released after repairs
CENTER, Houston (AP) -- After bestowing more than a dozen
gifts on the Hubble Space Telescope, space shuttle Discovery's
astronauts on Saturday accomplished the last big job of their
holiday repair mission: releasing the world's finest observatory
to resume its scientific quest.
Jean-Francois Clervoy used Discovery's robot arm to lift Hubble
from the shuttle cargo bay and, as the spacecraft sped more
than 370 miles above the South Pacific, gently let it go.
The 43-foot telescope gleamed as it slowly drifted away against
the backdrop of a blue, cloud-dotted Earth.

the perfect ending to a NASA-style Christmas, Hubble and Discovery
thrilled their Houston team with a spectacular light show
over NASA's Johnson Space Center. Just two hours after releasing
the telescope, Discovery streaked across the Houston sky with
Hubble following close behind.

Returns Hubble to Duty: Astronomers Ecstatic
By Glen Golightly
Houston Bureau Chief
- The once ailing Hubble Space Telescope soared away from
space shuttle Discovery today - one step closer to being back
in the science business.
370 miles above the Coral Sea, Discovery's crew released the
telescope at 6:03 p.m. EST and began inching their spacecraft
away, careful to avoid damaging or contaminating Hubble with
the shuttle's maneuvering jets.

back into operation.

Eve with the Hubble Family
[One Hubble Girl's Perspective]
by Ann Jenkins
the night before Christmas and here we are in Houston, more
than a thousand miles from our homes and families and anything
resembling a normal Christmas Eve. We're the Hubble team from
NASA's Goddard Space Flight Center in Greenbelt, Md., but
for now, we're living here in Houston, working at Johnson
Space Center, supporting the STS-103 mission. And Christmas
just happens to fall in the middle of this very important
visit to our beloved telescope.
families try to understand why this is so important to us,
why we need to be away during the holidays. We fight to stay
focused and philosophical, but the truth is, as Christmas
looms, we're all feeling the pangs of separation.
thankfully, we're together-our little Hubble family-and most
of us have been for a very long time. Many have worked all
three Hubble servicing missions. Ours is not a 9-to-5 job,
especially in the months leading up to launch. We've been
through a lot together, and we've grown close because of it.
Some of us know each other so well we swear we're becoming
the East Coast, it's already Christmas now. Kevin, who sits
to my left, has three little ones whose pictures he's pasted
all over his console. He talks about them constantly, but
he won't be seeing them on Christmas Day. Maureen, Colleen
and Mindy are apart from their children, too. Come to think
of it, many teammates have kids back home. But these parents
truly believe that this mission will benefit not only their
children and grandchildren, but also generations beyond. This
is their Christmas gift to humanity.
look around the room and search for words to describe this
group. Dedicated.passionate.brilliant.creative.yes, that's
all true-but also so much more. We are a family.
after NASA declared mission success and guided Santa into
Houston, we shared Christmas dinner together here in Mission
Control. Though I can't be with my own family tonight, I feel
very privileged to break bread with this group-a close-knit,
loyal clan bound not by blood but by vision.

