James Webb Telescope Launch Delayed Until 2020

Tue Mar 27, 2018 4:05 pm

According to Space.com, the James Webb telescope launch will be delayed by nearly another year due to the need for more testing.

Congress awarded $8 Billion to the project back in 2001. The telescope is being built by Northrop Grumman and will be launched onboard an Airbus Defence and Space Ariane 5 heavy-lift launch vehicle.

$8 billion spent, and the engineers are still struggling with decidedly low tech systems of cables and pulleys?

Well, it's not great news, but to be honest, this is a very ambitious and very complex mission with no room for error... at all.

I'd rather they delayed it by several years to make extra triple sure that everything is going to work than to end up with a $8bn piece of space junk floating around the Sun.
Not to mention that if it failed, the funds for a replacement mission would probably not be approved in my lifetime.

As francoflier states there is no room for error -at all.And the 'in space 'automatically assembling technology is an accident waiting to happen.
It's such an important project,perhaps (imho) the most important of all it would be terrible if it went wrong.I guess everybody following this project is frustrated.
On a separate thread I pondered whether a deep space man rated product such as Orion or indeed BFR could go out to the 'point' where it is stationary to try and fix it if it did go wrong.The SLS doesn't have many (any?) missions.Perhaps that could be one if necessary.

Whilst it would cost a shed load to build I noted that the BFR cargo vessel can house a 9Mtr satellite.Which could therefore be the size of a mirror.A much safer way to launch such a beast.
Trying to peer back to the earliest 'first light' of the universe is probably going to be key to finding out whether the present Big Bang/Inflation theories are right or wrong.(probably the latter!).

The James Webb telescope is like an intricate piece of origami that needs to be folded correctly while i'ts in space. And the last space vehicle built by Northrop Grumman didn't fare so well, at least that's the rumor. They better get it right.

The antenna on the Galileo mission.

https://en.wikipedia.org/wiki/Galileo_(spacecraft)#Main_antenna_problem

Somebody mentioned it on a.nut, and it shows how difficult it is to design anything space-related. And the circumstances leading to the Galileo antenna problems (decaying lubrication) were entirely unforeseen.

What a dissapointment. I was really looking forward 2018 then 2019 launch, now it has been postponed again! : :indifferent: :mad:
I understand that JWST is a marvel of engineering, and at L2 there is no repair mission possible, still...

If JWST survives launch and deployment, we will see the first stars and galaxies form.

Eagerly waiting the day of launch. :crossfingers:

At least, there are great things going on.

The telescope's predecessor, the Hubble, was originally the poster child for a botched project. It took some Space Shuttle visits to get it working right, and now that Hubble is working, it has proven to be an enormously valuable asset.

Better to get it right and not come out of the gate like another Hubble. And this time around, no one is guaranteeing any maintenance visits either.

And FYI - my computer's desktop background is a Hubble shot. It is amazing what Hubble has achieved in light of its experiences.
