THE INTERNATIONAL SPACE STATION (ISS)
In 1984, President Ronald Reagan proposed that the United States, in cooperation with other countries, build a permanently inhabited space station. Reagan envisioned a station that would have government and industry support. The U.S. forged a cooperative effort with 14 other countries (Canada, Japan, Brazil, and the European Space Agency -- United Kingdom, France, Germany, Belgium, Italy, The Netherlands, Denmark, Norway, Spain, Switzerland, Sweden). During the planning of the ISS and after the fall of th ....etc

Experts agree that the biggest drain of energy takes place when a vehicle blasts off, pushing through Earth?s gravitational pull requires great amounts of fuel, but once they get out of our atmosphere, the rest is easy.

If you could cut out that ?blast off? portion, space travel would be easier and much more fuel-efficient.

In a Space Elevator scenario, a Maglev vehicle would zoom up the side of an exceedingly tall structure and end up at a transfer point where they?d then board a craft to the Moon, Mars, or any other distant destination ....etc

The successful exploration of space requires a system that will reliably transport payload such as personnel and instrumental etc. into space and return them back to earth without subjecting them an uncomfortable or hazardous environment. In other words, the spacecraft and its payloads have to be recovered safely into the earth. We have seen the re-entry capsules and winged space vehicles approach the earth followed by safe landing. However, this could be accomplished only after considerable research in high speed aerodynamics and ....etc

Robot is a system with a mechanical body, using computer as its brain. Integrating the sensors and actuators built into the mechanical body, the motions are realised with the computer software to execute the desired task. Robots are more flexible in terms of ability to perform new tasks or to carry out complex sequence of motion than other categories of automated manufacturing equipment. Today there is lot of interest in this field and a separate branch of technology 'robotics' has emerged. It is concerned with all problems of rob ....etc

Introduction to Nanosensors
Sensors: Instrument responds to physical stimulus, collects and measures data regarding some property of a phenomenon, object or material and Converting into a measurable quantity by data acquisition system
Extremely small device capable of detecting and responding to physical stimuli with dimensions of 1 billionth of a meter, with its ability to sense the properties of environmental conditions at very small and gaseous levels

Free space optical communications is a line-of-sight (LOS) technology that transmits a modulated beam of visible or infrared light through the atmosphere for broadband communications. In a manner similar to fiber optical communications, free space optics uses a light emitting diode (LED) or laser (light amplification by stimulated emission of radiation) point source for data transmission. However, in free space optics, an energy beam is collimated and transmitted t ....etc

The successful explortion of space requires a system that will reliably transport payloads into space and return back to earth; without subjecting them an uncomfortable or hazardous environment. In other words, the space crafts and its pay loads have to be recovered safely into the earth. The space shuttle used at older times were not re-usable. So NASA invented re-usable space shuttle that could launch like a rocket but deliver and land like an aeroplane. Now NASA is planning to launch a series of air-breathing planes that would ....etc

Robot is a mechanical body with the brain of a computer. Integrating the sensors and the actuators and with the help of the computers, we can use it to perform the desired tasks. Robot can do hazardous jobs and can reach places where it?s difficult for human beings to reach. Robots, which substitute the manned activities in space, are known as space robots. The interest in this field led to the development of new branch of technology called space robotics. Through this paper, I intend to discuss about the applications, environmental condition, ....etc
