Webb Telescope launch delay: will become the most powerful exploration tool to date

Many scientists believe that there is another planet similar to Earth somewhere in the universe, and the search for it is about to begin. The launch of the James Webb Space Telescope (JWST), which was postponed until March 2021, will be more than its predecessor. Powerful, and able to detect farther universes and discover planets in distant galaxies. It can even provide us with tools to find traces of the atmosphere that sustain life.

Although there are larger telescopes on the ground, as its name implies, the James Webb Space Telescope will roam over the atmosphere, providing a much more cosmic vision than the famous Hubble Space Telescope. The Webb Space Telescope is powered by American space. The Bureau, the European Space Agency and the Canadian Space Agency, jointly invested in a capacity of 6 tons and will operate in an orbit about 1.5 million kilometers from the Earth. The Webb Space Telescope is equipped with many of the latest technologies, such as an expandable Sun visor and a foldable segmented mirror.

Why is the James Webb Space Telescope so respected? There are several reasons:

1, it is very powerful. It will be the largest and most powerful space telescope ever sent to space by humans. There are larger telescopes on the ground, but far less complicated than space telescopes. Obviously it will be the most powerful space. The Webb Space Telescope is the successor to the Hubble Space Telescope, but it is a hundred times more powerful than Hubble. According to the project website, the Webb Space Telescope has a larger mirror than the Hubble Space Telescope. The larger lighting area means Weber Space. The telescope can surpass the Hubble Space Telescope to explore the more distant universe. Hubble's orbit is closer to Earth, and the Weber Space Telescope is 1.5 million kilometers from Earth.

2, It can be said to be a time machine. The Hubble Space Telescope can see the galaxies of the adolescents of the universe, and we want to see the cosmic galaxies of the baby. With the Webb Space Telescope, we will be able to trace the earliest in the universe for the first time. Objects. For the first time, we are able to explore other planets in other orbits and distant alien planets, and to know if there are oceans, atmospheres and chemical elements.

3, It will help us draw a map of the universe. The Webb Space Telescope can't decisively judge whether there is a life on a planet, but can start to depict the universe and judge whether there may be a sea there, so that we can provide us with a further exploration of the universe. Roadmap. The Weber Space Telescope will use the infrared to observe the universe. This is very important because the newly formed stars and planets are hidden behind the dust, and the dust absorbs the visible light, but the infrared rays can penetrate the dust.

4. It may help us discover another planet. We plan to explore the nature of the dark energy of the universe and understand the characteristics of the ancient monsters in the universe. Depicting the characteristics of the planets around other stars allows us to find out if there is another in the universe. An Earth. The Webb Space Telescope will also help us find alien planets. In fact, looking for alien planets is an unplanned job of the Hubble Space Telescope.

5, it represents a technological subversion. It is possible to completely rewrite our textbooks, because it will significantly increase our understanding of the universe. We will be able to better grasp the universe we live in. From a technical perspective, we Just seeing the impact it has.

Northrop Grumman, which mirrors the Webb Space Telescope, must make a breakthrough because the mirror of this precision has never been created.

With a main mirror diameter of 6.5 meters, the Webb Space Telescope has a seven-fold increase in daylighting compared to current space telescopes. The Webb Space Telescope will have a larger viewing angle than the Hubble Space Telescope, and with the Spitzer Infrared Space Telescope. Compared to having better spatial resolution.

The James Webb Space Telescope is scheduled to launch in October 2018, but NASA has delayed launch times several times and claimed that it will take more time to integrate and test components. According to NASA, when Weber When the space telescope finally can be launched, it will take off from French Guiana on an Ariane 5 launch vehicle.
