Discovery had four landing opportunities
on 9/20/94, two in Florida and two at Edwards Air Force Base, Calif.
The Florida opportunity was waived off due to low clouds and
precipitation near the
Shuttle Landing Facility. A KSC landing would
have involved a deorbit engine
firing at 12:11 p.m. CDT, on the
flight's 174th orbit, followed by a touchdown at 1:11 p.m. CDT. A

Next Mission STS-68
- On Saturday, September 10, 1994 at 9 a.m. CST, it was
reported: Payload activities on board the Space Shuttle
as the STS-64 crew began its
second day in orbit. Discovery's six
astronauts started Flight Day 2 to a parody of a Beach Boys tune called
"We'll Have Fun, Fun, Fun on the Shuttle," sung by Mach 25.
- Before crew members went to sleep, the Lidar In-space Technology
Experiment, STS-64's primary payload, was activated and reported to be
in good working condition. Experiment controllers reported that they
were receiving "terrific looking returns."
- LITE will be used during the course of the mission to collect
atmospheric data with a laser system to measure clouds, particles in
the atmosphere and the
Earth's surface. This information will help
scientists explain the impact of human activity on the atmosphere.
Lidar, an acronym for light detection and ranging is similar to the
radar commonly used to track everything from airplanes in flight to
thunderstorms. It can be thought of as an optical radar, but instead
of bouncing radio waves off its target, lidar uses short pulses of
laser light. Some of that light reflects tiny particles in the
atmosphere, called aerosols, then back to a telescope aligned with the
laser. By precisely timing the lidar echo and by measuring how much
laser light is received by the telescope, scientists can accurately
determine the location, distribution and nature of the particle. The
result is a revolutionary new tool for studying the composition of

- On Saturday, Sept 10, 1994 at 4:30 p.m. CST,
Report: Discovery's crew began
its first full day in orbit with an
assortment of experiments aboard the shuttle. Following a good
performance checkout last night, the Lidar in Space Technology
Experiment (LITE) completed three orbits of nightime observations
above the eastern hemisphere.
- LITE took laser measurements of aerosols above northern Europe,
clouds above Indonesia and the south Pacific, and the surface of the
Himalayan Mountains. Simultaneous atmospheric measurements were
performed by LITE in orbit and by researchers on the ground of the
atmosphere above Tomsk, Russia, a site that has long been a part of
various atmospheric studies.
- Also early today, Mission Specialist
Susan J. Helms performed a check
mechanical arm, finding it to be in excellent
condition. Helms then grappled the Shuttle Plume Impingement Flight
Experiment, a 32-foot long extension to the mechanical arm, raising it
above Discovery's cargo bay. During
SPIFEX activation, flight
controllers noticed a
communications problem with the interface
between Discovery's payload general
support computers and the data
system on SPIFEX. After cycling a circuit breaker that powers the data
were restored and SPIFEX is operating properly.
Later, cold nitrogen gas was fired at SPIFEX to calibrate sensors
which will be used to study the effects of the shuttle's reaction
control system jet plumes.
- On Sunday, Sept 11, 1994 at 9 a.m. CST,
STS-64 MCC Status Report # 4
reports: Planning for the third day of
STS-64 went smoothly last night
as flight controllers refined the timeline to enhance today's payload
activities. In general, the changes will allow for additional live
satellite coverage for the Lidar In-Space Technology Experiment
and the Space Plume Impingement Flight Experiment
(SPIFEX), two of
Discovery's primary payloads. LITE controllers have reported that
they are seeing good results thus far. Crew members started their
third day in space at 7:23 a.m. CDT to a parody of the song "My Girl"
called "My World" by Mach 25.
- On Sunday, Sept 11, 1994 at 4 p.m. CST,
Report: Discovery's crew spent the
first half of the mission's third
day continuing an investigation of the exhaust plumes emitted by the
shuttle's steering jets. Using the Shuttle Plume Impingement Flight
Experiment attached to the end of the shuttle' s mechanical arm,
Mission Specialist Susan Helms positioned instruments above steering
jets both at the rear and over the nose of
- Measuring single and dual jet firings, SPIFEX's instruments
characterized the heat and pressure from the jets to help plan for
dockings of the shuttle with the Russia's Mir Space Station and the
International Space Station. Also, Commander Dick Richards and Jerry
Linenger were interviewed by CNN, answering questions about their
mission that had been sent in by CNN viewers.