NASA's Santa Control has confirmed the jolly old elf

has delivered his presents and then took off again on
a trajectory over the Gulf of Mexico, presumably to
a visit at Cape Canaveral. Of course, your home may
for 7:30 p.m. EST
Discovery is in daylight now, flying over Australia with its
tail first, nearly at the end of orbit number 75.
The spacewalk is expected to last another two hours or so.
The next task is to install the new insulation.
Mission commentator Kyle Herring just plugged the fact that
Houston is about to have an opportunity to see Discovery and
Hubble fly overhead within the hour.
Herring said that NASA's Web site for information about the
possibility of seeing the shuttle in your area is located
for 7 p.m. EST
The new recorder is being checked by flight controllers on
the ground and the door to the area is being closed and latched
with six bolts.
Next up is to install some new insulation on the outer skin
of Hubble, replacing some insulation that has torn and peeled
through the nine-and-a-half years that the observatory has
been in orbit.
If it could all get done, the astronauts would like to cover
six bays with the new insulation. They will do the first two
and then Mission Control will decide what to do next based
on how long they take to do the first pair.
The spacewalk can only last about seven hours and they need
about one hour to do the final clean up in the cargo bay since
the bay must be configured for landing.
for 6:30 p.m. EST
Grunsfeld has the new recorder in place and has bolted it
into place. A few feet lower on the telescope, Smith is installing
devices that will allow the two spacewalkers to install new
insulation on the outer skin of Hubble later tonight.
They have just passed into night again and there are no reports
yet of spotting Santa Claus from space, although Santa was
seen earlier today on NASA TV in Mission Control in Houston.
for 6:20 p.m. EST
Grunsfeld is still in the foot restraint on the end of the
robot arm and has just handed off the old data recorder to
Smith. The new recorder is in Grunsfeld's hands and he is
being moved back up to the telescope to install the new device.
The spacewalk has just passed the four-hour mark.
for 6 p.m. EST
The spacewalking astronauts have finished installing a new
radio transmitter and have moved on to the process of installing
a new solid-state data recorder for the telescope. The 25-pound
device replaces an old-fashioned reel-to-reel tape recorder.
for 4:30 p.m. EST
John Grunsfeld is working diligently to remove a series of
connectors on a failed radio transmitter. The coaxial cables
are a little thinner than the ones you might connect to the
back of your TV or VCR but they have the same kind of end.
Anyone who has had difficulty connecting these cables to your
home electronics might only begin to imagine what it would
be like to try to connect these same type of connectors to
a device in the weightless space environment, while wearing
Grunsfeld does have some tools to help him, and it sounds
like it's going very well, but the fact is that this is one
of the few devices on Hubble that was not designed from the
beginning to be serviced by spacewalking astronauts.
Smith continues to free float, assisting Grunsfeld as needed
and also making inspections of Hubble.
This work should continue for about an hour.
Our next report will come about 5:45 p.m. EST if all goes
well. If any serious problems arise we will update the site
for 4:05 p.m. EST
Mission Control reports that with the successful test of the
OCE package the crew of mission STS-103 has now effectively
completed all of the major goals for this mission from the
viewpoint of the Hubble Space Telescope community. The mission
itself won't be a success, of course, until Discovery's crew
is safely back on Earth next Monday.
for 4 p.m. EST
Mission Control reports that the first repair task today was
successful after the new Optical Control Electronics package
passed its alivness test.
Grunsfeld is still on the robot arm and Smith is free floating.
They have moved to a position more on the front of the telescope
as seen from the flight deck windows, where they are about
to replace a radio transmitter that failed in 1998.
As usual the work involves opening a door, removing electrical
and mechanical attachments for the old unit, installing the
new, taking some pictures of their work and then closing the
doors again. This task should take about an hour-and-a-half.
There was some discussion about taking a few minutes to install
some hand rail protective covers on the telescope but Mission
Control asked the crew to press on with the planned tasks
for 3:30 p.m. EST
Smith and Grunsfeld are mating the electrical connectors to
the new Optical Control Electronics package that is part of
the system Hubble needs to accurately point while stargazing.
The effort is going very well and you can tell that this is
the second spacewalk of the mission for both men as they are
more talkative, in good humor and clearly enjoying their time
out in the cargo bay.
At this point we will begin updating this Web site about every
half-hour, with a longer break at 5 p.m. while I attend my
children's Christmas program at church. FLORIDA TODAY's senior
aerospace writer Robyn Suriano will be monitoring the spacewalk
and we'll update the site immediately if anything seriously
for 3:20 p.m. EST
Mission Control has given the astronauts a go for the first
task today, which is to install some new electronics into
the telescope that will help the Fine Guidance Sensor.
The work area is fairly high up on the telescope. Smith is
free floating and climbed up the telescope himself, with Mike
Foale from the inside of Discovery reminding him to stay tethered
to Hubble at all times.
Grunsfeld, on the other hand, had to request a ride on the
end of the arm, asking Jean-Francois Clervoy to "beam me up!"
you up," Clervoy replied.
This work area is more "behind" the telescope than the other
areas and very near the solar arrays. The spacewalkers outside
and Mike Foale directing things from the inside are constantly
reminding each other not to lean back.
At 3:17 p.m. the spacewalkers had the door to the Bay C area
open and were about to tether the door open and begin removing
electrical connectors on the old piece of equipment.
for 3 p.m. EST
Daily set up was officially complete at 2:58 p.m. EST.
Grunsfeld is in the foot restraint at the end of the robot
arm on the foot restraint. Since he is wearing Mike Foale's
top half of the spacesuit parts of his upper suit has a broken
red stripe on it.
Meanwhile, Mission Control reports that the portable foot
restraint that kept flopping around yesterday because of a
stuck foot switch will not be used today. A second device
will be used instead.
At the end of the spacewalk the balky platform will be attached
and secured in the cargo bay as planned for the landing.
Also, just a minute ago a robot arm TV camera pointed down
on Florida. We waved out the window and captured the image,
which we'll post online in a few minutes. Consider it a Christmas
wave from Space Online via NASA TV.
for 2:45 p.m. EST
Both men can now be seen on NASA TV outside in the cargo bay.
Steve Smith has worked his way down to the area where Hubble
is attached to the cargo bay. John Grunsfeld is still working
at the airlock in and around the robot arm.
Once again, Smith's suit has a solid red stripe, while Grunsfeld's
suit has no markings.
For the record - I think I finally have it straight - the
idea of marking the spacesuits to tell the difference between
astronauts was to begin with the Apollo 13 mission with red
markings on Jim Lovell's suit. But we never saw those pictures
on the moon following the mission's abort.
During the July 1969 Apollo 11 mission you couldn't tell the
difference between Neil Armstrong and Buzz Aldrin. By the
time the idea was presented to mark the suits it was too late
for Apollo 12's mission in November 1969 with Pete Conrad
and Alan Bean. (Not that it really mattered because of the
lack of TV coverage of the moonwalk after the failure of the
Apollo 14's Alan Shepard was the first to be seen on the Moon
wearing a suit marked in red.
for 2:35 p.m. EST
Routine set up chores are in work right now, including retriving
tools from the airlock to attach to the mini work station
on the shuttle's robot arm and installing what is essentially
another leg for the ring platform holding Hubble in the cargo
The first major task will be to install some new electronics
that will help the Fine Guidance Sensors do a better job in
helping point Hubble while it makes its science observations.
for 2:30 p.m. EST
Steve Smith is now outside the shuttle's airlock, floating
in the cargo bay. He left just about three minutes ago.

