To play the movie clips, you may need to first install the
Quicktime Movie Player located in the /SOFTWARE/QUICKTIM
directory on the CD. Loading the AntMo2SP.mov movie in the
Quicktime Movie Player
will display a window like below.
Click on the arrow in the bottom left-hand corner to play each movie. A
discussion of the movie clips follows.
Antenna Movie
The first movie clip,
AntMo2SP.mov (3,513K Movie),
shows a time lapse video of
the SIR-C antenna under construction in a clean room. The video uses time-lapse
photography to show the building of the SIR-C radar. Construction is at the
Jet Propulsion Laboratory in Pasadena, California. The construction takes place
in a "CLEAN ROOM," which is continually having its air filtered and circulated.
The engineers constructing the radar change their clothes when they begin to
work with the electronic equipment. This equipment is extremely sensitive and
even the smallest dust particles could potentially disrupt their functioning.
The video shows the construction of the SIR-C antenna and electronics over a
period of several months during 1993. The antenna is the huge, billboard-sized
structure. The massive support structure of girders on the back of the antenna
is designed to keep the antenna very flat when in space and also holds the
electronic components to operate the antenna.
Shuttle Launch and Land
The second movie clip,
LaunLand.mov (4,836K Movie),
shows the Space
Shuttle Endeavour being launched on one of the SIR-C missions, the SIR-C
antenna in the Shuttle payload bay and then the Endeavour landing at Edwards
Air Force Base in California
SIR-C Supersites
The third movie clip,
SiteShow.mov (9,965K Movie),
shows the location of
all of the SIR-C supersites on a map of the world.
Ground Data Collection
The fourth movie clip,
ManausCR.mov (2,270K Movie),
shows a video taken at
one of the supersites during the first SIR-C mission in April 1994. The video
was taken at the Manaus supersite in the Amazon, Brazil. It shows a large
triangular-shaped reflector which was used to help calibrate the SIR-C radar
data. A triangular-shaped reflector is used because we know its radar cross
section, so we can compare with the measurement from the data. The reflector
was placed in a clear-cut area (for raising beef cattle) with uncleared rain
forest in the background
Radar Sees Through Clouds
The fifth movie clip,
PrAlbert.mov (1,126K Movie),
compares the
astronauts view from the Space Shuttle with a radar view of the Prince Albert
supersite in Canada.
Mapping Snow Wetness
The sixth movie clip,
MammoWet.mov (2,922K Movie),
shows a map of snow
wetness produced from SIR-C data obtained over Mammoth Mountain in California.
Maps like this can be used to predict run-off in the Spring thaw. This is
important in Southern California (and many other places world-wide) since much
of their water comes from run-off in the Sierra Nevada.
A New View of Death Valley
The seventh movie clip,
DVMoviSP.mov (1,088K Movie),
shows a flight around Death
Valley in California generated from radar data overlaid on a map of surface
heights.
Getting Close to a Chain of Volcanoes
The eighth movie clip,
GalapMSP.mov (5,981K Movie),
shows a flight around the
Galapagos volcanic island chain in the Pacific generated from radar data
overlaid on a map of surface heights. The surface heights were also obtained
from radar data, using the technique of radar interferometry.
Radar and the Gorillas
The ninth movie clip,
Gorilla.mov (4,694K Movie),
shows SIR-C data being
used to help scientists map the remaining habitat of the mountain gorillas in
Rwanda, Africa. These gorillas live in an area which is very difficult and
dangerous to access, and which is almost always covered in cloud. Hence the
name given to these gorillas in the Hollywood motion picture based on scientist
Diane Fossey's life story: 'The Gorillas in the Mist' .
