Expedition to Mars: no going back


A few days ago on the website space.com and in a number of other western websites published the news that a certain company, which is developing the project to send a manned mission to Mars without a return , received the first capital injections from their sponsors.

What is the essence of the proposed company “Mars One” mission to Mars?
The fact that it will fly in the same direction. The mission is planned irrevocable. In the first flight after a series of robotic missions to send an expedition of 4 volunteers and stay there forever. They’re there to, as the article says, to prepare the way for the colonization of Mars in these expeditions.

Even today , in principle, mankind can send a manned spacecraft to the Red Planet . It is obvious that a ship of this class should not start from the surface of the Earth, and with an intermediate Earth orbit. That is, the ship must be assembled in orbit. The experience of such work in humans is available. An example is the Soviet orbital station , and then the ISS. If it is possible to construct the station in orbit , it is possible and the spaceship there to collect. The output of the ship to an interplanetary ballistic trajectory also does not cause any problems . It is we, too, can do. Next arrival at Mars and output spacecraft into orbit around it – it is also the power of modern technology . But then the problems begin. You can equip the ship lander . And to put this module safely on the surface of Mars can also be . But back … Back still does . Mars , though smaller than Earth , but to start from the surface will need a lot of fuel. With the return of the crew will be in big trouble. Start with the planet – that’s different than starting from Earth or Mars orbit .
That’s why NASA its first interplanetary mission plans to send to Mars is not as much further – to the asteroid belt . Have to fly farther , but with the return of the expedition such problems do not arise.
The company is “Mars One” is planning a mission with no refund.
Here at the moment such is the state of terrestrial technologies. Returned an expedition to Mars , we can not yet realize .

I do not in any way deny the need for exploration of other planets in the solar system. This is, of course, need to do. But sending manned expeditions to the surface of the planets can only be developed when the interplanetary engines are more efficient, allows one to overcome these distances are not ballistic, and for arbitrary trajectories, and technology return the ship back to Earth.


A celebrity in Peru’s capital has become a dog skateboarder


Bulldog named Biuf began to develop a skateboard when he was not yet a year old, and fell in love with him so that now constantly rolls around in a park in Lima. Dog himself acceleration, turns and stops when needed.

Thanks to the home page Biuf gathered almost 15,000 fans. And his host, inspired by the success of his pet, decided to open skeytshkolu for dogs and give the money to help abandoned pets.

you just look at it =)


In a spectacular show turned the demolition of the old bridge Milton-Madison in the U.S.


In a spectacular show turned the demolition of the old bridge Milton-Madison in the U.S.
The engineers had to do not just blow up the structure, which is almost 90 years old, but also accurately calculate how it will be falling apart and where to fall. The fact that parallel the old bridge already built a new one. And it was necessary to hold such a rough operation as demolition, very delicately. All went well. Span gracefully donkey input. His cut and hand over to scrap.


And here is my story


Finally I decided to open a blog. I’ll start from the end. Tired of dull and negative news. Well I’ll start. One morning I woke up, took out his tablet and decided to read what is going on in the world this morning. Stopped in for a terrific news sites and what I saw there. Syria wants to bomb, in Germany the train went off the rails in Libya overthrows the next government, the U.S. started selling another phone. If you try to find at least one interesting piece of news I was waiting for a deep disappointment, climbed three of the most popular news resource I found not a single positive news. In the end, I got a charge, but only the negative energy, and so wanted to read, about what is really interesting and good. The next morning, the situation repeated itself. And so, week after week. Tired. Bud is good news does not exist. I started looking for … And you know found a lot of interesting, fresh, and most importantly a good charging energy news. On the pages of his blog, I would like to share with you such news and discuss them.
