In this article, we are going to answer some common questions about this telescope  , The answers to these questions have been collected from reference and reliable sites So stay with us to find out about these exciting questions

What is the status of the Webb telescope?

Webb is currently at its observing spot, Lagrange point 2 (L2), nearly 1 million miles (1.6 million km). It is the largest and most powerful space telescope ever launched.

 

Who is James Webb and what did he do?

Webb ran the fledgling space agency from February 1961 to October 1968. He believed that NASA had to strike a balance between human space flight and science. The man whose name NASA has chosen to bestow upon the successor to the Hubble Space Telescope is most commonly linked to the Apollo moon program, not to science.

 

Where is James Webb right now?

Earth-Sun Lagrange point

JWST is now orbiting around an invisible point in space known as an Earth-Sun Lagrange point. It's a somewhat mystical area of space where the gravity and centripetal forces of the Sun and the Earth are just right, allowing objects to remain in a relatively “stable” position.

 

Who designed the James Webb Space Telescope?

 

Northrop Grumman leads the industry team for NASA's James Webb Space Telescope (JWST), the largest, most complex and powerful space telescope ever built. The Webb Telescope will fundamentally alter our understanding of the universe.

 

What is the difference between the Hubble telescope and the James Webb Space Telescope?

 

Furthermore, Webb has the ability to, and is designed to primary detect infrared light, leading to unique and stunning images. Hubble, on the other hand, can observe light at optical and ultraviolet wavelengths. While the Webb telescope is about a million miles away, the Hubble is roughly 340 miles.

 

What is the main purpose of the James Webb telescope?

 

The James Webb Space Telescope is an infrared observatory orbiting the Sun about 1 million miles from Earth to find the first galaxies that formed in the early universe and to see stars forming planetary systems.

 

How much does James Webb telescope cost?

While the $10 billion price sounds inordinately high — and it is — the JWST is the world's largest and most powerful science telescope in space. It's expected to help researchers unearth everything from mysteries of the Big Bang to alien planet formation.

 

How fast is the Webb telescope moving?

 

The observatory was traveling at much higher speeds earlier in its trip, when it covered most of the distance. After separating from its launch vehicle, JWST began to slow rapidly and it is now traveling at a cruising speed of around 0.2 miles per second towards L2, or roughly 720 miles per hour.

 

How far can the Webb telescope see?

How far back will Webb see? Webb will be able to see what the universe looked like around a quarter of a billion years (possibly back to 100 million years) after the Big Bang, when the first stars and galaxies started to form.

 

How long did it take to build the Webb telescope?

The James Webb Space Telescope (JWST) has taken 30 years and $10bn (£7.5bn) to develop, and is being described as one of the grand scientific endeavours of the 21st Century.

 

How many countries are involved in the James Webb Space Telescope?

14 countries

James Webb. Space Telescope

Thousands of scientists, engineers, and technicians from 14 countries, 29 U.S. states, and Washington, D.C. contributed to design, build, test, integrate, launch, and operate Webb.

 

Where will the James Webb telescope be in space?

The James Webb Space Telescope reached its final destination: L2, the second sun-Earth Lagrange point, which it will orbit, on Jan, 24. 2022 after traveling nearly a million miles (1.5 million kilometers). Lagrange points are gravitationally stable points in space.

 

How many mirrors does Webb have?

18

While some of the largest ground-based telescopes on Earth use segmented primary mirrors, Webb is the first telescope in space to use such a design. The 21-foot, 4-inch (6.5-meter) primary mirror – much too big to fit inside a rocket fairing – is made up of 18 hexagonal, beryllium mirror segments.

 

What fuel does JWST use?

hydrazine fuel

Developed by the European Space Agency (ESA), the heavy-lift space launch vehicle was used to propel the telescope into outer space. Prior to launch, the telescope was fueled with 240 liters of hydrazine fuel and dinitrogen tetroxide oxidizer.

 

Can Webb be serviced?

There is currently no servicing capability that can be used for missions orbiting L2, and therefore the Webb mission design does not rely upon a servicing option.