open the thermal cover to the outside hatch. "Oh look at that

power and 99 percent oxygen. Suit had 18.1 volts DC and 3.4
I did not copy Grunsfeld's report.
for 2:17 p.m. EST
With no radio traffic or mission control commentary describing
the airlock depressurization, Mike Foale performed a radio
check and then the next thing you know Smith and Grunsfeld
were on their batteries, officially beginning this third spacewalk
at 2:17 p.m EST, according to my clock.
The airlock is depressurized, the hatch is open and the two
spacewalkers are just about ready to float outside.
for 2:10 p.m. EST
The lead Orbit 1 flight control team have taken charge in
the Mission Control Center. That means that Linda Hamm is
the flight director, astronaut Steve Robinson is the CAPCOM
and mission commentator is Kyle Herring.
Among the goals for today's spacewalk: replace a recorder,
install some new electronics and add some new layers of insulation
to the outer skin of Hubble.
for 2 p.m. EST
Steve Smith and John Grunsfeld are inside Discovery's airlock
pre-breathing pure oxygen to rid their bloodstreams of any
nitrogen, to avoid getting the bends when they expose their
bodies to the lower air pressure inside their spacesuits.
for 1 p.m. EST
Mission Control reports that Steve Smith and John Grunsfeld
are right on the timeline preparing for today's spacewalk
and will likely begin their adventure at 2:20 p.m. EST. The
spacewalk is expected to last about seven-and-a-half hours.
There are no problems reported with the new suit that John
Grunsfeld will wear today. The one he wore during Wednesday's
spacewalk would not power up properly today, so he is going
to wear the spacesuit that Mike Foale wore yesterday.
Once the two men are outside we will provide updates to this
page every 30 minutes.
for 12:30 p.m. EST
Preparations today for the third spacewalk ran into a minor
hitch this morning in that one of the spacesuits power system
wouldn't properly work, forcing a last-minute change to use
a back up spacesuit instead.
The Extravehicular Mobility Units - spacesuits - come in two
major pieces, the top and the bottom. Both the tops and the
bottoms come in standard sizes, which can be somewhat adjusted
for a particular astronaut. Long gone are the days when an
astronauts spacesuit was sized just for him.
Haven't heard an exact time yet when the crew thinks they
can begin the spacewalk today. We'll pass that along as soon
as we hear.

