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

 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.

One version of Dyson's sphere, what can be possible in the distant future

In some cases, the people think, those giant spaceships like artificial worlds, what might look like giant cylinders and the layers of those giant devices would be plantages for food and even rivers and lakes, for making the travel or being in Universe more comfortable. In some scenarios, those giant space stations would be stationed in the Lagrange-point, where the gravity of the Moon and Earth have the same strength. In that point, the large space station would stay without the need to use rocket motors, and the giant structure might be the balloon, what would look like Echo-satellites.


Inside this plastic balloon would be installed the net, and the cement, what would make possible to make plantages inside it. But there would be one thing, what could be possible. That kind of giant space station or spacecraft could operate also in the atmosphere of Earth, and the gas tank would be made by kevlar, and then there would be connected the small rocket motors. The problem would get this thing high enough, that the shuttles or the crafts own motors can transfer it to the Earth orbiter, where it would be equipped with necessary equipment.


The gas tank would be filled with hydrogen, what rises that thing in extremely high altitude. And after that, the rocket motors would push that thing to the higher trajectory. Also, the space shuttle can pull this thing to the orbiting trajectory.  If we think this thing sharp, the group of X-37B's could handle that thing, if they can be controlled as the group. This means that multiple shuttles would connect the pulling wire to the spacecraft, and then pull it to the orbiting trajectory. They might also carry remote-controlled robots, what would connect the meteorite protection in this vehicle.


Then the gas in the giant gas tank hydrogen would be changed to pressurized air, and then this cigar-looking system would be started to rotate because the temperature inside this system must be kept low, and then the gas tank would cover by gold leaf, what would make the outer layer resistant against the cosmic ray, and then the giant plastic cigar could be covered by very hard carbon fiber plates, what would also have solar panels. That system would make the electricity for that spaceship, and then the inner core would be equipped with furniture. The airlock would deny the leak of the gases, and then the spacecraft would be taken to the Lagrange point. Maybe somewhere in future, we might see that really happen.
