STS-109
Report # 07 
 Sunday, March 3, 2002 - 9 p.m. CST 
 
 The crew of the space shuttle Columbia awoke for its first spacewalking
day in orbit to "Five Variations on Twinkle, Twinkle Little
Star," performed by Jeno Jando.  It was played for John Grunsfeld.
Spacewalkers Grunsfeld and Rick Linnehan will step out into space for the
first time during this mission at about 12:30 a.m. tomorrow morning.  

Within hours of awakening Grunsfeld and Linnehan, with the assistance of
crewmates Jim Newman and Mike Massimino, will begin donning their
spacesuits.  Grunsfeld, performing his third spacewalk, will wear a
spacesuit with red stripes.  Linnehan, who is conducting his first
spacewalk, will be wearing a spacesuit without any stripes. The pair may
work ahead of schedule and leave the airlock as much as an hour earlier
than planned.  

They will begin the spacewalk with about an hour of setup activities in
the payload bay to prepare for the total of five spacewalks for this
mission.  The next scheduled task is to install the new solar array's
electrical support components, called a Diode Box Assembly, on the Hubble
Space Telescope.

Space shuttle robot arm operator, Nancy Currie, will move the
spacewalking duo by providing transportation to and from the worksite at
the starboard array of the telescope.  Grunsfeld, anchored to the
telescope, will prepare the array for removal.  Linnehan, on the end of
the robotic arm, will then hold onto the array as Currie guides the arm
into the payload bay where Linnehan will stow the old array for its
return to Earth.  Linnehan will then return to the worksite to help
install the new solar array.

The third-generation solar arrays are two-thirds the size of the current
arrays but will provide 20 percent more power to the telescope.  Because
of their smaller size, the new arrays will impart less atmospheric drag,
slowing the rate at which Hubble's orbit decays.

Columbia Commander Scott Altman and Pilot Duane Carey will document their
crewmates' work during the spacewalk with television and still-photo
cameras, while also monitoring systems onboard Columbia.  Today's
spacewalk is scheduled to last 6 1/2 hours.

The crew is to begin its sleep period at 11:52 a.m. CST.  The next
STS-109 mission status report will be issued Monday morning or as events
warrant.

STS-109
Report # 08 
 Monday, March 4, 2002 - 12 p.m. CST 
 
 The Hubble Space Telescope has a new starboard solar array after a seven
hour-one minute long spacewalk by Columbia astronauts John Grunsfeld and
Rick Linnehan. 

During the space walk, which began at 12:37 a.m. CST, Grunsfeld and
Linnehan removed the old starboard solar array from Hubble and installed
in its place a new third-generation solar array and its associated Diode
Box Assembly. The old solar array was stored in Columbia’s payload bay
where it will be returned to Earth to allow engineers to determine how it
fared during its nine years in space.  The new arrays are two-thirds the
size of the current arrays but will provide 20 percent more power to the
telescope.  Because of their smaller size, the new arrays also will
impart less atmospheric drag, slowing the rate at which Hubble’s orbit
decays.

Throughout the space walk, Mission Specialist Nancy Currie used the
shuttle’s robotic arm to maneuver the two space walkers around Columbia’s
payload bay and the Hubble telescope. Linnehan was on the arm for most of
the space walk, with Grunsfeld taking his place about five hours and
fifteen minutes into the space walk. 

>From the aft flight deck of Columbia, astronauts Mike Massimino and Jim
Newman assisted the two spacewalkers throughout their numerous tasks.
Newman and Massimino will be performing their first spacewalk of the
mission tomorrow morning, replacing Hubble’s port solar array and a
Reaction Wheel Assembly, one of four devices that help Hubble maintain a
steady position as it photographs distant objects. 

During the spacewalk, Grunsfeld’s EVA suit did not transmit its normal
telemetry signal to the ground, though the Flight Surgeon was able to
monitor the astronaut’s biomedical data. After resetting power to the
suit later following the spacewalk, EVA officers in Mission Control were
able to receive data normally. It is believed a relay in the suit’s
communication system needed to be reset.

The crew is to begin its sleep period at 11:52 a.m. CST.  The next
STS-109 mission status report will be issued Monday morning or as events
warrant.