Mike Foale could be seen on NASA TV entering the airlock at
10:03 p.m EST and shutting the thermal cover for the outer
airlock hatch behind him.
The hatch was closed by Foale at 10:07 p.m. EST.
Nicollier and Foale went off suit battery power (unofficially
based on my clock) at 10:11 p.m. making this spacewalk eight
hours and five minutes long, the third-longest spacewalk in
U.S. space history.
The second longest was completed yesterday at eight hours
and 15 minutes, while the longest was in May 1992 aboard shuttle
Endeavour at eight hours and 29 minutes.

The two spacewalkers are stuffing the airlock with some of
their tools, as well as the balky portable foot restraint.
Nicollier entered the airlock at 9:54 p.m. EST and it appears
he's inside to stay.
Foale is still outside, but right at the airlock's entrance
stowing his tethers.
for 9:45 p.m. EST
At 9:37 p.m. Mike Foale's spacesuit sent him an alarm saying
his suit is running low on battery power. The spacewalk was
seven hours and 31 minutes long at that point.
Anticipating the suit warning, CAPCOM Steve Robinson radioed
to Foale a moment earlier that when Foale heard the alarm
he could ignore it because at that point Foale still had another
90 minutes of power. At the beginning of the spacewalk, when
Foale read aloud his suit status, he said he was good for
seven hours and 59 minutes.
Mission Control says the pair of spacewalkers should be inside
and off the suit power in about 20 minutes, making their spacewalk
duration about eight hours. Both men are now in the vicinity
of the airlock.
for 9:30 p.m. EST
During the clean up operation Foale attached the portable
foot restraint to its storage place and then discovered a
Although the pin holding the device to the shuttle was secure,
the platform itself would not stop from flopping around -
apparently a problem with a switch that allows the astronauts
to move the platform back and forth in a pitching motion while
their feet are locked in place.
Mission Control has decided the crew should bring the platform
inside, despite its relative bulkiness, and let them troubleshoot
the problem overnight.
The platform will have to come back out tomorrow, possibly
to be used, although there is a second portable foot restraint
device on board.
The safety concern is that mission managers do not want the
device flopping around during the landing, so they are going
to figure out the best way to tether it in place in the cargo
bay if the switch cannot be fixed.
for 9:15 p.m. EST
Clean up work continues in the cargo bay.
Nicollier is still on the foot restraint at the end of the
robot arm, suspended in the middle of the cargo bay and working
on his mini-work station.
Foale is behind him, next to the equipment storage boxes near
the base of the telescope.
Note: Earlier I wrote that Nicollier had been present for
the five Hubble spacewalks in 1997. I actually wrote 1993,
which is correct, but a solar flare must have bit-flipped
the number to 1997 when I uploaded. I've corrected the earlier
entry and thanks for the e-mail from several European friends.

The old Fine Guidance Sensor has been placed in its hold in
the cargo bay, strapped into place and the door to the box
shut according to what we can see on NASA TV at this time.
for 8:50 p.m. EST
The thinking is that with the clean up work still to do and
the remaining suit time available to the two crewmen it wasn't
a good idea to try anything else tonight.
Now six hours and 44 minutes into the spacewalk.
for 8:45 p.m. EST
Shuttle Discovery's crew has politely asked to do some more
work outside today, but Mission Control politely said no thanks.
As a result the spacewalkers will be cleaning up and moving
inside within the hour.
for 8:30 p.m. EST
The doors to the Fine Guidance Sensor are closed and Nicollier
is driving the three bolts to latch the doors shut.
Meanwhile, Hubble flight controllers report the new Fine Guidance
Sensor has passed its initial aliveness test, meaning they
are able to see electrical power and data commands go through
The view from NASA TV right now shows the shuttle approaching
sunrise, with a bright blue horizon in the background as the
crew works in the dark. Truly incredible.
for 8:15 p.m. EST
The newly installed Fine Guidance Sensor is ready for its
aliveness test after all eight connections were mated by the
two spacewalkers and the work to load the new unit into place
was declared done.
After the initial trouble sliding the nearly 500-pound box
into place, CAPCOM Steve Robinson from Mission Control congratulated
the crew saying: "Great work, persistence pays."
The two spacewalkers are now taking detailed pictures of their
work with the new sensor unit. Next step will be to close
the doors to the work area.

