Bacteria Survives in Space, Without Oxygen, for a Year and a Half

space-bacteria

The bugs were put on the exterior of the space station to see how they would cope in the hostile conditions that exist above the Earth’s atmosphere.

And when scientists inspected the microbes a year and a half later, they found many were still alive.

These survivors are now thriving in a laboratory at the Open University (OU) in Milton Keynes.

The experiment is part of a quest to find microbes that could be useful to future astronauts who venture beyond low-Earth orbit to explore the rest of the Solar System. […]

This type of research also plays into the popular theory that micro-organisms can somehow be transported between the planets in rocks – in meteorites – to seed life where it does not yet exist.

Interestingly, the bacteria selected weren’t known extremophiles, they were selected apparently at random.

Discovery of New Microorganisms in the Stratosphere

Three new species of bacteria, which are not found on Earth and which are highly resistant to ultra-violet radiation, have been discovered in the upper stratosphere by Indian scientists. One of the new species has been named as Janibacter hoylei, after the Distinguished Astrophysicist Fred Hoyle, the second as Bacillus isronensis recognising the contribution of ISRO in the balloon experiments which led to its discovery and the third as Bacillus aryabhata after India’s celebrated ancient astronomer Aryabhata and also the first satellite of ISRO.

The Extremophile Gold Rush

Interesting piece from the BBC:

The UN University says “extremophiles”, creatures adapted to life in the polar wastes, are being relentlessly hunted in what is virtually a new gold rush.