- For the rest of the day, the focus aboard
Discovery shifted back to
laser observations using the Lidar in Space Technology Experment. LITE
will take three successive orbits of observations during the last part of
the crew's day. The crew also will exercise during the last part of the
day, evaluating a new type of treadmill carried aboard
has been a long-standing portion of shuttle missions as one method for
offsetting the effects of weightlessness on the body.
- On Monday, Sept 12, 1994 at 7 a.m. CST, STS-64 MCC Status Report # 6
Reports: Investigators are describing some of the data takes with the
Lidar In-Space Technology Experiment, or LITE, as "rich" when compared
to measurements taken by ground and aircraft instruments. LITE is the
first use of a "lidar" system in space.
- Information from the Shuttle Plume Impingement Flight Experiment, or
SPIFEX, indicates that all instruments on the 32-foot long extension
of the Discovery's robot arm
are in good health and providing high
quality data. At the end of the days activities, SPIFEX will be
berthed on the starboard side of the payload bay so that the arm will
be available for the deploy and retrieval of the Spartan satellite on
Tuesday. SPIFEX is being used in tests to help engineers characterize
exhaust plumes emitted by the shuttle's steering jets.
- Overnight, the Robot Operated Materials Processing System, or ROMPS,
continued its smooth operations. The first U.S. robotics system to be
used in space, ROMPS transports semiconductor samples from storage
racks to halogen lamp furnaces for heating and cooling.
- The STS-64
crew began its fourth day in space at 6:23 a.m. CDT with the
song "Ace in the Hole" by George Strait.
- On Monday, Sept 12, 1994 at 3 p.m. CDT, STS-64 MCC Status Report # 7
reports: A variety of observations by the Lidar In-space Technology
Experiment (LITE) marked
Discovery's fourth day in orbit, as well as a
few final studies of the shuttle's steering jet exhaust plumes.
- LITE completed observations of smoke in the atmosphere above
portions of South America, the sea surface in the mid-Atlantic, clouds
above Central America, and the upper atmosphere above northern Europe.
Observations by the laser radar were made during both daylight and
night passes. Several precisely targeted observations required
Commander Dick Richards to aim the laser by altering
orientation, while other sites were surveyed by using a slow rocking
to create a sweep with the laser pulses.
- Scientists with LITE are delighted with the information obtained
thus far, and a variety of concurrent measurements by ground
instruments and airborne instruments have been recorded.
- Earlier today, Mission Specialist
Susan J. Helms conducted a few
more tests of exhaust plumes from
Discovery's small jets using SPIFEX,
a 32-foot long instrumented boom grasped by the shuttle's mechanical
arm. However, early in the test session,
communications broke off
between the laptop computer aboard
Discovery and the experiment's
instruments, causing several low-priority studies to be missed. The
communications link was restored prior to latching the experiment back
into its cradle along the right edge of
Discovery's cargo bay.
- SPIFEX has completed the majority of its planned studies, including
all of the studies of heat and pressures from the jet exhausts that
were deemed to be a high priority for the experiment. The information
will assist in planning future dockings between the shuttle and space
- At 6:03 p.m. CDT today, Commander
Richard N. Richards, along with
Carl J. Meade and Mark C. Lee, the two astronauts
who plan to conduct
a spacewalk later in the flight, will be interviewed by a reporter for
Space News. The interview will be carried live on NASA TV. The crew
will begin an eight-hour sleep period at 10:23 p.m. central and awaken
at 6:23 a.m. Tuesday.
- On Tuesday, Sept 13, 1994 at 8 a.m. CDT, STS-64 MCC Status Report # 8
reports: The STS-64 crew
today prepared to release the Spartan-201
satellite which is expected to spend about 40 hours flying free of
Discovery as it collects information on the Sun and its solar winds.