in Space: How to Be a Hubble Spacewalker
By Andrew Chaikin
floating in the cargo bay of the Space Shuttle Discovery,
365 miles above the Earth. Before you, anchored in a special
mounting, is the Hubble Space Telescope. Your mission, simply
stated, is to fix it. In other words, you have been assigned
one of the most demanding jobs ever given to an astronaut.
you're working on a satellite designed to be serviced in space
by astronauts. Hubble is outfitted with handholds for the
spacewalkers to grab onto. And its components are relatively
accessible, by opening special access doors. But that doesn't
mean your orbital repair job is easy. First off, you're working
in a pressurized space suit. And if you want to know what
that's like, just ask Story Musgrave, one of the four spacewalkers
on the first Hubble repair mission in 1993.
Woes of Working in a Space Suit
are hard," Musgrave says. "They're just miserable. Because
they're so stiff." Shuttle space suits are filled with oxygen
at a pressure of 4.3 pounds per square inch. That gives the
spacewalker enough oxygen to breathe -- but it also makes
the suit about as flexible as a balloon in a Thanksgiving-day
that reason, Musgrave was fussier than the finest tailor about
the fit of his space suit. To bend at the waist, for example,
he would need as much leverage as possible. To achieve this,
Musgrave knew, his feet and shoulders would have to make firm
contact with the suit itself. He also knew that during a six-hour
spacewalk, being inside a tight-fitting suit would compress
his spine -- which meant the suit had to be even tighter at
the start of the day. "I wear a very, very, very tight suit,"
Musgrave wriggles into his spacesuit
paid special attention to the fit of his gloves. Before the
flight, he says, "I spent two hours 'tuning' my gloves. I
tune every finger." That meant having more pressure on his
fingertips and less at the places between the fingers. It
meant precisely adjusting the length of each finger of each
glove, so that the glove's joints would coincide with those
of his fingers.
"You learn a new body."
after you have your space suit perfectly adjusted, Musgrave
says, don't expect it to feel like a second skin. "You learn
a new body. You acquire a new arm. It's not your arm. It's
not the suit arm. It's the combination of your arm and the
suit arm. The suit does not have the same joints you have,
and so you have to learn appropriately."
says a prospective spacewalker has to relearn even simple
motions -- for example, grabbing a floating tool. "If you
think you're going to get into a suit and reach out for something,
you're going to miss it," he says, unless you practice it
just what Musgrave did -- hour upon hour of practice, using
a number of methods. First, he did "walk-throughs", wearing
normal clothes, with engineers who helped design the Hubble
instruments right there, to answer any questions.
also practiced on something called the air-bearing table:
picture him perched a special platform that rides across an
ultra-smooth surface, cushioned by a thin film of pressurized
air. Working in weightlessness is like being on a three-dimensional
ice-skating rink, and the air-bearing table is designed to
show an astronaut how tricky that can be. However, it only
allows freedom of motion in two dimensions at once.
there was the "Neutral Buoyancy Laboratory", actually the
world's largest swimming pool, containing mockups of the shuttle
cargo bay and Hubble telescope. Underwater, wearing a pressurized
space suit, an astronaut can practice working in three-dimensions.
But there are drawbacks. Unlike the vacuum of space, water
creates resistance whenever you try to move through it. And
of course, a space-suited astronaut in the "water tank" doesn't
enjoy the weightless conditions of a real space walk. Being
upside down, for example, feels more like standing on your
head -- and you're likely to feel your shoulders digging into
the metal bearings inside your space suit. "The water ?is
no darn good," Musgrave says. "Even NASA doesn't really know
about all the weaknesses [of practicing] in the water."
never used a checklist. Because ... a ballerina doesn't
have a checklist and neither does an opera singer ...
We learned it by visualization."
Story Musgrave - Former Hubble Repairman
Musgrave had spent countless hours rehearsing for the Hubble
repairs by the time he and his crewmates left Earth. And most
of all, Musgrave had spent a lot of time thinking about everything
he would do during the Hubble repair. In fact, he'd been thinking
about how to repair a space telescope for about 20 years --
most of his astronaut career.
how did he feel, as he awoke on launch morning, with one of
NASA's most important missions ahead of him?
