Sun Rise, Sun Set

Forget about all of this talk of Global Warming….

Maybe we should be more concerned about Global Cooling….

Our Sun has a larger impact on the temperature and climate changes happening to Earth than pollution, the loss of rainforests, aerosols, or any other Global Warming propaganda that is out there right now.

Canadian scientists have been studying the impact of sun spots since the end of World War II.
  

Solar activity can fluctuate and usually has spans of 11 year cycles.
 

Scientists say activity lately has been very quiet.
 

This is disturbing and may mean that a period of bitter cold could be on the horizon.
 

This happened before in the 17th century, and in Europe caused crop failures, famine and death.


Canada is seeking more funding for the use of solar flux monitor telescopes to better observe what is going on with the sun.


They have been using radio-telescopic monitoring since World War II.

You've Got Mail!

Forget e-mail....

How about space mail?



In an experiment combining elements of a package delivery service, the sport of kite surfing and a REALLY big fishing reel, Russian and European engineers sought to pioneer a technology that could be used in the future to retrieve cargo from space.

The experiment involving a 19-mile, super-strength tether hit a glitch, however, when the line failed to unwind fully, but Russian Mission Control said it hopes to salvage the test by recalculating the landing capsule's orbit.

"Even a fishing line could get stuck sometimes," Mission Control said spokesman Valery Lyndin.

The second Young Engineers Satellite, whose preparation involved nearly 500 university students from Europe, Japan, North America and Australia, was launched into orbit September 14 on a Russian-built Foton-M3 spacecraft, along with other European Space Agency experiments.

The goal of the YES2 experiment was to deliver Fotino -- a 12-pound reddish spherical capsule the size of a beach ball -- to Earth with the help of a long tether made of a substance the European Space Agency described as the world's strongest fiber.

In the experiment, the Fotino, held in a metal brace by straps, was to be shot out from the Foton-M3 spacecraft with springs as the tether gradually unwound, swinging the capsule forward into a lower orbit about 18 miles below.

About 2½ hours later, after gravity takes firm hold and the entire unit swings in a vertical position below the spacecraft, the Fotino is then released from its straps and glides through the atmosphere for about 20 minutes before a parachute deploys and the sphere bumps to a landing in the steppes of the Central Asian nation of Kazakhstan.

The capsule has a thermal shield to protect it from the searing heat of re-entry through the Earth's atmosphere, while the tether and the holding clamps burn up.

The experiment went awry when only five miles of the tether were unwound from the spacecraft at about 190 miles above the Earth before the capsule was released.

The reason for the problem wasn't immediately clear, Lyndin said. "It could be that the tether got stuck," he added.

The Fotino is equipped with a radio beacon to allow experts to track it as it glides down through the atmosphere, and Mission Control will try to calculate its current orbit to determine when and where it will land, Lyndin said.

The Russian Space Agency sought to play down the problem, saying the experiment provided a "valuable information about the tether's dynamics in space flight."

"The results of the experiment could be considered partly successful," it said.

Roger Walker, the project manager for ESA's Education Office, also played down the glitch, saying on the agency's Web site that it was a "largely successful demonstration" and that the agency was proud of the students' work, even though full deployment was not reached.

The tether is .0196 inches thick and is made of Dyneema, which the ESA said is used by kite surfers.
