They know that they can die even before reaching the planet, and even if they get there, it’s most likely that they will die too. And these assumptions are very difficult refute, especially when you consider that everything that ever went to the Red Planet never returned back to Earth. Continue reading
As the prospect of a permanent colony on Mars is getting closer with every new press release from the Mars One project, it probably makes sense to remember that any person who will move permanently to Mars will most likely die untimely and painful death.
Here are some things that are most likely to cause it (all kinds of technical problems are excluded from consideration):
First of all, the Mars colonists will be subjected toradiation before having set foot on the threshold of their new home. Technically, the radiation level Continue reading
Science in 2013 played a more important role than ever. At the same time, many intriguing discoveries were made. Here is a list of five major scientific discoveries according to the magazine National Geographic.
1. Space has become more ‘crowded’
In 2013 researchers from California Institute of Technology suggested that there are no less than 100 billion exoplanets in the orbits the Milky Way’s stars.
Obviously, not all of them are suitable for living. The November report from NASA Keck Observatory suggests that one out of five stars may have Earth-like planets in their habitable zone. More recent climate studies of habitable zones claim that this probability may be too high although there are still a very large number of potentially habitable planets. Continue reading
Space is getting closer
In 2014, two spacecraft that will help people finally reach Mars will be tested. In September, NASA will launch spacecraft Orion, designed for deep space missions, in a 4-hour flight around the Earth.
Also next year the first launch of the rocket Falcon Heavy, developed by a private company SpaceX, will take place. It is able to Continue reading
During the World’s Fair in New York in 1964, science fiction writer Isaac Asimov made predictions about how the world would be 50 years later, which were published in the newspaper The New York Times. Reading them today, you can see that the author managed to predict nearly all modern technological achievements!
According to Asimov, half of the electricity in 2014 will be produced by nuclear power plants, and solar power stations will operate in the vast deserts of Arizona and Kazakhstan. The connection will be satellite-based and spacecraft will successfully reach Mars. Continue reading
In the “War of the Worlds” by Herbert Wells Martian invaders were defeated by the common cold, which none of the sides took into account. Could something similar happen to the astronauts who will land on Mars? What if the first extraterrestrial life form humans will come into contact with will be viruses? These issues are posed in the journal Astrobiology by Dale Griffin.
Biologists do not consider viruses living beings. They are smaller than bacteria and cannot reproduce themselves: that is why to survive they need to invade a cell and use its genetic tools. Nevertheless, it is viruses that Continue reading
Space continues to beckon U.S. billionaire Dennis Tito. He was there in 2001 as the world’s first space tourist, having spent a fortune to buy a ticket to the International Space Station. Now he is planning a further expedition – to Mars. However, this time the billionaire will not fly to space himself: two volunteers – a man and a woman – are invited for this mission. For this purpose, Tito established a fund Inspiration Mars and called the project Mission for America. Continue reading
Hoffman is one of about five hundred people who lived through the unique experience of seeing Earth from its orbit. Imagine that being in space, you can pull your hand and completely close our planet – so that all our knowledge, the whole humanity, and every person who has ever lived on Earth, simply disappear. This very clearly shows how vulnerable we are. That is why, according to Hoffman, for long-term survival of our species we need to become a multi-planetary race.
It should be understood that space is not Continue reading
Outer space has always attracted and perplexed humans. Its mysteries fascinated, perturbed our imagination, and forced us to go deeper into the unknown. However, the more people studied space, the more mysteries they have come across. At the moment, scientists came up with seven major mysteries in space, the number of which can grow over the next decade or so.
Mystery #1: Is there life on planet Mars?
The so-called “Red planet” has long been a stumbling block for scientists. Not quite a black hole or the Andromeda nebula, located literally next door, it is causing so many questions… Continue reading
As far back as combined human history can go, people have always wondered whether they are alone in the universe.
In September of 2013, a group of British scientists has made a statement saying that during the air-travel in a balloon in the uppermost layer of the atmosphere, a fragment of the cell was discovered, which may be an indication of the presence of life forms in space.Some individuals and proponents of conspiracy theories often put forward the new “proof” of alien visits to Earth, and even scholars argue that they routinely discover signs of presence of extraterrestrial life. Here are five statements from scientists about the existence of extraterrestrials.
Microbial life forms in meteorites
NASA’s scientist Richard Hoover published on March 4, 2011 a scientific article in which he presented evidence of finding fossils of the blue-green algae in carbon-containing meteorites from outer space. Hoover looked at pieces of meteorites using scanning electron microscopy methods and found fibers and structures resembling, as stated by the scientist, these tiny single-celled algae.
Some members of the scientific community reacted skeptically to the Hoover’s discovery, partly because his research findings were Continue reading
