The Future of Space Travel
In the future, will space travel become as common as the annual family vacation to Disney World?
We've already had several space tourists. The first space tourist in history was Dennis Tito, a multimillionaire who had a dream of going to space and was financially able to make that dream come true. Tito doesn't like being called a space tourist. He prefers to be called an "independent researcher" since he did perform several experiments while on his trip, er, mission.
Dennis Tito made an arrangement with the space tourism company Space Adventures, Ltd., and joined Soyuz TM-32 on April 28, 2001. It was reported that Tito paid $20 million to go on the "mission," but some of his friends say that it was a mere $12 million.
Mark Shuttleworth was the second space tourist to pay for a trip to space. Shuttleworth, another multimillionaire (surprise, surprise) is reported to have paid $20 million for his 2002 space adventure as well. Shuttleworth's space flight was also arranged by Space Adventures, Ltd. He went to space aboard the Russian Soyuz TM-34 mission.
The third space tourist was Gregory Olsen in 2005. Olsen trained as a scientist, and his company produces specialty high-sensitivity cameras. Olsen used his time on the ISS to conduct a number of experiments mostly to test his company's products.
In September 2006, Anousheh Ansari, an Iranian American, went to space aboard Soyuz TMA-9 and became the fourth space tourist. Ms. Ansari prefers to be called a spaceflight participant.
Then on April 7, 2007, Charles Simonyi, an American billionaire of Hungarian descent, became the fifth space tourist when he flew about the Soyuz TMA-10.
Is there a future for the space flight industry? My guess is yes! There have already been five. Prices will decrease as space flight becomes more common, and someday a space vacation will be a viable option.

The Planet Venus
The Planet Jupiter
The planet Jupiter is was named by the Romans after their god Jupiter, who was also sometimes called Jove. Jupiter is the largest planet in our solar system by far. It is more than twice as large as all of the other planets combined.
Jupiter might well have become a star when it was born, had it been larger. There is very little (if any) solid matter on Jupiter. If there is any at all, it is hidden deeply inside the planet. Jupiter is made up entirely (as far as we know now) of gases and liquids.
The very composition of Jupiter means that its parts do not rotate at the same speed, but rotation is fast. Jupiter makes one complete revolution in a little less than 10 hours. This very fast rotation plus the makeup of gases and liquids are what causes the bulge at the equator of Jupiter.
Jupiter has an internal heat source. We are sure of this because it actually emits more radiation than it gets from the sun.
There are four large moons and dozens of small moons that rotate around Jupiter, making it a kind of small solar system unto itself.
One of the more outstanding features about Jupiter is the never-ending hurricane called "The Giant Red Spot" in the southern hemisphere. This disturbance has been going on for the last 400 years that we know of. It never abates…probably because it never passes over land (there isn't any) like hurricanes on earth do.
An explanation for the color of the clouds on Jupiter still eludes astronomers. With the conditions that exist, clouds should be colorless, but they are anything but colorless, and they change color over time. We still have a lot to learn! |

Sir Christopher Wren
Sir Christopher Wren once said, "In things to be seen at once, much variety makes confusion, another vice of beauty. In things that are not seen at once, and have no respect one to another, great variety is commendable, provided this variety transgress not the rules of optics and
geometry." For those of you who do not know, Christopher Wren was an English architect and mathematician who became Savilian Professor of Astronomy at Oxford in 1661. He is most famous for the buildings that he designed after the Great Fire of London.
Wren was interested in many things, and over his lifetime, he made many contributions to scientific knowledge and in many different ways. For example, he constructed a transparent beehive for the purpose of scientific observation; he studied the moon and experimented on terrestrial magnetism; and he also performed the first successful injection of a substance into a dog's bloodstream.
Along with Sir Paul Neile, Wren constructed a 35-foot telescope. During this timeframe, Wren also studied and improved the microscope and the telescope.
Wren was fascinated by the planet, Saturn. He began his observations of Saturn about 1652 with the intention of explaining the rings. Wren developed a hypothesis which he wrote in De Corpore Saturni. Before his work could be published however, Christian Huygens (a Dutch astronomer) presented his theory of the rings of Saturn. Wren immediately recognized the fact that Huygens' was a better hypothesis than his own, so De Corpore Saturni was never published.
Wren constructed a beautifully detailed model of the moon and gave it to the king. Although Sir Christopher Wren eventually turned his attention to architecture, he remained fascinated by astronomy all of his life.
