Magnet can be used to make oxygen in space – research

Categories : Science & Tech

You must have seen astronauts floating in space suits inside the space station in the pictures or videos of the space station built in space. An oxygen giving cylinder is also tied behind them. But what will happen if the supply of space oxygen above them ends? It is said that providing breathable air to astronauts in space is very expensive. Now, when man is going to speed up the mission to the moon and Mars, some technology must be found to make oxygen available there.

In this direction, an international team of scientists has done an important research to prepare a mechanism for making oxygen. He has talked about making oxygen with the help of magnetic mechanism. If this technique works, it will be very easy to produce oxygen in space.

Álvaro Romeo Calvo, a PhD graduate from the University of Colorado Boulder, said that oxygen in the International Space Station is made with the help of electrolyte cells. It breaks water into hydrogen and oxygen. But after that these gases have to be brought out of the system. A NASA researcher has recently said in a study that taking this technology to a planet like Mars is not reliable.

Due to the lack of gravity on other planets, it is very difficult to separate the oxygen. When this process takes place on earth, bubbles of carbon dioxide quickly come out on the top of the soda glass. But where would these bubbles go in a place like space, without gravity? Instead of coming up, they remain trapped in the liquid.

Currently NASA uses a centrifuge process to separate the oxygen, but this process demands a lot of mass, energy and maintenance. Meanwhile, researchers have done an experiment in which magnets can also do the same thing.

The team has designed a mechanism to separate the gas bubbles. The study shows for the first time that gas bubbles can be attracted to a simple neodymium magnet in microgravity and immersed in a variety of water solutions.

Professor Hanspeter Sachuab of Colorado said that after years of research, we have been able to use this mechanism, so that we can separate oxygen from water even in zero gravity. Scientists say that with this research, scientists and engineers can be successful in making oxygen systems and it can also be useful in other research related to space.
