(meteorobs) TONIGHT'S SPACE SHUTTLE LAUNCH TO BE VISIBLE FOR US EAST COAST
From: <A HREF="aol://3548:Skywayinc">Skywayinc</A>
Those living along the U.S. East Coast will have an excellent chance at
seeing the Thursday night Space Shuttle launch as the Endeavour 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 ENDEAVOUR SHOULD BE VISIBLE ALONG MUCH OF THE U.S.
EAST COAST THURSDAY 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 101st 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 Endeavour is expected to leave Pad 39B at Florida's Kennedy
Space Center on Thursday, November 30 at 10:06 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 Friday attempt to launch would come at around 9:41 to 9:43 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 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.
