With the launch of the final space shuttle today, Vizme Space has put together a Space Shuttle Tribute. Watch and enjoy!!
This tribute allows you to explore the history of the shuttle program, learn about its many achievements, and appreciate the complexity of this monumental scientific and technical endeavor.
Microsoft has come out with a new online magazine Publicyte which is to be used to promote its public sector initiatives. The new magazine is led by Mark Drapeau, editor and chief.
Drapeau is hoping to make Publicyte, the digital magazine, “a great source of creative thought leadership on technology and innovation for different public sector verticals” such as government, education and health care. “We want to present Microsoft in a new light to influential people in the public and civic sectors and through the media that covers it.”
As well as Drapeau, the magazine will incorporate articles by other writers from Microsoft as well as contributions from writers out with the company. The main focus will be on Microsoft.
There has been no major announcement about the magazine as the company wants the readership to grow naturally. The audience is expected to be public and civic sector professionals. The goal is to influence how people think about issues like social media and government.

Have you ever wondered who makes the tires for the space shuttle? Tires weren’t exactly necessary in the early days of the NASA space program. The first NASA space vehicles such as the Titan II and Saturn V rockets were just that — rockets. After returning from space these rockets would literally fall into the ocean and were retrieved by NASA afterward. When NASA launched the space shuttle program in 1981 it was clear that they were missing the one thing that rockets didn’t need – landing gear. Unlike NASA’s earlier rockets, the Space Shuttles were designed to make a standard airport landing after returning from space. But NASA knew that they would need something stronger than the average tire. So they turned to famous tire maker Michelin Tires to design and manufacture the tires for the Space Shuttle. Before Michelin could secure the contract to equip Space Shuttles with their tires, they had to create tires that could pass NASA’s rigorous tests and stand up to the stresses of space travel and a reentry landing. Since every ounce of weight counts for the Space Shuttle, the tires had to be as light as possible; the rocket boosters which launch the Shuttle into space are only capable of carrying so much weight. NASA has often had to sacrifice vital scientific packages because these weight requirements so the tires couldn’t be significantly heavy. To make the Shuttle tires as light as possible Michelin gave them as very little tread and in the end they only weighed about 205 pounds (for the landing gear tires).
And before any dealerships were putting Nitrogen in tires, Michelin was filling their aircraft tires with it including the Space Shuttle tires. Nitrogen is ideal for the inflating the tires of the Space Shuttle because it remains stable at the high altitudes, pressure, and temperatures that the Shuttle is exposed to. Speaking of extreme temperature, the Space Shuttle tires are exposed to temperatures below 40 degrees Fahrenheit in space to above 130 degrees Fahrenheit when the Shuttle is landing. Furthermore, to handle the excessive speeds of a landing Space Shuttle, the tires are rated for a maximum speed of 259 miles per hour.
Unbeknownst to many, the tires on the space shuttle are actually about the same size as a truck tire. Though the main landing gear tire on the Space Shuttle can hold three times the load of a Boeing 747; in fact, the landing gear tires (44.5×16.0-21 MLG) can hold up to 142,000 pounds. To handle this immense amount of weight the tires are inflated beyond 300 psi. Furthermore, NASA actually only uses the main landing gear tires on the Space Shuttle once before replacing them with a new set. Today, Michelin or specifically Michelin Aircraft Tire Corporation remains the sole tire supplier for the NASA’s Space Shuttles.

A ton of people visited the Bob Bullock Texas State History Museum to view NASA’s successor to the Space Shuttle.
This is an amazing video of Endeavour’s launch as viewed from the rocket boosters:
Wearing her husband’s wedding ring hanging on a chain around her neck U.S. Rep. Gabrielle Giffords watched her husband Mark Kelly command shuttle Endeavour on its final flight.
The space shuttle Endeavour launch has been postponed and will not fly before May 8. Friday’s launch was postponed due to technical difficulties.
Captain Mark Kelly, the commander of the space shuttle Endeavour, said on Tuesday that his injured wife, Representative Gabrielle Giffords of Arizona, was “more than medically ready” to make the trip to Florida for the shuttle launching.
Earth is entering a stream of dusty debris from Comet Thatcher, source of the annual Lyrid meteor shower. Forecasters expect the shower to peak on April 22nd with as many as 20 meteors per hour, although visibility will be reduced by bright moonlight. The best time to look, no matter where you live, is Friday morning during the hours before local dawn. Visit http://spaceweather.com for live meteor counts and more information.
The nursing profession has a long and honorable past. It is one of the healing professions and imbues its practitioners with an aura of respect and, in the minds of many people, goodness. There are actually several different types of nurses. The most common is the registered nurse. There are also nurse practitioners and physicians assistants, and licensed professional nurses who are also known as licensed vocational nurses or LVNs.
Anyone enrolling in one of the many lvn programs in the country can expect to learn the skills necessary to provide care to patients in hospitals, clinics, nursing homes, doctor offices, and rehabilitation hospitals. They may also find employment as home health care workers. In all cases, they will work under the direction of a physician or registered nurse.
The best programs are going to provide students with ample opportunities to gain hands on experience. Students will learn pharmacology, nutrition, physiology , anatomy, and common diseases and treatments. They will be expected to develop leadership skills and to understand the legal and ethical responsibilities associated with nursing. Most programs take around two years to complete, though each school will have its own schedule of classes. Upon graduation students should be ready to apply for state licensing or certification, if is required.
