What is causing the delay in the launch of James Webb Space Telescope?

Update: 12 April 2020


The Hubble Space Telescope has been a significant contributor to everything we know about this universe. It is one of the biggest technology of humans till now. It has given us the answers to many questions but still, we have some questions which it is not able to answer.

NASA has teamed up with European Space Agency to create a better telescope. The name of this advanced telescope is James Webb Space Telescope.


What advanced technology is used in the James Webb Space Telescope?


James Webb Space Telescope is larger in size than the Hubble Space Telescope, Hubble's primary mirror size is 2.4 meters, while the James Webb Space Telescope's primary mirror size is 6.5 meters, which is much larger


What is causing the delay in launch of James Webb Space Telescope

The James Webb Telescope is designed to be repaired once launched, which is why it is designed to capture a different type of light. The James Webb Space Telescope is designed to capture infrared light. Has been made which means it will be a very cold telescope which will have to work in the temperature of -230 ° C.

Hot objects emit infrared radiation. As much as the telescope's infrared sensitivity would be good, it would have to be kept cool in every storm, or else it would be so bright in front of its own heat radiation that it would not see anything

The cryogenic will be used to keep the detector of the James Webb Space Telescope cool, one of its features will be that through this, we will be able to see the past of the universe far beyond what has not been possible so far, that is also the answer with the help of light.

We know that this universe is spreading, the galaxy is moving away from each other, due to this, the light of the old galaxy is very faintly converted to infrared, due to which it cannot be seen in a simple way, but the infrared detector makes it easy Can detect

James Webb will be able to direct infrared light because of this we will be able to see old stars or Galaxy. We will be able to see the 100 million-year-old universe with the help of James Webb, to make it work in a cold environment.

Sunshield has also been added to it so that it can be protected from the rays of the sun, 5 layers of shields have been added to it, keeping it cool will also protect it from space debris.
The James Webb Space Telescope will be placed outside the Earth's orbit, 1.5 million kilometers from the Earth's orbit. Keep it cool

What are the disadvantages of the James Webb Space Telescope?


Where infrared detector has some advantages, it also has some disadvantages.
Light has two nature
Particles-They can behave like particles and they can be broken by colliding with dust particles.
wave-Like wave, we can also have deflection from the edge of a telescope which we call diffraction.

In such a situation, it will be difficult to focus on the light, which will be seen as an object or star blurred, how clear is the picture taken with the telescope, it will be completely fixed at the diffraction limit which increases with the increase of the wavelength.

Compared to Visible or Ultra Violet Space Telescope, this is a bigger problem in the Infrared Space Telescope. If the aperture size is high then the diffraction limit is reduced.


When will the James Webb Space Telescope launch?


James Webb was supposed to be launched in 2018, but due to the mission being very costly, it has to be launched successfully at one time, with its sunshield was obstructed in the opening, this mission was delayed. Now this mission 30 Will be march 2021

Launch date: 30 March 2021

Cost: 1,000 crores USD

Launch mass: 6,500 Kg

Power: 2000 watt

Contractor: Arianespace

Mission duration: 5 Years (design); 10 years(goal)

Manufactures: Northrop Grumman, Ball Aerospace & Technologies
