The largest planet

People were engaged in agriculture in the stone age, 30 – 35 thousand years ago. This is evidenced by the notches on animal bones and rocks, cave paintings. This is, perhaps, the earliest “scientific notes”, in which the authors noted the different phases of the moon and count days and nights.

Monitored by our astronomical instruments, the universe consists by weight of about 76 percent hydrogen and 23 helium. Only slightly more than one percent accounts for all other elements of the periodic table.

It is estimated that the galaxy contains more than a hundred and twenty billion stars and to represent its enormous size, we will give one comparison: if the path from the Sun to Earth light travels in 8 minutes, the diameter of the galaxy it will for a hundred thousand years.

To show the progress made over half a century in the study of the Universe, astronomer Paul Couderc came to a startling comparison. Suppose that all known astronomy to 1900 area of the Universe displayed on the plan area of one square meter. Continue reading

Martian Chronicles

“It is good to wonder, said the philosopher. Space travel has again made children of us all”.

To be very brief and concise, that I sometimes even work, then advise, as it is a brilliant creation that deserves repeated reading.

To be a little chatty, and allow yourself to speculate about the book, we can’t help but notice, what I like about it, absolutely everything – from the atmosphere of the text, the storyline in General and how it builds up the narrative of the book. Yes. This is not a novel, or solid piece. The story is built through short stories related to each other not how much the main characters, and how the very idea that revolves around the red planet, Mars.

But she’s great as written. As these stories fascinate the imagination. How bright the picture turns out before my eyes. if you’re in the rocket, which is sent to a dark and unknown planet Mars.

I don’t want to be objective, but from me not require, right? After all, I write a review. And feedback means transfer THEIR feelings and experiences. So I couldn’t understand people who wrote negative reviews about a boring story. I can’t understand my friends who believe this book is one of the weakest ideas of the author. Continue reading

How long to fly to Mars?

Flight to Mars, flight to Mars how far is Mars how to fly to Mars, mission duration to Mars

The planet Mars is one of the brightest objects in the night sky. Like a bright red star, it is visible to the naked eye in the night sky. Approximately every two years, Mars and Earth reach their closest point, called “opposition”. At this point, the distance between Mars and Earth is about 55 million kilometers. Almost every two years, the scientists take this opportunity to send to the red planet spacecraft. So how long does it take the spacecraft to reach Mars?

The total time of flight from Earth to Mars varies from 150 to 300 days, depending on the speed of launch, the position of the planets, the route and the amount of fuel on Board.

The first spacecraft to reach Mars was Mariner 4. The device was launched on 28 November 1964. On Mars he arrived on 14 July 1965, where he successfully made a series of 21 Photos. Continue reading
