- The primary mission objectives for STS-101 is to deliver supplies to
the International Space Station, perform a spacewalk and then reboost
the station from 230 statute miles to 250 statute miles.
- Detailed objectives include ISS ingress/safety to take air samples,
monitor carbon dioxide, deploy portable, personal fans, measure air
flow, rework/modify ISS ducting, replace air filters, replace Zarya
fire extinguishers and smoke detectors. Critical replacements, repairs
and spares will also be done to replace four suspect batteries on
Zarya, replace failed or suspect electronics for Zarya's batteries,
replace Radio Telemetry System memory unit, replace port early
communications antenna, replace Radio Frequency Power Distribution Box
and clear Space Vision System target.
- The mission also includes incremental assembly/upgrades such as
assembly of Strela crane, installation of additional exterior
handrails, set up of center-line camera cable, installation of
"Komparus" cable inserts and reseating the U.S. crane. Assembly
parts, tools and equipment will also be transfered to the station and
equipment stowed for future missions.
- The station will also be resuppled with water, a docking mechanism
accessory kit, film and video tape for documentation, office supplies
and personal items. Crew health maintenance items will also be
transfered including exercise equipment, medical support supplies,
formaldehyde monitor kit and a passive dosimetry system.
- If there is sufficient shuttle propellant followingAtlantis'
undocking from the ISS, a flyaround inspection will be performed prior
to the Shuttle's final separation maneuver.
- Launch May 19, 2000 6:11 a.m. EDT. Launch window was 5 min
- On Friday, May 19, 2000 1:12 a.m. EDT, the crew had their pre-flight
snack in the Operations and Checkout Building. At 2:20 a.m EDT, they
departed the Operations and Checkout Building (O&C) for Launch Pad
39-A. By 3:40 a.m. EDT, all communication checks between the Atlantis
and the ground were completed and at 3:56 a.m. EDT, the hatch was
closed and locked for flight. At 4:48 a.m. the white room crew
closeout was complete and the closeout crew departed for the
fallback area. Launched ontime at the opening of the window.
- On Wednesday, May 17, 2000, launch controllers added 23 1/2 hours to
the launch count at the T-11 hour built-in hold, slipping the launch
of Shuttle Atlantis to Friday at about 6:12 a.m. The decision followed
a Tuesday evening postponement of the Air Force Atlas III launch and
was part of an preplanned agreement between NASA and the Air Force.
The Rotating Service Structure at the pad will move away from the
vehicle at about 10 a.m. on Thursday. Loading of the external tank
with more than 500,000 gallons of liquid propellant begins at about
8:47 p.m. 5/18/2000. (Reference KSC Shuttle Status 5/17/2000)
- On Tuesday, May 16, 2000, the launch date was rescheduled for
Friday, May 19th, due to the scrub of the Atlas III/EUTELSAT launch.
- On Monday, May 15, 2000, the countdown clock picked up the count at
the T-43 hour mark at 9:30 a.m. The seven member flight crew arrived
at KSC on Sunday, May 14, 2000. (Reference KSC Shuttle Status 5/10/2000)
- At 6:03 a.m. EDT on Wednesday April 26, fueling of the external tank
began for the 3rd consecutive launch attempt and was completed at the
T-minus 3 hour 20 minute mark at 9:11 a.m. EDT. At 9:31 a.m. EDT a
red repair team was sent to the launch pad to restore redundancy to a
heater system located in the base of the pad used to recirculate air
as part of the liquid oxygen gaseous vent arm system. The crew
replaced a blown fuse. At 10:29 a.m. EDT the crew sat down for a crew
breakfast in the O&C building and prepared for a weather briefing. At
11:13 a.m. EDT, the weather briefing concluded with favorable weather
forcasted at the launch site but marginal weather forcasted at the
contigency landing sites. At 11:14 a.m. EDT, the crew began suit up
operations. At 11:39 a.m. EDT, the crew departed the astronauts
quarters and left for launch pad 39A. By 2:06 p.m. EDT the crew were
all in their seats, the hatch closed and comm checks complete. At
2:24pm EDT (18:24 GMT) the countdown clock came out of the hold at the
T-minus 20 minute mark and counted down to T-minus 9 minutes and
holding. The mission management team was polled and the only issue
being tracked was weather concerns at the TAL sites. During the hold
at the T-minus 9 minute mark, the mission management team decided to
scrub the 3:29 pm launch attempt for 4/26/2000 due to weather
constraints at the TAL sites.
- At 6:30 a.m. on April 25, 2000, fueling of the external tank began
in order to support a launch attempt at 3:52 pm. Communication checks
were complete with the crew at 1:16pm EDT. At 1:24pm EDT a go was
given to close the hatch. At 2:18pm EDT, at the T-minus 38 minute
mark, Launch director Dave King called a scrub due to high winds at
the SLS and launch pad. The launch team was told to prepare for a 24
hour scrub turnaround.
