Google recently began a new mapping service. You can find some interesting things if you know where to look. Here's a photo of a
Chinese Air Base .
Zoom-in and checkout the military aircraft parked at each end of the runway. This photo of the
Northern End of the Great Wall of China
shows the railroad passing through the wall. Notice that there are no paved roads.
Take a look at the longest runway in Europe (120 meters wide, 5.4 km long) in this aerial view of Zhukovsy Air Base, near Moscow.

The Sun heats the surface of Mars until it's warm to the touch even though the atmosphere 6 feet above the surface is chilly.
That temperature contrast causes convection. Mixing the dust, winds, and convection triggers dust devils.
See the movies of the
Dust Devils of Mars sent back by the NASA rover, Spirit.

Off the shores of Southern California oil rigs are masked by colorful facades that resemble
small amusement parks. So it is no surprise that unsightly landmarks of high technology are similarly disguised--
in this case, cellular phone towers are made to look like trees, buildings or even works of art.
Some, of course, are more convincing than others. See if you can
Spot the Cell Phone Tower.

The world's first artificial satellite was about the size of a basketball,
weighed only 183 pounds, and took about 98 minutes to orbit the Earth on its elliptical path.
Forty-seven years ago Sputnik I started the space age and the U.S.-U.S.S.R space race.

Color TV
is celebrating its 50th anniversary this year.

Richard Grugel, a materials scientist
at the Marshall Space Flight Center, watched video from the
International Space Station in disbelief as Astronaut Mike
Fincke touched the tip of a soldering iron to a wire wrapped with rosin-core solder.
The solder, once heated, became a molten blob with a droplet of
rosin clinging to the outside. It's not surprising that the solder melts.
It's the behavior of the rosin that's amazing. As the
temperature increased, the droplet began to spin, round and round,
faster and faster, like a miniature carnival ride. Get the details at
Soldering In Space.

The U.S. Navy has built an exotic radar system to track
earth orbiting satellites, called
NAVSPASUR.
The giant array built near Lake Kickapoo, Texas, is a two mile long antenna that transmits continuously
on 216.98 MHz with an unmodulated carrier, and has an ERP of 6.3 Billion Watts!
So powerful is the transmitted signal that when the moon passes through the beam, the return echo is
said to be detectable on earth with only a dipole antenna attached to a receiver.

Hot off the NASA satellite. Take a look at the thousands of raw images downloaded from the Mars Rover.
See the sand blasted rocks and the ripples of sand dunes as they fill in craters.
Whoa, did you see that little green guy run behind that white rock?

Do you ever wonder what a 150 foot tall candle would look like? Ever see a cell phone tower on fire? Take a look at this.
W4ZT
says, "Unbelievable! I heard that this was caused by someone using an Oxygen/Acetylene torch to cut
a hole or enlarge a hole in the base of the tower. Insulation on Heliax will burn! Slag will start a fire!"

I think the Do Not Call Registry is working.
The week before it was to go into effect in October we had a flurry of calls. Then silence.
During the first week of November we had several "Market Research" calls. Then silence.
About mid-November the government began prosecution of a West-Coast marketing firm that ignored the DNC list.
Everything has been very quiet since.
