he Landsat-4 and-5 data presented at the press briefing yesterday regarding
ropical deforestation and adverse effects on tropical forest habitat indicates
hat in the period between 1978-88, the extent of deforestation in the
razilian Amazon Basin was less than expected. However, deforestation did
ncrease substantially and created adverse "edge effects" that pose a
ubstantial threat to the habitat of plant and animal species.
he study shows that during the period, the rate of deforestation in the
razilian Amazon Basin was 6,000 square mile (15,000 square kilometers) per
ear. The results from this study, which was conducted by the Goddard Space
light Center and the University of New Hampshire, is published in today's

hursday, June 24, 1993, 3:30 p.m. CDT
ndeavour's crew captured and stowed the EURECA satellite at 11:36 a.m. CDT
oday when the payload retention latches and keel latch locked down onto the
pecial berthing platform in the aft cargo bay.
he European Retrievable Carrier's two solar panels retracted and latched into
lace as planned. But, EURECA ground controllers could not get the two radio
ntennas completely into position for a positive latch indication. The number
ne antenna was about four degrees from complete retraction and the number two
ntenna was two degrees from its stowed position. After an additional attempt
o drive both latch motors in the primary and redundant modes, payload
ontrollers and the Mission Control team decided to berth the satellite with
he antennas unlatched. The remotely operated electrical umbilical was locked
nto place at 11:42 a.m. CDT. The umbilical supplies electricity from
ndeavour's fuel cells to the EURECA satellite's thermal control units to keep
nstrument temperatures at the proper levels.
he EURECA payload controllers and Mission Control teams are refining three
ptions to latch down the two EURECA antennas. The first option calls for the
wo spacewalking astronauts, David Low and Jeff Wisoff, to manually hold down
he antenna booms while EURECA controllers send computer commands to drive the
atches closed. The second option would have the astronauts tie down the
ntenna booms to the main satellite structure. The third option has the
pacewalkers removing the two antennas from the satellite and stowing them
nside Endeavour's crew cabin at the end of the spacewalk.
uring the crew's sleep period tonight, the Planning Team will refine the
etails of the three options for a final decision before the spacewalk begins
t 8 a.m. CDT Friday.
anice Voss wrapped up the Spacehab module experiments for Thursday a few
inutes after 2 p.m. CDT.
ndeavour circles the Earth every 94 minutes in a near-circular orbit with a
igh point of 260 nautical miles and a low point of 255 nautical miles.

reparations for a space walk planned to start at 8:02 a.m. central time today
ave been progressing smoothly aboard Endeavour.
stronauts David Low and Jeff Wisoff will spend about 40 minutes of their five
ours outside working to secure two antennas on the European Retrievable
arrier satellite retrieved by the shuttle yesterday. Remote commands during
he retrieval to retract the antennas did not fold them fully, against the
URECA satellite. Standing on a platform at the end of the shuttle's robot
rm, Low will push each antenna to the fully folded position so that latches
an be remotely closed to hold them secure during Endeavour's return to Earth.
f the latches won't close, then the space walkers will lash the antennas in
lace with straps carried aboard Endeavour.
fter the antennas are secured, the remaining four hours of space walking will
e spent as planned prior to the flight. Low and Wisoff will perform
valuations of moving and aligning large objects while standing at the end of
ndeavour's robot arm, evaluate how well a space walker must be restrained to
erform work such as tightening a bolt, and evaluate general mobility.
uring the space walk, Mission Specialist Nancy Sherlock will control
ndeavour's mechanical arm from the aft cockpit. Low and Wisoff began
reathing pure oxygen inside their spacesuits four hours before the spacewalk,
urging nitrogen from their bodies to prevent a condition commonly called the
ends. Upcoming activities include the beginning of depressurizing Endeavour's
irlock about 7:42 a.m. central; the EURECA antenna securing to start at about
:57 a.m.; and the conclusion of the space walk about 1:02 p.m.
he crew was awakened at 12:07 a.m. central today by the Dire Straits' song
Walk of Life," played by Mission Control in honor of the upcoming space walk.
arly this morning, Commander Ron Grabe fired Endeavour's large orbital
aneuvering system engines to drop the low point of the shuttle's orbit by
bout 45 nautical miles and enhance the landing opportunities that will be
vailable at the end of the mission. Endeavour is now in an orbit with a high
oint of 256 nautical miles and a low point of 210 nautical miles, circling
arth each 93 minutes.

he European Retrievable Carrier's dual antennas are safely latched against the
cience satellite following a spacewalk by Mission Specialists David Low and
eff Wisoff.
t the beginning of the five-hour, 50-minute extravehicular activity, David Low
ounted an foot restraint on the end of Endeavour's robotic arm. Mission
pecialist Nancy Sherlock then positioned the arm so Low could gently push the
rms against EURECA's latch mechanisms. Payload controllers then drove the
atches to secure each antenna.
ollowing the EURECA work, Low and Wisoff performed several procedures for an
bbreviated EVA Detailed Test Objective. Activities associated with each of the
reas of investigation -- mass handling, mass fine alignment and high torque --
ere completed with both EVA crewmen taking turns on the robot arm. Low and
isoff wrapped up their spacewalk and returned to Endeavour's airlock shortly
efore 3 p.m. Central.
he STS-57 crew will end their fifth day in space with an eight-hour sleep

/25/93: STS-51 PAYLOADS ARRIVE AT LAUNCH PAD FOR NEXT SHUTTLE LAUNCH
eorge H. Diller June 25, 1993
SC Release No. 70-93
Payloads for the next Space Shuttle mission, STS-51, arrived
t Pad 39-B this morning - passing yet another major milestone in
relaunch processing.
Riding in the payload canister atop the associated
ransporter, the Advanced Communications Technology Satellite
ACTS) and the Orbiting Retrievable Far and Extreme Ultraviolet
pectrometer (ORFEUS) began the 15-mile trip from the Vertical
rocessing Facility (VPF) in the KSC Industrial Area at 9 p.m.
ast night. By 1 a.m. this morning, the payloads were at the
ea-side launch pad.
Payload processing team members are busy today installing
he ACTS-TOS and ORFEUS-SPAS into the pad's payload changeout
oom.
ACTS will serve as a test bed for advanced experimental
ommunications satellite concepts and technology. Its Transfer
rbit Stage (TOS) upper stage booster will lift the satellite to
eosynchronous altitude on the first day of the mission.
ORFEUS is a telescope system which will provide information
n how stars are born and how they die, while also studying
aseous interstellar clouds. Its carrier, the Shuttle Pallet
atellite (SPAS), will be deployed from the orbiter for 40 to 60
ours to allow observations during the flight before being
eturned to the payload bay.
Based on a 12:30 a.m. rollout of the Space Shuttle Discovery
o the pad, the two STS-51 primary payloads are scheduled to be
nstalled into the payload bay on Sunday, June 27.
In upcoming payload milestones, an Interface Verification
est (IVT) is scheduled for Tuesday, June 29, to verify
onnections between ACTS-TOS and Discovery's flight deck as well