just like going to the Olympics. You are totally trained.
You are honed to the edge.. You've done what you can do. That's
it." Even so, Musgrave says, he could never be sure of success.
"You don't know whether you're going to win the Olympics.
How could you know?" In the end, he says, he looked at the
challenge the way a high-jumper does: "It's you and the bar."
When Musgrave finally emerged from the Space Shuttle's cabin
into the vacuum of space, there was a sense of familiarity
about it all. Not just because he'd trained so hard, but because
he'd walked in space before: Musgrave had made the first walk
of the shuttle program, in 1982. And months of practicing
for the repair had given him an extraordinary familiarity
with the Hubble's components.
example, if Musgrave's job was to install a new high-resolution
camera, he made sure he could visualize exactly what was going
on inside the instrument with every turn of every screw. If
that sounds like the ultimate nuts-and-bolts experience, then
Musgrave has a surprising description of the repair:
was a ballet."
ballet? Two figures in bulky space suits and massive backpacks
aren't exactly the picture of grace. And yet, Musgrave strove
for dancer's grace in his movements. "You have to worry about
every finger and toe. If you've got a hand out of place in
the ballet . you're going to lose style."
training, he says, "I would go through ballet books page after
page," studying the dancer's version of perfection, and translating
it in his mind to perfect space-walking technique.
does that perfect technique look like?
a Hubble repair, it often means working in confined areas,
like the access doorway leading to a delicate scientific instrument,
without moving your body. In such situations, Musgrave says,
"The ideal form for a space walker is to see a lot of motion
at the wrist level, less at the elbow and almost none at the
another aspect of a dancer's method that the astronauts used:
Visualization. "We never used a checklist. Because, you know,
a ballerina doesn't have a checklist and neither does an opera
singer... We learned it by visualization." The same technique
let Musgrave keep track of some three hundred separate tools.
He and his fellow spacewalkers had tools to handle every possible
contingency. And yet, even in weightlessness, in the shuttle's
cavernous cargo bay, Musgrave says he never lost track of
them. "You could ask me halfway into [any spacewalk] where
all three hundred tools were, and I could rattle them off."
keeping track of the tools sounds tough, try using them. The
hardest part of any spacewalk, Musgrave says, is working with
your hands in pressurized gloves. If you want to understand
why, try squeezing a tennis ball, repeatedly, for hours on
end. Opening and closing your hand inside a space-suit glove
is just as tiring. For that reason, Musgrave says he tried
to avoid clutching objects. "Any time I see myself grabbing
I say, 'Is there another way to do it?' I don't grab things.
I push and I touch." To use a power tool, for example, he
cradled it between his two gloves, without actually holding
Musgrave during his first Hubble spacewalk
some jobs required an almost impossible level of dexterity.
Musgrave remembers that in order to install one component,
he had to undo ten sets of connectors, which were secured
by tiny screws -- and he had to do it while his feet were
anchored on the shuttle's sixty-foot robotic arm.
were little connections in the back of this box, the size
of what's in the back of your PC. And they had little screws
that are only about three millimeters long. I had a wrench
that was about three feet long, and I was on the end of a
sixty foot arm, and I had to drive these little screws three-and-a-half
was hard enough with space suit gloves. But keeping the screws
from floating away -- possibly inside the telescope's delicate
mechanisms -- made it even tougher.
was the most demanding job I had ever done," Musgrave says.
"I was on the edge of my ability."
Glow of Success? Not Really
made three of the mission's five spacewalks. When it was all
over, Musgrave knew he had done his job well. But he didn't
share his crewmates' jubliation at a successful mission. "I
put on a smile for people," he remembers. "I felt humble and
quiet." The reason, Musgrave says, is that he couldn't be
sure, even then, that the telescope was fixed. He didn't know
that until the repaired Hubble sent back its first new images.
that time, Musgrave was back home, in Houston. He remembers
the thrill of seeing Hubble's magnificent face-on image of
the spiral galaxy called M-100. Even then, Musgrave says,
he didn't think about what he and his crewmates -- along with
dozens of flight controllers, mission planners, and engineers
-- had helped to accomplish.

