About Human Space Flight
What We Know About Human Space Flight Today
Travel in space exposes the human body to a very different environment from that on Earth. Soon, many more people than ever before will be making brief recreational and scientific flights into suborbital space just above Earth's atmosphere, while nations around the world also plan for longer manned trips deeper into space to explore and utilize the Earth's moon, asteroids, or even other planets and their moons. These opportunities mean that we need to learn more about how the human body responds to the space flight environment so that we can anticipate health problems, both during flight and upon return to Earth. We also need to understand how to design vehicles, habitats and spacesuits and how to create and train teams of people to encourage the success of these human missions into space.
We've known that the body of the astronaut changes in multiple, complex ways during space flight since the early days of space travel, and much more will be learned over the next 10 years as we continue to observe astronauts living and working on the International Space Station, which is currently orbiting Earth. Soon after arriving in space, the human sensory-motor system (which provides our balance and sense of spatial orientation) and cardiovascular system (the heart and blood vessels) alter to accommodate the new sensations and the head ward fluid shift that occurs in the weightless environment; thus the astronaut can feel dizzy and motion sick and have head congestion. As the flight gets longer, bones and muscles can get weaker, because they are no longer being exercised by supporting the bodys weight. The immune system (which helps your body fight off infection) also weakens, making astronauts more likely to get sick if they are exposed to a virus or bacteria. Exposure to high levels of radiation in space could lead to a higher risk of getting cancer, especially after a long flight, or radiation sickness during even a short flight. In addition, altered light and dark cycles as you orbit the Earth or another planet, and altered sleep patterns due to the strange new environment, can cause sleep deprivation, which, coupled with the stress associated with being far from Earth, busy schedules, confined conditions, and the small number of people one interacts with day after day, can lead to errors and changes in behavior. Some of the physical and behavioral changes occurring during space flight may also cause further difficulties upon return to Earth.
We already have many countermeasures (solutions to the problems) to help minimize the hazards of spaceflight to the human being, such as some remote medical care; a nutrition and exercise program; thoughtfully-designed vehicles, spacesuits, mission plans and tasks; training before spaceflight; Earth-space communications systems; and in flight entertainment. Unfortunately, we still do not clearly understand how and when space affects the human body or the long-term effects of space flight on human health after mission completion. Without that understanding, it is difficult to find the most effective countermeasures to the hazards of human spaceflight and the methods for medical care in the event of an accident or other in flight medical emergency. Thus, future human exploration of space to new destinations and for new purposes will require that we learn about the space environment, the effect space has on the human body, and new vehicles and equipment to allow us to go there.
Past human space exploration has influenced the thinking of scientists, politicians, artists and the general public and has lead to new discoveries and products. Now it is time to ask you — What is the future of human space exploration and why is it important?

Please note that the information summarized above and the website links below provide a good starting point for youth to get background information about human space flight. We encourage any youth to read and explore this information and to identify additional books, articles or electronic information on their own to seek inspiration for their entry to the youth art competition.
