Slide 2: Space craft & its emission gases
Slide 3: What is Space craft?
Slide 4: A SPACECRAFT is a machine designed for placing a satellite into the orbit by human for some purpose Space craft Artificial Satellite
Slide 5: DO YOU KNOW
THE FIRST
ARTIFICIAL SATELLITE LAUNCED BY
HUMAN ?
Sputnik 1, launched by the Soviet Union in October 4th, 1957. : Sputnik 1, launched by the Soviet Union in October 4th, 1957.
Slide 7: MODERN SATELLITES
Slide 8: SPACECRAFT ARE USED FOR A VARIETY OF PURPOSES
EARTH OBSERVATION
METEOROLOGY (Weather , Season Changes & Global Warming)
COMMUNICATIONS
NAVIGATION
PLANETARY EXPLORATION
SPACE TOURISM
Slide 9: IMPORTANCE OF SATELLITES satellite Fig-1 Clock wise:1-Melting of icebergs; Climate; Global warming; Dust storms; Forest fire; Volcanoes;& Earth images
Earth Observation : Earth Observation
Slide 11: Satellite Image of Loktak Wetland Manipur Satellite View of Manipur Loktak Lake Loktak Wetland
Area - 258 sq km
Satellite View : Largest Freshwater Lake in NE India-The Loktak Lake Satellite View Sarychev volcano (Russia’s Kuril Islands, northeast of Japan) is one of the most active volcanoes.
Slide 13: METEOROLOGY
(CLIMATE &WEATHER FORECAST)
The Sentinel Satellites for Weather Forecast : The Sentinel Satellites for Weather Forecast Sentinel-1 :It is an all-weather, day/night radar imaging satellite mission for land and ocean services.
Sentinel-2: It is a mission to provide high-resolution, multi-spectral images for land-based services. The sentinel satellites -1 The sentinel satellites -2
Slide 15: SEASONAL CHANGES Pre-monsoon season March-May Winter season Jan-Feb
Slide 16: Post Monsoon Season Oct-Dec Monsoon Season June- Sep
Communications : Communications
Communication in everyday life : Communication in everyday life
Slide 19: SATELLITE & VARIOUS COMMUNICATION TOOLS CABLE TV EAST- WEST or NORTH-SOUTHWe enjoy watching TV of world channels by cable networkWe can keep in touch with our family & friends USING THE ABOVE TECHNOLOGIES WEBCAM SATELLITE
Slide 20: NAVIGATION
Global Navigation Satellites System (GNSS) : Global Navigation Satellites System (GNSS)
GNSS PURPOSES : GNSS PURPOSES Help Aircrafts And Ships To Identify Their Exact Locations
Provide Autonomous Geo-spatial Positioning With Global Coverage
For Military Applications
The United States Global Positioning System (GPS) is Currently The World's Most Utilized Satellite Navigation System.
It Consists Of Up To 32 Medium Earth Orbit Satellites In Six Different Orbital Planes
PLANETARY EXPLORATION : PLANETARY EXPLORATION
Planetary Exploration is a timeline of Solar System exploration listed by date of spacecraft launch : Planetary Exploration is a timeline of Solar System exploration listed by date of spacecraft launch To find any traces of life supporting elements in outer space planets, mainly the planet Mars
SPACE TOURISM : SPACE TOURISM
Slide 26: Space tourism is the phenomenon of tourists paying for flights into space spending up to $25 million for a chance to travel in low Earth orbit (LEO) and beyond to see the earth from the space.
California multi-millionaire Dennis Tito spent $20 million on space tourism to become the first paying tourist, in 2001. where he spent 7 days aboard the International Space Station (ISS).
Impact on Environment from emission of gases from space craft : Impact on Environment from emission of gases from space craft
Slide 28: Stratosphere : The 2nd layer of atmosphere 12 - 48 km above the earth's surface.
It contains gas ozone (O3), which filters about 99 % of the incoming harmful ultraviolet (UV) radiation before reaching to earths’ surface. BUT! Space crafts emission gases to stratosphere causes major damages to ozone layer.
Slide 29: Release Of Ozone depleting substance (ODS) Gases From Space Craft e.g. Nox, Sox, Co2,co, Ch4, Cfcs Etc. Leads To Global Warming, Ozone Depletion, Acid Rain, Harmful Skin Diseases & Green House Effect (GHE) . Antartic Ozone hole is one example of GHE.
Also Burning Of Fossil Fuels For Transportation (Driving And Flying) And Home Energy (Electricity, Heating, And Cooling) Also Causes Green House Effect And Global Warming Too.
Slide 30: Space technology plays vital tools in helping us to better understand
Global warming & green house effect
Climate change & events such as hurricanes and windstorms which could give rise to floods
Depletion of the ozone layer
They track the world’s weather patterns
Give long-range weather forecasting capability
Warn of Earthquakes, volcanic eruptions, landslides and forest fires are also often visible from space, and satellites provide us with a tool, if not for prevention, at least for rapid response. CONCLUSION