lazer aimed at the telescope, the distance between Discovery
and Hubble agrees with the shuttle's radar.
The shuttle's radar
uses the same Ku-band antenna dish that live TV is transmitted
to Earth on. The Ku-band antenna can be used for communication
or navigation, but not both, which is why there is no pictures
from space yet on NASA TV.
Earlier, mission commentator
Kyle Herring said there is a chance that once the shuttle
gets close enough to Hubble and can't use its radar anymore,
that the switch to TV might be possible and some pictures
could be beamed back.
If not, the crew is
recording this rendezvous on tape and is scheduled to play
it back later this evening.
Discovery now approaching
the "R-bar," which is an imaginary line drawn from Hubble
down to the center of the Earth. Once the shuttle hits the
R-bar it will stop and move up the line to complete the rendezvous.
Update for 6:52
A fourth burn has
taken place and Discovery is now 1,780 feet away from Hubble,
closing at a rate of 2.2 feet per second.
Curt Brown, floating in the rear of the flight deck, will
now take over the final manual approach to the telescope.
Update for 6:35
A third midcourse
correction burn following the TI burn has taken place and
Discovery is now about one mile away from Hubble.
The astronauts report
they can see the observatory through the optics of one of
their navigation devices.
Discovery is moving
about 6 feet per second toward Hubble, which is reported ready
for Discovery's arrival.
Update for 6:10
Discovery is now about
four miles from Hubble.
Mission Control has
reported that a communications link between the ground and
Hubble through Discovery has been established.
Update for 5:30
Terminal Initiation burn using Discovery's reaction control
system jets has taken place without incident. The shuttle
is now on a course that will have Discovery and the Hubble
Space Telescope coming within 30 feet of each other in about
The two are separated
now by under 10 miles.
Update for 5:12
have been given a "go" for the TI burn. This small firing
of the shuttle's steering jets will send the shuttle on an
intercept course to Hubble.
The scheduled time
of the grapple is 7:41 p.m. but the exact time will depend
on the precise orientation of Hubble once Discovery arrives.
Hubble is in safe mode right now following the failure of
a gyroscope several weeks ago, so its exact orientation in
space relative to the shuttle and Earth is not known.
Curt Brown will have to look over the situation and manually
fly Discovery into the proper position next to Hubble so the
robot arm can be used to grab the telescope. This might require
the exact grapple time be adjusted.
Update for 4:45
All still proceeding
smoothly for the rendezvous with Hubble.
Update for 2:45
Discovery is slowly
approaching the Hubble Space Telescope and is now about 47
miles away from the observatory.
Curt Brown and pilot Scott Kelly have made a series of course
corrections today to close the gap between the shuttle and
the telescope. The final approach to Hubble is expected to
begin at 5:28 p.m. with the so-called Terminal Initiation,
or TI, burn.
Less than two hours
later Discovery will be within 30 feet of Hubble, and then
Jean-Francois Clervoy will operate the shuttle's 50-foot-long
robot arm to grab the telescope at 7:41 p.m. EST and move
it into position in the cargo bay and set it down in a cradle
at 8:01 p.m. EST.
Abour 39 minutes later
cameras on the robot arm will be aimed at the telescope and
the astronauts and Mission Control will inspect the exterior
of the observatory.

"Over the last 10 years, we've taken great leaps in answering
basic questions about the universe, and more importantly,
in (finding out) the things we don't know. "I think Hubble
has done a real good job putting us in our place."
The orbiting telescope was designed to be worked on by spacewalking
astronauts, and a good thing, too. Unbeknownst to NASA, the
$3-billion observatory was launched in 1990 with a faulty
mirror that kept it from seeing clearly.

astronauts made repairs in 1993. Another group returned to
the telescope in 1997 to give Hubble a tune-up.

objects one billion years after the Big Bang, perhaps as little
as 800 million years after the Big Bang, which means the epic
of galaxy formation occurred much earlier than most models
predicted," Weiler said.
Scientists always believed black holes existed, but had no
proof. Hubble changed that in 1994, when it first took images
of matter swirling around the gaping center of a black hole.
