this
is the hubble space telescope the hubble
space telescope
hubble space telescope hubble space
telescope a window on the universe
it is a piece of engineering and
astronomical majesty that is captured to
the most astounding images
of the cosmos i could only say there was
one word to describe these images and
that's just absolutely incredible
but hubble's journey didn't start out
that way specialist kathy thornton
they're making their way down
and we have a debra houston for dolph
getting us a leg up on the solar rate
changeover the next day i'm just
[Music]
as hubble was being planned and built
engineers designed the telescope to be
worked on by astronauts in space
it was equipped with handrails and its
instruments were made to be easily
removed and replaced
nasa and astronomers wanted to upgrade
hubble throughout its life
they could install latest technologies
and repair parts that broke or became
damaged while in space
liftoff of the space shuttle discovery
with the hubble space telescope
soon after hubble's launch and
deployment in 1990
that ability to fix hubble became more
critical than
anyone had ever imagined
when hubble's first images reached earth
something seemed to not look
quite right literally conclusion we've
come to from that
is that there's a significant spherical
aberration appears to be present in the
optics
it was soon discovered that hubble's
primary mirror was ground too flat
and it caused the images to be out of
focus
public apprehension soon began to rise
and nasa's competency began to be called
into question
okay the bottom line is do we have a fix
for this as i said the biggest impact
right now is the loss of spatial
resolution the wide field camera
with the focusing issues of the primary
mirror and two of hubble's gyroscopes
failing the
need for this servicing mission was
urgent
i know we're going to succeed at this
and we're going to turn the hubble space
telescope
in all regards into the exciting
scientific instrument that we expect
it to be seven astronauts who began
training for this all-important first
servicing mission were more than
prepared to repair
hubble
when december 2nd 1993 finally came nasa
was ready
and we have liftoff lift off of the
space shuttle endeavour
on an ambitious mission to service the
hubble space telescope
successfully they navigated installing
new solar rays that would not expand and
contract when they went in and out of
sunlight
allowing hubble to remain steady when
taking photos
they replaced failing gyroscopes and
magnetometers enabling for more accurate
manipulation of the telescope's
orientation
[Music]
installed a wide field planetary camera
2 which had 48 color filters covering a
spectral range from ultraviolet
to visible wavelengths and housed extra
mirrors to correct for the flaw in
hubble's main mirror
and of course they adjusted the hubble
space telescope's vision with a
corrective optics space telescope axial
replacement
or costar that acted almost like a pair
of glasses for the primary mirror
fixing the spherical apparition for the
rest of hubble's instruments
after five days of intense repairs and
maintenance
the hubble space telescope was back up
and running
pictures are remarkable the science that
will come from the pictures
are of historical significance
and now we are able to clearly see
[Music]
this
[Music]
the first servicing mission to hubble
restored the telescope's original
expectations and then so much more
without it the hubble space telescope in
nasa for that reason might not be where
it is today
over 30 years later
[Music]
thanks to the hubble space telescope and
the team behind servicing mission one
we can now behold these amazing
astronomical
[Music]
encounters
