You can't leave the earth with a ship big enough to carry everything you need, but you can get off the moon.

You can make it from pieces that connect like this international station that was also made of pieces launched one by one, only that from the moon you can launch much larger pieces. Until we have a monthly station, I don't think we'll reach Mars with a human crew at least not very soon.
The centrifugal force would be very high at the speeds required only for launching into orbit and it would be extremely difficult to make this ring. It would not have special advantages over a linear accelerator that is much easier to achieve technically.
It cannot move in a circle, the centrifugal force becomes excessive. Even at a modest, strong, and enormous speed. Let's take a ring with a radius of 10km and an object that goes with 1km / sec so the monthly orbital speed which is very low compared to the cosmic speeds. The centrifugal force will be equal to 100x the mass of the object. And the objects inside the supposed ship will suffer the same force, it's as if they are exposed to 100g so you can't have passengers in the ship even at this modest speed because people can't tolerate more than 5-6g and that for a long time. Besides, the ring should be very strong to withstand such forces.
Magnetic levitation should withstand this force so it should in turn be very high totally unlikely to be achieved practically. There are fantasies that some launch but they don't think (and they haven't been to school either). To have the only 5g on a 10km ring, the speed range would be only 223m / s. To reach the launch speed on the moon with only 5g centrifugal force would require a ring with a radius of 200km. It is much easier to make a linear accelerator.
All these physio-fusion-nuclear (see, you can do in 3 words.. we have a weak point. We do not know how to produce energy other than through thermal energy with thermal machines that require a hot and a cold source. The hot source is the fissile material but the cold source in space does not exist, the energy can be dissipated only by radiation which is very inefficient compared to cooling by conduction to another substance (air/water). This drastically limits us to the power we can get from a space reactor. At least until we find another way to produce electricity to power various other motors we can not hope for too much power in space.
