The International Space Station (ISS) is the largest and most complex international scientific project in history and represents a move of unprecedented scale off planet Earth. The station draws upon the scientific and technological resources of 16 nations: United States, Canada, Japan, Russia, 11 nations of the European Space Agency and Brazil.More than four times as large as the Russian Mir space station and a mass of about 1,040,000 pounds, the ISS measures 356 feet across and 290 feet long, with almost an acre of solar panels providing electrical power to six state-of-the-art laboratories. The station orbits at an altitude of 250 statute miles with an inclination of 51.6 degrees. This orbit provides accessibility by all the international partners.

Assembled in orbit, the ISS is an example of the first hands-on work in space, involving more spacewalks than ever before and a new generation of space robotics. About 850 clock hours of spacewalks were required by Russian and U.S. astronauts over five years to maintain and assemble the station (which is scheduled to be complete by 2010 according to the Vision for Space Exploration). The United States developed and currently operates the station. International partners contributed key elements to the ISS including Canada’s 55-foot long robotic arm for maintenance and assembly, Japan’s laboratory with attached exposed exterior platform, Russia’s research modules and spacecraft, and the European Space Agency’s pressurized laboratory.

The station represents an unprecedented state-of-the-art laboratory complex in orbit, more than four times the size and with almost 60 times the electrical power for experiments — critical for research capability — of Russia’s Mir. Research in the station’s six laboratories have already lead to discoveries in medicine, materials and fundamental science that will benefit people all over the world. Through its research and technology, the station also serves as an indispensable step in preparation for future human space exploration. Research currently being performed aboard the station includes: investigations in protein crystals; tissue culture; life in low gravity; flames, fluids and metal in space; the nature of space; observations of Earth; and potential for commercialization.The first crew to live aboard the International Space Station, commanded by U.S. astronaut Bill Shepherd and including Russian cosmonauts Yuri Gidzenko as Soyuz Commander and Sergei Krikalev as Flight Engineer, was launched in early 2000 on a Russian Soyuz spacecraft.

• Complete the International Space Station by 2010
• Retire the Space Shuttle by 2010
• Develop the Orion spacecraft (formerly known as the Crew Exploration Vehicle) by 2008, and conduct its first human spaceflight mission by 2014
• Develop Shuttle-Derived Launch Vehicles
• Explore the Moon with robotic spacecraft missions by 2008 and crewed missions by 2020
• Explore Mars and other destinations with robotic and crewed missions

In a study by Zogby International of what Americans think of the NASA space program, 44% of respondents thought that tax dollars spent on the program should remain the same, 32% thought it should be increased, 16% thought it should be decreased and 4% wanted it scrapped altogether.

I’ve heard many a person argue against the apparent profligate spending of the U.S. government on the NASA space program at the expense of housing, health, and education (funny, I don’t hear them complaining about the excessive amount spent on the military). Benefits of the program to humanity are doubtful at best, they complain. Who cares about space, the existence of planets in the Vega system or dark matter when we have so many problems to fix right here on Earth? This practical though myopic view has always been the bane of research, by posing the challenge to defend its value NOW. Research doesn’t work that way (hardly anything of value works that way); discoveries often occur serendipitously (e.g., Fleming’s discovery of penicillin); and often following many years of arduous and dedicated work. NASA’s research is no different. Its entire space program is based on unknowns and “what ifs”, on faith and on hope and ultimately on a vision of the future, a dream.

I have and always will support the NASA program… their dream. I too am a dreamer. Aren’t we all? Isn’t that our very nature? To dream?

NASA, better than any other organization, whether private or government-funded, represents humanity’s eternal dream to understand our universe and ultimately ourselves. We have always been and will continue to be explorers, whether it was Jacques Cartier who sailed across inclement seas up the Gulf of Saint Lawrence to discover a primitive Canada, Jacques Cousteau who dove the abysmal depths of a vast sea to coax out its dark secrets, or Captain Jacques Quasar who sailed the solar winds of the Milky Way Galaxy to find sentient alien life and ultimately answer the question of who and what we are. What program better represents our yearning for knowledge, understanding, and ultimately wisdom? The space program has always been about humanity’s search for meaning in an existentialist chaos of apparent vacuum. What is the nature of our existence? Why are we here? Our outward journey has always been ultimately about coming home.
