NASA Launches New Hurricane Web Page
Today, NASA launched an Internet resource page highlighting the agency’s diverse hurricane research. The site opens just in time for the 2005 Atlantic Ocean hurricane season, which officially runs from June 1 through November 30. The information is available on the Web, at:

Invisibility Unleashed
Invisibility refers to the state of an object which cannot be seen. An object in this state is said to be invisible (literally, “not visible”). The term is usually used as a fantasy/science fiction term, where objects are literally made unseeable by magical or technological means. However, its effects can also be seen in the real world, particularly in physics. [Read more…] about Want to be Invisible!
Are we alone ?
In the beginning, when all was fire, there were no stars or planets, no atoms or molecules… and no life. Eons passed, and life appeared on at least one small planet orbiting an average star in a spiral galaxy called the Milky Way. On that planet, one species, endowed with the capacity to think and speak, began to wonder: Did it happen only here. [Read more…] about Life Beyond Earth
NASA Still Searching glitch
NASA plans to launch space shuttle Discovery , though engineers have not nailed down the cause of the problem that forced the space agency to abandon last week’s attempt.
NASA first had trouble with the gauges during a test of the fuel system in April. Although engineers never figured out the cause of the problem, they replaced electric cables and transistor boxes and swapped out the fuel tank itself. The gauge performed well during a test in May, leading shuttle managers to think they had solved the problem.

Grumann A-6E Intruder
Designed in the late 1950s, the A-6 is an all-weather long-range carrierborne attack aircraft able to operate by day or night. The first of six YA-2F1 prototypes flew on April 19, 1960 with the first of 482 production A-6As being delivered to the US Navy beginning in 1963. The Intruder played a large role in the Vietnam war, flying over 35,000 combat sorties by 1973.
The definitive version is the A-6E which includes an APQ-148 multi-mode Doppler radar with terrain mapping and track-while-scan capabilities. Included beneath the nose radome is a laser spot tracker and laser ranger and designator. All A-6Es in service are due to be retired by the year 2000.
“Stripped of all its outer encrustations, spirituality emerges as a science, as scientific as any other, as verifiable in its results. Let any seeker take it up and let him create in the laboratory of the soul the conditions that are prerequisite; as sure as the day follows the night shall he rise into the Kingdom of God”
“God is the soul and the soul as in God, as the sea is in the fish and the fish is is the sea.” —St. Catherine
The term ‘Spirituality‘ is hard to define. The scope and extent of the subject is so vast and varied in its many aspects that it can hardly be put into so many words. Suffice it to say that it deals with the immutable and eternal facts of life—the active principles that are enlivening the entire creation. The quest for the ‘Spirit’ and for the ‘Laws of Spirituality has ever been in the human breast from the dawn of consciousness in man; yet with all its hoary antiquity, the subject retains its freshness as ever before and shall continue to do so. The Spirit or Soul is the vital flame in man, in the light and life of which he lives and has his being, and no wonder that in every clime and in every age, the leaders of spiritual thought—the sages and seers, the saints and sadhs—have attempted to solve the mystery of life. The subject of Spirituality is concerned purely with the problems connected with the Spirit or Soul—to wit its origin or source, what it is, its seat in the body and its relation thereto, how it functions in the physical world, whether it is possible to separate it at will from the body and bodily adjuncts, the mind and the senses, and if so, the various processes connected therewith. It deals with the spiritual journey through different spiritual planes and the spirit’s capability of traversing the same, the ultimate goal or destination to which this journey leads, and other allied topics, such as the welfare of the spirit, how to feed it and with what, for on its health depends the health of the mind and the body. These are some of the vital questions that fall within the purview of our inquiry.
Sikorsky H-53 Series helicopters combine power and versatility like nothing else in the sky. They’re at home in searing desert heat. Arctic cold. And everything in between. Flying a gamut of missions. Including heavy-lift operations. Military transport. Search and rescue. Vertical replenishment. Vertical onboard delivery. Airborne mine countermeasures. Advanced early warning. Minesweeping. Humanitarian aid. Disaster relief.
The CH-53E Super Stallion and MH-53E Sea Dragon can carry 16 tons of supplies, cargo, vehicles, artillery, and troops for 50 nautical miles. They operate at cruise speeds of 170 knots. And, with air-to-air refueling, H-53E Series helicopters have unlimited range.
And they’ll only get stronger. Sikorsky is currently developing an installation kit to put the 4,750 shp T64-GE-419 turboshaft in the MH-53E. And cockpit upgrades are under way for both the Marine CH-53E heavy lifter and Navy MH-53E minesweeper.
The MH-53E is used primarily for Airborne Mine Countermeasures (AMCM), with a secondary mission of shipboard delivery.
The MH-53E was derived from the CH-53E Super Stallion and is heavier and has a greater fuel capacity than its ancestor. The MH-53s can operate from carriers and other warships. Sea Dragon is capable of carrying up to 55 troops or a 16-ton payload 50 nautical miles or a 10-ton payload 500 nautical miles. The MH-53E is capable of towing a variety of mine-sweeping countermeasures systems, including the Mk 105 minesweeping sleed, the ASQ-14 side-scan sonar, and the Mk 103 mechanical minesweeping system
They are the living framework of your body – one moment able to withstand great tension, the next a wonder of compression. What a different world – a better world – it would be if mankind could harness this type of technology in his own handiwork. Compared to the human bone structure, however, the frameworks that man has produced are decidedly primitive. So, lets take a closer look at your bones.
The bones provide the structural frame-work of the body. They keep the organs in –place and maintain the shape of the body.Bones are very light. The 200 odd bones in your body weigh less than 20 pounds. They are however, extremely strong. As mentioned they have the qualities of both compression – allowing us to hop, skip and jump – and tension, allowing us to carry heavy objects. How is this accomplished? Criss-crossed through the concrete-like calcium in bones run fibers of collagen, which provide support and reinforcement. So, effective is this design structure that bone is eight times stronger than reinforced concrete.
What else is unique about the bone structure? For one, thing from birth they are constantly growing for about twenty years. Yet, there is no halt to their function. The bones are also self healing. If a shaft in an engine breaks, we take it out and find a new one. But if a bone breaks, we expect it to mend itself and, after a while, to be as good as new.
The joints between our bones are self-lubricating. This aids in transmitting the force and power from one bone to the next. In fact, the joints between bones normally show no wear at all, yet they are able to withstand a weight that is three to ten times the body weight. Because of the lubrication, very little energy is lost to friction. The end of long bones is also made of bones that are spongy and more resilient. This aids in resisting impact injuries. Inside the bones, a marvel of creation is taking place. Here new blood cells are made, and these are constantly renourishing our indispensable blood supply.
Your bones are truly masterpieces of design. Just, imagine, if your bones were replaced with the next strongest material known to man, steel, they would weigh about 800 pounds – without the compression benefits of the real thing. So, we can be grateful that we are kept together by something that man can only marvel at – human bone.
