At present, Remote Sensing, GIS and GPS have become important and effective tools in diversified studies like Geosciences, Forestry and Ecology, Soil and Agriculture, Water Resources, Urban and Regional Planning etc. During early half of the twentieth century, aerial photos were used in the application of Military Surveys and Topographical Mapping. This Aerial Photography provided high spatial resolution data in three dimensions, and used for the purpose of surveying and cadastral mapping like route alignment survey or Engineering Surveys (Dam/Bridge construction) and also for urban & regional planning. However, modern remote sensing technique is providing updated and developed satellite images which are suitable for medium scale mapping to monitor, investigate, and manage the natural resources. Due to continuous research programs in space science, the remote sensing technology has become more advanced besides its various applications. » Read more: SPACE SCIENCE
Space History at a Glance
January 10th, 2010 by Admin No comments »Britain’s contribution to space science began hundreds of years before Prime Minister Harold Macmillan announced a new British space research programme in 1959.
For centuries our scientists and astronomers have shaped how the world is seen and they continue to add to our knowledge of the Universe through space missions and ground-based science.
The following list highlights some of the most important
discoveries for science as well as key missions involving British scientists and engineers.
1668 – Sir Isaac Newton builds the first reflecting telescope. Over 300 years later, Newton’s invention forms the basis of the Hubble Space Telescope. » Read more: Space History at a Glance
Space elevator
January 2nd, 2010 by Admin No comments »A space elevator is a proposed structure designed to transport material from a celestial body’s surface into space. The concept of a space elevator dates back to 1895 when Konstantin Tsiolkovsky[1] proposed a free-standing “Tsiolkovsky” tower reaching from the surface of Earth to geostationary orbit. Most recent discussions focus ontensile structures (specifically, tethers ) reaching from geostationary orbit to the ground. Spaceelevators have also sometimes been referred to as beanstalks, space bridges, space lifts, space ladders, skyhooks, orbital towers, or orbital elevators.
