Some Of NASA’s Zero Gravity Experiments
Since the first astronaut was sent into space, there’s been a great interest in zero-gravity conditions for experiments. Most experiments have focused on how a lack of gravity affects living organisms.
Other experiments have looked at chemical reactions and processes without the presence of gravity. While the International Space Station provides the ideal platform for zero-gravity experiments, NASA and other researchers have conducted many using aircraft in free-fall.
The most important experiments have examined the harmful results of humans living in space for extended periods. Initial experiments showed the loss of bone and muscle tissue to be the biggest problems faced by astronauts. This led to further experiments to discover ways to overcome these problems, such as using resistance exercises.
In studying the behavior of substances under zero-gravity, it’s been found that the surface tension of liquids becomes much stronger. This results in clumps with less smooth flow.
A lot of experiments have been conducted to see how zero-gravity can alter the formation of chemical substances. One material discovered as a result is called aerogel. It has a lower density than anything else known to exist.
The continued use of the international space station guarantees more discoveries in the future.
