American satellites zombie: open circuit operation

Defense science agency DARPA has submitted a video that shows how an advanced system Phoenix, quickening spent satellites. As planned by experts DARPA, robots will one day orbital re-use various parts of dead satellites, such as antennas and transmitters.

This makes sense from an economic point of view: satellite launch costs tens of millions of dollars, but in 5-10 years it becomes a waste. To date, of the 1,300 large space objects in Earth orbit only 500 — is operational satellites. In the short space of useful sites and designs that can be reused.

In the video, released DARPA, shows how you can use the exhaust satellites. At the initial stage of the program Phoenix robot approaches the dead satellites, grab his handlers, cut the antenna and attach them small communication modules. Thus scrap of space satellites will be made workable. First experimental space mission of this kind is planned in 4 years. Subsequently, robots Phoenix can perform more complex reconstruction.

The main components of the current phase of the program Phoenix (total — $ 180 million) are the manipulator FREND and capture device based on electrostatics and microfibers. The manipulator must be cut off satellite dishes of different types, with the capture of the satellite should be carried out using a special technology without the use of mechanical parts. Meaning "sticking" to the surface by electrostatic discharge and microfibers like hairs on a gecko lizard legs.

Work on the proof of concept will be carried out to Phoenix in 2015, and the following month DARPA will announce the next stage of research — on a mix of old antennas with new mini-satellites.

Site "Survival in the wild nature", glad to see you. If you come to us, it means you want to get complete information about survival in a variety of extreme conditions, in emergency situations. Man, throughout the development, sought to preserve and protect themselves from the various negative factors surrounding it - cold, heat, hunger, dangerous animals and insects.

Site structure "Survival in the wild nature" is simple and logical, selecting a specific section, you will find information. You will find on our website recommendations and practical advice on survival, unique descriptions and pictures of animals and plants, turn-based scheme to trap wild animals, tests and reviews of travel gear, rare books on survival and wildlife. The site also has a large section devoted to video on survival survivalist-known professionals around the world.

The main theme of the site, "Survival in the wild nature" - is to be ready to be in the wild, and the ability to survive in extreme conditions.

The Survival in the wild nature - how correctly to behave, it having appeared in an emergency situation. Ability to find a way out from any situation: to kindle a fire, to put traps, to prepare food, to arrange dwelling and a lodging for the night; to learn to knit knots, to clear water, to be guided by districts, correctly to choose equipment, a knife. Also you can download directories to tourists, encyclopedias survivals, video Bear Grills to Survive at any cost (Man vs. Wild).
