  1. 1. REMOTE SENSING IN SPACE Presentation By Krishna Gaihre BEX/066/422
  2. 2. What is Remote Sensing? • Remote sensing is the science(and to some extent, art) of acquiring information about the Earth's surface without actually being in contact with it. This is done by sensing and recording reflected or emitted energy and processing, analyzing, and applying that information. Elements of Remote Sensing : 1. Energy Source or Illumination (A) 2. Radiation and the Atmosphere (B) 3. Interaction with the Target (C) 4. Recording of Energy by the Sensor (D) 5. Transmission, Reception, and Processing (E) 6. Interpretation and Analysis (F) Application (G)
  3. 3. Remote sensing Elements
  4. 4. Application Of Remote Sensing • Space Exploration(Moon , Mars ,Sun ,…) • Environmental monitoring • Scientific assessment of meteorological images • Measure the solar incident radiation on ground • Land Cover • Data pertaining to the coastal zone • Delineation of coastal landforms and tidal • Impact of deforestation on global climate • Agriculture
  5. 5. New Technology Trends in Remote Sensing 1. Miniaturization of electronics 2. High-performance onboard computing 3. Large, lightweight structures 4. Increased power active sensing 5. Compact optics 6. Frequency flexibility Figure:-Light weight Space –craft

  10. 10. What is IRIS Designed to do? • Understand the Sun and its effects fundamental physical process of the space on Earth and the solar system. • Develop the capability to predict the extreme and dynamic conditions in space in order to maximize the safety and productivity of Human and robotic explorers.

  14. 14. Sciences and Exploration • Understanding of energy transport into the corona and solar wind. • Advance Sun-Earth connection studies by tracing the flow of energy and plasma into the corona and heliosphere . • IRIS obtains high, resolution UV spectra and images of the sun's chromosphere • IRIS will obtain UV spectra and images with high resolution in space (1/3 arcsec) and time (1s) focused on the chromosphere and transition region of the Sun, a complex dynamic interface region between the photosphere and corona.
  15. 15. What Can IRIS Do? The extreme ultraviolet image of the sun was taken by the Solar Dynamics Observatory (SDO). This tri-color composite image traces different gas temperatures. Reds being cooler and blues hotter. IRIS will use ultraviolet images of the chromosphere and transition region (shown in the simulated IRIS image insert) to similarly diagnose conditions in the interface region. IRIS uses spectroscopy (overlayed graph) to learn about the detailed flow of energy and gases.
