- The STS-74 mission is the second of seven planned Space
Shuttle-Mir link-ups between 1995 and 1997, including rendezvous and
docking and crew transfers, which will pave the way toward assembly of
the international Space Station beginning in November 1997. Major
objectives include docking with the Mir space station and delivery of
a Russian docking module and 2 solar arrays.
- This mission marks the first time astronauts from the
European Space Agency, Canada, Russia and the U.S will be in
space on the same complex at one time -- a prime example of
nations that will be represented on the international Space
- Atlantis will carry the Russian-built Docking Module,
which has multi-mission androgynous docking mechanisms at
top and bottom. During the flight to Mir, the crew will use
the Orbiter's Remote Manipulator System robot arm to hoist
the Docking Module from the payload bay and berth its bottom
androgynous unit atop Atlantis' Orbiter Docking System.
Atlantis will then dock to Kristall using the Docking
Module's top androgynous unit. After three days, Atlantis
will undock from the Docking Module's bottom androgynous
unit and leave the Docking Module permanently docked to
Kristall, where it will provide clearance between the
Shuttle and Mir's solar arrays during subsequent dockings.
- Atlantis will deliver water, supplies, and equipment,
including two new solar arrays -- one Russian and one
jointly-developed -- to upgrade the Mir. It will return to
Earth experiment samples, equipment for repair and analysis
and products manufactured on the station.
- Also flying aboard Atlantis is the GPP payload
consisting of two experiments -- the GPP experiment and
the Photogrammetric Appendage Structural Dynamics Experiment
(PASDE). The payload is managed by Goddard Space Flight
Center's Special Payloads Division.
- The GPP will study the Earth's thermosphere,
ionosphere and mesosphere energetics and dynamics using
broadband spectroscopy. GPP also will study spacecraft
interactions with the atmosphere by observing Shuttle and
Mir glow, Shuttle engine firings, water dumps and fuel cell
- Three PASDE cannisters, located throughout the cargo
bay, will photogrammetrically record structural response
data of the Mir solar arrays during the docked phase of the
mission. These data will be analyzed on the ground to
verify the use of photogrammetric techniques to characterize
the structural dynamics of the array, thus demonstrating
that this technology can result in cost and risk reduction
for the international Space Station on-orbit structural
- Atlantis will also carry back to earth the University of
California at Berkeley Trek Experiment which has been in orbit
onboard Mir for the past four years.
- Launch November 12, 1995 at 7:30:43.071 A.M. EST. Launch Window was
10 min 09 sec but Atlantis lifted off at the begining of the window.
There were no unscheduled holds. Winds at liftoff were from
approximately 289 degrees at 6.7 knots; the ambient temperature was 50
degrees F, the barometric pressure was 30.06in Hg; and the relative
humidity was 82%. Transatlantic Abort Landing (TAL) sites were
Zaragoza, Spain for primary and Moron, Spain and Ben Guerir, Morocco
as alternates. White Room close out completed at 6:18am EST. At
7:12am EST the mission management team was polled and all stations
were "go for launch" except SRO. Weather constraint, cloud ceiling below
6000ft for RTLS abort. (Reference KSC Weather History 11/12/1995 0700).
Range cleared for launch at 7:20am EST. Main Engines cutoff at 7:39am EST.
- Launch attempt on November 11, 1995 at 7:56am EST was scrubbed due
to poor weather at the Transatlantic Abort (TAL) Site. A scrub due to
a TAL site has only occured once before on 1/9/86 for Columbia's
launch attempt on mission STS-61C. The mission management team decided
to enter a 24 hour scrub turnaround and attempt a launch on
11/12/95. Launch Window was 6 min 57 and the countdown had begun
on schedule. The crew was onboard when the scrub was called at
the T-minus 5 minute mark at approximately 7:51am EST.
- On 11/09/95, Pad 39-A was cleared to load the onboard cryogenic tanks
with liquid hydrogen and liquid oxygen reactants. Reactant loading has been
completed. The reactants will provide electricity for the orbiter and crew
while in space and drinking water as a by-product during their 8-day
mission. (Reference KSC Shuttle Status 11/09/1995).
- On 11/07/95, Engineers have determined no additional work is required
to verify the readiness for flight of the STS-74 solid rocket boosters
in light of extremely small cracks found on hold-down posts
attached to other boosters that flew earlier this year. Previous
inspections on the boosters at the pad indicate no cracking is
present. Mission managers will be fully briefed on the matter at the
scheduled management team meeting to be held at KSC on Thursday.
(Reference KSC Shuttle Status 11/07/1995).
- On 9/05/95, Main engine (SSME) installation was completed in OPF Bay 2
and the Russian MIR-2 Docking Module closeout operations were completed
in the Operations and Checkout Building. (Reference KSC Shuttle Status 9/05/1995).
- On 8/25/95, three thrusters on the right hand OMS pod were replaced
in the OPF (Reference KSC Shuttle Status 8/25/1995).

- KSC November 20, 1995 at 12:01:27 pm EST on Runway 33. Deorbit burn
was done on orbit 128 at approximately 11:00am EST. Dual sonic booms
heard in the KSC Industrial area at 11:58:30am EST. Main Landing Gear
touched down at the KSC Shuttle Landing Facility at a Mission Elapsed
Time of 8 days 4 hours 20 minutes and 44 seconds (12:01:27 EST).
Nose Gear touched down at 8 days 4 hours 30 min 54 seconds (12:01:37 EST)
and wheels stopped at an MET of 8 days 4 hours 31 min 42 sec (12:02:24 EST).
(Reference KSC Shuttle Status 11/20/1995). Weather was acceptable for landing
(Reference KSC Weather History 11/20/1995 1200).
- A second opportunity existed but wasn't necessary for a KSC landing
at 1:37pm EST with a deorbit burn at 12:36p.m. on orbit 129.
