World’s most advanced space telescope set to launch on Christmas Eve

After 20 years in the making, the James Webb Space Telescope is finally set for launch.

On Christmas Eve, the $10 billion space observatory will lift-off on a European Ariane 5 rocket from a spaceport near Kourou in French Guiana, South America.

The telescope will be capable of looking back 13.5 billion years to see the first stars and galaxies of the universe and search for signs of life.

It has been in development by US and European space agencies for two decades and faced several delays.

After several launch delays this year alone, a date of December 22 was set, but technical issues pushed it to December 24 at 4.20pm Gulf Standard Time.

The team discovered a faulty data cable between the telescope and launch pad equipment at the spaceport, which was causing communication issues between the two.

The problem was resolved and the launch was back on. Dozens of engineers and scientists will be working through the holidays to make the launch a success.

“For us this is a historic moment that took 20 years to come. What we have not understood is what happened about 13.5 billion years ago, when a universe that was largely made out of protons and helium turned into something that made galaxies for the first time,” Thomas Zurbuchen, science mission directorate associate administrator for Nasa, said at a space conference held in Dubai earlier this year.

“That’s what we’re going to observe. It’ll be like looking at baby pictures of that universe.”

What’s special about this telescope?

Once operational, the James Webb Space Telescope would be 100 times more powerful than the Hubble Space Telescope, which for 31 years has made countless discoveries and provided millions of images of planets, galaxies, nebulas and stars.

It would be placed in a different orbit than the Hubble and much further out in space, allowing it to see greater distances.

That position in space is known as a Lagrange point, meaning it will follow Earth around the Sun

This strategic location would enable it to see further in space than any other telescope. It would detect some of the first galaxies, study the atmospheres of exoplanets, or planets outside of the Solar System, and search for any oxygen present.

How will it see back in time?

To study the early universe, the telescope will be able to see 13.5 billion light years away, meaning it will see 13.5 billion years back in time.

Telescopes are described as ‘time-travel machines’ because they observe distant objects. The light from these objects take years to travel to Earth, so the telescope sees the object at the moment it released the light.

Mirrors are an important component. On the James Webb Space Telescope, 18 primary mirrors are built together in the shape of a honeycomb that measures 6.5 metres in diameter – six times bigger in area than Hubble’s.

To help reflect infrared light more efficiently, the mirror is covered with a thin coating of gold.

The mirror will be kept at a temperature of minus 233°C to shield it from the Sun. It has a five-layer sunshield that is the size of a tennis court, which makes the heat from the Sun more than a million times weaker.

Terror attacks in Paris, November 13, 2015

- At 9.16pm, three suicide attackers killed one person outside the Atade de France during a foootball match between France and Germany- At 9.25pm, three attackers opened fire on restaurants and cafes over 20 minutes, killing 39 people- Shortly after 9.40pm, three other attackers launched a three-hour raid on the Bataclan, in which 1,500 people had gathered to watch a rock concert. In total, 90 people were killed- Salah Abdeslam, the only survivor of the terrorists, did not directly participate in the attacks, thought to be due to a technical glitch in his suicide vest- He fled to Belgium and was involved in attacks on Brussels in March 2016. He is serving a life sentence in France

TERMINAL HIGH ALTITUDE AREA DEFENCE (THAAD)

What is THAAD?

It is considered to be the US's most superior missile defence system.

Production:

It was created in 2008.

Speed:

THAAD missiles can travel at over Mach 8, so fast that it is hypersonic.

Abilities:

THAAD is designed to take out  ballistic missiles as they are on their downward trajectory towards their target, otherwise known as the "terminal phase".

Purpose:

To protect high-value strategic sites, such as airfields or population centres.

Range:

THAAD can target projectiles inside and outside the Earth's atmosphere, at an altitude of 150 kilometres above the Earth's surface.

Creators:

Lockheed Martin was originally granted the contract to develop the system in 1992. Defence company Raytheon sub-contracts to develop other major parts of the system, such as ground-based radar.

UAE and THAAD:

In 2011, the UAE became the first country outside of the US to buy two THAAD missile defence systems. It then stationed them in 2016, becoming the first Gulf country to do so.
