three minus 15 seconds and counting
also there's go 10987 we have a go for
engine start three two one ignition and
liftoff discovery now on its way to
service NASA's Hubble Space Telescope
Houston now controlling
roll maneuver is complete aboard
discovery the vehicles now in a
heads-down position on course for a
twenty eight and a half degree 309
nautical mile orbit discovery already
one and one and a half miles in altitude
and downrange from the launch site one
and a half miles as well three main
engines beginning to throttle down now
as the orbiter prepares to pass through
the area of maximum dynamic pressure on
the vehicle in the lower atmosphere the
three engines now at 67% of rated thrust
the engines now beginning to throttle
back up
his discovery we have Italian happy doc
it must be a beautiful sight yeah big a
price that is to learn free drift and
dr. Steve he's going to get self cope
and we see that dark
Kelly joined discovery see I wish you
could see the expression on dr. Stevie's
face looks like he just shook hands with
an old friend
dot mark they should coming up seven and
a half two nothing turns and of course
you watch for the washer
and as we can see mark Lee now using the
power ratchet tool to remove the six
captive washers bolts and washers there
are three on either side of this data
interface unit all of the 18 cables now
have been removed from the side of the
box
since these are not captive bolts and
washers the crew has to be very careful
when they are removed and you could see
mark Li after removing that first bolt
putting it in a temporary stowage
position on the temporary handhold that
he's installed on the DI you
and as can be seen from this picture
discovery is approaching an orbital
sunrise as it heads across the upper
northwest portion of Africa reaching the
midpoint of the 73rd orbit of
Discovery's mission this view from the
elbow camera on the shuttles robot arm
Steve Smith on the right the
free-floating astronaut with while Mark
Lee with the red stripes on the legs of
his suit mounted in the shuttles
manipulator foot restraint on the
shuttles robot arm
slightly left jump slightly left a
little bit more
we're looking at it and it's a great
view
this view over the left shoulder of
Gregg Harbaugh the eight connectors on
the solar array drive electronics box
are very similar to the connectors on
the back of a processing unit on the
back of a home computer the two tiny
screws he just D mated from the first
connector he's now set to D mate one
connector and connected to the new unit
and this discovery for Greg and Joe
stories got a big smile on his face and
he's given you a big thumb thumbs up
we're both envious and I'm sure that you
you join us and wanted to congratulate
the designers up at Goddard who came up
with this really elegant solution to the
problem that conversation between Jeff
Hoffman here in Mission Control
referencing this same task that they
performed three years ago on the top or
in the number one solar array drive
electronics box the newly designed
connectors much more evie a friendly the
old design had the crew members changing
those out directly against the box
itself
again the plan is for Greg Harbaugh to
disconnect each one of these connectors
one at a time and then connect it to its
new location on the refurbished SolarAid
drive electronics box
say things all in good shape on this
connector unlatched
and Greg Harbaugh will place this pistol
grip tool directly on the tiny screws on
either side of each
that one is free
this moratoria fallenness so change one
of the city
alright I just flipped it slightly out
on the setting and if man was a call
earlier that's happened actually to both
mark and I a couple times
Gregg Harbaugh and Joe Tanner have now
been conducting this spacewalk for two
hours in two minutes they began at 9:45
p.m. Central time 10:45 last night
Eastern Time
okay
working successfully and I'd say you
graduated with honors and also Devin
Taylor who picked up after him I'll bet
they'd support this is an excellent tool
and Houston discovery stated you are is
installed
we'll give you know I have this test go
after these fasteners are on say T 1
copy Steve
we just got a note from Tim Allen up
here Tim Allen dick to be exact and Fox
has been on the home improvement several
times and as we go around the different
centers were known as there's the
astronauts and a guy from
home-improvement all we've had a couple
of terms that they use all the time on
home improvement with the best
description of what we've done to the
Hubble Space Telescope and while we've
accomplished is that we've rewired it
and we've added
and that scientific power we didn't we
didn't jumpstart the solar arrays or
anything like that and so just in
closing you know thanks a lot to
everybody one more time
gear is down and locked
main gear touchdown
nose gear touchdown discovery rolling
out on runway one-five at the Kennedy
Space Center completing 150 orbits
traveling 4.1 million miles ending the
second sub servicing mission to the
Hubble Space Telescope
