The James Webb telescope is on its way to L-2 point.

There was a little mistake in my text yesterday. The James Webb Space Telescope is on its way to Sun-Earth Lagrange point L-2, not L-1. The JWST is the new and the most powerful instrument that astronomers ever get in use. And the thing is that this instrument is acting as a pathfinder to other, more powerful telescopes that are sent outside the Jupiter trajectory.
Maybe someday the NASA and European Space Agencies are accomplishing the TAU mission. TAU (Thousand Astronomical Unit)is the space telescope that will be sent away from the solar system, and that telescope will base similar technology with the JWST. But those things are the future views of deep space missions. The truth is that the JWST can reach outer planets as well as another solar system by using excellent accuracy.

The 6,5 meters infrared telescope of the JWST telescope makes it far more accurate than the "Spitzer" telescope, which mirror is 0,85 meters. Spitzer was a great success and that telescope was deactivated in January 2020. But the 6,5 meters infrared telescope would see more than some 0,85 meters telescope. That means the new era of space research is beginning.
In the future, the Lagrange points around the Sun. Are useful in many more missions. One of the projects could be sending the laser satellites to those points. Those satellites can observe gravitational waves by using more high accuracy than LIGO ever can use. Lagrange points or "L"-points gravitation is interacting with objects. The way that they are hovering in those points without the need to use the power. The L-points can benefit in positioning the large-size space stations.

The O'Neill cylinder
And that thing can make them useful in the location of things like "O'Neill" cylinders. The thing is that those artificial worlds must not have similar gravitation with Earth. The "O'Neill cylinders" create gravitation by using rotating movement.
Sometimes is mentioned that O'Neill cylinders are impossible. The rotating movement would cause centripetal force that rips the station in pieces. The gravitation field of the Earth is so strong. That the speed needed for rotating the station is very high.
The purpose of gravitation in those systems is to anchor things like vegetable cultures to the surface. Not create similar gravitation with Earth. But there is possible to put powerful magnets to the center of the cylinder. That magnetic stick pulls the structures of that kind of station in the middle. And the magnetic pulling effect will counteract against centripetal force. The magnets would pull the structures inside. And that keeps the wall of the cylinder in one piece.
