Humans are developing at a very fast pace and are achieving a
lot of things very quickly. Our curiosity to do everything has forced us to do
the most challenging things and perform things that are not very easy.
Development related to space is at its peak and there are many agencies working
right now. We have achieved a lot up till now but that’s just the beginning. In
the upcoming centuries, we will probably become an intergalactic civilization,
which will conquer space unless somehow, another extraterrestrial life invades
us. So, let’s start already. In 2021, NASA will launch the James Webb
Telescope.

The making of this telescope is the largest, most expensive
and the most challenging space-engineering project the humans have ever attempted.
NASA has been working on this project for 30 years. This telescope is not the
only of its kind, but humans also launched another telescope named as Hubble in
1990. Hubble telescope experienced some technical problems but, after it was
fixed, it worked just fine and it literally rewrote our perception of the
universe. Though Hubble can see objects that are very distant, it cannot see
things farther than a specific limit. This is where the James Webb telescope
kicks in which can take images in more detail and higher distance than the
Hubble telescope and can see objects that have details about the origin of the
universe. This telescope will help us understand how the universe started and
how it formed. It would uncover the forces of the universe and the evolution
of how many objects formed in the universe. Not only will this telescope help
us see the past of this universe, but it will also help us predict the fate of many
of the galaxies, stars, etc. This telescope has the ability to capture infra-red the light that ultimately helps it significantly in finding objects much farther
than the Hubble could see. The main problem though is that the Sun also emits
infra-red light so, how do we keep the infra-red light from the Sun away? Well,
this telescope has a sun shield that literally blocks all the light from the Sun
from reaching the telescope’s camera. We still have a lot of problems to tackle
before we launch this but, one problem is what we all have to pray to end
well. That problem is the launch. Now, we know that rocket launches are
extremely hard and have a high chance of failure. Therefore, we have to launch
this telescope perfectly into space or else, a lot of money, effort and time
will be wasted. This telescope will be launched into orbit at a very far distance,
at a point called the Second Lagrange point. This point in orbit is 1.5 million
km away from the Earth though it is still in the zone of orbiting the Earth.
The advantage of this orbit is that it would clear out a huge space for the
telescope to see.
This blog was the first of this series and I will write more
blogs on the topic as we still have another 79 years to cover.
