is the fifth of nine planned missions to
Mir and the
second one involving an exchange of U.S. astronauts. Astronaut
who has been on Mir since September 19, 1996, will be
replaced by astronaut Jerry Linenger.
Linenger will spend more
than four months on Mir.
He will return to Earth on Space Shuttle
STS-84, scheduled for launch in May 1997.
Atlantis will carry the
SPACEHAB double module providing
additional middeck locker space for secondary experiments. During the
five days of docked operations with
Mir, the crews will transfer water
and supplies from one spacecraft to the other. A spacewalk by
Linenger and one of his Russian cosmonaut crewmates will be after
STS-81 mission also will include
several experiments in
the fields of advanced technology,
Earth sciences, fundamental
biology, human life sciences, microgravity, and space sciences.
Data also will supply insight for the planning and development of
the International Space Station,
Earth-based sciences of human and
biological processes, and the advancement of commercial
STS-81 will involve the transfer of
5,975 pounds of logistics
to and from the Mir, the largest transfer of items to date.
During the docked phase, 1,400 pounds of water, 1,137.7 pounds of
U.S. science equipment, 2,206.1 pounds of Russian logistics along
with 268.2 pounds of miscellaneous material will be transferred to
Mir. Returning to Earth aboard
Atlantis will be 1,256.6 pounds of
U.S. science material, 891.8 pounds of Russian logistics and 214.6
pounds of miscellaneous material.
- Launch 1/12/97 4:27:23.042 am EST. The launch window was 7-10
minutes. The exact launch time was announced about 90 minutes prior
to launch following final computation of the location of the
Station. The RSRM

Solid Rocket Boosters (SRB's) were
successfully seperated from the

Space Shuttle Main Engine
(SSME) cutoff occured at 511.8 sec.
- On 1/10/97, Pad 39-B was cleared to
load the onboard cryogenic
tanks and reactant loading was completed on schedule by mid-morning.
launch team evaluated a problem with the hazardous gas
detection system on the
Mobile Launcher Platform
(MLP). The system,
used to detect the levels of gaseous oxygen, hydrogen, helium and
argon on the shuttle was giving erratic data.
- On 1/7/97, ordnance operations and pressurization of the
Reaction Control System
(RCS) were completed. Final stowage of
experiments in the SPACEHAB were underway. The
STS-81 crew arrived
at the Shuttle Landing Facility at 10p.m. on 1/8/97 and the
countdown clock picked up at the
T-43 hour mark on schedule on
Thursday, 1/9/97 at 7 a.m.
- On 1/3/97, All Space Shuttle Main Engine
(SSME) functional tests
were complete. The payload bay doors
were open and payload operation
Functional tests on Atlantis's C-hatch (EVA hatch)
were completed and the hatch closed for flight.
- On 12/17/96, The
STS-81 crew successfully completed the Terminal
Countdown Demonstration Test and returned to their homes in Houston.
Inertial Measurement Unit
(IMU) calibrations were also completed and
the pad was closed for normal access as work began on the loading of
hypergolic propellants into
Atlantis. Once the pad is opened again,
efforts will resume to complete the installation and functional checks
of the newly reworked
airlock hatch actuators
that failed on STS-80.
All actuators will be installed by 12/21/96 and functional checks
completed by 12/24/96.
- On 11/22/96, the new replacement fuel cell No. 2 has been installed
and interface connections and testing will be conducted 11/23/96. The
payload bay doors are scheduled to be closed as early as Monday
night. External tank and solid rocket
booster close-outs continue in
the Vehicle Assembly Building.
- On 11/20/96, removal of fuel cell No. 1 was complete. Due to concerns
with marginal pH levels, managers have decided to remove and replace
fuel cell No. 2, as well. Today, managers are determining if this
work can be done with the SPACEHAB tunnel adapter in place or if the
tunnel must be removed.
- On 10/11/96,
APU installation was complete.
Orbital Maneuvering System
pod functional checkout and fuel cell voltage tests were in work. Close
outs continued on the mated left
aft and left forward center segments of
STS-81's SRB stack in
VAB hi-bay 1.

Shuttle Landing Facility
Runway 33. Main gear touchdown at 9:22:44 EST (MET 10days 4hr 55min 21sec).
Nose gear touchdown at 9:22:55 (MET 10days 4hours 55min 32sec) and
Wheel Stop at 9:23:50. (MET 10days 4hours 56min 30sec).
- There were two landing opportunities for
Atlantis on 1/22/97 at the
Kennedy Space Center.
KSC's 1st opportunity would have required a
deorbit burn at 5:42 a.m. CST with a landing at a 6:47 a.m. landing on
runway 3-3 but that opportunity was waived off due to weather. KSC's
2nd opportunity was selected and a 3.5 min
deorbit burn occured at
8:17am EST on orbit 160.
