An international group of scientists calculated the minimum size of an interstellar spacecraft.
This is reported by the media.
It is now known that scientists have engineered a ship with the intentions of its permanent stay in space for thousands of years. In addition the crew will consist of several generations of colonists.
It is noted that if the flight in close to Land spacecraft will take astronauts a few years, then travel to other galaxies requires extremely time-consuming.
The researchers expected the size of the ship, on the basis that it will be over 6.3 thousand years to move with a speed of 200 km/h. According to their concept, this ship will need a crew of at least 98 people.
But researchers note that a major problem is the food, which must be secured dozens of people on a starship.
Given that dry food supplies would not be a viable option, as they will deteriorate over centuries of travel, the ship and crew had to be equipped for growing your own food, which in turn raises the question of the size of the ship of the future.
“The heavier the satellite, the more expensive it is to run into space. Then, the more / heavier the ship, the harder and more demanding will be the driving system. The amount of food that we can produce, is directly related to the surface area inside the ship, which in turn is connected with the population on Board,” write the researchers.
However, it is worth noting that thanks to the space telescope “Hubble” astronomers have new images of the ice giants Uranus and Neptune.
It became known that Uranus was brighter polar cap of clouds, and Neptune visible dark storm.
In addition, it is noted that at the North pole of Uranus is good enough an enormous area of white color, which is likely to be long-term and storm apparently formed due to seasonal changes in atmospheric flow.
In the picture of Neptune shows a dark anticyclone, appeared in the southern hemisphere of the planet. This is the fourth anticyclone, which oversees Hubble.
We will remind, the science of space can change.
As reported “Znayu”, possible extraterrestrial life, NASA even said where.
Also “Znayu” wrote that scientists have shared a unique video of the Earth in 250 million years.
