If an ice worm can figure out how to survive in extreme temperatures with little oxygen, then there is hope for humans to be able to live in outer space. There are always technological developments that will allow people to reach new limits. At some point, this will include living in outer space.
Space travel has long held a fascination for both NASA and the layman. Successful space flights have produced a sense of wonder and, with every trip, broaden our understanding of how our universe works. The US is currently setting its sights on flights to Mars, which currently seems like an impossible dream. The ice worm, a real species that lives in glaciers and other icy regions, can provide an indication of the potential for human survival on the Red Planet and other seemingly impossible locales in our solar system. The ice worm survives by eating things like algae and pollen, food sources that do not seem like even they could survive in such low temperatures. Scientists understand the atmosphere on Mars can also be brutally cold. It has already been proven that humans can survive for extended periods in the International Space Station and on the moon, but in looking to reach and perhaps settle on the Red Planet, space explorers should study how the ice worm survives in extremes that exist here on earth, and apply their findings to human space flight.
No, the physical limitations of the human body makes it impossible to survive in space without serious help from technology. The cold of space is far worse than the inside of a glacier, and the lack of oxygen makes it a non-starter. Anaerobic organisms like bacteria can survive in vacuum, but the step for pretty much all other forms of life on earth is just too great to bridge.
It is admirable that researchers study how ice worms survive harsh environments in order to use the findings to help humans. However, we need to understand that humans are not, and will never be, worms. We are not the same species, and glaciers on Earth are not the same as ice in space.
