The much malicious mission was intended to replace the long-running Hubble telescope, but is troubled by problems and delays.

Named after NASA's second administrator, the replacement flagship telescope has also raised $ 800 million from its huge $ 8 billion budget.

It is designed to study the origin of the first stars of the universe and their dim light, but torn sunshades and loose bolts have previously been blamed for the setbacks.

It was first reserved for a launch in October 2018 and is now scheduled for its virgin journey in March 2021.

Jim Brindenstine, NASA administrator, said in a tweet: & # 39; or the first time ever, the spacecraft and telescope have been merged into one observatory.

& # 39; After further integration, @NASAWebb will undergo testing before being sent for launch. & # 39;

It is hoped that the James Webb telescope will be able to stare at the atmosphere of distant exoplanets that are still being discovered.

NASA has announced that its engineers have for the first time connected the two separate halves of the telescope at the Northrop Grumman facilities in Redondo Beach, California.

As soon as it reaches space, NASA's most powerful and complex space telescope will explore the cosmos using infrared light, from planets and moons in our solar system to the oldest and most distant galaxies.

James Webb Space Telescope (JWST) is a joint venture between NASA, ESA and the Canadian agency CSA.

The gigantic assembly puzzle saw engineers lift the Webb telescope – complete with mirrors and delicate instruments – above the awning and spacecraft.

A crane did the heavy work, while a small army of staff scrambled around to make sure nothing was damaged and the two halves were placed and connected correctly.

Mechanical connection is now followed by the complicated process of electrical connection between the two sections.

& # 39; The assembly of the telescope and its scientific instruments, awning and spacecraft in one observatory represents an incredible performance of the entire Webb team & # 39 ;, said Bill Ochs, Webb project manager for NASA Goddard Space Flight Center in Greenbelt, Maryland.

& # 39; This milestone symbolizes the efforts of thousands of dedicated individuals for more than 20 years at NASA, the European Space Agency, the Canadian Space Agency, Northrop Grumman and the rest of our industrial and academic partners. & # 39;

WHAT IS THE JAMES WEBB TELESCOPE?

The James Webb telescope has been described as a & # 39; time machine & # 39; it can help to unravel the secrets of our universe.

The telescope will be used to look back at the first galaxies born more than 13.5 billion years ago in the early universe, and to observe the sources of stars, exoplanets and even the moons and planets of our solar system.

The huge telescope, which has already cost more than $ 7 billion (£ 5 billion), is considered a successor to the revolving Hubble Space Telescope

The James Webb telescope and most of its instruments have an operating temperature of about 40 Kelvin – about minus 387 Fahrenheit (minus 233 Celsius).

Officials say the costs can be higher than the $ 8 billion (£ 5.6 billion) program cap that Congress has set. The space agency has already deposited $ 7 billion (£ 5 billion) in the telescope.

When launched in 2020, it will be the largest and most powerful telescope in the world, capable of looking back 200 million years after the big bang.

In January, the telescope was successfully tested in a giant vacuum chamber at the Johnson Space Center – which proved that it will work in the deep space.

The telescope has tested cryogenically for 100 days, with the temperature falling hundreds of degrees below freezing to ensure that it functions in extreme cold.

It will soon be rolled out and fully tested to ensure that it can adequately protect the instruments against the infrared radiation in the room.

The American space agency wants to launch James Webb soon, but is already looking forward to the future and a life after JWST.

Last year it chose a team of expert astronomers to choose the eventual successor that will be built and sent into space in the 2030s.

Four hugely different designs have been put forward designed to search for extraterrestrial life, distant earthy worlds, black holes and the birth of new galaxies and energy-rich gas discs.

All four proposed missions look very different and the memorable decision is likely to affect NASA & # 39; s research in the coming decades.

LUVOIR will continue a mission similar to that covered by Hubble in the last two decades and will study the first stars of the universe to find signs of life and creating worlds.

It is nearly 15 meters wide and has 40 times the light-gathering power of Hubble thanks to 120 different segments that work in harmony to deliver extremely high-resolution data.

Each individual section is powered by pistons, allowing it to erect itself and at the same time fold as a 25-tonne origami piece.

HabEx will specialize exclusively in the last goal of LUVOIR, exclusively looking for signs of habitable planets. It will begin its journey with an accompanying spaceship designed to block disturbing glare from a nearby star.

With this star shield the size of a soccer field, HabEx can obtain detailed images of exoplanets.

Lynx is designed to succeed Chandra in analyzing X-ray emissions from the entire universe that are scattered through black holes.

By following this path, scientists can compile the mysteries of the formation of galaxies and galaxies.

Origins approaches an approach like none of the other three and is designed to study a specific band of infrared radiation that is produced by cold gases and cooled bags of space dust that eventually come together to form planets and stars.

It will obtain this cold data by being constantly cooled to within four degrees of absolute zero (-273.15 ° C) – the temperature at which all motion stops, even that of atoms.

NASA has produced designs of the four concepts and has said that the winner is likely to be placed on L2 – an astronomical position a million miles beyond the Earth and in the opposite direction from the sun.

WHAT IS A LANGUAGE POINT?

A Lagrange point is a place in space where the combined gravitational forces of two large bodies are equivalent to the centrifugal force of another body.

The way in which the forces act on each other creates a net directional force of zero and allows an object to remain stationary in space.

These points are named after Joseph-Louis Lagrange, an 18th-century mathematician who wrote about it in 1772.

major astronomical bodies have five points – labeled L1, L2, L3, L4 and L5.

L1, L2 and L3 are all unstable because they are completely dependent on a fragile balance.

L4 and L5 are much more stable.

L1 – Between the two objects. This location between the sun and the earth is currently occupied by SOHO – Solar and Heliospheric Observatory and the Deep Space Climate Observatory.

L2 – The second place is a million miles beyond the earth and in the opposite direction from the sun. This is currently occupied by NASA & Wilkinson Microwave Anisotropy Probe (WMAP) and will be the target area for the coming James Web telescope.

L3 – This place is behind the sun and away from the earth. This place is not yet occupied.

L4 and L5 – They lie along the orbit of the earth at 60 degrees before and behind the earth.