Following deployment, the
orbiter will perform three separation burns
to move it away from Spartan to a station-keeping point about 50 miles
behind. Spartan-201 will then begin its mission to look for evidence
explaining how the solar wind is generated by the Sun.
- The solar wind originates in the corona, the outermost atmosphere of
the Sun. Spartan-201- carries two separate telescopes to study the
corona. The White Light Coronagraph measures density distribution of
electrons making up the corona. The other telescope, the Ultraviolet
Coronal Spectrometer investigates the temperatures and distribution of
protons and hydrogen atoms through the layers of the corona. This
information, which will be recorded on board the satellite and
retrieved after landing, will help scientists characterize this part
of the Sun. Spartan will be retrieved on Thursday to be berthed once
again in Discovery's
payload bay for the return home.
- Overnight, the Robot Operated Materials Processing System continued
to processes semiconductor samples. Fifty-four of the 100 ROMPS
samples have been processed, and controllers are pleased with the
system's performance so far.
- Crew members began their fifth day in space at 6:23 a.m. CDT with a
parody of the Beach Boys song "I Get Around" called "We Orbit Round"
by Mach 25. The astronauts' efforts to conserve
fuels are paying off. Flight controllers in Houston say the outlook
for an additional day in space is promising.
- On Tuesday, Sept 13, 1994 at 8 p.m. CDT, MCC Status Report # 9
reports: Discovery's crew was given a
go to stay in space an
additional day prior to the checkout and deployment of a science
satellite designed to study the Sun's corona. Later, the crew
continued work with a laser instrument to measure the
atmosphere and cloud cover.
- Mission managers gave the go ahead to extend the mission after evaluating
electrical power usage thus far. The latest margins showed electrical
power consumption is running below pre-flight predictions to provide
enough hydrogen and oxygen to permit an extra day of science data
gathering. The STS-64
mission now is scheduled to conclude with a
landing September 19 in the early afternoon.
- The Spartan satellite was released from
Discovery's robot arm at 4:30
Tuesday afternoon followed closely by three separation maneuvers to
slowly move the
Orbiter away from
SPARTAN to a station-keeping point
about 50 miles behind. Two orbits after release, the satellite began its
mission searching for evidence explaining how the solar wind is generated
by the Sun. SPARTAN will be retrieved on Thursday to be berthed once
again in Discovery's
payload bay for the return home.
- After the deploy, the six crew members began preparations for
continued work with the primary payload aboard the
orbiter -- LITE.
The laser device bounces off of the
Earth's clouds and atmosphere
providing real- time data on the environment and the effects of human

will continue to process semiconductor samples in canisters mounted on
the side of the payload bay. The operation is conducted remotely
while the crew sleeps.
Discovery's crew will go to sleep shortly
before 10:30 this evening and wake up tomorrow morning at 6:23 to
begin checkout of spacesuit equipment to be used during Friday's
- On Wednesday, Sept 14, 1994 at 7 a.m. CDT, STS-64 MCC Status Report # 10
reports: Crew members began their sixth day in space with the song "On
Orbit," sung by Mach 25 to the Green Acres theme. Following the
completion of post-sleep activities, Mission Specialists Carl Meade
and Mark Lee will begin checking out the space suits they will use
during Friday's extravehicular activity.
- The six-hour space walk, currently scheduled to begin at about 9:45
a.m. Central Friday, is designed to test several tools and techniques
that may be used at the International Space Station. Among the tools
is the Simplified Aid for EVA Rescue, or SAFER, a small,
self-contained, propulsive backpack that can provide a free-flying
astronaut control and mobility. SAFER is designed for self-rescue use
by a space walker in the event the shuttle is unable or unavailable to
retrieve a detached, drifting crew member.
- Science activities with the Lidar In-Space Technology Experiment,
or LITE, continued with three data takes. The science activities in
space are being coordinated with concurrent activities on the ground.
Tuesday, 10 different groups from Japan, China, Puerto Rico and the
United States took measurements of the
Earth's atmosphere from the
ground at the same time LITE was recording data in space.
