(meteorobs) SHUTTLE LAUNCH TO BE VISIBLE ALONG US EAST COAST
Those living along the U.S. East Coast will have an excellent chance at
seeing the Wednesday evening Space Shuttle launch as the Atlantis orbiter
bores through the Earth's atmosphere and into Earth orbit. Full details,
courtesy of Skyway, Inc. are provided below.

Kennedy Space Center)
LAUNCH OF SPACE SHUTTLE ATLANTIS SHOULD BE VISIBLE ALONG MUCH OF THE U.S.
EAST COAST WEDNESDAY NIGHT
LEVITTOWN, N.Y. -- If you have ever yearned to see a Space Shuttle
launch, but have never been able to make it down to Florida, you'll get a
great opportunity -- weather conditions permitting - during the early evening
hours sometime during this week. According to SKYWAY's Joe Rao, the launch
of the 102nd shuttle mission -- and the sixth to rendezvous and dock with the
International Space Station -- should be visible along much of the Eastern
Seaboard of the United States, including the Greater New York Area.
The Shuttle Atlantis is expected to leave Pad 39A at Florida's Kennedy
Space Center on Wednesday, February 7, 2001 at 6:11 p.m. EST. Should the
launch be scrubbed, the launch time will come approximately 23 to 25 minutes
earlier for each successive day that the launch is delayed. . . meaning, for
example, a Thursday attempt to launch would come at around 5:46 to 5:48 p.m.
In order to meet-up with the ISS, the Shuttle will be launched into a
special orbit that is inclined 51.6° to the equator. Usually, after liftoff,
the Shuttle heads out over the Atlantic straight east from Florida, however,
the upoming launch -- specially configured to match the ISS orbit -- will
bring the Shuttle's path nearly parallel to the U.S. East Coast. Discovery
will be visible by virtue of the light emanating from its three main engines.
"It should appear as a very bright, fast-moving star, shining with a
pulsating yellowish-orange glow," notes Rao, adding that observers who train
binoculars on the Shuttle should be able to see it look like a ". . . tiny
V-shaped contrail."
Prospective Shuttle-watchers should make sure that they have an
unobstructed view of the southern and eastern horizons, since, even for many
localities along the US East Coast it will get no higher than 10º above the
horizon just before it disappears from view. "The best views will probably
be from tall buildings or along south and southeast-facing shorelines."
Endeavour will seem to suddenly "flicker-off" exactly 8½ minutes after launch
as the main engines shut-down and the shuttle's orange external fuel tank is
jettisoned over the Atlantic at a point 415 miles southeast of New York City.
At that moment, the Shuttle will have climbed to an altitude of 375,000
feet (71 miles) and should be visible for a radius of some 700 miles from the
point of main engine shutdown.
* In the Southeast US, depending on the distance from Cape Canaveral,
Endeavour will become visible anywhere from 0 to 5 minutes after it leaves
Pad 39-A. The brilliant light emitted by the two solid rocket boosters will
be visible for the first 2.1 minutes of the launch up to a radius of 450
miles from the Kennedy Space Center. Movement: south-southeast to east.
* In the Middle Atlantic region, Endeavour should be visible from 5 to 7
minutes after liftoff. Movement: south-southeast to east.
* For the Greater New York Area up into Southern New England, Endeavour
should be visible from 7 minutes up to main engine cutoff (8.5 minutes after
liftoff). Movement: south to southeast.
Before hoping to see the Shuttle streak across your local sky, you should
make sure that it has left the launch pad! "Watch the launch on CNN, MSNBC
or FOX News Channel, or listen to a local news radio station that is covering
it live," suggests Rao. "Then head outside and start looking skyward."

In the above table . . . the time of closest approach is based on the number
of minutes counted forward from the time the Shuttle lifts off from Florida.
Altitude of the Shuttle is the number of degrees measured from above the
horizon. Azimuth is the horizontal angular distance measured clockwise in
degrees along the horizon from due north. Hence: 0º = North; 90º = East;
180º = South; 270º = West.
As an example, for New York City, the Shuttle's closest approach will come 8½
minutes after liftoff from Florida, with its maximum altitude above the
horizon of 8.0º at an azimuth of 129.6º, or 39.6º south of due east.

Shuttle Processing Note: Preparation for the Launch of Space Shuttle
Atlantis continues on schedule. Over the weekend, the flight crew arrived
at KSC and the launch countdown began Sunday at 10 p.m. EST. One of the
three spacesuits aboard Atlantis was replaced Sunday afternoon and a second
spacesuit was reinstalled today. The additional spacesuit work ensured the
integrity of the fan units on each suit.
On Monday, engineers completed preparations to load Atlantis' power reactant
storage and distribution system. Loading of cryogenic reactants into the
fuel cell storage tanks begins this evening. Early Tuesday, the Shuttle's
mid-body umbilical unit will be demated and final main engine preparations
will begin. Flight crew equipment late stow is slated for Tuesday evening
and the Rotating Service Structure is scheduled to move away from the
Shuttle Tuesday at 10 p.m. Loading of the external tank is schedule to
begin at about 9:16 a.m. Wednesday.
Forecasters indicate a 20 percent chance of weather violating launch commit
criteria on Wednesday. The forecast calls for scattered clouds at 3,000 and
25,000 feet; visibility at 7 miles; winds from the southeast at 8 peaking to
14 knots; temperature at 68 degrees F; dewpoint 56 degrees F; relative
humidity at 65 percent and a slight chance of coastal showers. The 24-hour
delay forecast predicts a 30 percent chance of weather violation.
