Dear Students👨‍🏫
what we have learnt in this chapter are:-
Man-made objects revolve in a certain orbits around the earth or other plancts are called the artificial satellites.
The minimum velocity by which an object thrown upwards and crosses the gravitational attraction forever, is called the escape velocity.
The escape velocity for carth is 11.2 km/sec.
The satellite which is scen at fixed position viewing from same location is called geo-stationary satellite. The geo- stationary satellite is also called communication satellite.
Those satellite revolve in polar orbits of earth is called polar satellites.
The polar satellites send information's and data related to climate, geology, earth-water, etc. over passing through various positions at different times and locations in a day.
The artificial satellites proved their utility in telecommunication sector, climate information and waming alerts, scientific research, to identify water and minerals geological repositorics, surveying the forest areas, spying, identifying the location of person and mobile, etc.
The first Indian artificial satellite ' Aryabbatt' was launched in April 19, 1975 from Baikonur space centre of earlier Europian union.
Indian space research organization (ISRO) is doing an important work in manufacturing and developing of artificial satellite and satellite launching vehicles and also satellite launching and space science.
