The Webb Telescope will be a powerful sun of a gun, and will operate in the
infra-red band rather than visual, which is good because there is a lot of
dust in the Universe and we want to see what is behind it.

The thing that concerns me is that the Webb Telescope cannot be serviced
after launch. I rate its risk of failure as high, based on experience with
Hubble.


What concerns me is that hubble will be deorbited before webb is operatrional
and webb may finde some areas of interest hubble could of looked at. webb will
lack some hubble abilities too.

In the event of a budget cut or launch failure webb might be delayed or never
occur.

As to service if the new manned launcher really happens we might be able to
service webb. It should be redesigned to permit in orbit repairs.

Wouldnt it be sad to get webb out there, have a part fail that cant be replaced
in orbit because of the design?
