Space explorers

Astronomers from other times studied the stars, trying to understand the structure of the universe. However, until the mid-20th century, the study of the universe was limited to observation of a starry sky in the surface of the earth. In the second half of the 20th century, the styles you can into space. This possibility has opened a new stage in the study of the universe.

In its 50 year history of space pilots were launched quite a number of different spacecraft. Among them a huge number of artificial satellites, orbital stations, interplanetary space stations, and more. In the beginning try to understand the difference between different types of spacecraft.

Satellites .

Artificial satellite is an unmanned spacecraft orbiting the Earth in a geocentric orbit. The flights are performed at altitudes from 150 km to a few hundred thousand kilometers. The lower boundary of the altitude of satellites causes the need to avoid rapid deceleration in the atmosphere. Continue reading

Found the nearest planet capable of supporting life

Astronomers from Australia have discovered the nearest potentially habitable planet located outside the Solar system.

Discovered planet is located at the distance of only 14 light years from Earth and about four times more massive than her. It is one of three planets orbiting a red dwarf called Wolf 1061.

“This is a very interesting finding, because all three planets have a relatively small mass to be rocky objects with a solid surface. Planet Wolf 1061c and does amazing as it is located in the “habitable zone” where liquid water and even different forms of life,” says the study’s lead author Duncan Wright from the University of New South Wales.

For their work, the team used the HARPS spectrograph mounted on the 3.6 meter telescope of the European southern Observatory (ESO) in La Silla, Chile.

Need to mention that Wolf 1061 is not the closest star around which planets were discovered. However, it is around 1061 Wolf discovered a rocky planet, and one of them is located in the “habitable zone”. Continue reading

Designing spaceships to travel to distant worlds

This is the sixteenth report on a project on modeling of human presence on Mars called HI-SEAS.

On Tuesday, the crew of mission HI-SEAS for the first time in four months go outside without protective training suits. On our cheeks sparkle with the wind, the fresh air will fill our lungs, and if the weather is good, sunlight will Shine on our faces. We return back to planet Earth.

But before returning there was one interesting thing. Paradoxically, we in the conversations deviated from the earth and even from Mars. We talked about the fact that you will need for the construction, management and life on a spaceship, which will travel to the nearby stars, and which some generation will change the other, because the flights of this kind will last hundreds of years.

These conversations inspired us primarily the commander of our crew Vermeulen Angelo (Angelo Vermeulen). Angelo from Belgium, he is an artist, biologist and researcher space systems. He firmly believes that the legendary the starship enterprise from “Star trek” was basically wrong. Continue reading