- SPARTAN-201 is moving out ahead of
Discovery, opening at a rate of
3.6 n.m. per hour. Later today, the crew will start maneuvering the
orbiter back toward the science satellite, setting up for its
retrieval on Thursday. Overnight, flight controllers looked at the
data from Discovery's rendezvous radar
which was recording
questionable readings during the deploy operations. Controllers have
concluded that the signatures were the result of the radar's late
acquisition of the satellite, the cause of which is still being
- The Robot Operated Materials Processing System, or ROMPS, also
continues to process semiconductor samples in canisters mounted on the
side of the payload bay. The operation, conducted remotely while the
crew sleeps, is being characterized by its controllers as "very
successful." So far, 74 of the 100 samples have been processed..
- On Wednesday, Sept 14, 1994 at 5 p.m. CDT, STS-64 MCC Status Report # 11
reports: Discovery's crew on Wednesday checked
out equipment that
will be used during an untethered spacewalk on Friday; continued work
in support of laser mapping of clouds, atmospheric and environmental
conditions; and began the process of catching up with a science
satellite which has been operating free of the
Orbiter for two days.
- The two spacesuits were checked out by
astronauts Mark Lee, Carl
Meade and Jerry Linenger and are ready to support the spacewalk on
Friday. They also tested the small jet pack that will be used to fly
free of the Shuttle without tethers for the first time in 10 years.
Also tested was an electronic checklist that fits on the forearm of
the astronauts to provide computer data on various aspects of the
spacewalk. While Lee and Meade are in the payload bay, Linenger will
assist with the choreography from inside the Shuttle.
- Today, science activities with the Lidar In-Space Technology
Experiment, or LITE, continued with three data takes. The science
activities in space are being coordinated with concurrent activities
on the ground. The astronauts also began targeting
Discovery for a
rendezvous and retrieval of the SPARTAN
satellite deployed Tuesday.
The furthest distance the two reached prior to beginning the
rendezvous was 60 nautical miles. Two small firings of the thruster
jets on the Orbiter were
conducted today and the closing rate was
about one nautical mile per orbit.
- Flight controllers spent the day discussing options for rendezvous
in the event the Orbiter's radar system was unavailable during the
final stages of the rendezvous profile tomorrow. The system did not
lock on to the satellite until about an hour after deploy. The
problem has not yet been explained. The rendezvous options without
the radar system include using the ground navigation data as well as
using Discovery's on board
Though these procedures are
not as precise and would require slightly more
propellant than normal,
margins are adequate to support a "no-radar" rendezvous
and the crew and flight control teams are trained for just such a
- The Robot Operated Materials Processing System
(ROMPS) continues to
process semiconductor samples in canisters mounted on the side of the
payload bay. The operation, conducted remotely while the crew sleeps
has so far processed 78 of the 100 samples planned for the mission.
- On Thursday, Sept 15, 1994 at 7 a.m. CDT, STS-64 MCC Status Report # 12
is slowly closing in on Spartan-201 as the
crew prepares to retrieve the science satellite later today. Spartan-201
was deployed from Discovery's
payload bay Tuesday for about 48 hours of
data collection on the solar wind and the Sun's corona.
- With Spartan's science operations nearing completion, crew members
will fire Discovery's
steering jets several times catch up with the
satellite. Once Spartan is
within the orbiter's each, Mission
Specialist Susan Helms will use the robot arm to grab the satellite
about 3:47 p.m. CDT and secure it in the payload bay for return home.
The information gathered during the free-flying operations will be
analyzed by scientists post flight.
- Later today, space-walking astronauts Carl Meade and Mark Lee will
perform an abbreviated pre-breathing protocol in preparation of
Friday's extravehicular activity. The protocol helps clean nitrogen
from the blood of the EVA astronauts before they venture outside the
crew cabin, thus preventing the condition known as "the bends." At
5:23 a.m., flight controllers awakened crew members with the song
"Hound Dog" by Elvis Presley.