- At 4:07 p.m. the call was given to scrub the launch attempt for April
24, 2000, because of a cross wind violation at the Shuttle Landing
Facility (SLF). A weather briefing will be conducting in order to
determine if a 24, or a 48 hour scrub turn around would offer better
weather conditions for the next launch attempt.
- At 2:04 pm on Monday, April 24, 2000. The hatch to Atlantis was
closed in preparation for an on time launch at 4:15 PM EDT. The launch
window is 5 minutes and 2 seconds. Therefore, the last opportunity for
launch today will be at 4:22:19pm EDT.
- On Wednesday, April 19, 2000. Prelaunch processing efforts are
going well at Launch Pad 39A. Ordnance installation and preliminary
tests are complete. Last night, workers replaced two quick disconnects
on gaseous nitrogen lines for auxiliary power units (APU) No. 1 and
No. 2. The APU flight pressurization tests are complete and
good. Pressure tests on the orbiter's reaction control system are also
complete. Orbiter aft engine compartment close-outs are ongoing and
managers expect the aft doors to be installed Friday. Launch
controllers continue countdown preparations in the Launch Control
Center. The crew arrives April 21 at 3 p.m. EDT and launch countdown
begins at 7 p.m. on the same day.
- (Reference KSC Shuttle Status 4/19/2000)
- Over the weekend (April 15-16,2000), Shuttle engineers completed the
frequency response test that was required after the rudder/speed brake
power drive unit replacement effort. Preliminary evaluation indicates
that Shuttle Atlantis' hydraulic system is operating normally and that
the PDU replacement was a success. Shuttle engineers continue to
analyze the cause of the initial PDU failure to ensure that it was an
isolated incident. At about 1 a.m. today, engineers completed a hot
fire test of auxiliary power unit (APU) No. 1 confirming a successful
hydraulic flex hose replacement. Tomorrow, technicians will also
replace a quick disconnect located on an APU No. 2 gaseous nitrogen
line. All three APUs will be brought up to flight pressure on
Wednesday as part of standard prelaunch testing.
- (Reference KSC Shuttle Status 4/17/2000)
- On Wednesday, March 29, 2000, program managers have selected April 24
as the target launch date for STS-101. This one-week delay will allow
Mission Commander Jim Halsell to complete planned training activities,
primarily T-38 and Shuttle Training Aircraft flights, which were
delayed due to an ankle injury that occurred on March 15. Today's
decision, made at the request of Halsell's management, provides
additional time to complete that training prior to the scheduled
launch. Halsell's recovery from what was termed a "moderate sprain"
has been proceeding on or ahead of schedule. He will be evaluated for
T-38 and Shuttle Training Aircraft flight status next week.
(Reference KSC Shuttle Status 3/29/2000)
- On Saturday, March 25, 2000, Shuttle Discovery was rolled out of the
Vehicle Assembly Building to Launch Pad 39A. Main engine No. 1 leak
checks are complete and the Flight Readiness Test is in work
today. The Terminal Countdown Demonstration Test at KSC remains
targeted for April 6 and 7.
(Reference KSC Shuttle Status 3/29/2000)
- On Friday, February 18, 2000, Atlantis' main propulsion system leak
checks are complete. Today work began to install the transfer tunnel
adapter in the orbiter's payload bay. Orbiter electrical wiring
inspection, repair and protection continue. Managers named a modified
STS-101 crew today to prepare the space station for the arrival of the
Zvezda service module. The STS-101 crew includes Commander Jim
Halsell, Pilot Scott Horowitz, and Mission Specialists Mary Ellen
Weber, Jeffrey Williams, James Voss, Susan Helms and Yuri Usachev.
Edward Tsang Lu, Yuri Ivanovich Malenchenko, and Boris Morukov had
previously been assigned to the mission.
(Reference KSC Shuttle Status 2/18/2000)
- On Wednesday, January 26, 2000, This week, technicians removed a
thruster from Atlantis' orbiter maneuvering system and installation of
the new thruster is under way. Ammonia system leak and functional
testing continues. Orbiter fuel cell tests are also ongoing. Wiring
inspections and repairs continue in the orbiter's aft and midbody
compartments. (Reference KSC Shuttle Status 1/26/2000)
- On Friday, October 29, 1999, Shuttle managers announced that the
launch of Space Shuttle Atlantis on mission STS-101 will occur no
earlier than March 16. The wiring inspections and repair efforts that
remaining on the orbiter, along with the unplanned replacement of the
ammonia boiler will require time to accommodate the Shuttle's
processing needs. Inspections of Atlantis' ammonia boiler this week
revealed corrosion, which lead to the replacement decision.
Evaluation of the orbiter's damaged elevons continues. The damaged
parts will be replaced over the next several days with no additional
impact to the schedule. Installation of the right hand orbital
maneuvering system pod occurs this week
(Reference KSC Shuttle Status 10/29/1999)
- On Thursday, October 7, 1999, with wiring inspections and repairs
of Discovery andEndeavour nearing completion and similar work beginning
on Atlantis, Shuttle program managers set new planning target launch
dates for the next three Space Shuttle missions.
