Negative outcomes of the nasa program

Then, there are the risks presented simply by being a long way from Earth. The farther humans get from the Earth, the riskier living in space becomes in almost every way. Everything from fresh food to unexpired medication will be extremely difficult to make accessible with longer journeys farther away. But a mission to the moon or Mars would pose more problems. She said it would also take longer to get back to Earth if there was a medical emergency.

In this approach, initial "phases" include research on the health effects of being in space has also been done in simulated conditions on Earth, from isolation experiments in Antarctica to radiation exposure at Brookhaven National Laboratory in Long Island, New York. Likewise, experiments on the space station will help us to prepare for risk on the moon and Mars — these later phases build on knowledge gained from simulations. Still, no matter how much we may prepare on Earth, every space mission comes with risk, so NASA has set health standards to minimize this risk for astronauts.

These standards describe everything from how much space astronauts should have in a spacecraft to how much muscle and bone loss an astronaut can experience without being seriously harmed. These standards also include levels of physical fitness and health the astronauts need to meet before going into space. She emphasized the complex interplay between these two types of impacts, both of which NASA scientists must keep in mind when planning missions.

Consider the case of Dr. In a flash of insight, Ansari realized that the instrument being developed as part of the colloids experiment might be able to detect cataracts — possibly earlier than ever before. The device is now being used to assess the effectiveness of new, non-surgical therapies for early stages of cataract development.

The device also may have an unexpected return for NASA: It has been investigated as a possible medical tool for astronauts, who may develop cataracts as a side effect of the kind of radiation exposure that they might experience in long-duration spaceflight. Perhaps as interesting is the motivation that space provided to Ansari to pursue a career in science.

He says it traces entirely to a single moment: when he was 9 years old in Pakistan, and he saw the live, grainy television images of people walking for the first time on the moon.

It also shows how the aforementioned strange connections can come about. Just how are the International Space Station and old artwork related? Well, atomic oxygen found hundreds of miles above Earth attacks and very gradually destroys materials used in satellites and spacecraft. NASA Glenn Research Center engineers Bruce Banks and Sharon Miller realized that their atomic oxygen facility could be used in a positive, rather than destructive way: It could gradually remove unwanted material from surfaces without ever needing to touch or rub them.

Their invention has been used to restore two 19th century paintings coated in soot from a church fire in Cleveland, Ohio; the technique also restored a vandalized Andy Warhol painting for the Pittsburgh Museum of Art.

In both cases, no existing art restoration methods would work. Again, the unique demands of space exploration created unique innovation here. How about food safety? Well, NASA invented a system really a seven-step guide to monitor and test food production to try to assure that the astronauts on the way to the moon would not get food poisoning. Twenty-five years later, the Food and Drug Administration and the Agriculture Department adopted that safety system for all of us, and a year later, according to industry, the number of cases of salmonella dropped by a factor of two.

Today, the Statue of Liberty and the Golden Gate Bridge are coated in a protective material that NASA needed to invent to save its launch pads from the destructive effects of hot, humid and salt-laden air.

Vesuvius in A. Examining those carbonized manuscripts under different wavelengths of light suddenly revealed writing that had been invisible to scholars for two centuries. All of these examples only begin to tell the story.

While their existence is a source of pride, we must realize that America did not create the space program with the idea of gaining these collateral benefits. Mariner Mars Pathfinder. Mars Rovers. New Horizons. Pioneer Viking Missions. Manned Space Vehicles. Unmanned Space Vehicles. NASA Calender. Continued Space Program. Positive Effects of the Space Program. Negative Effects of the Space Program.