- On Thursday, Sept 15, 1994 at 12 noon CDT, STS-64 MCC Status Report # 13
reports: Discovery is closing in on the Spartan-201
for a capture of the satellite at about 3:47 p.m. central time. Spartan
will have spent a total of almost 48 hours flying free from the shuttle
and performing its observations of the sun.
final approach toward Spartan will begin with a Terminal
Phase Initiation, or TI, burn at about 1:44 p.m., when

Discovery's cabin pressure to 10.2
pounds per square inch as part of preparations for tomorrow's planned
spacewalk by Mark Lee and Carl Meade. The lower pressure, along with
about 25 minutes Lee and Meade spent breathing pure oxygen, assists in
purging nitrogen from the astronauts' bloodstreams to avoid a
condition commonly called the bends when they encounter the 4.3 psi

Astronauts Mark C. Lee and
Carl J. Meade will exit the orbiter's
airlock Friday morning for a
six-hour EVA to test of a device designed as a rescue aid or future
spacewalkers who become untethered while working outside their
spacecraft or space station.
- On Friday, Sept 16, 1994 at 7 a.m. CDT, STS-64 MCC Status Report # 15
reports: Mission Specialists Carl J. Meade and
Mark C. Lee are getting ready
to venture out of Discovery's
crew cabin this morning to spend six
hours testing a new propulsive backpack.
- Called SAFER for Simplified Aid For EVA Rescue, the backpack is designed
for use in the event a crew member inadvertently becomes untethered while
conducting an extravehicular activity. During today's space walk, Meade
and Lee will take turns testing the cap abilities of the unit by
performing four specific test sequences.
- The first sequence gives the operator an opportunity to become
familiar with the device before attempting the other
demonstrations. Once the space walker is familiar with the unit, the
engineering evaluation will begin. For that test, the space walker
will fly several short translational and rotational sequences. Next, a
self-rescue demonstration will take place. In it, one space walker
will stand in the foot restraint at the end of
arm and impart a series of rotations to the SAFER space walker. The
SAFER space walker will then activate the unit's attitude control
system to stop the rotation and fly back to the end of the arm. The
fourth test, a flight qualities evaluation, will have the space walker
fly a precise trajectory that will follow the bent mechanical arm,
demonstrating the kind of precision translation that might be needed
at the International Space Station.
- Preparations for the space walk began shortly after 7 a.m. CDT. At about
8:36 a.m., Meade and Lee will begin a 50-minute period of breathing
pure oxygen in their space suits to cleanse the nitrogen from their blood
before depressurizing the airlock.
The two space walkers will step out
of the airlock at about at 9:43 a.m.

the 28th in the
Space Shuttle program.
- Lee and Meade exited the airlock
mid-morning Friday and conducted
several tests of the SAFER, the Simplified Aid for EVA Rescue, while
untethered in Discovery's cargo bay.
Astronaut Jerry Linenger
assisted his crewmates from inside the spacecraft and Susan Helms
maneuvered Discovery's robot arm for the procedures.
- Saturday is the bonus day
on orbit for
STS-64, added when mission
managers determined that onboard supplies were sufficient to get one
more day of science operations. Additional runs are planned of the
Shuttle Plume Impingement Flight Experiment or SPIFEX which looks at
the effect of shuttle jet firings on other space structures, and the
Lidar in Space Technology Experiment or LITE to study the atmosphere.
- On Sunday, Sept 18, 1994 at 3 p.m CDT, STS-64 MCC Status Report # 20

- For Tuesday,
Discovery has four landing opportunities -- two to
Florida early in the afternoon and two to Edwards Air Force Base, Calif., in the
late afternoon. Kennedy Space Center.is the preferred landing site and all
activities will be aimed toward the first opportunity to land at KSC with
deorbit engine firing at 12:12 p.m. CDT,
on the flight's 174th orbit,
followed by a touchdown at 1:12 p.m. CDT. A second opportunity to land in
Florida would begin with a 1:45 p.m. CDT
deorbit burn and result in a 2:45

- The Tuesday forecast for Florida calls for conditions similar to
today's with possible rain showers in the vicinity of the landing
site. If weather again prohibits a landing at KSC Tuesday, flight
controllers will likely attempt a landing in California. The forecast
for Edwards Air Force Base calls for excellent landing weather
- Tuesday's opportunities for landing in California begin with a
Discovery at 3:16 p.m. CDT on the
flight's 176th orbit leading to
a touchdown at 4:13 p.m. CDT at Edwards. A second opportunity would have
