14 November 2002 - Evening Update -
Work on the
Shuttle's robotic arm is in progress.
Technicians Replace Leak Source, Arm Evaluation Continues
source of the oxygen leak that delayed the launch of STS-113 -- a faulty
flex hose assembly -- on Sunday has been successfully replaced inside
Space Shuttle Endeavour. The new assembly and Endeavour's bulkhead have
been tested, X-rayed and cleared for flight.
Meanwhile, evaluation continues of the damage that Endeavour's
robot arm sustained during the leak troubleshooting efforts. A team of
robot arm experts arrived at Kennedy Space Center, Fla., Wednesday and are
planning to perform ultrasound testing of the arm. Program managers are
scheduled to meet Friday to discuss the results of the tests and analysis.
The robot arm will be used to lift the P1 (P-One) Truss out of
the payload bay and hand it to its station counterpart, Canadarm2.
14 November - Thursday - With
the oxygen leak
found and fixed,
attention now turns to inspecting Endeavour's robotic arm to see if the
more than cosmetic. NASA is still pushing for a Monday launch.
13 November 2002 - Evening Update - The
inside Endeavour's midbody has been
underway. Unfortunately, the
Shuttle's robotic arm,
"Canadarm" (or officially,
Remote Manipulator System) may have been damaged in the process. The
thermal insulation covering it was torn (easy to patch up), but
damage goes deeper, Endeavour will have to come off the pad for the
arm to be repaired.
The arm is essential to
this mission, and it
cannot support its
own weight in Earth's gravity.
Inspection Finds Leak; Analysis of Robot Arm Damage Under Way
oxygen flex hose fitting was identified as the source of the leak inside
Space Shuttle Endeavour during Tuesday's inspection, and efforts are under
way to replace it. The leak caused managers to postpone STS-113's launch
earlier this week.
Meanwhile, technicians are evaluating damage that the shuttle
robotic arm sustained during leak troubleshooting efforts. A work platform scuffed
the arm, tearing a surface insulation blanket scraping the arm's shell.
An evaluation is under way to determine if the damage will have
any impact on arm operations during STS-113's visit to the International
Space Station. The robot arm will be used to lift the P1 (P-One) Truss out
of the payload bay and hand it to its station counterpart, Canadarm2.
Results of the evaluations, which include ultrasonic checks, are expected
later this week.

13 November 2002 - Wednesday - Last
searching for the leaky
oxygen line in Endeavour's midbody, engineers inadvertently
struck the robot arm's thermal insulation and tore
it. The question is, was
the arm itself damaged? At least there's some good news - the source
of the leak has been found.
12 November 2002 - Evening Update - Pad techs continue their work to
find the leak in
Endeavour's oxygen system.
Technicians to Look for Oxygen Leak Source in Endeavour
night, technicians at Kennedy Space Center, Fla., are scheduled to begin
inspections to locate the source of an oxygen leak inside Space Shuttle
Endeavour. The leak forced managers to delay the launch of STS-113 Sunday
night. Endeavour, which will deliver the P1 (P-One) Truss and the
Expedition Six crew, is now slated to lift off no earlier than Nov. 18.
Meanwhile, workers have completed some turnaround activities.
They have unloaded Endeavour's external fuel tank and removed the liquid
hydrogen and liquid oxygen from the Power Reactant Storage and
Distribution System. Also, the STS-113 crew has returned to Johnson Space
Center in Houston, Texas.
The exact launch time will be kept secret for security purposes, but will
be between 7PM and 11PM EST Monday. Press conference video

12 November 2002 - Tuesday -
Pad workers spent
Monday unloading fuel from the Shuttle,
and will attempt to

having to remove the cargo - the $390-million
P1 Truss, which was
bound for the International Space Station early
morning when the countdown was
suddenly stopped. NASA officials are
hopeful that a

11 November 2002 - Veteran's Day - Last night (or
this morning, depending on your time zone), Shuttle Manager
Ron Dittemore announced a
one-week delay in
Endeavour's launch to

Leak Forces STS-113 Launch
An oxygen leak inside Space Shuttle Endeavour forced managers to
delay the launch of STS-113 on Sunday. The leak is in a system that
supplies oxygen to the crewmembers after they lower their visors just
before launch and supplies oxygen to the crew cabin while the shuttle is
in orbit. The leak is located in Endeavour's midbody below the payload bay.
support personnel will continue troubleshooting efforts. STS-113 is now
scheduled to launch no earlier than Nov. 18.
for the engines and
power systems will be drained from the Shuttle today, and techs should be able to start looking for the leak on
Wednesday. The crew, who were getting aboard Endeavour when the scrub was
called, will return home to Houston for the week.
10 November 2002 - Midnight Update - OK,
more scoop: Ground personnel are going to have to
get into the guts of Endeavour to
source of the
O2 leak - and it
remains to be seen whether the P1 Truss will have to be removed from the Payload Bay.
Managers Delay STS-113 Launch Delay Due to Leak
oxygen line leak inside Space Shuttle Endeavour forced managers to delay
the launch of STS-113 by at least 24 hours. They are still assessing the
situation and will announce a new launch date later.
STS-113 will be the 16th shuttle mission to visit the orbital
outpost. Endeavour will deliver the Expedition Six crew and the P1 (P-One)
Truss to the station. The STS-113 crew will perform three spacewalks to
outfit and install the P1 after it is attached to the station on Flight
Day 4. The station's current residents, the Expedition Five crew, will
return to Earth with Endeavour.
Launch was scrubbed about
2 hours before the Shuttle was to roar into orbit.
So far, the just-announced date is Nov 18th - a one-week delay.
10 November 2002 - Sunday - SCRUB! - As of about 9:45PM
EST, launch is postponed for at least one day!
Leak Forces STS-113 Launch Delay
NASA managers postponed the launch of Space Shuttle Endeavour for at least 24
hours to allow time to troubleshoot an oxygen leak in the lines from the
midbody leading to the crew compartment.
Turnaround options are being discussed. Stay tuned for further
information as it becomes available.
More info will be provided as we get it...
